Aiming at the defects of the prior art, the technical problems to be solved by the invention are as follows: how to provide a paper buttress neatly uses transport vechicle that structural design is reasonable, operation convenient to use is favorable to reducing workman intensity of labour, improves running efficiency and product quality.

In order to solve the technical problems, the invention adopts the following technical scheme:

a transport vehicle for neatening paper stacks is characterized by comprising a bottom plate, a back plate and two side plates, wherein the back plate is vertically arranged on the bottom plate along the side edge of the bottom plate, the two side plates are vertically arranged on the back plate and the bottom plate, and the distance between the two side plates is consistent with the length or width of the paper stacks to be stacked; universal wheels are uniformly distributed at the bottom of the bottom plate; the paper pile neatening device is mounted on one side, facing the other side plate, of at least one side plate and comprises a neatening plate arranged in parallel with the side plates, a plurality of guide columns facing the side plates are uniformly distributed on the edge of the neatening plate, guide holes corresponding to the guide columns are formed in the side plates, the guide columns penetrate through the guide holes, stop blocks are arranged at the end portions of the guide columns, and compression springs are sleeved on the guide columns between the stop blocks and the side plates; the paper pile neatening device further comprises a pushing mechanism arranged between the neatening plate and the side plate, the pushing mechanism comprises inclined wedge blocks which are arranged on the side plate and the neatening plate in a matched manner in pairs, and inclined wedge surfaces of the inclined wedge blocks which are arranged in a matched manner in pairs are arranged oppositely; the inclined wedge blocks on the side plates or the leveling plates are arranged on the moving ends of linear pushing mechanisms which are arranged in parallel with the side plates, and the linear pushing mechanisms are arranged on the side plates or the leveling plates.

By adopting the structure, when the cut printed matter is placed on the paper stack, the moving end of the linear pushing mechanism can be utilized to drive the inclined wedge blocks to move linearly, the linear motion of the linear pushing mechanism is converted into the horizontal movement of the alignment plate by utilizing the cooperation between the two inclined wedge blocks, and the edges of the stacked paper stack are pushed and arranged, so that the stacked paper stack can be kept aligned at each time. The linear pushing mechanism and the side plate are arranged in parallel, so that the longitudinal size between the side plate and the trimming plate can be reduced.

Further, the linear pushing mechanism comprises a pushing screw rod vertically arranged, and one end of the pushing screw rod is coaxially connected with a pushing motor; and two ends of the pushing screw rod are rotatably arranged on the side plates or the aligning plates through bearing seats.

Furthermore, a supporting plate is also arranged on the bottom plate, and two ends of the supporting plate extend out of the bottom plate along the width direction of the back plate and form a protruding part for lifting; the side plates and the aligning plate are provided with a plurality of first abdicating holes which are uniformly distributed along the direction vertical to the back plate, the first abdicating holes vertically extend into a strip shape, and a side plate strip is formed between every two adjacent first abdicating holes; the supporting plate is provided with a plurality of second yielding holes correspondingly arranged with the side plate strips, and the side plate strips correspondingly penetrate through the second yielding holes in the supporting plate.

Therefore, the supporting plate can be integrally lifted by the protruding parts of the supporting plate when in use, the stacking position is guaranteed to be higher at each time, frequent bending of workers is avoided, the supporting plate is gradually lowered along with the increase of the height of the stacked paper stacks, and the labor intensity of the workers is reduced. In addition, first hole of stepping down is the strip along vertical extension, and the curb plate strip passes the second hole of stepping down on the layer board correspondingly, can guarantee the corrective action of curb plate strip to the paper pile side promptly, can not hinder the lift of layer board again.
