Abstract
Description
Technical Field
[0001] This utility model relates to the field of adhesive tape technology, specifically a composite adhesive tape structure with easily separable release paper. Background Technology
[0002] Adhesive tape consists of two parts: a substrate and an adhesive. It connects two or more unconnected objects together by bonding. Its surface is coated with an adhesive. The earliest adhesives came from animals and plants. In the 19th century, rubber was the main component of adhesives. Nowadays, various polymers are widely used. Adhesives can stick things together because their molecules form bonds with the molecules of the objects to be connected. These bonds can firmly bind the molecules together. The composition of adhesives varies depending on the brand and type, and includes various polymers.
[0003] Chinese Patent 202123295638.7 relates to the field of adhesive tape, specifically a composite tape with an easy-tear release liner. The tape includes a substrate layer, a flame-retardant and heat-insulating layer, an antibacterial layer, an adhesive layer, and an easy-tear release liner layer. The flame-retardant and heat-insulating layer is disposed below the substrate layer; the antibacterial layer is disposed below the flame-retardant and heat-insulating layer; the adhesive layer is disposed below the antibacterial layer; and the easy-tear release liner layer is disposed below the adhesive layer. The easy-tear release liner layer also includes several easy-tear portions; an easy-tear groove is formed in the center of the easy-tear release liner layer, and a perforated tear line is provided inside the easy-tear groove. This utility model provides a convenient and easy-to-use composite tape with an easy-tear release liner.
[0004] When using composite tape, the release paper needs to be separated. Because the adhesive layer has good adhesion and the composite tape is firmly stuck together on all four sides, when separating the release paper, it is necessary to manually pry open a corner around the composite tape to remove the release paper. Peeling off the release paper will cause the edges of the composite tape to curl, which may attract some dust and affect the use of the composite tape.
[0005] Therefore, a composite tape structure that allows for easy separation of the release paper is proposed to address the above problems. Utility Model Content

[0025] like Figure 1 As shown, a composite tape structure with easily separable release paper includes a release paper easily separable composite tape structure shell 1, a composite tape assembly 2 is disposed inside the release paper easily separable composite tape structure shell 1, and a composite tape mounting and positioning assembly 3 is installed on the side of the composite tape assembly 2, and a composite tape cutting assembly 4 is disposed on the side of the release paper easily separable composite tape structure shell 1.
[0026] like Figure 2 As shown, a composite tape structure with easily separable release paper is disclosed. The composite tape assembly 2 includes a release paper layer 201, an adhesive layer 202, a non-adhesive layer 203, and a substrate layer 204. The non-adhesive layer 203 is symmetrically arranged about the vertical central axis of the adhesive layer 202, and the adhesive layer 202 is located between the release paper layer 201 and the substrate layer 204. The release paper layer 201 and the substrate layer 204 form a detachable structure through the adhesive layer 202. The non-adhesive layer 203 is provided on the side of the adhesive layer 202, and the release paper layer 201 can be easily torn off through the non-adhesive layer 203, which facilitates the separation of the release paper layer 201 and improves the convenience of using the composite tape.
[0027] like Figure 3 , Figure 4As shown, a composite tape structure with easily separable release paper includes a composite tape mounting and positioning assembly 3, comprising a positioning rod body 301, a positioning rod slot 302, a first arc-shaped clamping block 304, a clamping block rotating shaft 305, a second arc-shaped clamping block 306, and a clamping block spring 307. The positioning rod body 301 and the positioning rod slot 302 form an engaging structure, and the positioning rod body 301 forms a rotating structure with the outer shell 1 of the easily separable release paper composite tape structure via the positioning rod rotating shaft 303. The first arc-shaped clamping block 304 forms a rotating structure with the positioning rod body 301 via the clamping block rotating shaft 305, and the first arc-shaped clamping block 304 forms an elastic structure with the second arc-shaped clamping block 306 via the clamping block spring 307, thereby holding the positioning rod body 301 in place. 1. Rotate around the positioning rod pivot 303 to open the positioning rod body 301. Then, install the composite tape assembly 2 inside the composite tape structure shell 1 where the release paper is easily separated. Then, close the positioning rod body 301 so that the positioning rod body 301 is locked inside the positioning rod slot 302. The first arc-shaped clamping block 304 rotates around the clamping block pivot 305 so that the positioning rod body 301 can enter the interior of the second arc-shaped clamping block 306.

The first arc-shaped clamping block 304 rotates around the clamping block pivot 305, allowing the positioning rod body 301 to enter the second arc-shaped clamping block 306. Under the elastic action of the clamping block spring 307, the first arc-shaped clamping block 304 can hold the positioning rod body 301... 1. Clamp to ensure the stability of the positioning rod body 301. Then, during use, when it is necessary to cut the composite tape assembly 2, push the cutting blade 401 upward so that the cutting blade 401 cuts the composite tape assembly 2. After cutting, release the cutting blade 401. Under the elastic action of the blade spring 402, the cutting blade 401 is pulled back to the initial position.
