Abstract

This invention discloses a method for manufacturing anti-slip children's shoes, relating to the field of anti-slip children's shoe production technology. The manufacturing process comprises a testing platform, a dynamic abrasive unit, a segmented control contact mechanism, and an asynchronous linkage mechanism. The dynamic abrasive unit automatically adjusts and changes the coefficient of friction during abrasion resistance testing. A shoe sole block is mounted on the right side of the trigger component. A cooperating unit works with the trigger component to move the shoe sole block, pushing against the foot area of ​​the shoe sole to contact the dynamic abrasive unit for testing.

Furthermore, by simulating the actual wear under heel-first and forefoot-first gait conditions through reciprocating oscillation, the invention improves the accuracy, representativeness, and data quality of the test, making the test results more practically meaningful.

Description

Technical Field

[0001] This invention relates to the field of anti-slip children's shoe manufacturing technology, specifically to a method for preparing anti-slip children's shoes. Background Technology

[0002] Anti-slip children's shoes are shoes specially designed for children. Their main feature is excellent anti-slip performance, which ensures greater safety for children when walking or running. The manufacturing process of anti-slip children's shoes generally includes steps such as material cutting, sole making, upper making, bonding, and quality inspection. Among these steps, quality inspection is the most critical step in verifying the quality of anti-slip children's shoes, and the abrasion resistance test is the most important performance test. The sole needs to have good abrasion resistance, which can significantly extend the service life of anti-slip children's shoes.

[0003] During daily walking, different areas of the sole of a shoe will show different wear patterns due to varying frequencies and forces of contact with the ground. Typical wear patterns in different areas of the sole during shoe use are as follows: The forefoot area is usually the most severely worn part of the sole because when walking, the foot lands first on the ball of the foot, then gradually transfers weight to the forefoot, and finally pushes off the ground with the balls of the feet. This process results in the forefoot area bearing significant pressure and friction. The heel area is also a relatively worn part of the sole. Many people habitually land on their heels first when walking, and the impact force during this phase of contact with the ground causes the heel area to bear significant friction, especially the outer part of the heel, resulting in more noticeable wear on the outer side of the heel. The midfoot area, i.e., the arch area, usually wears less because this part does not directly contact the ground during walking. When walking and running, the arch area is located in the arched part of the sole and usually does not directly bear the body weight, therefore the friction with the ground is relatively small.

[0004] However, traditional tests usually test the wear of a uniform area of ​​the sole, focusing only on the overall wear of the sole and ignoring the specific wear characteristics of areas such as the forefoot, arch, and heel. In real walking, the wear of different areas of the sole is uneven, and it is not possible to conduct targeted tests based on the wear of each area of ​​the sole, thus failing to accurately reflect the specific wear resistance of each area of ​​the sole. Summary of the Invention

[0005] This invention provides a method for preparing anti-slip children's shoes, which solves the problem that traditional shoe sole abrasion tests usually only target uniform areas of the sole, focusing on the overall wear amount, while ignoring the specific wear characteristics of parts such as the forefoot, arch, and heel. Since the wear of different areas of the sole is uneven during walking, this test method cannot accurately assess the wear of each area, thus failing to accurately reflect the specific abrasion resistance of each part of the sole.

[0006] This invention provides a method for preparing anti-slip children's shoes. The specific steps of the method are as follows:

[0007] S1. Material Cutting: Cut various materials needed for the shoe upper and sole according to the design drawings.

[0008] S2. Sole manufacturing: Anti-slip children's shoe soles are made using molds and injection molding technology.

[0009] S3. Upper making: Use a sewing machine to sew the upper material into shape.

[0010] S4. Adhesive connection: The sewn upper is connected to the non-slip children's sole by adhesive to obtain non-slip children's shoes.

[0011] S5. Quality Inspection: The quality of non-slip children's shoes is inspected by combining a regional control mechanism with a dynamic abrasive section.

[0012] The preparation method of the anti-slip children's shoes in steps S1-S5 above needs to be completed by the cooperation of a test bench, a dynamic abrasive section, a domain-controlled touch mechanism, and an asynchronous linkage mechanism.

[0013] A dynamic abrasive unit is installed on the upper part of the testing platform. A segmented contact mechanism is installed on the upper surface of the testing platform to respectively move the forefoot, arch, and heel areas of the anti-slip children's shoe sole, allowing different areas of the shoe sole to sequentially contact and engage with the dynamic abrasive unit for abrasion resistance testing of different areas. The dynamic abrasive unit automatically adjusts and changes the coefficient of friction during the abrasion resistance test of the anti-slip children's shoe. An asynchronous linkage mechanism is provided at the rear of the upper surface of the testing platform to link the dynamic abrasive unit and the segmented contact mechanism, making their movements asynchronous to further enhance the test friction. The segmented contact mechanism includes a support fixedly connected to the upper surface of the testing platform, a bearing shaft rotatably connected through the support, a mounting plate fixedly connected to the front end of the bearing shaft, two symmetrically rotatably connected left and right to the front end of the mounting plate, and a fixed connection to the front of the rotating shaft. The shoe comprises a mounting rod with a hollow interior, a tension spring fixedly connected between the mounting rod and the mounting plate by a fixing strip, two actuating components respectively disposed in the mounting rod, a shoe-mounted actuating component disposed in the middle of the mounting plate for cooperating with the two mounting rods to push against the arch area of ​​the anti-slip children's shoe sole to contact the dynamic abrasive part, and a cooperating unit disposed between the shoe-mounted actuating component and the actuating component. The left actuating component has a heel block installed on its left side, and the cooperating unit is used to cooperate with the left actuating component to drive the heel block to move and push against the heel of the anti-slip children's shoe to contact the dynamic abrasive part for testing. The right actuating component has a toe block installed on its right side, and the cooperating unit is used to cooperate with the right actuating component to drive the toe block to move and push against the toe area of ​​the anti-slip children's shoe sole to contact the dynamic abrasive part for testing.

[0014] In one possible implementation, the dynamic abrasive unit includes two symmetrically slidably connected electric sliders on the upper surface of the test platform and a friction plate fixedly connected to the two electric sliders. Sliding rods are symmetrically slidably connected to the lower surface of the friction plate, and a strip plate is slidably connected to the outside of the two sliding rods. Several strip-shaped slots are equidistantly formed on the friction plate. Several strip-shaped friction blocks corresponding to the strip-shaped slots are equidistantly fixed to the upper surface of the strip plate via fixing blocks. A sliding groove is formed on the upper surface of the test platform, and a sliding seat is slidably connected in the groove. Abutment blocks that abut against the groove wall are slidably connected to the front and rear sides of the sliding seat via spring telescopic columns. A connecting rod is hinged between the sliding seat and the strip plate.

[0015] In one possible implementation, a cleaning mechanism for cleaning the surfaces of the friction plate and the strip friction block is installed between the friction plate and the test platform. The cleaning mechanism includes several supports that are equidistantly fixed to the lower end face of the friction plate and correspond to the strip friction block. Several levers are equidistantly hinged to the lower end face of the supports. Flexible strip brushes are fixedly connected to the left side of each lever. Push rods are hinged to the right side of the levers located on the same side at the front and back. Limiting springs are fixedly connected between the push rods and the friction plate. A folded plate that cooperates with the push rod is fixedly connected to the rear of the upper end face of the test platform. A strip duct with a front opening is fixedly connected to the upper end face of the folded plate.

[0016] In one possible implementation, the shoe-mounted actuation assembly includes a slip ring fixedly connected to the front end face of the mounting plate via a connecting post. A sliding rod is slidably connected in the slip ring. A spring telescopic rod is pivotally hinged to the lower part of the sliding rod. An arc-shaped elastic top plate is hinged to the lower ends of the two spring telescopic rods. Gears are fixedly connected to the outside of the two rotating shafts. Two racks that mesh with the gears are symmetrically fixedly connected to the upper end of the sliding rod via a T-shaped plate.

[0017] In one possible implementation, the actuating component includes a rectangular through slot formed on the side wall of the mounting rod away from the sliding rod. A pull plate is hinged between the front and rear walls of the rectangular through slot via a pivot. A rod ring is fixedly connected to the inner cavity of the mounting rod via a crossbar. A pull rod is slidably connected in the rod ring. A return spring is fixedly connected between the upper end of the pull rod and the upper cavity wall of the mounting rod. A C-shaped frame is fixedly connected to the lower end of the pull rod. Waist-shaped slots are formed on the front and rear sides of the pull plate. A sliding column is fixedly connected to the vertical section of the C-shaped frame and slidably connected in the waist-shaped slot. The heel block is fixedly connected to the left side of the pull plate located on the left side, and the sole block is fixedly connected to the right side of the pull plate located on the right side.

[0018] In one possible implementation, the mating unit includes a horizontal bar plate fixedly connected to the front end face of the sliding rod via a connecting block. The horizontal bar plate has symmetrically formed grooves on the left and right sides. The front wall panel of the mounting rod has a vertical through groove. The front part of the pull rod is fixedly connected to a push post. The front end of the push post passes through the vertical through groove and is slidably connected in the groove.

[0019] In one possible implementation, the asynchronous linkage mechanism includes a transmission wheel rotatably connected to the rear end of the bearing shaft, and an abutment strip that abuts against the outer wall of the transmission wheel is fixedly connected to the friction plate by an L-shaped rod.

[0020] In one possible implementation, a number of elastic columns are fixedly connected at equal intervals to the arc-shaped outer wall of the heel block, and the elastic columns gradually tilt from top to bottom toward the side away from the heel block.

[0021] As can be seen from the above technical solutions, the present invention has the following advantages:

[0022] In this invention, the anti-slip children's shoe is bent into three sections by a regional control touch mechanism, so that the forefoot area, midfoot area and heel area of ​​the sole can be tested separately. The regional targeted testing method can obtain more detailed wear data. Then, through the reciprocating swing during the test, the sole contacts the friction plate in two ways: heel-first contact and ball-first contact. This can more realistically simulate the actual wear of each area of ​​the sole under the two different states of heel-first and ball-first contact, making the test results more representative and improving the accuracy, representativeness and data quality of the test.

[0023] In this invention, the overall roughness of the friction plate surface is automatically adjusted by combining the friction plate and the strip friction block during the testing of anti-slip children's shoes, thereby simulating the friction changes when walking on different ground surfaces. Multiple different wear scenarios can be simulated in the same test, making the test more comprehensive and better reproducing the wear process of the sole in various environments, providing more realistic test results.

[0024] In this invention, the cleaning mechanism automatically cleans the surfaces of the friction plate and the strip friction block during testing, avoiding the accumulation of debris generated during testing that alters the surface conditions of the friction plate and the friction block and affects the accuracy of the test. This maintains the original state of the friction surfaces, ensuring the consistency of test conditions each time, thereby improving the accuracy and repeatability of the test results.

[0038] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] Please see Figure 1 , Figure 2 and Figure 3 This invention provides a technical solution: a method for preparing anti-slip children's shoes, the specific steps of which are as follows:

[0040] S1. Material Cutting: Cut various materials needed for the shoe upper and sole according to the design drawings.

[0041] S2. Sole manufacturing: Anti-slip children's shoe soles are made using molds and injection molding technology.

[0042] S3. Upper making: Use a sewing machine to sew the upper material into shape.

[0043] S4. Adhesive connection: The sewn upper is connected to the non-slip children's sole by adhesive to obtain non-slip children's shoes.

[0044] S5. Quality Inspection: The anti-slip children's shoes are inspected by combining the regional control mechanism 3 and the dynamic abrasive part 2.

[0045] The preparation method of the anti-slip children's shoes in steps S1-S5 above needs to be completed by the cooperation of the test platform 1, the dynamic abrasive part 2, the regional control touch mechanism 3 and the asynchronous linkage mechanism 4.

[0046] A dynamic abrasive unit 2 is installed on the upper part of the test platform 1. A domain-controlled contact mechanism 3 is installed on the upper surface of the test platform 1 to push the forefoot area, arch area and heel area of ​​the anti-slip children's shoe respectively so that different areas of the sole of the anti-slip children's shoe come into contact with the dynamic abrasive unit 2 in sequence, so as to conduct abrasion resistance tests on different areas. The dynamic abrasive unit 2 is used to automatically adjust and change the friction coefficient during the abrasion resistance test of the anti-slip children's shoe. An asynchronous linkage mechanism 4 is provided at the rear of the upper surface of the test platform 1 to link the dynamic abrasive unit 2 and the domain-controlled contact mechanism 3 so that their movements are asynchronous and further enhance the amount of friction tested.

[0047] Please see Figure 2 , Figure 3 and Figure 4 In this embodiment, the domain-type control mechanism 3 includes a support 31 fixedly connected to the upper surface of the test platform 1, a bearing shaft 32 rotatably connected through the support 31, a mounting plate 33 fixedly connected to the front end of the bearing shaft 32, two rotating shafts 34 rotatably connected to the front end of the mounting plate 33, a mounting rod 35 fixedly connected to the front end of the rotating shaft 34 and having an internal cavity, a tension spring 36 fixedly connected between the mounting rod 35 and the mounting plate 33 by a fixing strip, two touch components 37 respectively disposed in the mounting rod 35, a shoe-mounted push component 38 disposed in the middle of the mounting plate 33 for cooperating with the two mounting rods 35 to push against the arch area of ​​the anti-slip children's shoe sole to contact the dynamic abrasive part 2, and a cooperating unit 39 disposed between the shoe-mounted push component 38 and the touch component 37.

[0048] Please see Figure 4 and Figure 5The left-side actuating component 37 has a heel block 310 mounted on its left side. A mating unit 39 engages with the left-side actuating component 37 to move the heel block 310, pushing against the heel of the anti-slip children's shoe to contact the dynamic abrasive unit 2 for testing. The right-side actuating component 37 has a sole block 311 mounted on its right side. The mating unit 39 engages with the right-side actuating component 37 to move the sole block 311, pushing against the sole and forefoot area of ​​the anti-slip children's shoe to contact the dynamic abrasive unit 2. In the contact test of part 2, several elastic pillars 6 are fixedly connected at equal intervals on the arc-shaped outer wall of the heel block 310. The elastic pillars 6 gradually tilt away from the heel block 310 from top to bottom. When the heel block 310 is inserted into the heel of the anti-slip children's shoe, the elastic pillars 6 press against the inner wall of the anti-slip children's shoe to increase the friction between the two. This makes it easier for the heel block 310 to lift and bend the heel area of ​​the anti-slip children's shoe, and avoids the situation where the heel block 310 separates from the anti-slip children's shoe during the lifting process.

[0049] Please see Figure 4 and Figure 5 The shoe-mounted actuation assembly 38 includes a slip ring 381 fixedly connected to the front end face of the mounting plate 33 via a connecting post. A sliding rod 382 is slidably connected in the slip ring 381. A spring telescopic rod 383 is pivotally hinged to the lower part of the sliding rod 382. An arc-shaped elastic top plate 384 is hinged to the lower ends of the two spring telescopic rods 383. Gears 385 are fixedly connected to the outside of the two rotating shafts 34. Two racks 386 that mesh with the gears 385 are symmetrically fixedly connected to the upper end of the sliding rod 382 via a T-shaped plate.

[0050] Please see Figure 4 , Figure 5 and Figure 6 The trigger component 37 includes a rectangular through groove 371 on the side wall of the mounting rod 35 away from the sliding rod 382. A pull plate 372 is hinged between the front and rear walls of the rectangular through groove 371 via a pivot. A rod ring is fixedly connected to the inner cavity of the mounting rod 35 via a horizontal bar. A pull rod 373 is slidably connected in the rod ring. A return spring 374 is fixedly connected between the upper end of the pull rod 373 and the upper cavity wall of the mounting rod 35. A C-shaped frame 375 is fixedly connected to the lower end of the pull rod 373. Waist-shaped grooves 376 are provided on the front and rear sides of the pull plate 372. A sliding column 377 is fixedly connected to the vertical section of the C-shaped frame 375 and slidably connected in the waist-shaped groove 376. A heel block 310 is fixedly connected to the left side of the pull plate 372 located on the left side. A sole block 311 is fixedly connected to the right side of the pull plate 372 located on the right side.

[0051] Please see Figure 4 and Figure 5The cooperating unit 39 includes a horizontal strip plate 391 fixedly connected to the front end face of the sliding rod 382 via a connecting block. The horizontal strip plate 391 has symmetrically opened strip grooves 392 on the left and right sides. The front wall panel of the mounting rod 35 has a vertical through groove. The front part of the pull rod 373 is fixedly connected to a deflector 393. The front end of the deflector 393 passes through the vertical through groove and is slidably connected in the strip groove 392.

[0052] The initial state of the two mounting rods 35 in the domain-type control mechanism 3 is as follows: under the pull of the tension spring 36, the two mounting rods 35 are arranged in an inverted V shape. Before conducting the wear resistance test on the anti-slip children's shoes, the tongue of the anti-slip children's shoes is first lifted. Then, the two mounting rods 35 are pinched and rotated around the pivot point 34 until the two mounting rods 35 move to a position parallel to each other. Then, the anti-slip children's shoes are put on the outside of the heel block 310 and the sole block 311, so that the sole block 311 extends into the sole cavity of the anti-slip children's shoes, and the heel block 310 extends into the heel cavity area of ​​the anti-slip children's shoes.

[0053] Then, the pinched mounting rod 35 is released, and the tension spring 36 returns to its original position, pulling the two mounting rods 35 away from each other around the pivot 34, causing the pivot 34 to rotate. The pivot 34 then drives the gear 385 to rotate, and the gear 385 drives the rack 386 to move downward. The rack 386 then drives the sliding rod 382 to move downward through the T-shaped plate. The sliding rod 382 then drives the arc-shaped elastic top plate 384 to move downward through the spring telescopic rod 383, so that the arc-shaped elastic top plate 384 abuts against the middle of the anti-slip children's shoe. While the two mounting rods 35 are rotating away from each other, they also drive the heel block 310 and the toe block 311 to move away from each other. The heel block 310 and the toe block 311 abut against the inner cavity of the anti-slip children's shoe, respectively, causing the anti-slip children's shoe to bend upward around the arc-shaped elastic top plate 384.

[0054] As the sliding rod 382 moves downward, it also causes the horizontal bar 391 to move downward. The downward movement of the horizontal bar 391 then presses down the shifter 393, which in turn causes the pull rod 373 to move downward. The pull rod 373 then, through the C-shaped frame 375, causes the sliding column 377 to move downward. The sliding column 377 then presses down the waist-shaped groove 376, causing the pull plate 372 to rotate around the rotating column. The pull plate 372 on the right side causes the shoe sole block 311 to rotate counterclockwise around the rotating column, while the pull plate 372 on the left side causes the heel block 310 to rotate clockwise around the rotating column. After rotation, the shoe... The heel block 310 and the sole block 311 further bend the anti-slip children's shoe, causing it to bend into a "\_ / " shape. Then, the dynamic abrasive unit 2 can be controlled to operate, and the bearing shaft 32 can be driven to swing back and forth through the asynchronous linkage mechanism 4. The bearing shaft 32 then drives the anti-slip children's shoe to swing back and forth through the mounting plate 33 and the mounting rod 35. During the back and forth swing, the sole, midfoot area, and heel area of ​​the anti-slip children's shoe come into contact with the dynamic abrasive unit 2, so that targeted wear resistance tests can be performed on different areas of the sole of the anti-slip children's shoe.

[0055] Please see Figure 2 , Figure 3 , Figure 7 and Figure 9 In this embodiment, the dynamic abrasive unit 2 includes two symmetrically slidably connected electric sliders 21 on the upper surface of the test platform 1 and friction plates 22 fixedly connected to the two electric sliders 21. Sliding rods 23 are symmetrically slidably connected to the lower surface of the friction plates 22. Strip plates 24 are slidably connected to the outside of the two sliding rods 23. Several strip grooves 25 are equidistantly opened on the friction plates 22. Several strip friction blocks 26 corresponding to the strip grooves 25 are fixedly connected to the upper surface of the strip plates 24 by fixing blocks at equal intervals. A sliding groove is opened on the upper surface of the test platform 1. A sliding seat 27 is slidably connected in the sliding groove. Abutment blocks 28 that abut against the groove wall are slidably connected to the front and rear sides of the sliding seat 27 by spring telescopic columns. A connecting rod 29 is hinged between the sliding seat 27 and the strip plate 24. The asynchronous linkage mechanism 4 includes a transmission wheel 41 rotatably connected to the rear end of the bearing shaft 32. An abutment strip 42 that abuts against the outer wall of the transmission wheel 41 is fixedly connected to the friction plate 22 by an L-shaped rod.

[0056] The electric slider 21 moves laterally back and forth, causing the friction plate 22 to move laterally back and forth as well. During this movement, the friction plate 22, via the L-shaped rod, drives the contact strip 42 to move synchronously. The contact strip 42 then drives the transmission wheel 41 to rotate, which in turn drives the transmission shaft to rotate. The transmission shaft, via the mounting plate 33 and mounting rod 35, causes the anti-slip children's shoe to swing back and forth. During this swinging motion, when the friction plate 22 moves to the left, the anti-slip children's shoe swings clockwise. At this time, the heel area, midfoot area, and sole area of ​​the anti-slip children's shoe successively contact the friction plate 22. On the upper surface, during this process, the heel part first contacts the surface of the friction plate 22, and the edge of the heel part of the shoe collides with the surface of the friction plate 22, thus simulating the wear test of the sole when the heel contacts the ground first. When the friction plate 22 moves to the right, it causes the anti-slip children's shoe to swing counterclockwise. At this time, the sole area, midfoot area and heel area of ​​the anti-slip children's shoe contact the surface of the friction plate 22 in turn, thus simulating the abrasion test when the forefoot lands first. This allows for separate abrasion tests on the sole area, midfoot area and heel area of ​​the anti-slip children's shoe.

[0057] As the friction plate 22 moves laterally back and forth, it also pushes the slide block 27 to move synchronously via the connecting rod 29. When the friction plate 22 moves to the left, the spring telescopic column pushes the stop block 28 against the groove wall, resulting in a certain frictional resistance between the slide block 27 and the groove. When the friction plate 22 moves to the left, it applies pressure to the inclined connecting rod 29. Then, the connecting rod 29 pushes the strip plate 24 upward, and the strip plate 24 then drives the strip friction block 26 upward into the strip through groove 25. The roughness of the upper surface of the strip friction block 26 is greater than that of the upper surface of the friction plate 22. The surface roughness is such that when the strip friction block 26 moves completely upward into the strip through groove 25, the friction coefficient of the upper surface of the friction plate 22 will increase as a whole. When the friction plate 22 moves to the right, the friction plate 22 will pull the slide block 27 to the right through the connecting rod 29. At this time, the connecting rod 29 drives the strip plate 24 to move downward, and the strip plate 24 then drives the strip friction block 26 to move out of the strip through groove 25. This will make the friction coefficient of the upper surface of the friction plate 22 return to the initial value, thereby automatically adjusting the friction coefficient of the friction plate 22 for the anti-slip children's shoes by moving laterally back and forth.

[0058] The automatic adjustment of the surface roughness of the friction plate 22 can more accurately simulate the actual wear and tear of children walking on different surfaces. Since different surfaces have different roughness, the automatic adjustment of the surface roughness coefficient of the friction plate 22 can better reproduce the wear process of the sole in various environments and provide more realistic test results.

[0059] After testing the anti-slip children's shoes, control the dynamic abrasive section 2 and the regional control touch mechanism 3 to stop operating. Then, squeeze the two mounting rods 35 again to bring them closer together and rotate them, causing the sole block 311 and the heel block 310 to move closer together. Then, the tested anti-slip children's shoes can be removed, and the wear of the sole area, midfoot area and heel area can be observed to test the wear resistance of the anti-slip children's shoe sole.

[0060] Please see Figure 2 , Figure 7 and Figure 8 In this embodiment, a cleaning mechanism 5 for cleaning the surfaces of the friction plate 22 and the strip friction block 26 is installed between the friction plate 22 and the test platform 1. The cleaning mechanism 5 includes several supports 51 that are fixedly connected at equal intervals to the lower end face of the friction plate 22 and correspond to the strip friction block 26. Several levers 52 are hinged at equal intervals to the lower end face of the supports 51. Flexible strip brushes 53 are fixedly connected to the left side of the levers 52 respectively. Push rods 54 are hinged to the right side of the levers 52 located on the same side at the front and back. Limiting springs 55 are fixedly connected between the push rods 54 and the friction plate 22. A folded plate 56 that cooperates with the push rod 54 is fixedly connected to the rear part of the upper end face of the test platform 1. A strip air duct 57 with a front opening is fixedly connected to the upper end face of the folded plate 56.

[0061] The lever 52 is initially arranged at an angle, so the flexible strip brush 53 is also arranged at an angle to prevent obstruction and interference when the strip friction block 26 moves upward. The friction plate 22 moves laterally back and forth, which also triggers the cleaning mechanism 5. After the friction plate 22 moves to the left, it moves to the right and drives the strip friction block 26 to move downward. Then, the friction plate 22 drives the push rod 54 to abut against the folded plate 56. The push rod 54 then moves along the inclined surface of the folded plate 56 and is pushed back and forth. The push rod 54 then drives the flexible strip brush 53 to swing back and forth through the lever 52. During the back and forth swinging process, the flexible strip brush 53 will sweep back and forth on the surface of the downward-moving strip friction block 26. This allows for the timely removal of debris that falls onto the surface of the strip friction block 26 during the testing of children's shoe soles. Simultaneously, the strip air duct 57 is controlled to blow air forward, allowing the airflow to pass over the upper surface of the friction plate 22, thereby cleaning the debris on the surface of the friction plate 22. This ensures that debris generated during testing is cleaned up in a timely manner, guaranteeing the cleanliness of the surfaces of the friction plate 22 and the strip friction block 26 during testing. When the friction plate 22 moves to the left, the push rod 54, which is driven to push against the folded plate 56, will also indirectly drive the flexible strip brush 53 to swing back and forth. Since the strip friction block 26 moves upward into the strip through groove 25 at this time, the flexible strip brush 53 will swing back and forth below the strip friction block 26.
