[0009] Furthermore, a transition roller is provided at the lower side of the cooling chamber.

[0010] The beneficial effect of the utility model is that: in the utility model, the copper foil is rolled up by the winding roller after passing through the feeding roller, the supporting roller, the rotating roller and the transition roller in sequence. The power mechanism is first connected to the side of the winding roller, and the power is given to make the winding roller rotate. During the rotation, the copper foil passes through the heating zone and the cooling zone in sequence to achieve annealing. Among them, the copper foil carried on the supporting roller between the left and right sides of the upper part of the bracket will be heated, wherein the upper part of the copper foil is heated by the upper heating tube, and the lower part is treated by the lower heating tube. The upper heating tube and the lower heating tube are both provided with multiple tubes to increase the heating power for heating treatment. At the same time, in order to improve the heating treatment effect, the upper part of the upper heating tube and the lower part of the lower heating tube are respectively provided with an upper fan and a lower fan for blowing air, so that the heating is more uniform. As the copper foil moves forward, the copper foil after heating treatment enters the cooling chamber for treatment.
