Description

Technical Field

[0001] This utility model relates to the field of footwear production technology, and in particular to a footwear abrasion testing machine with pressure adjustment function. Background Technology

[0002] In the field of footwear manufacturing technology, the abrasion performance of shoe materials is one of the key indicators for measuring shoe quality and lifespan, directly affecting the consumer experience and the product's market competitiveness. Therefore, precise abrasion testing of shoe materials is an indispensable part of the footwear production process.

[0003] Currently, existing shoe abrasion testing machines have certain limitations in practical applications. Some devices lack effective pressure adjustment functions and cannot flexibly adjust the pressure of the abrasion rollers on the specimens according to the characteristics of different shoe materials (such as leather, rubber, and fabric). This leads to deviations between the test results and the actual usage conditions of the materials, making it difficult to accurately reflect the differences in abrasion resistance of different shoe materials.

[0004] While some other testing machines possess pressure adjustment capabilities, their adjustment accuracy is low, pressure monitoring is not real-time, and the pressure roller position is prone to shifting during adjustment, affecting the stability and reliability of test data. Therefore, we designed a shoe abrasion testing machine with pressure adjustment functionality. Utility Model Content

[0005] This utility model discloses a shoe abrasion testing machine with pressure adjustment function. To achieve the above objective, this utility model adopts the following technical solution: A shoe abrasion testing machine with pressure adjustment function includes an operating table, the surface of which is provided with a testing mechanism and a specimen limiting mechanism; The testing mechanism includes a first adjusting shell fixedly connected to the surface of the operating table. A horizontal adjusting screw is rotatably connected to the inner wall of the first adjusting shell. A horizontal moving block is threadedly connected to the surface of the horizontal adjusting screw. A second adjusting shell is fixedly connected to the upper surface of the horizontal moving block. A driving screw is rotatably connected to the inner wall of the second adjusting shell. An extension frame is threadedly connected to the surface of the driving screw. A pressure roller assembly is provided on the surface of the extension frame.

[0006] In a preferred embodiment, the pressure roller assembly includes a movable frame, a rotating shaft rotatably connected to the inner side of the movable frame, a grinding roller fixedly connected to the surface of the rotating shaft, a rotary motor fixedly mounted on one side of the movable frame, and a rotating shaft of the rotary motor fixedly connected to one end of the rotating shaft.

[0007] In a preferred embodiment, a limiting movable rod is fixedly connected to the upper surface of the movable frame, and a sliding through hole matching the limiting movable rod is opened on the surface of the extension frame. The limiting movable rod is slidably connected to the inner wall of the sliding through hole, and a limiting baffle is fixed to the top end of the limiting movable rod.

[0008] In a preferred embodiment, the extension frame has a rectangular groove inside, the pressure roller assembly also includes a pressure sensor fixedly installed on the inner wall of the rectangular groove, a pressure sensing plate is fixedly connected to the surface of the limiting movable rod, the pressure sensing plate overlaps with the sensing end of the pressure sensor, and a guide rod is fixedly connected to the inner wall of the rectangular groove.

[0009] In a preferred embodiment, the surface of the pressure sensing plate is provided with a guide hole that matches the guide rod, and the pressure sensing plate is slidably connected to the surface of the guide rod through the guide hole.

[0010] In a preferred embodiment, a first drive motor is fixedly connected to the end of the first adjusting shell, the rotation shaft of the first drive motor extends into the interior of the first adjusting shell and is fixedly connected to the end of the horizontal adjusting screw, and a second drive motor is fixedly connected to the top of the second adjusting shell, the rotation shaft of the second drive motor extends into the interior of the second adjusting shell and is fixedly connected to the top of the drive screw.

[0011] In a preferred embodiment, the specimen limiting mechanism includes four symmetrically arranged storage slots on the upper surface of the operating table. The inner wall of the storage slot is rotatably connected to a winding wheel via a rotating shaft and a coil spring. The surface of the winding wheel is wrapped with a limiting strap, and two of the limiting straps are symmetrically distributed on the surface of the operating table.

[0012] As can be seen from the above, the shoe abrasion testing machine with pressure adjustment function provided by this utility model has the following technical effects.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 A shoe abrasion testing machine with pressure adjustment function mainly consists of an operating table 1, a testing mechanism 2, a specimen limiting mechanism 3 and a pressure roller assembly 4, which realizes the abrasion test of shoe specimens and has pressure adjustment function.

[0024] The test mechanism 2 is fixedly installed on the surface of the operating table 1 and is the core structure for realizing wear testing and position adjustment. It consists of a first adjusting shell 201, a horizontal adjusting screw 202, a horizontal moving block 203, a second adjusting shell 204, a drive screw 205, an extension frame 206, a first drive motor 207, and a second drive motor 208.

[0025] The first adjusting shell 201 is fixedly connected to the surface of the operating table 1, providing installation and protection space for the horizontal adjustment components. The horizontal adjusting screw 202 is rotatably connected to the inner wall of the first adjusting shell 201, and its two ends are connected to the inner wall of the first adjusting shell 201 through bearings to ensure that the horizontal adjusting screw 202 can rotate stably. The horizontal moving block 203 is threadedly connected to the surface of the horizontal adjusting screw 202, and its two sides are in sliding contact with the inner wall of the first adjusting shell 201, restricting the horizontal moving block 203 from rotating synchronously with the horizontal adjusting screw 202 and allowing it to move only along the axial direction of the horizontal adjusting screw 202. The second adjusting shell 204 is fixedly connected to the upper surface of the horizontal moving block 203 and moves together with the horizontal moving block 203, providing an installation carrier for components such as the drive screw 205. The drive screw 205 is rotatably connected to the inner wall of the second adjusting shell 204, and its upper and lower ends are connected to the inner wall of the second adjusting shell 204 through bearings to ensure the stable rotation of the drive screw 205.

[0026] The extension frame 206 is threadedly connected to the surface of the drive screw 205. The two sides of the extension frame 206 slide in contact with the inner wall of the second adjusting shell 204, so that the extension frame 206 cannot rotate synchronously with the drive screw 205, but can only move up and down along the axial direction of the drive screw 205. The first drive motor 207 is fixedly connected to the end of the first adjusting shell 201, and its rotating shaft extends into the interior of the first adjusting shell 201 and is fixedly connected to the end of the horizontal adjusting screw 202. The rotation of the first drive motor 207 drives the horizontal adjusting screw 202 to rotate, thereby driving the horizontal moving block 203 to move, realizing the horizontal adjustment of the test mechanism 2. This structure allows the pressure roller assembly 4 to flexibly align with different test positions of the specimen, improving the applicability of the equipment.

[0027] The second drive motor 208 is fixed to the top of the second adjustment housing 204. Its rotating shaft extends into the interior of the second adjustment housing 204 and is fixedly connected to the top of the drive screw 205. When the second drive motor 208 is working, it drives the drive screw 205 to rotate, causing the extension frame 206 to move up and down, thereby adjusting the height of the pressure roller assembly 4. This facilitates control of the contact state between the pressure roller 402 and the specimen, making the operation convenient and efficient.

[0028] The pressure roller assembly 4 is disposed on the surface of the extension frame 206 and is the component that directly contacts the specimen for wear testing. It includes a movable frame 401, a pressure roller 402, a rotary motor 403, a limiting movable rod 404, a limiting baffle 405, a pressure sensor 407, a pressure sensing plate 408, and a guide rod 409. The movable frame 401 is located below the extension frame 206, and a rotating shaft is rotatably connected to its inner side. The two ends of the rotating shaft are connected to the inner wall of the movable frame 401 through bearings.

[0029] The grinding wheel 402 is fixedly connected to the surface of the rotating shaft and rotates together with the rotating shaft. The wear test is achieved through friction with the specimen. The rotary motor 403 is fixedly installed on one side of the movable frame 401, and its rotating shaft is fixedly connected to one end of the rotating shaft. It provides power for the rotation of the rotating shaft and the grinding wheel 402, ensuring the continuous operation of the wear test. The limiting rod 404 is fixedly connected to the upper surface of the movable frame 401. The surface of the extension frame 206 is provided with a sliding through hole that matches the limiting rod 404. The limiting rod 404 is slidably connected to the inner wall of the sliding through hole, so that the movable frame 401 can move up and down relative to the extension frame 206, while limiting the horizontal displacement of the movable frame 401, ensuring the stable operation of the grinding wheel 402. The limiting baffle 405 is fixed to the top of the limiting rod 404, which can prevent the limiting rod 404 from disengaging from the sliding through hole and ensure the integrity of the structure.

[0030] The extension frame 206 has a rectangular slot 406 inside, providing installation space for components such as the pressure sensor 407. The pressure sensor 407 is fixedly installed on the inner wall of the rectangular slot 406 to sense pressure signals. The pressure sensing plate 408 is fixedly connected to the surface of the limiting rod 404 and overlaps with the sensing end of the pressure sensor 407. When the movable frame 401 moves up and down, the limiting rod 404 drives the pressure sensing plate 408 to move synchronously, so that the pressure sensing plate 408 generates different pressures on the pressure sensor 407. The pressure sensor 407 transmits the pressure signal to the control system to realize real-time monitoring of the pressure of the grinding wheel 402, which facilitates precise pressure adjustment, meets the testing requirements of different shoe materials, and improves the accuracy of test data.

[0031] The guide rod 409 is fixedly connected to the inner wall of the rectangular groove 406. The surface of the pressure sensing plate 408 is provided with a guide through hole that matches the guide rod 409. The pressure sensing plate 408 is slidably connected to the surface of the guide rod 409 through the guide through hole. The guide rod 409 provides guidance for the movement of the pressure sensing plate 408, preventing the pressure sensing plate 408 from deviating during the movement, ensuring the accuracy of pressure sensing, and further improving the precision of pressure regulation.

[0032] The specimen limiting mechanism 3 is disposed on the surface of the operating table 1 for fixing the specimen to be tested, and includes a storage slot 301, a winding wheel 302, and a limiting strap 303. Four storage slots 301 are symmetrically opened on the upper surface of the operating table 1 to provide storage space for the winding wheel 302 and the limiting strap 303; the winding wheel 302 is rotatably connected to the inner wall of the storage slot 301 through a rotating shaft and a coil spring, and the elastic force of the coil spring makes the winding wheel 302 tend to retract the limiting strap 303.

[0033] The limiting straps 303 are wrapped around the surface of the take-up reel 302, and the two limiting straps 303 are symmetrically distributed on the surface of the operating table 1. When in use, the limiting straps 303 can be pulled out and fixed to the specimen. Under the action of the coil spring, the limiting straps 303 can fit tightly against the specimen, and fix the specimen firmly from multiple directions, preventing the specimen from shifting during the test and ensuring the stability of the test process. At the same time, it is suitable for specimens of different sizes, enhancing the versatility of the equipment.

[0034] Working Principle: In use, first, place the test specimen on the surface of the operating table 1. Based on the specimen's size and shape, pull out the limiting strap 303 from the storage slot 301 to secure the specimen firmly. Under the action of the coil spring, the limiting strap 303 tightly adheres to the specimen, ensuring that the specimen will not move during the test. Next, start the first drive motor 207. The first drive motor 207 drives the horizontal adjusting screw 202 to rotate. Under the action of the horizontal adjusting screw 202, the horizontal moving block 203 moves horizontally along the first adjusting shell 201, thereby driving the second adjusting shell 204, the extension frame 206, and the pressure roller assembly 4 to move horizontally together, adjusting the pressure roller 402 to directly above the test position of the specimen. Then, start the second drive motor 208. The second drive motor 208 drives the drive screw 205 to rotate. Under the action of the drive screw 205, the extension frame 206 moves downward along the second adjusting shell 204, causing the pressure roller 402 to gradually approach and contact the specimen. During the contact between the grinding wheel 402 and the specimen, the movable frame 401 moves upward under the reaction force of the specimen, causing the limiting movable rod 404 and the pressure sensing plate 408 to move upward together. The pressure sensing plate 408 generates pressure on the pressure sensor 407, which transmits a real-time pressure signal to the control system. Based on the signal fed back by the pressure sensor 407, the operator can precisely adjust the downward movement distance of the extension frame 206 by controlling the rotation direction and angle of the second drive motor 208, thereby adjusting the pressure of the grinding wheel 402 on the specimen to the required value. After the pressure adjustment is completed, the rotary motor 403 is started, which drives the rotating shaft and the grinding wheel 402 to rotate. The grinding wheel 402 rubs against the surface of the specimen, simulating the wear and tear of shoes during actual use, and conducting an abrasion test. During the test, if the test position needs to be changed, the first drive motor 207 can be restarted to adjust the horizontal position of the pressure roller assembly 4; if the pressure needs to be adjusted, the height of the extension frame 206 can be adjusted by the second drive motor 208. The pressure sensor 407 monitors the pressure change in real time to ensure that the test pressure always meets the test requirements.

[0035] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
