Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0024] Reference Figure 1 - Figure 3, an embodiment provided by the present invention: a leather shoe leather mold stretching device, comprising a cutting device body 1, the cutting device body 1 is a prior art, the leather can be spread on its upper surface, and the leather can be cut by starting the cutting device on the cutting device body 1. The worker can adjust the shape and size of the cut according to the needs. A covering film 4 is provided on the right surface of the cutting device body 1. The covering film 4 is a prior art, which is rolled up on the outer wall of the winding roller. When in use, the worker can pull one end of the covering film 4 to cover the upper surface of the leather, which helps to better shape the leather. A stretching component 2 is provided on the top of the front surface of the cutting device body 1 of the covering film 4. The upper surface of the cutting device body 1 A fixed component 3 is arranged on the right side, and the stretching component 2 includes an electric slide rail 21. The electric slide rail 21 is a prior art. By starting it, the slider 22 can be driven to move linearly to ensure that the covering film 4 can be pulled out quickly, thereby improving practicality. The electric slide rail 21 is fixedly connected to the top of the front surface of the cutting equipment body 1, and a slider 22 is arranged on the right end of the front surface of the electric slide rail 21. A slide bar 23 is slidably connected to the upper surface of the front end of the slider 22. When the height of the slide bar 23 is adjusted, the splint 1 26 and the splint 27 will also move accordingly, so that leather materials of different thicknesses can be coated, thereby improving applicability. A through groove 210 is provided on the right surface of the top of the slide bar 23.
[0025] Reference Figure 1 - Figure 2 , Figure 4 The fixing assembly 3 includes a support frame 31, the inner wall of the bottom end of the support frame 31 is fixedly connected to the right side of the electric slide rail 21 near the front surface of the cutting device body 1, and a rectangular groove 38 is opened on the inner wall of the support frame 31, and a moving block 34 is slidably connected to the inner wall of the rectangular groove 38. The rear surface of the moving block 34 is rotatably connected to a roller column 32. When the covering film 4 is pulled, the roller column 32 will rotate to ensure the continuity of the pulling out of the covering film 4. The roller column 32 contacts the upper surface of the cutting device body 1. The front end of the upper surface of the support frame 31 is slidably connected with a pull rod 33. Before laminating, the pull rod 33 can be pulled to prevent the roller column 32 from contacting the device. At this time, one end of the covering film 4 is passed through the bottom of the roller column 32, and then the pull rod 33 is loosened. At this time, it will fix the covering film 4 under the action of the spring 2 35, ensuring that the pulled covering film 4 is always in a taut state, thereby improving the flatness of the laminating. The lower surface of the pull rod 33 is fixedly connected to the upper surface of the moving block 34.
[0026] Reference Figure 2 - Figure 3 , Figure 5The outer wall of the slide bar 23 is fixedly connected with a clamping plate 27 near the upper side of the slider 22, and the outer wall of the slide bar 23 is slidably connected with a clamping plate 1 26 near the upper side of the clamping plate 27. The upper surface of the rear end of the clamping plate 27 and the lower surface of the rear end of the clamping plate 1 26 are set to rubber material, which ensures the stability of the movement of the covering film 4 while avoiding damage to the covering film 4. A threaded rod 28 is rotatably connected to the upper surface of the slide bar 23. The threaded rod 28 is a prior art, which is a rod-shaped structure with threads on the outer wall. When the threaded rod 28 is rotated, the connecting block 29 connected to its outer wall will move linearly according to its axial direction. At the same time, it has a certain self-locking property to ensure the stability of the structure. The outer wall of the threaded rod 28 is threadedly connected with a connecting block 29, and the right end of the connecting block 29 is slidably connected to the inner wall of the through groove 1 210, and the right surface of the threaded rod 28 is fixedly connected to the inner wall of the clamping plate 1 26.
[0027] Reference Figure 2 - Figure 3 The front surface of the slider 22 is penetrated by a limit rod 24 that is slidably connected. The front surface of the slider 23 is provided with multiple groups of grooves, and the number of the grooves is multiple. The multiple groups of grooves are provided to ensure that when the limit rod 24 is adjusted to different heights, it can be limited by the limit rod 24. The rear surface of the limit rod 24 contacts the inner wall of the groove. The outer wall of the limit rod 24 is sleeved with a spring 25. The spring 25 always pulls the limit rod 24 backward through its own elasticity to ensure the stability of its limit. One end of the spring 25 is fixedly connected to the front surface of the slider 22, and the other end of the spring 25 is fixedly connected to the rear surface of the limit rod 24.
[0028] Reference Figure 2 , Figure 4 A through slot 2 37 is provided on the upper surface of the support frame 31, and a cutting knife 36 is slidably connected to the inner wall of the through slot 2 37. A spring 2 35 is sleeved on the outer wall of the pull rod 33. The spring 2 35 itself has a certain elasticity. It always pushes the moving block 34 to move downward through its own elasticity to ensure the stability of the roller 32 fixing the covering film 4. One end of the spring 2 35 is fixedly connected to the upper surface of the moving block 34, and the other end of the spring 2 35 is fixedly connected to the inner wall of the rectangular groove 38.
[0029] Working principle: When only leather needs to be processed, the leather can be spread on the upper surface of the cutting equipment body 1, and the cutting device on the cutting equipment body 1 can be used to cut the shape and size of the leather according to needs. Then, the worker pulls one end of the covering film 4 to pull it out from the outer wall of the winding roller and cover the upper surface of the leather to help better shape the leather.
[0030] When pulling the covering film 4, it is only necessary to pull one end of the covering film 4 and place it between the clamping plate 1 26 and the clamping plate 27, and then rotate the threaded rod 28. At this time, the connecting block 29 will move linearly with the rotation of the threaded rod 28, and at the same time, the connecting block 29 will drive the clamping plate 1 26 to move, so that the clamping plate 1 26 and the clamping plate 27 can fix one end of the connecting plate covering film 4. At this time, the electric slide rail 21 is started to drive the slider 22 to move, and the slider 22 will drive the slide rod 23 to move, and the clamping plate 1 26 and the clamping plate 27 will also move accordingly. When the height of the two plywoods 26 and 27 needs to be adjusted according to the thickness of the leather, the limit rod 24 is pulled, and the limit rod 24 will pass through the inner wall of the groove and stretch the spring 1 25 at the same time, and then the slide bar 23 is pushed to adjust the height, and the two plywoods 26 and 27 will also move accordingly. After the adjustment is completed, the limit rod 24 can be loosened, and the spring 1 25 will pull the limit rod 24 through its own elasticity to move in the opposite direction into the inner wall of the groove to limit the slide bar 23.
[0031] When the connecting plate covering film 4 is pulled out, it is necessary to make it pass between the roller 32 and the detection device cutting device body 1. The operation method is to pull the pull rod 33, and the pull rod 33 will drive the moving block 34 to move, and the moving block 34 will squeeze the spring 2 35 and at the same time drive the roller 32 to move away from the upper surface of the detection device cutting device body 1. After it is completely passed through, the pull rod 33 is loosened. At this time, the spring 2 35 will push the moving block 34 to move in the opposite direction through its own elasticity, and the roller 32 will also move in the opposite direction to clamp the connecting plate covering film 4. When the connecting plate covering film 4 is pulled, the roller 32 will roll to ensure the continuity of the pulling out of the connecting plate covering film 4. However, under the action of the spring 2 35, the pulled connecting plate covering film 4 will always be in a taut state to ensure the flatness of the coating. After the pulled connecting plate covering film 4 is used up, the cutting knife 36 can be pushed to cut it, thereby improving practicality.
