[0041] The working principle of the leather punching and cutting device 100 in this embodiment is as follows: During operation, the leather roll to be processed is placed outside the unwinding roller 22, and the end of the leather to be processed extends into the gap between the feeding roller 32 and the upper pressure roller 34. The unwinding driver 23 drives the unwinding roller 22 to rotate. During this process, the feeding roller 32 rotates under the drive of the feeding driver 33 so that the leather to be processed is fed into the punching mechanism 40. Under the drive of the punching driver 44, the upper punching die 42 moves downward and closes with the lower punching die 43 to perform the punching step on the leather to be processed. Under the drive of the feeding driver 33, the leather continues to be conveyed to a suitable length. The cutting driver 55 drives the upper cutting seat 53 to move downward and closes with the lower cutting seat 54 to cut the leather that has completed the punching process. The finished product falls onto the unloading conveyor belt 63. With the cooperation of the unloading driver 64, the active roller 61, the passive roller 62 and the transmission belt 65, the finished product is sent out to complete the unloading.

[0042] The beneficial effects of this utility model are as follows: the workbench 10, leather supply mechanism 20, feeding mechanism 30, punching mechanism 40, cutting mechanism 50, and unloading mechanism 60 can automatically complete the feeding, punching, cutting, and unloading processes, achieving a high degree of automation, effectively improving punching quality and production efficiency; no manual intervention is required throughout the production process, effectively reducing the probability of safety accidents and improving the safety performance of the leather punching and cutting device 100; at the same time, there are two punching mechanisms 40, which are arranged adjacent to each other, and the leather supply mechanism 20, the feeding mechanism 30, the punching mechanism 40, and the cutting mechanism 50 correspond one-to-one, which can further improve production efficiency.

[0043] 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.

[0044] 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. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
