[0014] 1, cathode roller main body;2, shaft;3, insulating coating;4, adhesive tape;5, anode groove. DETAILED DESCRIPTION

[0015] In order to make the purpose, technical scheme and advantage of the utility model embodiment more clear, the technical scheme in the utility model embodiment will be clearly and completely described below in combination with the drawings in the utility model embodiment, obviously, the described embodiment is a part of the embodiment of the utility model, rather than all the embodiment. The components of the utility model embodiment described and shown in the drawing here can be arranged and designed in various different configurations.

[0016] Therefore, the following detailed description of the embodiment of the utility model provided in the drawing is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model. Based on the embodiment in the utility model, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the utility model.

[0017] It should be noted that: similar signs and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

This isolates the influence of the anodic electric field at the shielding point on the electroplating area, thus determining the effective electroplating width of the cathode roller. After the electroplating of this batch of products is completed, if it is necessary to change the electroplating width, the adhesive tape 4 can be removed, and the insulating coating 3 can be ground clean with a grinding wheel. Then, a new insulating coating 3 can be applied as needed, and another ring of adhesive tape 4 can be placed. This achieves the purpose of adjustable electroplating width of the cathode roller without replacing the cathode roller, reducing costs.
