[0009] As a further solution of the utility model, support legs are provided at the four corners of the conveyor belt conveyor 1 and the conveyor belt conveyor 2, and the height of the conveyor belt conveyor 1 is higher than the height of the conveyor belt conveyor 2.

[0010] As a further solution of the utility model, the steering direction of the guide roller is opposite to a direction of the conveyor belt conveyor.

[0011] The advantage of the utility model over the prior art is that a motor is provided to drive the gear to rotate, and the gear drives the gear racks on both sides to move closer to or away from each other, so that the distance between the limit plates can be adjusted according to the size of the paper, thereby avoiding the problem that the paper cannot be folded to a suitable position due to deviation when the paper is loaded.
