Film splitting machine

Abstract

The invention relates to the field of film cutting, in particular to a film splitting machine which comprises an unwinding mechanism, a stripping mechanism, a slitting mechanism, a winding mechanism and a stripping and winding mechanism, a film is wound on the unwinding mechanism, a supporting device used for supporting the film is arranged on the unwinding mechanism, and after the film is pulled, stripping of an adhesive film and a non-adhesive film is conducted on the stripping mechanism. Then the adhesive film is subjected to splitting treatment at the slitting mechanism, the adhesive film is split into strip-shaped films with the required width, the split strip-shaped films are pulled by the winding mechanism and is subjected to winding treatment at the winding mechanism, the winding mechanism comprises two winding rollers, and the non-adhesive film is pulled by the stripping and winding mechanism and is subjected to winding treatment at the stripping and winding mechanism. A limiting device is arranged on the stripping and winding mechanism. According to the film splitting machine, the situation that a viscous material adheres to a guide roller is avoided, the separated adhesive film is a bubble-free product, the limiting device prevents the release film from shaking in the winding process, and winding of the non-adhesive release film is facilitated.

Description

technical field [0001] The invention relates to the field of film cutting, in particular to a film cutting machine. Background technique [0002] In the manufacturing process of films, such as PET protective films, the films need to be peeled off, slit, and finally wound up. After the film is peeled off, sticky film and non-sticky film will be obtained. In the prior art, there are many guide rollers used for guiding the film slitting machine. After the peeled sticky film is wound around the guide roller, due to One side of the sticky film is sticky, and the material with the sticky side is easy to stick to the guide roller, so that the sticky film will stick and affect the product quality. At the same time, the material on the sticky side will make a sharp and harsh sound when passing the guide roller. The sticky film and the guide roller will also cause the slitting machine to vibrate, resulting in deviation and irregular winding. Therefore, it is necessary to improve the...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a film slitting machine. This technical solution solves the problem in the prior art that the sticky film is easily stuck to the guide roller and affects the quality of the product. The sticky film is directly wound to avoid stickiness. The material sticks to the guide roller, and the separated adhesive film is a product without air bubbles. The limit device prevents the release film from shaking during winding, which is convenient for the non-adhesive release film to be rolled.
