[0001] The utility model relates to the field of carton production, in particular to a drying device used for folding carton production. Background Art

[0002] Cartons are made of glued paperboards. The manufacturing of paperboards needs to go through the main and back exposure, plate washing, drying and debonding processes before printing. A Chinese utility model patent with the announcement number CN213747730U discloses a dewaxing and drying device for carton production, which mainly includes a dryer, a conveyor belt and a support frame. When the cardboards are piled on the rollers, the dewaxing and drying device for carton production puts down the cardboards one by one, which is conducive to drying the cardboards more thoroughly. At the same time, it is conducive to adjusting the distance between the rollers by adjusting the distance between the side plates, so as to match cardboards of different sizes.

When the supporting sleeve 1 52 and the supporting sleeve 2 62 are in contact with the surface of the cardboard, as the cardboard moves to the left, the contact positions of the lower surface of the cardboard and the supporting sleeve 1 52 and the supporting sleeve 2 62 will be staggered, so that the suspension time at the same position is increased, so that it can be dried more fully and more evenly.

[0031] The conveying roller 1 51 and the conveying roller 2 61 are both a transmission shaft, and the rear ends of the two pass through the rear frame 1 and are placed behind the frame 1. The rear ends of the plurality of conveying rollers 1 51 and the conveying roller 2 61 are connected and driven by sprockets and chains.

[0032] The front end of the rightmost conveying roller 1 51 passes through the front frame 1, and is connected to the output shaft of the motor through a sprocket and a chain, so as to facilitate the movement of the conveying member 1 5 and the conveying member 2 6, and enable the cardboard placed above them to move from right to left.

[0033] The front sides of multiple air outlet pipes 1 21 are connected to the lower air pipe 2, and the front sides of multiple air outlet pipes 2 31 are connected to the upper air pipe 3, and the lower air pipe 2 and the upper air pipe 3 are connected to an external hot air blower through a main pipe.
