Place the corrugated cardboard on the conveyor belt (408), start the motor 1 (401) to drive the rotating shaft 1 (403) to rotate, the rotating shaft 1 (403) drives the driving wheel (404) to rotate, the driving wheel (404) drives the driven wheel (406) to rotate through the transmission belt (405), and when the transmission belt (405) rotates, it drives the extrusion plate (413) to move; S2, when the extrusion plate (413) moves to the trapezoidal block (410), it will be pressed down by the trapezoidal block (410), at this time, the spring (412) and the telescopic tube (411) are stretched, and at the same time, the plug block (414) is inserted into the socket and moves with the conveyor belt (408), when the extrusion plate (413) moves to the other side of the trapezoidal block (410), the plug block (414) is separated from the socket, so that the conveyor belt (408) stops moving; S3, the motor 2 (501) is started to drive the rotating shaft 2 (502) to rotate, the rotating shaft 2 (502) drives the circular gear 1 (503) to rotate, the circular gear 1 (503) drives the fan gear 1 (504) to rotate, the fan gear 1 (504) drives the circular gear 2 (505) to rotate, the circular gear 2 (505) drives the fan gear 2 (506) to rotate, the fan gear 1 (504) and the fan gear 2 (506) drive the sliding plate (508) to move back and forth in the installation box (511), and the sliding plate (508) drives the storage box (509) to move back and forth, so that the adhesive can be sprayed on the surface of the corrugated cardboard; S4. During the movement of the sliding plate (508) and the sliding bar (510), the sliding bar (510) drives the push plate (513) to move. When the push plate (513) moves, it squeezes the air bag (514), thereby continuously generating airflow. The airflow is blown out through the blowing pipe (515) to clean the smaller dust on the surface of the corrugated cardboard.
