Description

Technical Field

[0001] The utility model relates to the field of PE film processing, in particular to a film cutting device used 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. PE protective film is based on special polyethylene (PE) plastic film and is divided into high-density polyethylene protective film, medium-density polyethylene and low-density polyethylene according to different densities.

[0003] When processing PE protective film, it is necessary to use a hot cutter to cut the long PE protective film into sections of PE protective sheets. However, when cutting the PE protective film, since the PE protective film itself has elasticity and toughness, if the hot cutter has no fulcrum during cutting, it is easy to connect with the PE protective film and it is not easy to cut the PE protective film.

[0004] Therefore, it is necessary to propose a film cutting device for PE protective film processing to solve the above problems. Utility Model Content

[0012] Technical effects and advantages of the utility model:

[0013] 1. Place the PE film to be cut on the sliding block position on the top of the cutting panel. Start the vacuum pump to make the adsorption groove generate suction. The adsorption groove can adsorb the lower surface of the PE film to create a connection between the sliding block and the PE film to prevent the PE film from moving.

[0014] 2. When the trapezoidal slider completely passes through the lifting and pressing plate, the lifting and pressing plate loses its driving force and automatically descends to press the upper surface of the PE film. The PE film can be cut by using a cutter through the cutting groove. Due to the pressing effect of the lifting and pressing plate on the PE film and the adsorption of the sliding block at the bottom of the PE film, the pulling force generated can tighten the PE film so that the cutting will not produce sticking. At the same time, through the movement of the sliding block, the PE film can be automatically moved forward, reducing the manual pulling of the PE film for cutting. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The PE film 10 to be cut is placed on the position of the sliding block 11 on the top of the cutting panel 1, and the vacuum pump 13 is started to make the adsorption groove 12 generate suction. The adsorption groove 12 can adsorb the lower surface of the PE film 10 to create a connection between the sliding block 11 and the PE film 10.
