Description
Technical Field
[0001] The utility model relates to the technical field of exhaust devices, and more specifically to a film blowing exhaust device for a film blowing machine. Background Art
[0002] The film blowing machine is a device that heats and melts plastic particles and then blows them into thin films. During the processing, dry polyethylene particles are added to the lower hopper, and the particles enter the screw from the hopper by their own weight. When the particles come into contact with the beveled edges of the threads, the rotating beveled edges generate a thrust perpendicular to the beveled edges on the plastic, pushing the plastic particles forward. During the pushing process, due to the friction between the plastic and the screw, the plastic and the barrel, and the friction between the particles, and also due to the external heating of the barrel, the plastic gradually melts; the molten plastic is filtered through the machine head to remove impurities and comes out from the die head die, cooled by the air ring, inflated, and rolled into a tube through the herringbone plate, traction roller, and winding. The film blowing exhaust device is needed in the exhaust process of the film blowing machine, but due to the long-term use of the existing exhaust device, more impurities will remain on the dustproof net. If it is not replaced in time, it is easy to reduce its filtering efficiency, which is not conducive to its use. For this reason, a film blowing exhaust device for a film blowing machine is provided.
