Description

Technical Field

[0001] This invention relates to the field of textile needle testing technology, specifically to a textile needle abrasion resistance testing device and method. Background Technology

[0002] According to a Chinese patent application with publication number 201910993757.8, a needle abrasion resistance testing device is disclosed. This device simulates the wear and damage caused by needles during use, enabling quick and accurate acquisition of various abrasion resistance data. However, in the prior art, if sand is used instead of textile yarn as the friction medium in textile needle abrasion resistance testing, the fundamental differences in their friction characteristics and contact states will prevent the test results from accurately reflecting the actual service wear of the textile needle. Specifically, sand is a rigid granular material, and its contact with the textile needle is a point-to-surface contact hard abrasive wear, which easily forms scratches, pits, and other destructive damage on the needle surface during the wear process. In actual textile working conditions, the contact between the textile needle and the flexible fiber yarn is a surface-to-surface contact adhesive wear and fatigue wear, with the wear form mainly being progressive wear caused by needle tip blunting and fiber adhesion to the needle shaft surface. Furthermore, the particle size and bulk density of sand are discrete, making it difficult to simulate the stable relative motion trajectory between the yarn and the needle under twisting and stretching conditions, and thus unable to reproduce the dynamic frictional force characteristics between the yarn and the needle in actual production. Therefore, using sand as a testing medium will cause the wear mechanism and wear rate to be severely out of sync with actual working conditions, making it difficult to accurately assess the true abrasion resistance of the textile needle. To address these issues, we propose a textile needle abrasion resistance testing device and method. Summary of the Invention

[0003] The present invention provides the following technical solution: a textile needle abrasion resistance testing device, comprising a base and a testing device combined with the top of the base, characterized in that: the testing device is fixedly installed on the top of the base along the length direction of the base, for testing the abrasion resistance of textile needles, and the number of testing devices is at least one set;

[0004] The testing equipment includes:

[0005] A fixed platform, which is bolted to the top of the base;

[0006] Guide component one is fixedly installed on the top of the fixed platform, and a lifting platform is vertically and slidably installed on the top of the fixed platform through guide component one;

[0015] As a preferred embodiment of the present invention, two guide members are fixedly installed on the top of the fixed platform, and a crossbeam is vertically slidably installed on the top of the fixed platform through the two guide members. A mounting sheet metal is fixedly installed on the side of the crossbeam near the station plate. Three stake blocks are installed at equal intervals along the length of the mounting sheet metal at the front end of the mounting sheet metal. Quick clamps are fixedly installed on the side of the three stake blocks away from the mounting sheet metal. The quick clamps and stake blocks form a clamping and fixing mechanism for the textile needle being tested. Initially, the textile needle clamped by the quick clamps and stake blocks is located on the top of the test strip near the station plate.

[0016] As a preferred embodiment of the present invention, a gantry frame is fixedly installed on the top of the fixed platform, a servo electric cylinder is fixedly installed on the top of the gantry frame, and a spring is fixedly installed between the bottom of the piston rod of the servo electric cylinder and the top of the crossbeam.

[0017] As a preferred embodiment of the present invention, the guide component two includes a guide shaft support two fixedly installed on the top of the fixed platform, a guide shaft two fixedly installed on the top of the guide shaft support two, a linear bearing two slidably installed on the periphery of the guide shaft two, the linear bearing two being fixedly installed to the crossbeam by bolts, a shaft fixing ring fixedly installed on the outer wall of the guide shaft two, and a spring two sleeved on the periphery of the guide shaft two, the spring two being fixedly installed between the top of the shaft fixing ring and the bottom of the linear bearing two, wherein the elastic force of the spring three is greater than the total elastic force of the two spring two.

[0018] As a preferred embodiment of the present invention, a stop post is fixedly installed at the bottom of the piston rod of the servo electric cylinder. The stop post is located inside the spring. A through hole is provided at the top of the crossbeam to accommodate the passage of the stop post. A stop frame is fixedly installed at the top of the lifting platform. The stop frame is located at the bottom of the through hole. Initially, the top of the stop frame does not contact the bottom of the stop post.

[0019] As a preferred embodiment of the present invention, the sliding member includes a slider fixedly installed at the bottom of the transverse moving plate and a straight rail fixedly installed at the top of the lifting platform, wherein the slider is slidably installed around the straight rail.

[0020] As a preferred embodiment of the present invention, the guide component includes a guide shaft support fixedly installed on the top of the fixed platform, a guide shaft is fixedly installed on the top of the guide shaft support, a linear bearing is slidably installed on the periphery of the guide shaft, the linear bearing is fixedly installed to the lifting platform by bolts, and a spring is sleeved on the periphery of the guide shaft, the spring being fixedly installed between the top of the guide shaft support and the bottom of the linear bearing.

[0021] As a preferred embodiment of the present invention, a power device is fixedly installed at one end of the station plate. The power device includes a power motor fixedly installed on the station plate, a main synchronous pulley fixedly installed on the output shaft of the power motor, and a driven synchronous pulley fixedly installed on the central shaft of one of the grooved pulleys. A synchronous belt is fixedly installed between the driven synchronous pulley and the main synchronous pulley.

[0022] A test method for a textile needle abrasion resistance testing device includes the following steps:

[0023] S1. The quick clamp and the stake block clamp and fix the textile needle to be tested.

[0024] S2. The piston rod of the servo electric cylinder pushes the crossbeam downward through the spring three. The downward movement of the crossbeam drives the installation sheet metal, pile block, quick clamp and the clamped placement pin to move downward to the test position.

[0025] S3. The servo electric cylinder piston rod pushes the abutment column down to abut the top of the abutment frame, pushing the lifting platform, sliding parts, lateral moving plate, station plate, groove wheel one, groove wheel two, groove wheel three and test strip down. At the same time, the tension spring releases the rebound force to drag the lifting platform to move laterally, and the roller rolls down along the path groove path, and the test strip contacts the inner surface of the textile needle hook.

[0026] S4. The power equipment drives the test bar to rotate around Grooved Wheel 1, Grooved Wheel 2 and Grooved Wheel 3, generating relative motion between the test bar and the hook of the textile needle, and performs abrasion resistance testing on the textile needle.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. This invention uses a power motor to provide rotational torque to drive the main synchronous pulley to rotate. Under the transmission of the synchronous belt, the driven synchronous pulley and the first grooved pulley connected to the driven synchronous pulley rotate. Ultimately, the test strip rotates around the periphery of the first, second, and third grooved pulleys, causing the surface of the test strip to come into contact with the inner wall of the needle hook of the textile needle and generate relative movement between the test strip and the rotating test strip. This solves the problem that the traditional method of using sand as a test medium is difficult to accurately assess the true wear resistance of textile needles.

[0029] 2. In the initial stage of this invention, since the textile needle held by the quick clamp and the pile block is located on the top of the test strip near the station plate, the textile needle will not come into contact with the test strip during its downward movement. Instead, it will move along the side of the test strip until the hook of the textile needle moves to the lower side of the test strip. This setting ensures that the textile needle will not squeeze the test strip during its downward movement, thus preventing deformation and damage to the test strip. At the same time, the textile needle will not be deformed or damaged by the reverse force of the test strip.

[0030] 3. In this invention, after the test needle is pushed downward to the test position by a servo cylinder piston rod, the servo cylinder piston rod continues to push downward due to the flexible connection of spring three. Then, the servo cylinder piston rod pushes the bottom of the abutment column through the through hole to contact the top of the abutment frame, pushing the abutment frame downward. With the help of the elastic force of the tension spring, the roller rolls along the path groove. Finally, the station plate drives the power equipment, grooved roller one, grooved roller two, grooved roller three and the test strip to move laterally together, moving the test strip into the inside of the needle hook of the textile needle. After that, the roller moves vertically downward under the action of the path groove, causing the test strip to stop moving laterally and then turn to move vertically downward. Finally, the surface of the test strip comes into contact with the inner wall of the needle hook of the textile needle.

[0031] 4. In this invention, the piston rod of the servo electric cylinder moves upward, and the spring under compression releases its elastic force, pushing the lifting platform, sliding parts, lateral moving plate, and station plate upward. The roller moves vertically upward along the path groove, causing the test strip to move upward to the top of the needle hook of the textile needle. Then, under the action of the roller and the path groove, the test strip moves laterally while moving upward, moving away from the inside of the needle hook of the textile needle. As the piston rod of the servo electric cylinder continues to move upward back to the initial position, the crossbeam, mounting sheet metal, stake block, quick clamp, and the tested textile needle are finally lifted upward to the initial position. Since the test strip has been moved away from the side of the textile needle, there will be no contact interference between the textile needle and the test strip during the upward reset process, so that the textile needle can be removed after the test.

[0049] 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.

[0050] Please see Figures 1 to 16 The technical solution provided by the present invention specifically includes the following embodiments:

[0051] A textile needle abrasion resistance testing device includes a base 100 and a testing device 200 connected to the top of the base 100. The testing device 200 is fixedly installed on the top of the base 100 along the length direction of the base 100 and is used for textile needle abrasion resistance testing. The specific number of testing devices 200 is not fixed, but at least one set is included.

[0052] For further details, please refer to [link / reference]. Figure 6 , Figure 7 , Figure 9 As shown:

[0053] The testing equipment 200 includes a fixed platform 201, a guide component 1 202, a lifting platform 203, a sliding component 204, a transverse moving plate 205, a platform 206, a grooved wheel 1 207, a grooved wheel 208, a grooved wheel 3 209, and a test strip 2010. The fixed platform 201 is bolted to the top of the base 100. The guide component 1 202 is fixedly installed on the top of the fixed platform 201. The lifting platform 203 is vertically slidably installed on the top of the fixed platform 201 via the guide component 1 202. The transverse moving plate 205 is slidably installed on the lifting platform 203 via the sliding component 204. At the top, the sliding member 204 provides guidance for the lateral moving plate 205 to slide along the top of the lifting platform 203, thereby ensuring the stability of the lateral moving plate 205. A wheel groove 2005 is formed through the top of the lateral moving plate 205. The station plate 206 is fixedly installed at the front end of the top of the lateral moving plate 205. Grooved wheel one 207 is rotatably installed at both ends of the front part of the station plate 206. Grooved wheels two 208 and three 209 are rotatably installed at the front of the lateral moving plate 205. The test strip 2010 is wrapped around the outside of grooved wheels one 207, two 208, and three 209. The test strip 2010 is arranged to rotate around the periphery of Geneva 1 207, Geneva 208, and Geneva 3 209. The material of the test strip 2010 includes carbon fiber filaments, metal wires, etc., and the specific material used is selected according to the actual testing requirements, but is not limited to carbon fiber filaments, metal wires, etc. A power device 2011 is fixedly installed at one end of the station plate 206. The power device 2011 includes a power motor 20111 fixedly installed on the station plate 206, a main synchronous pulley 20112 fixedly installed on the output shaft of the power motor 20111, and a fixed... The slave synchronous pulley 20113 is mounted on the central shaft of one of the grooved pulleys 207. A synchronous belt 20114 is fixedly installed between the slave synchronous pulley 20113 and the main synchronous pulley 20112. The main synchronous pulley 20112 is driven to rotate by the rotational torque provided by the power motor 20111. Under the transmission of the synchronous belt 20114, the slave synchronous pulley 20113 and the grooved pulley 207 connected to the slave synchronous pulley 20113 are driven to rotate, so that the test bar 2010 rotates around the periphery of the grooved pulley 207, the second grooved pulley 208 and the third grooved pulley 209.

[0054] For further details, please refer to [link / reference]. Figure 3 , Figure 5 , Figure 8 , Figure 11 , Figure 13 As shown:

[0055] A gantry frame 2024 is fixedly installed on the top of the fixed platform 201. A servo cylinder 2025 is fixedly installed on the top of the gantry frame 2024. Two guide members 2019, distributed left and right, are fixedly installed on the top of the fixed platform 201. A crossbeam 2020 is vertically slidably installed on the top of the fixed platform 201 via the two guide members 2019. A spring 3 2027 is fixedly installed between the bottom of the piston rod of the servo cylinder 2025 and the top of the crossbeam 2020. The piston rod of the servo cylinder 2025 drives the spring 3 2027 to move downward, and under the elastic force of the spring 3 2027, the crossbeam 2020 moves downward along the guide trajectory of the guide members 2019. A mounting sheet metal 2021 is fixedly installed on the side of the crossbeam 2020 closest to the station plate 206. Three pile blocks 2022 are installed at equal intervals along the length of the mounting sheet metal 2021 at the front end of the mounting sheet metal 2021. The three pile blocks 2022 are located away from the mounting sheet metal 2021. Quick clamps 2023 are fixedly installed on both sides. The quick clamps 2023 and the stake block 2022 form a clamping and fixing mechanism for the textile needle being tested. This allows the textile needle to move downwards along with the sheet metal 2021, stake block 2022, and quick clamps 2023 during the downward movement of the crossbeam 2020. Initially, the textile needle held by the quick clamps 2023 and stake block 2022 is located on the top of the test strip 2010 near the station plate 206. Therefore, the textile needle will not come into contact with the test strip 2010 during its downward movement. Instead, it will move along the side of the test strip 2010 until the hook of the textile needle moves to the lower side of the test strip 2010. This design prevents the textile needle from squeezing the test strip 2010 during its downward movement, thus preventing deformation and damage to the test strip 2010. At the same time, the textile needle will not be deformed or damaged by the reverse force of the test strip 2010.

[0056] It should be further noted that guide component 2019 includes guide shaft support 201901 fixedly installed on the top of fixed platform 201. Guide shaft 201902 is fixedly installed on the top of guide shaft support 201901. The connection between guide shaft 201902 and fixed platform 201 is more stable through guide shaft support 201901. Linear bearing 201903 is slidably installed on the periphery of guide shaft 201902. Linear bearing 201903 is connected to the guide shaft 201902 by bolts. The crossbeam 2020 is fixedly installed so that it can move precisely along the periphery of the guide shaft 201902 via the connection of the linear bearing 201903. A shaft retaining ring 201904 is fixedly installed on the outer wall of the guide shaft 201902. A spring 201905 is sleeved around the guide shaft 201902, and is fixedly installed between the top of the shaft retaining ring 201904 and the bottom of the linear bearing 201903. The spring 201905 is designed to... The springs provide upward elastic support to the crossbeam 2020, ensuring that when the piston rod of the servo cylinder 2025 is not performing downward work, the elastic force of spring 201905 provides upward support to the crossbeam 2020, mounting sheet metal 2021, stake block 2022, and quick clamp 2023, preventing them from moving downward and maintaining them at the detection height. The elastic force of spring 2027 is greater than the combined elastic force of the two springs 201905, causing the piston rod of the servo cylinder 2025 to push the spring downward. During the process of spring 2027, the two springs 201905 are compressed first. When the compression stroke of the two springs 201905 is at its maximum, that is, when the crossbeam 2020 reaches the lower stop point, i.e. when the textile needle reaches the test position, if the piston rod of the servo cylinder 2025 continues to push the spring 2027 downward, the bottom of the spring 2027 will stop moving downward with the crossbeam 2020, while the top of the spring 2027 will be compressed and store elastic force by the piston rod of the servo cylinder 2025 which continues to move downward.

[0057] For further details, please refer to [link / reference]. Figure 7 , Figure 9 , Figure 11 As shown:

[0058] The sliding component 204 includes a slider 20401 fixedly installed at the bottom of the transverse moving plate 205 and a straight rail 20402 fixedly installed at the top of the lifting platform 203. The slider 20401 is slidably installed around the straight rail 20402. Through the sliding connection between the slider 20401 and the straight rail 20402, the transverse moving plate 205 is guided to slide along the top of the lifting platform 203, ensuring the accuracy of the sliding trajectory of the transverse moving plate 205. The guide component 202 includes a guide shaft support 20201 fixedly installed at the top of the fixed platform 201. A guide shaft 20202 is fixedly installed on the top of the guide shaft support 20201. A linear bearing 20203 is slidably installed around the guide shaft 20202. 03. The guide shaft 20202 is fixedly installed to the lifting platform 203 by bolts. A spring 20204 is sleeved around the guide shaft 20202. The spring 20204 is fixedly installed between the top of the guide shaft support 20201 and the bottom of the linear bearing 20203. The connection between the guide shaft 20202 and the guide component 202 through the guide shaft support 20201 can be more stable, so that the sliding connection between the lifting platform 203 and the guide shaft 20202 through the linear bearing 20203 is more stable, and the vertical movement accuracy of the lifting platform 203 is higher. At the same time, the elasticity of the spring 20204 provides upward support for the lifting platform 203. In the initial state, the lifting platform 203 will not move under the sliding connection between the linear bearing 20203 and the guide shaft 20202. As the servo cylinder 2025 piston rod moves downward, a stop post 2026 is fixedly installed at the bottom. The stop post 2026 is located inside the spring 2027. A through hole 2012 is provided at the top of the crossbeam 2020 to accommodate the stop post 2026. The through hole 2012 ensures that the stop post 2026 moves unimpeded as the piston rod of the servo cylinder 2025 pushes it downward. A support frame 2028 is fixedly installed at the top of the lifting platform 203. The support frame 2028 is located at the bottom of the through hole 2012. Initially, the top of the support frame 2028 does not contact the bottom of the stop post 2026. When the piston rod of the servo cylinder 2025 performs work and the crossbeam 2020 reaches its lower limit, the piston rod of the servo cylinder 2025 continues to push the spring 2027 downward. Spring 2027 is compressed to store elastic force, while the bottom of the abutment 2026 passes through the through hole 2012 and contacts the top of the abutment 2028, pushing the abutment 2028 downward. A roller 2013 is rotatably installed inside the wheel groove 2005. A guide block 2014 is fixedly installed on the top of the lifting platform 203. A path groove 2015 is opened on the side of the guide block 2014 near the roller 2013. The outer wall of the roller 2013 contacts the inner wall of the path groove 2015. A screw 1 2016 is fixedly installed at the bottom of the transverse moving plate 205. A screw 2 2017 is fixedly installed on the top of the lifting platform 203. Screw 2 2017 is located on the side of screw 1 2016 away from the platform 206. A tension spring 2018 is fixedly installed between screw 1 2016 and screw 2 2017. Initially…When the tension spring 2018 is in a stretched state, it is pushed downward by the abutment 2028, which causes the lifting platform 203, sliding member 204, lateral moving plate 205, station plate 206, and roller 2013 to move downward along the guide trajectory of the guide member 202. The spring 20204 is compressed and stores elastic force. During this process, the roller 2013 is caused to roll along the path of the path groove 2015 due to the rebound force of the tension spring 2018. In other words, as the lateral moving plate 205 and station plate 206 move downward, the elastic force of the tension spring 2018 causes them to roll along the path of the path groove 2015. Simultaneously, it exhibits a lateral movement characteristic along the sliding guide trajectory of the slider 204. Ultimately, through the station plate 206, it drives the power device 2011, grooved wheel one 207, grooved wheel two 208, grooved wheel three 209, and test strip 2010 to move laterally together, moving the test strip 2010 into the inside of the needle hook of the textile needle. Then, the roller 2013 moves vertically downward under the action of the path groove 2015, causing the test strip 2010 to terminate its lateral movement and then switch to vertical downward movement. Finally, the surface of the test strip 2010 comes into contact with the inner wall of the needle hook of the textile needle (as per the attached instruction manual). Figure 16 As shown), relative movement occurs between the test strip 2010 and the rotating test strip, thereby testing the abrasion resistance of the textile needle.

[0059] After the test, the piston rod of the servo cylinder 2025 moves upward. Conversely, the spring 20204, which was under compression, releases its rebound force, pushing the lifting platform 203, sliding member 204, transverse moving plate 205, and station plate 206 upward. The roller 2013 moves vertically upward along the path groove 2015, causing the test strip 2010 to move upward to the top of the needle hook of the textile needle. Then, under the action of the roller 2013 and the path groove 2015, the test strip 2010 also... Simultaneously, it moves laterally, moving away from the inside of the needle hook of the textile needle. As the piston rod of the servo electric cylinder 2025 continues to move upward back to the initial position, the crossbeam 2020, mounting sheet metal 2021, stake block 2022, quick clamp 2023, and the tested textile needle are finally lifted upward to the initial position. Since the test strip 2010 has been moved away from the side of the textile needle, there will be no contact interference between the textile needle and the test strip 2010 during the upward reset process, so that the textile needle can be removed after the test.

[0060] A test method for a textile needle abrasion resistance testing device includes the following steps:

[0061] S1. Quick clamp 2023 and stake block 2022 clamp and fix the textile needle to be tested;
