Description

Technical Field

[0001] The utility model relates to the technical field of PE protective film processing, and more specifically to a hot cutting device for PE protective film processing. Background Art

[0002] PE protective film is the simplest macromolecular organic compound and the most widely used macromolecular material in the world today. It is mostly used to protect products from pollution and scratches during production, processing, transportation, storage and use, and to protect the original smooth and shiny surface, thereby improving product quality and market competitiveness. In the production process of PE film, it is often necessary to cut the PE film into a certain width for practical application.

[0003] After searching, a hot cutting device for PE protective film processing disclosed in publication number CN216072417U includes a base, a cutting workbench, a PE film unwinding mechanism, a protective film limiting device, a hot cutting mechanism and a film pressing mechanism. The PE film unwinding mechanism is arranged on one side of the base, the cutting workbench is embedded in the middle position of the base, the hot cutting mechanism is arranged on the cutting workbench, the film pressing mechanism is arranged on the base and is located above the cutting workbench, and the protective film limiting device is installed on the base and is located between the PE film unwinding device and the hot cutting mechanism.

[0004] The above-mentioned technical solution has certain beneficial effects, but in actual use, the PE film will be pressed downward by the film pressing mechanism, and the roller at the bottom will roll on the surface of the PE film, so that the PE film and the hot cutting mechanism will contact each other. However, in this process, one end of the PE film will be pressed downward first, and the PE film will be in a state of being pulled downward, so that tension will be generated between the cut position and the uncut position, which will cause the PE film to be pulled and deformed, reducing the hot cutting effect of the PE film. For this reason, we propose a hot cutting device for PE protective film processing. Utility Model Content
