Description

Technical Field

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

[0002] Security shoes generally refer to footwear worn in different work environments to protect the feet and legs from foreseeable injuries. As the part that comes into contact with the ground, the sole must have strong abrasion resistance. Therefore, after security shoes are manufactured, it is particularly important to test the abrasion resistance of the sole.

[0003] Current methods for testing the abrasion resistance of shoe soles typically involve manually holding sandpaper or a file and repeatedly polishing the sole back and forth. The degree of wear is then observed after a certain number of polishing sessions or over a certain period to determine the abrasion resistance of the sole. However, manual polishing is laborious, and workers are prone to fatigue towards the end, leading to a decrease in polishing effectiveness. Furthermore, during the polishing process, debris from the sole adheres to the surface of the file or sandpaper, reducing the polishing effect and consequently affecting the abrasion resistance test of security shoe soles.

[0014] 1. This invention involves placing a pair of security shoes to be tested into shoe boxes on the left and right sides, adjusting the shoes to their correct positions. Then, a motor is started, driving a rotating frame to rotate. This rotating frame, in turn, drives the fixed frames on both sides and the shoe boxes to rotate. During the rotation, a grinding mechanism and a pressurizing mechanism are activated. The pressurizing mechanism applies a certain force to the security shoes in the shoe boxes, ensuring the soles of the shoes fit tightly against the surface of the grinding mechanism. The grinding mechanism then grinds the soles and cleans away any debris.

[0025] Please see Figures 1-7 This invention provides a technical solution: a wear resistance testing device for security shoes, comprising a base plate 1, a motor 2 and a support frame 3 fixedly connected to the upper surface of the base plate 1; a rotating frame 4 fixedly connected to the upper end of the output shaft of the motor 2, the rotating frame 4 being rotatably connected to the support frame 3, and a shoe box 5 and a fixed frame 6 symmetrically arranged on the left and right sides of the rotating frame 4, both the shoe box 5 and the fixed frame 6 being fixedly connected to the rotating frame 4; a grinding mechanism is provided on the surface of the fixed frame 6, which is used to grind the sole of the security shoes inside the shoe box 5 and can automatically clean up the grinding debris; a pressure mechanism is provided on the surface of the shoe box 5, which is used to apply pressure to the security shoes inside the shoe box 5 when the grinding mechanism starts grinding, so that the sole of the security shoes can fit tightly with the grinding mechanism;

[0026] In the workplace, security shoes generally refer to footwear worn in various work environments to protect the feet and legs from foreseeable injuries. As the part in contact with the ground, the sole must possess strong abrasion resistance. Therefore, testing the abrasion resistance of the soles is particularly important after security shoes are manufactured. Current methods for testing sole abrasion resistance typically involve manually holding sandpaper or a file and repeatedly grinding the sole back and forth. The degree of wear is observed after a certain number of grinding sessions or over a certain period to determine the sole's abrasion resistance. However, manual grinding is laborious, and workers easily become fatigued towards the end, leading to poor grinding results. Furthermore, during grinding, debris from the sole adheres to the surface of the file or sandpaper, reducing the grinding effect and thus affecting the abrasion resistance test of the security shoe sole. This new device places a pair of security shoes to be tested into shoe boxes 5 on the left and right sides, and adjusts the shoes... Position the shoe correctly; then start motor 2, which drives the rotating frame 4 to rotate. The rotating frame 4 then drives the fixed frames 6 on both sides and the shoe box 5 to rotate with it. During the rotation of the rotating frame 4, the grinding mechanism and the pressurizing mechanism will operate. The pressurizing mechanism will apply a certain force to the security shoe inside the shoe box 5, so that the sole of the security shoe can be tightly attached to the surface of the grinding mechanism. The grinding mechanism will then grind the sole that is in contact with it, and clean up the grinding debris in time. After the motor 2 drives the rotating frame 4 to rotate for a certain period of time, stop motor 2. At this time, the grinding mechanism and the pressurizing mechanism will stop operating, and the security shoe can be taken out. The quality of the sole can be judged by observing the wear of the sole. This device has a simple structure, is easy to use, and can automatically complete the grinding of the sole, which can effectively save manpower. At the same time, it can automatically and timely clean up the grinding debris during grinding, which can effectively ensure the grinding effect.

[0027] As a further aspect of the present invention, the polishing mechanism includes a polishing disc 7. Slide rods 8 are symmetrically fixedly connected to the upper and lower sides of the surface of the polishing disc 7 away from the shoe box 5. The slide rods 8 are slidably connected to the fixing frame 6. The surface of the fixing frame 6 is provided with a driving mechanism, which is used to drive the polishing disc 7 to move back and forth continuously. During operation, when it is necessary to polish the sole of the shoe, the two slide rods 8 on the surface of the fixing frame 6 can be driven to slide back and forth continuously by activating the driving mechanism. When the two slide rods 8 slide back and forth, they can drive the polishing disc 7 to move back and forth, thereby achieving the effect of polishing the sole of the shoe.

[0028] As a further embodiment of the present invention, the driving mechanism includes a first bevel gear 9 and a first synchronous pulley 10, which are coaxially fixedly connected and the first synchronous pulley 10 is rotatably connected to the fixed frame 6; a bevel gear ring 11 is fixedly connected to the surface of the support frame 3, and the first bevel gear 9 meshes with the bevel gear ring 11; the first synchronous pulley 10 is located at a position slightly below the center of the fixed frame 6; second synchronous pulleys 12 are symmetrically rotatably connected to the front and rear sides of the surface of the fixed frame 6, and a synchronous belt 13 is provided on the surface of the first synchronous pulley 10, which meshes with both the first synchronous pulley 10 and the second synchronous pulleys 12 on the front and rear sides; reciprocating screws 14 are symmetrically rotatably connected to the front and rear sides of the surface of the fixed frame 6, and both the front and rear reciprocating screws 14 are threadedly engaged with the grinding disc 7; a second bevel gear 15 is fixedly connected to the side of the reciprocating screws 14 away from each other on the front and rear sides, and a third bevel gear 16 meshes with the surface of the second bevel gear 15, and both the second bevel gear 15 and the third bevel gear 16 are rotatably connected to the fixed frame 6; the third bevel gears 16 on the front and rear sides are respectively The first bevel gear 9 is coaxially and fixedly connected to the second synchronous pulley 12 on the front and rear sides. During operation, when the motor 2 drives the rotating frame 4 to rotate, the rotating frame 4 will drive the fixed frame 6 and shoe box 5 on the left and right sides of its surface to rotate with the rotating frame 4. Since the first bevel gear 9 at the bottom of the fixed frame 6 meshes with the bevel gear ring 11, when the rotating frame 4 rotates, it will drive the first bevel gear 9 to move around the bevel gear ring 11. During the movement of the first bevel gear 9, the first bevel gear 9 will drive the first synchronous pulley 10 to rotate. The first synchronous pulley 10 will drive the two second synchronous pulleys 12 on the surface of the fixed frame 6 to rotate through the synchronous belt 13. When the second synchronous pulley 12 rotates, it will drive the third bevel gear 16 connected to it to rotate. When the third bevel gear 16 rotates, it will drive the second bevel gear 15 meshing with it to rotate. The second bevel gear 15 will drive the reciprocating screw 14 connected to it to rotate. When the two reciprocating screws 14 on the surface of the fixed frame 6 rotate, they will drive the two sliding rods 8 to slide back and forth on the surface of the fixed frame 6, thereby driving the grinding disc 7 to move back and forth to grind the sole of the shoe.

[0029] As a further embodiment of the present invention, the pressurizing mechanism includes a push plate 17, which is located inside the shoe box 5 and is in clearance fit with the inner wall of the shoe box 5; a first sliding plate 18 is fixedly connected to the side of the push plate 17 away from the rotating frame 4, and the first sliding plate 18 is slidably connected to the shoe box 5; a weight 19 is provided at the other end of the first sliding plate 18, and a second sliding plate 20 is symmetrically fixedly connected to the front and rear sides of the surface of the weight 19, and the second sliding plate 20 is slidably connected to the shoe box 5; a gear 21 is provided between the first sliding plate 18 and the second sliding plate 20, and the gear 21 is rotatably connected to the shoe box 5. The first sliding plate 18 has two first racks 22 fixedly connected symmetrically to its front and rear sides, and the two first racks 22 mesh with two gears 21 respectively; the second sliding plate 20 has a second rack 23 fixedly connected to its surface, and the second rack 23 meshes with the gears 21; the gears 21 are located in the middle of the first sliding plate 18 and the second sliding plate 20; the first racks 22 are located on the surface of the first sliding plate 18 away from the shoe box 5, and the second racks 23 are located on the surface of the second sliding plate 20 closer to the shoe box 5; the push plate 17 is symmetrically fixedly connected to the front and rear sides of the first sliding plate 18. A first spring 24 is fixedly connected to the shoe box 5, and the other end of the first spring 24 is fixedly connected to the shoe box 5. During operation, when the motor 2 drives the rotating frame 4 to rotate, the rotating frame 4 causes the two shoe boxes 5 on its surface to rotate accordingly. The shoe boxes 5 then move the first sliding plate 18, the second sliding plate 20, and the weight 19 on their surfaces. During this movement, the weight 19 moves outward relative to the shoe box 5 under the action of centrifugal force. The weight 19 then causes the two second sliding plates 20 connected to it to slide outward relative to the shoe box 5. When the second sliding plates 20 move, they move the first sliding plate 18, the second sliding plate 20, and the weight 19 on their surfaces. When the second rack 23 moves, it drives the gear 21 to rotate. When the gear 21 rotates, it drives the first rack 22 to move in the opposite direction to the second rack 23. The first rack 22 drives the first sliding plate 18 to slide. At this time, the first sliding plate 18 drives the push plate 17 to push the security shoe closer to the grinding plate 7, so that the sole of the security shoe can fit against the surface of the grinding plate 7. When the grinding plate 7 moves back and forth to grind, since the grinding surface of the grinding plate 7 is on the outer side, the debris on the surface of the grinding plate 7 will be automatically thrown off under the action of centrifugal force.

[0030] As a further aspect of the present invention, a cover plate 25 is provided on the upper side of the shoe box 5. The cover plate 25 is rotatably connected to the shoe box 5, and the connection point between the cover plate 25 and the shoe box 5 is located on the surface of the shoe box 5 closest to the grinding disc 7. Second springs 26 are symmetrically rotatably connected to the front and rear surfaces of the shoe box 5. A pull rope 27 is fixedly connected to the other end of the second spring 26, and the other end of the pull rope 27 is fixedly connected to the pivot of the cover plate 25. During operation, the cover plate 25 can be kept open by the action of the second spring 26 and the pull rope 27, which makes it easy to put the security shoes into or take them out of the shoe box 5. When the motor 2 drives the rotating frame 4 to rotate, the cover plate 25 will automatically overcome the elastic force of the second spring 26 and rotate to close under the action of centrifugal force, which can prevent the security shoes from falling out. After grinding is completed, the motor 2 is stopped, and the cover plate 25 will automatically open under the action of the second spring 26 and the pull rope 27.

[0031] As a further embodiment of the present invention, a circular groove 28 is provided on the upper surface of the support frame 3; a slider 29 is fixedly connected to the bottom of the shoe box 5 in the fixed frame 6, and the slider 29 is slidably connected to the circular groove 28; during operation, the slider 29 slides in the circular groove 28, which can support the shoe box 5, thereby effectively improving the stability of the shoe box 5.

[0032] As a further embodiment of the present invention, a protective cover 30 is fixedly connected to the upper surface of the base plate 1, and the upper part of the protective cover 30 is located above the weight block 19. During operation, since the motor 2 needs to drive the rotating frame 4 to rotate at high speed when polishing the shoe sole, the risk is relatively high. The protective cover 30 can prevent workers from being injured. At the same time, the protective cover 30 can also prevent the debris thrown out from falling everywhere and polluting the environment.
