Single-paper code spraying, paper collecting and air blowing device

The utility model relates to the technical field of blowing devices, and discloses a single-paper code spraying, paper collecting and blowing device which comprises a main body, a transmission mechanism arranged in the main body and a correction mechanism arranged at the bottom end of the main body, the correction mechanism comprises a fixing frame, and a fixing box is fixedly installed at the top end of the fixing frame. A friction strip drives paper to move, in the moving process, a second driving motor drives a gear to rotate, the gear drives a first rack and a second rack to move relatively, in the moving process of the first rack and the second rack, a fixing plate is driven to move relatively, and then the fixing plate drives a correcting plate to move relatively. And then the surfaces of the two correcting plates make contact with the two ends of the paper at the same time, in the contact process, the angle of the paper can be adjusted, the front end of the paper is right opposite to the surface of the
