After the heat of the aluminum rods is transferred to the aluminum rod heating conveying roller, the heat can be dissipated through the gap between the heat dissipation cylinder 300 and the center shaft 100, and at the same time, the heat transfer path distance of the aluminum rods and the two ends of the center shaft 100 is increased to avoid direct heat transfer to the center shaft 100 to cause the temperature of the two ends of the center shaft 100 to be too high.
