[0001] The utility model relates to the technical field of pharmaceuticals, in particular to a medicine subpackaging device. Background Art

[0002] With the improvement of pharmaceutical technology, most liquid medicines are made by mechanical equipment. Common pharmaceutical equipment includes medicine filling machines, which are used to fill liquid medicines. The main machine of the filling machine is equipped with a liquid tank, which is connected to the filling nozzle through a guide pipe. The guide pipe is equipped with a stop valve. The medicine bottles are transported in sequence on the conveyor belt. When they reach the filling nozzle, the stop valve opens and the medicine is filled into the medicine bottle to complete the filling.

[0003] In the prior art, for example, a preparation dispensing device disclosed in the patent application number CN202321870056.3 measures the medicine quantitatively through a dispensing quantitative plate arranged in a bottom dispensing tank, and the excess medicine flows out from the top of the dispensing quantitative plate, so that each group of medicine liquid is consistent, thereby achieving uniform dispensing of the medicine.

[0004] The height of the prior art dispensing quantitative plate is fixed, so it can only dispense a fixed amount of medicine. However, in reality, the amount of each medicine will change with the improvement of the medicine. If the amount of medicine changes, the appropriate dispensing quantitative plate must be replaced before dispensing the medicine. This process is time-consuming and labor-intensive. If a new dispensing device is directly replaced, it will cause a waste of materials. Utility Model Content

[0005] In order to solve at least one of the technical problems mentioned in the background technology, the purpose of the present utility model is to provide a medicine packaging equipment to solve the problem in the prior art that the medicine packaging quantity must be adjusted by replacing the packaging quantitative plate, thereby improving the adaptability of the packaging equipment.
