Description

Technical Field

[0001] The utility model relates to the technical field of unwinding strength testing, in particular to an unwinding strength testing device. Background Art

[0002] The unwinding strength reflects the applicability of the tape on the automatic packaging machine. If the unwinding strength is too large, the tape will show different degrees of fracture and elongation and rebound phenomena, affecting the production efficiency. During pasting application, there will also be quality defects such as retraction and unevenness, thus affecting the bonding effect and bringing quality hazards. The tape unwinding force refers to the force required for the tape during the unwinding process at a certain speed. Therefore, it is necessary to test the unwinding strength of the tape;

[0032] Embodiment 2

[0033] As Figures 1-3As shown in the figure, the lead screw 102 is rotatably connected to the base 1. The first slider 103 is adapted to the lead screw 102. The first slider 103 is slidably connected to the first chute 101. The lead screw 102 can drive the first slider 103 to perform a linear reciprocating motion, so that the first slider 103 can drive the fixing component 2 to move back and forth, completing the unwinding strength test. The second slider 105 is slidably connected to the second chute 104. The clamping seat 303 is fixedly connected to the second slider 105. By the sliding connection between the clamping seat 303 and the second slider 105, the friction when the clamping seat 303 moves can be reduced, improving the test accuracy. The fixing frame 201 is fixedly connected to the first slider 103. The sleeve 202 is fixedly connected to the fixing frame 201. The first threaded rod 203 is adapted to the sleeve 202. The anti-slip piece 204 is fixedly connected to the first threaded rod 203. By using the sleeve 202, the tape roll can be sleeved around its periphery, and the anti-slip piece 204 is used to limit it, preventing the tape roll from falling off during the test and improving the use stability. The fixing seat 301 is fixedly connected to the base 1. The spring dynamometer 302 is adapted to the fixing seat 301. By the fixed connection between the fixing seat 301 and the base 1, the fixing seat 301 can be made more firm, so as to better fix the spring dynamometer 302 during the test and improve the use stability. The output end of the spring dynamometer 302 is fixedly connected to the clamping seat 303. The second threaded rod 304 is adapted to the clamping seat 303.

[0034] The working process of the present utility model: When using a tape roll to perform an unwinding strength test on an unwinding strength test device, first sleeve the tape roll around the periphery of the sleeve 202, rotate the anti-slip piece 204 to make the first threaded rod 203 screw into the inside of the sleeve 202, completing the placement work of the tape roll. Uncover one end of the tape roll, place it inside the clamping seat 303, and rotate the second threaded rod 304 to drive the clamping block 305 to cooperate with the clamping seat 303 to complete the clamping work of the tape. Rotate the lead screw 102 to drive the tape roll to move uniformly forward through the first slider 103, the first chute 101 and the fixing component 2. During the process, under the action of the pulling force, the tape will drive the clamping seat 303 to move forward synchronously through the second chute 104 of the second slider. At the same time, the forward pulling force will trigger the pointer on the spring dynamometer 302 to point to the corresponding value, achieving the purpose of detection. Compared with the traditional unwinding strength test device, its mechanical mechanism is relatively simple, can simply and effectively perform the unwinding strength test, greatly reducing its maintenance cost and effectively meeting the use requirements of small enterprises.
