Problems solved by technology

In order to improve the production efficiency of film-type materials, manufacturers have gradually adopted automatic processing equipment to automatically tear the film-type materials. However, flexible films are often not complete and non-porous flat films, and the middle part of the flexible film is cut out. In the conventional tearing film engineering, the use layer in the flexible film is easily torn and deformed due to the existence of the special-shaped holes, which will cause damage to the use layer in severe cases, and the pass rate of the tear film processing is low. It is difficult to For industrial mass production

Embodiment Construction

[0018] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the embodiments are not intended to limit the present invention.

[0019] Such as figure 1 and figure 2 As shown, a method for separating flexible film layers uses a tearing film assembly to press and paste the available film A1 and the waste film A2 in the flexible film to the air suction surfaces of the first vacuum plate 1 and the second vacuum plate 2 respectively. The component moves at a constant speed along the tearing film direction relative to the vacuum plate;

[0020] The film tearing assembly includes a first roll bar 3 against the first vacuum plate 1 and a second roll bar 4 and a third roll bar 5 against each other, and the usable film A1 starts from the second roll Pass between the pressing bar 4 and the third rolling bar 5 and then enter ...

Abstract

The invention relates to the technical field of separation of multilayer film materials and particularly relates to a layer separation method for a flexible film. According to the layer separation method for the flexible film, an available film and a waste film in the flexible film are separately stuck to an air suction surface of a first vacuum plate and an air suction surface of a second vacuum plate in a pressing manner by using a film tearing component, and the film tearing component moves along a film tearing direction at a constant speed relative to the vacuum plates; and the available film and the waste film in the flexible film are required to be separated firstly before using the flexible film, and the completely-stuck flexible film can be easily separated by a small section by using the principle that the deformation quantity between the available film and the waste film is different by adopting the layer separation method for the flexible film, disclosed by the invention, so that primary-stage preparation for film tearing by subsequent automated film tearing equipment is completed, artificial participation is not required, the labor cost of a film tearing procedure is greatly reduced, the automated film tearing efficiency is greatly increased, the progress is obvious, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of separation of multilayer membrane materials, in particular to a method for separating flexible membrane layers. Background technique [0002] Membrane materials need to be bonded and protected with auxiliary layer structures such as release paper after production, so as to facilitate the storage and transportation of available films. In actual use, the auxiliary layer structure needs to be removed before it can be applied to actual production and production. Processing. In order to improve the production efficiency of film-type materials, manufacturers have gradually adopted automatic processing equipment to automatically tear the film-type materials. However, flexible films are often not complete and non-porous flat films, and the middle part of the flexible film is cut out. In the conventional tearing film engineering, the use layer in the flexible film is easily torn and deformed due to the existence ...
