[0017] like Figure 1 to Figure 2 As shown,

[0018] A carton drying device, characterized in that it includes a drying box 2 and a conveyor belt 3, wherein the drying box 2 is provided with an inlet 4 on one side and an outlet 5 on the other side, the conveyor belt 3 is located on the side of the inlet 4, a plurality of conveying rollers 6 are rotatably connected in the drying box 2, and the height of the conveying rollers 6 is the same as that of the conveyor belt 3, an upper hot air blower 7 is provided at the top of the drying box 2, and the air outlet end of the upper hot air blower 7 faces downward, a lower hot air blower 8 is provided at the bottom of the drying box 2, and the air outlet end of the lower hot air blower 8 faces upward, and door curtains 9 are provided at the inlet 4 and the outlet 5.

[0019] In this embodiment, the carton board to be dried is placed on the conveyor belt 3, and the conveyor belt 3 drives the carton board through the door curtain 9 at the entrance 4 and enters the drying box 2. After entering the drying box 2, the carton board falls on the conveying roller 6, and the conveying roller 6 drives the carton board forward. The upper hot air blower 7 and the lower hot air blower 8 blow air at the same time to dry the upper and lower surfaces of the carton. There is no need for manual turning over, and the efficiency is greatly improved. Finally, the dried carton passes through the door curtain 9 at the exit 5 and moves out of the drying box 2. Passing through the door curtain 9 does not hinder the entry and exit of the carton, and can reduce heat loss, thereby ensuring the temperature in the drying box 2 and improving the drying effect.

[0020] In this embodiment, a slide plate 10 is symmetrically provided inside the drying box 2, the door curtain 9 is fixedly connected to the lower end of the slide plate 10, and a first push rod motor 11 is provided on the drying box 2 to drive the slide plate 10 to move up and down. When the carton board enters and exits the drying box 2, the first push rod motor 11 drives the slide plate 10 to rise, so that the door curtain 9 is pulled up. After the carton board enters and exits, the first push rod motor 11 drives the slide plate 10 to descend, so that the door curtain 9 is pulled down to reduce heat loss. The door curtain 9 automatically rises and falls to prevent the door curtain 9 from affecting the carton board entering and exiting the drying box 2.

[0021] In this embodiment, the conveying roller 6 is a metal mesh roller. The hot air sprayed by the lower hot air blower 8 can pass through the metal mesh roller and be sent to the bottom of the carton board, thereby increasing the contact area between the hot air and the carton board.
