Collision friction of three-layer co-extrusion film blower

Which is the best three-layer co-extrusion film blower? Film blower is a device which melts and blows plastic particles into thin film by heating. There are many kinds of film blowers, such as PE, POF, PVC, etc. The new material is blown out by new plastic particles in the film blower. The color is symmetrical, clean and the bag is well stretched. Dry polyethylene particles are added to the hopper during the production process and principle.

The three-layer co-extrusion film blower enters the screw from the hopper by the weight of the particles. When the particles come into contact with the screw bevel, the rotating bevel faces the plastic and generates a thrust perpendicular to the bevel. The plastic particles are pushed forward. During the pushing process, due to the friction between the plastic and the screw, between the plastic and the barrel, and the collision and friction between the particles.

At the same time, it gradually melts due to heating outside the barrel. Traction, composed of tractor frame, herringbone, towing roll, coiling mechanism and traction motor, is an electrical control part. Generally, the unit is equipped with unit operating cabinet. The general power supply is switched on by the general button and the general switch of the motor is opened. The body and tees can be controlled by the button switch and the electric heating of each button of the moulds can be controlled separately.

The key part of the two coils is thermocouple automatic temperature measurement and control. During normal production process, temperature can be controlled automatically to ensure stable and reliable production process. The size of the membrane opening is related to the gap, and also to the air pressure of the film blower. The larger the bubble, the wider the membrane opening and the larger the blowing film.
