The invention provides a counting packaging device and a counting packaging method. The counting packaging device comprises a feeder, a feeding rail, a sensor, a counter, a receiving box, a receiving box rotating device, and a stopper, wherein the stopper comprises a magnetic switch and an iron sheet; one end of the iron sheet is connected with the magnetic switch and the other end of the iron sheet is close to the feeding rail and positioned under the feeding rail; a through hole is formed on one side of the feeding rail close to the receiving box; and the iron sheet enters or exits from the through hole from the bottom of the feeding rail by controlling the magnetic switch. Due to the adoption of the counting packaging device and the counting packaging method, products which are subjected to the independent packing process can be automatically counted and packaged according to the packaging number, and the number of automatic packaging is accurate. Therefore, the time and labor are saved, the packaging qualification rate is improved, and the production cost is reduced.
