How to do a good job in maintenance and upkeep of the blowing film unit

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. How to do a good job in maintenance and upkeep of the blowing film unit?

All layers of the co extruded film are extruded together at the same time, so there will be no other non plastic materials such as aluminum foil and paper. The combination form of its product materials is relatively limited, and its applicability is also limited. However, due to the hot melt bonding between layers without the need for adhesives, the hygiene and safety of food packaging co extruded films are relatively reliable.

Thin films produced by blending single-layer LDPE or LDPE with other resins have single properties and cannot meet the packaging requirements of modern product development. Therefore, co extruded films produced by co extrusion blown film or co extrusion casting equipment have improved overall performance. The comprehensive performance of membranes, such as mechanical strength, heat sealing performance, heat sealing temperature, barrier properties, opening properties, and pollution resistance, has been improved, while their processing costs have been reduced, making them widely used. When starting the main motor, the motor should be started first and then slowly accelerated until it reaches the required speed and stabilizes; If the machine is shut down for maintenance, it should be slowed down first before shutting down;

When preheating the three-layer co extrusion blown film machine, the heating should not be too long or too high to avoid blockage of the material outlet; Those who have the conditions can use an automatic temperature control system to set up upper and lower tolerances for automatic stability, convenience, and safety; After the host is turned on, pay close attention to the operation of the host, adjust, correct, electrical instruments, and controllers in a timely manner, observe for abnormalities or damage, and repair and replace them to ensure their normal operation;
