The drying box 1 is provided with trays 5 at intervals, and the top of the drying box 1 is provided with a bellows 6. The middle of the top of the bellows 6 is provided with an air inlet 60 connected to the air duct of the fan 4, and the bellows 6 is provided with a guide component. The heated air can be evenly dispersed and transported so that the printed matter can be heated evenly. A diversion structure is arranged between the bellows 6 and the inner wall of the drying box 1. The diversion structure includes an air duct 7 and a diversion plate 71. Air outlets 61 are respectively provided on the left and right sides of the bottom of the bellows 6. The two air outlets 61 are respectively connected to the air duct 7, and the bellows 6 is communicated with the air duct 7. Air ducts 70 are spaced apart on one side of the air duct 7 close to the tray 5. Diversion plates 71 corresponding to the air duct 70 are spaced apart on the inner side of the air duct 7. The hot air can be evenly dispersed to the printed matter placed on the tray 5 through the air duct 70, so that the printed matter can be heated evenly in an all-round way, thereby avoiding the phenomenon of uneven local heating of the printed matter.

[0023] For further information, see Figure 2-Figure 5 As shown, the guide assembly includes a guide plate 8, a cylinder 9, a rack 10 and a gear 12. Five guide plates 8 are rotatably arranged in the middle of the bottom of the bellows 6 through a rotating shaft. A cylinder 9 is arranged on the right front side of the bellows 6. The end of the telescopic rod of the cylinder 9 is connected to the rack 10. A gear 12 is respectively sleeved on the rotating shaft on the front side of each guide plate 8, and the gear 12 is meshed with the rack 10. The cylinder 9 is controlled to drive the rack 10 to move back and forth, and then the gear 12 can drive the guide plate 8 thereon to perform reciprocating flipping and swinging, so as to achieve the purpose of dispersing and guiding the hot air.

[0024] For further information, see Figure 2 , Figure 3 and Figure 6 As shown, the width of the air guide port 70 increases gradually from small to large from top to bottom, so that the hot air can be evenly diverted and discharged.

[0025] For further information, see Figure 3 and Figure 6 As shown, the diverter plate 71 is set at an inclined angle, which can guide the hot air so that the hot air can be blown out from different air guide ports 70 to the middle to achieve uniform diversion.

[0026] For further information, see Figure 6 As shown, a partition plate 72 is also included. The partition plate 72 is arranged at the middle part of the inner side of the air duct 7, which can evenly divide the air guide port 70 in the same air duct 7 into two ventilation passages, which is conducive to the uniform transportation of hot air.

[0027] For further information, see Figure 4 and Figure 5 As shown, a guide sleeve 11 is also included. The guide sleeve 11 is arranged on the left front side of the bellows 6, and the left side of the rack 10 is slidably connected to the guide sleeve 11. The guide sleeve 11 can play a role in smoothly guiding the horizontally reciprocating rack 10.

[0029] When in use, the printed materials are placed on the trays 5 respectively, the sealing door 2 is closed, the sealing cover 41 is removed, and the fan 4 and the heating tube 40 are started to work. The air heated by the heating tube 40 can be blown to the printed materials under the blowing action of the fan 4, so that the printed materials can be dried. The telescopic rod on the cylinder 9 is extended and shortened by controlling the cylinder 9, and the guide plate 8 can be driven to swing back and forth through the transmission action of the rack 10 and the gear 12, so that the hot air can be blown downward toward the middle of the drying box 1 through the guiding action of the guide plate 8, and the hot air can be guided to the air guide tubes 7 on the left and right sides respectively, and then through the diverter plate 71 and the diverter plate 72, the hot air can be blown to the middle of the drying box 1 through the diverter plate 8. The partition 72 has a guiding and evacuating effect on the hot air, so that the hot air can be blown toward the printed matter from the air guide ports 70 on the left and right sides respectively. In this way, the hot air can be evenly diverted to the printed matter by the hot air flowing from top to bottom and the hot air flowing from the left and right sides to the middle respectively, so that the hot air can be evenly diverted to the printed matter, so that the printed matter can be heated evenly, which is beneficial to improving the quality of drying the printed matter, thereby effectively avoiding uneven heating of the printed matter during the drying process. When not in use, the above-mentioned fan 4, heating tube 40 and cylinder 9 can be closed, and then the sealing cover 41 can be reset, which can play a dust-proof role for the fan 4 and the heating tube 40 and avoid dust accumulation.
