AI Technical Summary
The liquidity of the drug powder is insufficient during the filling process, resulting in the inability to disperse evenly within the powder filling ring, which leads to uneven filling amounts, and even no medicinal powder can be filled on the mold holes at the edge of the metering plate.
A powder dispersion device for capsule filling machines is designed, including a metering disk and a mold frame. A feeder is fixedly arranged on the metering disk. At least three sets of baffles are arranged on one side of the metering disk. One end face of the baffle is provided with a 45-degree slope guide angle. Through these structures, the powder is evenly opened and sent to the mold hole of the metering disk edge, and the powder height is scraped to the appropriate position through the scraper structure to ensure flatness and uniform movement.
It effectively solves the problem of uneven filling caused by insufficient fluidity of the powder, ensures the uniform movement of the powder in the metering plate and the stability of the filling amount, and is especially suitable for filling powder materials with poor fluidity.
