Technical Field

[0001] The utility model relates to a dustproof device, in particular to a dustproof device for producing frosted films. Background Art

[0002] In the process of producing frosted film, a film blowing machine is used. The film blowing machine puts the raw material particles into the lower hopper, and the raw material enters the screw from the hopper. When the raw material contacts the bevel of the screw thread, the rotating bevel pushes the raw material particles forward. During the pushing process, the raw material gradually melts due to the heat generated by extrusion friction and external heating. The molten raw material is extruded from the die head, blown, cooled by the air ring, pulled by the traction frame, pulled by the traction roller, and then rolled up by the winding frame into a film tube.

[0003] After the film blowing machine blows out the frosted film, the frosted film is exposed to the external space. If there is dust in the internal environment of the frosted film production workshop, the frosted film blown out by the film blowing machine will be easily contaminated by the dust, thereby affecting the quality of the frosted film and being unfavorable for the use of the frosted film. Based on the above reasons, the utility model proposes a dustproof device for frosted film production. Summary of the invention
