Powder scraping device for capsule filling machine

Abstract

The invention discloses a powder scraping device for a capsule filling machine. The powder scraping device comprises a first scraping sheet and a second scraping sheet, the first scraping sheet and the second scraping sheet are located between a metering panel and a metal plate of the capsule filling machine, the metal plate is located above the metering panel, and the first scraping sheet and thesecond scraping sheet are fixed onto the metal plate; the position of the first scraping sheet corresponds to a first station on the upper right portion of the metering panel; the position of the second scraping sheet corresponds to the portion between a third station on the upper left portion of the metering panel and a fourth station on the lower left portion of the metering panel. The powder scraping device is particularly suitable for powder capsule filling with excessively thick metering panels, and the problem of large difference of filling quantity can be solved; after capsules are filled with powder, the powder cannot be in a column shape, or the column-shape density is low, and disintegration and releasing of the capsules cannot be delayed; for low-dose filling, a powder bed canbe well scraped to be flat and evenly dispersed into filling holes of the metering panel so that stable filling quantity can be maintained; the powder scraping device is large in superficial area andlarge in powder scraping intensity, and can reduce the layering risk of the powder in the powder bed and the over-lubricating risk after magnesium stearate is added.

Description

technical field [0001] The invention relates to capsule filling equipment in the field of oral solid preparations, in particular to direct filling of capsule powder in the field of oral solid preparations, and in particular to a powder scraping device for a capsule filling machine. Background technique [0002] In the current pharmaceutical field, more and more small-molecule compounds are synthesized, screened, and modified in order to develop active molecules with high affinity and efficacy for the target, which has become the most important problem that new drug development scientists need to solve . In order to make these small molecular compounds permeate the biological semipermeable membrane of the human body better, and at the same time have acceptable water solubility, the functional groups in the molecules are continuously optimized, and the particle size of the physical form is also micronized to several Tens of microns or even hundreds of nanometers, which leads ...
