The purpose of developing co extrusion blown film machines

Inspection and maintenance of the film blowing machine system
1. Feeding machine system: Clean the filter in a timely manner and check for air leakage in the negative pressure feeding system.
2. Extruder system:
① Observe the pressure gauge and main motor current, and clean the screen changer in a timely manner
② Check for noise and overheating in the gearbox, screws, and main motor
③ Check the operating frequency, current, and temperature rise of the frequency converter, and clean the motor and frequency converter dust on time.
④ Correct the measurement error between the thermocouple and the actual temperature.
⑤ Correct the placement of the extruder, adjust the groove wheels to ensure the placement angle and level of the extruder.
