Conductor surface tumbling mechanism and surface treatment device

The invention relates to the field of conductor processing devices, in particular to a conductor surface tumbling mechanism and a surface processing device. A conductor surface tumbling mechanism comprises two sets of rolling wheels which are oppositely arranged, at least one set of rolling wheels is a driving wheel, at least one set of rolling wheels is movably arranged in the direction close to and away from the other set of rolling wheels, the rotation directions of the two sets of rolling wheels are consistent, and the axes of the two sets of rolling wheels are arranged in parallel at intervals. A channel for a conductor to be tumbled to pass through is formed between the two groups of rolling wheels, one group of rolling wheels in the two groups of rolling wheels inclines clockwise on the axis extending around the pressure applying direction, the other group of rolling wheels in the two groups of rolling wheels inclines anticlockwise on the axis extending around the pressure applying direction, and the i
