Post-treating machine for electrolytic copper foil

The utility model discloses a post-treating machine for an electrolytic copper foil. The post-treating machine comprises a post-treating machine array, wherein a diversion conducting roller which is connected in parallel with a first conducting roller is arranged in front of the first conducting roller and behind a second conducting roller of the post-treating machine array. Due to the arrangement of the diversion conducting roller which is connected in parallel with the first conducting roller and is arranged in front of the first conducting roller and behind the second conducting roller of the post-treating machine for the electrolytic copper foil, the current density of the first conducting roller is lowered, the problem of easily-caused electrical erosion of the first conducting roller is solved, the probability of the formation of local copper plating points on the roller surface of the conducting rollers is greatly lowered, the roller surface is kept be flat, the adverse effect on the electrolytic coppe
