A second rack 17 is arranged on the moving frame 7, the second rack 17 is meshed with a driving gear 18, a slide is arranged on the moving frame 7, and a slide rail matching the slide is arranged on the first lifting seat 6. By controlling the rotation of the driving gear 18, the moving frame 7 can be driven to move along the second rack 17. A paper supporting belt 14 is wound around the movable frame 7, a connecting piece 21 is fixedly provided on the first lifting seat 6, the paper supporting belt 14 is fixedly connected to the connecting piece 21, the second lifting seat 8 is arranged on the first lifting seat 6, a second motor is arranged on the second lifting seat 8, the second motor is transmission-connected to the first rotating shaft, a first gear is connected to the first rotating shaft, the first lifting seat 6 is connected to the connecting seat 23 through a connecting column 22, a first rack 20 meshing with the first gear is arranged on the connecting seat 23, a first guide wheel is arranged on the second lifting seat 8, the first guide wheel is movably arranged in the first guide groove 9 of the connecting seat 23 on the first lifting seat 6, and the second lifting seat 8 can be driven to rise and fall under the guidance of the first rack 20 and the first guide groove 9 by controlling the rotation of the gear. A first moving seat 10 is also provided on the second lifting seat 8, a paper support board 12 is provided on the first moving seat 10, a second cylinder 11 is provided on the second lifting seat 8, the piston rod of the second cylinder 11 is connected to the first moving seat 10, and the first moving seat 10 can be driven to move by controlling the action of the second cylinder 11. A lower paper baffle board 3 is provided at the discharge end of the paper feeding assembly 15, a second moving seat 4 is provided on the first lifting seat 6, a first cylinder 13 is provided on the connecting member 21, the piston rod of the first cylinder 13 is connected to the second moving seat 4, and the second moving seat 4 can be driven to move by controlling the first cylinder 13.

Furthermore, the paper lift board 5 and the lower paper baffle board 3 are staggered to ensure that papers of different specifications and positions are blocked.

[0022] The working principle of the utility model is as follows: the paper is delivered by the paper feeding assembly 15 and stacked on the paper receiving tray on the lifting frame 1. After the paper on the lifting frame 1 is collected to the required amount, the lifting frame 1 descends to the bottom so as to take away the paper receiving tray with the paper stacked thereon and replace it with a new paper receiving tray. During the descending process of the lifting frame 1, the first lifting seat 6 is first controlled to drive the paper supporting belt 14 and the lifting paper board 5 to rise to a suitable height, and then the first moving seat 10 is controlled to drive the supporting paper board 12 to move, and then the second lifting seat 8 is controlled to drive the supporting paper board 12 to rise, so that the supporting paper board 12 can hold the paper newly delivered by the paper feeding assembly 15. As the paper is stacked, the second lifting seat 8 is controlled to drive the supporting paper board 12 to descend. When the supporting paper board 12 descends to the lifting paper board 5, the second moving seat 4 is controlled to drive the lifting paper board 5 to extend, so that one side of the paper is stacked on the lifting paper board 5, and the supporting paper board 12 continues to descend. The paper is then separated from the paper by the paper lifting belt 14, and then the movable frame 7 is controlled to move, driving the paper supporting belt 14 to move to the top of the lifting frame 1. At this time, part of the paper is stacked on the paper supporting belt 14, and as the paper is continuously stacked, the first lifting seat 6 is controlled to drive the lifting paper board 5 and the paper supporting belt 14 to descend synchronously. When the lifting frame 1 is replaced with a new paper receiving tray and rises to the paper supporting belt 14, the movable frame 7 is controlled to drive the paper supporting belt 14 to retract inwardly, so that the paper on the paper supporting belt 14 can fall onto the paper receiving tray, and because the paper supporting belt 14 is connected to the connecting piece 21, during the movement of the movable frame 7, the paper supporting belt 14 will perform a reverse action to reduce the friction when it contacts the paper, until the paper is completely separated from the paper supporting belt 14, and then the second movable seat 4 is controlled to drive the lifting paper board 5 to retract inwardly, and the stacked paper is separated from the lifting paper board 5, so that the paper is completely transferred to the paper receiving tray, and the subsequent stacking and collection operations are continued.

[0023] The structure of the utility model, by additionally arranging a second movable seat on the first lifting seat, and arranging a lifting paper board on the second movable seat, and the lifting paper board can be synchronously lifted and lowered with the paper supporting belt, so that in the pre-paper collection process, the bottom end of the stacked paper is always placed on the lifting paper board, which reduces the contact area between the bottom paper and the paper supporting belt, reduces the paper deviation caused by friction and the like when the paper supporting belt is separated from the paper, and further improves the stability and flatness of the paper stacking and collection.
