The invention relates to a medical gauze processing device. The device is characterized in that a cutting device comprises a cutting support frame, wherein the cutting support frame is installed on abottom plate; and a cutting limiting frame is arranged on the rear side of the upper end of the cutting support frame, cutting limiting grooves are formed in the cutting limiting frame at equal intervals from left to right, a cutting rack is arranged on the front side of the upper end of the cutting support frame, and cutting adjusting mechanisms are connected to the cutting rack at equal intervals from front to back. According to the medical gauze processing device, the problems that in the production and processing process of an existing medical gauze, the gauze needs to be cut by controlling a machine manually, the cut gauze needs to be wound by means of an existing device, the cutting accuracy is difficult to guarantee when the gauze is cut by manually controlling the machine, the gauze can not be accurately cut according to regulations, resource waste is easily caused, and after the gauze is wound, instruments wound with the gauze need to be disassembled manually by means of the existing device, the operation is complex, the stability is poor, the labor intensity is large, and the working efficiency is low can be solved.
