Automatic blow molding machine PLC

Automatic blow molding machine PLC is a kind of equipment used for industrial production automation control. Generally, it can be directly used in an industrial environment without any measures. However, despite the high reliability and strong anti-interference ability as mentioned above, when the production environment is too bad, the electromagnetic interference is particularly strong, or the installation and use are improper, it may cause program errors or calculation errors, resulting in misinput and Causes false output, which will cause loss of control and malfunction of the equipment, which cannot guarantee the normal operation of the PLC.

To improve the reliability of the PLC control system, on the one hand, the PLC manufacturer is required to improve the anti-interference ability of the equipment; on the other hand, it is required to attract great attention in the design, installation, and use and maintenance, and the cooperation of multiple parties can solve the problem and effectively enhance the anti-interference ability of the system. Interference performance. Therefore, the following issues should be paid attention to during use: 1. Working environment (1) Temperature PLC requires an ambient temperature of 0~55oC. It cannot be placed under components with large heat generation during installation. The surrounding ventilation and heat dissipation space should be large enough. (2) Humidity In order to ensure the insulation performance of the PLC, the relative humidity of the air should be less than 85% (no condensation). (3) Vibration should keep the PLC away from strong vibration sources and prevent frequent or continuous vibration with a vibration frequency of 10 to 55 Hz. When vibration is unavoidable in the use environment, shock-absorbing measures must be taken, such as shock-absorbing glue.

(4) The air should avoid corrosive and flammable gases, such as hydrogen chloride and hydrogen sulfide. For environments with a lot of dust or corrosive gas in the air, the PLC can be installed in a control room or control cabinet with better enclosed properties. (5) The power supply PLC has certain resistance to the interference caused by the power line. In environments with high reliability requirements or severe power interference, an isolation transformer with a shielding layer can be installed to reduce the interference between the equipment and the ground. Generally, the PLC has a DC 24V output provided to the input terminal. When the input terminal uses an external DC power supply, a DC stabilized power supply should be selected.

2. Interference and its sources in the control system (1) Interference sources and general classification The interference sources that affect the PLC control system are mostly generated in the parts where the current or voltage changes drastically. The reason is that the current change generates a magnetic field and electromagnetic radiation to the equipment; The change of the magnetic field produces electric current, and the electromagnetic produces electromagnetic waves at high speed. Generally, electromagnetic interference is divided into common mode interference and differential mode interference according to different interference modes. Common mode interference is the potential difference between the signal and the ground. The common mode voltage can be converted into a differential mode voltage through an asymmetric circuit, which directly affects the measurement and control signal and causes component damage. This common mode interference can be DC or AC. Differential mode interference refers to the interference voltage acting between the two poles of the signal, which is mainly caused by the coupling and induction of the spatial electromagnetic field between the signals and the voltage formed by the unbalanced circuit converting the common mode interference. This interference is superimposed on the signal and directly affects the measurement and control. Accuracy.

(2) The main source and path of interference in the PLC system. Strong current interference. The normal power supply of the PLC system is powered by the grid. Due to the wide coverage of the power grid, it will be subject to electromagnetic interference from all spaces and induce voltage on the line. Interference in the cabinet The high-voltage electrical appliances in the control cabinet, large inductive loads, and chaotic wiring are likely to cause a certain degree of interference to the PLC. The interference introduced from the signal line and the various signal transmission lines connected to the PLC control system, in addition to transmitting effective various types of information, there will always be external interference signals intruding. There are two main ways of this interference: one is the power grid interference through the power supply of the transmitter or the power supply of the shared signal instrument, which is often ignored; the other is the interference of the signal line by electromagnetic radiation induction in space, that is, the signal line The external inductive interference is very serious.

The interference introduced by the signal will cause the I/O signal to work abnormally and the measurement accuracy will be greatly reduced. In severe cases, it will cause component damage. Interference grounding from the chaos of dianya blow molding machine the grounding system is one of the effective means to improve the electromagnetic compatibility (EMC) of electronic equipment. Proper grounding can not only suppress the influence of electromagnetic interference, but also restrain the equipment from sending out interference; and wrong grounding will introduce serious interference signals and make the PLC system unable to work normally.

The interference from the PLC system is mainly caused by the mutual electromagnetic radiation between the internal components and circuits of the system, such as the mutual radiation of logic circuits and their influence on analog circuits, the mutual influence of analog ground and logic ground, and the mutual mismatch between components Use etc. 3. Conclusion The interference in the PLC control system is a very complicated problem.

Therefore, various factors should be considered comprehensively in the anti-interference design, and the anti-interference should be suppressed reasonably and effectively to make the PLC control system work normally. With the continuous expansion of PLC application fields, how to use PLC efficiently and reliably has also become an important factor in its development. In the 21st century, PLC will have greater development, product varieties will be richer, and specifications will be more complete. As an important part of the automation control network and the international general network, PLC will play an increasing role in the field of fully automated control.

Environmental requirements of the blow molding machine's electrical system

The blow molding machine manufacturer tells you the environmental requirements of the blow molding machine's electrical system. 1. Although the temperature change of the equipment is not particularly strict, the electrical automatic control system based on PLC is not particularly strict in the environment, but in hot and humid places, The environment of many blow molding factories may not be suitable or meet the requirements of the electrical automatic control system for the working environment. The temperature of the blow molding equipment production site may reach 50-60 degrees, and the temperature of the electrical cabinet may reach 60-70 degrees. If the operating time is too long under this temperature condition, it will cause greater harm to electrical components. 

From the measured air humidity, the air humidity in many places is above 85% on many days of the year, and the moisture in the air is easy to condense into small water droplets. These small water droplets combine with the dust particles in the air, which is very It is easy to cause damage to electrical control components, leading to control failure or electrical equipment accidents.

The temperature of the blow molding equipment production site may reach 50-60 degrees, and the temperature of the electrical cabinet may reach 60-70 degrees. If the operating time is too long under this temperature condition, it will cause greater harm to electrical components. 

From the measured air humidity, the air humidity in many places is above 85% on many days of the year, and the moisture in the air is easy to condense into small water droplets. These small water droplets combine with the dust particles in the air, which is very It is easy to cause damage to electrical control components, leading to control failure or electrical equipment accidents. To deal with the environment where the ambient temperature and air humidity are too high, it is necessary to ensure the stability of the electrical control components. At present, the better method is to install an air conditioning system on the electrical cabinet of the hollow blow molding machine, which can effectively reduce the temperature of the electrical cabinet and also The air humidity in the electrical cabinet can be reduced. Judging from the actual installation of the air conditioner, it is not possible to blow the air conditioner directly into the electrical cabinet. This is likely to increase the internal humidity and cause direct harm. 

A better method is to build a relatively small and sealed space around the electrical cabinet, and use air conditioners to reduce the temperature and humidity of this space to a more appropriate range, which can effectively ensure the working stability of the electrical control system. Second, the cleanliness of electrical cabinets Although electrical cabinets are generally made relatively sealed, and many parts and components are also dust-proof, the fine dust particles in the air in the production workshop will always deposit on the surface of electrical parts and some contacts. On the surface, excessive deposition will affect the performance of electrical equipment, so regular cleaning of the electrical cabinet is essential to ensure the long-term normal and stable operation of the equipment. 

Bottle making machine factory should formulate detailed and clear systems, stipulate the cleaning methods used, and regularly clean the electrical cabinets. When cleaning the parts of the electrical cabinet, a small brush and a hair dryer can be used together. For the contact surface of some electrical connectors, you can use a clean cotton ball dipped in a little alcohol to scrub, and then plug it in after it evaporates completely. Back to the original place. When cleaning, the screws at the wiring should be tightened to ensure good contact.

If It's not good when bottle blown

The engineer said that the bottle and the mold can't match or can be distinguished with a naked eye, which means that the bottle is indeed broken. If the pressure of the bottle is normal, it is ok. Check the setting of the exhaust time. If the bottle is often blown, it is not good. The engineer said that the bottle and the mold do not match or can be distinguished by naked eyes, then the bottle is indeed broken. If the pressure of the bottle is Normally, it is possible. Check the setting of the exhaust time. If the exhaust setting is normal, and the explosion sounds every time a bottle is blown, then it can be judged that the exhaust valve is faulty. Please open the exhaust valve to check the condition of its spring box seal, ( Another phenomenon of this kind of failure is the sound of unclean exhaust). The best way is to change one. If the tube blank blushes out, then reduce the temperature, or increase the speed. If the tube blank is not blushed out and the bottle is blown out to blush it is the temperature is low, just the opposite of the previous one.

What should I do if there is excess meat after the bottle is ready? There are mainly two places on the bottle mouth and the bottom of the bottle. If there is residual meat on the bottom of the bottle, the temperature of the bottom of the bottle is low and the temperature of the bottle is high. Please lower the temperature of the bottle and increase the temperature of the bottom of the bottle. Or appropriately reduce the delayed blowing time. There is residual meat at the mouth of the bottle, which is the opposite of the residual meat at the bottom of the bottle. After the bottle is formed, one side is thick and the other side is thin. Sometimes the bottom of the bottle is not in the center. You should check whether the eccentricity of the tube blank is acceptable. Adjust the stretch rod to the center of the bottom of the mold. After adjustment, increase the blowing time appropriately. A long term used PET bottle making machine is necessary.

The main reason for the unstable weight of bottle blow molding machine

The main reason for the unstable weight of the bottle blow molding machine

1. In production, the temperature control is inaccurate or the temperature deviation is large. The installation position of the temperature measuring point (thermocouple) is unreasonable, which causes periodic deviation of the temperature. As the temperature deviation increases, the deviation affecting the weight also increases. As the temperature rises, the extrusion barrel stretches more. In the same operating cycle, the spout at the bottom of the bottle increases and the product weight decreases. When the temperature is low, the weight of the product increases. When the thermocouple is in poor contact, there is a similar failure. If the thermocouple is broken, the amount of extrusion decreases, and when it is below the melting point of the plastic, the motor current increases. It cannot be extruded below the melting point of plastic. Whether the installation position of the thermocouple is reasonable and the size of the temperature control area of ​​the thermocouple measurement point will directly affect the extrusion stability.

2. The running time of the two mold bases is inconsistent (the difference is too large). If the material pipe flows downward at a constant speed, when the time difference between the left and right mold bases is large, the weight on both sides will be unstable. The faster the die frame is, the heavier the weight, and the slower the die frame is, the lighter the weight is due to stretching. The solution is to adjust the mold base on both sides to make the running time close.

3. The amount of extrusion is unstable. In case of unstable speed due to the running speed of the motor and unsuitable lightness of the belt, the amount of extrusion is unstable.

4. The reason for the plastic raw materials is different due to the different plastic raw materials or the mixing ratio changes, the output is different.

Adjusting method of bottle blow molding machine speed

Slow down the speed by increasing the exhaust time and increasing the saturation time, and at the same time reduce the overall temperature of the lamp box, the overall need to reduce the temperature of the lamp box by 1% for each increase of 0.1S. Increasing the speed is the opposite of reducing the speed.

(The exhaust time is as low as 0.8S, and if it is lower than 0.8S, there will be a bottle skipping phenomenon caused by the exhaust is not timely.) No matter the speed is increased or decreased, it should not be too fast. Quality, adjust the speed after the bottle is stable. Every time you adjust the speed, you must carefully observe the quality of the bottle and adjust the temperature of the light box at any time.

Both the bottle blowing cycle changes by 0.1S, the bottle output per hour changes by about 50, the bottle blowing machine should adjust the bottle blowing speed according to the speed of the filling machine.
