Electrolytic copper foil tensioning device

Abstract

The utility model provides an electrolytic copper foil tensioning device, and belongs to the technical field of copper foil processing. A fixing ring; the rotating ring is arranged on the outer side of the fixed ring; the tensioning assemblies are arranged, each tensioning assembly comprises a sliding groove, a tensioning block, a connecting rod and a clamping groove, the sliding grooves are formed in the circumferential surface of the fixing ring, the tensioning blocks are slidably connected into the sliding grooves, and the connecting rods are rotatably connected to the circumferential inner wall of the rotating ring and one side ends of the tensioning blocks through rotating shafts; the clamping groove is formed in one side end of the tensioning block, the tensioning force on the copper foil is guaranteed through stretching, all the positions of the copper foil are evenly stressed, and it is guaranteed that the copper foil does not wrinkle after being tensioned.
