Description

Technical Field

[0001] This utility model relates to the technical field of protective film processing equipment, specifically a protective film anti-fouling slitting and die-cutting device. Background Technology

[0002] According to the patent authorization announcement number CN211615857U, a protective film anti-fouling slitting die-cutting device is disclosed. This utility model relates to the technical field of protective film processing equipment. Its key technical points are: it includes a main body, which is equipped with a fixed base and a support frame. An adhesive roller group is mounted on the support frame. A protective film roller and a first PE film roller are mounted on the front side of the adhesive roller group. A protective film is wound on the protective film roller, and a first PE film is wound on the first PE film roller. A slitting die-cutting roller group is mounted on the rear side of the adhesive roller group. A recycling roller group is provided at the rear of the assembly. The protective film and the first PE film are respectively conveyed to the bonding roller group via the protective film roller and the first PE film roller. After passing through the bonding roller group, the protective film and the first PE film are bonded to form a multi-layer protective film, which is then conveyed to the slitting and die-cutting roller group. The multi-layer protective film is slitting and die-cut into multi-slice protective films by the slitting and die-cutting roller group. Each slice of protective film is recycled by the recycling roller group. This utility model improves the yield of slitting protective films by laminating a PE film on the surface of the protective film. During the slitting and die-cutting process of the protective film, dust falls onto the PE film and does not cause dirt to the protective film.

[0003] However, there are problems with the existing technology: as a core processing component, the slitting die-cutting cutter roller bears the important mission of precision cutting. However, with long-term and high-frequency operation, various kinds of residues inevitably adhere to the surface of the cutter roller. The generation of these residues mainly comes from the residual debris of the processed material during the cutting process, the adhesion of hot melt materials after cooling, and the adhesion of dust and impurities in the production environment. Over time, the residues accumulate and form a raised or uneven layer on the surface of the cutter roller, thereby changing the original contour accuracy of the cutter roller. When this surface condition deteriorates to a certain extent, it will seriously interfere with the normal cutting operation, resulting in insufficient cutting depth, uneven cutting edges, and other incomplete cutting. This not only affects the processing quality of the product but also reduces production efficiency. Utility Model Content
