During the electroplating operation, the plate roller to be electroplated is placed in the electrolyte containing copper ions through the device, and the first gear 82 and the second gear 83 are meshed and connected with the gears on the electroplating tank. The driving motor drives the gears on the electroplating tank to rotate, and then drives the rotating shaft 81 to rotate through the first gear 82 and the second gear 83. The rotation of the rotating shaft 81 drives the first conductive shaft 3 and the copper bar 5 to rotate, thereby realizing the rotation of the plate roller. The plate roller is connected to the electrode through the copper bar 5, the first conductive rotating shaft 3 and the second conductive rotating shaft 4 in turn to realize electrical conduction, so that copper ions are deposited on the surface of the plate roller to form a uniform copper layer.

The rotating shaft 81 is installed at the end of the first conductive rotating shaft 3, and the first gear 82 and the second gear 83 are installed on the rotating shaft 81.

The plate roller rotates, and the plate roller is connected to the electrode through the copper rod 5, the first conductive shaft 3 and the second conductive shaft 4 in turn to conduct electricity, so that copper ions are deposited on the surface of the plate roller to form a uniform copper layer. During the copper plating process, the elastic insulating retaining ring 6 prevents the end faces of the plate roller from directly contacting the plating solution in the electroplating tank. The end faces of the plate roller are insulated from the plating solution to prevent the edge of the plate roller from being burned, thereby improving the qualified rate of the electroplating of the plate roller. The clamping piece 7 can clamp the plate rollers of different diameters. There is no need to replace the hangers of different specifications during the processing, which saves time and effort, reduces the labor intensity of the staff, and improves the work efficiency of the copper plating of the plate roller.
