Detailed ways

In order to introduce the technical solution of the present invention more clearly, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

As shown in Fig. 1 and Fig. 2, the rotary drug storage box used for the automatic drug subpackaging machine according to the present invention includes a casing 1, which is arranged inside the casing 1 and has a base 2 whose top surface is an inclined surface. The inclined counting tray 4 on the support 2, the tray 11 arranged between the inclined counting tray 4 and the support 2, the medicine storage box 6 that can be fixed on the casing 1, and the inclined The transmission mechanism 3 connected to the counting disc 4, the bottom surface 10 of the medicine storage box is provided with a hole communicating with the inside of the casing 1, the inclined counting disc 4 is provided with a medicine hole 7, and the base 2 A drug dropping channel 8 is provided on the upper and higher sides of the top surface, and a drug dropping hole 12 is provided on the tray 11 at a position corresponding to the drug dropping channel 8 provided on the machine base 2 .

In the present invention, the transmission mechanism 3 is located in the base 2 and is an Oldham coupling or a bevel gear transmission. The transmission mechanism 3 is powered by the power source of the medicine automatic subpackaging machine through the transmission input shaft 9, and uses the characteristics of the angle transmission of the cross coupling or the bevel gear transmission device to drive the inclined counting plate 4 clockwise. Or rotate counterclockwise, so that the inclined counting disc 4 forms an included angle with the horizontal plane, ensuring that each drug-carrying hole 7 can only take away one counted drug into the drug-dropping channel 8 when the inclined counting disc 4 rotates, The rest of the granules automatically fall in the casing 1 under the action of their own gravity. When the transmission mechanism 3 adopts a bevel gear transmission, the bevel gear transmission drives the inclined counting disk 4 to rotate counterclockwise, as shown in FIG. 3 . When the transmission mechanism 3 adopts a cross coupling, the cross coupling drives the inclined counting disk 4 to rotate clockwise, as shown in FIG. 4 .

In order to be suitable for medicine grains of different shapes, the medicine-carrying holes 7 on the inclined counting plate 4 are set as round holes, oblong holes or semicircular holes. At least two medicine-carrying holes 7 are arranged on each inclined counting plate 4, and several medicine-carrying holes 7 are evenly distributed on the inclined counting plate 4, as shown in Fig. 5 , Fig. 6 and Fig. 7 .
