Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of film blowing machines, in particular to a film blowing machine with a screening and crushing mechanism. Background Art
[0002] The film blowing machine heats and melts plastic particles and then blows them into thin films. There are many types of film blowing machines, including PE, POF, PVC, etc. The new materials blown out by the new particles are new materials with uniform color, clean, and good bag stretching. The basic working process of the film blowing machine is to add dry polyethylene particles into the lower hopper, and the particles enter the screw from the hopper by their own weight. When the particles come into contact with the bevel of the thread, the rotating bevel surface produces a thrust perpendicular to the bevel surface on the plastic, pushing the plastic particles forward. During the pushing process, the friction between the plastic and the screw, the plastic and the barrel, and the collision and friction between the particles, as well as the external heating of the barrel gradually melt. The molten plastic is filtered through the machine head to remove impurities and comes out from the die head. It is cooled by the air ring, blown up, and rolled into a tube through the herringbone plate, traction roller, and winding.
[0003] However, the existing film blowing machines cannot crush the added raw materials. If the added raw material particles are large, the melting speed will be slow, and the feed port of the film blowing machine is prone to accumulation of raw materials, causing blockage. Therefore, a film blowing machine with a screening and crushing mechanism is needed to solve the above problems. Utility Model Content
