What should I know about a film blowing machine

As a film blowing machine, due to the inherent characteristics of its product technology, plastic film blowing machinery basically operates non-stop 24 hours a day. Full load operation of the film blowing equipment causes significant damage to the body. If the film blowing machine is not maintained and serviced in a timely manner, it will have an impact on the service life of the machine, the accuracy and quality of film products. So, as a blown film machine operator, how should I do a good job of maintenance and upkeep? Electrical maintenance: Ensure the stability and reliability of the power supply, and ensure that the performance parameters meet the requirements; Maintain appropriate temperature and humidity, maintain good grounding, and pay attention to eliminating static electricity hazards; Dalian Blowing Film Unit

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

The main structure of the film blowing machine is composed of an extruder, a machine head, a mold head, a cooling device, a stable foam frame, a herringbone plate, a traction roller, a coiling device, etc. 1: The extruder is mainly composed of a screw, a barrel feeding hopper, a deceleration and driving motor, and the driving motor uses an electromagnetic speed regulation motor (or a frequency conversion ordinary motor). The reducer is driven by a belt drive to rotate the screw in the barrel; The plastic particles melted in the hopper under external heating are filtered through a three-way filter and squeezed from the mold mouth of the mold head. 2. The three-way filter is composed of a filter screen, a filter plate, and a three-way pressure cover. 3. The mold head is 4. The cooling device is composed of a cooling air ring, an air duct, a blower, etc. 5. The traction is composed of main components such as a traction frame, a herringbone plate, a traction roller, a winding mechanism, and a traction motor. 6. The electrical control part is generally equipped with a unit operation cabinet, Press the main button to turn on the main power supply, turn on the main switch of the motor, and control the heating of the body, three-way valve, and mouth mold buttons through the separate button switch,
