[0029] Example 2

[0030] The difference between this embodiment and embodiment 1 is that, specifically, the engraving knife holder 4 also includes a second seat 44, which is located below the first seat 41 and is connected to the first seat 41 by a thread.

[0031] By adopting the above technical solution, it is convenient to assemble the slip ring 43, the first spring 47, the limiting pin 48 and the second spring 49.

[0032] Example 3

[0033] The difference between this embodiment and embodiment 1 is that, specifically, positioning blocks 6 corresponding to the four sides of the workbench 1 are connected to the top of the workbench 1. The positioning blocks 6 have an L-shaped structure and are provided with waist grooves. The positioning blocks 6 are connected to the workbench 1 by wing bolts.

[0034] The above technical solution is used to limit the position of the material to be carved.

[0035] The steps for automatically changing the engraving blade 5 according to this utility model are as follows:

[0036] (1) The carving walking mechanism 2 drives the carving knife holder 4 to the knife placement position on the carving knife box 7. The positioning of the specific carving knife 5 is determined by the displacement of the Y-direction moving screw module.

[0037] (2) The initial state of cylinder 71 is the extended state. The extension stroke is determined during equipment debugging. The carving walking mechanism 2 drives the carving knife seat 4 to descend to the set position. During this process, the protrusion 431 contacts the limiting plate 72, causing the slip ring 43 to move upward to the relief groove 432 to correspond with the limiting pin 48. Under the restoring force of the first spring 47, the limiting pin 48 retracts and separates from the limiting groove 53. The carving knife 5 slides down into the carving knife box 7 under the action of gravity.

[0038] (3) The carving walking mechanism 2 drives the carving knife seat 4 to rise to the safe position and move to the top of the carving knife to be replaced. Then it drives the carving knife seat 4 to fall to the set position. Then the cylinder 71 drives the limit plate 72 to move downward. At this time, the slip ring 43 slides downward under the restoring force of the second spring 49, pushing the limit pin 48 to extend into the mounting groove 45 to limit the carving knife 5.

[0039] (4) The carving walking mechanism 2 drives the carving knife holder 4 to rise to the safe position, and the cylinder 71 drives the limit plate 72 to reset upward, completing the automatic knife changing action.

[0040] In summary, this invention achieves a limiting connection between the carving knife 5 and the carving knife holder 4 by embedding the end of the limiting pin 48 into the limiting groove 53. The carving knife 5 can be easily disassembled and assembled by moving the slip ring 43 up and down. Thus, under the drive of the carving walking mechanism 2 and in cooperation with the carving knife box 7, the carving knife 5 can be replaced. Compared to manual replacement of the carving knife 5 in the prior art, this invention offers higher work efficiency and lower labor intensity. After the carving knife 5 and the carving knife holder 4 are assembled, the cylinder 71 drives the limiting plate 72 to descend, and the slip ring 43 moves downward under the restoring force of the second spring 49, pushing the limiting pin 48 out to limit the carving knife 5, thus providing conditions for automatic replacement of the carving knife 5.

[0041] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
