[0002] Laminated paper needs to be humidified during the production process. Currently, there are two ways to humidify it: artificial humidification and automatic humidification. Artificial humidification uses a moistened rag to rub the laminated paper, which not only increases labor costs but also reduces the efficiency of humidification. Automatic humidification uses a spray head to directly humidify the laminated paper, which results in uneven humidification. Utility Model Content

After the internal fans are started, the mounting seat is driven to rotate by wind force.

[0005] Furthermore, the auxiliary conveying mechanism comprises an arc-shaped mounting plate of a grid structure, and a plurality of auxiliary conveying rollers are arranged in the mounting plate.

[0006] Furthermore, the inner fan is symmetrically arranged with respect to the mounting seat, and the inner spray head is also symmetrically arranged with respect to the mounting seat.

[0007] After adopting the above structure, the utility model has the following beneficial effects:

[0008] The utility model can form water vapor circulation in the humidifying cylinder and humidify the upper surface of the coated paper by arranging an external fan and an external spray head; by arranging an internal fan and an internal spray head, after the internal fan is started, the mounting seat is driven to rotate by wind force, that is, the internal spray head is driven to rotate, and the inner surface of the coated paper is humidified while rotating; the internal and external humidification are combined to improve the humidification efficiency and humidification quality.

After the internal fans 13 are started, the mounting seat 12 is driven to rotate by wind force. Specifically, the coated paper enters from the inlet and outlet 3, passes through the feed roller 4, the guide roller 6, and the auxiliary conveying mechanism 9 in turn, and then is discharged from the discharge roller 5. At the same time, the external fan 7 and the external spray head 8, the internal fan 13 and the internal spray head 14 are turned on. The water vapor sprayed by the external spray head 8 circulates around the inner wall of the humidification cylinder 2 after the wind force of the external fan 7, and is evenly sprayed on the upper surface of the coated paper to humidify the upper surface of the coated paper; after the internal fan 13 is started, it drives the internal spray head 14 to rotate while evenly diffusing the sprayed water vapor to evenly humidify the inner surface of the coated paper; the internal and external humidification are combined to improve the humidification efficiency and humidification quality; the auxiliary conveying mechanism 9 guides and supports the conveying of the coated paper, which is beneficial to the transmission of the coated paper.

[0015] In this embodiment, the auxiliary conveying mechanism 9 includes an arc-shaped mounting plate 91 of a grid structure, and a plurality of auxiliary conveying rollers 92 are arranged in the mounting plate 91. The auxiliary conveying rollers 92 are used to convey the coated paper, and the mounting plate 91 of the grid structure avoids adverse effects on the diffusion of water vapor as much as possible, so that the water vapor can contact the inner surface of the coated paper.

[0016] In this embodiment, the inner fan 13 is symmetrically arranged about the mounting seat 12, and the inner spray head 14 is also symmetrically arranged about the mounting seat 12. The symmetrically arranged inner fans 13 have opposite wind directions, and the wind force generated is conducive to the rotation of the mounting seat 12 and the diffusion of the inner spray head 14.
