Description

Technical Field

[0001] This application relates to the field of cashmere product testing technology, and more specifically, to a cashmere product anti-pilling testing device. Background Technology

[0002] The cashmere product anti-pilling testing device is a specialized piece of equipment designed to simulate the pilling phenomenon caused by friction and rubbing during the wearing and washing process of cashmere products. Its core function is to accelerate the pilling process through standardized mechanical friction, thereby quantitatively evaluating the anti-pilling performance of cashmere products and providing a scientific basis for quality control, process optimization, and product rating.

[0003] Chinese patent CN219475275 U discloses a cashmere sweater anti-pilling detection device. Its advantages include: a fixing mechanism that secures the cashmere sweater above the detection platform, preventing movement during pilling detection; and the ability to fix sweaters of different sizes on the platform using the fixing mechanism. The detection mechanism simulates the friction of different fabrics on the cashmere sweater in real-world conditions, allowing observation of pilling. The fixing mechanism uses a combination of clamps and sliders to hold and fix the cashmere sweater at its four corners. The following issues arise: First, insufficient precision in clamping force control can easily cause physical damage to cashmere fibers. Since the breaking strength of cashmere fibers is only 0.5-1.5 cN / dtex, if traditional mechanical clamps apply a clamping force exceeding 8N, it may directly lead to fiber breakage or fabric structure damage, causing the pilling grade of worsted cashmere sweaters to be artificially inflated by 1-2 grades due to fiber damage. Second, uneven distribution of clamping force can create stress concentration areas at the edges, causing localized wrinkling and deformation, and compromising the uniformity of friction testing. Third, insufficient clamp fit can lead to sample distortion or detachment, affecting the representativeness of the test results and the versatility of the equipment. Utility Model Content

[0005] To achieve the above objectives, this application provides the following technical solution: a cashmere product anti-pilling testing device, comprising a testing platform, wherein two fixing slots are opened inside the testing platform, and a second set of blocks is movably installed inside each fixing slot. The two second sets of blocks are threaded together with the same bidirectional screw, and the bidirectional screw passes through the testing platform.

A pull rod is fixedly installed on the top of the limiting plate, and one end of the pull rod passes through the top of the limiting frame.

[0007] As a preferred technical solution of this application, there are multiple telescopic rods, which are evenly distributed on both sides of the pull rod.

[0008] As a preferred technical solution of this application, each limiting frame has multiple grooves on its inner bottom wall, and each limiting plate has multiple protrusions on its outer bottom wall corresponding to the multiple grooves.

[0009] As a preferred technical solution of this application, a fixed frame is movably installed on the detection platform.

[0016] 1. This application utilizes a telescopic rod, spring, limiting plate, and pull rod to facilitate the limiting and fixing of both ends of the cashmere product. The cooperation between the bidirectional screw and the second set of blocks facilitates the tensioning of the cashmere product, improving the testing effect. The limiting and fixing ensures that the cashmere product is stable in position during testing, avoiding shaking or displacement that could interfere with the accuracy of the test. The tensioning process flattens the product surface, ensuring even stress distribution to restore the tensile state during actual use and prevent abnormal friction caused by localized looseness, thus facilitating the presentation of the product's anti-pilling performance. At the same time, the limiting and fixing helps the testing personnel quickly position the product, shortening the clamping time.

This application uses the first set of blocks and the first set of blocks to drive the fixed frame and friction column to move linearly, so that the friction column makes regular linear reciprocating motion on the surface of cashmere products, ensuring uniform distribution of friction force, avoiding edge effect caused by centrifugal force generated by rotation, and making the test results more realistically reflect the anti-pilling performance.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0028] like Figures 1 to 7 As shown, the anti-pilling testing device for cashmere products provided in this application includes a testing platform 1. The testing platform 1 has two fixing slots 18 inside. A second sleeve block 16 is movably installed inside each fixing slot 18. The two second sleeve blocks 16 are threaded with the same bidirectional screw 15, and the bidirectional screw 15 passes through the testing platform 1. A driven gear 17 is fixedly installed at one end of the bidirectional screw 15. A second motor 20 is fixedly installed on one side of the testing platform 1. A drive gear 19 is fixedly installed at the output end of the second motor 20, and the drive gear 19 is movably installed on one side of the testing platform. The drive gear 19 meshes with the driven gear 17.

[0029] The second block 16 has a fixed limit frame 22 installed on its top. A limit plate 24 is movably installed inside the limit frame 22. A telescopic rod 27 is fixedly installed between the limit plate 24 and the limit frame 22. A pull rod 23 is fixedly installed on the top of the limit plate 24, and one end of the pull rod 23 passes through the top of the limit frame 22. A spring 28 is fixedly installed between the limit frame 22 and the limit plate 24 and is sleeved on the telescopic rod 27.

[0030] The worker holds the lever 23, which moves upward within the limiting plate 24 and the limiting frame 22. The limiting plate 24 compresses the telescopic rod 27 and the spring 28. When the limiting plate 24 disengages from the bottom of the limiting frame 22, one end of the cashmere product is slowly inserted into the limiting frame 22. Then, the lever 23 is released, and the telescopic rod 27 and spring 28 compress the limiting plate 24, causing it to quickly enter the limiting frame 22 and secure the cashmere product. The other end of the cashmere product is secured in the same way. To tension the cashmere product, the second motor 20 is activated, driving the drive gear 19 to rotate. The drive gear 19 then rotates the driven gear 17, which in turn rotates the bidirectional screw 15 inside the second set of blocks 16. This causes the two second sets of blocks 16 to move outwards within the fixing groove 18. The second sets of blocks 16 then move the limiting frame 22 synchronously, pulling the cashmere product to tension. This completes the limiting and fixing of the cashmere product within the limiting frame 22. Each fixing groove 18 has slide rails on both sides, and the second sets of blocks 16 have corresponding sliders on their respective sides. These sliders are slidably connected within the slide rails, allowing the second sets of blocks 16 to move smoothly within the fixing groove 18.

[0031] The operator holds the adjusting lever 23 and pulls it upward within the limiting frame 22. This causes the limiting plate 24 to compress the telescopic rod 27 and the spring 28. Once the sliding limit plate 24 is completely disengaged from the bottom of the sleeve limiting frame 22, one end of the cashmere product is slowly placed into the clamping area of ​​the limiting frame 22. The lever 23 is then released, and the restoring force of the telescopic rod 27 pushes the limiting plate 24 back to its original position. The bottom of the limiting plate 24 then provides more accurate positioning and fixation of the cashmere product. The same steps are used to fix the other end of the product. Then, the second drive motor 20 is started. Through the meshing of the drive gear 19 and the driven gear 17, torque is transmitted to the bidirectional screw 15. As the bidirectional screw 15 rotates within the second sleeve block 16, it drives the two second sleeve blocks 16 to move synchronously outward along the guide rail fixing groove 18, thereby causing the limiting frame 22 to stretch in the opposite direction, creating uniform tension on the surface of the cashmere product. This process is achieved through mechanical linkage. The coordinated control of limiting fixation and tension adjustment ensures that the test area is flat and wrinkle-free, providing a stable foundation for the subsequent reciprocating motion test of the friction column 4, so as to finally complete the evaluation of the anti-pilling performance of cashmere products. The device facilitates the limiting fixation of both ends of the cashmere product through the telescopic rod 27, spring 28, limiting plate 24 and pull rod 23. The cooperation between the bidirectional screw 15 and the second set of blocks 16 facilitates the tensioning of the cashmere product, improving the detection effect. Limiting fixation ensures that the cashmere product is stable in position during testing, avoiding shaking and displacement that interfere with the accuracy of testing. Tensioning treatment flattens the product surface, making it evenly stressed, so as to restore the tensile state during actual use, avoiding abnormal friction caused by local relaxation, and making it easier to present the anti-pilling performance of the product. At the same time, limiting fixation helps the tester to quickly position the product, shortening the clamping time. The tensioned product is stable without displacement or wrinkles during testing, reducing test interruptions and repetitive operations, and improving testing efficiency.

[0032] There are multiple telescopic rods 27, which are evenly distributed on both sides of the pull rod 23.

[0033] The diagram shows four telescopic rods 27 as an example. Two telescopic rods 27 are located on one side of the pull rod 23, and the other two telescopic rods 27 are located on the other side of the pull rod 23. This facilitates stable support for the limiting frame 22, ensuring the stability of the limiting frame 22 during use. Furthermore, the multiple telescopic rods 27 and multiple springs 28 compress the limiting plate 24, enabling the limiting plate 24 to more firmly limit the cashmere products entering the limiting frame 22.

[0034] Each limiting frame 22 has multiple grooves 32 on its inner bottom wall, and each limiting plate 24 has multiple protrusions 31 on its outer bottom wall corresponding to the multiple grooves 32.

[0035] After slowly inserting one end of the cashmere product into the limiting frame 22, release the pull rod 23. The telescopic rod 27 and spring 28 will press the limiting plate 24, causing the limiting plate 24 to move downward and limit and fix the cashmere product inside the limiting frame 22. At the same time, multiple protrusions at the bottom of the limiting plate 24 will hold the cashmere product into multiple grooves in the limiting frame 22, further strengthening the limiting and fixing effect on the cashmere product inside the limiting frame 22.

[0036] Among them, a fixed frame 2 is movably installed on the testing platform 1. A movable block 29 and a second cylinder 30 are movably installed inside the top of the fixed frame 2. The second cylinder 30 is fixedly connected to the movable block 29. A first cylinder 3 is fixedly installed at the bottom of the movable block 29. A fixed frame 5 is fixedly installed at the bottom of the first cylinder 3. A first motor 14 is fixedly installed inside the fixed frame 5. A friction column 4 is fixedly installed at the output end of the first motor 14.

[0037] After the staff has positioned the cashmere product, the second cylinder 30 pushes the moving block 29 and the first cylinder 3 to the preset detection position inside the fixed frame 2. Then, the first cylinder 3 pushes the fixed frame 5 and the first motor 14 to slowly descend. The friction column 4 is slowly lowered to the top of the cashmere product through the cooperation between the first motor 14 and the fixed frame 5. At the same time, the third motor 25 and the first motor 14 are turned on. The first motor 14 drives the friction column 4 to rotate on the top of the cashmere product, rubbing the cashmere product and observing the pilling of the cashmere sweater. Thus, the detection of the cashmere product is completed through the friction column 4.

[0038] The detection platform 1 has a sliding groove 8 on one side, a first sleeve block 6 is movably installed inside the sliding groove 8, a screw rod 7 is threaded inside the first sleeve block 6, a third motor 25 is fixedly installed on one side of the detection platform 1, and the output end of the third motor 25 is fixedly connected to the screw rod 7, and the fixing frame 2 is fixedly installed on the top of the first sleeve block 6.

[0039] During the testing process, the screw 7 is driven by the third motor 25 to rotate within the first set of blocks 6, causing the first set of blocks 6 to move horizontally along the slide groove 8. The friction column 4 is pulled by the fixed frame 2 to achieve a reciprocating trajectory motion. This device uses the first set of blocks 6 to drive the fixed frame 2 and the friction column 4 to move linearly, ensuring that the friction column 4 performs regular linear reciprocating motion on the surface of the cashmere product. This ensures uniform distribution of friction force and avoids edge effects caused by centrifugal force generated by rotation, making the test results more accurately reflect the anti-pilling performance. The slide groove 8 has slideways on both sides, and the first set of blocks 6 has sliders on its corresponding sides. The sliders are slidably connected within the slideways, allowing the first set of blocks 6 to move smoothly within the slide groove 8.

[0040] Two support bases 21 are fixedly installed on one side of the testing platform 1. The two support bases 21 are used to install the second motor 20 and the third motor 25, respectively. This facilitates the provision of stable support for the second motor 20 and the third motor 25, ensuring the stability of the second motor 20 and the third motor 25 during use.

[0041] Among them, support plates 9 are vertically fixedly installed on both sides of the bottom of the testing platform 1, and a fixing plate 10 is horizontally fixedly installed between the two support plates 9.

[0042] Since a fixing plate 10 is fixedly installed between the two support plates 9, the cooperation between the support plates 9 and the fixing plate 10 facilitates stable support for the testing platform 1, reduces shaking of the testing platform 1 during use, and improves the utilization efficiency of the testing platform 1.

[0043] A reinforcing rib 26 is fixedly installed at the angle between the support plate 9 and the fixing plate 10, and the reinforcing rib 26 is triangular in shape.

[0044] Since the reinforcing rib 26 is triangular in shape at the angle between the support plate 9 and the fixing plate 10, and triangles have the characteristic of stability, the stability of the support plate 9 and the fixing plate 10 is ensured during use, and the efficiency of the support plate 9 and the fixing plate 10 is improved.

[0045] Among them, a fixing seat 11 is fixedly installed on the outer side of the support plate 9, and a fixing block 12 is movably installed inside the fixing seat 11, and a work box 13 is fixedly installed on the back of the fixing block 12.

[0046] The work box 13 makes it easy for workers to retrieve the workpieces needed during the work process from inside the work box 13.

[0047] The working principle and usage process of this application:

[0048] The worker pulls the limiting plate 24 upward inside the limiting frame 22 by pulling the lever 23. The limiting plate 24 compresses the telescopic rod 27 and the spring 28. When the limiting plate 24 disengages from the bottom of the limiting frame 22, one end of the cashmere product is slowly placed into the limiting frame 22. Then, the lever 23 is released, and the telescopic rod 27 and the spring 28 compress the limiting plate 24. The protrusion 31 at the bottom of the limiting plate 24 slowly enters the groove 32, allowing the protrusion 31 to quickly limit and fix the cashmere product inside the groove 32. The same method is used to place the cashmere product in the other end... One end is also fixed. Next, the cashmere product needs to be tensioned. The second motor 20 is turned on, which drives the drive gear 19 to rotate. The drive gear 19 drives the driven gear 17 to rotate, and the driven gear 17 drives the bidirectional screw 15 to rotate inside the second block 16. This causes the two second blocks 16 to move outward in the fixing groove 18. The second blocks 16 drive the limiting frame 22 to move synchronously. The limiting frame 22 pulls the cashmere product to be tensioned, thereby completing the limiting and fixing of the cashmere product inside the limiting frame 22.

[0049] After the staff has positioned the cashmere product, the second cylinder 30 pushes the moving block 29 and the first cylinder 3 to a suitable distance inside the fixed frame 2. Then, the first cylinder 3 pushes the fixed frame 5 and the first motor 14 to slowly descend, bringing the friction column 4 down to contact the top of the cashmere product. At the same time, the first motor 14 drives the friction column 4 to rotate, rubbing the cashmere product and observing the pilling. The third motor 25 drives the screw 7 to rotate inside the first set of blocks 6, causing the first set of blocks 6 to move synchronously inside the slide groove 8, which in turn moves the friction column 4, thus completing the inspection of the cashmere product through the friction column 4.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
