[0021] Furthermore, during operation, the carbon-based strip to be heated is wound on one of the winding mechanisms 2, and the carbon-based strip on the winding mechanism 2 is rolled into the upper heating body 5, and after being heated by the heated positive electrode 7, the graphite tension guide roller 8 and the heated negative electrode 6 in sequence, it is transported downward and wound by another winding mechanism 2.

[0022] An electrode fixing support plate 9 is provided at both ends of the heating negative electrode 6 and the heating positive electrode 7, the bottom end of the electrode fixing support plate 9 is fixed to the surface of the top plate 4, and both ends of the heating positive electrode 7, the heating negative electrode 6 and the graphite tension guide roller 8 are installed on the electrode fixing support plate 9, and a reinforcing plate 10 is connected between the edges of the two electrode fixing support plates 9 on both sides;

An insulating bushing 20 is sleeved on the outside of the conductive graphite guide roller 19, and the insulating bushing 20 is against the inner wall of the electrode fixing support plates 9 on both sides;

[0024] The insulating bushing 20 separates the electrode fixing support plate 9 from the inner graphite pressure roller 18 and the conductive graphite guide roller 19 and other components, providing an insulating effect to ensure safety. The water-cooled electrode 22 works to heat the graphite pressure roller 18 between the electrode fixing support plates 9 on both sides to obtain the required temperature.
