In the description of the present invention, the term "downstream" refers to the conveying direction of the printed matter. For example, the pre-accelerated suction belt 2 is located downstream of the hairpin sleeve 1, which means that the printed matter can be transported from the hairpin sleeve 1 to the pre-accelerated suction. On the belt 2.
[0029] The upper suction belt 3 is located above the pre-acceleration suction belt 2 and downstream of the pre-acceleration suction belt 2.

When the printed matter is transported to the upper suction belt 3, the printed matter is smoothly transferred to the upper suction belt 3 through the second suction assembly 31, and the lower detection component 6 performs the inspection on the reverse side of the printed matter. Detection. When the printed matter is transported to the lower suction belt 4, the printed matter is transferred to the lower suction belt 4 through the third suction assembly 41, and the upper detection component 5 detects the front side of the printed matter, thereby realizing double-sided detection of the printed matter . Among them, the upper detection component 5 and the lower detection component 6 can be connected to the control unit, and the detection information is fed back to the control unit.
