AI Technical Summary
Existing drug filling machines lack an automatic leveling structure, resulting in uneven distribution of drugs in capsules. Furthermore, granular drugs are prone to agglomeration due to friction and static electricity, affecting dosage accuracy and filling efficiency.
An automatic scraping structure and a vibration filling structure were designed. The scraper leveled the height of the medicine and the vibration prevented the particles from agglomerating, ensuring that the medicine was on the same horizontal plane and smoothly entered the capsule.
This achieves uniform distribution and accurate dosage of the drug within the capsule, improves filling efficiency, and ensures drug quality and efficacy.
