Description

Technical Field

[0001] The utility model relates to the technical field of film blowing machines, in particular to a hopper device for a film blowing machine and a film blowing machine. 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 brand new particles are new materials with uniform color, clean and good bag stretching. The principle is to add dry polyethylene particles into the lower hopper, and rely on the weight of the particles themselves to enter the screw from the hopper. 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 melts. The molten plastic is filtered through the die head to remove impurities and comes out from the die head. It is cooled by the air ring, blown up, and passed through the herringbone plate, traction roller, and coiled to roll the finished film into a tube.

[0003] The existing film blowing machine hopper device can only discharge plastic particles but cannot filter the plastic particles. Since there are some larger particles in the plastic particles, these larger particles enter the film blowing machine without being filtered, causing blockage in the internal channels of the film blowing machine and even incomplete melting of the plastic particles, resulting in poor quality of the blown film, which seriously affects the film blowing effect of the film blowing machine.

[0004] To this end, we propose a hopper device for a film blowing machine and a film blowing machine. Utility Model Content
