[0002] Webbing is a plain or tubular fabric made by interlacing various yarns as warp and weft. Webbing fabrics come in a wide variety and are widely used in various industries such as clothing, footwear, bags, industry, agriculture, military supplies, and transportation. It plays a crucial role in the structural adjustment and optimization of China's textile industry. After weaving, webbing needs to be tested for abrasion resistance to determine its fatigue strength and prevent defective products. However, the testing equipment typically involves repeatedly rubbing the webbing back and forth on a testing cylinder, and the range of movement of the webbing is fixed. This results in different test areas, and when the test area is large, the webbing position needs to be changed multiple times, affecting testing efficiency. Utility Model Content

Detailed Implementation

[0023] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] Example 1

[0025] Since the webbing's movement range is fixed, the test results will differ depending on the test area. When the test area is large, the webbing position needs to be changed multiple times, affecting testing efficiency. (Refer to...) Figures 1-6This embodiment proposes an abrasion resistance testing device for webbing. The testing area of ​​the webbing can be changed by adjusting the device 2. The device includes a support platform 1, a support frame 8 fixedly mounted on the top of the support platform 1, and two symmetrical L-shaped plates 9 fixedly mounted on the top of the support platform 1. A turntable 10 is rotatably mounted on the inner wall of the support frame 8. The adjusting device 2 includes adjusting grooves 21 on both sides of the turntable 10. Two sets of symmetrical fixing rods 22 are fixedly mounted on the inner wall of the adjusting grooves 21, making the movement of the adjusting column 24 more stable. A threaded rod 23 is rotatably mounted on the inner wall of the adjusting grooves 21, and an adjusting column 24 threadedly connected to the threaded rod 23 is slidably mounted on the inner wall of the adjusting grooves 21. A toothed plate 25 is fixedly mounted on the adjusting column 24. A toothed plate 25 is rotatably mounted on the inner wall of the turntable 10. The gear 26 meshes with the toothed plate 25. A T-shaped rod 27 is slidably mounted on the L-shaped plate 9. A slot 28 is opened on the T-shaped rod 27. The adjusting column 24 can move within the slot 28. When it is necessary to increase the test area of ​​the webbing, the threaded rod 23 is rotated to drive the adjusting column 24 on one side of the turntable 10 to move towards the edge of the turntable 10. The movement of the adjusting column 24 drives the toothed plate 25 to move. The movement of the toothed plate 25 drives the gear 26 to rotate, so that the adjusting column 24 on the other side of the turntable 10 moves towards the edge of the turntable 10. When the turntable 10 rotates under the action of the driving device 6, the adjusting column 24 moves within the slot 28. The closer the adjusting column 24 is to the edge of the turntable 10, the greater the vertical movement of the T-shaped rod 27, which increases the range of movement of the webbing and its test area.

[0026] To test webbing of different sizes, a telescopic device 3 is installed on the T-shaped rod 27. The telescopic device 3 includes a sliding column 32 that is slidably installed on the T-shaped rod 27. A telescopic groove 31 is provided on the T-shaped rod 27. A fixing bolt 33 that is threadedly connected to the sliding column 32 is slidably installed on the inner wall of the telescopic groove 31. The position of the fixing device 5 on the sliding column 32 is changed by fixing bolt 33, so that webbing of different sizes can be fixed.

[0027] Example 2

[0028] Based on Embodiment 1, the technical solution proposed in Embodiment 1 is used to solve the drawback that the test range of the webbing cannot be adjusted. When adjusting the test position of the webbing, due to the long test time, when the webbing applies pressure to the test cylinder 74, the simple clamping device 4 causes the webbing to shift, resulting in deviation of the test results.

[0029] Reference Figures 1-6A clamping device 4 is installed on the sliding column 32. The clamping device 4 includes a support plate 41 fixedly installed on the top of the sliding column 32. Two limiting grooves 42 are symmetrically opened on the support plate 41. A bidirectional screw 43 is rotatably installed in the limiting groove 42. A clamping block 44 that meshes with the bidirectional screw 43 is slidably installed in the limiting groove 42. Rotating the bidirectional screw 43 causes the clamping block 44 to move towards each other in the limiting groove 42. The fixing device 5 can be removed from the connecting groove 51 by using the connecting block 55, and used to fix the webbing.

[0030] To adjust the test position of the webbing, a fixing device 5 is installed between the two sets of clamping blocks 44. The fixing device 5 includes a connecting groove 51 formed on the clamping block 44. An upper bracket 51 is installed between the two sets of clamping blocks 44. Several sets of protrusions 52 are installed at the bottom of the upper bracket 51. A lower bracket 53 is installed at the bottom of the upper bracket 51. Several sets of grooves 54 corresponding to the positions of the protrusions 52 are formed at the top of the lower bracket 53. The protrusions 52 and the grooves 54 work together to clamp the webbing, making the webbing clamped more firmly. Connecting blocks 55 are fixedly installed at both ends of the upper bracket 51 and the lower bracket 53. The fixing device 5 is removed from the connecting groove 51 by the clamping device 4, the upper bracket 51 and the lower bracket 53 are separated, the webbing is clamped between the upper bracket 51 and the lower bracket 53, and then the webbing is wrapped around the upper bracket 51 and the lower bracket 53. This not only prevents the position of the webbing from shifting, but also changes the test position of the webbing by the number of wrapping turns.

[0031] A drive device 6 is fixedly installed on the support platform 1. The drive device 6 includes a motor 61 fixedly installed on the support platform 1. A worm gear 62 is fixedly installed at the output end of the motor 61. A worm wheel ring 63 that meshes with the worm gear 62 is fixedly installed on the turntable 10. Starting the motor 61 causes the worm gear 62 to rotate, which in turn drives the turntable 10 connected to the worm wheel ring 63 to rotate.

[0032] To conduct abrasion resistance testing on the webbing, an abrasion device 7 is installed on the support platform 1. The abrasion device 7 includes an electric telescopic rod 71 fixedly installed on the support platform 1. By activating the electric telescopic rod 71, the test cylinder 74 on the connecting frame 72 is moved up and down to adjust the pressure between the webbing and the test cylinder 74. One end of the electric telescopic rod 71 is fixedly installed with the connecting frame 72, and a connecting screw 73 is fixedly installed on the connecting frame 72. The test cylinder 74 is sleeved on the connecting screw 73 and connected to the connecting screw 73 through a cross block on the test cylinder 74. The test cylinder 74 is then fixed by a knob 75 to facilitate the replacement of test cylinders 74 of different test types. A knob 75 is threadedly connected to the connecting screw 73.
