[0002] Environmentally friendly cardboard is an environmentally friendly packaging material produced from recycled waste paper. It is mainly divided into three types: single gray, double gray and full gray. It has physical properties such as quantity, thickness, longitudinal and transverse directions and air permeability. It is widely used in packaging boxes, liners and partitions. The screening process is a key step to ensure that waste materials can be effectively recycled and reused. During the screening process, the waste materials are output to the screening equipment through the die-cutting equipment. Usually, the cardboard is transported by a belt drive structure with an array of equidistant arrangements. The die-cut waste boards fall through the gaps reserved between the belts to the conveyor belt below, thereby separating the finished products from the fertilizer.

[0024] According to the above structure, the middle partition 111 is rotatably connected to the rotating rod 102, and the position of the middle partition 111 remains fixed. The rotating rod 102 is rotated by the handle 104. Since the screw 117 is screwed to the threaded groove 116, and the screw 117 is connected to the side plate 110 through the connecting rod 118, and the side plate 110 is restricted by the limiting rod 103 and will not rotate, when the rotating rod 102 rotates, the screw 117 will move from the storage groove 115 along the rotating rod 102 to the outside of the middle partition 111, and the two threaded grooves 116 are opened as mirror images of each other, which determines that the movement paths of the two screws 117 are linearly opposite directions, thereby driving the two side plates 110 away from each other and moving toward the outside of the middle partition 111, so that the size of the gap between the two middle partitions 111 can be adjusted.
