Description

Technical Field

[0001] The invention relates to the technical field of sole testing, in particular to a system and method for testing the wear resistance of a rubber sole. Background Art

[0002] In the field of shoe manufacturing, rubber soles are widely used in various types of shoes, including sports shoes, casual shoes, work shoes, etc. The wear resistance of the sole is a key indicator of shoe quality. For consumers, wear-resistant soles can ensure that the shoes maintain good performance during long-term wear and reduce shoe damage caused by excessive wear of the soles.

[0003] In the existing sole wear resistance test, most of them place the shoe cover on the shoe shape block, and drive the sole to approach the rotating test roller through the movement of the shoe shape block, so that the bottom of the shoe is tightly attached to the test roller. However, this method is difficult to simulate the state of a person walking. During the walking process, the feet will have a certain degree of movement and flexibility, so that the friction angle between the sole and the ground will change due to factors such as the movement of the footsteps and the change of the body's center of gravity, making it difficult to test the wear resistance of the sole under various possible friction conditions. At the same time, because the test roller will rotate at a high speed during the test, the shoe cover set on the outer surface of the limit frame may rock back and forth left and right with the movement of the test roller, so that the force of the test roller is not on the same part of the sole of the shoe, which causes errors in the sole wear resistance test and inaccurate test results. Summary of the invention

[0004] The purpose of the present invention is to provide a rubber sole wear resistance testing system and a testing method to solve the problems raised in the above background technology.

[0005] To achieve the above object, a rubber sole wear resistance test system is provided, comprising a support frame, a cylindrical rod is arranged on the support frame, shoe-shaped blocks are fixedly connected to both ends of the cylindrical rod, and the two shoe-shaped blocks are symmetrical about the center line of the support frame, and a notch is provided at one end of the two shoe-shaped blocks away from each other, a moving device and a fixing device are arranged inside the cylindrical rod, and a simulation device is arranged below the support frame, and the simulation device is used to test the wear resistance of the sole; When the two shoe-shaped blocks are rotated to a horizontal state, the shoe is put on the shoe-shaped block on the left side, and the moving device is used to support the inner bottom of the shoe so that the pressure outside the sole is evenly distributed. While supporting, the contact friction between the sole and the simulation device can produce multi-angle changes; When the moving device is working, it drives the fixing device to work. The fixing device is used to fix the two sides of the inside of the shoe. During the test, the shoe and the shoe block are closely fitted and kept stable. At the same time, different models of shoes can be tested. The cylindrical rod drives the shoe-shaped block to rotate clockwise.

[0010] As a further improvement of the present technical solution, the simulation device includes a mounting seat fixedly connected to the lower side of the support frame, a test plate is arranged on the upper side of the mounting seat, a slide groove is opened on the upper side of the mounting seat, a fixing rod is fixedly connected to the inside of the mounting seat, a slider is slidably connected to the outside of the fixing rod, the upper end of the slider passes through the slide groove and is fixedly connected to the lower side of the test plate, when the sole contacts and rubs against the test plate, the sole drives the test plate to move, and the movement of the test plate drives the slider to move on the fixed rod.

[0011] As a further improvement of the present technical solution, a compression spring is fixedly connected to the inner wall of the mounting seat on one side of the slider, and the compression spring is sleeved on the fixed rod. A button is fixedly connected to the side of the inner part of the slide groove away from the slider. The slider moves toward the button and squeezes the compression spring, and the compression spring drives the test plate to reset.

[0012] As a further improvement of the present technical solution, an L-shaped rod is fixedly connected to the movable rod, and the L-shaped rod passes through one side of the cylindrical rod. A support plate is fixedly connected to the outer wall of the cylindrical rod. The interior of the support plate is slidingly connected to the upper side of the L-shaped rod, and the lower side of the L-shaped rod is fixedly connected to a side plate. A servo motor is fixedly connected to one side of the support plate, and the output end of the servo motor is rotatably connected to a rotating rod, and the other end of the rotating rod is slidably connected to the interior of the side plate.

[0013] As a further improvement of the present technical solution, tension springs are fixedly connected to the inner wall of the cylindrical rod on both sides of the lower end of the L-shaped rod, and the tension springs are sleeved on the movable rod. The upper sides of the L-shaped rod and the support plate are fixedly connected to pillars, and an extrusion spring is fixedly connected between the two pillars.

[0014] The second object of the present invention is to provide a method for operating the above-mentioned rubber sole wear resistance testing system to test wear resistance, comprising the following method steps: S1. First, when the shoe block rotates to a horizontal state, a shoe cover is placed on the shoe block on the left side, and the moving device moves toward the shoe block on the left side to support the inner bottom of the shoe on the left side. At this time, the moving device does not support the shoe on the shoe block on the right side. While supporting, the moving device drives the shoe sole to contact with the simulation device to produce multi-angle changes; S2, the moving device then drives the fixing device to rotate while moving, and the fixing device rotates to fix the two sides of the inside of the shoe. During the test, the shoe and the shoe block fit tightly and remain stable, and different models of shoes can be tested at the same time; S3. The shoe-shaped block is driven to rotate clockwise by the cylindrical rod. The rotation of the shoe-shaped block drives the contact and friction with the simulation device to simulate a real walking scene. During the friction, the shoe-shaped block drives the simulation device to move. The wear resistance of the sole can be judged according to the moving position of the simulation device.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In the rubber sole wear resistance testing system and testing method, the rotating rod is rotated to drive the moving rod to move toward the shoe-shaped block on the left side. When the moving rod moves, it drives the two top plates to move in the same direction, so that the top plate supports the bottom of the left shoe, and can evenly disperse the pressure applied to the outside of the sole during the test to the inside of the sole, so that the entire sole can participate in the friction process during the test, and the wear resistance of the sole can be more comprehensively evaluated. At the same time, the top plate can slide while supporting, which can cause multi-angle changes when the sole contacts and rubs with the test plate, thereby more comprehensively examining the wear resistance of the sole under various possible friction conditions.

[0016] 2. In the rubber sole wear resistance testing system and testing method, when the top plate is driven by the moving rod to support the bottom of the shoe on the left side, the moving rod drives the two rotating blocks to rotate one side of the shoe-shaped block to the outside on both sides. The rotating blocks are used to fix the two sides of the inside of the shoe, ensuring that the shoe and the shoe-shaped block are tightly fitted and stable during the test, better reflecting the stress conditions of the sole during actual wearing, preventing the sole from displacement or shaking during the test, resulting in certain areas of the sole being unable to contact the simulation device, and at the same time, different types of shoes can be tested, thereby improving the practical effect of the device.

[0017] 3. In the rubber sole wear resistance testing system and method, the driving motor is started to drive the two shoe-shaped blocks to rotate clockwise, and the shoe-shaped blocks drive the soles to contact and rub against the test plates, which is used to simulate a real walking scene. The test plates are driven to move by the soles. When the test plates drive the sliders to touch the buttons, it indicates that the shoes have good wear resistance. If the buttons cannot be touched, it indicates that the shoes have average wear resistance. The wear resistance of the soles is judged according to the moving positions of the test plates. The residence time and movement paths of the test plates at different positions of the soles can be clearly observed, thereby improving the testing efficiency of the soles.

While supporting, the contact friction between the sole and the simulation device 4 can produce multi-angle changes; When the moving device 2 is working, the fixing device 3 is driven to work. The fixing device 3 is used to fix the two sides of the inside of the shoe. During the test, the shoe and the shoe-shaped block 12 are closely fitted and kept stable, ensuring that the shoe and the shoe-shaped block 12 are closely fitted and kept stable during the test, better reflecting the stress conditions of the sole during actual wearing, preventing the sole from displacement or shaking during the test, resulting in some areas of the sole being unable to contact the simulation device 4, and at the same time being able to test different types of shoes; The cylindrical rod 11 drives the shoe-shaped block 12 to rotate clockwise. When the shoe-shaped block 12 rotates to the lower position, it contacts and rubs with the simulation device 4 to simulate a real walking scene. The shoe-shaped block 12 drives the simulation device 4 to move. The wear resistance of the sole is judged according to the moving position of the simulation device 4. The residence time and movement path of the test plate 41 at different positions of the sole can be clearly observed, thereby improving the testing efficiency of the sole.

[0023] See also Figure 4 and Figure 5 As shown, the moving device 2 includes a moving rod 21 slidably connected to the inside of the cylindrical rod 11, and connecting rods 22 are fixedly connected to both ends of the moving rod 21. One end of the connecting rod 22 extends to the inside of the shoe-shaped block 12, and a top plate 23 is provided at one end of the two connecting rods 22 away from the moving rod 21, and the size of the top plate 23 is smaller than the size of the notch. The moving rod 21 drives the two top plates 23 to move in the same direction through the connecting rod 22. When the moving rod 21 drives the two top plates 23 to move to the left, the top plate 23 is used to support the bottom of the left shoe. At this time, the top plate 23 located on the right does not support the shoe on the right.

[0024] When the two shoe-shaped blocks 12 are rotated to a horizontal state, put the shoe on the left shoe-shaped block 12, see Figure 6-Figure 8As shown, an L-shaped rod 25 is fixedly connected to the moving rod 21, and the L-shaped rod 25 passes through one side of the cylindrical rod 11. A support plate 252 is fixedly connected to the outer wall of the cylindrical rod 11. The interior of the support plate 252 is slidably connected to the upper side of the L-shaped rod 25. The lower side of the L-shaped rod 25 is fixedly connected to a side plate 251. A servo motor 254 is fixedly connected to one side of the support plate 252. The output end of the servo motor 254 is rotatably connected to a rotating rod 255. The other end of the rotating rod 255 is slidably connected to the interior of the side plate 251. When the servo motor 254 is started, The movable rotating rod 255 rotates, and since one end of the rotating rod 255 slides in the side plate 251, the rotating rod 255 rotates to drive the side plate 251 to move, and the side plate 251 drives the L-shaped rod 25 to move back and forth. When the lower end of the L-shaped rod 25 drives the moving rod 21 to move toward the shoe-shaped block 12 on the left, because the two ends of the moving rod 21 are fixedly connected to the connecting rod 22, when the moving rod 21 moves, it drives the two top plates 23 to move toward the shoe-shaped block 12 on the left at the same time. When the connecting rod 22 moves, it drives the two top plates 23 to move in the same direction, so that the top plate 23 moves to the notch of the shoe-shaped block 12 on the left. The top plate 23 is used to support the bottom of the inner part of the left shoe. At this time, the top plate 23 located on the right side does not support the shoe on the right side. The top plate 23 supports the inner bottom of the shoe, and the pressure applied to the outside of the sole during the test can be evenly dispersed to the inside of the sole. In this way, the entire sole can participate in the friction process during the test, and the wear resistance of the sole can be more comprehensively evaluated.

[0025] Since the feet have a certain amount of movement and flexibility when people walk, please refer to Fig. 9 and Fig.10 As shown, one end of the connecting rod 22 is fixedly connected to a fixed plate 24, and a movable block 241 is slidably connected inside the fixed plate 24. The other end of the movable block 241 is fixedly connected to one side of the top plate 23. When the top plate 23 supports the bottom of the shoe, the top plate 23 drives the movable block 241 to move in the fixed plate 24. The top plate 23 can slide while supporting, so that the sole and the simulation device 4 can produce multi-angle changes when in contact and friction. Because in actual walking, the friction angle between the sole and the ground is not fixed, and will change due to factors such as movement of the footsteps and changes in the center of gravity of the body. The sliding of the top plate 23 can allow the sole to simulate this multi-angle friction during the test, thereby more comprehensively examining the wear resistance of the sole under various possible friction conditions.

[0026] See also Figure 7As shown, both sides of the lower end of the L-shaped rod 25 are fixedly connected to the inner wall of the cylindrical rod 11 with tension springs, and the tension spring is sleeved on the moving rod 21. The upper sides of the L-shaped rod 25 and the support plate 252 are fixedly connected with pillars 256, and an extrusion spring is fixedly connected between the two pillars 256. The L-shaped rod 25 extrudes the tension spring when it moves back and forth. At the same time, when the L-shaped rod 25 moves, the upper side of the L-shaped rod 25 slides in the support plate 252 and extrudes the extrusion spring. Under the reaction force of the tension spring and the extrusion spring, the stability of the L-shaped rod 25 is improved, so that the movement effect is better.

[0027] See also Fig. 9 and Fig.10 As shown, the fixing device 3 includes a fixing block 31 fixedly connected to the inside of the shoe-shaped block 12, and the inside of the fixing block 31 is slidably connected to the outside of the connecting rod 22. A through groove 33 is provided inside the connecting rod 22. Two rotating blocks 32 are rotatably connected to the inside of the fixing block 31. The two rotating blocks 32 are symmetrical about the central axis of the connecting rod 22. The ends of the two rotating blocks 32 that are close to each other are arranged in the through groove 33, and the other ends of the two rotating blocks 32 are arranged on one side of the shoe-shaped block 12. When the connecting rod 22 drives the top plate 23 to move toward the left shoe-shaped block 12, the connecting rod 22 drives the top plate 23 to move toward the left shoe-shaped block 12. The movement of the rod 22 drives the two rotating blocks 32 to rotate to both sides, so that the two rotating blocks 32 move away from each other. At this time, the two rotating blocks 32 rotate out of one side of the shoe-shaped block 12. The rotating blocks 32 are used to fix the two sides of the inside of the shoe, ensuring that the shoe and the shoe-shaped block 12 are tightly fitted and stable during the test, better reflecting the stress conditions of the sole during actual wearing, preventing the sole from being displaced or shaking during the test, resulting in certain areas of the sole being unable to contact the simulation device 4, and at the same time, different types of shoes can be tested, thereby improving the practical effect of the device.

[0028] See also Figure 5 and Figure 6 As shown, since the moving rod 21 drives the two top plates 23 to move in the same direction toward the shoe-shaped block 12 on the left side, the top plate 23 on the right side does not support the shoe on the right side. At the same time, the two rotating blocks 32 on the right side rotate inward and move to the inner side of the shoe-shaped block 12 on the right side without fixing the shoe on the right side, making it convenient for the staff to remove the shoe that has been inspected on the right side.

[0029] See also Figure 1-Figure 3 As shown, the support frame 1 is internally rotatably connected to two rotating shafts 48, and one adjacent end of the rotating shaft 48 is fixedly connected to the outer wall of the cylindrical rod 11. A driving motor 47 is fixedly connected to one side of the support frame 1, and the output end of the driving motor 47 is fixedly connected to one end of the rotating shaft 48. The driving motor 47 is started to drive the rotating shaft 48 to rotate, and the rotating shaft 48 drives the cylindrical rod 11 to rotate. The rotation of the cylindrical rod 11 is used to drive the sole to be tested, which is used to simulate a real walking scene.

[0030] See also Figure 2 and Fig.11 As shown, the simulation device 4 includes a mounting seat 46 fixedly connected to the lower side of the support frame 1, a test plate 41 is arranged on the upper side of the mounting seat 46, a slide groove is opened on the upper side of the mounting seat 46, a fixing rod 42 is fixedly connected to the inside of the mounting seat 46, a slider 43 is slidably connected to the outside of the fixing rod 42, the upper end of the slider 43 passes through the slide groove and is fixedly connected to the lower side of the test plate 41, one side of the slider 43 is fixedly connected to the inner wall of the mounting seat 46 with a compression spring, and the compression spring is sleeved on the fixing rod 42, a button 45 is fixedly connected to the inner side of the slide groove away from the slider 43, the cylindrical rod 11 drives the two shoe-shaped blocks 12 to rotate clockwise, and the shoe-shaped blocks 1 When the shoe-shaped block 12 is rotated to the lower position, the shoe-shaped block 12 drives the sole to contact and rub against the test board 41, which is used to simulate a real walking scene. The test board 41 is driven to move by the sole, and the sole drives the test board 41 to move. The test board 41 drives the slider 43 to move on the fixed rod 42 and touch the button 45. When the slider 43 touches the button 45, it means that the wear resistance of the shoe is good. If the slider 43 does not touch the button 45, it means that the wear resistance of the shoe is average. It is convenient to judge the wear resistance of the sole according to the moving position of the test board 41. The residence time and moving path of the test board 41 at different positions of the sole can be clearly observed, thereby improving the testing efficiency of the sole.

[0031] When the rubber sole wear resistance test system and test method of the present invention are used, when the two shoe-shaped blocks 12 are rotated to a horizontal state, the shoe is put on the shoe-shaped block 12 on the left, and the servo motor 254 is started to drive the rotating rod 255 to rotate, so that the rotating rod 255 rotates to drive the moving rod 21 to move toward the shoe-shaped block 12 on the left. When the moving rod 21 moves, it drives the two top plates 23 to move in the same direction, so that the top plate 23 supports the inner bottom of the left shoe. At this time, the top plate 23 on the right side does not support the shoe on the right side. The top plate 23 supports the inner bottom of the shoe, so that the pressure applied to the outside of the sole during the test can be evenly dispersed to the inside of the sole, so that the entire The sole can participate in the friction process during the test, and the wear resistance of the sole can be more comprehensively evaluated. At the same time, when the top plate 23 is supported at the bottom of the shoe, the top plate 23 drives the movable block 241 to move in the fixed plate 24. The top plate 23 can slide while supporting, so that the sole and the simulation device 4 can produce multi-angle changes when in contact and friction. Because in actual walking, the friction angle between the sole and the ground is not fixed, and will change due to factors such as the movement of the footsteps and the change of the body's center of gravity. The sliding of the top plate 23 can simulate this multi-angle friction during the test, so as to more comprehensively examine the wear resistance of the sole under various possible friction conditions. When the moving rod 21 drives the top plate 23 to move toward the shoe-shaped block 12 on the left side, the connecting rod 22 moves to drive the two rotating blocks 32 to rotate one side of the shoe-shaped block 12 to the outside. The rotating blocks 32 are used to fix the two sides of the inside of the shoe, ensuring that the shoe and the shoe-shaped block 12 are tightly fitted and stable during the test, better reflecting the stress conditions of the sole during actual wearing, preventing the sole from being displaced or shaking during the test, resulting in certain areas of the sole being unable to contact the simulation device 4, and at the same time, different types of shoes can be tested, thereby improving the practical effect of the device.

[0032] By starting the driving motor 47 to drive the cylindrical rod 11 to rotate, the cylindrical rod 11 drives the two shoe-shaped blocks 12 to rotate clockwise, and the shoe-shaped blocks 12 drive the sole to contact and rub with the test plate 41 to simulate a real walking scene, and the test plate 41 is driven to move by the sole, and the sole drives the test plate 41 to move, and the test plate 41 drives the slider 43 to move on the fixed rod 42 and touch the button 45. When the slider 43 touches the button 45, it means that the wear resistance of the shoe is good. If the button 45 cannot be touched, it means that the wear resistance of the shoe is average. The wear resistance of the sole is judged according to the moving position of the test plate 41. The residence time and movement path of the test plate 41 at different positions of the sole can be clearly observed, thereby improving the testing efficiency of the sole.

[0033] The second object of the present invention is to provide a method for operating the above-mentioned rubber sole wear resistance testing system to test the wear resistance, comprising the following method steps: S1. First, when the shoe-shaped block 12 is rotated to a horizontal state, a shoe cover is placed on the left shoe-shaped block 12, and the mobile device 2 moves toward the left shoe-shaped block 12 to support the inner bottom of the left shoe. At this time, the mobile device 2 does not support the shoe on the right shoe-shaped block 12. While supporting, the mobile device 2 drives the shoe sole to contact the simulation device 4 to produce multi-angle changes; S2, the moving device 2 then drives the fixing device 3 to rotate while moving, and the fixing device 3 rotates to fix the two sides of the inside of the shoe. During the test, the shoe and the shoe shape block 12 are closely fitted and kept stable, and different types of shoes can be tested at the same time; S3. The cylindrical rod 11 drives the shoe-shaped block 12 to rotate clockwise. The rotation of the shoe-shaped block 12 drives the contact and friction with the simulation device 4 to simulate a real walking scene. During the friction, the shoe-shaped block 12 drives the simulation device 4 to move. The wear resistance of the sole can be judged according to the moving position of the simulation device 4.
