Film stretching machine with length adjusting mechanism

Abstract

The invention relates to the technical field of film stretching machines, in particular to a film stretching machine with a length adjusting mechanism. The film stretching machine comprises an inserting rail, an inserting groove is transversely formed in the left side of the inserting rail, a side beam is slidably inserted into the inserting groove, racks are fixedly mounted on the front inner wall and the rear inner wall of the left side of the inserting groove, a hydraulic cylinder connected with a clamping block is arranged in the middle of an inner cavity of an extending frame, a plurality of sets of fixing devices distributed linearly are arranged in inner cavity of the side beam, and each fixing device is composed of an extrusion block installed in a telescopic mode and an extrusion screw rod vertically connected in an inserted mode. The film stretching machine has the beneficial effects that by arranging inserting connecting of the inserting rail and the side beam, the stretching length can be adjusted, with the cooperation of the linear-distributed fixing devices, the film stretching machine is adaptive to stretching of films with different length requirements, the application range of the film stretching machine is greatly widened, and meanwhile the stability of the stretching process is enhanced.

Description

technical field [0001] The invention relates to the technical field of film stretching machines, in particular to a film stretching machine with a length adjustment mechanism. Background technique [0002] The film stretching machine is used to realize the stretching of the film piece, so as to realize the extension of the film length and obtain better performance. [0003] During the film stretching process, due to the different lengths of the film, the existing film stretching machine cannot adapt to the stretching length of the film, which greatly reduces the scope and adaptability of the film stretching machine. The telescopically installed film stretching machine has a complex telescopic structure and poor fastening stability, which cannot achieve the purpose of quick installation and convenient length adjustment. [0004] Therefore, a film stretching machine with a length adjustment mechanism is provided to solve the problem of length adjustment and adaptation of the ...
