The deplating cathode 21 is at least one of titanium and stainless steel which are flaky and net-shaped and can be used as electroplating cathode materials.

In the deplating loop, the electroplated metal on the surface of the conductive roller 3 is electrolyzed and reduced again into metal ions which return to the electrolyte and move towards the deplating cathode 21, but due to the obstruction of the diaphragm 23, the metal ions can only stay in the electroplating solution outside the deplating box 22 and then are electroplated on the plated object 7 again by the electroplating loop, and the metal ions electrolytically separated from the surface of the conductive roller 3 are recycled while the electroplating and deplating are realized, so that the problem of frequent maintenance is solved, wherein the frequent maintenance comprises replacing the deplating cathode 21, because if only the electroplated metal on the surface of the conductive roller 3 is transferred onto the deplating cathode 21, the deplating cathode 21 needs to be replaced at every certain time to ensure the deplating effect.

In this embodiment, the deplating cathode 21 is installed on the inner bottom surface of the accommodating cavity 24 and is opposite to the diaphragm 23.

the deplating components 2 correspond to the conductive rollers 3 one by one, and the deplating components 2 are arranged on one side of each conductive roller 3, which is far away from the plated object 7; the positive electrode of the deplating power supply U2 is connected with the conductive roller 3, the negative electrode of the deplating power supply U2 is connected with the deplating cathode 21, one side surface of the conductive roller 3 close to the deplating cathode 21 and the deplating cathode 21 form a deplating loop, the deplating loop electrolytically reduces the plated metal on the conductive roller 3 into metal ions which return to the electrolyte and move towards the deplating cathode 21, but due to the arrangement of the diaphragm 23, the metal ions cannot pass through the diaphragm 23, and then the metal ions are electroplated on the plated object 7 by the electroplating loop, so that the metal ions are recycled.
