Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of leather shoe testing devices, specifically a testing device for leather shoe bending resistance. Background Technology
[0002] Leather shoes, made with natural leather uppers and soles of leather, rubber, or plastic, and manufactured through processes such as stitching, gluing, or injection molding, possess breathable, moisture-wicking properties and good hygiene, making them a high-end choice among various footwear. During daily wear, the toe area of the shoe is prone to wrinkling due to frequent bending during walking. Therefore, after leather shoes are manufactured, their bending resistance needs to be evaluated using testing equipment to assess their actual wear quality. However, current testing equipment has many limitations. Most only apply simple pressure to the shoe to achieve bending, and the bending point is fixed at a single point, making it difficult to effectively test other areas. Furthermore, tests are usually conducted at room temperature, failing to consider the impact of different temperatures on the shoe's bending resistance, greatly reducing the comprehensiveness and applicability of the tests, and failing to accurately simulate the conditions of leather shoes under complex real-world usage scenarios.
[0003] Application number CN202211631686.5 discloses a testing device for the bending resistance of leather shoes, belonging to the field of leather shoe testing technology. It solves the problems of current testing devices being unable to perform tests at different temperatures and being inconvenient for testing leather shoes in different positions. This testing device for the bending resistance of leather shoes includes a housing. A first screw is rotatably connected to the front and rear of the right side of the housing cavity. A support plate is threadedly connected to the surface of the first screw. A drive structure for rotating the support plate is provided on the top of the housing. This invention allows for bending resistance testing of leather shoes at different positions, thus improving applicability. It also allows for temperature adjustment, enabling bending resistance testing of leather shoes at different temperatures, thereby improving the testing effect. Furthermore, it allows for the classification and collection of tested leather shoes for convenient subsequent handling by staff. However, a shortcoming is that the device is not yet able to perform bending tests on different positions of the shoe, making it unable to adjust for different positions when dealing with spliced soles made of different materials.

The pushing of the pneumatic push rod 304 passes through the middle of the pushing translation plate 303. A bending extrusion plate 305 is fixedly mounted at the end of the pneumatic push rod 304. The adjusting bending assembly 3 uses the regulating threaded push rod 302 and the pneumatic push rod 304 to realize the bending operation of the leather shoe, thereby simulating the bending situation of the leather shoe in actual use.
[0027] By installing the adjustable bending component 3 on the device, the device can be adjusted to different positions when performing bending tests on different parts of the shoe, thus ensuring the flexibility of the device during application.
[0028] The support assembly 1 includes a workbench 101, a worktable 102 is fixedly installed at the top center of the workbench 101, an installation side plate 103 is fixedly installed on the outer wall of the worktable 102, and limit slide rails 104 are fixedly installed on both sides of the top of the worktable 102, and a limit rack 105 is fixedly installed on the outer wall of one side of the limit slide rail 104.
[0029] The limiting movement assembly 2 includes a rotary motor 201, which is fixedly installed on the top side of the connecting support plate 202. A drive gear 203 is fixedly installed on the bottom of the rotary motor 201. The drive gear 203 is correspondingly arranged on the bottom side of the connecting support plate 202 and is located on the outside of the limiting rack 105. The limiting rack 105 and the drive gear 203 mesh with each other. The rear wall of one side of the connecting support plate 202 is connected to one end of the limiting chain 205 through a connecting plate 204. The other end of the limiting chain 205 is fixedly installed on the outer wall of the fixing plate 206.

[0030] The bottom sides of the linkage support plate 202 are slidably mounted on the top of the limit slide rail 104 through the opening of the movable limit groove 2021. The rotary motor 201 of the limit moving component 2 drives the drive gear 203 to mesh with the limit rack 105, thereby driving the linkage support plate 202 to move along the limit slide rail 104.
[0031] The pneumatic displacement assembly 4 includes a pneumatic rod 401, which is fixedly installed on the top rear side of the mounting plate 103. A translation plate 402 is fixedly installed at the end of the pneumatic rod 401. The bottom of the translation plate 402 is slidably installed inside the limiting slide groove 1031 via a slider. A matching clamping plate 403 is fixedly installed at the front end of the translation plate 402. The matching clamping plate 403 is correspondingly set on the top of the workbench 102. The pneumatic rod 401 of the pneumatic displacement assembly 4 pushes the translation plate 402 to slide within the limiting slide groove 1031.
[0032] The adjusting clamping assembly 5 includes a mounting base 501, which is fixedly installed on the top side of the workbench 102. A rotating base 502 is fixedly installed on the outer side of the top of the mounting base 501. A threaded rod 503 is installed in the middle of the rotating base 502 by means of a thread. An active clamping plate 504 is fixedly installed on the inner end of the threaded rod 503. The adjusting clamping assembly 5 clamps the leather shoe by rotating the threaded rod 503 to drive the active clamping plate 504.
[0033] This shoe bending resistance testing device is based on the principles of mechanical transmission and pneumatic control. A stable support platform is provided by the support assembly 1. The device utilizes the coordinated operation of the limiting movement assembly 2, the pneumatic displacement assembly 4, the adjusting clamping assembly 5, and the adjusting bending assembly 3 to achieve shoe clamping, displacement adjustment, and bending testing. The rotary motor 201 of the limiting movement assembly 2 drives the active gear 203 to mesh with the limiting rack 105, causing the connecting support plate 202 to move along the limiting slide rail 104. The pneumatic rod 401 of the pneumatic displacement assembly 4 pushes the translation plate 402 to slide within the limiting slide groove 1031. The adjusting clamping assembly 5 uses a rotating threaded rod 503 to drive the active clamping plate 504 to clamp the shoe. The adjusting bending assembly 3 uses the adjusting threaded push rod 302 and the pneumatic push rod 304 to perform the bending operation on the shoe, thereby achieving the bending test. To simulate the bending conditions of leather shoes in actual use and test their bending resistance, the bending resistance testing device is placed on a stable working area during the workflow. It is checked whether each component is firmly installed, whether the sliding parts such as the limit slide rail 104 and the limit slide groove 1031 are smooth, and whether the pneumatic components such as the pneumatic rod 401 and the pneumatic push rod 304 are properly connected and the air supply is stable. The leather shoe to be tested is placed on the workbench 102, between the adjusting clamping component 5 and the pneumatic displacement component 4. By rotating the threaded rod 503 of the adjusting clamping assembly 5, the active clamping plate 504 moves towards the shoe under the limit of the rotating seat 502 until the shoe is firmly clamped between the active clamping plate 504 and the matching clamping plate 403 of the pneumatic displacement assembly 4. The rotary motor 201 of the limiting movement assembly 2 is then activated, driving the active gear 203 to rotate. Since the active gear 203 meshes with the limiting rack 105, the connecting support plate 202 slides on the limiting slide rail 104 through the moving limiting grooves 2021 on both bottom sides, thereby driving the adjusting bending assembly 3 installed on the connecting support plate 202. The horizontal movement is adjusted to change its relative position to the shoe, ensuring that the bending assembly 3 is in the appropriate test position. The pneumatic rod 401 of the pneumatic displacement assembly 4 is activated, pushing the translation plate 402. The slider at the bottom of the translation plate 402 slides within the limiting groove 1031 of the mounting plate 103, thereby moving the matching clamp 403 to further fine-tune the shoe's position, ensuring it is in the precise test position. By rotating the adjusting threaded push rod 302 of the bending assembly 3, the translation plate 303 is pushed to move horizontally under the limit of the mounting support plate 301, adjusting the distance between the translation plate 303 and the shoe. Next, the pneumatic push rod 304 is activated, pushing the bending extrusion plate 305 to apply pressure to the shoe, causing it to bend, simulating the bending situation in actual wear. During the test, the bending action can be repeated multiple times according to the test requirements, and the number of times the leather shoes are bent and whether any damage occurs should be recorded. After the test is completed, the power components such as the pneumatic push rod 304, pneumatic rod 401 and rotary motor 201 should be turned off.Then, rotate the threaded rod 503 of the adjusting clamping assembly 5 in the opposite direction to loosen the active clamping plate 504, remove the tested leather shoe, clean the workbench 102, and restore the device to its initial state for the next test.
