[0013] The utility model provides a leather printing machine, which has the following beneficial effects compared with the existing technology: the shape of the punch in each mold part is different, and by controlling the operation of the servo motor, the driving end of the servo motor rotates, causing the rotating rod to rotate on the N-shaped frame, and the turntable thus drives multiple mold parts to rotate until the punch of the target pattern style is aligned with the operating table. If it is necessary to change the punch of a different pattern style, the servo motor can be controlled to work again. When embossing the pattern, the hydraulic cylinder extends to press the punch on the leather. When the pressure sensor detects that the pressure value reaches the set value, the punch has completed the printing of the leather. Then the hydraulic cylinder contracts, and the moving component works to align the punch with other positions to be printed. The operation is simple and easy to use.

DETAILED DESCRIPTION

[0018] 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.

[0019] 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.

[0020] See also Figure 1-3 In order to solve the problem that the embossing template of the embossing device is only provided with one pattern, when the pattern needs to be changed, the operator needs to manually disassemble and assemble the embossing template, which is inconvenient to operate, resulting in low work efficiency and affecting the leather processing efficiency, this technical solution is designed. The detailed technical solution is as follows;

[0021] A leather printing machine comprises an operating table 1, a door frame 2 is mounted on the operating table 1, a moving component is mounted on the door frame 2, and an embossing structure is mounted on the moving component;

[0022] It should be noted that the operating table 1 is used to spread the leather and is operated by a moving assembly mounted on the door frame 2, which is the movement of the stamping structure;

[0023] Specifically, the stamping structure includes a hydraulic cylinder 3, which is mounted on a mobile assembly. A pressure sensor 4 is mounted on the telescopic end of the hydraulic cylinder 3, and an n-shaped frame 5 is mounted on the pressure sensor 4. A rotating rod 6 is movably inserted on the n-shaped frame 5, and a servo motor 7 is mounted on one end of the rotating rod 6. A turntable 8 is fixedly mounted on the rotating rod 6, and a plurality of mold parts are mounted on the turntable 8 in a circular array with the rotating rod 6 as the center.

[0024] More specifically, each mold part includes an extension rod 9, which is mounted on the turntable 8. A mounting seat 10 is mounted on one end of the extension rod 9. A connecting block 11 is movably inserted on the mounting seat 10. A punch 12 is mounted on the connecting block 11. A threaded assembly is mounted on the mounting seat 10 and the connecting block 11.

[0025] It should be noted that the shape of the punch 12 in each mold part is different. When installing the punch 12, the connecting block 11 on the punch 12 is inserted into the mounting seat 10, and then the mounting seat 10 is connected to the connecting block 11 through a threaded assembly. By controlling the servo motor 7 to work, the driving end of the servo motor 7 rotates, causing the rotating rod 6 to rotate on the n-shaped frame 5, and the turntable 8 drives multiple mold parts to rotate until the punch 12 of the target pattern is aligned with the operating table 1. If it is necessary to change the punch 12 of a different pattern, the servo motor 7 is controlled to work again. When embossing the pattern, the hydraulic cylinder 3 extends to press the punch 12 on the leather. When the pressure sensor 4 detects that the pressure value reaches the set value, the punch 12 completes the printing of the leather. Then the hydraulic cylinder 3 contracts, and the moving assembly works to align the punch 12 with other positions to be printed. The operation is simple and easy to use.

[0026] More specifically, the moving assembly includes two longitudinal screw modules 13, which are mounted parallel to each other on the portal frame 2. A transverse screw module 14 is mounted on the moving ends of the two screw modules. The transverse screw module 14 and the two longitudinal screw modules 13 are mounted perpendicular to each other. The hydraulic cylinder 3 is mounted on the moving end of the transverse screw module 14.

[0027] It should be noted that, by working with the two longitudinal screw modules 13, the transverse screw module 14 and the stamping structure can be driven to move along the front-to-back direction of the device, and by working with the transverse screw module 14, the stamping structure can be driven to move along the left-right direction of the device;

[0028] As a preferred embodiment, the threaded assembly further includes a bolt 15, which is movable through the mounting base 10 and the connecting block 11, and a nut 16 is mounted on the bolt 15 for connecting and installing the mounting base 10 and the connecting block 11;

[0029] As a preference, further, a stabilizing frame 17 is installed between the servo motor 7 and the n-shaped frame 5 for fixing the servo motor 7;

[0030] As a preferred embodiment, further, the connecting block 11 and the male mold 12 are an integral structure;

[0031] Preferably, further, the connecting block 11 is a rectangular structure to prevent the connecting block 11 from rotating in the mounting seat 10 .

[0032] 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.
