PE film blowing device

Abstract

The invention discloses a PE film blowing device. The PE film blowing device comprises a box and an extruder. A feeding hopper is arranged at the left portion of the top end of the extruder. A film blowing machine is arranged at the right end of the extruder, and a film outlet is formed in the top end of the film blowing machine. A first limiting rod is in sliding connection between the left sidewall and the right side wall in the box, and a second limiting rod is in sliding connection between the front side wall and the rear side wall in the box. A fixing base is arranged at the bottom end of the box. The PE film blowing device is reasonable in structure design. According to the film blowing device, on blown-out film diameter adjustment, and a transmission structure is improved for automatic adjustment; during adjustment, it can be guaranteed that the center of a film is located over a film discharging machine all the time, convenience is achieved, an original adjusting manner is replaced, the work efficiency is improved, and the climbing danger is avoided; and when the film discharging diameter is adjusted, guiding plates are adjusted at the same time, through the arrangement offew adjusting devices, the adjusting effect is improved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a film blowing device, in particular to a film blowing device for PE films. Background technique [0002] PE protective film is the most widely used polymer material in the world today. The PE protective film is based on a special polyethylene (PE) plastic film. The biggest advantage of the PE protective film is that the protected product will not be polluted, corroded, scratched, and protect the original product during production, processing, transportation, storage and use. The smooth and shiny surface can improve product quality and market competitiveness. In the production of PE film, a film blowing device is required. [0003] Existing film blowing devices generally use manual adjustment of the diameter of the blown film to adjust the diameter of the blown film. When adjusting, it is necessary to mount the adjustment box, which is very troublesome and dangerous; after adjusting the diameter of the film, it is also necessa...

Problems solved by technology

[0003] Existing film blowing devices generally use manual adjustment of the diameter of the blown film to adjust the diameter of the blown film. When adjusting, it is necessary to mount the adjustment box, which is very troublesome and dangerous; after adjusting the diameter of the film, it is also necessary to adjust the guide plate. Adjustment, but the adjustment of the folded plate is separated from the adjustment device of the film diameter. It is not easy to control the adjustment amount during adjustment, which reduces the efficiency of adjustment and affects production efficiency.
