The utility model discloses a device for reducing paper feeding friction force of a paper receiving unit of a gravure press. The device comprises a paper feeding hole, wherein both sides of a lathe bed on the paper feeding hole are provided with arc-shaped air pipes; compressed air is introduced into the arc-shaped air pipes; the arc-shaped air pipes are positioned between unreeled paper and spare paper; and the air nozzle ends of the two arc-shaped air pipes are obliquely opposite to each other. After the device is adopted, compressed air is jetted from air nozzles of the arc-shaped air pipes, and compressed air current flows between the unreeled paper and the spare paper for isolating the unreeled paper from the spare paper and preventing the unreeled paper from being contacted with the spare paper in the moving process, so that friction force is not generated between the unreeled paper and the spare paper, and the unreeled paper moves stably. The device has the advantages of simple structure, good friction force reducing effect and stable and reliable work.
