Description

Technical Field

[0001] This utility model relates to the field of leather processing technology, and in particular to a leather punching device. Background Technology

[0002] Leather is animal hide that has undergone physical and chemical processing, such as hair removal and tanning, and is therefore less prone to decay. Leather is composed of natural protein fibers tightly woven in three-dimensional space. Its surface has a special grain layer, which has a natural grain and luster, and a comfortable feel. After the leather is produced, it needs to be cut into a fixed shape according to the product requirements before it can be used.

[0003] Currently, most fully automatic leather cutting machines are very expensive, so many small and medium-sized enterprises still cut leather into the desired shapes manually. However, manual cutting makes it difficult to ensure that the dimensions of the cut leather shapes are not deviated, which can easily affect the quality of the finished products. In addition, manual cutting is often slower and not conducive to efficient product output. Utility Model Content

[0004] Therefore, it is necessary to provide a leather punching device to address the problem that manual cutting is prone to deviations, which affects the quality of subsequent finished products and reduces production efficiency.

The side frames 20 are fixed on the worktable 10, and there are two side frames 20, which are spaced apart. The movable plate 30 is movably disposed between the two side frames 20. The front-to-back moving mechanism 40 is disposed on the side frames 20, and the movable plate 30 is connected to the front-to-back moving mechanism 40. The movable plate 30 moves in the front-to-back direction under the drive of the front-to-back moving mechanism 40. The punching moving mechanism 50 is disposed on the movable plate 30, and the punching die fixing plate 51 is disposed on the punching moving mechanism 50. The punching die fixing plate 51 moves in the vertical direction under the drive of the punching moving mechanism 50.

[0039] Please see Figure 2 The front and rear moving mechanism 40 includes a front and rear moving guide rail 41 and a front and rear moving slide 42. The front and rear moving guide rail 41 is fixedly connected to the side frame 20. The front and rear moving guide rail 41 corresponds one-to-one with the side frame 20. The front and rear moving slide 42 is slidably connected to the front and rear moving guide rail 41. The moving plate 30 is fixedly connected to the front and rear moving slide 42.

[0040] Please see Figure 2 The forward and backward moving mechanism 40 further includes a driving wheel 43, a driven wheel 44, a timing belt 45, and a forward and backward moving drive 46. The driving wheel 43 and the driven wheel 44 are spaced apart along the forward and backward direction on one of the side frames 20. The timing belt 45 is wound between the driving wheel 43 and the driven wheel 44, and a toothed block 47 is fixed on the timing belt 45. The forward and backward moving drive 46 is fixedly mounted on the side frame 20. The driving wheel 43 is drivingly connected to the forward and backward moving drive 46. The moving plate 30 is fixedly connected to the toothed block 47. This allows adjustment of the position of the moving plate 30, thereby adjusting the cutting position and effectively improving the applicability of the leather punching device 100.

[0041] Please see Figure 1The punching moving mechanism 50 includes a fixed plate 51, a punching drive cylinder 52, and a fixed frame 53. The fixed plate 51 is fixedly connected to the moving plate 30, the punching drive cylinder 52 is fixedly connected to the fixed plate 51, the fixed frame 53 is fixedly connected to the telescopic end of the punching drive cylinder 52, and the punching die fixed plate 51 is fixedly connected to the fixed frame 53. The punching die fixed plate 51 is provided with fixing holes for fixing the punching die 200, which allows the punching die 200 to be replaced according to actual needs, effectively improving the applicability of this leather punching device 100.

[0042] Please see Figure 1 The punching moving mechanism 50 also includes a guide rod 54, one end of which is fixedly connected to the punching die fixing plate 51, and the other end of which extends out of the moving plate 30. The guide rod 54 makes the punching die fixing plate 51 more stable during operation, effectively reducing the error caused by machine vibration during punching and effectively improving the cutting accuracy.

[0043] Please see Figure 1 The leather punching device 100 also includes a feeding mechanism 70, which is mounted on the worktable 10.

[0046] In this embodiment, the leather punching device 100 operates as follows: Before operation, the operator fixes the punching die 200 onto the punching die fixing plate 51. During operation, the operator places the leather to be processed onto the support plate 71. The controller controls the feeding driver 73 to move the support plate 71, carrying the leather, toward the worktable 10. The controller also controls the forward and backward movement driver 46 to adjust the position of the punching die 200. Then, the controller controls the punching drive cylinder 52 to move the punching die fixing plate 51 downward, completing the punching process of the leather by the punching die 200. Afterward, the punching drive cylinder 52 resets, and the controller controls the feeding driver 73 to deliver the punched leather.

[0047] The beneficial effects of this utility model are as follows: through the cooperation of the workbench 10, side frame 20, moving plate 30, front and rear moving mechanism 40, punching moving mechanism 50 and punching die fixing plate 51, semi-automatic leather punching can be achieved, eliminating the need for manual leather cutting, effectively improving leather cutting accuracy and cutting efficiency; at the same time, the structure of this leather punching device 100 is simpler than that of a fully automatic leather cutting machine, and the manufacturing cost is much lower than that of a fully automatic leather cutting machine, thereby effectively reducing production costs.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
