[0002] Paper products play an extremely important role in daily life, whether it is a disposable paper cup, paper tray, or paper box used for packaging and transportation, etc. are an indispensable part of people's lives. In order to ensure the quality of these products and extend their service life, it is necessary to properly dry the surface of the paper product during the production process. This step not only removes excess moisture, but also effectively prevents product deformation or mildew caused by excessive humidity.

[0003] However, the traditional paper product drying equipment usually uses a conveyor belt to send the objects to be dried into the drying box to complete the entire drying process. This method meets the basic needs to some extent, but also has obvious shortcomings - especially when the object to be dried is a paper box, as the bottom is in direct contact with the conveyor belt, making it difficult for this part to fully receive the effects of hot air, resulting in less than ideal drying results, and even partial drying. The situation is not dry.
