The principle of the invention is as follows: when in use, the medicine bag moves between the support plate 3 and the curved surface pressing block 2. Under the action of the compression spring 6, the protrusion 201 of the curved pressing block 2 is ejected out to one side of the supporting plate 3, so that the two sides of the medicine package are respectively pressed by the supporting plate 3 and the protrusion 201. When the medicine package is filled with the medicine, the thickness of the medicine package is thicker, the medicine package ejects the bulge 201 to the side far away from the supporting plate 3, the curved surface pressing block 2 rotates along the rotating shaft to reach the second position, and at the moment, the sensor 5 outputs a corresponding signal. The cartridge bag continues to move, when the cartridge bag is empty, the cartridge bag is small in thickness, at this moment, under the effect of compression spring 6, protrusion 201 is close to support plate 3, curved surface briquetting 2 rotates along the pivot, reaches first position, and sensor 5 outputs corresponding signal this moment.
