High-precision film cutting device for film production

Abstract

The invention discloses a high-precision film cutting device for film production. The device comprises a cutting mechanism, a buffer mechanism and an edge pressing mechanism; when the cutting mechanism is used for cutting films in an up-down reciprocating manner, the cutting mechanism drives the buffer mechanism to downwards press the films to form buffer sections; when the cutting mechanism cuts the films, the buffer mechanism can be quickly ascended along with descending of the cutting mechanism without needing the films to bear the weight thereof; and meanwhile, the edge pressing mechanism can press two side edges of the films for fixation, so that the cutting mechanism can accurately and quickly cut the films, the technical problem of pull deformation of the films in the cutting process due to punching force and tension is solved, and the functions of film buffering and automatic cutting positioning are realized.

Description

[0001] machine technology [0002] The invention relates to the technical field of film cutting, in particular to a high-precision film cutting device for film production. Background technique [0003] After the film is shaped and rolled, it is necessary to re-cut the rolled film to obtain a film of the required size for composite use. During the cutting process, the film is cut on the cutting machine with the same frequency and intermittent twitching, section by section. Cut into finished film, and in the cutting process, due to the strong plasticity of the film, if the film is in a tight state, it is easy to pull the film and partially deform it due to the punching force and tension during the cutting process. , affecting the use of later films. [0004] In the Chinese patent with the patent number CN105966962A, a film cutting machine is disclosed. By setting a buffer device between the guide rollers, the film forms a buffer at one end during the cutting process to prevent ...

AI Technical Summary

Problems solved by technology

[0005] In view of the above problems, the present invention provides a high-precision film cutting device for film production. When the film is reciprocated up and down by the cutting mechanism, the buffer mechanism is driven by the cutting mechanism to press down the film to form a section. The buffer section, and when the cutting mechanism cuts the film, the buffer mechanism will rise rapidly with the lowering of the cutting mechanism, without the need for the film to bear its weight, and at the same time, the edge-holding mechanism will press the two sides of the film to fix it , so that the cutting mechanism can accurately and quickly cut the film, which solves the technical problem of the film being deformed by punching pressure and tension during the cutting process, and realizes the function of film buffering and automatic positioning of cutting
