Abstract

The utility model relates to a film tearing mechanism which comprises a substrate, wherein a positioning groove is formed in the substrate, film tearing workpieces and clamping assemblies are respectively arranged on two sides of the substrate, a sucker is arranged in the positioning groove, and the film tearing mechanism further comprises a moving assembly for driving the substrate to move so that the film tearing workpieces are close to or far away from a film tearing position. The film tearing mechanism is ingenious in design, a film tearing workpiece is driven to be close to a film tearing position through a moving assembly, the film tearing workpiece is inserted into the end portion of the double faced adhesive tape on the film tearing position to separate the waste film from the adhesive layer, the separated waste film is sucked into a positioning groove through matching of a sucker and the film tearing workpiece, and after the waste film is clamped and fixed in the positioning groove through a clamping assembly, the moving assembly pulls a substrate and the film tearing workpiece to be far away from the film tearing position to tear the waste film. The mode that this kind of adoption non-contact absorption and clamping assembly cooperation were peeled off and are combined avoids the glue face fish tail and the problem of fingerprint pollution that manual operation led to, and this mechanism degree of automation is high, and the waste film can be separated from the material fast, need not manual intervention, tears the membrane efficient.

Description

Dyestripping mechanism Technical Field The utility model relates to a film tearing mechanism. Background In the process of carton packaging production, the double-sided tape is widely applied to links such as box body adhesion, sealing and reinforcement. In order to protect the tackiness of the adhesive surface, the surface of the double-sided adhesive is usually covered with a release film or a protective film, and the release film or the protective film needs to be precisely torn off before the lamination process. Currently, the film tearing operation is mainly finished manually, and an operator needs to pick up the edge of the film material with fingers or a simple tool (such as a blade) and peel the edge. However, this approach has the following prominent problems: 1.
