[0025] Working principle:

[0026] The deceleration motor 104 drives the connected belt roller 102 to rotate. Through another belt roller 102, the conveyor belt 103 rotates, so as to convey the printed matter. The light-shielding cover 201 is used for light shielding to reduce the influence of external light on the detection of the printed matter. The visual camera 202 is used to detect the printed matter. The servo motor 303 is driven to make the shaft roller 302 drive the storage component 304 to rotate, so that one of the storage components 304 is aligned with the conveying mechanism 1.

Then, the servo motor 303 is driven to operate, so that the shaft roller 302 drives the storage box 3041 to continue to rotate, so that the storage box 3041 containing the printed matter is aligned with another conveying mechanism 1. When the storage box 3041 containing the printed matter gradually approaches another conveying mechanism 1, the printed matter in the storage box 3041 is turned over. At the same time, the first magnet 3045 and the second magnet 3046 gradually approach, so that the repulsive force between the first magnet 3045 and the second magnet 3046 increases, so that the push plate 3043 moves outward against the elastic force of the spring 3044, so as to push out the printed matter, so that another conveying mechanism 1 conveys away the printed matter, and the detection of the other side of the printed matter is completed. The operation is very simple.
