A second synchronous wheel 324 is fixedly installed on the outside of the heating roller 323 near the front end. A first synchronous belt 325 is installed for transmission between the first synchronous wheel 322 and the second synchronous wheel 324. Nine heating rollers 323 are provided, and a second synchronous belt 326 is installed between two adjacent heating rollers 323 through synchronous wheel transmission. A spiral plate 327 is fixedly installed inside the heating roller 323 to increase the flow time of the heating medium inside the heating roller 323, improve the heating efficiency, and facilitate the transportation of paper and drying at the same time.
