[0002] Thermal paper, also known as thermal fax paper, thermal recording paper, or thermal copy paper, is a type of processed paper. Its manufacturing process involves coating high-quality base paper with a thermal coating. During production, the coated thermal paper needs to be dried.

[0003] A drying apparatus for producing thermal paper, disclosed in publication number CN213914667U, utilizes a method where a rotating motor drives a rotating mounting column within a drying chamber during the drying process. This rotation of the mounting column, in turn, causes a paper fixing device to rotate within the drying chamber, ensuring uniform drying of the thermal paper on the fixing device. This allows for even drying of both sides of the thermal paper.

[0004] However, the drying device for thermal paper production has the following disadvantages: it is not convenient to purify the harmful gases generated during the drying of thermal paper, and the coated adhesive will generate harmful gases in the drying chamber, which will affect the working environment and personnel health.
