Problems solved by technology

[0003] In the prior art, when trimming the raw edges, the film needs to be flattened and conveyed first, and then the edge is trimmed with a cutter. However, when the film is flattened by the machine, the edge tends to roll upwards. The film at the place cannot be trimmed smoothly, which leads to the presence of burrs

Abstract

The invention relates to the technical field of film edge cutting, and discloses an edge cutting device for CPP film rolling. The edge cutting device comprises a base, an edge cutting frame, a first pressing roller, a second pressing roller, a first side plate, a second side plate and first fixing plates. The edge cutting frame is fixed to the upper surface of the left portion of the right end of the base, the edge of the edge cutting frame is parallel to the side edge of the base, a sliding groove is formed in the upper surface of the left side of the edge cutting frame and communicates with the interior and the exterior of the edge cutting frame, adjusting rods vertically penetrate through the left side and the right side of the interior of the sliding groove, and upper pressing pieces are fixedly welded to the tops of the adjusting rods. According to the edge cutting device for CPP film rolling, the first side plate and the second side plate are arranged on the surface of the edge of the base of the first pressing roller and the surface of the edge of the base of the second pressing roller, rotating rods driven by servo motors to rotate and soft brushes are arranged in the first side plate and the second side plate, an upper turnup roll on the edge of a film in the conveying process can be pulled down and flattened, then burrs can be smoothly cut off conveniently. and meanwhile, the distance adjusting range of cutters is larger, so that the device is suitable for films with more sizes.

Description

technical field [0001] The invention relates to the technical field of film edge trimming, in particular to an edge trimming device for winding a CPP film. Background technique [0002] At present, the CPP film is a cast polypropylene film, which is a polypropylene film produced by a cast extrusion process in the plastics industry. The CPP film only has a certain orientation in the longitudinal direction, mainly due to the nature of the process. Rapid cooling on the top of the film forms excellent clarity and smoothness on the film. At present, there are burrs in the film during the winding process of the CPP film. Before winding, the film needs to be trimmed to ensure the overall quality of the film and normal winding. Work. [0003] In the prior art, when trimming the raw edges, the film needs to be flattened and conveyed first, and then the edge is trimmed with a cutter. However, when the film is flattened by the machine, the edge tends to roll upwards. The film at the ...
