Description

Technical Field

[0001] This utility model relates to the field of fabric performance testing technology, and in particular to a device for testing the performance of tear-resistant and abrasion-resistant knitted fabrics. Background Technology

[0002] The performance testing of tear-resistant and abrasion-resistant knitted fabrics mainly focuses on their core durability. Key indicators such as tear strength, abrasion resistance, tensile strength, and color fastness are quantitatively evaluated using specialized equipment. Tear strength is tested using the pendulum method or trapezoidal method to assess the fabric's ability to resist tear propagation. Abrasion resistance is simulated using a Martindale abrasion tester to record the number of revolutions required to reach breakage. Tensile strength is measured using an electronic universal testing machine to measure breaking strength and elongation. Color fastness is tested to ensure color stability under conditions such as washing and friction, ensuring no fading during use. Test results must comply with international (e.g., ISO) or domestic (e.g., GB / T) standards, such as tear strength ≥15N, abrasion resistance ≥10,000 revolutions, and color fastness ≥4, to comprehensively determine whether the fabric meets the durability requirements for outdoor equipment, industrial protection, or high-intensity sportswear.

[0003] Chinese utility model patent CN202410158736.5 discloses a performance testing device for nylon knitted fabrics, belonging to the field of fabric performance testing technology. It includes a test platform with two clamping and fixing ends, and a translational seat with a friction end. The clamping and fixing ends include a control locking component and a winding roller with preliminary clamping elements. Several pressing and fixing elements are arranged circumferentially on the winding roller. This nylon knitted fabric performance testing device not only has high fixation firmness and reliability, continuously and fully meeting testing needs, but also features a simple and efficient process. On the one hand, it effectively improves the stability of the testing process; on the other hand, it facilitates improved testing efficiency and reliability. Furthermore, it can simultaneously or separately perform elasticity and abrasion resistance tests according to testing needs, and can flexibly adjust the testing variables during the testing process to fully simulate the actual use state of the fabric, improving the reliability of the test results and the overall testing efficiency.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the friction components will wear down over time, resulting in a decrease in detection effectiveness; the friction components are inconvenient to replace; their functions are relatively limited; and their tear resistance detection performance is poor. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a device for testing the performance of tear-resistant and abrasion-resistant knitted fabrics.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a tear-resistant and abrasion-resistant knitted fabric performance testing device, comprising: The mounting frame is the foundation for the device, used for positioning and controlling the operation of the device; A friction positioning component is set at the upper end of the detection mounting frame, and a rough abrasive plate with different outer surface roughness is installed inside it; Positioning and fixing frames are installed on both sides of the detection mounting frame to move and detect the fabric. The height adjustment connecting frame is located on the upper side of the positioning and fixing frame and is used to adjust the detection height of the fabric. The fabric clamping structure is fixedly installed at the upper end of the height adjustment connecting frame and is used to clamp and fix the fabric. A dual-axis adjustable pitch screw motor is located at the lower center of the detection mounting frame and is used to adjust the distance between the positioning and fixing frames. A moving drive component, mounted on the upper side of the dual-axis adjustable pitch screw motor, is used to drive the positioning and fixing frame to move. The intelligent touch control center is installed at one end of the detection mounting frame and is used to control the operation of the device.

[0007] By adopting the above technical solutions, this device can accurately test the tear resistance and abrasion resistance of knitted fabrics. The testing mounting frame serves as a stable support for the entire device, ensuring a smooth testing process. The rough abrasive plate on the friction positioning component simulates friction under different usage environments, comprehensively evaluating the abrasion resistance of the fabric. The positioning and fixing frame, in conjunction with the height-adjustable connecting frame, allows for flexible adjustment of the fabric's position and height to adapt to the testing needs of fabrics of different sizes and shapes. The fabric clamping structure ensures the fabric is firmly fixed during the testing process, avoiding testing errors caused by loosening. The synergistic effect of the dual-axis adjustable-pitch screw motor and the moving drive component makes the distance and moving speed between the positioning and fixing frames adjustable, further improving the flexibility and accuracy of the testing. The addition of the intelligent touch control center makes the device easier and faster to operate, improving testing efficiency.

[0008] Furthermore, a limiting mounting groove is formed on the upper surface of the detection mounting frame, and the friction positioning component is installed in the limiting mounting groove.

[0009] By adopting the above technical solution, the limiting mounting groove provides a stable and precise installation position for the friction positioning component, ensuring the stability of the friction positioning component during operation and reducing the risk of displacement caused by vibration or external force.

[0010] Furthermore, the friction positioning element includes: The clamping dual-axis motor is fixedly installed at the center of the limiting mounting groove and is the main control component of the friction positioning component; A mirror-mounted clamping screw is located at the output end of the clamping dual-axis motor for transmitting power; The clamping and fixing plate is slidably installed at both ends of the limiting installation groove, and the lower side is provided with mirror threaded holes that are threadedly connected to the mirror clamping screws respectively.

[0011] By adopting the above technical solution, the dual-axis clamping motor can precisely control the rotation of the mirror clamping screw, thereby driving the clamping fixing plate to slide stably and accurately at both ends of the limiting mounting groove. This design allows the clamping fixing plate to be flexibly adjusted according to the friction requirements of different sizes, ensuring that the friction positioning component can tightly and firmly clamp test materials of various specifications.

[0012] Furthermore, the lower two ends of the detection mounting frame are provided with limiting mounting holes, and the inner sides of both ends of the positioning and fixing frame are provided with supporting limiting rods that are slidably connected to the limiting mounting holes.

[0013] By adopting the above technical solution, the support limiting rod can be inserted into the limiting mounting hole and achieve a sliding connection. This design provides reliable support and limiting for the testing mounting frame. During the testing process, the testing mounting frame may be subjected to various external forces. The cooperation between the support limiting rod and the limiting mounting hole can effectively prevent the testing mounting frame from shaking or shifting excessively, ensuring the stability of the testing mounting frame in the horizontal direction. This, in turn, ensures the accuracy and reliability of the entire performance testing device when conducting tear resistance and abrasion resistance tests, making the test results more accurately reflect the performance of tear-resistant and abrasion-resistant knitted fabrics.

[0014] Furthermore, a mirror-shaped adjusting rod that is threadedly connected to the dual-axis adjusting screw motor is fixedly welded to one side of the center of the positioning and fixing frame, and vertical limiting grooves are provided on both sides of the positioning and fixing frame.

[0015] By adopting the above technical solution, the mirror-image adjusting rod can be precisely threadedly connected to the dual-axis adjusting screw motor. The rotation of the dual-axis adjusting screw motor drives the mirror-image adjusting rod to move stably and accurately. This design allows the positioning and fixing frame to be flexibly adjusted according to different testing requirements, thus adapting to tear-resistant and abrasion-resistant knitted fabrics of different sizes and shapes. Simultaneously, the vertical limiting grooves on both sides of the positioning and fixing frame provide stable limiting and guiding functions for other components during the testing process, ensuring the smoothness and accuracy of the entire testing process.

[0016] Furthermore, the two ends of the height adjustment connecting frame are slidably disposed in the vertical limiting groove, and a height adjustment threaded tube is vertically disposed at its center position. A vertical screw linear motor that is threadedly connected to the height adjustment threaded tube is embedded and installed at the center position of the positioning and fixing frame, and a fixing clamping hole is provided at the upper end of the height adjustment connecting frame.

[0017] By adopting the above technical solution, the two ends of the height adjustment connecting frame slide within the vertical limiting groove, ensuring the stability of its vertical movement and avoiding deviation. The vertically designed height adjustment threaded tube at the center is threadedly connected to the vertical screw linear motor embedded in the center of the positioning and fixing frame. The rotation of the vertical screw linear motor can drive the height adjustment connecting frame to make precise vertical height adjustments, thereby meeting the testing requirements of tear-resistant and abrasion-resistant knitted fabrics of different thicknesses. The fixing clamping hole opened at the upper end of the height adjustment connecting frame can be used to fix and clamp the components or tools required for testing, providing a convenient and stable fixing foundation for the testing operation of the entire performance testing device, further ensuring the smooth progress of the testing process and the accuracy of the test results.

[0018] Furthermore, the fabric clamping member includes: Fixed screws are rotatably installed at both ends of the height adjustment connecting frame; A fixed clamping plate is slidably installed inside the fixed clamping hole, and both ends of the plate are threadedly connected to the fixed screw.

[0019] By adopting the above technical solution, the fixing screws are rotatably installed at both ends of the height adjustment connecting frame, enabling flexible position adjustment and fixing operations. This facilitates adaptation to different specifications of tear-resistant and abrasion-resistant knitted fabrics. The fixing clamping plate is slidably installed inside the fixing clamping hole, with both ends threadedly connected to the fixing screws. The rotation of the fixing screws drives the fixing clamping plate to move smoothly within the fixing clamping hole, thereby accurately clamping the tear-resistant and abrasion-resistant knitted fabric. This ensures that the fabric remains stable during performance testing, preventing slippage or displacement, and provides a reliable guarantee for accurately testing the tear resistance and abrasion resistance of the fabric.

[0020] Furthermore, the moving drive includes: A translation rack is fixedly welded to the upper side of the dual-axis adjustable pitch screw motor and is used to drive the positioning and fixing frame to move back and forth. A translation motor is fixedly installed on the lower inner surface of the positioning frame, and its output end is provided with a power gear that meshes with the translation rack.

[0021] By adopting the above technical solution, the translation rack is fixedly welded to the upper side of the dual-axis adjustable pitch screw motor, providing a stable power transmission track for the back-and-forth movement of the positioning frame, ensuring that the positioning frame can move accurately along the predetermined path; the translation motor is fixedly installed on the lower inner surface of the positioning frame, and its output end is designed with a power gear that meshes with the translation rack, which can convert the rotational power of the translation motor into the linear motion power of the positioning frame. Through the meshing transmission between the power gear and the translation rack, the positioning frame is driven to move back and forth smoothly and accurately, thereby meeting the performance testing requirements of tear-resistant and abrasion-resistant knitted fabrics in different positions, and improving the flexibility and applicability of the testing device.

[0022] In summary, this utility model has the following beneficial effects: 1. In this application, a friction positioning component is used, which facilitates the quick replacement of the rough abrasive plate in the device, thereby improving the convenience and effectiveness of friction detection; 2. In this application, the width inside the device can be flexibly adjusted by using a dual-axis adjustable screw motor and a positioning and fixing frame, thereby achieving the test of the tear resistance effect of the fabric and improving the functionality and practicality of the device.

[0029] The height adjustment connecting frame 5 is set on the upper side of the positioning and fixing frame 4 and is used to adjust the detection height of the fabric. The two ends of the height adjustment connecting frame 5 are slidably set in the vertical limiting groove, and the center position of the height adjustment threaded tube 501 is vertically set. The center position of the positioning and fixing frame 4 is inlaid with a vertical screw linear motor 502 that is threadedly connected to the height adjustment threaded tube 501, and a fixing clamping hole is opened at the upper end of the height adjustment connecting frame 5.

[0030] The fabric clamping structure 6 is fixedly installed at the upper end of the height adjustment connecting frame 5 for clamping and fixing the fabric; the fabric clamping component includes: The fixing screws 601 are rotatably installed at both ends of the height adjustment connecting frame 5; the fixing clamping plate 602 is slidably installed inside the fixing clamping hole, and both ends of it are threadedly connected to the fixing screws 601.

[0031] A dual-axis adjustable pitch screw motor 7 is located at the lower center of the detection mounting frame 1 and is used to adjust the distance between the positioning and fixing frames 4.

[0033] The working principle of the tear-resistant and abrasion-resistant knitted fabric performance testing device in this embodiment is as follows: In use, the tear-resistant and abrasion-resistant knitted fabric to be tested is first placed in the fabric clamping structure 6.
