[0002] In the field of packaging printing, paperboard is a commonly used packaging material, and the ink drying treatment after printing is a key link to ensure packaging quality. At present, hot air drying is a widely used drying method. In order to prevent the ink from being scratched during drying, the existing drying equipment has to maintain a certain distance with the paperboard. However, the existence of this distance inevitably causes part of the heat to be lost when the hot air acts on the paperboard. Meanwhile, the thickness of the packaging paperboard varies greatly due to actual requirements, and when the frame supporting the paperboard is adjusted to a position close to the drying outlet position, it is difficult to flexibly and accurately adjust the position of the paperboard when replacing paperboards of different thicknesses, which is likely to cause the paperboard to be scratched by the drying equipment or other components. Such scratching not only damages the printed pattern on the surface of the paperboard, resulting in product scrap and increased production cost, but also affects the continuity of production and reduces production efficiency.
