[0002] Steel wire is widely used in various industries. According to the actual working conditions of each industry, the processes required for steel wire production are also different. Therefore, there are various methods for steel wire surface treatment.

[0003] At present, in the tire bead wire industry, the processing process of steel wire is: wire rod → pretreatment → large drawing → medium drawing → copper plating. Before the copper plating process is wound, a layer of Kumarone solution (a xylene-based solvent) needs to be applied to the surface of the steel wire. The volatilization of Kumarone solution is harmful to the human body. Therefore, the Kumarone tank needs to be sealed and a secondary isolation room needs to be built.

[0004] The existing Kumarone coating process is to put the solvent in the tank, set a cover plate on it, open N holes on the cover plate (N steel wires), insert short cotton ropes, use the cotton ropes to absorb the solution, and the steel wire passes through the cotton ropes, and the surface of the steel wire will be coated with a uniform Kumarone solution coating by the cotton ropes. However, after long-term use, the steel wire and the cotton rope will rub and contact, and the cotton rope will be contaminated and worn. The cotton rope needs to be replaced manually regularly. Replacing 36 short cotton ropes at a time requires employees to stay in the secondary isolation room for a long time, which is not good for employee health. In addition, the replacement time is long, which affects the operation of the equipment.

[0005] Therefore, it is necessary to design a coating device for the steel wire surface so that the cotton rope can be replaced quickly and the cycle of replacing the cotton rope can be extended. Summary of the invention

10. A method for coating a steel wire surface, using the device for coating a steel wire surface as claimed in any one of claims 1 to 9, characterized in that The steps include: The steel wire (13) passes under the nylon pressure roller (10) on one side and enters the solution tank (2) through the wire hole (301). A whole cotton rope (401) is spirally wound on the winding roller (4). The lower half of the cotton rope (401) is immersed in the Kumarone solution in the solution tank (2). The Kumarone solution is absorbed by the cotton rope (401), thereby making the cotton rope (401) wet. The steel wire (13) passes through the gap between the cotton ropes (401) and is coated with a layer of Kumarone solution by the cotton ropes (401). After being coated with the Kumarone solution, the steel wire (13) passes out of the solution tank (2) through the wire hole (301) on the other side and passes under the nylon pressure roller (10) on one side. After a period of use, the contact point between the cotton rope (401) and the steel wire (13) is contaminated and blackened, and the servo explosion-proof motor (501) needs to be started. The servo explosion-proof motor (501) drives the winding roller (4) to rotate, so that the cotton rope (401) wound on the winding roller (4) rotates. Since the cotton rope (401) on the winding roller (4) is a whole spiral wound on the winding roller (4), and the pitch of the internal thread of the gear nut (7) is the same as the pitch of the spiral groove (404), when the winding roller (4) rotates, the gear nut (7) is locked by the lock tongue extended by the electromagnetic lock (6). Therefore, when the winding roller (4) rotates, the servo explosion-proof motor (501) and the entire winding roller (4) will move along the axial direction to ensure that the steel wire (13) does not deviate, and the contact point between the steel wire (13) and the cotton rope (401) becomes clean.
