Description

Technical Field

[0001] The utility model belongs to the field of adhesive tape production, in particular to a tension release device when the adhesive tape is rolled up. Background Art

[0002] Adhesive tape is composed of two parts: base material and adhesive. It connects two or more unconnected objects together through bonding. There is a layer of adhesive on its surface. The adhesive can stick to things because its molecules form bonds with the molecules of the objects to be connected. This bond can firmly bond the molecules together. The composition of the adhesive includes various polymers according to different brands and types. In the prior art, the substrate of the tape is usually a PET or PC substrate. During production, the adhesive is evenly coated on the surface of the substrate through a shaft roller. In order to cope with assembly line production, the tape wire is wound into a cylindrical shape through a reel core, and the length of the wire can reach more than 5,000 meters. The cylindrical shape wound on the reel core is a mother roll. During production and use, the mother roll needs to be packaged, that is, the mother roll is opened and split into sub-rolls of about 200 meters. During packaging, the adhesive of the wire material of the package will adhere to the other surface of the substrate, and a certain tensile force needs to be applied, which causes the tape wire to be stretched and have a retraction tension. During actual use, the tape wire retracts, which will cause the actual length to be reduced, and then cause the sub-rolls to have the problem of incorrect counting length. Summary of the invention
