The utility model discloses a copper wire drawing device, it is including the pay -off, wire drawing diaphragm capsule, powder remover and the take -up that set gradually. Pay -off includes bracing piece, wire wheel and unwrapping wire roller. The bracing piece includes vertical section and horizontal segment, and the wire wheel sets up on the horizontal segment, and the unwrapping wire roller sets up in wire wheel below. Powder remover includes the support and whitewashes the roller set, whitewashes the roller set and articulate on the support. Take -up includes that line arranging device constructs and winding mechanism, and line arranging device constructs the connection on winding mechanism. Winding mechanism includes frame, second motor, I -shaped wheel carrier and reducing gear box, and the I -shaped wheel carrier is installed in the frame through the pivot. The second motor is fixed in the frame, and the reducing gear box is connected to the second motor, and the reducing gear box passes through the pivot of second coupling joint. The wire drawing powder on the copper wire is clear away through powder remover to the present case after the wire drawing, carry out winding displacement rolling, the copper wire coil of wire that can be compacted closely knitly through take -up again.
