[0017] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0018] Example: Through the personnel in this field, all electrical components in this case are connected to their corresponding power supplies through wires, and appropriate controllers should be selected according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between each electrical component is completed in the order of working. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and does not explain the electrical control.

[0019] See also Figure 1-3 In order to solve the problem that the operator needs to observe with the naked eye whether the position to be punched is aligned with the blanking part, which cannot guarantee the accuracy of the point and easily leads to the deviation of the punching position and inconvenience in use, this technical solution is designed. The detailed technical solution is as follows;

[0020] A leather punching machine comprises a base 1, two pairs of legs 2 are mounted on the base 1, punching structures are mounted on the two pairs of legs 2, and a supporting structure is mounted on the base 1;

[0021] Specifically, the punching structure includes two screw modules 3, which are installed on two pairs of legs 2, a horizontal plate 4 is installed between the two screw modules 3, a point laser 5 is installed at the center of the lower wall of the horizontal plate 4, a U-shaped frame 6 is installed on the movable end of the two screw modules 3, a first cylinder 7 is installed at the center of the lower wall of the U-shaped frame 6, a flange 8 is installed on the telescopic end of the first cylinder 7, a connecting plate 9 is movably installed on the lower wall of the flange 8, bolts 10 are inserted on the flange 8 and the connecting plate 9, a nut 11 is mounted on the bolt 10, a blanking and cutting sleeve 12 is installed on the lower wall of the connecting plate 9, an inner wall end of the blanking and cutting sleeve 12 is provided with a bevel 13, a material stripping assembly is installed inside the blanking and cutting sleeve 12, and a pressing assembly is installed on the lower wall of the U-shaped frame 6;

[0022] It should be noted that the punching and cutting sleeve 12 and the connecting plate 9 are fixed to the flange 8 on the telescopic end of the first cylinder 7 by bolts 10 and nuts 11 to achieve fixation and facilitate disassembly. When the device is in the non-punching state, the punching and cutting sleeve 12 is located on one side of the point laser 5, and when punching is working, the punching and cutting sleeve 12 and the point laser 5 are in a coaxial state. The leather is laid on the supporting structure. At this time, the laser line projected by the point laser 5 is displayed on the leather. The position to be punched is aligned with the laser line. Then the two screw modules 3 are controlled to work. The two screw modules 3 drive the U-shaped frame 6 to move and reset. At this time, the punching and cutting sleeve 12 and the point laser 5 are in a coaxial state, that is, the punching and cutting sleeve 12 is aligned with the position to be punched. By setting the point laser 5, the operator does not need to observe with the naked eye whether the position to be punched and the punching and cutting sleeve 12 are aligned, thereby ensuring the accuracy of the point, avoiding the deviation of the punching position, and facilitating use.

[0023] Specifically, the stripping assembly includes a spring 14, which is mounted on the inner top surface of the blanking and cutting sleeve 12, and a push block 15 is mounted on one end of the spring 14;

[0024] Specifically, the support structure includes a support cover 19, and a through hole 20 is provided on the upper wall of the support cover 19 corresponding to the point laser 5;

[0025] It should be noted that when punching, the leather is placed on the upper wall of the support cover 19, and the first cylinder 7 extends until the punching and cutting sleeve 12 contacts the leather. The end of the punching and cutting sleeve 12 is sharpened by the setting of the inclined surface 13, and the leather is cut until the punching and cutting sleeve 12 extends into the through hole 20. Then the first cylinder 7 contracts, and the punching and cutting sleeve 12 leaves the leather. If the cut waste enters the punching and cutting sleeve 12, the waste will compress the spring 14 through the push block 15 during the cutting process. When the punching and cutting sleeve 12 leaves the leather, the spring 14 resets, and the waste is pushed out of the punching and cutting sleeve 12 through the push block 15. Some of the waste will fall into the support cover 19 through the through hole 20.

[0026] Specifically, the pressing assembly includes two second cylinders 16, which are symmetrically installed on the lower wall of the U-shaped frame 6 with the first cylinder 7 as the center. The telescopic ends of the two second cylinders 16 are both equipped with connecting plates 17, and the connecting plates 17 are equipped with pressing rings 18.

[0027] It should be noted that after the position to be punched is aligned with the laser line, the two second cylinders 16 are extended to make the connecting plate 17 and the pressing ring 18 descend to press the leather, thereby fixing the leather;

[0028] As a preference, further, the inner diameter of the pressure ring 18 is larger than the outer diameters of the flange 8 and the connecting plate 9;

[0029] As a preferred embodiment, further, an L-shaped plate frame 21 is movably inserted into the support cover 19 to receive waste materials dropped from the through hole 20 .

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
