[0021] Reference Figures 1 to 3 This application provides an engraving device for a printing roller 400, comprising: a base 100; a clamping mechanism including a first clamp 210 and a second clamp 220, the first clamp 210 and the second clamp 220 being respectively disposed at both ends of the base 100, the second clamp 220 being slidably disposed relative to the first clamp 210, the first clamp 210 and the second clamp 220 cooperating to clamp and fix the printing roller 400, the first clamp 210 and the second clamp 220 each including a rotating platform 230 and a clamping member 240, the rotating platform 230 being rotatably connected to the base 100, the clamping member 240 being disposed at the end of the rotating platform 230, the end of the clamping member 240 away from the rotating platform 230 being provided with a tapered fixed end 250, the fixed end 250 being engaged with the shaft hole 410 of the printing roller 400; and an engraving mechanism disposed on the base 100 and located above the clamping mechanism, the engraving mechanism being used to engrave the printing roller 400.

[0022] By providing a tapered fixed end 250 at the end of the clamping member 240 away from the rotary table 230, and utilizing the tapered structure of the fixed end 250 to connect with the shaft hole 410 of the printing roller 400, it can adapt to printing rollers 400 of different specifications. Compared with the three-jaw or four-jaw chuck structure of related technologies, it has wider adaptability, does not require changing the clamps, has a simple structure, is easy to operate, improves work efficiency, and reduces production costs. At the same time, since the fixed end 250 has a tapered structure, it can also achieve the positioning and centering of the printing roller 400, improve processing accuracy, and improve product quality.

[0023] Reference Figure 1 and Figure 2 Furthermore, the end of the clamping member 240 near the rotating platform 230 is designated as a mounting end 260, which has an inner hole 270. The rotating platform 230 passes through the inner hole 270 and is locked in place by the locking member 280. When installing the clamping member 240, the mounting end 260 is fitted onto the rotating platform 230, causing the rotating platform 230 to embed into the inner hole 270. Then, the clamping member 240 is locked onto the rotating platform 230 by the locking member 280, thus completing the installation of the clamping member and improving the stability and reliability of the connection. The locking member 280 is a locking bolt, and multiple sets of locking members 280 are arranged circumferentially around the axis of the mounting end 260. Furthermore, each set of locking members 280 has multiple members arranged along the axial direction of the mounting end 260. By adopting the above structure, the clamping member 240 can be connected to the rotary table 230 from multiple directions, further improving the stability of the connection and enhancing safety.

[0024] Reference Figure 1 In this embodiment, the base 100 is provided with a sliding part 110, the sliding direction of which is towards the first clamp 210. The second clamp 220 is provided with a slide table 290, which is connected to the sliding part 110. The sliding part 110 can be configured as an electric push rod structure, a gear and rack meshing structure, or a lead screw and nut structure. The first sliding part 110 drives the slide table 290 to move, thereby adjusting the position of the second clamp 220, thus adapting to printing rollers 400 of different lengths and expanding its applicability.

[0025] It is conceivable that a collection tray 120 is provided on the machine base 100 between the first clamp 210 and the second clamp 220, and the collection tray 120 is located below the slide table 290. By providing the collection tray 120, waste generated during engraving can be collected for subsequent centralized processing, making operation simple.

[0026] Reference Figure 1 and Figure 3In some embodiments of this application, the engraving mechanism includes a laser engraving head 310, which is disposed above the clamping mechanism and is used to engrave the printing roller 400. Further, the engraving mechanism also includes a moving part, which includes a first transverse moving group 320, a second transverse moving group 330, and a vertical moving group 340. The first transverse moving group 320 is disposed on the base 100 and is arranged along the left-right direction of the base 100. The second transverse moving group 330 is disposed on top of the first transverse moving group 320 and is arranged along the front-back direction of the base 100. The vertical moving group 340 is disposed on top of the second transverse moving group 330 and is provided with a mounting base 350. The laser engraving head 310 is rotatably mounted on the mounting base 350. The first transverse movement group 320 can drive the laser engraving head 310 to move back and forth, the second transverse movement group 330 can drive the laser engraving head 310 to move left and right, and the vertical movement group 340 can drive the laser engraving head 310 to move up and down. The laser engraving head 310 can also rotate. Thus, through the movement of the four axes, in conjunction with the rotation of the printing roller 400, the laser engraving head 310 can engrave on the printing roller 400 at various angles and directions, thereby engraving fine patterns, meeting production requirements, and greatly improving production efficiency.

[0027] As is easily understood, the laser engraving head 310 is connected to a laser generator 360, and the laser generator 360 is equipped with a controller 370, which is located on the outer wall of the mounting base 350. By fixing the controller 370 to the outer wall of the mounting base 350, it is easy to operate to adjust the laser intensity, etc., thereby improving work efficiency.

[0028] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
