A film blower is a device that melts plastic particles and then blows them into a film. There are many kinds of film blowing machine, PE, POF, PVC, etc. The film blowing machine uses new plastic particles to blow out new material, whose color and color are all said, clean, and the bag is stretched well. The production process and production principle are to add dry polyethylene particles into the hopper, and the three-layer co-extruded film blowing machine enters the screw from the hopper by the weight of particles themselves. The rotating helical face of the plastic produces a thrust perpendicular to the helical face.
The plastic particles are moved forward. In the process of moving, due to the friction between the plastic and the screw, the plastic and the barrel, as well as the collision friction between the particles, it is also gradually dissolved due to the external heating of the barrel. Traction by traction frame, miter plate, traction roller, winding machine and traction motor and other main components, electrical control part, the general unit is equipped with unit operating cabinet, by the main button to press the main power supply, open the main motor switch, can respectively control the fuselage and three through the button switch, the mouth die each button electric heating.
The key part of the two groups of coils using thermocouple automatic temperature measurement and automatic temperature control, normal production process, the temperature can be automatically controlled, to ensure the production process is stable and reliable, the size and gap of the membrane mouth is related, and the pressure of the film blowing machine is related to the greater the pressure the bigger the bubble the wider, the larger the membrane mouth, the larger the blowing film.
