The utility model provides an edging device for processing a fireproof door, which comprises a side plate, an inner roller carrier and an outer roller carrier which are respectively arranged on the inner side and the outer side of the upper end face of the side plate, and a second grinding wheel which is rotatably arranged between the inner roller carrier and the outer roller carrier. When the connecting shaft is not driven, the second grinding wheel can be separated from the outer roller carrier through the outer connecting device, and then the second grinding wheel is separated from the connecting shaft through the inner connecting device, so that the second grinding wheel is detached from the inner roller carrier, the outer roller carrier, the side plate and the connecting shaft, and a new second grinding wheel can be replaced conveniently; the grinding quality and efficiency of the fireproof plate cannot be reduced; when the second grinding wheel is installed on the inner roller carrier, the outer roller
