Description

Technical Field

[0001] This utility model relates to the field of double-sided tape technology, specifically to an adhesive tape that is convenient for fixed-length use. Background Technology

[0002] Adhesive tape, as a widely used connection and functional material in modern industry and life, has multiple functions, including physical connection, functional protection, and surface decoration. In the manufacturing of electronic devices, adhesive tape can be used to achieve rapid positioning and fixation of precision components such as camera modules and screens.

[0003] For example, the utility model patent disclosed in publication number CN210620691U discloses an adhesive tape, comprising an adhesive tape intermediate body, with multiple edge bodies fixedly connected to both sides of the intermediate body, and venting grooves provided between the edge bodies. Circular holes are formed on the front sidewalls of the edge bodies. An outer release film is adhered to the front sidewall of the intermediate body. An adhesive layer, which is an oil-based acrylic adhesive, is coated on the side of the intermediate body away from the outer release film. A release layer is adhered to the side of the adhesive layer away from the intermediate body. This utility model effectively improves the service life and fixation stability of the adhesive tape.

[0004] Although the aforementioned adhesive tape has a certain degree of stability, it is not convenient to use it in fixed lengths as needed. This makes it difficult to use the tape quickly without a tool. In addition, the release film of the adhesive tape has insufficient tear resistance. Therefore, there is an urgent need for an adhesive tape that is convenient for fixed-length use to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an adhesive tape that is convenient for fixed-length application, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adhesive tape for convenient fixed-length application, comprising a double-sided adhesive layer, wherein four sets of second fracture holes are equidistantly provided on the inner end face of the double-sided adhesive layer, and release film layers are provided on both the upper and lower parts of the double-sided adhesive layer, and four sets of adhesive grooves are equidistantly provided on the upper end face of the release film layer.

[0007] A support mesh layer is fixedly disposed on the inner end face of the adhesive groove, and three sets of third fracture holes are equidistantly provided on the upper end face of the release film layer.

[0008] The outer sheath of the tape is fixedly disposed on the outer end face of the release film layer. Three sets of first fracture holes are equally spaced on the inner end face of the outer sheath of the tape, and reinforcing strips are equally spaced on the upper end face of the outer sheath of the tape.

[0009] Preferably, the first fracture hole, the second fracture hole, and the third fracture hole are located on the same straight line, which can improve the regularity of the subsequent adhesive tape breakage.

[0010] Preferably, the release film layer is made of PET, which can effectively improve the protective performance of the double-sided adhesive layer.

[0011] Preferably, the support mesh layer is made of BOPP, which has high transparency, high gloss and good mechanical properties, and can effectively improve the strength between the outer sheath of the tape and the release film layer.

[0012] Preferably, the outer protective layer of the tape is made of PVC, which can effectively improve the external protection of the adhesive tape.

[0013] Preferably, the reinforcing strip is made of PI, which has excellent high temperature resistance, mechanical strength and chemical stability. The reinforcing strip outside the outer sheath of the tape can improve the support stability of the release film, thereby improving the stability of the subsequent separation of the release film layer from the double-sided adhesive layer.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting a first fracture hole, a second fracture hole, a third fracture hole, and a reinforcing strip, and by sequentially setting the first fracture hole, the third fracture hole, and the second fracture hole inside the outer protective layer of the tape, allows users to quickly separate the double-sided tape to a fixed length, effectively improving the convenience of using the double-sided tape to a fixed length when it is detached from the blade. At the same time, the support mesh layer and the reinforcing strip provide sufficient support for the release film layer and the outer protective layer of the tape, so that the release film part outside the adhesive groove has good tear resistance and deformation resistance, thereby preventing the release film from curling and improving the stability of the subsequent separation of the release film layer and the double-sided adhesive layer.
