The invention discloses an anti-breakage buffering device for tobacco block encasement. The anti-breakage buffering device comprises a machine frame and a receiving device. The machine frame comprises a top plate, guide rods and a first air cylinder, wherein the guide rods are fixed to the bottom of the top plate and are vertically arranged, the first air cylinder is fixed to the top of the top plate, a piston rod of the first air cylinder penetrates through the top plate and is telescoped downwards, and the free end of the piston rod of the first air cylinder is fixedly connected with the receiving device. Guide rod sleeves are arranged in the receiving device, and the guide rods are located in the guide rod sleeves in a sliding connection mode. Before being fed into a conveying box by a feeding device, material is thrown into the receiving device of the anti-breakage buffering device close to the feeding device, then buffering doors of the receiving device are opened for placing the material into the conveying box stably, and therefore the problems that when the material is directly thrown into the conveying box in a free falling mode, serious raise dust, high noise and material breakage are caused can be solved.
