After the paper is flattened, it is stacked, which can improve the flatness and stability of the paper stack. Moreover, the paper pressing belt 4 moves synchronously with the paper in the same direction, which can avoid the friction between the paper pressing belt 4 and the paper and affect the quality of the paper.

[0045] Furthermore, if Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, it also includes a first transmission shaft 5 and a second transmission shaft 6.

The number of the paper pressing belts 4 is at least two, and all the paper pressing belts 4 are arranged along the length direction of the first transmission shaft 5 and the second transmission shaft 6, and there is a gap between adjacent paper pressing belts 4. The conveyor belt 2 is located at the right end of the frame 1 to convey the paper to the left, the second transmission shaft 6 is located at the left end of the frame 1, the first transmission shaft 5 is located on the right side of the second transmission shaft 6, and the axes of the first transmission shaft 5 and the second transmission shaft 6 are both arranged along the front-back direction. One of the first transmission shaft 5 and the second transmission shaft 6 is connected to the rotation drive mechanism, and the rotation drive mechanism drives the paper pressing belt 4 to move through the first transmission shaft 5 and the second transmission shaft 6.

All the paper pressing belts 4 are arranged in the front-to-back direction, and there is a gap between adjacent paper pressing belts 4. In this way, the contact area between the paper pressing belt 4 and the paper can be reduced as much as possible while ensuring the flattening effect, so as to better ensure the quality of the paper.

The lifting mechanism is connected between the support frame 15 and the frame 1, and the lifting mechanism is used to drive the support frame 15 to move upward or downward, and the support frame 15 drives the tray 3 to move upward or downward synchronously. During the movement of the support frame 15, the longitudinal slider 16 slides along the longitudinal slide rail 17, which can play a guiding and limiting role for the support frame 15, and the stability is better. At least two longitudinal slide rails 17 are set on both the front and rear sides of the frame 1, and all the longitudinal slide rails 17 on the same side of the frame 1 are arranged in the left and right directions. The longitudinal sliders 16 and the longitudinal slide rails 17 are set one by one. Multiple longitudinal sliders 16 and the longitudinal slide rails 17 jointly carry the support frame 15, which can prevent the tray 3 and the support frame 15 from being bent due to heavy pressure.

[0051] Furthermore, if Figure 1 and Figure 3 As shown, the third transmission shaft 18 and the stacking belt 19 are also included. The third transmission shaft 18 is arranged at both ends of the support frame 15.

The upper end surface of the tray 3 is flush with the highest point of the third transmission shaft 18. The stacking belt 19 is located between the left and right third transmission shafts 18. When the paper stack on the tray 3 reaches the set height, the third transmission shaft 18 is driven to rotate by the rotary drive mechanism, thereby driving the stacking belt 19 to move, and the paper stack on the tray 3 can be transported to the next station, eliminating the process of manual handling, saving time and effort.

[0052] Furthermore, if Figure 1 and Figure 3 As shown, there are at least two stacking belts 19, all of which are arranged along the length direction of the third transmission shaft 18, and there are gaps between adjacent stacking belts 19.
