Description

Technical Field

[0001] This invention relates to the field of abrasion resistance testing equipment, specifically a multi-directional abrasion resistance testing device for textile fabrics. Background Technology

[0002] Wear resistance testing equipment is an indispensable precision instrument in the field of industrial production and quality inspection. It accurately evaluates the durability of materials by simulating the friction and wear scenarios that various materials may encounter in actual use.

[0003] Currently, existing abrasion testers require the sample to be cut to match the size of the sample fixture before use. The sample is then clamped and fixed. In addition, the abrasive needs to be replaced regularly. The large number of abrasives and samples tested each time means that the staff spends a lot of time installing the samples and abrasives, which greatly reduces testing efficiency.

[0004] Combining the above issues, we find that existing multi-directional abrasion resistance testing equipment for textiles on the market is difficult to simultaneously avoid the problems mentioned above. Even if it can solve them, it requires the use of external tools, thus failing to achieve the desired effect. Therefore, we propose a multi-directional abrasion resistance testing equipment for textiles. Summary of the Invention

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figures 1-4 and Figure 6 The present invention provides a technical solution: a multi-directional abrasion resistance testing device for textile fabrics, including an abrasion resistance tester 1, a testing mechanism 2 arranged above the abrasion resistance tester 1, and a replacement mechanism 3 arranged behind the abrasion resistance tester 1;

[0034] The testing unit 2 includes a quick-installation unit 21, which is located above the abrasion tester 1. The quick-installation unit 21 can quickly install the sample to be tested into a suitable position.

[0035] As a further definition of the testing mechanism 2 of the present invention, the quick installation unit 21 includes two rectangular frames 2101. The outer surface of each rectangular frame 2101 is fixedly connected to the inner wall of the wear tester 1. A fixing block 2110 is fixedly connected to the left side of each rectangular frame 2101. A rotating shaft 2111 is rotatably connected to the inner wall of each fixing block 2110. Several identical support shafts 2115 are fixedly connected to the inner bottom wall of each rectangular frame 2101. Several identical first hydraulic rods 21 are fixedly connected to the upper surface of the wear tester 1. 12. Each pair of first hydraulic rods 2112 has a lifting plate 2113 fixedly connected to its telescopic end. There are two first hydraulic rods 2112 in each pair. Several identical extrusion caps 2114 are fixedly connected to the inner wall of each lifting plate 2113. By setting up a quick installation unit 21, the sample to be tested can be quickly installed to the appropriate testing position, which greatly reduces the preparation work of the staff before testing and effectively avoids the problem of slow testing efficiency caused by the cumbersome preparation work before testing.

[0036] Please see Figure 6The wear tester 1 has two first support seats 2123 inside. Each first support seat 2123 is located below the rectangular frame 2101. The left side of each first support seat 2123 is fixedly connected to the inner side wall of the rectangular frame 2101. A first stepper motor 2122 is fixedly connected to the upper surface of each first support seat 2123. A threaded shaft 2121 is fixedly connected to the output end of each first stepper motor 2122. The outer surface of each threaded shaft 2121 is rotatably connected to the inner wall of the wear tester 1. By setting the first support seats 2123, the first support seats 2123 can provide stable support force for the first stepper motor 2122, making the first stepper motor 2122 run more stably. The power generated by the first stepper motor 2122 can drive the threaded shaft 2121 to rotate.

[0037] Please see Figure 6 The rectangular frame 2101 has several identical connecting plates 2118 slidably connected inside. Each set of connecting plates 2118 has a first roller 2117 and a second roller 2119 rotatably connected to its inner wall. There are two connecting plates 2118 in each set. Each first roller 2117 is located above the wear tester 1, and each second roller 2119 is located inside the wear tester 1. By setting the first roller 2117 and the second roller 2119, the first roller 2117 can guide the sample to be tested to move downward, so that more sample to be tested is left on the right side of the rightmost support shaft 2115. As the first stepper motor 2122 continues to run, from right to left, the second roller 2119 will drive the first roller 2117 to move downward in sequence. Thus, more sample to be tested can be left on both sides of each support shaft 2115, and the second roller 2119 can move downward under the pressure of the guide plate 2120.

[0038] Please see Figure 6Each threaded shaft 2121 has several identical guide plates 2120 threadedly connected to its outer surface. The upper surface of each guide plate 2120 contacts the bottom surface of the rectangular frame 2101. Two long plates 2109 are fixedly connected to the inner wall of the wear tester 1. Each long plate 2109 is located below the threaded shaft 2121. Several identical electromagnets 2116 are fixedly connected to the inner wall of each long plate 2109. By using the threaded connection between the threaded shaft 2121 and the guide plate 2120, the guide plate can be driven. 2120 moves to the left. It is important to understand that the upper surface of the guide plate 2120 contacts the bottom surface of the rectangular frame 2101. Therefore, the rectangular frame 2101 provides a limit to the guide plate 2120 to prevent it from rotating. At the same time, the guide plates 2120 on the threaded shaft 2121 are at different positions from the second roller 2119. The guide plate 2120 located on the far right will first contact the surface of the far right second roller 2119. The inclined surface design of the far right guide plate 2120 can push the left and right second rollers 2119 downward.

[0039] Please see Figure 1 The front of the wear tester 1 is fixedly connected to a first support plate 2103. Several identical weights 2102 are slidably connected inside the first support plate 2103. By setting the first support plate 2103 and the weights 2102, the first support plate 2103 can provide a suitable installation position for the weights 2102, and the weights 2102 can provide a certain pressure for the abrasive.

[0040] Please see Figure 2 The upper surface of the wear tester 1 is fixedly connected to two limiting shafts 2104. A disassembly plate 2106 is provided on the outer side of the two limiting shafts 2104. Two limiting holes 2107 are opened on the upper surface of the disassembly plate 2106. The outer surface of each limiting shaft 2104 is slidably connected to the inside of the limiting hole 2107. Two handles 2105 are fixedly connected to the upper surface of the disassembly plate 2106. By providing the disassembly plate 2106 and using the limiting holes 2107 opened on the upper surface of the disassembly plate 2106, it can slide on the surface of the limiting shafts 2104, providing a suitable installation position for the disassembly plate 2106 and limiting the disassembly plate 2106.

[0041] Please see Figure 2 The upper surface of the disassembly plate 2106 and the upper surface of the wear-resistant instrument 1 are provided with several identical circular holes 2108. The bottom surface of the disassembly plate 2106 is in contact with the upper surface of the wear-resistant instrument 1. The presence of the circular holes 2108 can provide an installation position for the weights 2102, allowing the weights 2102 to pass through the disassembly plate 2106 and the wear-resistant instrument 1 and connect to the installation chamber 307. Moreover, when the disassembly plate 2106 moves upward, multiple weights 2102 can be disassembled at the same time, increasing the disassembly efficiency of the weights 2102.

[0042] The specific implementation of this embodiment is as follows: When this device is needed, the sample to be tested is rolled up and placed on the surface of the rotating shaft 2111. Then, the sample is pulled to the right to unfold. The bottom surface of the unfolded sample will contact the upper surface of the support shaft 2115. Then, the first stepper motor 2122 is controlled to run. The first stepper motor 2122 generates rotational power and transmits the power to the threaded shaft 2121. Using the threaded connection between the threaded shaft 2121 and the guide plate 2120, the guide plate 2120 can be moved to the left. It should be understood that the upper surface of the guide plate 2120 is in contact with the bottom surface of the rectangular frame 2101. Therefore, the rectangular frame 2101 provides a limit to the guide plate 2120 to prevent the guide plate 2120 from rotating. Meanwhile, the guide plates 2120 on the threaded shaft 2121 are positioned differently from the second roller 2119. The rightmost guide plate 2120 will first contact the surface of the rightmost second roller 2119. The inclined surface of the rightmost guide plate 2120 can push the left and right second rollers 2119 downward. The downward movement of the second rollers 2119 will simultaneously drive the rightmost connecting plate 2118 and the first roller 2117 downward. Finally, the bottom surface of the connecting plate 2118 will contact the upper surface of the electromagnet 2116 and be attracted by the electromagnet 2116. In addition, when the first roller 2117 descends along with the second roller 2119, the first roller 2117 will push the sample to be tested above the support shaft 2115. The roller moves downwards, leaving more samples to be tested on the right side of the rightmost support shaft 2115. As the first stepper motor 2122 continues to run, from right to left, the second roller 2119 will sequentially drive the first roller 2117 downwards. This ensures that there are more samples to be tested on both sides of each support shaft 2115. Then, the first stepper motor 2122 is reset. When the first stepper motor 2122 resets, the electromagnet 2116 is de-energized, but the first roller 2117 will still provide pressure to the samples under the action of gravity. Then, the first hydraulic rod 2112 is operated. The operation of the first hydraulic rod 2112 can drive the lifting plate 2113 and the pressing cover 2114 downwards. The lifting plate 2113 will move to the rectangular frame 21. Inside 01, the bottom opening of the compression cover 2114 is slightly larger than that of the support shaft 2115. Therefore, the compression cover 2114 can compress the sample to be tested around the support shaft 2115. At this time, the sample to be tested, which was originally pressed down by the first roller 2117, will move towards the position of the support shaft 2115 and move around the support shaft 2115. At this time, the sample to be tested under the first roller 2117 will be tightened. However, the first roller 2117 is not under the magnetic force of the electromagnet 2116 at this time. Therefore, the first roller 2117 will move upward using the force generated when the sample is tightened until it contacts the bottom surface of the lifting plate 2113. Then, the upward-facing side of the first rotating gear 309 on the mounting chamber 307 can contact the surface of the sample to be tested.It's important to understand that an abrasive is installed between the first rotating gear 309 and the mounting chamber 307. This abrasive can contact the surface of the sample to be tested through a notch on the surface of the first rotating gear 309. Furthermore, the abrasive only contacts the sample to be tested at the notch in the middle of the compression cover 2114. Then, the weight 2102 is pulled out, passes through the circular hole 2108 on the surface of the disassembly plate 2106 and the abrasion tester 1, and is finally inserted into the mounting hole at the bottom of the mounting chamber 307.

[0043] Example 2: Please refer to Figures 1-4 The present invention provides a technical solution: a multi-directional abrasion resistance testing device for textile fabrics. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The testing mechanism 2 also includes a slicing unit 22, which is disposed above the abrasion tester 1. The slicing unit 22 can slice the sample after the test is completed.

[0044] As a further definition of the testing mechanism 2 of the present invention, the slicing unit 22 includes several identical second hydraulic rods 2201. The bottom end of each second hydraulic rod 2201 is fixedly connected to the upper surface of the wear tester 1. The telescopic end of each second hydraulic rod 2201 is fixedly connected to a rectangular plate 2202. A collar 2208 is fixedly connected to the outer surface of every two rectangular plates 2202. A cutting blade 2206 is provided above each collar 2208. The bottom end of each cutting blade 2206 is in contact with the bottom end of the collar 2208. Each cutting blade 2206 and collar 2208 are sleeved on the outside of the support shaft 2115. Each cutting blade 2206 has a first transmission gear 2207 fixedly connected to its outer surface. Each rectangular frame 2101 has a second support base 2205 fixedly connected to its front and back sides. Each second support base 2205 has a second stepper motor 2204 fixedly connected to its outer surface. Each second stepper motor 2204 has a second transmission gear 2203 fixedly connected to its output end. By setting up the slicing unit 22, the slicing unit 22 can be used to decide whether to slice the sample according to different needs. This not only does not lose the efficiency of the sample wear resistance test, but also allows the user to decide whether to slice the sample according to their different needs.

[0045] The specific implementation of this embodiment is as follows: When it is necessary to cut the sample for testing into circular slices, the second hydraulic rod 2201 needs to be operated. The operation of the second hydraulic rod 2201 will push the rectangular plate 2202 and the collar 2208 to move upward. When the collar 2208 moves upward, it will simultaneously drive the cutting blade 2206 to move upward. When the cutting blade 2206 moves to contact the surface of the sample to be tested, the first transmission gear 2207 fixed on the surface of the cutting blade 2206 will move to the position of meshing with the second rotating gear 302. Then, the second stepper motor 2204 is controlled to run. The operation of the second stepper motor 2204 can drive the second transmission gear 2203 fixed at its output end to rotate. Through the meshing relationship between the first transmission gear 2207 and the second transmission gear 2203, the cutting blade 2206 can be driven to rotate. The rotation of the cutting blade 2206 will cut the sample to be tested, making the sample to be tested into a circle, which is convenient for sample retention and storage.

[0046] Example 3: Please refer to Figure 7 and Figure 8 The present invention provides a technical solution: a multi-directional abrasion resistance testing device for textile fabrics. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The replacement mechanism 3 can quickly replace multiple abrasives.

[0047] As a further definition of the replacement mechanism 3 of the present invention, the replacement mechanism 3 includes a second support plate 301. The front of the second support plate 301 is fixedly connected to the back of the wear-resistant instrument 1. Several identical mounting chambers 307 are snapped into the interior of the second support plate 301. Each mounting chamber 307 has a threaded ring 308 threaded to its inner wall. A first rotating gear 309 is fixedly connected to the top of each threaded ring 308. Several identical transmission shafts 304 are rotatably connected to the inner wall of the second support plate 301. A second rotating gear 302 is fixedly connected to the top of each transmission shaft 304. The outer surface of each first rotating gear 309 meshes with the outer surface of the second rotating gear 302. Every two... A transmission gear belt assembly 306 is fixedly connected to the outer surface of the transmission shaft 304. A micro motor 303 is provided below each transmission gear belt assembly 306. The output end of each micro motor 303 is fixedly connected to the bottom end of the transmission shaft 304. A third support seat 305 is fixedly connected to the outer surface of each micro motor 303. The front of each third support seat 305 is fixedly connected to the back of the wear tester 1. By setting a replacement mechanism 3, multiple abrasives can be quickly disassembled and replaced. By setting a quick installation unit 21, a slicing unit 22, and a replacement mechanism 3, the problem of slow detection efficiency caused by cumbersome preparation work during equipment use can be effectively avoided.

[0048] The specific implementation of this embodiment is as follows: When it is necessary to replace the abrasive inside the mounting chamber 307, all mounting chambers 307 need to be disassembled, and then the mounting chambers 307 are inserted into the second support plate 301. Here, it is necessary to ensure that the first rotating gear 309 faces upwards, and the teeth on the surface of the first rotating gear 309 mesh with the teeth on the surfaces of the two adjacent second rotating gears 302. Then, the micro motor 303 is controlled to run, which drives one transmission shaft 304 to rotate. The two adjacent transmission shafts 304 are connected by a transmission gear belt assembly 306. It should be understood that the transmission gear belt assembly 306 consists of two gears and a toothed belt. Each gear is fixed to the surface of the transmission shaft 304, and the toothed belt, through the meshing of the gear surfaces, enables power transmission. Therefore... It can drive the two drive shafts 304 and the second rotating gear 302 to rotate synchronously. With the meshing relationship between the second rotating gear 302 and the first rotating gear 309, it can effectively drive the first rotating gear 309 to rotate. The threaded ring 308 fixed on the bottom surface of the first rotating gear 309 has a threaded connection with the inner wall of the mounting chamber 307. Therefore, under the action of the threaded connection, the threaded ring 308 will gradually move the first rotating gear 309 upward. At this time, the first rotating gear 309 is not in close contact with the mounting chamber 307. The inspection personnel can take out the abrasive to be replaced through the opening on the surface of the first rotating gear 309, and then put the new abrasive into the interior of the mounting chamber 307. Then, control the micro motor 303 to run in reverse, so as to achieve the purpose of fastening the first rotating gear 309 and the abrasive.
