Normal startup steps for blown film machine

Normal startup steps for blown film machine:
1. Heat the extruder body, head, die head, and control the temperature at each point within the specified range.
2. If driving after a long stop, the heating temperature at each point needs to be kept constant for 10-30 minutes after reaching the target range. If driving within half an hour of parking, constant temperature is not required.
3. Start the air compressor and stop for backup when the pressure in the storage cylinder is 6-8 kg/cm.
4. Based on the film bending diameter, thickness requirements, and extruder production capacity, estimate the traction speed and stable bubble diameter for processing.
5. After the temperature at each point meets the requirements, put on personal protective equipment and start the tractor, blower, and extruder in order.
6. When the discharge from the mold is uniform and consistent, gloves can be worn to slowly lift the tube blank. At the same time, the end of the tube blank should be closed, and the air inlet regulating valve should be slightly opened to blow a small amount of compressed air from the center hole of the core rod. Then, carefully guide it through the stable bubble holder and the herringbone plate, and insert it into the traction roller and guide roller until it is coiled.
7. Check the thickness and width of the film at all locations and adjust them to meet the requirements.
