Some enameled wires need to wind plastic wires outside the stranded wires which are subjected to stranding operation, and then the enameled wires are sent into a baking furnace to be baked, so that outer-layer plastic is softened and bonded, and an insulating protective layer is formed outside the stranded wires. Therefore, the conducting wire which is wound is often required to be placed on a pay-off rack, enter a baking furnace at a constant speed and receive high-temperature baking. However, the existing pay-off rack is often used to arrange a brake disc on the pay-off shaft, and simultaneously, a brake belt is tightly attached to the outer peripheral surface of the brake disc, and the tension adjusting device is matched to pay off the brake disc at a constant speed as much as possible. However, the wire drum can only rotate when the traction force of the traction wire is greater than the friction force between the brake belt and the brake disc, and the wire has certain tension, so that the wire drum is difficult to control to pay off at a constant speed. When the pay-off rate of the pay-off rack is uneven, the tension and pulling state of the wire are difficult to keep consistent, so that the baking time of each section of the wire and the distance between each section of the wire and a heat source are difficult to keep consistent, the color depth and the thickness of a protective layer of the wire are different, and the product phase is influenced.
