Description

Technical Field

[0001] This utility model relates to the field of textile testing technology, specifically a fixture for testing the abrasion resistance of textiles. Background Technology

[0002] During the production and use of textiles, abrasion resistance is one of the important indicators for measuring their quality and service life. In order to ensure that textiles meet the needs of different application scenarios, it is necessary to accurately test their abrasion resistance. At present, the textile abrasion resistance testing equipment commonly used on the market has many shortcomings when clamping and tensioning textiles.

[0003] Some testing equipment's clamping components cannot stably hold textiles, which can easily lead to textile displacement during testing, resulting in inaccurate test results. At the same time, existing tension adjustment mechanisms are complex to operate, making it difficult to quickly and accurately adjust the tension according to textiles of different thicknesses and materials, thus affecting testing efficiency.

[0004] To address these issues, this invention provides a fixture for testing the abrasion resistance of textiles. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a textile abrasion resistance testing fixture, which solves the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a textile abrasion resistance testing fixture, comprising a base plate, a clamping assembly on the top of the base plate, a tension adjustment assembly between the clamping assemblies, and a detection assembly above the base plate. The clamping assembly includes two movable blocks, both slidably connected to the top of the base plate. A first bracket is fixedly mounted on the top of each movable block, and a first screw is threaded through the top of the first bracket. A clamping plate is rotatably connected to the bottom of the first screw, and the clamping plate is positioned above the corresponding movable block. A first knob is fixedly mounted on the top of the first screw. By rotating the first knob, the first screw rotates, thereby pushing the clamping plate up and down, achieving clamping and releasing of the textile, making the operation simple and convenient.

[0007] Preferably, a first limiting rod is fixedly installed on the top of the clamping plate, and the first limiting rod movably passes through the top of the corresponding moving block. The first limiting rod can limit the movement direction of the clamping plate, prevent the clamping plate from shifting during up and down movement, and ensure the stability of clamping. Preferably, the thread lead angle of the first screw is smaller than the equivalent friction angle, giving the first screw a self-locking function. This prevents the first screw from rotating on its own due to external forces after clamping the textile, thus affecting the clamping effect. The outer side of the first screw is coated with a lubricating grease that has strong adhesion, is anti-leakage, wear-resistant, and anti-pollution properties. This reduces friction between the first screw and the first support, extends its service life, and ensures smooth rotation of the first screw. The two moving blocks are symmetrical about the center of the base plate, ensuring uniform force on the textile during clamping and tensioning. Preferably, the tension adjustment assembly includes two side plates, which are fixedly installed on the left and right sides of the top of the base plate, respectively. A second screw is rotatably connected between the two side plates. The threads on both sides of the center of the second screw have different directions of rotation, and two moving blocks are screwed onto the outer sides of the threads with different directions of rotation on the second screw. When the second screw is rotated, because the threads on both sides rotate in opposite directions, the two moving blocks will move in opposite directions or in opposite directions along the second screw, thereby adjusting the tension of the textile. Preferably, a second limiting rod is fixedly installed between the two side plates. This second limiting rod movably penetrates the interior of both moving blocks, restricting the direction of movement of the moving blocks and preventing them from deflecting as the second screw rotates, thus ensuring the stability and accuracy of the moving blocks' movement. A rotating rod is rotatably connected to the right side of each side plate. A second knob is fixedly installed at the outer end of the rotating rod, and the inner end of the rotating rod movably penetrates the interior of the side plate and is fixedly connected to the second screw. Rotating the second knob causes the rotating rod and the second screw to rotate synchronously, facilitating tension adjustment by the operator. Preferably, the thread lead angle of the second screw is less than the equivalent friction angle, giving the second screw a self-locking capability. After the tension of the textile is adjusted, the second screw can be prevented from rotating on its own, ensuring a stable tension. The outer side of the second screw is coated with a lubricating grease that has strong adhesion, is anti-leakage, wear-resistant, and anti-pollution, reducing frictional loss between the second screw and the moving block, improving the service life of the equipment, and ensuring the smooth movement of the moving block. Preferably, the detection assembly includes a second bracket, which is fixedly mounted on the top of a base plate. A top plate is fixedly mounted on the top of the second bracket, and an electric slide rail is fixedly mounted on the bottom of the top plate. A track slider is slidably connected to the outer bottom of the electric slide rail, and a hydraulic rod is fixedly mounted on the bottom of the track slider. A friction plate is fixedly mounted on the output end of the hydraulic rod. The electric slide rail can drive the track slider, hydraulic rod, and friction plate to move horizontally. The hydraulic rod can adjust the pressure between the friction plate and the textile. Through the reciprocating friction of the friction plate on the surface of the textile, the abrasion resistance of the textile is detected. Preferably, a bottom support frame is fixedly installed on the top of the base plate and between the two movable blocks, and the bottom support frame is located directly below the friction plate. The bottom support frame can support the test area of ​​the textile, prevent the textile from sinking due to force during the friction test, ensure uniform contact between the friction plate and the textile, and improve the accuracy of the test results.

[0008] Beneficial effects This invention provides a fixture for testing the abrasion resistance of textiles. Compared with the prior art, it has the following advantages: 1. This textile abrasion resistance testing fixture, by setting up a clamping assembly, uses a first screw to drive the clamping plate to move up and down to clamp the textile. With the limiting effect of the first limiting rod, it can stably fix the textile, prevent the textile from shifting during the test, and ensure the accuracy of the test results. At the same time, the self-locking function of the first screw and the grease coating further improve the stability of the clamping and the service life of the equipment.

[0009] 2. This textile abrasion resistance testing fixture uses a tension adjustment component with a second screw on each side having different thread directions. Rotating the second knob can drive the two moving blocks to move towards or away from each other, achieving rapid adjustment of the textile tension. The operation is convenient and efficient. The setting of the second limit rod ensures the stability of the moving block movement, and the self-locking function of the second screw and the grease coating also ensure the stability of the tension and the durability of the equipment.

[0016] A first limiting rod 26 is fixedly installed on the top of the clamping plate 23, and the first limiting rod 26 movably passes through the top of the corresponding moving block 21.

[0017] The lead angle of the first screw 24 is less than the equivalent friction angle. The outer side of the first screw 24 is coated with a lubricating grease that has strong adhesion, is anti-leakage, wear-resistant and anti-pollution. The two moving blocks 21 are symmetrical about the center of the base plate 1.

[0018] The tension adjustment assembly 3 includes two side plates 31, which are fixedly installed on the left and right sides of the top of the base plate 1 respectively. A second screw 32 is rotatably connected between the two side plates 31. The threads on both sides of the center of the second screw 32 have different directions of rotation.

[0022] In this embodiment: Regular cleaning: After each use of the equipment, dust, fibers, and other debris should be cleaned from the surface of the equipment in a timely manner, especially the moving parts of the clamping assembly 2, tension adjustment assembly 3, and detection assembly 4, such as the contact surface between the moving block 21 and the base plate 1, the mating point between the first screw 24 and the first bracket 22, the mating point between the second screw 32 and the moving block 21, and the contact surface between the electric slide rail 46 and the track slider 47, to prevent debris from affecting the normal operation of the equipment. A soft brush or compressed air can be used for cleaning; avoid using corrosive cleaning agents. Lubrication maintenance: Regularly check the condition of the grease on the outside of the first screw 24 and the second screw 32. When the grease is lost, deteriorated or contaminated, the old grease should be cleaned up in time and a new grease with strong adhesion, anti-loss, wear resistance and anti-contamination should be applied. The amount of grease should be enough to cover the thread surface. Lubrication maintenance should usually be performed once every 50 uses or once a month. Component Inspection: Regularly check the connections of each component, such as whether the connecting bolts between the base plate 1 and the side plate 31, the connecting bolts between the moving block 21 and the first bracket 22, and the connecting bolts between the top plate 43 and the second bracket 42 are loose; whether the bearings at both ends of the first screw 24 and the second screw 32 are worn; and whether the first limit rod 26 and the second limit rod 33 are deformed. If any component is found to be loose, it should be tightened in time. If the bearing is severely worn or the limit rod is deformed, the corresponding component should be replaced in time, such as replacing the worn bearing, the deformed first limit rod 26 or the second limit rod 33, to ensure the normal operation of the equipment and the accuracy of the test.

[0023] Electrical system maintenance: Regularly check the wiring of electrical components such as the electric slide rail 46 and hydraulic rod 44 to ensure it is secure and free from damage or aging.

Check the operation of the electrical control system to ensure that the control buttons and indicator lights are functioning properly. For example, check if the electric slide rail 46 operates normally after the start button is pressed, and if the lifting indicator light of the hydraulic rod 44 accurately displays the status. Electrical system maintenance should be performed by qualified personnel to prevent unauthorized disassembly or repair.

[0024] Furthermore, all contents not described in detail in this specification are existing technologies known to those skilled in the art, and all electrical components mentioned in this document are powered by external power supply lines.

[0025] Working principle: During operation, the textile to be tested is first laid flat on top of the two moving blocks 21, so that the testing area of ​​the textile is directly above the bottom support frame 41. Then, the first knob 25 is turned, which drives the first screw 24 to rotate. The first screw 24 pushes the clamping plate 23 downward. With the limiting action of the first limiting rod 26 on the clamping plate 23, the two ends of the textile are stably clamped between the clamping plate 23 and the moving block 21. The first screw 24 achieves self-locking because its thread lead angle is less than the equivalent friction angle, preventing the clamp from loosening. Next, the second knob 35 is turned, which drives the rotating rod 34 and the second screw 32 to rotate synchronously. Because the threads on both sides of the center of the second screw 32 have different directions of rotation, Two moving blocks 21 move in opposite directions along the second limiting rod 33 to adjust the tension of the textile. After adjustment, the second screw 32 maintains the tension through a self-locking function. Finally, the electric slide rail 46 and hydraulic rod 44 are activated. The hydraulic rod 44 pushes the friction plate 45 downward, so that the friction plate 45 is in close contact with the textile test area and adjusted to the set pressure. The electric slide rail 46 drives the track slider 47, hydraulic rod 44 and friction plate 45 to reciprocate in the horizontal direction. The friction plate 45 rubs against the surface of the textile. At the same time, the bottom support frame 41 supports the textile test area to prevent the textile from sinking, thereby completing the textile abrasion resistance test.
