[0002] The concept of "food and medicine sharing the same origin" refers to substances that can be consumed as food and also have medicinal value. They are widely used in traditional medicine to prevent or assist in the treatment of diseases. This concept originates from the theory of traditional Chinese medicine and emphasizes the synergistic effect of food and medicine, and the balance of the body through daily diet.

[0003] Common food and medicine homologous substances include red dates, yams, and poria cocos. To make them convenient to eat, they are often ground into powder and packaged for sale. During packaging, automatic weighing equipment is needed to quantitatively package them. However, most common quantitative packaging equipment currently uses a single set of weighing equipment to directly fill and weigh the material. Since the powder is relatively light, the rapid discharge during packaging can easily cause large errors and affect the accuracy of packaging.

[0004] There is an urgent need for a precise quantitative packaging machine for food products that are both food and medicine to solve the technical defects mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a precise quantitative packaging machine for food products that are both food and medicine, so as to solve the problem of inconvenient precise quantitative measurement mentioned in the background art.
