Description

Technical Field

[0001] This invention relates to the field of textile fabric testing technology, specifically to a device and method for testing the abrasion resistance of textile fabrics used in production. Background Technology

[0002] Abrasion resistance is one of the core quality indicators of textile fabrics, directly determining the service life and user experience of textile products. Therefore, accurate testing of the abrasion resistance of textile fabrics is a key aspect of quality control in the textile industry. Currently, most devices for testing the abrasion resistance of existing clothing textile fabrics use a single friction mode (such as the Martindale method's rotational friction or simple reciprocating friction). These devices can only simulate wear under a single usage scenario. However, in actual use, textile fabrics often experience reciprocating friction, rotational friction, and even impact friction simultaneously (such as at the elbows and cuffs of clothing). The results of single-mode testing deviate significantly from actual usage conditions and cannot comprehensively reflect the abrasion resistance of the fabric. Furthermore, when testing existing clothing textile fabrics, it is difficult to specifically simulate real-world environments (such as sweat, dust, plant debris, and other media adhering to the surface of clothing), leading to significant discrepancies between test results and actual usage conditions. Additionally, due to the large test area, the resistance generated by fabric friction is evenly distributed, making it difficult to specifically test the abrasion resistance of the warp and weft threads in the fabric.

[0003] The existing technology has the following problems:

[0004] 1. In the use of existing abrasion resistance testing devices for textile fabric production, the large friction area of ​​the rotary abrasion resistance test method causes the resistance generated by fabric friction to be evenly distributed, making it difficult to specifically test the abrasion resistance of the warp and weft threads in the fabric.

[0005] 2. Existing abrasion resistance testing devices for textile fabric production often use rigid friction heads to conduct friction tests with fixed force and angle, which leads to the friction method being out of touch with actual use scenarios, resulting in inaccurate test results. Summary of the Invention

[0006] This invention provides a device and method for testing the abrasion resistance of textile fabrics to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

A base is fixedly connected to the top of the limiting disks.

[0011] A further improvement of the technical solution of the present invention is that: two first gears and two second gears are rotatably connected to the end of the inner wall of the stabilizing chamber away from the slide groove. The two first gears are respectively meshed on both sides of the toothed plate, and the two second gears are respectively meshed on both sides of the toothed plate.

A lead screw is fixedly connected to the top of the second linkage gear rod, and the end of the lead screw is rotatably connected to the outer wall of the fixed box. The outer wall of the lead screw is threadedly connected to the U-shaped plate.

[0017] A further improvement of the technical solution of the present invention is that: a return spring is fixedly connected to the center of the bottom of the support frame, and a moving block is fixedly connected to the end of the return spring. The bottom of the outer wall of the moving block is tapered, and a support rod is slidably connected to the inner wall of the moving block. A fixing block is fixedly connected to the bottom of the support rod, and the bottom of the fixing block is fixedly connected to the bottom of the inner wall of the fixing box. Several elastic rods are rotatably connected to the top of the fixing block, and steel balls are fixedly connected to the ends of the elastic rods. The outer walls of the steel balls are slidably connected to the inner wall of the push tube and the outer wall of the moving block, respectively.

[0018] A method for testing the abrasion resistance of textile fabrics, the method employing the aforementioned abrasion resistance testing device for textile fabric production, as described below:

[0019] S1: By setting mutually symmetrical limiting rings at one end of the top of the detection body, and setting a limiting plate on the inner wall of the limiting rings, by setting a base on the top of the limiting plate, and setting an extension rod on the inner wall of the base, by setting a first mounting block on the top of the extension rod, the abrasive is wrapped around the surface of the first mounting block, and then the first mounting ring is installed on the outer wall of the first mounting block to fix the abrasive. By wrapping the bottom of the second mounting block with textile fabric, and then installing the second mounting ring on the outer wall of the second mounting block to fix the textile fabric, and then using the fixing post set at the center of the top of the second mounting block to insert the fixing post into the mounting plate to fix the second mounting block.

[0020] S2: When it is necessary to conduct an abrasion resistance test on the entire textile fabric, several symmetrical control chambers are set on the inner wall of the test body, and the transmission components set on the inner wall of the control chamber are activated.

[0021] The transmission assembly controls an electrically controlled turntable located at the bottom of the inner wall of the chamber. This turntable, via a fixed base, a fixed box, and a limiting plate, drives the extension rod, the first mounting block, and the abrasive to rotate and rub against the bottom of the textile fabric. During this process, as the electrically controlled telescopic platform descends, the second mounting block and the textile fabric apply pressure to the first mounting block and the abrasive. As the extension rod deflects, the traction rope pulls the push tube, which, in conjunction with the steel balls, squeezes the moving block. As the moving block moves upward, it applies pressure to the return spring. This causes the rebound force of the return spring and the traction force of the traction rope to form a relative force, ensuring that the abrasive always adheres to the textile fabric while converting rigid friction into elastic friction, thus simulating the wear and tear of textile fabric in reality.

[0022] S3: When a radial abrasion resistance test is required, activate the elastic component to perform radial reciprocating friction on the bottom of the textile fabric.

[0023] The elastic component drives a first transmission gear rod via a first motor located on one side of the outer wall of the stabilizing chamber. This first transmission gear rod, through first linkage gear rods located on both sides of the outer wall, drives a first synchronizing rod to rotate. Since the inner wall of the stabilizing chamber has two first gears and two second gears, the two first gears mesh with both sides of the toothed plate, and the two second gears mesh with both sides of the toothed plate, and one end of each of the first and second gears is respectively equipped with a first synchronizing rod and a second synchronizing rod, and the first and second synchronizing rods located on the same side of the toothed plate are connected by a synchronous belt, the first motor drives the first and second gears, controlling the reciprocating movement of the toothed plate inside the stabilizing chamber. This, combined with the reciprocating up-and-down movement of the electrically controlled telescopic table, allows for the overall radial abrasion resistance test of the textile fabric.

[0024] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0025] 1. This invention provides a device and method for testing the abrasion resistance of textile fabrics. An elastic plate drives a fixed plate, a second mounting block, and the textile fabric, pushing a first mounting block coated with abrasive. During this process, an electrically controlled telescopic platform continuously moves downwards, using a base as a fulcrum to tilt the extension rod, the first mounting block, and the abrasive. Subsequently, a first motor drives the elastic plate and fixed plate to move via a toothed plate, causing the textile fabric and abrasive to reciprocate and rub against each other. This further solves the problem that in traditional abrasion resistance testing devices for textile fabrics, the large friction area of ​​the rotary abrasion resistance test method leads to the uniform dispersion of resistance generated by fabric friction, making it difficult to specifically test the abrasion resistance of the warp or weft threads in the fabric.

[0026] 2. This invention provides a device and method for testing the abrasion resistance of textile fabrics. A support rod is positioned at the center of the top of a fixed block, with its outer wall inside the inner wall of a moving block. This causes the moving block, compressed by steel balls, to move upwards under the constraint of the support rod, compressing a return spring at its top. The rebound force generated by the return spring interacts with the tension generated by the extension rod pulling the traction rope, ensuring the abrasive remains in contact with the textile fabric surface. Simultaneously, the height of the fixed plate is continuously and slightly controlled by an electrically controlled telescopic platform, causing the abrasive to rub along an irregular wave trajectory on the bottom of the textile fabric. This further solves the problem that traditional abrasion resistance testing devices for textile fabrics often use rigid friction heads for fixed-force and fixed-angle friction tests, resulting in friction methods that are out of sync with actual usage scenarios and thus inaccurate test results.

[0039] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0040] like Figures 1 to 11As shown in the embodiment of the present invention, a wear resistance testing device for textile fabric production includes a testing body 1. A plurality of mutually symmetrical limiting rings 2 are fixedly connected to one end of the top of the testing body 1, and the inner walls of the limiting rings 2 are rotatably connected to limiting disks 3. A base 4 is fixedly connected to the top of the limiting disks 3, and an extension rod 5 is rotatably connected to the inner wall of the base 4. A first mounting block 6 is fixedly connected to the top of the extension rod 5, and a first mounting ring 7 is threadedly connected to the outer wall of the first mounting block 6. An abrasive 8 is held between the first mounting block 6 and the first mounting ring 7. An electrically controlled telescopic platform 9 is fixedly connected to the top of the testing body 1 away from the limiting rings 2, and an elastic component is provided at the output end of the electrically controlled telescopic platform 9. The inner wall of the testing body 1... The unit has control chambers 10 corresponding to the limiting rings 2 one by one, and the inner walls of the control chambers 10 are equipped with transmission components. The elastic components include a stabilizing chamber 11 fixedly connected to the output end of the electric telescopic platform 9, and the inner wall of the stabilizing chamber 11 has a sliding groove 12. The inner wall of the sliding groove 12 is slidably connected to a limiting block 13. A toothed plate 14 is fixedly connected to one side of the outer wall of the limiting block 13, and an elastic plate 15 is fixedly connected to the end of the toothed plate 14. A fixing plate 16 is fixedly connected to the top of the elastic plate 15. The inner cavity of the fixing plate 16 is fixedly connected to a mounting plate 17 corresponding to the abrasive 8 one by one, and a fixing post 18 is slidably connected to the inner wall of the mounting plate 17. The end of the fixing post 18 is fixedly connected to a second mounting block 19. The outer wall of the stabilizing chamber 11 is threaded with a second mounting ring 20, and a textile fabric 21 is held between the second mounting block 19 and the second mounting ring 20. Two first gears 22 and two second gears 23 are rotatably connected to the inner wall of the stabilizing chamber 11 away from the slide groove 12. The two first gears 22 mesh with both sides of the toothed plate 14, and the two second gears 23 mesh with both sides of the toothed plate 14. A first synchronizing rod 24 and a second synchronizing rod 25 are fixedly connected to one end of each of the first gears 22 and the second gear 23, respectively. The outer walls of the first synchronizing rods 24 and the second synchronizing rods 25 penetrate the side wall of the stabilizing chamber 11 and are rotatably connected to it. A transmission connection is established between the outer walls of the first synchronizing rods 24 and the second synchronizing rods 25 located on the same side of the toothed plate 14. A synchronous belt 55 is provided. A first motor 26 is fixedly connected to one side of the outer wall of the stabilizing chamber 11, and a first transmission gear rod 27 is fixedly connected to the output end of the first motor 26. The end of the first transmission gear rod 27 is rotatably connected to the inner cavity of the stabilizing chamber 11. First linkage gear rods 28 are meshed on both sides of the outer wall of the first transmission gear rod 27, and the two first linkage gear rods 28 are respectively fixedly connected to the ends of the two first synchronous rods 24 away from the first gear 22. The inner wall of the mounting plate 17 is provided with a slot 29, and a tube 30 is inserted into the inner wall of the slot 29. Several insert plates 31 are fixedly connected to the bottom of the insert tube 30. The bottom of each of the insert plates 31 contacts a locking block 32, and the contact surface between the locking block 32 and the insert plate 31 is inclined.One end of the outer wall of several locking blocks 32 is engaged with the outer wall of the fixing post 18, and the outer wall of several locking blocks 32 is slidably connected to the inner wall of the slot 29 (spring rods 33 are fixedly connected to both sides of the outer wall of the locking blocks 32, and the ends of the spring rods 33 are fixedly connected to the inner wall of the slot 29).

[0041] During operation, several symmetrically arranged limiting rings 2 are set at one end of the top of the detection body 1, and limiting discs 3 are set on the inner walls of the limiting rings 2. A base 4 is set on the top of the limiting discs 3, and an extension rod 5 is set on the inner wall of the base 4. A first mounting block 6 is set on the top of the extension rod 5, and the abrasive 8 is attached to the surface of the first mounting block 6. Then, the first mounting ring 7 is installed on the outer wall of the first mounting block 6 to fix the abrasive 8. An electrically controlled telescopic table 9 is set at the top of the detection body 1 away from the limiting rings 2, and a stabilizing chamber 11 is set at the output end of the electrically controlled telescopic table 9. A toothed plate 14 is set on the inner wall of the stabilizing chamber 11, and an elastic plate 15 is set at the end of the toothed plate 14. A fixing plate 16 is set on the top of the elastic plate 15. Since the inner cavity of the fixing plate 16 is provided with several symmetrically arranged mounting discs 17, the cut textile fabric 21 is attached to the bottom of the second mounting block 19, and then the second mounting ring 20 is installed. The textile fabric 21 is fixed on the outer wall of the second mounting block 19. By setting a fixing post 18 at the center of the top of the second mounting block 19, the second mounting block 19 with the textile fabric 21 is inserted into the mounting plate 17 through the fixing post 18. (A slot 29 is set on the inner wall of the mounting plate 17, and the insertion tube 30 is inserted into the slot 29. Since there are several insertion plates 31 at the bottom of the insertion tube 30, as the insertion tube 30 is inserted, the insertion plates 31 push the locking block 32 set on the inner wall of the slot 29, and the inclined surface on one side of the locking block 32 is used as the force point, so that the side of the outer wall of the locking block 32 away from the inclined surface is embedded in the fixing post 18.) This fixes the second mounting block 19 to the bottom of the fixing plate 16. After several second mounting blocks 19 carrying textile fabric 21 are installed, the electric telescopic table 9 is started, so that the electric telescopic table 9 drives the fixing plate 16 to move down continuously until the surface of the textile fabric 21 contacts the surface of the abrasive 8.

[0042] It should be further explained that, due to the frequent radial reciprocating friction between clothing cuffs and tabletops during daily use, significant stress is placed on the warp and weft threads of the fabric. Therefore, by activating the first motor 26 located on one side of the outer wall of the stabilizing chamber 11, the output of the first motor 26 drives the first transmission gear rod 27 to rotate. Through the first linkage gear rods 28 located on both sides of the outer wall of the first transmission gear rod 27, the first transmission gear rod 27 drives the first synchronizing rod 24 to rotate synchronously. Since one end of the inner wall of the stabilizing chamber 11 is equipped with a first gear 22 and a second... Gear 23, and one end of the outer wall of the first gear 22 and the second gear 23 are respectively provided with a first synchronous rod 24 and a second synchronous rod 25. The first synchronous rod 24 and the second synchronous rod 25 located on the same side of the toothed plate 14 are connected by a synchronous belt 55 (here the synchronous belt 55 is composed of a synchronous pulley and a toothed belt, which is the prior art). So when the first linkage gear rod 28 drives the first synchronous rod 24, the second synchronous rod 25 is driven to rotate through the synchronous belt 55, so that the first gear 22 and the second gear 23 provided in the stable chamber 11 drive the toothed plate 14 to move in the stable chamber 11, so that the toothed plate 14 is connected to the first synchronous rod 24. The elastic plate 15 drives the fixed plate 16, the second mounting block 19, and the textile fabric 21 to move. During this time, the textile fabric 21 pushes the first mounting block 6, which is wrapped with abrasive 8. At the same time, the electrically controlled telescopic platform 9 continues to move downward, and with the base 4 as the fulcrum, the extension rod 5, the first mounting block 6, and the abrasive 8 tilt. When the contact point between the abrasive 8 and the textile fabric 21 moves away from the center of the bottom of the second mounting block 19, the electrically controlled telescopic platform 9 stops moving downward and restarts the first motor 26 to reverse, causing the first gear 22 and the second gear 23 to drive the toothed plate 14 to move towards the inner wall of the stabilizing chamber 11 again. During this time, the electrically controlled... The telescopic platform 9 is slowly raised until the contact point between the abrasive 8 and the textile fabric 21 returns to the center of the bottom of the second mounting block 19. The above-mentioned moving trajectory of the fixed plate 16 is repeated, so that the abrasive 8 and the textile fabric 21 move back and forth, realizing a small-range abrasion resistance test of the warp or weft of the textile fabric 21. This further solves the problem that in the process of using the traditional abrasion resistance testing device for textile fabric 21 production, the friction area of ​​the rotary abrasion resistance testing method is large, which causes the resistance generated by the friction of the fabric to be evenly distributed, making it difficult to conduct targeted abrasion resistance tests on the warp or weft of the fabric.

[0043] It should be reiterated that by setting a groove 12 on the inner wall of the stabilizing chamber 11, and by setting a limiting block 13 on the outer wall of the toothed plate 14 away from the elastic plate 15, and the limiting block 13 being located on the inner wall of the groove 12, when the testing body 1 performs a wear resistance test on a local warp or weft, the limiting block 13 supports the continuously moving toothed plate 14. This not only makes the movement trajectory of the fixed plate 16 more stable, but also reduces the problem of the toothed plate 14 shifting its center of gravity due to the influence of the elastic plate 15 and the fixed plate 16 when it reciprocates, thus causing wear on the first gear 22 and the second gear 23. After the test is completed, by setting spring rods 33 on both sides of the outer wall of the locking block 32, when the insertion tube 30 is pulled out of the slot 29, the spring force generated by the spring rods 33 causes the locking block 32 to re-enter the slot 29, thus removing the restriction on the fixed post 18.

[0044] The transmission assembly includes an electrically controlled turntable 34 fixed to the bottom of the inner wall of the control compartment 10, and a fixed base 35 is fixedly connected to the output end of the electrically controlled turntable 34. A fixed box 36 is fixedly connected to the center of the top of the fixed base 35. The fixed box 36 is fixedly connected to the limiting plate 3.

The outer wall of the lead screw 48 is threadedly connected to the U-shaped plate 44. A [missing information - likely a device or component] is fixedly connected to the center of the bottom of the support frame 41. A return spring 49 is provided, and a movable block 50 is fixedly connected to the end of the return spring 49. The bottom of the outer wall of the movable block 50 is tapered.

The bottom of the fixed block 52 is fixedly connected to the bottom of the inner wall of the fixed box 36. A number of elastic rods 53 are rotatably connected to the top of the fixed block 52. A steel ball 54 is fixedly connected to the end of each of the elastic rods 53. The outer wall of the steel ball 54 is slidably connected to the inner wall of the push tube 37 and the outer wall of the movable block 50, respectively.

[0045] During operation, several symmetrical control chambers 10 are set on the inner wall of the testing body 1, and an electrically controlled turntable 34 is set at the bottom of the inner wall of the control chamber 10. A fixed base 35 is set on the top of the electrically controlled turntable 34, and the fixed base 35 supports the fixed box 36 set at the center of the top. When it is necessary to conduct an overall abrasion resistance test on the textile fabric 21, salt water (here, salt water simulates human sweat), dust (here, dust simulates the textile fabric 21 being in a dusty environment), and plant debris (here, plant debris is composed of relatively hard plant debris such as straw or hay, used to simulate the textile fabric 21 being in an outdoor environment) are applied to the surface of three test samples respectively. Then, the three samples are fixed on three second mounting blocks 19 respectively. The interior of the fixed box 36 is interconnected with the interior of the limiting plate 3. A push tube 37 is installed at the bottom of one side of the inner wall of the fixed box 36, and several traction ropes 38 are installed at the top of the push tube 37. Since two extension plates 40 are installed at both ends of the bottom of the extension rod 5, and a guide tube 39 is installed between the two extension plates 40, with the bottom of the guide tube 39 connected to the end of the traction ropes 38, when the electrically controlled telescopic platform 9 controls the fixed plate 16, causing the second mounting block 19 and the textile fabric 21 to move downwards and press the extension rod 5 to cause it to deflect, the extension rod 5 drives the bottom-mounted guide tube 39 to rotate. This causes the guide tube 39 to pull the push tube 37 upwards within the fixed box 36 via the traction ropes 38. Since a support frame 41 is installed at the end of the inner wall of the fixed box 36 away from the push tube 37, and... A return spring 49 is provided at the center of the bottom of the support frame 41, and a moving block 50 is provided at the end of the return spring 49. Since a fixed block 52 is provided at the center of the bottom of the inner wall of the fixed box 36, and several elastic rods 53 are provided at the top of the fixed block 52, and steel balls 54 are provided at the ends of the elastic rods 53, when the push tube 37 moves upward, the inner wall of the push tube 37 pushes the steel balls 54 to make the elastic rods 53 rotate, and the other side of the outer wall of the steel balls 54 presses the surface of the moving block 50. By providing a support rod 51 at the center of the top of the fixed block 52, and the outer wall of the support rod 51 is in the inner wall of the moving block 50, the moving block 50, which is pressed by the steel balls 54, moves upward under the constraint of the support rod 51, and the return spring at its top moves upward. The compression force generated by the return spring 49 interacts with the tension generated by the extension rod 5 pulling the traction rope 38. At this time, the electronically controlled turntable 34 is activated, which drives the extension rod 5, the first mounting block 6, and the abrasive 8 through the fixed base 35, the fixed box 36, and the limiting plate 3 to perform uniform friction on the bottom of the textile fabric 21. During this period, because the toothed plate 14 and the fixed plate 16 are connected by the elastic plate 15 (here the elastic plate 15 is a stainless steel spring sheet that can be slightly bent by hand, which is the prior art), the continuous rotation of the extension rod 5 can easily cause the compression force of the textile fabric 21 on the abrasive 8 to become unbalanced. In this application, the abrasive 8 is kept in contact with the surface of the textile fabric 21 due to the influence of the return spring 49.At this time, the height of the fixed plate 16 is continuously and slightly controlled by the electrically controlled telescopic platform 9, causing the abrasive 8 to rub along an irregular wave trajectory on the bottom of the textile fabric 21. This further solves the problem that traditional abrasion resistance testing devices for textile fabric 21 production often use rigid friction heads for fixed force and angle friction tests, resulting in friction methods that are out of touch with actual use scenarios and thus leading to inaccurate test results.

[0046] It should be reiterated that a second motor 45 is installed at the top of the fixed base 35 near the fixed box 36, and a second transmission gear rod 46 is installed at the output end of the second motor 45. Since a lead screw 48 is installed on one side of the outer wall of the fixed box 36, and a second linkage gear rod 47 is installed at the bottom of the lead screw 48, the second transmission gear rod 46 drives the second linkage gear rod 47, causing the lead screw 48 to rotate. A U-shaped plate 44 is installed on the outer wall of the lead screw 48, and both ends of the U-shaped plate 44 are respectively located in the limiting boxes 43 installed on both sides of the outer wall of the fixed box 36. A guide groove 42 is installed on the side of the outer wall of the fixed box 36 near the limiting box 43, and both ends of the support frame 41 pass through the guide groove 42 and interact with the U-shaped plate 44. The end of the U-shaped plate 44 is connected so that when a rigid friction test is required on the textile fabric 21, the second motor 45 is started, which drives the second linkage gear rod 47 through the second transmission gear rod 46 set at the output end, causing the lead screw 48 to rotate. Thus, the lead screw 48 controls the U-shaped plate 44 and the support frame 41 to move continuously downward. During this period, the return spring 49 between the support frame 41 and the moving block 50 is continuously squeezed, so that its original elastic force is converted into rigid support force. At this time, the electric control turntable 34 drives the abrasive 8 to rub the textile fabric 21. During this period, the extension rod 5 has the characteristic of not easily rebounding, so as to prevent the abrasive 8 from pulling the textile fabric 21 off the second mounting block 19 under the continuous irregular grinding trajectory.

[0047] A method for testing the abrasion resistance of textile fabrics, the method employing the aforementioned abrasion resistance testing device for textile fabric production, as described below:

[0048] S1: By setting mutually symmetrical limiting rings 2 at one end of the top of the detection body 1, and setting limiting plate 3 on the inner wall of the limiting ring 2, by setting base 4 on the top of the limiting plate 3, and setting extension rod 5 on the inner wall of the base 4, by setting first mounting block 6 on the top of extension rod 5, abrasive 8 is wrapped around the surface of the first mounting block 6, and then the first mounting ring 7 is installed on the outer wall of the first mounting block 6 to fix the abrasive 8. By wrapping the textile fabric 21 around the bottom of the second mounting block 19, and then the second mounting ring 20 is installed on the outer wall of the second mounting block 19 to fix the textile fabric 21, and then using the fixing post 18 set at the top center of the second mounting block 19, the fixing post 18 is inserted into the mounting plate 17 to fix the second mounting block 19.

[0049] S2: When it is necessary to conduct an abrasion resistance test on the entire textile fabric 21, several mutually symmetrical control chambers 10 are set on the inner wall of the test body 1, and the transmission components set on the inner wall of the control chamber 10 are activated.

[0050] The transmission assembly controls the electrically controlled turntable 34 located at the bottom of the inner wall of the control chamber 10. The electrically controlled turntable 34 drives the extension rod 5, the first mounting block 6, and the abrasive 8 to rotate through the fixed base 35, the fixed box 36, and the limiting plate 3 to rub the bottom of the textile fabric 21. During this period, as the electrically controlled telescopic platform 9 descends, the second mounting block 19 and the textile fabric 21 apply pressure to the first mounting block 6 and the abrasive 8. As the extension rod 5 deflects as a whole, the traction rope 38 pulls the push tube 37, which, together with the steel ball 54, squeezes the moving block 50. As the moving block 50 moves upward, it applies pressure to the return spring 49, so that the rebound force of the return spring 49 and the traction force of the traction rope 38 form a relative force. This keeps the abrasive 8 in contact with the textile fabric 21, while converting the rigid friction force into elastic friction force, thereby simulating the wear of the textile fabric 21 in reality.

[0051] S3: When a radial abrasion resistance test is required, activate the elastic component to perform radial reciprocating friction on the bottom of the textile fabric 21.

[0052] The elastic component drives the first transmission gear rod 27 via the first motor 26 located on one side of the outer wall of the stabilizing chamber 11. The first transmission gear rod 27 drives the first synchronization rod 24 to rotate via the first linkage gear rods 28 located on both sides of its outer wall. Since there are two first gears 22 and two second gears 23 located on the inner wall of the stabilizing chamber 11, the two first gears 22 mesh with the two sides of the toothed plate 14 respectively, and the two second gears 23 mesh with the two sides of the toothed plate 14 respectively. The first synchronization rod 24 and the second synchronization rod 25 are respectively located at one end of the first gear 22 and the second gear 23. At the same time, the first synchronization rod 24 and the second synchronization rod 25 located on the same side of the toothed plate 14 are driven by the synchronous belt 55. Thus, the first motor 26 drives the first gears 22 and the second gears 23 to control the toothed plate 14 in the stabilizing chamber 11 to move back and forth. In conjunction with the reciprocating up and down movement of the electrically controlled telescopic table 9, the radial abrasion resistance test of the textile fabric 21 is carried out.

[0053] The working principle of the abrasion resistance testing device and testing method used in textile fabric production will be explained in detail below.

[0054] like Figures 1 to 11As shown, a plurality of mutually symmetrical limiting rings 2 are set at one end of the top of the detection body 1, and limiting discs 3 are set on the inner walls of the limiting rings 2. A base 4 is set on the top of the limiting discs 3, and an extension rod 5 is set on the inner wall of the base 4. A first mounting block 6 is set on the top of the extension rod 5, and an abrasive 8 is attached to the surface of the first mounting block 6. Then, the first mounting ring 7 is installed on the outer wall of the first mounting block 6 to fix the abrasive 8. An electrically controlled telescopic table 9 is set at the end of the top of the detection body 1 away from the limiting rings 2, and a stabilizing chamber 11 is set at the output end of the electrically controlled telescopic table 9. A toothed plate 14 is set on the inner wall of the stabilizing chamber 11, and a toothed plate 14 is set on the inner wall of the stabilizing chamber 11. An elastic plate 15 is provided at the end of plate 14, and a fixing plate 16 is provided at the top of the elastic plate 15. Since the inner cavity of the fixing plate 16 is provided with several symmetrical mounting discs 17, the cut textile fabric 21 is attached to the bottom of the second mounting block 19, and then the second mounting ring 20 is installed on the outer wall of the second mounting block 19 to fix the textile fabric 21. A fixing post 18 is provided at the center of the top of the second mounting block 19, and the second mounting block 19 with the textile fabric 21 is inserted into the mounting discs 17 sequentially through the fixing post 18 (a slot 29 is provided on the inner wall of the mounting disc 17, and the insertion tube 30 is inserted into the slot 29). The bottom of the insertion tube 30 is provided with several insertion plates 31. As the insertion tube 30 is inserted, the insertion plates 31 push the locking blocks 32 provided on the inner wall of the slot 29, so that the locking blocks 32 are embedded in the fixing post 18 under the pressure of the insertion plates 31, thereby fixing the second mounting block 19 to the bottom of the fixing plate 16. After several second mounting blocks 19 carrying textile fabric 21 are installed, the electrically controlled telescopic table 9 is activated, so that the electrically controlled telescopic table 9 drives the fixing plate 16 to move continuously downward until the surface of the textile fabric 21 contacts the surface of the abrasive 8. Several mutually symmetrical control chambers 10 are provided on the inner wall of the detection body 1, and an electrically controlled rotary valve is provided at the bottom of the inner wall of the control chamber 10. The turntable 34 is equipped with a fixed base 35 on its top, which supports the fixed box 36 located at the center of its top. When the turntable 34 is activated, it drives the extension rod 5, the first mounting block 6, and the abrasive 8 through the fixed base 35, the fixed box 36, and the limiting plate 3 to perform uniform friction on the bottom of the textile fabric 21. This further solves the problem that traditional abrasion resistance testing devices for textile fabric 21 production often use rigid friction heads for fixed force and fixed angle friction tests, which leads to friction methods that are out of touch with actual use scenarios and thus result in inaccurate test results.

[0055] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
