Compared with the prior art, the invention has the beneficial effects that:

firstly, the principle of preventing the yellow edge is realized by the design and the cooperation of a yellow edge prevention mechanism, a space change assembly and a drying cylinder body;

in the design of the drying cylinder body, cooling water is concentrated at two ends of the drying cylinder body through the drainage grooves, and heat transfer between the two ends of the drying cylinder body and steam can be prevented through condensed water, so that the temperature at the two ends of the drying cylinder body is lower than that at the middle part of the drying cylinder body, and the condition that yellow edges of paper appear can be prevented;

when the space change assembly works, a large amount of gas is filled into the elastic interlayer and the drying cylinder body, so that the steam content at the two ends of the drying cylinder body is reduced, the temperature at the two ends of the drying cylinder body is lower than the middle part of the drying cylinder body, and the occurrence of yellow edges can be avoided.
