Description

Technical Field

[0001] This utility model relates to the field of fabric testing technology, specifically a fabric abrasion resistance testing device. Background Technology

[0002] As is well known, the original meaning of textiles comes from the general term for spinning and weaving. However, with the continuous development and improvement of the textile knowledge system and discipline system, especially after the emergence of technologies such as nonwoven textile materials and three-dimensional composite weaving, it is no longer just about traditional hand spinning and weaving. It also includes nonwoven fabric technology, modern three-dimensional weaving technology, modern electrostatic nano-web forming technology, etc., to produce clothing, industrial and decorative textiles. Therefore, modern textiles refer to a multi-scale structural processing technology of fibers or fiber assemblies. After the fabric is made into clothing, areas such as the inner sides of the arms and legs are subject to more friction. Therefore, it is necessary to use fabrics with a certain abrasion resistance. During the fabric processing, friction testing is usually performed on the fabric.

[0003] Therefore, Chinese Patent Publication No. CN 222850450 U proposes a fabric abrasion resistance testing device, which can perform tests on the same fabric under different pressures and friction levels, reducing fabric waste and facilitating comparison by testing personnel. The device includes an operating table with a support frame, on which a drive motor is fixedly mounted. A turntable is mounted on the rotating end of the drive motor. A testing platform aligned vertically with the turntable is mounted on the operating table, and a collar is installed on the testing platform. The turntable has multiple mounting through holes, each with a different distance from the midpoint of the turntable. A connecting rod is slidably mounted inside each mounting through hole, and a mounting plate is fixedly mounted at the bottom of the connecting rod. A friction plate is detachably mounted on the bottom of the mounting plate, and a counterweight is detachably mounted on the top of the connecting rod. The counterweight is equipped with various weights and friction plates with different friction forces.

[0004] However, the fabric abrasion resistance testing device has a single motion mode during use, which cannot simulate the complex wear conditions that the fabric experiences in actual use scenarios. This causes the test data to be out of touch with the actual application scenario, resulting in the test results not being able to truly reflect the abrasion resistance performance of the fabric in actual use. At the same time, the fabric is not stable enough in terms of fixing, and the fabric is prone to displacement during the test, which further affects the accuracy of the test results, thus causing defects in the use of the device. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4This utility model provides a technical solution: a fabric abrasion resistance testing device, including a base 1, a support frame 2 symmetrically fixedly connected to the top of the base 1, a first clamping plate 22 fixedly connected inside the support frame 2, and a second clamping plate 23 slidably connected inside the support frame 2 for fixing fabrics of different thicknesses, a first support plate 5 fixedly connected to the top of the base 1, and a second support plate 6 fixedly connected to the end of the top of the base 1 away from the first support plate 5, a rotating shaft 7 rotatably connected between the first support plate 5 and the second support plate 6, and a first connecting plate 8 fixedly connected to the outer side of the rotating shaft 7. The first connecting plate 8 is rotated by the motor. A friction block 10 is detachably connected inside the first connecting plate 8. The friction block 10 can be replaced as needed for testing. Threaded holes 12 are provided on both sides of the friction block 10. Connecting holes 9 are provided on both sides of the first connecting plate 8. The connecting holes 9, threaded holes 12 and bolts 11 are used together. The bolts 11 pass through the connecting holes 9 on the surface of the first connecting plate 8 and are threadedly connected to the threaded holes 12 on the surface of the friction block 10. There are multiple connecting holes 9, which can adjust the height of the friction block 10 and adjust the pressure between the friction block 10 and the fabric as needed for testing.

[0026] Furthermore, one end of the rotating shaft 7 passes through one side of the second support plate 6 and is fixedly connected to a driven gear 20. The driven gear 20 rotates, causing the rotating shaft 7 to rotate.

[0027] Furthermore, a fixing frame 21 is fixedly connected to the top of the base 1, and a second connecting plate 17 is rotatably connected to one side of the fixing frame 21. A sector gear 19 is fixedly connected to one side of the second connecting plate 17. The second connecting plate 17 rotates, causing the sector gear 19 to rotate. One side of the sector gear 19 meshes with the driven gear 20, and the sector gear 19 rotates, causing the driven gear 20 to rotate.

[0028] Furthermore, a third support plate 13 is fixedly connected to the top of the base 1, and an eccentric wheel 15 is rotatably connected to one side of the third support plate 13. A connecting column 16 is fixedly connected to one end of the eccentric wheel 15, and the eccentric wheel 15 rotates, causing the connecting column 16 to rotate.

[0029] Furthermore, a groove 18 penetrating its surface is provided on one side of the second connecting plate 17, so that the outer side of the connecting column 16 is slidably connected to the groove 18, and the connecting column 16 rotates through the groove 18 to make the second connecting plate 17 swing back and forth.

[0030] Furthermore, a motor 14 is fixedly connected to one side of the third support plate 13. The output end of the motor 14 passes through one side of the third support plate 13 and is fixedly connected to the eccentric wheel 15. After the motor 14 is turned on, it drives the eccentric wheel 15 to rotate.

[0031] Furthermore, a connecting frame 3 is slidably connected inside the support frame 2, and a threaded rod 4 is rotatably connected to the top of the support frame 2. The outer side of the threaded rod 4 is threadedly connected to the connecting frame 3, and the rotation of the threaded rod 4 causes the connecting frame 3 to move up and down.

[0032] Furthermore, the bottom of the connecting frame 3 is fixedly connected to the second clamping plate 23. The connecting frame 3 moves, causing the second clamping plate 23 to move as well, to fix fabrics of different thicknesses.

[0033] In use, the fabric is placed between the first clamping plate 22 and the second clamping plate 23. Rotating the threaded rod 4 causes the second clamping plate 23 to slide up and down via the connecting bracket 3, thereby adjusting the clamping plate spacing and clamping fabrics of different thicknesses. The first connecting plate 8 is connected to the friction block 10 via bolts 11. The threaded holes 12 on both sides of the friction block 10 are aligned with the connecting holes 9 on the connecting plate. The bolts 11 are then passed through the connecting holes 9 and connected to the threaded holes 12. Friction blocks 10 of different materials or shapes can be replaced according to testing requirements, and the height of the friction blocks 10 can also be adjusted to regulate friction. The pressure between the friction block 10 and the fabric is generated by the motor 14 driving the eccentric wheel 15 to rotate. The eccentric wheel 15 slides and engages with the groove 18 of the second connecting plate 17 through the connecting column 16. The eccentric movement of the eccentric wheel 15 causes the second connecting plate 17 to swing back and forth, which in turn drives the sector gear 19 on one side to swing. The swing of the sector gear 19 causes the driven gear 20 to rotate back and forth, thereby driving the rotating shaft 7 and the first connecting plate 8 to rotate back and forth. When the friction block 10 rotates with the first connecting plate 8, its surface contacts the clamped fabric and generates friction, simulating the wear scenario in actual use.
