Medicinal powder filling device of fully-automatic capsule filling machine

Abstract

The invention discloses a medicinal powder filling device of a fully-automatic capsule filling machine, which mainly comprises a cover plate, an isolation block, a filling rod and a metering disc, wherein the upper surface of the isolation block is closely contacted with the cover plate, so medicinal powder cannot enter the space between the isolation block and the cover plate; and when the filling rod passes through the cover plate and the isolation block and pushes the medicinal powder into a metering hole of the metering disc, no extra medicinal powder enters the metering hole; therefore, the precision of the charge amount is ensured.

Description

technical field [0001] The invention relates to the structure of a fully automatic hard capsule filling machine, in particular to the structure of the part of the fully automatic capsule filling machine responsible for filling medicine powder into the capsule. Background technique [0002] The drug capsule is divided into a capsule body and a capsule cap, the capsule body is partially filled with drug powder, and the capsule cap is installed at the mouth of the capsule body to form a closed capsule. The production of capsules by a fully automatic capsule filling machine generally goes through the process of separating the capsule body and cap-metering powder filling-capsule rejecting-capsule locking-finished product release-powder cleaning and other processes. In the above metering and powder filling process, the automatic capsule filling machine pushes the powder into the bottom of the metering disc through the filling rod, and then pulls out the filling rod to make the pow...

Problems solved by technology

[0003] figure 1 It is the structure of the metering powder loading part of the existing filling machine. The filling rod 1 passes through the cover plate 2 and the isolation block 3', pushes the powder to the bottom of the metering disc 4 and then pulls it out. This process will cause accumulation on the surface of the metering disc 4 A certain thickness of powder; with the rotation of the metering disc, the spacer will scrape the powder on the surface of the metering disc

but figure 1 In the structure, there is a certain gap between the upper surface of the spacer 3' and the cover plate 2, and the powder accumulated on the metering disc can enter the gap between the cover plate and the spacer, and with the movement of the filling rod 1 Refilling to the bottom of the metering disc, which affects the accuracy of capsule filling

Moreover, the thickness of the existing isolation block is relatively large. When the isolation block scrapes off the powder on the metering plate, the fluidity of the powder on the metering plate will be affected, which will also affect the accuracy of the powder charge.
