Description

Technical Field

[0001] This invention relates to the field of testing device technology, and more specifically, to a device for testing the abrasion resistance of shoe soles. Background Technology

[0002] Currently, in the shoe manufacturing process, the abrasion resistance of the sole is of particular importance. The abrasion resistance of the sole directly determines the quality and lifespan of the shoe, so many shoe factories are equipped with equipment for testing the abrasion resistance of soles.

[0003] Existing shoe sole abrasion testing equipment often tests the abrasion resistance of the sole by moving the wear parts on the bottom of the shoe. However, during the process of walking, the friction between the sole and the ground is static friction, which makes the test result much less than the actual number of abrasion cycles the sole can withstand.

[0004] Secondly, multiple experiments are needed for shoes of different sizes under the same gravity and shoes of the same size under different gravity. However, many devices are equipped with adjustable foot simulators, which need to be frequently changed when measuring shoes of different sizes, wasting time and resulting in low testing efficiency.

[0005] To address this issue, we propose a shoe sole abrasion resistance testing device. Summary of the Invention

[0006] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide a shoe sole abrasion resistance testing device. This device consists of two sets of testing components suspended on the surfaces of two sets of transmission components. Each set contains multiple testing components, which are evenly distributed on the surface of the transmission components. By activating a small motor, both sets of testing components can be driven to rotate simultaneously, enabling synchronous testing of the sole abrasion resistance of multiple shoes under test. This allows for the acquisition of multiple sets of data, improving data accuracy and increasing the efficiency of sole abrasion resistance testing, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a shoe sole abrasion resistance testing device, comprising: a support mechanism in which two sets of transmission components are installed through; a testing mechanism comprising two sets of testing components spaced 180º apart, both sets of testing components being suspended on the surfaces of the two sets of transmission components, each set containing multiple testing components, the multiple testing components being distributed at equal intervals on the surface of the transmission components, one set of testing components having a shoe of the same size fitted at the bottom end but different lengths of different testing components, and the other set of testing components having a shoe of a different size fitted at the bottom end and multiple testing components having the same length;

[0008] The detection mechanism also includes the bottom end of the inner wall of the support mechanism suspended inside the support structure, located directly below the two sets of transmission components. The two sets of transmission components drive the detection component to move circumferentially and then abut against the self-blocking component, causing the self-blocking component to displace. The friction generated between the self-blocking component and the detection component is used to wear down the sole of the shoe.

[0009] In a preferred embodiment, the support mechanism includes two sets of L-shaped suspension plate assemblies for supporting the transmission assembly and two sets of horizontal support plates for suspending the self-blocking component. The two sets of L-shaped suspension plate assemblies are welded to the ends of the two sets of horizontal support plates, and the two sets of L-shaped suspension plate assemblies are arranged axially symmetrically about the transverse center line of the self-blocking component. Each set of L-shaped suspension plate assemblies includes two L-shaped suspension plates located on the same horizontal line, the horizontal line of which is parallel to the transverse horizontal line of the self-blocking component. The two sets of L-shaped suspension plate assemblies are respectively welded to the upper surface of the two sets of horizontal support plates.

[0010] In a preferred embodiment, the two sets of self-blocking components include two sets of suspension rods detachably installed inside the horizontal support plate. The suspension rods are at 90° to the two sets of horizontal support plates, and the distances of the two sets of suspension rods from the ends of the horizontal support plates are equal. Two sets of rectangular pedals are slidably installed on the surfaces of the two sets of suspension rods, and the ends of the two sets of rectangular pedals are abutted against the two sets of horizontal support plates.

[0011] The rectangular foot pedal has multiple sets of conveyor belts of equal width fixed to its surface. Each set of conveyor belts has two silicone barrier strips attached to both sides. The multiple sets of conveyor belts are fixed in position by the silicone barrier strips. The two sets of silicone barrier strips located on the side are flush with the side of the rectangular foot pedal, and the height of the silicone barrier strips is greater than the thickness of the conveyor belt.

[0012] In a preferred embodiment, the bottom end of the horizontal support plate is glued with a plurality of adsorption plates. The plurality of adsorption plates are used to raise the self-blocking component to prevent the silicone barrier strip from contacting the plane and to fix the position of the two sets of horizontal support plates. The two sets of transmission components are used to limit the distance between the two sets of horizontal support plates.

[0013] The support mechanism has three sets of output rods rotatably mounted inside. Each of the three sets of output rods passes through one end of the L-shaped suspension plate assembly and is sleeved on one of the three sets of ring gears. Each set of ring gears contains two meshing ring gears. One ring gear is welded to the surface of the output rod, and the other ring gear is fixed to the surface of the transmission assembly. Each ring gear is in contact with the inner wall of the horizontal support plate.

[0014] In a preferred embodiment, a small motor is fixed to one end of the ring gear set through the other end of the L-shaped suspension plate set. The small motor is fixed to the outer wall of the horizontal support plate. A set of synchronous belts is sleeved on one end of the other two sets of ring gear sets through the L-shaped suspension plate set. Two sets of positioning rings that restrict the change of position of the synchronous belts are attached to the surface of the synchronous belts. The two sets of synchronous belts are fixed to the ends of the two sets of ring gear sets.

[0015] In a preferred embodiment, the transmission assembly includes a lug-type transmission roller that passes through two sets of L-shaped suspension plate assemblies. Two sets of round-headed Phillips head self-tapping screws are threaded onto both ends of the lug-type transmission roller, and the two sets of round-headed Phillips head self-tapping screws abut against the outer wall of the L-shaped suspension plate assembly.

[0016] The lug-type drive roller includes a set of circular rods. Two sets of symmetrical semi-circular arc plates are welded to the surface of the middle part of the rods. The length of the semi-circular arc plates is shorter than the length of the circular rods. Multiple sets of positioning grooves are formed on the surface of the lug-type drive roller. Each set of positioning grooves has two grooves. The distance between the two positioning grooves is the superimposed thickness of the lug-type drive roller and the two sets of round-headed Phillips head self-tapping screws.

[0017] In a preferred embodiment, the detection component includes two sets of left and right fixing plates that engage with the surface of the lug-driven roller. A rectangular frame is inserted between the two sets of left and right fixing plates. The inner diameter of the rectangular frame is the outer diameter of the circular rod. The two sets of left and right fixing plates have the same structure and are longitudinally inserted into the surface of the lug-driven roller in two opposite directions. Both sets of left and right fixing plates are in close contact with the surface of the lug-driven roller. Fasteners pass through the rectangular frame and the two sets of left and right fixing plates, and the positions are relatively fixed by the fasteners. Multiple mounting holes for fastener screws are provided on the surfaces of the rectangular frame and the left and right fixing plates. The fasteners are matching bolts and nuts.

[0018] In a preferred embodiment, the bottom end of the mounting hole is provided with two sets of parallel square connecting plates. One set of square connecting plates is fixed to the mounting hole, and the top end of the other set of square connecting plates is welded with a foot simulation block. Multiple sets of telescopic component square slots are fixed between the two sets of parallel square connecting plates. The surface of the upper set of square connecting plates has two sets of slots, and the two sets of slots are symmetrically distributed about the vertical center line of the rectangular frame.

[0019] The telescopic component square slot shown includes a telescopic rod and a spring fixed to the surface of two sets of square connecting plates, wherein the spring is sleeved around the telescopic rod at the corresponding position.

[0020] In a preferred embodiment, the surface of the self-blocking component is rotatably mounted with a plurality of trajectory positioning components, two of which correspond to a detection component. Each trajectory positioning component includes an annular collar, and a plurality of built-in balls are distributed circumferentially on the inner wall of the annular collar. The plurality of built-in balls are located on the same circumference, and the size of the inner wall formed by the plurality of built-in balls is consistent with the outer diameter of the circular rod.

[0021] A set of telescopic elastic rods is welded to the top of the annular collar, and the bottom shape of the telescopic elastic rods is consistent with the groove shape of the square slot.

[0022] The technical effects and advantages of this invention are as follows:

[0023] 1. In this invention, two sets of detection components are suspended on the surfaces of two sets of transmission components. Each set of detection components consists of multiple components, which are distributed at equal intervals on the surface of the transmission components. By turning on a small motor, the two sets of detection components can be driven to rotate simultaneously, thereby enabling the synchronous detection of the abrasion resistance of the soles of multiple shoes to be tested. This allows for the acquisition of multiple sets of data, improving the accuracy of the data and increasing the efficiency of sole abrasion resistance testing.

[0024] 2. In this invention, one set of detection components is used to wear shoes of the same size and the other set of detection components is used to wear shoes of different sizes. By changing the position of the ear-driven roller inside each rectangular frame, multiple detection methods are achieved, such as the same size with the same weight, the same size with different weight, and different sizes with the same weight, to detect the different differences in the abrasion resistance of the sole when the size and weight are different.

[0025] 3. In this invention, the transmission component drives the rotation to achieve the contact phenomenon between the shoe under test and the surface of the self-resistance component. The resistance between the shoe under test and the self-resistance component enables the conveyor belt to slide on the rectangular foot pedal surface, achieving synchronous displacement between the shoe under test and the conveyor belt. This causes static friction between the sole of the shoe and the surface of the conveyor belt, simulating the wear pattern of the sole of a pedestrian's footsteps, thereby improving the accuracy of the test results.

[0026] 4. In this invention, silicone barrier strips are used to separate multiple conveyor belts, thereby causing each conveyor belt 64 to form an independent entity, preventing different shoes from hindering each other during the testing process and reducing the testing efficiency of shoe sole abrasion resistance.

[0039] 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.

[0040] Refer to the instruction manual appendix Figure 1-11 An embodiment of the present invention provides a shoe sole abrasion resistance testing device, comprising: a support mechanism in which two sets of transmission components 4 are installed through, the two sets of transmission components 4 being used to position the lateral length of the entire shoe sole abrasion resistance testing device; and a testing mechanism comprising two sets of testing components 9 arranged at 180º to each other, both sets of testing components 9 being suspended on the surfaces of the two sets of transmission components 4, each set of testing components 9 comprising multiple testing components 9, the multiple testing components 9 being distributed at equal intervals on the surface of the transmission components 4; one set of testing components 9 having a shoe of the same size fitted at the bottom end, but the lengths of the different testing components 9 being different; and the other set of testing components 9 having a shoe of a different size fitted at the bottom end, and the lengths of the multiple testing components 9 being the same.

[0041] During operation, when different sizes of shoes are fitted together, the bottom of each detection component 9 is not the same size, which simulates the human foot and prevents the pressure value on the sole of the shoe from being inconsistent with the pressure value on the shoe body when a pedestrian stands on it when the shoe is in contact with the surface of the self-blocking component 6.

[0042] As an embodiment of the present invention, the support mechanism includes two sets of L-shaped suspension plate groups 2 for supporting the transmission assembly 4 and two sets of horizontal support plates 1 for suspending the self-blocking component 6. The two sets of L-shaped suspension plate groups 2 are welded to the ends of the two sets of horizontal support plates 1, and the two sets of L-shaped suspension plate groups 2 are arranged symmetrically about the transverse center line of the self-blocking component 6. Each set of L-shaped suspension plate groups 2 includes two L-shaped suspension plates located on the same horizontal line, whose horizontal line is parallel to the transverse horizontal line of the self-blocking component 6. The two L-shaped suspension plate groups 2 are respectively welded to the upper surface of the two sets of horizontal support plates 1.

[0043] As an embodiment of the present invention, the transmission assembly 4 includes a lug-type transmission roller 41 that passes through two sets of L-shaped suspension plate assemblies 2. Two sets of round-headed cross self-tapping screws 42 are screwed into the two ends of the lug-type transmission roller 41 by threads. The two sets of round-headed cross self-tapping screws 42 abut against the outer wall of the L-shaped suspension plate assemblies 2.

[0044] The lengths of the two sets of transmission components 4 are fixed, that is, the distance between the two sets of horizontal support plates 1 is fixed, thus fixing the overall structure of the entire sole abrasion resistance testing device.

[0045] The lug-type drive roller 41 includes a set of circular rods. Two sets of symmetrical semi-circular arc plates are welded to the surface of the middle of the rods. The length of the semi-circular arc plates is shorter than the length of the circular rods. Multiple sets of positioning grooves 43 are opened on the surface of the lug-type drive roller 41. Each set of positioning grooves 43 has two grooves. The distance between the two positioning grooves 43 is the superimposed thickness of the lug-type drive roller 41 and the two sets of round-headed cross self-tapping screws 42.

[0046] In one embodiment of the present invention, the detection component 9 includes two sets of left and right fixing plates 92 that engage with the surface of the lug-driven roller 41. A rectangular frame 91 is inserted between the two sets of left and right fixing plates 92. The inner diameter of the rectangular frame 91 is the outer diameter of the circular rod. The two sets of left and right fixing plates 92 have the same structure and are longitudinally inserted into the surface of the lug-driven roller 41 in two opposite directions. Both sets of left and right fixing plates 92 are in close contact with the surface of the lug-driven roller 41. Fasteners 93 pass through the rectangular frame 91 and the two sets of left and right fixing plates 92, and the relative positions are fixed by the fasteners 93. Multiple mounting holes 94 for the fasteners 93 to be screwed are opened on the surface of the rectangular frame 91 and the left and right fixing plates 92. The fasteners 93 are matching bolts and nuts.

[0047] During operation, the ear-driven roller 41 can move up and down inside the rectangular frame 91 but cannot be positioned. With the clamping of two sets of left and right fixed plates 92 and the cooperation of fasteners 93, the position of the detection component 9 and the surface of the transmission component 4 is fixed. When the up and down position of the ear-driven roller 41 inside the rectangular frame 91 is changed, the diameters of the two sets of circles formed by the detection component 9 moving circumferentially around the horizontal center line of the ear-driven roller 41 are different.

[0048] As an embodiment of the present invention, the bottom end of the mounting hole 94 is provided with two sets of parallel square connecting plates 95. One set of square connecting plates 95 is fixed to the mounting hole 94, and the top end of the other set of square connecting plates 95 is welded with a foot simulation block 97. Multiple sets of telescopic component square slots 96 are fixed between the two sets of parallel square connecting plates 95. Two sets of 98 are opened on the surface of the set of square connecting plates 95 located at the upper end. The two sets of 98 are symmetrically distributed about the vertical center line of the rectangular frame 91.

[0049] The telescopic component square slot 96 shown includes a telescopic rod and a spring fixed to the surface of two sets of square connecting plates 95, wherein the spring is sleeved around the telescopic rod at the corresponding position.

[0050] When working, if it is necessary to test the wear of the soles of shoes of the same size but different weights, it is only necessary to change the position of the ear-driven roller 41 within the rectangular frame 91. However, in this process, it is necessary to use a pressure gauge to test the different pressure values ​​corresponding to different positions in advance.

[0051] If it is necessary to test the wear of the sole corresponding to different sizes of the same weight, wear the different corresponding sizes on the surface of the foot simulation block 97, and then keep the ear-driven roller 41 in the same position in each rectangular frame 91.

[0052] The detection mechanism also includes the bottom of the inner wall of the support mechanism suspended inside the support structure, located directly below the two sets of transmission components 4. The two sets of transmission components 4 drive the detection component 9 to move circumferentially and then abut against the self-blocking component 6, causing the self-blocking component 6 to move. The friction generated between the self-blocking component 6 and the detection component 9 is used to wear down the sole of the shoe.

[0053] This device drives the detection component 9 to move circumferentially, which in turn abuts against the self-resisting component 6, causing the self-resisting component 6 to displace. This friction between the detection component 9 and the self-resisting component 6 is used to rub the sole of the shoe, simulating the relative motion between the sole and the ground when a pedestrian walks. This makes the sole abrasion resistance test more accurate and closer to the precise value. Secondly, two sets of detection components 9 are set at 180º to each other. Both sets of detection components 9 are suspended on the surface of two sets of transmission components 4. Each set contains multiple detection components 9, which are evenly distributed on the surface of the transmission components 4. The bottom of one set of detection components 9 is fitted with a shoe of the same size, but the lengths of the different detection components 9 are different. The bottom of the other set of detection components 9 is fitted with a shoe of a different size, and the lengths of the multiple detection components 9 are all the same. This allows for simultaneous testing of the differences in sole wear caused by different gravity and different sizes, increasing the number of tests, reducing testing time, and improving testing efficiency.

[0054] As an embodiment of the present invention, the two sets of self-blocking components 6 include two sets of suspension rods 61 detachably installed inside the horizontal support plate 1. The suspension rods 61 are at a 90° angle to the two sets of horizontal support plates 1, and the distances of the two sets of suspension rods 61 from the ends of the horizontal support plates 1 are equal. Two sets of rectangular pedals 62 are slidably installed on the surfaces of the two sets of suspension rods 61, and the ends of the two sets of rectangular pedals 62 are abutted against the two sets of horizontal support plates 1.

[0055] Multiple sets of conveyor belts 64 of equal width are fixed to the surface of the rectangular foot pedal 62. Two silicone barrier strips 63 are attached to both sides of each set of conveyor belts 64. The multiple sets of conveyor belts 64 are fixed in position by the silicone barrier strips 63. The two sets of silicone barrier strips 63 located on the side are flush with the side of the rectangular foot pedal 62. The height of the silicone barrier strips 63 is greater than the thickness of the conveyor belts 64.

[0056] During operation, the silicone barrier strip 63 is used to separate multiple conveyor belts 64, thereby causing each conveyor belt 64 to form an independent entity. Different sizes and weights of shoe soles are placed on the conveyor belts and they obstruct each other during the testing process, thereby improving the testing efficiency of shoe sole abrasion resistance.

[0057] As an embodiment of the present invention, a plurality of adsorption plates 5 are glued to the bottom end of the horizontal support plate 1. The plurality of adsorption plates 5 are used to raise the self-blocking component 6 to avoid the silicone barrier strip 63 from contacting the plane and to fix the position of the two sets of horizontal support plates 1. The two sets of transmission components 4 are used to limit the distance between the two sets of horizontal support plates 1.

[0058] The support mechanism has three sets of output rods 3 installed inside in a rotating manner. The three sets of output rods 3 pass through one end of the L-shaped suspension plate group 2 and are all sleeved on three sets of ring gear groups 8. Each set of ring gear groups 8 contains two meshing ring gears. One ring gear is welded to the surface of the output rod 3, and the other ring gear is fixed to the surface of the transmission component 4. Each ring gear is in contact with the inner wall of the horizontal support plate 1.

[0059] As an embodiment of the present invention, a set of ring gears 8 passes through the other end of the L-shaped suspension plate group 2 and is fixed with a small motor 12. The small motor 12 is fixed to the outer wall of the horizontal support plate 1. The other two sets of ring gears 8 pass through one end of the L-shaped suspension plate group 2 and are fitted with a set of synchronous belts 10. Two sets of positioning rings 11 that restrict the change of position of the synchronous belts 10 are attached to the surface of the synchronous belts 10. The two sets of synchronous belts 10 are fixed to the ends of the two sets of ring gears 8.

[0060] During operation, the small motor 12, model Y80m1-2, serves as the drive source. The output rod 3 is fixed to the end of the output shaft of the small motor 12. The output rod 3 causes the transmission component 4 to rotate through the ring gear set 8. The synchronous output rod 3 causes another set of transmission components 4 to rotate synchronously through the synchronous belt 10 and the ring gear set 8. The directions of rotation are opposite. In order to prevent the two sets of detection components 9 from being obstructed during rotation, the two sets of detection components 9 are set at 180º to each other.

[0061] This device achieves simultaneous abrasion resistance testing of multiple shoe soles using only one set of drive sources. It features a simple architecture, is easy to operate and portable, saves energy, and ensures accurate data.

[0062] As an embodiment of the present invention, the transmission assembly 4 includes a lug-type transmission roller 41 that passes through two sets of L-shaped suspension plate assemblies 2. Two sets of round-headed cross self-tapping screws 42 are screwed into the two ends of the lug-type transmission roller 41 by threads. The two sets of round-headed cross self-tapping screws 42 abut against the outer wall of the L-shaped suspension plate assemblies 2.

[0063] The lug-type drive roller 41 includes a set of circular rods. Two sets of symmetrical semi-circular arc plates are welded to the surface of the middle of the rods. The length of the semi-circular arc plates is shorter than the length of the circular rods. Multiple sets of positioning grooves 43 are opened on the surface of the lug-type drive roller 41. Each set of positioning grooves 43 has two grooves. The distance between the two positioning grooves 43 is the superimposed thickness of the lug-type drive roller 41 and the two sets of round-headed cross self-tapping screws 42.

[0064] As an embodiment of the present invention, a plurality of trajectory positioning components 7 are rotatably mounted on the surface of the self-blocking component 6. Two trajectory positioning components 7 correspond to one detection component 9. The trajectory positioning component 7 includes an annular collar 71. A plurality of built-in balls 73 are distributed circumferentially on the inner wall of the annular collar 71. The plurality of built-in balls 73 are located on the same circumference, and the size of the inner wall formed by the plurality of built-in balls 73 is consistent with the outer diameter of the circular rod.

[0065] A set of telescopic elastic rods 72 are welded to the top of the annular collar 71. The bottom shape of the telescopic elastic rods 72 is consistent with the groove shape of the square slot 98.

[0066] During operation, the position of the trajectory positioning component 7 is restricted by the positioning groove 43, and the position of the detection component 9 is fixed by the clamping action of the two sets of trajectory positioning components 7 located on both sides of the detection component 9.

[0067] Working principle: Two sets of horizontal support plates 1 are placed in parallel, and self-blocking components 6 are inserted inside the bottom end of the horizontal support plates 1. Two sets of transmission components 4 are fixed inside the two sets of L-shaped suspension plate groups 2 to determine the width of the sole abrasion resistance testing device. The position of the sole abrasion resistance testing device is determined by vacuum adsorbing multiple adsorption plates 5 at the bottom end of the horizontal support plates 1 onto the plane.

[0068] Shoes of different sizes are worn in sequence on the surface of the foot simulation block 97. The switch of the small motor 12 is turned on, which causes the two sets of transmission components 4 to rotate, and in turn causes the two sets of detection components 9 to rotate.

[0069] To ensure data accuracy, the abrasion resistance of the soles of multiple pairs of shoes of the same size and weight is tested. The ear-driven roller 41 is kept in the same position inside each rectangular frame 91. Under natural gravity, the top of each rectangular frame 91 is flush. The motor is turned on, driving each set of testing components 9 to rotate synchronously. The sole of the shoe under test rubs against the self-resisting component 6. The friction causes the conveyor belt 64 to slide on the surface of the rectangular foot pedal 62. The sole of the shoe under test rubs against the conveyor belt 64, thus achieving wear.

[0070] To ensure data accuracy, the abrasion resistance of the soles of multiple pairs of shoes of the same size but under different weights is tested. The position of the drive roller 41 with ear loops is changed to be the same inside each rectangular frame 91. Under natural gravity, the top of each rectangular frame 91 is at a different height. The lower the height of the rectangular frame 91, the greater the pressure the shoe bears. This simulates the wear and tear of shoes worn by people of the same size under different weights. The motor is turned on to drive each set of testing components 9 to rotate synchronously. The sole of the shoe under test rubs against the self-resisting component 6. The friction causes the conveyor belt 64 to slide on the surface of the rectangular foot pedal 62. The sole of the shoe under test rubs against the conveyor belt 64, thus achieving wear.

[0071] To ensure data accuracy, the abrasion resistance of the soles of multiple pairs of shoes with different sizes and the same weight is tested. The inner position of the drive roller 41 with the ear is the same as that of each rectangular frame 91. Under natural gravity, the top of each rectangular frame 91 is the same. At this time, the size of the corresponding foot simulation block 97 is different. The shoes of different sizes are put on the corresponding foot simulation block 97. The motor is turned on to drive each set of detection components 9 to rotate synchronously. The sole of the shoe under test rubs against the self-resistance component 6. The friction causes the conveyor belt 64 to slide on the surface of the rectangular foot pedal 62. The sole of the shoe under test rubs against the conveyor belt 64 and thus wears out.

[0072] Two sets of detection components 9 move simultaneously and independently of each other, improving the accuracy of wear resistance results and increasing efficiency.
