Description

Technical Field

[0001] The invention relates to the technical field of quality detection of TPU decorative pieces for sports shoes, and in particular to a quality detection device and method for TPU decorative pieces for sports shoes. Background Art

[0002] Sports shoe TPU (thermoplastic polyurethane) trim is a common footwear decoration and functional component, usually used in the upper, side, heel and other parts to provide beauty, support and durability. TPU material has high strength, good flexibility, wear resistance and impact resistance, and is widely used in the design of sports shoes. After the production and processing of TPU trim, a series of quality inspections are required to ensure that it can meet the performance requirements and avoid quality problems such as severe wear, cracks and breakage during use; among them, wear resistance and bending life are two key inspection items, which determine the durability of TPU trim in actual wear. Due to the diverse shapes of TPU trims, which are usually irregular shapes, standardized rectangular samples are usually selected for testing when conducting wear resistance tests and bending tests to ensure the repeatability of the test and the comparability of the data.

[0003] The traditional method is usually to test wear resistance first and then test bending life. However, in actual use, the TPU trim of sports shoes will be subjected to friction and bending at the same time. Testing wear resistance and bending separately cannot simulate actual usage conditions and has great limitations, resulting in low practical significance of the test results.

[0004] Moreover, traditional wear tests (such as Taber wear tests) usually use fixed weights (such as 500g or 1000g) to apply pressure. Due to the limitation of fixed friction force, it is difficult to simulate the stress conditions in different usage scenarios, such as light walking or strenuous exercise. At the same time, existing flexural test equipment (such as Ross Flex, MIT flexural test machine) usually uses a fixed bending angle of 90° or 180°, which cannot flexibly simulate the actual bending conditions of sports shoes in different running and jumping postures, further affecting the authenticity of the test results. Summary of the invention

[0005] The present invention provides a device and method for detecting the quality of TPU trims for sports shoes, which solve the technical problems that traditional wear resistance and bendability tests are usually conducted separately, making it difficult to simulate the situation that the TPU trims for sports shoes are subjected to friction and bending simultaneously in actual use, and the detection conditions are single, which limits the practical significance of the test results; the force differences in different usage scenarios cannot be reproduced; fixed angles are mostly used, and the bending conditions in different sports states such as running and jumping cannot be flexibly simulated, resulting in the test results being unable to accurately reflect the actual usage performance.

A shifting post is also fixedly connected to the side of the No. 2 strip frame away from the No. 2 spring telescopic rod.

[0009] The two levers have the respective pivot points, the first pivot point being an upper pivot point, the second pivot points being an upper pivot point, the lower pivot points being an upper pivot point, and the lower pivot points being a lower pivot point.

[0010] In a possible implementation, an annular guide groove is provided on the outside of the toothed disc, and a limiting guide bar for cooperating with the annular guide groove is fixedly connected to the lower portion of the rack.

[0011] In one possible implementation, the clamping mechanism located on the No. 1 mounting seat includes sliding columns that are symmetrically fixed to the front and rear end faces of the No. 1 mounting seat, a mounting plate is slidably connected to the outside of the left and right two sliding columns, a top spring is fixedly connected between the mounting plate and the No. 1 mounting seat, and a chuck is fixedly connected to the lower end face of the mounting plate.

[0012] In a possible implementation, the friction part includes a mounting frame fixedly connected to the upper end surface of the detection platform, and a plurality of friction plates with different surface roughness are equidistantly and detachably connected to the bottom of the mounting frame cavity.

[0013] In a possible implementation, a plurality of positioning holes are equidistantly formed at the bottom of the mounting frame cavity, and a positioning column that matches the positioning hole is fixedly connected to the lower end surface of the friction plate.

[0014] In a possible implementation, the combined mechanism includes two electric sliders symmetrically slidably connected to the upper end surface of the detection platform, a portal frame is fixedly connected between the two electric sliders, an electric telescopic frame is installed on the lower end surface of the transverse section of the portal frame, and the front end surfaces of the No. 1 mounting seat and the No. 2 mounting seat are fixedly connected to extension rods, and the front end of the extension rod is hinged to the electric telescopic frame.

[0015] A method for detecting the quality of TPU trims for sports shoes is completed by using a device for detecting the quality of TPU trims for sports shoes, and comprises the following steps: S1: selecting a TPU trim sample for sports shoes of a universal sample size, and making the sample thickness consistent with the actual product, and then clamping the sample using a clamping mechanism.

[0018] S4: Finally, use a microscope or a magnifying glass to observe whether there are cracks, breaks or layer peeling on the surface of the sports shoe TPU trim samples after two different tests.

[0019] It can be seen from the above technical scheme that the present invention has the following advantages: In the present invention, the moving parts of the dynamic wear measuring mechanism and the adjustable bending measuring mechanism are overlapped through a combined mechanism, and the friction and bending tests are performed on the TPU trim of the sports shoes at the same time, which truly simulates the working conditions of the TPU trim of the sports shoes in actual use, and reflects the performance of the material when the shoes are subjected to the combined effects of friction and bending when walking, running or jumping, thereby ensuring that the test results are consistent with reality.

The flexibility of the testing conditions makes the test more detailed, which can reflect the durability differences of the TPU trim of sports shoes in different usage scenarios, facilitate comparison, and improve the accuracy of the test results.

[0021] In the present invention, the pressure applied by the I-shaped pressure plate on the TPU trim of the sports shoe is dynamically adjusted by combining the driving component and the dynamic wear measuring mechanism, thereby realizing dynamic adjustment of the friction force, overcoming the limitation of the pressure applied by fixed weights in the traditional wear resistance testing method, ensuring that the test can more comprehensively cover different usage conditions, thereby providing test data with practical significance, and improving the reliability of the test results.

[0022] In the present invention, by adjusting the pins in the adjustable bending measurement mechanism in the sockets at different positions of the toothed disc, the curvature of the TPU trim of the sports shoe during the bending test can be adjusted, thereby simulating different conditions of the sports shoe from slight bending to severe bending in different gaits, thereby further improving the authenticity and accuracy of the test results.

[0033] See also Figure 1 , Figure 2 and Figure 4 The present invention provides a technical solution: a sports shoe TPU decorative piece quality inspection device, comprising a detection platform 1, the upper end surface of the detection platform 1 is fixedly connected to a strip slide box 2 with a front opening through a fixing rod, a plurality of connecting telescopic columns 3 are slidably connected in the strip slide box 2, and the front ends of the connecting telescopic columns 3 are respectively fixedly connected to a staggered No. 1 mounting seat 4 and a No. 2 mounting seat 5, respectively, and the No. 1 mounting seat 4 and the No. 2 mounting seat 5 are respectively provided with a clamping mechanism 6 for clamping a sports shoe TPU decorative piece sample, and a friction portion is provided on the detection platform 1. 7. A dynamic wear measuring mechanism 8 is arranged on the No. 1 mounting seat 4, and the pressures applied to the samples by the multiple dynamic wear measuring mechanisms 8 are different. An adjustable bending measuring mechanism 9 is arranged on the No. 2 mounting seat 5, and the curvatures of the bending of the samples by the multiple adjustable bending measuring mechanisms 9 are different. A combined mechanism 10 for combining the dynamic wear measuring mechanism 8 and the adjustable bending measuring mechanism 9 for operation together is arranged between the test platform 1, the No. 1 mounting seat 4 and the No. 2 mounting seat 5, so as to simultaneously perform wear resistance and bending performance tests on the sports shoe TPU trim samples.

[0034] See also Figure 1 , Figure 4 and Figure 6 In this embodiment, the clamping mechanism 6 located on the No. 1 mounting seat 4 includes a sliding column 61 that is symmetrically fixedly connected to the front and rear side end faces of the No. 1 mounting seat 4, and a mounting plate 62 is slidably connected to the outside of the left and right sliding columns 61. A top spring is fixedly connected between the mounting plate 62 and the No. 1 mounting seat 4, and a clamp 63 is fixedly connected to the lower end face of the mounting plate 62. The clamping mechanism 6 located on the No. 2 mounting seat 5 has the same installation orientation and distribution as the clamping mechanism 6 installed on the No. 1 mounting seat 4.

The bottom of the mounting frame 71 cavity is equidistantly provided with a plurality of positioning holes, and the lower end face of the friction plate 72 is fixedly connected to a positioning column that matches the positioning holes.

[0035] Before testing the sports shoe TPU trim samples, the friction plates 72 with different roughness are stacked and laid in the installation frame 71 in sequence, and the friction plates 72 are limited by inserting positioning columns into the positioning holes to prevent the friction plates 72 from moving during subsequent testing. Then, the rectangular sports shoe TPU trim samples are placed in the corresponding front and rear clamps 63 and clamped.

[0036] See also Figure 3 , Figure 4 and Figure 6 In this embodiment, the dynamic wear measuring mechanism 8 includes a No. 1 spring telescopic rod 81 that is slidably connected to the No. 1 mounting seat 4, a No. 1 strip frame 82 that is slidably connected to the No. 1 spring telescopic rod 81 and is perpendicular to the axis of the No. 1 spring telescopic rod 81, and an I-shaped pressing plate 83 that is fixedly connected to the lower end of the No. 1 spring telescopic rod 81. A shifting post 84 is fixedly connected to the side of the No. 1 strip frame 82 away from the No. 1 spring telescopic rod 81.

[0037] See also Figure 3 , Figure 4 and Figure 5 The adjustable bending mechanism 9 includes two lugs 91 respectively fixedly connected to the left and right sides of the No. 2 mounting seat 5, a No. 2 spring telescopic rod 92 respectively penetrating and slidingly connected to the two lugs 91, a No. 2 strip frame 93 penetrating and slidingly connected to the No. 2 spring telescopic rod 92 and perpendicular to the axis of the No. 2 spring telescopic rod 92, and an I-shaped clamp 94 fixedly connected to the lower end of the No. 2 spring telescopic rod 92. The side of the No. 2 strip frame 93 away from the No. 2 spring telescopic rod 92 is also fixedly connected to a shifting post 84.

[0038] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7The upper end surface of the detection platform 1 is symmetrically fixedly connected to two slides 11 with upper openings through pillars. A driving component for synchronously cooperating with the lever 84 to drive the No. 1 spring telescopic rod 81 and the No. 2 spring telescopic rod 92 to reciprocate up and down is commonly provided between the two slides 11, the No. 1 mounting seat 4 and the No. 2 mounting seat 5. The driving component includes a drive member 12 arranged between the No. 1 mounting seat 4 and the two slides 11. The drive member 12 includes a bearing sleeve 121 fixedly connected to the upper end surface of the No. 1 mounting seat 4 through a fixing bar, a toothed disc 122 rotatably connected to the bearing sleeve 121, and a plurality of racks 123 that are slidably connected between the two slides 11 and correspond to the number of toothed discs 122. , and the rack 123 is located above the corresponding toothed disc 122 and meshes with the toothed disc 122, a strip-shaped through groove 124 is opened on the toothed disc 122 along its own radial direction, and a number of jacks 125 for cooperating with the lever 84 are opened at equal intervals in the strip-shaped through groove 124, and an elastic sleeve is fixedly connected to the outside of the lever 84, and a drive component 2 with the same structure as the drive component 1 12 is jointly arranged between the second mounting seat 5 and the two slide seats 11, and an annular guide groove 13 is opened on the outside of the toothed disc 122, and a limiting guide bar 14 for cooperating with the annular guide groove 13 is fixedly connected to the lower part of the rack 123, and the annular guide groove 13 and the limiting guide bar 14 are engaged with each other to enable the toothed disc 122 to drive the rack 123 to move synchronously when it moves horizontally.

[0039] First, the combined mechanism 10 is controlled to operate to drive the No. 1 mounting seat 4 and the No. 2 mounting seat 5 to reciprocate back and forth, and the No. 1 mounting seat 4 and the No. 2 mounting seat 5 then drive the bearing sleeve 121 installed on themselves to move synchronously, and the bearing sleeve 121 then drives the toothed disc 122 to reciprocate back and forth. During the reciprocating movement of the toothed disc 122, it automatically rotates through the interaction with the rack 123. The rotation of the toothed disc 122 drives the socket 125 to change circumferentially, and the socket 125 drives the No. 1 bar frame 82 and the No. 2 bar frame 93 to move up and down and horizontally through the lever 84. During the up and down and horizontal movement of the No. 1 bar frame 82, the No. 1 spring telescopic rod 81 is driven to reciprocate up and down. During the downward movement of the No. 1 spring telescopic rod 81, the I-shaped pressing plate 83 is driven to move down and touch the sports shoe TPU decorative plate sample, and continue to press down and contract the sports shoe TPU decorative plate sample. The PU trim sample is pressurized, thereby increasing the friction between the sports shoe TPU trim sample and the friction plate 72. When the No. 1 spring telescopic rod 81 is driven to move upward, the No. 1 spring telescopic rod 81 will reset and extend, gradually causing the I-shaped pressure plate 83 to weaken the friction force on the friction plate 72, thereby dynamically adjusting the friction force of the sports shoe TPU trim sample during friction testing, so that the test process is more in line with the actual use process; in addition, the lever 84 can be pushed and pulled along the path direction of the strip through groove 124 to deform the elastic sleeve on its outside, thereby causing the lever 84 to enter the strip through groove 124, and finally enter into another plug hole 125, thereby adjusting the lever 84 to move to the highest and lowest horizontal height positions, thereby indirectly adjusting the pressure applied by the I-shaped pressure plate 83 to the sports shoe TPU trim sample.

[0040] When the lever 84 drives the No. 2 bar frame 93 to move up and down and horizontally, the No. 2 bar frame 93 will drive the No. 2 spring telescopic rod 92 to move up and down, and the No. 2 spring telescopic rod 92 will then drive the I-shaped clamp 94 to move up (while the sports shoe TPU decorative piece sample is clamped by the clamp 63 located on the No. 2 mounting seat 5, the I-shaped clamp 94 is also clamped on the outside of the sports shoe TPU decorative piece sample, and the two I-shaped clamps 94 cooperate with each other to be clamped on the left and right parts of the sports shoe TPU decorative piece sample respectively). When the I-shaped clamp 94 moves up, the middle part of the sports shoe TPU decorative piece sample is pulled upward to bend the sports shoe TPU decorative piece sample. During the bending process of the sports shoe TPU decorative piece sample, its front and rear parts will pull the clamp 63 to move the sports shoe TPU decorative piece sample upward. The heads 63 move closer to each other, and the clamp 63 then drives the mounting plate 62 to slide outside the slide rod, so that the top spring is compressed. When the No. 2 spring telescopic rod 92 drives the I-shaped clamp 94 to move downward, the top spring drives the front and rear mounting plates 62 to move away from each other, and the mounting plate 62 then drives the clamp 63 to move away from each other and reset. The clamp 63 then drives the sports shoe TPU trim sample to gradually become a flat state, and the No. 2 spring telescopic rod 92 is driven to reciprocate up and down during the rotation of the toothed disk 122 located on the No. 2 mounting seat 5, and then indirectly pulls the sports shoe TPU trim sample to bend. The degree of bending of the sports shoe TPU trim sample can be adjusted by adjusting the lever 84 to be located in different sockets 125.

[0041] See also Figure 1 , Figure 2 and Figure 3 In this embodiment, the combined mechanism 10 includes two electric sliders 101 symmetrically slidably connected to the upper end surface of the detection platform 1, a door frame 102 is fixedly connected between the two electric sliders 101, an electric telescopic frame 103 is installed on the lower end surface of the transverse section of the door frame 102, and the front end surfaces of the No. 1 mounting seat 4 and the No. 2 mounting seat 5 are fixedly connected with an extension rod 104, and the front end of the extension rod 104 is hinged to the electric telescopic frame 103.

[0042] When it is necessary to conduct wear resistance and bending tests on the sports shoe TPU trim sample at the same time, the electric telescopic frame 103 is controlled to retract, and the electric telescopic frame 103 then drives the No. 1 mounting seat 4 and the No. 2 mounting seat 5 to move closer to each other through the extension rod 104, and the No. 1 mounting seat 4 and the No. 2 mounting seat 5 then drive their respective I-shaped pressure plates 83 and I-shaped clamps 94 to move closer to each other, and the two adjacent I-shaped pressure plates 83 move closer to each other to the position of the No. 2 mounting seat 5 located between the two No. 1 mounting seats 4, that is, the two adjacent I-shaped pressure plates 83 move to the upper surface of the sports shoe TPU trim sample directly below the No. 2 mounting seat 5, and when the two adjacent No. 2 mounting seats 5 move closer to each other, they will drive the adjacent I-shaped clamps 94 to be clamped on the sports shoe TPU trim sample directly below the No. 1 mounting seat 4.

[0043] When the subsequent dynamic wear measuring mechanism 8 and the adjustable bending measuring mechanism 9 are in operation, the I-shaped pressing plate 83 will apply downward pressure to all the sports shoe TPU trim samples to perform a wear resistance test on all the sports shoe TPU trim samples. When the I-shaped clamp 94 moves upward, it will pull all the sports shoe TPU trim samples to bend upward, so that the sports shoe TPU trim samples in friction can be subjected to a bending test. After the bending test, the I-shaped pressing plate 83 will press the sports shoe TPU trim samples again, so that the sports shoe TPU trim samples can be subjected to wear resistance and bending tests alternately. The sports shoe TPU trim samples can be subjected to wear resistance and bending tests separately or combined with wear resistance and bending tests according to needs.

[0044] See also Figure 1-Figure 7 In addition, the present invention also provides a method for detecting the quality of sports shoe TPU trims, comprising the following steps: S1: selecting a sports shoe TPU trim sample of a universal sample size, and the sample thickness should be consistent with the actual product, and then using a clamping mechanism 6 to clamp the sample.

[0045] S2: The dynamic wear measuring mechanism 8 and the adjustable bending measuring mechanism 9 are controlled by the combined mechanism 10 to operate separately, and the wear resistance and bending performance tests are respectively performed on the sports shoe TPU trim samples.

[0046] S3: The dynamic wear measuring mechanism 8 and the adjustable bending measuring mechanism 9 are controlled by the combined mechanism 10 to operate together, and a combined wear and bending test is performed on the sports shoe TPU trim sample.

[0047] S4: Finally, use a microscope or a magnifying glass to observe whether there are cracks, breaks or layer peeling on the surface of the sports shoe TPU trim samples after two different tests.
