DETAILED DESCRIPTION

[0033] The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.

[0034] The present application embodiment discloses a leather cutting device. Figure 1 and Figure 2 A leather cutting device comprises a cutting table 1, a cutting assembly for cutting leather, and a fixing assembly for fixing the leather. The cutting assembly is installed on the cutting table 1, and after the leather is fixed by the fixing assembly, the leather can be cut.

[0035] For details, please refer to Figure 3 The fixing assembly includes a connecting rod 21 that is lifted and lowered on the cutting table 1, a first pressing plate 22 that is fixedly arranged at the bottom end of the connecting rod 21, a spring plate 23 that is rotatably arranged on the connecting rod 21, a second pressing plate 24 that is hinged at one end of the spring plate 23 that is away from the connecting rod 21, and a driving member for driving the connecting rod 21 to move up and down. There are four connecting rods 21, and they are distributed at the four corners of the cutting table 1. When the spring plate 23 is in a natural state, the second pressing plate 24 is located below the first pressing plate 22, so that when the connecting rod 21 moves downward, the second pressing plate 24 will first press on the leather. As the connecting rod 21 continues to move downward, the spring plate 23 will deform, so that the second pressing plate 24 moves in a direction away from the first pressing plate 22. When there are wrinkles on the leather or the bulges are not flat, the second pressing plate 24 presses against the leather and moves the second pressing plate 24 in a direction away from the first pressing plate 22, so that the leather can be stretched and flattened, so that the leather remains flat, thereby improving the cutting effect. When the connecting rod 21 moves to the point where both the first pressing plate 22 and the second pressing plate 24 are against the leather, the first pressing plate 22 and the second pressing plate 24 work together to fix the leather.

[0036] In order to adapt to the wrinkles in different directions on the leather, the position of the second pressing plate 24 can be adjusted by rotating the spring sheet 23, thereby adjusting the stretching and flattening direction of the second pressing plate 24. Figure 3, a rotating ring 25 is rotatably arranged on the connecting rod 21, the spring piece 23 and the rotating ring 25 are fixedly connected, and a positioning assembly for fixing the angle of the spring piece 23 is arranged on the rotating ring 25. The positioning assembly includes a positioning sleeve 31 slidably arranged on the rotating ring 25, a positioning tooth 32 fixedly arranged on the inner side of the positioning sleeve 31, a magnet 33 fixedly arranged on the top of the positioning sleeve 31, and an iron ring 34 fixedly arranged on the connecting rod 21. Among them, the circumferential surface of the connecting rod 21 is evenly distributed with positioning tooth grooves 211 matching the positioning teeth 32, and the positioning teeth 32 and the positioning tooth grooves 211 are aligned. By sliding the positioning sleeve 31 upward, the positioning teeth 32 and the positioning tooth grooves 211 can be clamped together, so that the rotating ring 25 cannot rotate. At this time, the magnet 33 and the iron ring 34 are adsorbed together to ensure the stability of the position of the positioning sleeve 31. When the rotating ring 25 needs to be rotated, the positioning sleeve 31 is pulled downward to disengage the positioning teeth 32 from the positioning tooth grooves 211 , and the magnet 33 and the iron ring 34 are separated, so that the rotating ring 25 can be rotated.

[0037] For further information, please refer to Figure 4 In order to facilitate the alignment of the positioning teeth 32 and the positioning tooth grooves 211 and facilitate the insertion of the positioning teeth 32 and the positioning tooth grooves 211, the positioning assembly also includes a positioning bead 35 slidably arranged on the connecting rod 21 and an elastic member for pushing the positioning bead 35 out of the connecting rod 21. The type of the elastic member is not specifically limited. In this embodiment, the elastic member is a spring 36, and the two ends of the spring 36 are respectively against the connecting rod 21 and the rotating ring 25. The inner side of the rotating ring 25 is evenly distributed with positioning ball grooves 251 matching the positioning bead 35. When the positioning bead 35 is engaged in the positioning ball grooves 251, the positioning teeth 32 and the positioning tooth grooves 211 are aligned, so that the positioning teeth 32 can be directly inserted into the positioning tooth grooves 211. When the rotating ring 25 is rotated, the positioning bead 35 will be pressed into the connecting rod 21. When the positioning bead 35 and the positioning ball groove 251 are aligned, the positioning bead 35 will be engaged in the positioning ball groove 251 under the action of the spring 36, thereby playing a positioning role.

[0038] Please refer to Figure 1 and Figure 2 The driving member is a cylinder 26 fixedly arranged on the cutting table 1, and the piston rod of the cylinder 26 is fixedly connected to the connecting rod 21. The cylinder 26 can drive the connecting rod 21 to move up and down, thereby fixing the leather.

[0039] Please refer to Figure 3 A gasket 27 is fixedly provided on the bottom surface of the first pressing plate 22 and the second pressing plate 24. The gasket 27 is made of rubber material and can avoid scratching the leather.

[0040] Please refer to Figure 1 and Figure 2The cutting assembly includes a first electric slide rail 41 fixedly arranged on both sides of the cutting table 1, a first slider 42 slidably arranged on the first electric slide rail 41, a second electric slide rail 43 fixedly arranged between the two first sliders 42, a second slider 44 slidably arranged on the second electric slide rail 43, and a laser cutter 45 fixedly arranged on the second slider 44. Among them, the moving track of the first slider 42 and the moving track of the second slider 44 are perpendicular to each other. The second electric slide rail 43 can be driven to move by the first electric slide rail 41 and the first slider 42, and the laser cutter 45 can be driven to move by the second electric slide rail 43 and the second slider 44, so that the laser cutter 45 can cut the leather.

[0041] The implementation principle of the embodiment of the present application is as follows: the leather is placed on the cutting table 1, and the angle position of the spring piece 23 is adjusted according to the wrinkles and ridges on the leather. The positioning sleeve 31 is pulled downward, and the rotating ring 25 is rotated to adjust the position of the spring piece 23. After the adjustment is completed, the positioning sleeve 31 is pushed upward so that the positioning teeth 32 and the positioning tooth grooves 211 are plugged in, and the magnet 33 and the iron ring 34 are attracted to each other.

[0042] The cylinder 26 is started, so that the second pressing plate 24 first presses against the leather to stretch and flatten the leather, and as the connecting rod 21 continues to move, the first pressing plate 22 also presses against the leather to fix the leather. Then the first electric slide rail 41 and the second electric slide rail 43 are started to adjust the position of the laser cutting machine 45 to achieve leather cutting.

[0043] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
