The corrugated paper boards continuously pass through the space between the upper drying mechanism and the lower drying mechanism, so that the corrugated paper boards can be continuously dried.

In the drying process, the corrugated board is easily warped and deformed due to the heating of the water vapor and the upper and lower drying mechanisms on the corrugated board, and the yield of the corrugated board is influenced. In addition, the moisture in the corrugated board is not easy to be emitted out of the corrugated board after being heated by the upper and lower drying mechanisms, so that the corrugated board is prevented from getting damp after being cooled.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a corrugated container board's drying device can effectually prevent that the corrugated container board after drying from cooling and getting damp to and prevent corrugated container board warpage in the stoving in-process.

In order to achieve the above purpose, the technical scheme of the utility model is that:

a drying device for corrugated boards comprises an upper drying mechanism, a lower drying mechanism and a dehumidifying mechanism which are oppositely arranged; the upper drying mechanism comprises an upper heat transfer plate and an upper heat transfer pipe, and the upper heat transfer pipe is arranged on the upper surface of the upper heat transfer plate; the upper heat transfer plate is fixedly connected with a lifting unit for driving the upper heat transfer plate to move up and down; the lower drying mechanism comprises a lower heat transfer plate and a lower heat transfer pipe, the upper part of the lower heat transfer plate is longitudinally provided with a conveying mechanism, and the lower heat transfer pipe is arranged on the lower surface of the lower heat transfer plate; the air outlet of the dehumidification mechanism is arranged between the upper heat transfer plate and the lower heat transfer plate and is used for blowing dry air into the corrugated board between the upper heat transfer plate and the lower heat transfer plate.

Furthermore, a plurality of pressurizing nozzles are arranged at the front end of the air outlet.

Further, the pressurized sprayer head is a duckbill nozzle.

Has the advantages that: through above-mentioned structure, when drying corrugated container board, because go up the stoving mechanism, lower stoving mechanism produces a compressing tightly effect to corrugated container board, thereby make corrugated container board can not take place the warpage because of high temperature and steam effect, simultaneously at corrugated container board stoving in-process, set up a dehumidification mechanism that can blow in dry air in to its clearance from its side, make the moisture of remaining difficult scattering and disappearing in the corrugated container board clearance can be taken out by the abundant of dry air, and then reduced the probability of getting damp of corrugated container board after the dry cooling.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 4, the drying device for corrugated cardboard includes an upper drying mechanism 1, a lower drying mechanism 2 and a dehumidifying mechanism 3 disposed between the two mechanisms.

The detailed structure of the upper drying mechanism comprises an upper heat transfer plate 11 which is a rectangular mechanism, and an upper heat transfer pipe 12 which is fixedly connected with the upper surface of the upper heat transfer plate. In a specific embodiment, in order to improve the uniformity of heat transfer, the upper heat transfer pipe has a serpentine structure. And a lifting unit 13 capable of driving the upper heat transfer plate 11 to move up and down is fixedly connected to the upper heat transfer plate.

Specifically, the lifting unit includes a connecting frame 131 fixedly connected to the upper heat transfer plate 11, a hydraulic cylinder 132 fixedly connected to the end of a telescopic rod and the connecting frame, and a supporting frame 133 fixedly connected to the end of the hydraulic cylinder, wherein the supporting frame is an L-shaped structure, and one end of the supporting frame is fixedly connected to the supporting surface.
