Description

Technical Field

[0001] This invention relates to the field of fabric testing, and in particular to a device for testing the impact and abrasion performance of clothing fabrics. Background Technology

[0002] The impact and abrasion performance testing device for clothing fabrics is a specialized testing equipment for evaluating the impact resistance and abrasion resistance of clothing fabrics. Its core purpose is to simulate the actual working conditions that fabrics may encounter during daily wear, special operations, or outdoor use, such as impact collisions, friction, and scratches. It accurately measures the changes in mechanical properties, surface damage, and service life threshold of the fabric under repeated impact loads and continuous abrasion. It can provide data support for the research and development of clothing fabrics, helping researchers optimize fiber ratios, weaving processes, and finishing technologies. It can also provide objective standards for incoming material inspection and finished product acceptance for clothing manufacturers, ensuring the durability and wearing stability of clothing products. At the same time, it can also meet the performance certification requirements of protective clothing in special fields such as fire protection, construction, and outdoor sports, ensuring that the fabric can effectively play a protective role in complex environments and reducing safety hazards caused by fabric damage and failure. However, traditional methods often use friction structures with fixed angles, which cannot be adapted to the force angles of different parts of the garment. This is because traditional devices are not designed with a precisely positioned angle adjustment mechanism, which means they can only simulate the friction state under a single fixed angle. This is seriously out of touch with the dynamic angle changes of the fabric attached to different parts of the body during movement, and cannot fully cover the diverse friction scenarios in actual wear. As a result, the detection range is narrow, and the data has limited reference value for garment fabric selection and performance optimization, making it difficult to accurately guide actual production applications.

[0003] Therefore, the present invention provides a device for testing the impact and abrasion performance of clothing fabrics. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: A device for testing the impact and abrasion performance of clothing fabrics includes a base, the surface of which is provided with a groove, and a positioning mechanism is provided at the upper end of the base. The positioning mechanism includes a slide table slidably connected to a base via a sliding groove. A turntable is rotatably connected to the upper end of the slide table. A first guide rod is slidably connected inside the turntable. A positioning tooth block is fixedly connected to the side end of the first guide rod. The surface of the positioning tooth block meshes with the turntable. A first spring is fixedly connected inside the turntable. A rotating plate is fixedly connected to the end of the first spring. The side end of the rotating plate is rotatably connected to the positioning tooth block. A fixing block is rotatably connected to the surface of the first guide rod. The surface of the fixing block is threadedly connected to the slide table. A rotating handle is fixedly connected to the side end of the fixing block. After the turntable rotates, its angle is positioned by the positioning tooth block, thereby breaking through the limitations of traditional fixed friction angles and accurately matching the force angle of clothing fabric during actual wear. It is suitable for wear detection of fabrics in different wearing parts, simulating the friction state between the fabric and the outside world during human activity, and improving the detection range and data applicability of the device for fabric wear.

[0007] In a preferred embodiment, the upper end of the positioning plate is provided with a positioning hole, and the upper end of the turntable is fixedly connected with a positioning bolt. The surface of the positioning bolt is slidably connected to the positioning plate through the positioning hole.

[0008] The technical effect of adopting the above-mentioned further solution is that the positioning plate can be quickly fixed by sliding the positioning bolt and the positioning hole.

[0009] In a preferred embodiment, a first motor is fixedly connected inside the base, and a reciprocating lead screw is fixedly connected to the output end of the first motor. The surface of the reciprocating lead screw is threadedly connected to the slide table. A limit rod is fixedly connected inside the base, and the surface of the limit rod is slidably connected to the slide table. A support wheel is rotatably connected to the bottom of the slide table, and the surface of the support wheel is in contact with the base.

[0010] The technical effect of adopting the above-mentioned further solution is that by driving the reciprocating lead screw to rotate by the first motor, the relative reciprocating motion between the fabric and the wear mechanism can be realized, which can simulate the dynamic friction process of the fabric during human activities, thereby improving detection efficiency and reducing operational intensity.

[0011] In a preferred embodiment, the surface of the base is provided with a lifting mechanism, the lifting mechanism including a lifting bracket fixedly connected to the surface of the base, a lifting platform slidably connected inside the lifting bracket, a curtain provided on the surface of the lifting bracket, a second motor fixedly connected inside the lifting bracket, a lifting rod fixedly connected to the output end of the second motor, and the surface of the lifting rod threadedly connected to the lifting platform.

[0012] The technical effect of adopting the above-mentioned further solution is that the second motor drives the lifting rod to rotate, thereby driving the lifting platform to rise and fall smoothly along the lifting support, providing an appropriate height for impact and wear testing of different intensities.

[0013] In a preferred embodiment, the side end of the lifting bracket is provided with a wear mechanism. The wear mechanism includes a support platform disposed at the lower end of the lifting platform, a slide rod fixedly connected to the upper end of the base, the surface of the slide rod being slidably connected to the support platform, a mounting bracket fixedly connected to the upper end of the support platform, a weight slidably connected to the surface of the mounting bracket, and a mounting platform fixedly connected to the lower end of the support platform. The inner wall of the mounting platform is provided with a grinding tool.

[0014] The technical effect of adopting the above-mentioned further solution is that: by installing the bracket, a stable mounting and sliding foundation is provided for the weight, and the friction phenomenon under different pressures is detected according to the number of weights, thereby improving the applicability of the device.

[0015] In a preferred embodiment, the mounting bracket has a positioning groove on its surface, and a fixing sleeve is slidably connected to the mounting bracket through the positioning groove. Two push plates are slidably connected inside the fixing sleeve, and an inclined block is fixedly connected to the side end of each push plate. The side end of the inclined block is slidably connected to the mounting bracket. A second spring is fixedly connected between the two push plates, and a second guide rod is fixedly connected inside the fixing sleeve. The surface of the second guide rod is slidably connected to the push plate.

[0016] The technical effect of adopting the above-mentioned further solution is that by setting the inclined block, when the fixed sleeve is inserted into the positioning groove, the inclined block is squeezed and retracted into the fixed sleeve, and when the squeezing is removed, it opens under the action of the second spring, thereby positioning the weight, reducing the operation time of changing the number of weights when the device simulates different pressures, and improving the detection efficiency of the device.

[0017] In a preferred embodiment, the side end of the lifting bracket is provided with an impact mechanism, the impact mechanism includes a third motor fixedly connected to the surface of the lifting platform, a rotating rod rotatably connected to the lower end of the lifting platform, the output end of the third motor being fixedly connected to the rotating rod, a pull block being fixedly connected to the end of the rotating rod, and a pull groove being provided at the upper end of the mounting bracket, the pull block being slidably connected to the mounting bracket through the pull groove.

[0018] The technical effect of adopting the above-mentioned further solution is that: by pulling the block to lift the fabric during the installation of the positioning mechanism to avoid obstructing the installation, and then rotating to release the installation bracket after lifting it, the friction state of the fabric under different impact conditions can be simulated by the free-falling abrasive and the adjustable angle of the turntable. It is suitable for outdoor sports environments such as sportswear and mountaineering clothing. The abrasion resistance of the fabric when it falls accidentally can be used to study the failure mechanism of the fabric under dynamic composite stress, and provide experimental basis for the development of impact-resistant and abrasion-resistant fabrics.

[0019] This invention provides a device for testing the impact and abrasion performance of clothing fabrics. It has the following beneficial effects: The angle of the positioning teeth is determined by the rotation of the turntable, which accurately matches the force angle of the clothing fabric in actual wear. It is suitable for wear detection of fabrics in different wearing parts, simulates the friction state between the fabric attached to different parts of the human body and the outside world, and improves the detection range and applicability of the fabric wear of the device.

[0020] By setting an inclined block, when the fixed sleeve is inserted into the positioning groove, the inclined block is squeezed and retracts into the fixed sleeve. When the squeezing is released, it opens under the action of the second spring, thereby positioning the weight. This reduces the time required to change the number of weights when the device simulates different weights and improves the detection efficiency of the device.

[0021] By lifting the support platform with a pull block and then rotating it to release it, the friction state of the fabric under different impact conditions can be simulated using a free-falling abrasive with an adjustable turntable angle. This is suitable for outdoor sports environments such as sportswear and mountaineering clothing. The abrasion resistance of the fabric when it falls accidentally can be used to study the failure mechanism of the fabric under dynamic composite stress, providing experimental basis for the development of impact-resistant and abrasion-resistant fabrics.

[0024] 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. Example

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the present invention provides a device for testing the impact and abrasion performance of clothing fabrics, including a base 1, a groove 2 on the surface of the base 1, and a positioning mechanism 3 at the upper end of the base 1. The positioning mechanism 3 includes a slide table 301 slidably connected to the base 1 via a slide groove 2. The slide groove 2 is adapted to the slide table 301. A turntable 302 is rotatably connected to the upper end of the slide table 301. The inner circumference of the slide table 301 is equal to the outer circumference of the turntable 302. A first guide rod 303 is slidably connected inside the turntable 302. The inner circumference of the turntable 302 is equal to the outer circumference of the first guide rod 303. A positioning tooth block 304 is fixedly connected to the side end of the first guide rod 303. A toothed groove is formed on the side of the turntable 302 corresponding to the positioning tooth block 304. The surface of the positioning tooth block 304 meshes with the turntable 302. The positioning tooth block 304 is adapted to the toothed groove formed on the turntable 302. A first spring 305 is fixedly connected inside the turntable 302. A rotating plate 30 is fixedly connected to the end of the first spring 305. 6. The side end of the rotating plate 306 is rotatably connected to the positioning tooth block 304. The rotating plate 306 and the positioning tooth block 304 are adapted to each other. The surface of the first guide rod 303 is rotatably connected to the fixing block 307. The first guide rod 303 and the fixing block 307 are adapted to each other. The surface of the fixing block 307 is threadedly connected to the slide table 301. The fixing block 307 and the slide table 301 are adapted to each other. The side end of the fixing block 307 is fixedly connected to the rotating handle 308. After the turntable 302 rotates, its angle is positioned by the positioning tooth block 304, thereby breaking through the limitations of the traditional fixed friction angle, accurately matching the force angle of the clothing fabric in actual wear, and is suitable for wear detection of fabrics in different wearing parts. It simulates the friction state between the fabric and the outside world when the human body is active, and improves the detection range and data applicability of the fabric wear detection device.

[0026] like Figure 4 As shown: A support platform 309 is fixedly connected to the upper end of the turntable 302, and a positioning plate 310 is slidably connected to the upper end of the turntable 302. An extrusion plate 311 is fixedly connected to the lower end of the positioning plate 310. The extrusion plate 311 has a structure that is wider at the top and narrower at the bottom, and its surface is covered with a rubber layer. The support platform 309 is used to support and place the fabric. With the positioning plate 310 driving the extrusion plate 311 to slide, the garment fabric on the support platform 309 can be quickly pressed and positioned, preventing the fabric from shifting during the inspection process, ensuring the stability of the wear detection process, and thus improving the accuracy of the detection data.

[0027] like Figure 4 As shown: The upper end of the positioning plate 310 is provided with a positioning hole 312, and the upper end of the turntable 302 is fixedly connected with a positioning bolt 313. The surface of the positioning bolt 313 is slidably connected to the positioning plate 310 through the positioning hole 312. The positioning bolt 313 and the positioning hole 312 are adapted to each other. Through the cooperation and sliding of the positioning bolt 313 and the positioning hole 312, the sliding trajectory of the positioning plate 310 can be precisely limited to ensure that the pressing force of the extrusion plate 311 on the fabric is evenly distributed.

[0028] like Figure 3As shown: A first motor 314 is fixedly connected inside the base 1. A reciprocating lead screw 315 is fixedly connected to the output end of the first motor 314. The surface of the reciprocating lead screw 315 is threadedly connected to the slide table 301. The reciprocating lead screw 315 and the slide table 301 are adapted to each other. A limit rod 316 is fixedly connected inside the base 1. The surface of the limit rod 316 is slidably connected to the slide table 301. A support wheel 317 is rotatably connected to the bottom of the slide table 301. The limit rod 316 and the support wheel 317 are adapted to each other. The surface of the support wheel 317 is in contact with the base 1. The support wheel 317 provides support for the movement of the slide table 301. The first motor 314 drives the reciprocating lead screw 315 to rotate, causing the slide table 301 to slide smoothly along the limit rod 316. The support wheel 317 can reduce the friction force when the slide table 301 slides, realize the relative reciprocating motion between the fabric and the wear mechanism, and simulate the dynamic friction process of the fabric during human activity, thereby improving detection efficiency and reducing operational intensity.

[0029] like Figure 5 As shown: A lifting mechanism 4 is provided on the surface of the base 1. The lifting mechanism 4 includes a lifting bracket 401 fixedly connected to the surface of the base 1. A lifting platform 402 is slidably connected inside the lifting bracket 401. The lifting platform 402 slides on the lifting bracket 401 to change its height. A curtain 403 is provided on the surface of the lifting bracket 401. A second motor 404 is fixedly connected inside the lifting bracket 401. A lifting rod 405 is fixedly connected to the output end of the second motor 404, providing power support. The surface of the lifting rod 405 is threadedly connected to the lifting platform 402. The lifting rod 405 and the lifting platform 402 are adapted to each other. The second motor 404 drives the lifting rod 405 to rotate, causing the lifting platform 402 to rise and fall smoothly along the lifting bracket 401. This allows for precise adjustment of the distance between the wear mechanism, the impact mechanism, and the fabric, providing an appropriate height for impact and wear testing of different intensities. The curtain 403 protects the internal structure of the lifting mechanism, preventing debris and dust from entering during the testing process and affecting the transmission stability, while also ensuring operational safety.

[0030] like Figure 6As shown: A wear mechanism 5 is provided on the side end of the lifting bracket 401. The wear mechanism 5 includes a support platform 501 located at the lower end of the lifting platform 402. A slide rod 502 is fixedly connected to the upper end of the base 1. The surface of the slide rod 502 is slidably connected to the support platform 501. The outer circumference of the slide rod 502 is equal to the inner circumference of the support platform 501. A mounting bracket 503 is fixedly connected to the upper end of the support platform 501. A weight 504 is slidably connected to the surface of the mounting bracket 503. The mounting bracket 503 and the weight 504 are adapted to each other, thereby limiting the horizontal movement of the weight 504. The lower end of the support platform 501 is fixedly connected to the mounting platform 505. The inner wall of the mounting platform 505 is provided with a grinding mold 506. The support platform 501 is slidably limited by the sliding rod 502 to ensure that the grinding mold 506 moves smoothly during the wear process. The mounting bracket 503 provides a stable mounting and sliding base for the weight 504 and detects the friction phenomenon under different pressures according to the number of weights. The grinding mold 506 can be replaced with different materials and roughness types according to the detection requirements to adapt to the simulation detection of different wear scenarios and improve the applicability of the device.

[0031] like Figure 6 - Figure 7 As shown: The surface of the mounting bracket 503 has a positioning groove 507. A fixing sleeve 508 is slidably connected to the mounting bracket 503 through the positioning groove 507. Each number of weights 504 corresponds to a different positioning groove 507. Inserting the fixing sleeve 508 prevents the weights 504 from swaying up and down when the support platform 501 falls. Two push plates 509 are slidably connected inside the fixing sleeve 508. An inclined block 510 is fixedly connected to the side end of each push plate 509. The side end of the inclined block 510 is inclined. When compressed, the two inclined blocks 510 move inwards. The side end of the inclined block 510 is slidably connected to the mounting bracket 503. The two push plates 509... A second spring 511 is fixedly connected between the fixed sleeve 508 and the push plate 509. A second guide rod 512 is fixedly connected inside the fixed sleeve 508. The surface of the second guide rod 512 is slidably connected to the push plate 509. The outer circumference of the second guide rod 512 is equal to the inner circumference of the push plate 509. By setting the inclined block 510, when the fixed sleeve 508 is inserted into the positioning groove 507, the inclined block 510 is squeezed and retracted into the fixed sleeve 508. When the squeezing is removed, it opens under the action of the second spring 511, thereby positioning the weight 504. This reduces the time required to change the number of weights 504 when the device simulates different weights, and improves the detection efficiency of the device.

[0032] like Figure 6As shown: An impact mechanism 6 is provided on the side end of the lifting bracket 401. The impact mechanism 6 includes a third motor 601 fixedly connected to the surface of the lifting platform 402. A rotating rod 602 is rotatably connected to the lower end of the lifting platform 402. The inner circumference of the lifting platform 402 is equal to the outer circumference of the rotating rod 602. The output end of the third motor 601 is fixedly connected to the rotating rod 602. A pull block 603 is fixedly connected to the end of the rotating rod 602. The width of the pull block 603 is smaller than the width of the inner wall of the mounting bracket 503. A pull groove 604 is provided at the upper end of the mounting bracket 503. The pull block 603 is pulled by a pull... The groove 604 is slidably connected to the mounting bracket 503. When the fabric is installed by the positioning mechanism 3, the pull block 603 lifts it to avoid obstructing the installation. After lifting it, the mounting bracket 503 is rotated to release it. The grinding wheel 506 can be dropped freely. The angle of the turntable 302 can be adjusted to simulate the friction state of the fabric under different impact conditions. It is suitable for outdoor sports environments such as sportswear and mountaineering clothing. It can be used to study the abrasion resistance of the fabric when it falls accidentally. It can be used to study the failure mechanism of the fabric under dynamic composite stress and provide experimental basis for the development of impact-resistant and abrasion-resistant fabrics.

[0033] Working principle: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, in use, the garment fabric impact and abrasion performance testing device first places the fabric to be tested on the support platform 309 of the positioning mechanism 3. Pushing the positioning plate 310 causes the extrusion plate 311 to slide down and press the fabric. The positioning bolt 313 slides along the positioning hole 312 to fix the positioning plate 310, ensuring uniform pressing force. Simultaneously, the rubber-wrapped structure of the extrusion plate 311, wider at the top and narrower at the bottom, prevents fabric damage, thus completing fabric positioning. Then, according to the testing requirements, the fabric friction angle is adjusted, and rotating the handle 308 causes the fixing block 307 to rotate, causing the fixing block 307 to lose contact with the slide table 301. After rotating the turntable 302 to the target angle, the handle 308 is rotated again, causing the fixing block 307 to reconnect with the slide 301. At this time, the positioning tooth block 304 engages with the turntable 302, thus fixing the angle. During this process, the matching cooperation between the slide 301 and the turntable 302 ensures the smooth rotation of the turntable 302, and the matching between the first guide rod 303 and the turntable 302 ensures the precise sliding of the positioning tooth block 304. Then, according to the testing requirements, the number of weight blocks 504 are selected and installed on the mounting bracket 503. The fixing sleeve 508 is inserted into the corresponding positioning groove 507, and the inclined block 510 is compressed. The material enters the fixed sleeve 508 and, after being released from compression, opens under the action of the second spring 511 to position the weight 504. The second guide rod 512 ensures that the push plate 509 slides smoothly, preventing the weight 504 from wobbling up and down. Then, the first motor 314 is started, and its output end drives the reciprocating screw 315 to rotate. Since the reciprocating screw 315 is adapted to the slide table 301, and the slide table 301 slides along the limit rod 316 and the bottom support wheel 317 is in contact with the base 1 to reduce friction, the slide table 301 and the fabric positioned above it slide smoothly back and forth along the slide groove 2, realizing the relative positioning of the fabric and the mold 506. Motion basis; Simultaneously, the second motor 404 of the lifting mechanism 4 is started, and its output end drives the lifting rod 405 to rotate. Since the lifting rod 405 is adapted to the lifting platform 402, it drives the lifting platform 402 to slide along the lifting bracket 401 to the target height. The curtain 403 protects the internal structure of the lifting mechanism 4 to prevent debris from affecting the transmission stability. If simple friction detection is to be performed, the abrasive 506 can be directly used to contact the fabric and achieve friction detection with the reciprocating motion of the slide 301. The gravity of the weight 504 is transmitted to the abrasive 506 through the bearing platform 501 to simulate friction scenarios under different pressures.If a combined impact and friction test is performed, the third motor 601 of the impact mechanism 6 is activated. Its output end drives the rotating rod 602 to rotate, causing the pull block 603 to slide along the groove 604 of the mounting bracket 503 and lift the mounting bracket 503. After the lifting platform 402 is adjusted to the target height, the third motor 601 is controlled to reverse and drive the rotating rod 602 to rotate, causing the pull block 603 to disengage from the groove 604 and release the mounting bracket 503. The bearing platform 501 falls freely along the slide rod 502, causing the abrasive 506 to impact the fabric. At the same time, the preset angle of the turntable 302 and the direction of the slide 301 are coordinated. The device undergoes repeated motion to achieve composite impact and friction testing at different angles. During this process, the adaptation between the lifting platform 402 and the rotating rod 602 ensures smooth rotation of the rod 602, and the width adaptation between the pull block 603 and the mounting bracket 503 ensures smooth lifting and releasing actions. During testing, different materials and roughness of the abrasive molds 506 can be replaced as needed, or the number of weights 504 can be adjusted and repositioned using the fixing sleeve 508, adapting to the testing requirements of different wear scenarios. Ultimately, by acquiring wear data of the fabric under different working conditions, the impact and wear performance of the garment fabric is tested.
