A tooth edge double-sided adhesive tape and its preparation device and method

Abstract

The present invention proposes a double-sided tape with tooth edges and its preparation device and method. The double-sided tape with tooth edges includes a release paper and a cotton glue layer. The side of the paper is formed with a tooth edge peeling structure, and the cotton glue layer on the tooth edge peeling structure is removed. The preparation device is based on the tooth edge peeling structure. The cutter structure of the abrasive blade is innovatively set. With the help of thick line knife and thin line The ingenious cooperation of the knife realizes the cutting of the tooth edge and the stripping area of ​​cotton glue. The invention realizes the purpose of quickly peeling off the release paper of the double-sided adhesive at any position by setting a tooth-edge peeling structure for removing the cotton glue layer on the side along the length direction of the double-sided adhesive, and improves the convenience and safety of double-sided adhesive peeling. The use efficiency avoids the damage to the nails caused by frequent stripping of the double-sided adhesive tape. At the same time, the invention innovatively proposes the preparation device and method of the double-sided adhesive tape with the tooth-edge peeling structure, which realizes the continuous production of the tooth-edge double-sided adhesive tape. It has broad market promotion and application prospects.

Description

technical field [0001] The invention relates to the technical field of adhesive tapes, in particular to a tooth-edged double-sided adhesive capable of quickly peeling off a release paper, and a preparation device and method thereof. Background technique [0002] The double-sided tape widely used in the prior art generally includes a release paper and a cotton glue layer pasted on the release paper. This cotton glue layer is formed by coating the glue layer on both sides of the tissue paper, and has double-sided adhesive performance. , When using, paste it on the adherend through one side of the cotton glue layer, and then peel off the release paper on the other side of the cotton glue layer to achieve the purpose of double-sided sticking. The existing double-sided adhesive tape does not consider the peeling convenience of the release paper in the structural design and preparation process. The common double-sided adhesive tape on the market has almost the same width as the re...

Problems solved by technology

The existing double-sided adhesive tape does not consider the peeling convenience of the release paper in the structural design and preparation process. The common double-sided adhesive tape on the market has almost the same width as the release paper and tissue paper. Release paper is more difficult, and for operators who frequently use double-sided tape, frequently peeling off the existing double-sided tape will not only damage the fingernails, but also affect the work effect

In order to solve the problem of difficult peeling of the release paper, some manufacturers also provide double-sided tape with a release paper peeling structure at the end of the tape, but it can only provide convenience for the first peeling of the double-sided tape. If the double-sided tape cannot After being used once, it becomes more difficult to peel off the release paper because there is no longer a release paper peeling structure in the subsequent use process. Therefore, in the prior art, there is no structure that is easy to peel off on the double-sided adhesive tape. Now The peeling convenience of double-sided tape is not considered in the existing technology
