[0002] During the drug manufacturing process, raw materials are usually delivered in a quantitative manner to drug manufacturing equipment for drug preparation.

[0003] A Chinese patent with application publication number CN218908855U discloses a quantitative feeding mechanism for pharmaceutical raw materials. In the patent, the pharmaceutical raw materials flowing out of the hopper fall onto a conveyor belt A under the guidance of a guide plate A. The quantitative amount of the pharmaceutical raw materials is detected by a weighing sensor. When the quantitative amount of the pharmaceutical raw materials on the conveyor belt A meets the standard, the weighing sensor controls the linear electric push rod electric cylinder to retract the push rod, so that the guide plate A flips upward, seals the discharge port of the hopper, and controls the conveyor belt A to transport the pharmaceutical raw materials, thereby reducing the workload of the staff and improving work efficiency.

[0004] When using the above patent, we found that the device does not have the ability to stir the pharmaceutical raw materials, which causes the raw materials to easily agglomerate, which is not conducive to the discharge of the original medicine and greatly affects the processing efficiency of the pharmaceutical raw materials. Therefore, we proposed a quantitative feeding mechanism for pharmaceutical raw materials. Utility Model Content
