[0030] Working principle:

[0031] In the working process of the dehumidification device for corrugated paper production, first, in the initial state, the first motor 73 is started to drive the screw rod 72 to rotate, and then drive the sliding block 74 and the placing rack 5 to rise to the appropriate height, so that the bottom layer of the placing layer 6 of the placing rack 5 is flush with the conveying belt 1 inputting the corrugated paper, at this time, the corrugated paper is input into the bottom layer of the placing layer 6 in the placing rack 5 through the conveying belt 1, and the first rotating rod 62 and the second rotating rod 84 of the driven rotating block 81 on the surface side of the bottom layer of the placing layer 6 are on the same center line; then, the second motor 88 is started to drive the first rotating rod 62 and the rotating stick 63 fixedly connected on the surface of the first rotating rod 62 to rotate through the coordinated action of the worm 86, the turbine 85, the rotating plate 82 and the driven rotating block 81, so that the corrugated paper moves horizontally on the placing layer 6 to adjust the position of the corrugated paper, when the corrugated paper completely enters the bottom layer of the placing layer 6, the first motor 73 is started again to drive the screw rod 72 to rotate to make the placing rack 5 descend, due to the influence of the weight and the gravity distribution relationship, the side of the first rotating rod 62 fixedly connected with the driven rotating block 81 is relatively heavy during the descending process of the placing rack 5, according to the characteristics that the gravity center of the object tends to be stable, it will naturally be in the lower position, the driven rotating block 81 on the placing rack 5 will always be between the two rotating plates 82, and will not hinder the descending process of the placing rack 5; when the second-to-last layer of the placing layer 6 is flush with the conveying belt 1 inputting the corrugated paper, the second motor 88 is started again to repeat the above steps to make the corrugated paper move horizontally on the placing layer 6 and adjust the position, and the cycle is repeated until the corrugated paper is placed in each layer of the placing layer 6; at this time, the protective plate 51 at the top end of the placing rack 5 is flush with the top end of the lower cavity 4, which helps to reduce the heat loss, improve the energy utilization efficiency, and make the hot air generated by the heating pipe 11 and the air inlet fan 10 better concentrated in the inside of the placing rack 5 and the lower cavity 4.

[0032] Subsequently, the air inlet fan 10 and the heating pipe 11 are started to send the heated air into the lower cavity 4, at the same time, the third motor 121 drives the guide plate 125 to adjust the wind direction, so that the hot air uniformly blows to the corrugated paper on the placing rack 5, and the air outlet fan 9 exhausts the humid air to realize the dehumidification of the corrugated paper.

[0033] When the dehumidification is completed, the first motor 73 is started again to drive the screw rod 72 to rotate to drive the sliding block 74 and the placing rack 5 to rise, so that the first layer of the placing layer 6 is flush with the conveying belt 1 outputting the corrugated paper, then the second motor 88 is started to make the corrugated paper conveyed from the placing layer 6 to the conveying belt 1 outputting the corrugated paper for the next work; when the corrugated paper completely leaves the first layer of the placing layer 6, the first motor 73 is started to drive the screw rod 72 to rotate to drive the sliding block 74 and the placing rack 5 to continue to rise, so that the second layer of the placing layer 6 is flush with the conveying belt 1 outputting the corrugated paper, the second motor 88 is started again to make the corrugated paper completely leave the second layer of the placing layer 6, and the cycle is repeated until the corrugated paper in each layer of the placing layer 6 enters the conveying belt 1 outputting the corrugated paper and is conveyed to other processes.
