Abstract

The invention discloses a flat-knife feeding system with ultra-thick double-sided adhesive, no overflow glue and no knife marks, which is characterized in that it includes the following processes: S1, round knife slitting; S2, laminating; S3, A-die stamping ; S4, B die stamping; S5, C die stamping; S6, D die stamping; S7, E die stamping; S8, F die stamping. The invention realizes the cutting of the release film in different processes through ABCDEF, that is, the cutting process uses horizontal and vertical splicing to cut the tape, and adopts the method of digging waste to retain the product to meet the dimensional accuracy of the product. This method not only solves the problem of double-sided adhesive tape The problem of glue overflow on the glue surface is difficult, and the technical problem of no knife marks on the upper and lower bottom films is solved at the same time, which increases the peeling effect of the product. Through the material feeding system, the waste material is pulled out while feeding, ensuring the continuity of production at each stage.

Description

technical field [0001] The invention relates to the technical field of double-sided adhesive tapes, in particular to an ultra-thick double-sided adhesive tape without spillage and without knife marks and a flat knife feeding system. Background technique [0002] At present, the thickness of double-sided tape on the market is more than 0.05MM, and there is generally a slight overflow of glue. If the thickness exceeds 0.1MM, the glue overflows seriously. If the thickness exceeds 0.15MM, it is difficult to process, and the bottom film will have a knife during the processing of the existing technology. print. For this reason, we have designed a super-thick double-sided adhesive tape-free process and a flat-knife feeding system. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to solve the problems existing in the prior art, and proposes an ultra-thick double-sided adhesive tape with no spillage and no knife marks and a flat knife feeding system. [0...
