Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tape detection equipment, and particularly relates to an adhesive tape adhesion detection device. Background Art

[0002] An adhesive tape is made by using paper, cloth, or film as a base material and evenly coating glue on the above base material to make a paper adhesive tape, a cloth adhesive tape, or a film adhesive tape. According to the glue property, it can be divided into solvent-based adhesive tape, emulsion-based adhesive tape, hot-melt adhesive tape, calendered adhesive tape, and reactive adhesive tape, which is composed of three parts: a base material, an adhesive, and a release paper (film). The adhesive tape is characterized by strong adhesion, good toughness, and strong tensile strength, so it is widely used in leather goods, shoes, and other places where enhanced tensile strength is required. In addition, the use of the adhesive tape is very convenient. Only a certain pressure needs to be applied to make it adhere to the surface of other objects, without the need for pretreatment steps such as coating and mixing, nor waiting for curing.

[0003] After the production and processing of the adhesive tape, its adhesion needs to be detected to ensure that the product has qualified quality. After retrieval, the Chinese patent application number is: CN202320648993.8, which discloses a tape adhesion detection device, including a base, guide rods, a force-bearing plate, a pressing block, and a testing mechanism; the number of the guide rods is two, and both of the two guide rods are vertically connected to the base; the force-bearing plate is rotatably connected to the guide rods, and the rotation axis of the force-bearing plate is horizontally arranged; the pressing block is slidably connected to the guide rods, and the pressing block can abut against the force-bearing plate; the testing mechanism is installed on the base and is used to apply a pulling force to the tape adhered to the force-bearing plate; this application has the effects of facilitating the installation of the guide rods through the base, facilitating the installation of the force-bearing plate and the pressing block through the guide rods, facilitating the testing of the adhesion of the tape through the testing mechanism, and facilitating the equivalent pressing of the tape by the pressing block in cooperation with the force-bearing plate, thereby improving the detection accuracy of the tape adhesion.

[0004] The above technical solution still has defects. First, the detection environment is exposed, which easily causes impurities such as dust to adhere to the adhesive surface of the tape, reducing the adhesion and resulting in inaccurate detection results; in addition, in the above solution, the tape is adhered to the force-bearing plate, and then the tape is pulled by a tensiometer for testing. In this way, on the one hand, the tape is likely to remain on the force-bearing plate. When conducting multiple tests, the remaining tape needs to be removed, increasing the complexity of the test. On the other hand, using the hanging rod of the tensiometer to hang and pull the tape makes the force on the tape uneven and the test results inaccurate. Therefore, we need to propose an adhesive tape adhesion detection device. Content of the Utility Model
