At this time, the trigger roller 330 contacts the printing plate roller. When the printing plate roller rotates, the convex plate on the printing plate roller contacts the trigger roller 330, thereby driving the trigger The roller 330 moves upward along the guide column 340, thereby driving the connecting plate 350 and the supporting plate 362 to move upward, and then driving the mounting plate 364 and the latch 365 to move upward, the latch 365 is separated from the grinding head 432, and the supporting plate 362 is above the rubber block 361, and then the shift plate 220 continues to move downward, and the guide frame 223 contacts the top of the shift rod 224, thereby driving the accommodating shell 410 to move along the guide rod 110 toward the direction close to the printing plate roller, so that the grinding head 432 contacts the surface of the printing plate roller. During the rotation of the printing plate roller, the grinding head 432 can grind the printing plate roller, and the gravity of the counterweight block 421 is transmitted to the top rod 431 through the liquid in the accommodating shell 410, thereby driving the grinding head 432 to contact the printing plate roller, and can ensure the stability of the grinding force of the grinding head 432 on the printing plate roller.
