An anti-oxidation solution is provided in the anti-oxidation box 41. The anti-oxidation box 41 is located below one end of the conveyor belt 25, which can receive the drawn metal plate transported from the conveyor belt 25, so that the metal plate can be directly anti-oxidized after the wire drawing operation is completed, which greatly improves the efficiency of the metal plate wire drawing anti-oxidation operation and reduces time waste. Two groups of electric push rods 42 are provided in the anti-oxidation box 41, and the mounting end of the electric push rod 42 is installed corresponding to the bottom wall of the inner cavity of the anti-oxidation box 41.

[0022] In this embodiment, the operator places the metal plate that needs to be drawn above the conveyor belt 25, and then the operator energizes the conveying motor 22.

When the metal plate is conveyed to the position of the pressure roller 5, under the action of continuous conveying, the metal plate pushes the pressure roller 5 upward, so that the pressure roller 5 conveys the metal plate through the conveyor belt 25 under the pressure. When the metal plate is conveyed to the bottom of the wire drawing roller 310, the wire drawing operation begins. The wire-drawn metal plate naturally falls into the anti-oxidation box 41 after continuous conveying, so that the wire-drawn metal plate is completely immersed in the antioxidant solution in the anti-oxidation box 41. When the immersion is completed, the operator energizes and starts the electric push rod 42. The electric push rod 42 drives the supporting plate 43 to move upward, so that the supporting plate 43 drives the metal plate carried above to separate from the antioxidant solution, and then the anti-oxidation solution on the metal plate is quickly dripped back into the anti-oxidation box 41 through the arc-shaped supporting plate 43 and multiple groups of leakage holes 44, thereby completing the wire drawing anti-oxidation treatment of the metal plate.

[0023] The above specific embodiment is only a preferred embodiment of the present invention.
