Precautions for plastic film blowing machine

1. Always develop a good habit of checking that the temperature automatic control is intact, the heating appliances are intact, and the heating temperature of each point is adjusted in time to be within the range of the index; if there is an abnormality, it must be resolved in time.
2. Check the traction speed and control the film thickness; ensure that there is no deviation in the production process and improve the quality as much as possible.
3. Observe whether the film thickness is uniform, whether the folding diameter meets the standard, and whether there is deviation in the width of the blown film; and make appropriate adjustments.
4. Check and control the pressure of the air storage cylinder. It should not be too high, but there should be a spare pressure.
5. Keep the raw material ratio and mix evenly, and reject the operation of unbalanced ratio; check the classification when producing pure raw materials, so as not to affect the quality of unevenness.
6. Check the raw materials for impurities. When metal foreign matter is mixed in, you should use a magnet to forcibly absorb the mixed material in time. If necessary, stop the machine for inspection and take it out as soon as possible to prevent damage to the machine and affect the operation.
7. Check the gearbox position and the lubrication of the air compressor cylinder lubricating oil, and ensure that the lubricating oil is sufficient when starting the operation.
8. Regularly check the temperature rise and mechanical transmission of each running motor. Suggestions for recording data. Recording the data can provide help for future operations.
Precautions for body maintenance
1. Since electrical components may be damaged during transportation or the wire ends may fall off, you should strictly check first. In order to ensure personal safety, you must connect the ground wire when opening the organ, then turn on the power supply, and then strictly check whether the motors are running correctly at all parts, and pay attention Whether there is leakage phenomenon.
2. When installing, pay attention to adjusting the center line of the extruder head and the center of the traction roller to keep it horizontal and vertical, and not to deviate from the skewed.
3. As the outer diameter of the winding gradually increases during winding, please pay attention to the coordination of the traction speed and the winding speed, and please adjust it in time.
4. After the host is turned on, pay close attention to the operation of the host, adjust, correct, electrical instruments, and controllers in time to observe whether there is any abnormality or damage, and repair and replace it to ensure its normal operation.
5. The main engine gear box and traction reduction box should be refueled frequently, and the gear oil should be replaced (the oil level is enough to reach the mark line). Please replace the new gear oil within about 10 days of use for the new machine to ensure the normal operation of all rotating parts and prevent operation Difficulties and overheating damage, the tightness of each connection part should also be checked to prevent the bolts from loosening.
6. The compressed air in the bubble tube should be balanced, because the compressed air will leak out during the towing process to achieve the effect of timely replenishment.
7. Frequently clean and replace the filter screen in the machine head to prevent clogging, and prevent the plastic particles from being mixed with iron, sand, stone and other impurities from falling into the barrel to avoid damage to the screw and barrel.
8. It is strictly forbidden to rotate without material. When the barrel, tee, and die have not reached the required temperature, the host cannot be started.
9. When starting the main motor, start the motor first and then slowly accelerate, and stabilize after reaching the required speed; when turning off the main motor, first decelerate and then shut down.
10. During preheating, the heating should not be too long or too high to avoid clogging of the material port; if possible, the automatic temperature control system can be used to set the upper and lower tolerance temperature automatically, which is convenient and safe.
Attention to the use of plastic film blowing machine
1. The operator cannot stand in front of the machine when operating the machine to avoid accidental injury to the operator. When feeding the film blowing machine, strictly prevent the hard objects that contain metal impurities and operating tools from falling into the barrel of the machine. It is forbidden to wear gloves when operating the rotating machine to prevent getting involved and injured.
2. Check and add the lubricating oil in the gearbox and air compressor, and check the lubrication of the mechanical transmission parts. Avoid dry operation damage the machine and make noise.
3. When the die outlet is uniform and uniform, you can wear gloves to slowly pull up the tube blank, and at the same time, close the end of the tube blank and slightly open the air inlet regulating valve to put a small amount of compressed air into the center hole of the mandrel. Carefully guide the foam stabilizer, herringbone plate, and pass through the traction roller and guide roller until it is taken up
4. Within the range of film forming conditions, increase the forming temperature, cooling air temperature and blow up ratio; then the turbidity of the film will increase and the gloss will decrease; vice versa.
5. When starting the operation, you must first check whether the power supply wiring is disconnected or leaking; check whether the instrument is damaged or not. Before starting the machine, ensure that all components are safe and normal to avoid affecting production and causing accidents.
6. The compressed air pressure of the inflated tube blank should be appropriate, not only can not break the tube blank, but also ensure the symmetry and stability of the membrane tube, and relatively ensure the quality of production. [1]
