DETAILED DESCRIPTION

[0025] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0026] Embodiment 1

[0027] like Figure 1-Figure 3 As shown, the utility model proposes a device for testing the adhesion of a tape, comprising a test bench 1, a limit seat 4, a movable seat 5 and a test assembly. The limit seat 4 is symmetrically arranged on the top of the test bench 1, and a positioning groove 2 located between two groups of limit seats 4 is opened on the upper end surface thereof. An adhesion plate 3 and a fixing assembly for limiting and fixing the adhesion plate 3 are arranged in the positioning groove 2. The movable seat 5 is slidably arranged between the two groups of limit seats 4. One side of the movable seat 5 is connected to the adhesion plate 3 through the test tape, and the other side of the movable seat 5 is arranged with a test assembly, and the test assembly has a pulling mechanism for pulling the tape.

[0028] like Figure 3 As shown, a pressure plate 6 is slidably provided on the inner side of the movable seat 5, and a threaded rod 7 is rotatably connected to the pressure plate 6 through a bearing. The top of the threaded rod 7 passes through the movable seat 5 and is connected to a handle 8. A threaded hole that matches the thread of the movable seat 5 is provided at the connection between the movable seat 5 and the threaded rod 7. By rotating the handle 8, the threaded rod 7 can be driven to screw downward relative to the movable seat 5. During the screwing process, the pressure plate 6 is driven to press one end of the tape.

[0029] like Figure 2 As shown, the fixing assembly includes a fixing plate 9, a screw rod 10, a threaded sleeve 12 and a connecting rod 13. The fixing plate 9 is slidably arranged in the positioning groove 2, and one side of the screw rod 10 is abutted against the adhesion plate 3. The screw rod 10 is rotatably arranged in the positioning groove 2, and one end of the screw rod 10 passes through the test bench 1 and is connected to a handwheel 11. The middle part of the screw rod 10 is threadedly connected to the threaded sleeve 12, and the threaded sleeve 12 is slidably connected to the positioning groove 2, and a connecting rod 13 is rotatably arranged between the threaded sleeve 12 and the pressure plate 6.

[0030] The hand wheel 11 drives the screw rod 10 to rotate, and during the rotation of the screw rod 10, the thread sleeve 12 drives one end of the connecting rod 13 to perform linear motion, and the other end of the connecting rod 13 drives the fixing plate 9 to press and fix the side surface of the adhesion plate 3.

[0031] Furthermore, the upper end surface of the adhesion plate 3 and the adhesion surface inside the movable seat 5 are located on the same horizontal plane.

[0032] like Figure 3 As shown, the test assembly includes a test box 14, a movable plate 15, a pressure sensor 16 and a connecting plate 17. The movable plate 15 is slidably arranged in the test box 14, and connecting plates 17 are arranged at both ends of one side of the movable plate 15. One end of the two connecting plates 17 passes through the test box 14 and is connected to the movable seat 5; the pressure sensor 16 is arranged in the middle of one side of the movable plate 15 in the test box 14, and its sensing end is arranged corresponding to the movable plate 15.

[0033] Further, such as Figure 1 As shown, guide pillars 23 are provided on the inner sides of the two groups of limit seats 4, and the two ends of the movable seat 5 are respectively sleeved on the corresponding guide pillars 23.

[0034] Embodiment 2

[0035] like Figure 1-Figure 3 As shown, the utility model proposes a device for testing the adhesion of an adhesive tape. Based on the above embodiments, this embodiment records in detail the specific components of the pulling mechanism and the connection method thereof with the testing component.

[0036] like Figure 1 As shown, the pulling mechanism includes a reel 18, a pull belt 19 and a fixed shaft 20. A mounting plate 21 is provided at one end of each of the two limit seats 4. The reel 18 is rotatably arranged between the two sets of mounting plates 21. The fixed shaft 20 is embedded in the middle of the back side of the test box 14. A pull belt 19 is connected between the fixed shaft 20 and the reel 18. A turntable 22 is provided at the end of the reel 18.

[0037] The reel 18 is driven to rotate by the turntable 22 . During the rotation, the reel 18 winds around the drawstring 19 , and then applies a pulling force to the test box 14 through the fixed shaft 20 .

[0038] In summary, when the utility model is in use, one end of the adhesive tape to be tested is glued to the bottom of the inner side of the movable seat 5, and the other end is glued to the upper end surface of the adhesive plate 3, and then the handle 8 is turned, and the handle 8 drives the pressing plate 6 to move downward through the threaded rod 7 until the pressing plate 6 presses and fixes the adhesive tape, and then the turntable 22 is turned, and the turntable 22 drives the reel 18 to rotate. During the rotation of the reel 18, the pull belt 19 is wound, so that the pull belt 19 pulls the test box 14 to move in the direction of the reel 18. During the movement, the test box 14 first undergoes relative displacement with the movable seat 5, and as the pulling force is sustained, the test box 14 is displaced relative to the movable seat 5. As the pressure sensor 16 continues to increase, its relative displacement spacing also becomes larger until the internal pressure sensor 16 contacts with the movable plate 15. At this time, the pressure sensor 16 senses the reverse force applied to it by the movable seat 5. Under the action of the tape, the movable seat 5 maintains its position unchanged until the tension separates the tape from the adhesion plate 3. At this time, the adhesion of the tape can be tested by the force applied to the pressure sensor 16, and the fixed plate 9 can be driven to move by turning the handwheel 11, thereby releasing the limiting force applied to the fixed plate 9, making it convenient to replace the adhesion plates 3 with different adhesion surfaces.

[0039] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
