Description

Technical Field

[0001] The present invention relates to the technical field of wear resistance testing, and more particularly to a textile wear resistance testing device. Background Art

[0002] A textile's wear resistance is a key quality indicator. A wear test device can simulate the friction experienced by textiles during actual use. Through precise testing methods, it can detect whether a garment fabric exhibits fuzzing, pilling, or breakage after a certain number of friction events, thereby determining whether it meets quality requirements. Raw material selection is crucial in textile production. Different fiber materials, yarn structures, and fabric weaves significantly impact wear resistance. A wear test device can help manufacturers select materials with superior wear resistance during raw material procurement. Consumers often desire a long lifespan when purchasing textiles. Textiles with excellent wear resistance can withstand the friction and wear of daily use and are less susceptible to damage, thus meeting consumer demand for product durability.

Detailed implementation manners

[0030] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. In addition, the forms of each structure described in the following implementation manners are merely examples. A textile wear resistance testing device related to the present invention is not limited to the structures described in the following implementation manners. All other implementation manners obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0031] Refer to Figures 1 - 3 and Figure 10, the present invention provides a textile wear resistance testing device, including a housing assembly 1. The housing assembly 1 includes a foundation plate 101. The top of the foundation plate 101 is provided with an upper housing 102. The inner top side of the upper housing 102 is provided with a first T-shaped groove 103. The top of the foundation plate 101 is provided with a pit 104. The inside of the first T-shaped groove 103 is slidably connected with a discharging assembly 2. Above the foundation plate 101 is provided a feeding assembly 3. One side of the feeding assembly 3 is provided with a placing assembly 8. The side of the placing assembly 8 is provided with a first transmission assembly 5. A workpiece to be ground 10 is installed between the placing assembly 8 and the feeding assembly 3. Above the workpiece to be ground 10 is provided a wear testing assembly 4. The top of the foundation plate 101 is provided with a ranging plate 6. The ranging plate 6 is located between the placing assembly 8 and the foundation plate 101. The two sides of the placing assembly 8 are provided with a second transmission assembly 7. The inside of the placing assembly 8 is provided with a punching and tensioning assembly 9;

[0032] The wear testing assembly 4 includes a rotating box 401. The outside of the rotating box 401 is provided with a plurality of placing grooves 402. The inside of the placing grooves 402 is slidably connected with wear testing heads 403. The inside of the wear testing heads 403 is fixedly connected with a force reducing box 404. The inside of the force reducing box 404 is fixedly connected with a first rack 405. The force reducing box 404 is slidably and tightly connected with the wear testing heads 403. One side of the first rack 405 is meshed with a driving gear 406. The center of the driving gear 406 is key-connected with the rotating shaft of a second motor 408. The center of the rotating box 401 is key-connected with a rotating rod 407. The end of the rotating rod 407 is key-connected with a third motor 409;

[0033] In this embodiment, it should be specifically noted that: a suitable grinding head can be sleeved outside the wear testing head 403 to adapt to different materials. Since the force reducing box 404 is slidably and tightly connected with the wear testing head 403, the shear force received by the first rack 405 during the wear resistance test can be reduced, and the service life of the device can be prolonged.

[0034] The main difference between this embodiment and the prior art lies in the initiative of using the second motor 408 and the third motor 409 in this embodiment to change the number of wear testing heads 403 extending out of the rotating box 401, realizing a change in the mechanical structure and thus changing the grinding frequency of the wear testing assembly 4, specifically in the wear testing assembly 4, the placing assembly 8, and the punching and tensioning assembly 9;

[0035] The above structure is the main structure of this embodiment, which solves the problem of automatic wear resistance testing of the wear testing assembly 4. The second motor 408 and the third motor 409 are existing structures, and the specific structures and connection methods of the second motor 408 and the third motor 409 are not specifically described in this embodiment.

[0036] Refer to Figure 1 and Figure 2, the discharging assembly 2 includes a T-shaped block 201 which is slidably connected to the first T-shaped groove 103. A telescopic electric rod 202 is fixedly connected to the bottom of the T-shaped block 201, and an electric mechanical claw 203 is fixedly connected to the bottom of the telescopic electric rod 202.

[0037] In this embodiment, it should be specifically noted that: when the fixation of the workpiece 10 to be ground is released, the electric mechanical claw 203 moves to directly above the workpiece 10 to be ground, the telescopic electric rod 202 gradually extends until the electric mechanical claw 203 contacts the workpiece 10 to be ground. After the electric mechanical claw 203 grabs the workpiece 10 whose fixation has been released, it moves to directly above the pit 104, and the electric mechanical claw 203 releases the workpiece 10 to be ground, and the workpiece 10 to be ground falls into the pit 104. The telescopic electric rod 202 and the electric mechanical claw 203 are existing structures, and the specific structures and connection methods of the telescopic electric rod 202 and the electric mechanical claw 203 will not be specifically described in this embodiment.

[0038] Refer to Figures 1 - 3 , the feeding assembly 3 includes two support columns 301. The bottoms of the support columns 301 are fixedly connected to the top of the base plate 101. A support plate 302 is fixedly connected to the tops of the two support columns 301. Straight groove holes are provided on the side walls of the two support columns 301. A pressure roller 304 is slidably connected to the straight groove holes of the support columns 301. A groove 305 is provided on the upper side of the pressure roller 304. A plurality of first air cylinders 303 are provided between the groove 305 and the support plate 302. A lower roller 307 is provided directly below the pressure roller 304. One end of the lower roller 307 is fixedly connected to the rotating shaft of a first motor 306, and both ends of the lower roller 307 are rotatably connected to the two support columns 301.

[0039] In this embodiment, it should be specifically noted that: the workpiece 10 to be ground is passed through the gap between the pressure roller 304 and the lower roller 307. The first air cylinder 303 is started, and the first air cylinder 303 pushes the pressure roller 304 downward to clamp the workpiece 10 to be ground. The first motor 306 is started, and the first motor 306 drives the lower roller 307 to rotate. The rotation of the lower roller 307 drives the workpiece 10 to move to the right. Finally, the front part of the workpiece 10 to be ground reaches the inside of the placing assembly 8, and the first motor 306 and the lower roller 307 stop rotating. At this time, the first air cylinder 303 drives the pressure roller 304 to continue to press down to tightly press the workpiece 10 to be ground.

[0040] Refer to Figures 1 - 3 and Figure 7, the first transmission component 5 includes a fourth motor 501. A screw rod 504 is fixedly connected to the rotating shaft of the fourth motor 501. A pulley 503 is fixedly connected to the outer side of the screw rod 504. Both ends of the screw rod 504 are rotatably connected to a first bracket 502. One end of a transmission belt 505 is movably connected to the outer side of the pulley 503. The other end of the transmission belt 505 is movably connected to another pulley 503. Another screw rod 504 is fixedly connected to this pulley 503. Both ends of this screw rod 504 are rotatably connected to a first bracket 502. A placing component 8 is in screw transmission connection with the outer side of the screw rod 504. The thread sizes on both sides of the screw rod 504 are the same but the helix directions are opposite.

[0041] In this embodiment, it should be specifically noted that: when the fourth motor 501 is started, the fourth motor 501 drives the screw rod 504 to rotate. The screw rod 504 drives the pulley 503 fixedly connected to the screw rod 504 to rotate. The rotation of the pulley 503 drives the pulley 503 and the screw rod 504 at the other end of the transmission belt 505 to rotate through the transmission belt 505. Since the helix directions of the threads on both sides of the screw rod 504 are different, the placing components 8 at both ends of the screw rod 504 move away from each other.

[0042] Refer to Figure 2 , Figure 3 and Figure 8 , the second transmission component 7 includes a fifth motor 701. The housing of the fifth motor 701 is fixedly connected to the bottom of the base plate 101. A rotating gear 702 is fixedly connected to the rotating shaft of the fifth motor 701. A second rack 703 is meshed and connected to the inner side of the rotating gear 702. The back surface of the second rack 703 is fixedly connected to the placing component 8.

[0043] In this embodiment, it should be specifically noted that: when the workpiece to be ground 10 is kept flat in the horizontal direction under the monitoring of the distance measuring plate 6, then the fifth motor 701 is started. The fifth motor 701 drives the rotating gear 702 to rotate. The rotating gear 702 drives the second rack 703 engaged with it to move outwards. At this time, the workpiece to be ground 10 is longitudinally tensioned under the pulling between the punching and tensioning component 9 and the feeding component 3 inside the placing component 8 until it is kept flat in the longitudinal direction under the detection of the distance measuring plate 6.

[0044] Refer to Figures 2 - 4 , the placing component 8 includes two guiding boxes 801. The guiding boxes 801 are mirror-symmetrical to each other. The front ends of the guiding boxes 801 are aligned with the gap between the pressing roller 304 and the lower winding roller 307. A blocking box 802 is provided at the rear ends of the two guiding boxes 801. A T-shaped guide rail 803 is slidably connected to the bottom of the blocking box 802. The bottom of the T-shaped guide rail 803 is fixedly connected to the top of the base plate 101.

[0045] In this embodiment, it should be specifically explained that the function of the placement component 8 is to guide the workpiece 10 to be ground and serve as a carrier for leveling the workpiece 10 to be ground.

[0046] Reference Figures 4 - 6 The guide box 801 includes a first clamping plate 8011, a first clamping groove 8013 is passed through the side of the first clamping plate 8011, a first mounting hole 8012 is provided on the bottom of the first clamping groove 8013, a first protruding hole 8015 is provided at the bottom of the first protruding hole 8015, a first guide groove 8016 is provided at the bottom, a first mounting groove 8017 is provided on the side of the first guide groove 8016, a threaded hole 8014 is provided at the bottom of the first clamping groove 8013, and the threaded hole 8014 is spirally connected to the screw 504 to prevent The blocking box 802 includes a second clamping plate 8021, a second clamping groove 8023 passes through the side of the second clamping plate 8021, a second mounting hole 8022 is provided on the bottom of the second clamping groove 8023, a second protruding hole 8025 is provided at the bottom of the second protruding hole 8025, a second guide groove 8026 is provided at the bottom, a second mounting groove 8027 is provided on the side of the second guide groove 8026, a second T-slot 8024 is provided at the bottom of the second clamping groove 8023, and the second T-slot 8024 is slidably connected to the T-shaped guide rail 803.

[0047] In this embodiment, it should be specifically explained that: when the workpiece 10 to be ground enters the first clamping groove 8013 of the guide boxes 801 on both sides and moves therein, since the thickness of the first clamping groove 8013 is the same as that of the workpiece 10 to be ground, the workpiece 10 to be ground can maintain a relatively flat state, and finally the front part of the workpiece 10 to be ground reaches the inside of the second clamping groove 8023 of the blocking box 802.

[0048] Reference Figure 3 and Figure 9 The punching tensioning assembly 9 includes a second cylinder 901, the housing of the second cylinder 901 is fixedly connected to the side walls of the first mounting groove 8017 and the second mounting groove 8027, the top of the piston rod of the second cylinder 901 is fixedly connected to a moving block 902, the outer side of the moving block 902 is fixedly connected to a downwardly inclined downward hook 903, the first protruding hole 8015 and the second protruding hole 8025 are slidably connected to a hook column cylinder 904, the outer side of the hook column cylinder 904 is fixed A guide ring 907 is fixedly connected, and the inner walls of the second guide groove 8026 and the first guide groove 8016 are slidably connected with the guide ring 907.

The side wall of the hook column cylinder 904 is fixedly connected with an upward oblique hook 905, and the oblique upper hook 905 is parallel to the oblique lower hook 903 and is connected in conflict with each other.

[0049] In this embodiment, it should be specifically noted that: start the punching machine 908 to punch the workpiece 10 to be ground. After the punching is completed, start the second cylinders 901 at both ends inside the guiding box 801 and the blocking box 802. The piston rods of the second cylinders 901 drive the moving blocks 902 and the downward-inclined barbs 903 to move backward. During the backward movement of the downward-inclined barbs 903, the downward-inclined barbs 903 press the upward-inclined barbs 905 and the hook column cylinder 904 to descend. When the downward-inclined barbs 903 are completely disengaged from the upward-inclined barbs 905, the hook column cylinder 904 and the guiding ring 907 rise through the punching hole on the workpiece 10 to be ground under the action of the spring 906, and the hook column cylinder 904 contacts the tops of the second clamping groove 8023 and the first clamping groove 8013 to complete the fixation of the workpiece 10 to be ground. After the detection is completed, the punching rod of the punching machine 908 extends to press the hook column cylinder 904 to the bottom. Subsequently, the piston rod of the second cylinder 901 pushes the moving block 902 and the downward-inclined barb 903 close to the hook column cylinder 904 until the corresponding downward-inclined barb 903 is located above the corresponding upward-inclined barb 905. Subsequently, the punching rod of the punching machine 908 retracts, and the hook column cylinder 904 rises under the elastic action of the spring 906. Subsequently, the hook column cylinder 904 and the upward-inclined barb 905 stop moving under the blocking action of the downward-inclined barb 903, and the first cylinder 303 drives the pressing roller 304 to rise, and the fixation of the workpiece 10 to be ground is released.

[0050] The working principle of the present invention:

[0051] The main problem solved in this embodiment is: by utilizing the initiative of the second motor 408 and the third motor 409, the number of grinding heads 403 extending out of the rotating box 401 is changed, realizing the change of the mechanical structure, thereby changing the grinding frequency of the grinding component 4, and utilizing the clamping and friction of the first cylinder 303 and the lower winding roller 307 on the workpiece 10 to be ground, realizing the automatic wear resistance test of the grinding component 4.

[0052] The specific steps are as follows:

[0053] First, pass the workpiece 10 to be ground through the gap between the pressing roller 304 and the lower winding roller 307, start the first cylinder 303, the first cylinder 303 pushes the pressing roller 304 to descend to clamp the workpiece 10 to be ground, start the first motor 306, the first motor 306 drives the lower winding roller 307 to rotate, the rotation of the lower winding roller 307 drives the workpiece 10 to move to the right. Subsequently, the workpiece 10 to be ground enters the first clamping groove 8013 of the guiding boxes 801 on both sides and moves therein. Since the thickness of the first clamping groove 8013 is the same as that of the workpiece 10 to be ground, the workpiece 10 to be ground can maintain a relatively flat state. Finally, the front part of the workpiece 10 to be ground reaches the inside of the second clamping groove 8023 of the blocking box 802, and the first motor 306 and the lower winding roller 307 stop rotating. At this time, the first cylinder 303 drives the pressing roller 304 to continue to press down to tightly press the workpiece 10 to be ground;

[0054] Subsequently, start the punching machine 908 to punch the workpiece 10 to be ground. After the punching is completed, start the second cylinders 901 at both ends inside the guiding box 801 and the blocking box 802. The piston rods of the second cylinders 901 drive the moving blocks 902 and the inclined downward barbs 903 to retreat backward. During the backward movement of the inclined downward barbs 903, the inclined downward barbs 903 press the inclined upward barbs 905 and the hook column cylinder body 904 to descend. When the inclined downward barbs 903 are completely separated from the inclined upward barbs 905, the hook column cylinder body 904 and the guiding ring 907 rise through the punching hole on the workpiece 10 to be ground under the action of the spring 906, and the hook column cylinder body 904 contacts the tops of the second clamping groove 8023 and the first clamping groove 8013 to complete the fixation of the workpiece 10 to be ground;

[0055] At this time, the workpiece 10 to be ground is currently in a state where it is not completely flat, but the four corners of the workpiece 10 to be ground are already fixed. Start the fourth motor 501. The fourth motor 501 drives the screw rod 504 to rotate. The screw rod 504 drives the pulley 503 fixedly connected to the screw rod 504 to rotate. The rotation of the pulley 503 drives the pulley 503 and the screw rod 504 at the other end of the transmission belt 505 to rotate through the transmission belt 505. Since the thread directions on both sides of the screw rod 504 are different, the guiding boxes 801 at both ends of the screw rod 504 move away from each other and the moving distances are the same. In this way, until the workpiece 10 to be ground remains flat horizontally under the monitoring of the distance measuring plate 6, then start the fifth motors 701 on both sides of the blocking box 802. The fifth motors 701 drive the rotating gears 702 to rotate. The rotating gears 702 drive the second racks 703 engaged with them to move outward. At this time, the workpiece 10 to be ground is longitudinally tensioned under the pulling between the hook column cylinder body 904 and the feeding assembly 3 inside the blocking box 802 until it remains flat longitudinally under the detection of the distance measuring plate 6;

[0056] Subsequently, start the second motor 408. The second motor 408 drives the driving gear 406 to rotate. The driving gear 406 drives the first rack 405, the force reducing box 404, and the grinding head 403 engaged with it to move outward until they contact the surface of the workpiece 10 to be ground. Start the third motor 409. The third motor 409 drives the rotating rod 407 to rotate. The rotating rod 407 drives the rotating box 401 and the protruding grinding head 403 to rotate. The grinding head 403 continuously frictional contacts the surface of the workpiece 10 to be ground. After reaching the threshold time, check whether the wear degree of the workpiece 10 to be ground is qualified. If you want to change the grinding frequency of the grinding head 403, just start multiple second motors 408, extend multiple grinding heads 403 to contact the workpiece 10 to be ground. At this time, the extended lengths of the multiple grinding heads 403 should be the same;

[0057] After the detection is completed, the punching rod of the punching machine 908 extends to press the hook column cylinder body 904 to the bottommost position. Subsequently, the piston rod of the second cylinder 901 pushes the moving block 902 and the downward inclined barb 903 close to the hook column cylinder body 904 until the corresponding downward inclined barb 903 is located above the corresponding upward inclined barb 905. Subsequently, the punching rod of the punching machine 908 retracts, and the hook column cylinder body 904 rises under the elastic action of the spring 906. Then, the hook column cylinder body 904 and the upward inclined barb 905 stop moving under the blocking action of the downward inclined barb 903. The first cylinder 303 drives the pressure roller 304 to rise, and the fixation of the workpiece 10 to be ground is released;

[0058] Subsequently, the electric mechanical claw 203 moves to directly above the workpiece 10 to be ground. The electric telescopic rod 202 gradually extends until the electric mechanical claw 203 contacts the workpiece 10 to be ground. After the electric mechanical claw 203 grabs the workpiece 10 to be ground whose fixation has been released, it moves to directly above the pit 104. The electric mechanical claw 203 releases the workpiece 10 to be ground, and the workpiece 10 to be ground falls into the pit 104.

[0059] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
