Anilox Roller's Type and Structure

The anilox roll is a very important part in the ink transfer part. What is the structure of anilox roll? What are its categories?

From the view of surface structure, it is mainly composed of roll core, substrate and surface coating. The base material commonly used is electroplating copper, which is the basis for making anilox roller unit. The surface coating is made of metal chromium or ceramic, which is mainly used to improve the wear resistance of anilox roll and prevent the corrosion of solvent.

Classification of anilox roll

According to the different surface coating of anilox roll, it can be divided into metal chrome anilox roll and ceramic anilox roll. From the comparison of engraving accuracy, printing resistance, ink transfer performance and ink release performance, ceramic anilox roller has more advantages.

The picture followed is customized knife shaft made by Futian Roller.

2. The anilox roll can also be classified according to the ink shape on it. There are several common ink hole shape: hexagonal prism, quadrangular pyramid, quadrangular prism, trapezoidal section, and additional channel ink hole. The opening and depth of the ink hole have a considerable impact on the ink transfer performance of the anilox roll. The greater the opening and the shallower the depth, the better the ink transmission. Among the above ink shape, the hexagonal inking hole has a large opening, so the inking and inking performance is good, so this shape of ink is often used.

3.The number of lines of the anilox roll is one of the important parameters of the anilox roll. It refers to the number of ink holes per unit length on the surface of the anilox roll, which also has a very important impact on the ink transfer. In general, the higher the number of lines on the anilox roll, the smaller the amount of ink transferred. In addition, the anilox roll with different number of lines also has different application scope. When printing areas are large, you can consider using an anilox roller with a small number of lines. On the contrary, when printing fine images or small characters and lines, the anilox roller with higher number of lines should be used.

Hope this article will help you get some information about anilox roller. If you are interested in anilox roller or other rolls, please click Futian Roller for more or contact us directly.

What Is Anilox Roller

Anilox roller, a type of roller common used during printing process. The anilox roll is a hard steel or aluminum cylinder coated with industrial ceramics. The surface of the anilox roll is laser carved with very small dips, forming anilox. The engraving pattern on the anilox roller will affect the anilox efficiency, so it is very important to select the engraving pattern to provide the best effect. In the printing process, a certain amount of ink is coated on the anilox roll, and then rolled on the raised part of the printing plate to achieve the printing effect.

The picture following shows steel conveyor roller made by Futian Roller.

How to clean anilox rollers?

Cleaning the anilox roll is an important part of its maintenance. If cleaned regularly, the anilox roll will be more durable with better ink transfer and reliable reuse rate. There are several methods and techniques for cleaning the anilox roll:

Chemical cleaning method: Clean the anilox roll regularly with chemical solvent. Except chemical solvent, for further cleaning, the roller shall be thoroughly cleaned and scrubbed with a chemical cleaner that can penetrate the ceramic surface. The anilox roll can also be cleaned with special solvent for ink,heated by specific cleaning machine, after which the residue on the roller surface will be dissolved by cleaning agents.

Sand blasting technology of anilox roller: This cleaning technology uses powder to spray dry ink and other debris.

Ultrasonic cleaning technology: During this cleaning process, the anilox roller rotates in the heated chemical solution. When the anilox roller contacts with the bubbles generated by the ultrasonic wave, the bubbles implode and release the pressure and temperature to dissolve and remove the debris on the surface of the roll. This method is very effective for most inks used in flexographic printing.

The article above is a brief introduction of anilox roller and its cleaning method. When it comes to the anilox roller, we not only focus on its precision, but we also pay attention to the quality of it to ensure its accurate and long-term operation. As a China roller manufacturer, Futian Roller also provide a line of other rollers, such as embossing roller, mirror roller, tungsten carbide coated roller, and so on.

What Is an Idler Roller

Idler rollers are cylindrical parts used in conveyor belts. Pulleys and idler rollers are very similar. Generally, idlers are mainly used to support the conveyor belt, but there are also some idlers that can be used to transport goods.

Generally, conveyor idlers are used to move the belt and help drive the belt system. The idler rollers can also provide resistance within the belt and pulley structure. Some types of conveyor idlers may have the function of belt tensioner. When being moved, these idler rollers can change the tension on the belt of the conveyor.

This is a picture of conveyor idler rollers made by FUTIAN ROLLER, exported to Japan.

As an important part of many industrial equipment and conveyor systems, the conveyor roller has the following types: in-line idler, inset roller and offset roller, and return idler. The construction methods of in-line idler roller, inset roller and offset roller are special so that the idlers can accommodate the conveyor belt according to the best factors. The return idler roller is often used to drive the reverse moving belt. They can help control the drive and functions that contribute to the conveyor belt as well as the return belt, such as the width or tension between the top belt and the return belt. 

There are some specific types of conveyor idler that consist of several rollers, where each part of the idler roller is connected to the belt at different points to keep the belt operating correctly and well. Some idlers have adjustment handles to help the belt move correctly. All these show the versatility of the idler structure and ensure the normal operation of the industrial conveying system.

Conveyor rollers are widely used in daily life and different industries. Futian Roller can produce customized idler rollers according to customer’s drawing and requirements. Please feel free to contact Futian Roller if you need customized conveyor roller, idler rollers, conveyor pulley, drum pulley, tension roller, return roller, drive drum, etc.

Zinc Plated Roller

To enhance the properties, usually industrial rollers need surface treatment. Zinc plating is one of the most commonly used. Zinc plating roller is coating the roller surface with a zinc layer by using a current of electricity.

What are the benefits of zinc electroplating to rollers?

1. Corrosion protection: The zinc layer on the metal roller will form a protective zinc oxide layer after being exposed to air and water, which can protect the roller from being rusted, improve the corrosion resistance, and extend its service life.

2. Luster finishing: Zinc electroplating is always used to improve the roller appearance. The metal roller with zinc plating looks shiny and smooth. A range of colors are available in zinc plating, which makes it adaptable to more applications.

The picture following is customized zinc plated steel roller for printer, made by FUTIAN ROLLER.

3. Cost effective: As an element, zinc is abundant and more affordable metal applied in electroplating. Zinc plating is a low cost electroplating process. At the same time, the zinc coated roller can be used in a wide range of applications. Thus, zinc plating is a great alternative for industrial rollers.

What is zinc plated roller used for?

The zinc plated steel rollers manufactured by FUTIAN ROLLER are widely used in printing machines, conveying equipment, logistics conveyor systems, textile machinery, automatic systems, etc.

Hoping this article will help you understand the benefits and application of zinc plated roller. Besides zinc plated steel rollers, FUTIAN ROLLER can also manufacture hard chrome plated roller, nickel plated roller, Teflon coated roller, rubber covered roller, mirror finish roller, heat transfer rolls, cooling roller, vacuum rollers, etc. If you are interested in precision industrial rollers, you can click FUTIAN ROLLER for more information.

What is the Working Temperature Range of Teflon Roller?

Teflon coating is widely applied in roller surface treatment due to its advantages of resistance to extreme temperatures. What is the working temperature range that Teflon roller can withstand? Futian roller will briefly introduce the high temperature and low temperature resistance of Teflon coated rollers.

What is the highest temperature can Teflon roller withstand?

1. The PTFE Teflon roller can generally operate continuously at 260 ℃, which is the maximum continuous temperature. While it can also withstand the maximum intermittent temperature of 400 ℃.

2. We need to know that due to the different types of Teflon coatings, the temperature of Teflon coating rollers that can withstand will also change. For example, PTFE can withstand the high temperature up to 260 ℃, while PFA can only withstand high temperature up to 200 ℃, so we need to select the appropriate Teflon coating for surface treatment of the roller according to the specific application. In fact, the Teflon roller is relatively stable at room temperature, but once the ambient temperature exceeds the acceptable temperature range, the Teflon coating will become unstable and decomposed.

The picture below is customized Teflon rollers made by FUTIAN ROLLER.

What is the lowest temperature can Teflon roller withstand?

Teflon coating can withstand both high temperature and low temperature. The roller sprayed by Teflon can operate at -190 ℃ for a long time. However, due to thermal expansion and contraction, the Teflon coated rollers will deform. Generally, the safe and effective working temperature of Teflon roller is - 70 ℃.

This article is a brief summary about the working temperature range of Teflon roller. Teflon rollers/ PTFE rollers made by Futian Roller are widely used in digital printing industry, textile industry machinery, etc. Besides Teflon coating rollers, Futian Roller can also produce customized hard chrome plated roller, electroless nickel plated roller, zinc plated roller, anodized aluminum guide roller, mirror finish roller, plasma coated roller, etc. Please feel free to contact Futian Roller if you need industrial rollers.

Inspection Standards for Rubber Rollers

Rubber roller (also called rubber cylinder, rubber roll), is a product made of roller core and the rubber layer that covers on the core. Rubber coated rollers are widely used in printing, paper making, textile, converting, plastic film, grain processing, metallurgy, logistics and other industries. The inspection standards of rubber rollers mainly include rubber hardness, roller precision, roller surface roughness, wear resistance, aging resistance, high temperature resistance, low temperature resistance, impact performance, tensile performance, thermal conductivity, corrosion resistance, electrical properties, resilience, etc. In this article, FUTIAN ROLLER will briefly introduce the inspection of rubber hardness, roller precision, aging resistance and elasticity of rubber roller.

1、Rubber hardness

The rubber hardness of the roller refers to the performance of rubber roller’s resistance to the measuring instrument probe under given conditions. The hardness of rubber roller, which is usually expressed by Shore hardness, will affect its functions such as shock resistance and adhesion. However, it should be noted that higher hardness of rubber roller does not mean better quality. In some industries, rubber roller of low rubber hardness is more favorable.

The picture following is customized wide format EPDM rubber coated rollers for printing machine made by FUTIAN ROLLER.

2、Precision of rubber roller

1) Diameter of rubber roller: the diameter is usually measured with micrometer, vernier caliper, etc.

2) Roller cylindricity: the cylindricity of small rubber rollers can be measured on equipment such as three coordinates. While currently there is no rather good way to measure the cylindricity of larger rollers directly. Generally, we use the maximum difference between the change of roller diameter and runout as the roller cylindricity data. Now the cylindricity of rubber coated roller manufactured by Futian Roller is not more than 0.05mm.

3) Runout of roller: in the inspection standards of rubber rollers, the circular run-out represents the shaking degree of rubber coated roller during operation, which is usually measured with a dial indicator.

3、Aging resistance of rubber roller

To test this performance, it mainly needs to prolong the ultraviolet light treatment time, and generate high temperature to aggravate the oxidative cracking of the rubber roller. Then the aging resistance can be obtained by recording the aging time and degree of the rubber roller.

4、Elasticity of rubber roller

Pressurize the rubber roller in the static state until indentation occurs, and record the time when the indentation disappears. The shorter the time, the better the elasticity is.

It should be noticed that affected by changes of environmental factors such as temperature and humidity, the performance of rubber coated roller will change accordingly. Therefore, the rubber cylinder’s performance must be measured and compared in the same conditions.

Futian Roller can produce customized polyurethane rubber covered rollers, silicone rubber sleeves, EPDM rubber rollers, NBR, SBR, Hypalon rubber rolls and other types of rubber coated rollers. If you need customized rubber covered roller or more precision rollers, please feel free to contact FUTIAN ROLLER.

Rubber Roller's Proper Use And Maintenance

Proper use and maintenance of rubber roller can prolong the service life of it, improve the durability and production efficiency. In this article, FUTIAN ROLLER will discuss the correct use and maintenance of rubber roller. ​

Correct use of rubber roller

Assemble the bearings properly

Select the bearings whose specifications and models meet the design requirements. During bearing assembly, apply a layer of lubricating oil on the surface, and then use the special sleeve to evenly force the bearing, so that it can be installed in place smoothly. In order to avoid damage to the bearing, do not apply force directly on the bearing surface.

The picture below is customized EPDM rubber coated transport roller made by FUTIAN ROLLER.

2. Regulate the working pressure of rubber roller

In the process of operating, proper pressure must be maintained between rubber rollers and the machines.

3. Check the rubber roller and bearings regularly

Check the quality of rubber roller and bearings regularly, if the bearing becomes flexible, it must be replaced immediately. If the roller doesn’t work well, it should be repaired or replaced.

Maintenance of rubber roller

1. Keep lubricated

Rubber coated rollers should be lubricated regularly. Or it will cause the wear of roller shaft head and bearings and lead to the poor production quality. If there is no effective lubrication during operation for a long time, it will also cause the heating of the bearing and shaft, which will lead to the rubber surface worn and crack.

2. Cleaning of rubber roller

The surface of high quality rubber roller is generally smooth and clean. However, due to the long-term contact with industrial materials, the rubber roller surface will inevitably have residues accumulated. So in daily maintenance of rubber roller, cleaning should be attached great importance to.

3. Regular maintenance 

After 2 to 3 months of use, the diameter of rubber roller will gradually become smaller, which will affect the accurate transmission of production materials. Now the rubber roller shall be maintained and the pressure between rollers shall be readjusted.

This article is about rubber roller’s proper use and maintenance, if you have more questions about rubber covered roller, please feel free to contact FUTIAN ROLLER.

Reason Analysis for Degumming of Polyurethane Rubber Roller

The article followed will list some reasons of rubber layer’s degumming.  

Polyurethane rubber rollers have many great features: high mechanical strength, good resistance to wearing, aging, oil, etc. Due to these advantages, PU rubber rollers are widely used in conveyor system, paper making, chemical fiber, plastic machinery, etc. But sometimes you may encounter the situation of polyurethane rubber roller degumming. In this article we will analyze the reasons for degumming.

Reasons for degumming of PU rubber roller:

1、Low temperature of polyurethane adhesive will make the curing time not balanced during the molding of PU rubber roller.

2、The PU rubber roller is easily affected by external forces when it is just be de-moulded. If the de-moulding operation is improper, the polyurethane rubber roller is easy to be unglued in future use.

The picture following is customized PU rubber coated conveyor rollers for logistics conveyor system.

3、If the adhesive of roller core is not evenly applied or the formula is not suitable, the polyurethane rubber layer and the roller core will not bond firmly, which will leads to the degumming.

4、Blisters at the roll core because of improper casting procession will also have the possibility of rubber degumming.

5、The urethane roller core is not cleaned completely after sand blasting.

6、The preheating temperature of the roll core is improperly controlled.

In order to avoid degumming, we need to pay attention to the following aspects:

1、Select appropriate adhesives to bond PU rubber layer and the roller core.

2、The surface of the roller core must be clean and dry. And increase the surface roughness by sandblasting.

What Is Electromagnetic Heating Roller

The electromagnetic heated roller is a type of heating transfer roller, which is made according to the principle of electromagnetic induction heating. Compared with the traditional oil heated roller and electric heating roller, the electromagnetic heating roller has the advantages of high temperature, good heating uniformity, and low energy consumption. The electromagnetic heated roller can be used in the surface calendering of various textiles and foaming materials, drying and stretching of films and various materials, etc.

Technical principle of electromagnetic heated roller:

Electromagnetic heated roller is a kind of roller which can heat itself in the continuous processing and production of industrial materials. The basic principle of its heating is to use the coil inside the roller to generate electromagnetic field, and by cutting the metal surface with magnetic line the roller can heat itself. The roller surface then exchanges heat with the material to be processed, and maintains the set working temperature of the roller through the temperature control system of the closed loop.

The picture following is customized roller made by FUTIAN ROLLER.

Compared to traditional heating roller, electromagnetic heated roller has several advantages:

1) The electromagnetic heating roller can work stably at a temperature of 350 ℃, breaking through the temperature bottleneck of traditional heating transfer roller, and meeting the temperature requirements of high-performance materials.

2) Because of its structural characteristics and excellent performance, the heating roller can keep the temperature of the roller surface accurately controlled during operation. It can also control the temperature change range according to the needs of special processes to ensure the quality of materials, reduce the waste of production caused by temperature changes;

3) It has remarkable energy-saving effect and cost of its maintenance is low. Compared with the traditional oil heated roller, the electromagnetic heating roller can be reduced by 50% or more. The complex heating equipment is abandoned, which can greatly reduce the heating power consumption;

4) When using the electromagnetic heating roller, there is little pollution, because it does not need heat transfer medium such as heat transfer oil or steam, which completely eliminates the pollution and potential safety hazards caused by medium leakage.

Solutions to Common Problems of Rubber Roller

Rubber rollers are widely used in paper making, printing and dyeing, printing, grain processing, metallurgy, plastic processing and other industries. In practical application, the rubber roller may break down due to some reasons. The following article will describe some common problems encountered in the use of rubber roller and repairing solutions to solve these problems.

1.Rubber roller surface crystallization and calcification: the surface of high-quality rubber roller should be smooth, slightly sticky, with good ink transfer performance. During production, the rubber has been affected by fountain solution, ink, paper and other factors for a long time. In addition, each cleaning cannot be very thorough. The remaining impurities will be piled up on the rubber surface. As time goes by, the original pores on the rubber surface will be closed, forming a smooth crystal layer similar to calcium, which seriously affects the ink transmission and water transmission performance, and cause unstable control of the ink color of printed products. In order to avoid this situation, after washing the rubber roller, use some citric acid water to wash it again, so that some calcium impurities on the surface of the rubber roller will react chemically, forming soluble substances for cleaning.

2. The surface of the rubber roller is prone to be scratched: On account that the rubber cylinder is relatively soft, it will easily get scratched during high-speed operation. Once there are scratches, the rubber roller can no longer be used. To avoid such failures, to check whether the printing plate is tightened or clamped by the plate clamp is important. Meanwhile, check whether the ink is not maintained in time. Impurities such as ink peel and ink residue will accelerate the friction, heating and aging of the rubber roller and make the rubber surface covered with pockmarks. This situation is generally serious at both ends of the rubber roller. 

3.Premature chapping and aging of rubber roller: There are many reasons for this. Firstly, excessive dry oil in the ink will make the ink dry and cause heat on the rubber roller; Second, the detergent used for cleaning the rubber is not properly selected, and the cleaning time is too short will also make the impurities on the rubber not be completely cleaned; Thirdly, the ambient temperature of the workshop is so high that a large amount of heat generated during the operation of the rubber roller cannot be released in time, which will make the internal temperature of the rubber roller too high. In order to avoid premature break down of rubber rollers, working environment should be ensured to be proper for rubber roller. By ensuring good working environment and operating conditions, the service life of the rubber roller can be extended, which can reduce industrial costs and improve economic benefits.

Above are the solutions to common problems of rubber roller, hope it can help you. Please feel free to contact FUTIAN ROLLER if you need customized rubber rollers.

Factors Affecting the Service Life of Rubber Roller

Rubber rollers are widely used and play an important role in many industries. Rubber coated rollers are intended to last a long period of time. But the service life of rubber roller is not only related to raw materials, but also has a lot to do with roller maintenance. Proper care and maintenance can ensure good working performance and reduce costs.

The following factors affect the service life of rubber rollers:

1. Quality of rubber. The industrial rubber roller is a vulnerable item. If the quality of the rubber is not good, it can be expected that the service life of the rubber roller will be shortened.

2. Daily use methods: The roller life is also closely related to the daily use methods. If the equipment is not cleaned or maintained well in daily production, it will cause greater damage to the roller and equipment.  

The picture below is rubber coated roller made by FUTIAN ROLLER.

3. Proper installation: Installation of the rubber roller is a very key step. Properly install the industrial rubber roll bearing, generally including the appropriate tightness between the roll neck and the bearing. In order to save costs, many users often install bearings by themselves. In fact, there are some small accessories between the shaft head and the bearing of industrial rubber rollers, which are used to maintain the dynamic balance of rubber rollers, so that the rubber rollers can better display their balanced quality. If the rubber roller is not installed in proper way, it will do damage to the rubber rollers.

4. Timely cleaning: After using the rubber cylinder rollers every day, carefully cleaning them is a significant step to prolong the service life of the rollers. When cleaning, special cleaning agent should be selected. Avoid using the solvent that corrodes the adhesive for cleaning, and check whether there are impurities left on the rubber. Impurities generally need to be wiped. If they are not cleaned regularly, the surface of the rubber rollers will be uneven and deformed, which affects the smooth operation of the rubber roller.

The article above is about factors that affect the rubber roller life. If you are interested in customized rubber covered roller, please contact FUTIAN ROLLER.
