Since the flowing direction of the hot air in the ventilation groove 17 is opposite to the conveying direction of the conveyor belt 4, a large temperature difference can be maintained at the contact area between the hot air and the conveyor belt 4, thereby further improving the heating efficiency and enabling the conveyor belt 4 to be heated to a higher temperature, and further improving the preheating effect.
