[0001] The present application relates to the technical field of wire drawing machines, in particular to a wire dirt removing device and a wire drawing machine provided with the same. BACKGROUND

[0002] The bare copper wire produced by the wire drawing machine is drawn into a preset diameter copper wire through a die. In order to reduce the friction during drawing, the wire drawing lubricant is sprayed at the die. The copper wire has residual copper powder and wire drawing liquid on the surface after passing through the last die. These residues will cause oxidation of the bare wire, affect the downstream coating of insulating paint, and thus cause quality problems.

[0003] Due to the small size of the finished wire of the small wire drawing machine, the equipment size is limited, and it does not have a cleaning function for the wire. At present, the wire surface is wiped by placing a felt under the wire at the wire outlet die, but only one side of the wire in contact with the felt can be wiped, and the other side cannot be wiped. In order to make the felt fully contact with the wire, thick felt is needed, which will increase the friction between the felt and the wire, and also cause the wire to be thinned. After the felt is used for a period of time, copper powder and oil stains accumulate at the position where the wire passes, and more copper powder and oil stains are adhered to the wire when it passes.

[0028] In order to make the purpose, technical solutions and advantages of the present application more clear, the technical solutions of the present application will be described in detail below. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of the present application.

[0029] Referring to Figures 1-2For the structure of wiping the wire with felt in the prior art, the last wire drawing die on the wire drawing equipment is embedded on the box body of the wire collecting box, and there is an annular iron die fixing part 1 around the wire drawing die in the wire collecting box, which is fixed on the box body of the wire collecting box by screws, and a half-cylinder-shaped felt holder 6 is fixed on the lower half of the die fixing part 1, the arc-shaped part is downward, and the flat part is upward, and the flat part has a cuboid-shaped groove for placing the wiping felt 7, and the wire 2 passes through the wiping felt, and the contact part of the wire is wiped by the wiping felt. The wiping felt 7 is placed under the wire at the wire drawing die port to wipe the surface of the wire, but only one side of the wire in contact with the felt can be wiped, and the other side cannot be wiped. In order to make the felt fully contact with the wire, thick felt needs to be used, which will increase the friction between the felt and the wire, and also cause the wire to be drawn thin. Based on this, the present application provides a wire dirt removal device, which has a simple structure and can better remove copper powder and oil stains on the surface of the wire. The specific introduction is as follows:
