Edge suction device with variable material suction position

The utility model relates to an edge suction device with a variable material suction position. The edge suction device comprises a material suction piece, a connecting hose, a fan and a fixing frame, the material suction part comprises a material suction air pipe and a material suction head; an inclined plate is arranged in the material suction opening; the two ends of the material suction air pipe are both communicated with the connecting hose, and the material suction air pipe is connected with the fan through the connecting hose. The waste edge collecting device has the advantages that the horizontal position of the material suction piece is rapidly adjusted through the fixing piece so as to meet the requirement for collecting waste edges of coiled materials with different breadths, and the situation that the waste edges of the coiled materials are too far away from the material suction piece, and the edge suction efficiency is affected is avoided; the structure is simple, negative pressure is generated on
