The invention discloses a remanufacturing treatment device for door seal rubber sleeve or soft magnetic stripe waste. The remanufacturing treatment device is characterized in that the remanufacturing treatment device comprises a forced feeding structure and a broken material conveying structure; the forced feeding structure comprises feeding driven gears, a feeding shaft and a feeding machine shell; the feeding driven gears are mounted at the two ends of the feeding shaft; the broken material conveying structure comprises a material breaking threaded rod, a power threaded rod, a conveying shell and a closed shell; the material breaking threaded rod is connected with the power threaded rod and stretches into the conveying shell, driving gears are arranged on the power threaded rod which is externally connected with a power gear box, and the feeding driven gears are engaged with the driving gears on the power threaded rod; the door seal rubber sleeve and soft magnetic stripe waste is sent into the broken material conveying structure through the forced feeding structure, and the power threaded rod in the broken material conveying structure drives the material breaking threaded rod to break materials; and the broken materials are extruded out of the conveying shell while the material breaking threaded rod breaks the materials. According to the remanufacturing treatment device for the door seal rubber sleeve or soft magnetic stripe waste, the treatment procedure of the door seal rubber sleeve and the soft magnetic stripe is simplified, the recycling cost is reduced, and the device is suitable for remanufacturing treatment of the door seal rubber sleeve and soft magnetic stripe waste.
