s2, winding the copper wire (21) on the outer walls of two rotating discs (16) in an S shape, extending out of the discharge pipe (6), starting the heating pipe (15) to heat the copper wire (21), starting the first motor (19), starting the output shaft of the first motor (19) to rotate and drive the rotating discs (16) to rotate, and driving the heating pipe (15) wound on the outer walls of the rotating discs (16) to move forwards through the rotating discs (16);
s3, a copper wire (21) passing through a discharge pipe (6) extends into a cooling water tank (8), cooling water is poured into the cooling water tank (8), the copper wire (21) bypasses the bottom of a first rotating roller (22) and bypasses the top of a cleaning cloth (23), the copper wire extends into a drying box (10) through a feed port (25), a second motor (36) is started, an output shaft of the second motor (36) drives a rotating shaft (35) to rotate, the rotating shaft (35) drives a second rotating roller (34) to rotate, the second rotating roller (34) drives the cleaning cloth (23) to rotate, the cleaning cloth (23) is in contact with the copper wire (21), and most of cooling water remained on the surface of the copper wire (21) is wiped;
s4, the copper wire (21) extends into the drying box (10) from the feeding hole (25) and extends out from the discharging hole (31), the drying lamp (24) is started, and the drying lamp (24) dries the cooling water and the antioxidant liquid on the surface of the copper wire (21);
s5, pouring the antioxidant liquid into the antioxidant water tank (12), starting the water pump (11), discharging the antioxidant liquid in the antioxidant water tank (12) into the water outlet pipe (30) through the water inlet pipe (28) by the water pump (11), discharging the antioxidant liquid into the water storage box (32) from the water outlet pipe (30), finally discharging the antioxidant liquid to the surface of the copper wire (21) from the inside of the spray head (33), reacting with the copper wire (21), enabling the reacted precipitate and the antioxidant liquid to enter the antioxidant water tank (12) from the water outlet (26), enabling the precipitate to be left at the top of the filter screen (27) and not to pass through, and ensuring that the antioxidant liquid can be recycled.
