The invention discloses a paper receiving device for a corrugated paper board production line. The paper receiving device comprises a fixing plate; sliding grooves are formed in the upper end and thelower end of the fixing plate; inserting blocks are arranged in the two sliding grooves; limiting cavities are formed in the inner walls of the two sliding grooves; guide rods are arranged in the limiting cavities and are fixedly connected onto the inner walls of the limiting cavities through first elastic devices; one end, far away from the corresponding first elastic device, of each guide rod isfixedly connected onto the side wall of the corresponding inserting block; pulling rods are arranged on the side walls of the guide rods, penetrate through the inner walls of the sliding grooves andare movably connected with the fixing plate; a handle is arranged at one end, far away from the corresponding guide rod, of each pulling rod; inserting rods penetrate through the side wall of the fixing plate and are movably connected with the fixing plate; and inserting grooves corresponding to the inserting rods in position are formed in the side walls of the inserting blocks. The paper receiving device is reasonable in structural design, easy to operate, quick, reliable and not prone to slipping, the paper feeding efficiency for corrugated paper boards is greatly improved, and meanwhile, adisc head extrudes by the aid of a buffering mechanism and does not press the corrugated paper boards easily.
