Laminar film pasting machine

Abstract

The invention provides a laminar film pasting machine. The laminar film pasting machine comprises a supporting mechanism, a laminar film disc mounted on the supporting mechanism, and a loading mechanism mounted on the supporting mechanism and loaded with a laminar film from the laminar film disc and further comprises a bottom film body tearing mechanism. The bottom film body tearing mechanism comprises two clamping mechanisms for clamping a bottom film body of the laminar film, two twisting mechanisms corresponding to the clamping mechanisms, and a first moving mechanism. The clamping mechanisms each comprise a clamping jaw and an opening-closing mechanism for controlling clamping and loosening of the clamping jaw and are mounted on the corresponding twisting mechanisms. The twisting mechanisms are mounted on the first moving mechanism and can twist the clamping mechanisms to a preset angle clockwise when the clamping jaws clamp the bottom film body of the laminar film. After the twisting mechanisms twist the clamping mechanisms to the preset angle, the first moving mechanism can move the twisting mechanisms to the positions where the bottom film body of laminar film and a pastingfilm body of the laminar film are completely separated. The laminar film pasting machine can replace manual work to strip the bottom film body of the laminar film automatically, thus the production efficiency is promoted greatly, and the working intensity of workers is reduced.

Description

technical field [0001] The application relates to a film laminating machine, in particular to a sheet film laminating machine. Background technique [0002] The film (label) machine of the prior art has the same core parts, that is, the incoming materials are roll materials, and the principle of label stripping is the same. The rigidity and elasticity of the label itself is greater than the adhesion between the label and the label backing paper. The label backing paper implements a sharp turn at a large angle (generally close to 180°), forcing the label to separate from the label backing paper, so as to achieve the purpose of "stripping off the label". The roll material has its own defects. There is a left-right position deviation when rewinding, and there is another left-right position deviation when the labeling machine is unwinding. The curvature of the outer and middle labels is different, and air bubbles often occur when laminating. In some high-demand areas, the incom...

Problems solved by technology

[0003] Although the sheet material itself has a high degree of consistency, there is no special machine for automatic production in the process of use. The current coiling machine cannot be used at all, and most of them can only be manually stripped.

When manually peeling off the backing paper (film), hands often touch the sticker on the back, which will affect the adhesive force of the sticker. Manual pasting cannot achieve accurate alignment, and there are differences between pastings. The waste of materials is large. In addition, the operator concentrates on close-up vision for a long time, which will cause great damage to eyesight. This work will cause a high probability of occupational injury
