BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conductor roll cleaning device, and more particularly, to a cleaning device for a conductor roll for electroplating of a carousel (Consumable Anode Radial One-Side Electroplating Line) type.

An electroplating conductor roll refers to a roll that sends a negative voltage of direct current power to the roll band of the roll, and sends a positive voltage to the anode to allow the solution to electroplate the strip by electrical action. In particular, urethane seals are provided at the edges of the strip to prevent plating around due to the current-carrying hysterello band, and the band is slightly higher than urethane to prevent arcing. It should also not be high enough to leave marks on the strip, and the band should not be plated.

Electroplated steel sheet has excellent corrosion resistance, paintability and weldability, and is used as interior finishing materials for automobiles, construction materials, and automobile exterior panels. Such coated steel sheets produce band marks and arc spots depending on the condition of the conductor roll during the manufacturing process. Step marks are generated, which is a cause of product defects.

The second transfer part includes a second drive motor 111 and also includes a connecting shaft 201 connected to the second drive motor 111. The connecting shaft 201 is connected to the rotating shaft 205 supporting the upper side of the polishing belt 106, and serves to transmit the rotation to the rotating shaft 205.

Preferably, the rotating shaft 205 and the connecting shaft 201 are connected to each other through the universal joint 117. The universal joint 117 is used to transmit rotational power when the two axes do not have a central axis coincident with each other and are shifted at a predetermined angle. The reason for using the universal joint 117 as described above is to allow the polishing belt 106 to transmit the rotational force from the second driving motor without any problem even when the rotation shaft angle is slightly misaligned due to the movement of the polishing block 105. .                     

The cylindrical boss 129 is inserted into the rotation shaft 205. The boss 129 has a guide bar (not shown) is formed to protrude so as to rotate like the rotating shaft 205 and inserted into the rotating shaft, and the same guide groove may be formed in the rotating shaft 205. have.
