When the paper taking device is used, one material receiving plate 92 firstly moves to the position of the lowest point of the paper taking frame 951 under the action of the lifting device 93, then paper sheets taken down from the last conveying strip 911 by the paper taking frame 951 fall on the material receiving plate 92, and along with the increase of the number of the paper sheets, the lifting device 93 drives the material receiving plate 92 to move downwards, so that the uppermost position of the paper sheets stacked on the material receiving plate 92 is located at the lowest point of the paper taking frame 951. When the stacking amount of the paper sheets on one receiving plate 92 reaches the designed height, the other receiving plate 92 moves horizontally to be inserted into the lowest point of the paper taking frame 951, the receiving plate 92 with the paper sheets is moved downwards to the position of the material conveying belt 96, the push-pull motor 971 drives the push-pull slide block 973 to move the receiving plate 92 towards the corresponding material removing plate 94, the paper sheets on the receiving plate 92 are further stopped at one side of the material removing plate 94 where the material conveying belt 96 is arranged, the paper sheets fall on the material conveying belt 96, and then the receiving plate 92 performs the next cycle.

Referring to fig. 13, a pressing plate 98 for extruding the stacked paper sheets is arranged above the material conveying belt 96, the pressing plate 98 is used for extruding gas in the stacked paper sheets, a pressing cylinder 99 is connected to the pressing plate 98, the pressing cylinder 99 is vertically arranged, the pressing cylinder 99 is fixed on the frame 10, an output end of the pressing cylinder 99 is fixed with the pressing plate 98, and the pressing plate 98 is horizontally arranged, so that the pressing plate 98 can move up and down under the action of the pressing cylinder 99.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
