Film blowing machine is widely used in industry, now introduce its working principle.

The film blowing machine is the most common plastic packaging machine. Its working principle is to simply absorb polyethylene, PVC, PE and other plastic particles into the machine's raw material hopper. The plastic particles enter the screw nest from the raw material hopper due to their own gravity.

When the raw material particles touch the oblique angle of the spiral, the rotating screw and the raw material particles will have a relative thrust, which will shift the plastic particles forward. During the displacement process, due to the conflict between the plastic and the screw, the plastic and the barrel The collision and friction between the two, plus the gradual melting due to the external heating of the barrel.

The molten plastic is filtered out by the machine head to remove impurities and come out of the die head die mouth, cooled by the wind ring, inflated by the herringbone plate, the traction roller, and wound to wind the finished film into a tube.

Film blowing machine is a mechanical device that melts plastic particles with bai and then blows them into a film.
