[0020] The circumference of the flap conveyor belt 2 has multiple vertical bodies arranged at equal intervals. Specifically, the number of the flap conveyor belts 2 is four, and the four or more flap conveyor belts 2 are arranged at equal intervals. The flap conveyor belt 2 includes multiple sprockets 21 and chains 22. The chains 22 are arranged around the circumference of the multiple sprockets 21, and the vertical bodies include vertical rods 23. Multiple vertical rods 23 are detachably connected to the chains 22. A connecting plate is formed at the lower end of the vertical rod 23. The two sides of the connecting plate are connected to the chains 22 by screws. The distance between adjacent vertical rods 23 on the same flap conveyor belt 2 is the thickness of two to four plate bodies. 1-2 cardboards can be placed between adjacent vertical rods 23. The height of the vertical rod 23 is equal to two-thirds to one-half of the height of the cardboard. In this scheme, the height of the vertical rod 23 is one-half of the height of the cardboard, so the cardboard will not fall out from between the vertical rods 23.
