[0002] In the process of processing the printing plate roller, the copper surface of the plate roller needs to be polished and roughened, otherwise knife lines and ink lines will easily appear on the printed product when the plate roller is printed. The existing polishing and roughening method is to install the plate roller on the wet polishing machine lathe to rotate the plate roller. Figure 5 and Figure 6 The scouring pad on the polishing device shown presses the surface of the plate roller, and the polishing device moves left and right along the axis of the plate roller for polishing. In order to ensure the polishing effect, the polishing sheet needs to be replaced regularly.

The polishing sheet needs to be torn off and re-pasted, otherwise it will affect the polishing effect and reduce work efficiency. Therefore, it is necessary to invent a polishing sheet pasting device. Utility Model Content

At this time, the shaft of the third motor 130 and the second T-shaped shaft sleeve 140 are both facing upward. After the old scouring pad is torn off manually or using other equipment, the first motor 10 is controlled by the operation button to drive the workbench 40 and the third motor 130 to move to the right side of the machine tool. When the second T-shaped shaft sleeve 140 is located directly below the pasting hole 101, the second cylinder 8 drives The pasting device descends to a certain height, at which time the first cylinder 5 pushes the push rod to press down the stacked scouring pads, the elastic support sheet 2 is deformed by force, and after the bottom layer of scouring pads is pasted to the Velcro 150, the second cylinder 8 drives the pasting device to rise to a certain height, and the bottom layer of scouring pads is separated from the elastic support sheet 2, and the pasting of new scouring pads is completed; then the first cylinder 5 drives the pressure plate 6 to move upward, the elastic support sheet 2 rebounds, and the second layer of scouring pads from bottom to top is limited by the lifting part 203 and will not fall from the pasting hole 101. Finally, the first motor 10 drives the workbench 40 back to the position to continue grinding the plate roller.
