[0028] Embodiment 2:

[0029] See also Figure 1-4 A pre-printing plate roller with a protective function comprises a base 1, a protective cover 4 is fixedly connected to the surface and the back of a chassis 301, which can protect the pre-printing plate roller 203 during processing and increase its service life. Both sides of the top of the inner cavity of the chassis 301 are fixedly connected with slide rails 5, and a slider 6 is slidably connected to the surface of the slide rail 5. The bottom of the slider 6 is fixedly connected to a threaded sleeve 304, which can limit and guide the threaded sleeve 304 and increase the stability of the threaded sleeve 304 when the threaded rod 303 drives the threaded sleeve 304 to move left and right.

[0032] When it is found that the pattern or text on the surface of the pre-print roller 203 is unclear, the dual-axis motor 302 is started to drive the two threaded rods 303 to rotate. Due to the design of the positive and negative threads on the surfaces of the two threaded rods 303, the two threaded rods 303 can drive the two threaded sleeves 304 to move away from each other, and then drive the fixed plate 305 to move away from each other, and finally drive the mounting block 306 to move out of the mounting groove 307, so that the pre-print roller 203 can be quickly disassembled, and then the new pre-print roller 203 can be installed in place. At this time, the dual-axis motor 302 is started again to rotate in the opposite direction, which can drive the mounting block 306 to enter the mounting groove 307 and quickly install the pre-print roller 203, thereby realizing quick disassembly and assembly of the pre-print roller 203 and improving convenience.

[0033] In summary: this pre-print roller with a protective function can perform printing operations by setting up a processing component 2, wherein the first electric push rod 202 can push the pre-print roller 203 to adjust the height, so that it can cooperate with the guide roller 204 to achieve rapid printing operations, and the installation component 3 can be set to facilitate the disassembly and assembly of the pre-print roller 203, wherein the dual-axis motor 302, the threaded rod 303 and the threaded sleeve 304 can be set to drive the two fixed plates 305 to adjust the spacing, and then the installation block 306 can be easily inserted into the installation groove 307, thereby achieving rapid disassembly and assembly of the pre-print roller 203.
