Then, the plate is moved from bottom to top and passed between the two clamping components 55. The arc-shaped setting at the bottom end of the clamping plate 551 can play a guiding role and can adapt to plates of different thicknesses. When the plate passes between the two clamping components 55, the plate will squeeze and push the clamping plate 551, so that the clamping plate 551 slides inside the rectangular groove 554. When the clamping plate 551 moves, it will squeeze the compression spring 552, so that the compression spring 552 is deformed.

Since the outer side of the limit block 543 is in contact with the inner side of the sliding limit groove 33, the cutting assembly 54 can be ensured to move parallel to the plate, and the blade 542 cuts the plate, changes the length of the plate, and makes the edge of the plate flush. Then, according to the width of the plate, the corresponding clamping plate 44 is rotated downward so that the clamping head 42 is clamped into the clamping groove 45. At this time, the anti-slip pressure strip 46 will squeeze the plate, so that the plate is in contact with the roller shell body 31 to prevent the plate from shaking. Then, the plate is attached to the plate roller 2, and the anti-slip pressure strip 46 is separated from the plate. The plate roller 2 is rotated, and the plate can be pasted around the plate roller 2 for a week. This ensures that the plate can be accurately and firmly attached to the plate roller 2, which is convenient for subsequent printing work.
