Description

Technical Field

[0001] This utility model relates to the technical field of shoe material processing equipment, and specifically to a shoe material tear resistance testing device. Background Technology

[0002] Shoes are composed of uppers, soles, and heels. During the production process, since the uppers are usually made of textiles, the tear resistance of the upper fabric needs to be tested. This test requires the use of a drop weight tear tester.

[0003] As existing technology, Chinese patent CN219870677U proposes a tear resistance testing device for shoe material production. Although it solves the problem that the existing falling hammer tear tester fixture uses a rotating screw to push the clamping plate to fix and disassemble the shoe upper fabric, which is time-consuming, the structure of this technical solution is relatively complex, requires high precision in the production of parts, and is costly. Moreover, when removing the tested fabric, it is necessary to use both hands to rotate two rotating shafts simultaneously to unlock the reverse gears on the rotating shafts. At this time, both hands need to maintain the rotation angle of the two rotating shafts to prevent the torsion spring from elastically returning and locking the reverse gears on the rotating shafts. At the same time, both hands need to pull out the rotating shafts to release the pressure on the clamping plate and remove the fabric by hand. The operation process is relatively cumbersome and easy to get flustered. There is still room for improvement. Utility Model Content

[0004] The purpose of this invention is to provide a device for testing the tear resistance of shoe materials, in order to solve the problems mentioned in the background art.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: a shoe material tear resistance testing device, including a base, a support frame provided on the top side of the base, a fan-shaped hammer rotatably connected to one side of the support frame, and a first clamping assembly, a second clamping assembly, and a limiting plate provided on the other side of the support frame. The first clamping assembly includes a fixing frame, a clamping groove provided on the top of the fixing frame, a fixing block provided in the clamping groove, a sliding hole provided on the fixing block, a movable shaft slidably connected to the sliding hole, a spring sleeved on the movable shaft, one end of the spring connected to the clamping plate, and the other end connected to the fixing frame. The connection includes a shoe upper fabric on the side of the limiting plate facing the clamping plate, which clamps the shoe upper fabric with the clamping plate. A clamping plate is provided at the end of the movable shaft facing the limiting plate. A strip hole is opened on the side wall of the clamping groove away from the limiting plate for the movable shaft to pass through. A rotatable strip plate is provided at the end of the movable shaft near the strip hole. The length and width of the strip plate are both smaller than the length and width of the strip hole, and the length of the strip plate is greater than the width of the strip hole. The second clamping assembly has the same structure as the first clamping assembly. The first clamping assembly and the second clamping assembly are symmetrically arranged about the bisector of the limiting plate.

[0006] Using the above technical solution, under normal conditions, the movable shaft keeps the clamping plate in contact with the limiting plate under the action of the spring. When it is necessary to clamp the upper fabric, pull the movable shaft towards the strip hole until the strip plate passes through the strip hole. Then rotate the strip plate. After the strip plate rotates, because its length is greater than the width of the strip hole, the strip plate can no longer pass through the strip hole. Under the return action of the spring, the strip plate abuts against the outer wall of the strip hole. At this time, both hands can immediately release the movable shaft. Then, the two sides of the upper fabric can be placed between the clamping plate and the limiting plate on the first clamp and the second clamp, respectively. Then rotate the strip plate. After the strip plate rotates, its width is less than the width of the strip hole. Under the return action of the spring, the movable shaft slides with the sliding hole, so that the clamping plate and the limiting plate clamp the upper fabric. At this time, both sides of the upper fabric are clamped at the same time. The above solution has a simple structure, low cost, and simple operation steps, avoiding confusion and making it more practical.

[0007] As a further optimization of this utility model, the limiting plate is embedded with a first magnet, and the clamping plate is embedded with a second magnet that can be attracted to the first magnet.

[0008] Using the above technical solution, the first magnet and the second magnet attract each other, making the clamping plate and the limiting plate firmly attached, thereby tightly holding the shoe upper fabric.

[0009] As a further optimization of this utility model, the end of the clamping plate facing the limiting plate is provided with several protruding anti-slip blocks.

[0010] By adopting the above technical solutions, the anti-slip block increases the friction between the clamp and the surface of the shoe upper fabric, preventing the fabric from sliding laterally.

[0011] As a further optimization of this utility model, the strip plate is provided with a pull rod that passes through the strip hole, and the surface of the pull rod is provided with a plurality of anti-slip grooves.

[0012] By adopting the above technical solutions, a pull rod is installed to facilitate the pulling of the movable shaft by the testing personnel, and the anti-slip groove can improve the anti-slip properties of the pull rod surface.

[0013] The beneficial effects of this utility model are as follows: Under normal conditions, the movable shaft keeps the clamping plate in contact with the limiting plate under the action of the spring. When it is necessary to clamp the shoe upper fabric, pull the movable shaft towards the strip hole until the strip plate passes through the strip hole. Then rotate the strip plate. After the strip plate rotates, because its length is greater than the width of the strip hole, the strip plate can no longer pass through the strip hole. Under the return action of the spring, the strip plate abuts against the outer wall of the strip hole. At this time, both hands can immediately release the movable shaft. Then, the two sides of the shoe upper fabric can be placed between the clamping plate and the limiting plate on the first clamp and the second clamp, respectively. Then rotate the strip plate. After the strip plate rotates, its width is less than the width of the strip hole. Under the return action of the spring, the movable shaft slides with the sliding hole, so that the clamping plate and the limiting plate clamp the shoe upper fabric. At this time, both sides of the shoe upper fabric are clamped at the same time. The above solution has a simple structure, low cost, and simple operation steps, which will not cause confusion and is more practical. Attached Figure Description

[0018] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0019] See appendix Figure 1-3The present embodiment of this utility model further includes: a shoe material tear resistance testing device, including a base 1, a support frame on the top side of the base 1, a fan-shaped hammer 12 rotatably connected to one side of the support frame, and a first clamp 2 assembly, a second clamp 3 assembly and a limiting plate 4 on the other side of the support frame. The first clamp 2 assembly includes a fixing frame, a clamping groove is opened above the fixing frame, a fixing block 6 is provided in the clamping groove, a sliding hole 61 is opened on the fixing block 6, a movable shaft 7 is slidably connected to the sliding hole 61, a spring 73 is sleeved on the movable shaft 7, one end of the spring 73 is connected to the clamping plate 5 and the other end is connected to the fixing frame, a shoe upper fabric 8 is provided on the side of the limiting plate 4 facing the clamping plate 5, the clamping plate 5 and the limiting plate 4 clamp the shoe upper fabric 8, further, the limiting plate 4 is embedded with a first magnet 91, the clamping plate 5 is embedded with a second magnet 92 that can be attracted to the first magnet 91, and a plurality of protruding anti-slip blocks 51 are provided on the end of the clamping plate 5 facing the limiting plate 4;

[0020] A clamping plate 5 is provided at one end of the movable shaft 7 facing the limiting plate 4. A strip hole 74 is provided on the side wall of the clamping groove away from the limiting plate 4 for the movable shaft 7 to pass through. A rotatable strip plate 71 is provided at one end of the movable shaft 7 near the strip hole 74. The length and width of the strip plate 71 are both smaller than the length and width of the strip hole 74, and the length of the strip plate 71 is greater than the width of the strip hole 74. Furthermore, a pull rod 72 is provided on the strip plate 71 that passes through the strip hole 74. The surface of the pull rod 72 is provided with several anti-slip grooves.

[0021] The second clamp 3 assembly has the same structure as the first clamp 2 assembly, and the first clamp 2 assembly and the second clamp 3 assembly are arranged symmetrically about the bisector of the limiting plate 4.

[0022] The principle of this utility model is as follows: Under normal conditions, the movable shaft 7 keeps the clamping plate 5 in contact with the limiting plate 4 under the action of the spring 73. When it is necessary to clamp the shoe upper fabric 8, the inspector pulls the movable shaft 7 towards the strip hole 74 through the pull rod 72 until the strip plate 71 passes through the strip hole 74. The anti-slip groove can improve the anti-slip properties of the surface of the pull rod 72. Then, the strip plate 71 is rotated. After the strip plate 71 is rotated, because its length is greater than the width of the strip hole 74, the strip plate 71 cannot pass through the strip hole 74 again. Under the return action of the spring 73, the strip plate 71 abuts against the outer wall of the strip hole 74.

[0023] At this point, both hands can immediately release the movable shaft 7. Then, the two sides of the shoe upper fabric 8 can be placed between the clamping plate 5 and the limiting plate 4 on the first clamp 2 and the second clamp, respectively. Then, rotate the strip plate 71. After the strip plate 71 rotates, its width is less than the width of the strip hole 74. The movable shaft 7 slides with the sliding hole 61 under the restoring action of the spring 73, so that the clamping plate 5 and the limiting plate 4 clamp the shoe upper fabric 8. At this time, both sides of the shoe upper fabric 8 are clamped at the same time. The first magnet 91 and the second magnet 92 attract each other, so that the clamping plate 5 and the limiting plate 4 are firmly attached, thereby clamping the shoe upper fabric 8 tightly. The anti-slip block 51 increases the friction of the clamping plate 5 on the surface of the shoe upper fabric 8, preventing the fabric from sliding laterally.

[0024] The above solution has a simple structure, low cost, and easy operation steps, making it more practical and less cumbersome.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
