The drawing is a simplified form, and in all the embodiments, the drawing is not drawn according to precise dimensions.

First of all, please refer to Figures 1 to 6 at the same time. This authoring department provides a weighing and dispensing mechanism 10a, which includes: a processing unit 11; a setting unit 12, the setting unit 12 is electrically connected to the processing unit 11 Connected and used to set a subcontracting information, and send the subcontracting information to the processing unit 11; a weighing unit 13, the weighing unit 13 includes a medicine barrel 131 and a weighing platform 132, the medicine barrel 131 It has a medicine inlet and a medicine outlet for pouring a medicine powder in. The medicine inlet is arranged at the top of the medicine barrel 131, the medicine outlet is arranged at the connection part 1311 at the bottom of the medicine barrel 131, and the weighing platform 132 is combined with the medicine barrel 131 and electrically connected to the processing unit 11 for measuring the weight of the medicine powder stored in the medicine barrel 131, and generating at least one scale information to be sent to the processing unit 11; a drive The driving unit 14 is arranged under the medicine barrel 131. The driving unit 14 includes a first driving motor 141 and a first gear 142. The first driving motor 141 is electrically connected to the processing unit 11 and used for Drive the first gear 142 to rotate; a discharging unit 15, the discharging unit 15 includes a coupling 151 with a through hole 1511, a second gear 152 and a discharge rod 153, the coupling 151 is connected to the The part 1311 is combined and disposed above a medicine discharge port 16, the second gear 152 is disposed on the coupling member 151, and the second gear 152 is meshed with the first gear 142, and the discharge rod 153 is disposed In the medicine barrel 131, one end of the discharging rod 153 passes through the medicine outlet from the connecting portion 1311 to be coupled to the coupling member 151, and the end of the discharging rod 153 has a spiral part 1531 , So that the medicine powder can follow the thread of the spiral part 1531 to drive the medicine drop; and an arithmetic unit 17 which is electrically connected to the processing unit 11 to receive the sub-package information and the weighing scale information; wherein, Before dropping the medicine, the arithmetic unit 17 calculates the weight of the medicine powder for each sub-package according to the sub-package information and the weighing information, and sends a sub-package command to the processing unit 11, which is based on the sub-package information. The first drive motor 141 is commanded to drive the first gear 142, and then the second gear 152 drives the discharge rod 153, so that the medicine powder is squeezed from the medicine discharge port to the medicine discharge port 16 to discharge the medicine .

For example, the user first uses the setting unit 12 to set the sub-package information (such as the number of sub-packages 10) and pour the adjusted powder into the medicine barrel 131 of the weighing unit 13, and the weighing unit 13 The table 132 measures the weight of the powder in the medicine barrel 131 (total weight is 50 grams), and then the computing unit 17 calculates the weight of the powder in each sub-package (5 grams) based on the sub-package information and the weighing information, The arithmetic unit 17 transmits the sub-contracting instruction to the processing unit 11, so that the processing unit 11 controls the first drive motor 141 to drive the first gear 142 according to the sub-contracting instruction, and then drives the output by the second gear 152 The material rod 153 is used to squeeze the medicine powder from the medicine discharge port to the medicine discharge port 16 to discharge the medicine.
