The invention discloses a corrugated paper code spraying device and relates to the technical field of corrugated paper. A conveying frame is included; the two sides of the lower end of a fixed frame are each fixedly connected with a movable supporting block; a movable sliding groove is formed in each movable supporting block; a limiting sliding rod is connected to each movable sliding groove in asliding manner; the bottom end of a pushing rod in a sliding connection with the interior of each limiting sliding rod through a limiting block; the top end of an upper pressing plate is fixedly connected with a buffering device; the surface, located below a lower pressing plate, of the portion a pressure stabilizing rod is sleeved with a pressure stabilizing spring; the bottom end of the pressurestabilizing rod is fixedly connected with a pressure stabilizing block; a code spraying block is fixedly connected with the middle position of the bottom end of the low pressing plate; and the middleposition of the top end of the conveying frame is fixedly connected with a corrugated paper clamping device. The corrugated paper code spraying device achieves the purposes that during code spraying,the periphery of corrugated paper for code spraying is fixed, it is guaranteed that code spraying is free of deflection, and code spraying is clear, and the buffering effect during downward pressingof code spraying is guaranteed; and it is prevented that because pressure is too large, the corrugated paper is damaged.
