Wherein, after the paper conveyed to the stacking bin 200 by the conveying assembly 100 is fully stacked, the paper is required to stop to enter the stacking bin 200 again, so as to take out the paper in the stacking bin 200, because the conveying assembly 100 is not stopped, the paper entering the stacking bin 200 is intercepted by the smearing prevention intercepting assembly 300, specifically, the lifting plate 310 is controlled to be at the second position, at this time, the paper is continuously conveyed to the lifting plate 310 by the intersection point of the lifting plate 310 and the conveying surface of the conveying assembly, and the friction between the paper and the conveying assembly 100 is reduced to the minimum, so as to achieve the functions of intercepting and smearing prevention, which will be explained in more detail below.

For ease of understanding, it is necessary to first explain the operation of the conveying assembly 100 to convey a plurality of sheets stacked in the conveying direction of the conveying assembly 100, that is, along the conveying direction, a previous sheet portion falls below a next sheet portion so that the plurality of sheets can be stacked on the lifting plate 310.

The conveying assembly 100 in this embodiment includes two oppositely disposed conveyor belts, the two conveyor belts are disposed in parallel, the top portions of the two conveyor belts form a conveying surface, and a gap is formed between the two conveyor belts.

The stacking compartment 200 in this embodiment is a structure for stacking and storing paper sheets, which is conceivable to those skilled in the art, and will not be illustrated or described in detail herein.

The feeding assembly is provided with a feeding end and used for sequentially feeding a plurality of paper sheets onto the conveying surface, and any two adjacent paper sheets on the conveying surface are partially overlapped.

The feeding assembly is a paper feeding mechanism (not shown), which is a structure that can be conceived by those skilled in the art to sequentially feed a plurality of sheets onto the conveying assembly 100, and will not be illustrated and described herein.

It should be noted that, in order to overlap any two adjacent paper sheets on the conveying surface, the feeding speed of the feeding assembly may be controlled by controlling the feeding speed of the feeding assembly, and the larger the feeding speed of the feeding assembly is, the larger the overlapping area of two adjacent paper sheets on the conveying surface is, the smaller the feeding speed of the feeding assembly is, and the smaller the overlapping area of two adjacent paper sheets on the conveying surface is.

To facilitate understanding, a process of how a plurality of paper sheets are conveyed to the conveying surface of the conveying assembly 100 will be described in detail, when the feeding end of the feeding assembly feeds one of the paper sheets to the conveying surface, the paper sheet is laid on the conveying surface, since the moving track of the paper sheet is constant in the process of conveying the paper sheet to the conveying surface by the feeding assembly, when the next paper sheet is conveyed, the next paper sheet is pressed against the previous paper sheet by controlling the feeding speed, so as to achieve the above process.

In a preferred embodiment, as shown in fig. 2, the lifting plate 310 includes a fixing portion 311, a bending portion 312, and an intercepting portion 313 sequentially connected along the conveying direction of the conveying assembly 100, the fixing portion 311, the bending portion 312, and the intercepting portion 313 are all disposed below the conveying surface, the fixing portion 311 is fixedly disposed relative to the conveying assembly 100, and the intercepting portion 313 can move to pass through the gap by bending of the bending portion 312.

Wherein both conveyor belts are arranged obliquely upwards along their conveying direction, facilitating the stacking of the sheets onto the lifting plate 310.

In a preferred embodiment, the intercepting part 313 is a flat plate, and the length of the flat plate is greater than that of the paper sheet, so that the paper sheet can stay on the intercepting part 313 to realize complete separation between the paper sheet and the conveyor belt. Of course, if the length of the flat plate is smaller than that of the paper, the partial separation function of the paper and the conveyor belt can still be realized, but the risk of smearing still exists, and the smearing area is greatly reduced.

In a preferred embodiment, the bending portion 312 is an elastic piece. In order to facilitate driving the intercepting part 313 to pass through the gap, in a preferred embodiment, the intercepting part 313 further comprises a driving member 320, an output end of the driving member 320 abuts against a bottom of the intercepting part 313, and the driving member 320 can push the intercepting part 313 to move and enable the intercepting part 313 to pass through the gap through bending of the elastic sheet.

In another preferred embodiment, the bending portion 312 is a hinge. In order to facilitate the driving of the intercepting part 313 through the gap, in another preferred embodiment, a driving member 320 is further included, and an output end of the driving member 320 is slidably hinged with the bottom of the intercepting part 313.

The apparatus further comprises a base 400, wherein the conveying assembly 100 and the lifting plate 310 are fixedly connected to the base 400, and the lifting plate 310 is fixedly connected to the base 400 through a supporting base 410.

It should be noted that, when the intercepting part 313 intercepts, one side of the intercepting part 313 far away from the bending part 312 should pass through the gap, and the top of the intercepting part 313 forms an angle with the conveying direction.

The working process is as follows: after the stacking bin 200 is fully stacked with paper, the driving member 320 is started to push the intercepting part 313 to rotate around the fixing part 311, the rotation is realized through the bending of the bending part 312 until the intercepting part 313 passes through the gap, at this time, the conveyor belt can continuously convey the paper to the intercepting part 313, the paper to be subsequently input to the stacking bin 200 is completely stacked on the intercepting part 313, after the paper in the stacking bin 200 is taken out, the driving member 320 is started to reset the intercepting part 313, the paper on the intercepting part 313 falls onto the conveyor belt again, and the conveyor belt continuously conveys the paper to the stacking bin 200.

Compared with the prior art: after the sheets conveyed to the stacking bin 200 by the conveying assembly 100 are fully stacked, the sheets need to stop entering the stacking bin 200 again, so that the sheets in the stacking bin 200 can be taken out, since the conveying assembly 100 is not stopped, the sheets entering the stacking bin 200 are intercepted by the smearing preventing intercepting assembly 300, specifically, the lifting plate 310 is controlled to be in the second position, the sheets are continuously conveyed onto the lifting plate 310 through the intersection point of the lifting plate 310 and the conveying surface of the conveying assembly, and the friction between the sheets and the conveying assembly 100 is minimized, so as to achieve the functions of intercepting and smearing preventing.
