[0030] The preferred embodiments of the utility model will be described in detail below with reference to the drawings, so as to more clearly understand the purpose, characteristics and advantages of the utility model. It should be understood that the embodiments shown in the drawings are not a limitation on the scope of the utility model, but only to illustrate the essential spirit of the technical scheme of the utility model.

[0031] ​​In the following description, for purposes of explanation, specific details are set forth in order to provide a thorough understanding of various disclosed embodiments. It will be appreciated, however, that embodiments can be practiced in other ways without one or more of the specific details set forth in this description. In other instances, well-known devices, structures and techniques have not been shown or described in order to avoid unnecessarily obscuring embodiments.

[0032] Reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, the appearances of the phrase "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0033] In the following description, for the purpose of clarity, directional terms are used to describe the structure and working of the present application. However, the terms "front", "back", "left", "right", "outer", "inner", "outward", "inward", "up", "down", etc. should be understood as convenient terms and should not be interpreted as limiting terms.

[0034] With reference to Figures 1 to 4 The present application provides a kind of adhesive tape holding force testing machine, which includes mounting plate 1, one or several groups of test assembly 2 being arranged side by side on mounting plate 1, industrial computer and several operation buttons.

[0035] With reference to Figure 2 Several test assemblies 2 are arranged side by side on the bottom surface of mounting plate 1 along the length direction of mounting plate 1.

[0036] Test assembly 2 includes force sensor 21, experimental board 22 and counterweight 23. Force sensor 21 is installed on mounting plate 1. The upper end of experimental board 22 is connected with force sensor 21, and experimental board 22 is used for sticking with product 9 to be tested. Product 9 to be tested is stuck on experimental board 22 along the length direction (up-down direction / longitudinal direction) of experimental board 22, the lower part of product 9 to be tested extends from the bottom of experimental board 22, and the lower end of product 9 to be tested is pasted with counterweight 23, so as to provide weight by counterweight 23.

[0037] Industrial computer is integrated with microcontroller and display 3, and microcontroller is connected with force sensor 21 and display 3 respectively. Display 3 can display various parameters of each test assembly 2, such as current tension, detection duration of product 9 to be tested, etc.

[0038] The plurality of operation buttons are connected to the microcontroller respectively. The operation buttons may include a start button 41 and a stop button 42, and the start button 41 and the stop button 42 are connected to the microcontroller respectively.

[0039] When used, the present invention can simultaneously test multiple groups of identical or different products 9 to be tested. The products 9 to be tested can be attached to a test plate 22 in accordance with the standards GB 4851, Test Method for Holding Adhesion of Pressure-Sensitive Adhesive Tapes, JIS Z0237, Test Method for Pressure-Sensitive Adhesive Tapes and Sheets, ASTM D3654, and Determination of Shear Adhesion of Pressure-Sensitive Tapes. A counterweight 23 of a specified weight is suspended from the lower end of the products 9 to be tested. When the products 9 to be tested are attached to the test plate 22, the design of the counterweight 23 allows the force sensor 21 to detect a certain tensile force. Once the products 9 to be tested are detached from the test plate 22, the force sensor 21 no longer detects the tensile force. A start button 41 activates the microcontroller to start timing, which stops when the force sensor 21 no longer detects the tensile force. Therefore, the time it takes for the products 9 to be completely detached can be used to characterize the adhesive specimen's ability to resist pull-off.

[0040] The utility model is suitable for carrying out stickiness test on products such as pressure-sensitive adhesive tapes, self-adhesive stickers, plasters, and hot melt adhesives.

[0041] The microcontroller of the present invention can adopt existing technology, such as a microcontroller based on a PLC architecture or a microcontroller based on a single chip microcomputer architecture.

[0042] In one embodiment, the test assembly 2 further includes a suspension plate 24 , the upper end of the suspension plate 24 is fixed to the force sensor 21 , and the lower end of the suspension plate 24 is detachably connected to the upper end of the test plate 22 .

[0044] In one embodiment, the suspension plate 24 is L-shaped. The top horizontal section of the suspension plate 24 is fixed to the force sensor 21, and the lower end of the vertical section of the suspension plate 24 has a plug-in shaft. The upper end of the experiment board 22 has a plug-in port, and the plug-in port connects the plug-in shaft to achieve a detachable connection between the suspension plate 24 and the experiment board 22.

[0050] By pasting the connecting section of the triangular ring 25 with the lower end of the product 9 to be tested, the pasting of the two can be more firm and reliable. Figure 4 As shown, the lower end of the product 9 to be tested is pasted with itself after passing around the connecting section, avoiding the tearing of the product 9 to be tested due to the counterweight 23 on the lower end, and even tearing the product 9 to be tested.
