Inspection and maintenance of plastic film blowing machine before starting up

Startup inspection and maintenance of plastic film blowing machine
A plastic film blowing machine heats and melts plastic particles before blowing them into a thin film. There are many types of plastic blow molding machines, including PE, POF, and so on. Next, let me talk about the inspection and maintenance of plastic blow molding machines before starting up.
1. The temperature control of the plastic film blowing machine is intact, and the heating appliances are intact. Pay attention to adjusting the heating temperature at each point in a timely manner within the specified range.
2. Check the traction speed and control the thickness of the film.
3. Observe and adjust the uniformity of the film thickness, and ensure that the bending diameter meets the standard.
4. Check the pressure of the air storage cylinder. The plastic film blowing machine should not be too high, but there should be a backup pressure.
5. Check and control the raw material ratio and mix evenly.
6. Check for impurities in the raw materials, especially by promptly using a magnet to check for iron mixing.
7. Check the gearbox position of the plastic film blowing machine and the lubrication of the air compressor cylinder lubricating oil.
8. Regularly check the temperature rise and mechanical transmission of each operating motor.
