Hollow waste discharging device and waste discharging method of VHB (Very High Bond) rubber compound

Abstract

The invention provides a hollow waste discharging device and waste discharging method of a VHB (Very High Bond) rubber compound. The hollow waste discharging device comprises a first die-cutting mould, a second die-cutting mould, a composite mould and an adhering machine, wherein a structure of the second die-cutting mould is identical to that of the first die-cutting mould; and the cross sectionarea of a die-cutting cutter of the first die-cutting mould is less than that of a die-cutting cutter of the second die-cutting mould. According to the hollow waste discharging device and waste discharging method of the VHB rubber compound disclosed by the invention, a separate film is cut by utilizing the second die-cutting mould with the die-cutting cutter having the smaller cross section area,hollow waste discharging holes are cut out on the separate film, a VHB rubber compound tape adhered with the separate film is cut, and scraps of the VHB rubber compound tape is removed from the hollowwaste discharging holes by utilizing the adhering machine in an adhering manner, so that clean adhesion removal on the scraps can be ensured, and the phenomenon that a cutting outline of the VHB rubber cannot be extruded by the scraps also can be ensured so as to further ensure that occurrence of unqualified products can be avoided; and therefore, the production quality is ensured, manpower and material resources also can be reduced, and the production cost is controlled.

Description

technical field [0001] The invention relates to the field of die cutting, in particular to a VHB glue hollow waste discharge device and a waste discharge method. Background technique [0002] In the die-cutting industry, VHB rubber tape is a commonly used die-cutting raw material; VHB rubber tape is made of adhesive, foam layer and adhesive bonded sequentially from top to bottom, because VHB rubber The base material (foam layer) of the belt is very weak, so it is easy to deform under force. [0003] The traditional die-cutting mold is driven by a computer-controlled driving device to drive the die-cutter set on the upper template to move down, and after the tape is cut, the die-cutter on the upper template is driven to move up; use the traditional die-cutting mold to cut VHB rubber When belting, firstly, the release film and the VHB rubber belt need to be transported into the first feed port and the second feed port of the composite mould, and then the release film of the c...

Problems solved by technology

[0004] However, due to the low strength of the foam layer of the VHB rubber tape, when using a laminating machine to stick the waste, the waste is easy to stick to the edge of the cutting contour or squeeze the edge of the cutting contour. If it is judged as unqualified products because it is completely excluded or the cutting contour is deformed, it not only wastes manpower and material resources, but also increases production costs.
