Gas flow insertion pipe type powder filling machine

Abstract

The invention discloses a gas flow insertion pipe type powder filling machine comprising a buffer rotary table, an acceleration rotary table receiving all penicillin bottles from the buffer rotary table, a feed star wheel receiving all the penicillin bottles from the acceleration rotary table, a feed fan-shaped star wheel, a conveying net belt, a powder plate, a filling mechanism, a discharge fan-shaped star wheel and a pressing and plugging mechanism. The feed fan-shaped star wheel equally divides all the penicillin bottles from the feed star wheel into three sets and converts the continuous movement of the three sets of penicillin bottles into intermittent movement. The conveying net belt conveys the three sets of penicillin bottles to filling stations in an intermittent movement manner correspondingly. The powder plate is installed beside the filling stations and contains medicine powder. The filing mechanism sucks the medicine powder in the powder plate and fills the medicine powder in all the penicillin bottles on the filling stations. The discharge fan-shaped star wheel divides all the penicillin bottles, where filling is completed, from the conveying net belt into three sets, and converts the intermittent movement of the three sets of penicillin bottles into continuous movement. The pressing and plugging mechanism continuously presses and plugs all the penicillin bottles from the discharge fan-shaped star wheel. The gas flow insertion pipe type powder filling machine can effectively avoid contamination and improve the filling precision.

Description

technical field [0001] The invention relates to the field of pharmaceutical equipment, in particular to a powder filling machine. Background technique [0002] With the rapid development of the pharmaceutical industry, powder preparations are more and more valued by pharmaceutical manufacturers. Powder preparations have a series of advantages such as being more stable than aqueous injection preparations. At present, domestically, the intermittent rotation of the mechanical screw is mainly used to load the powder into vials, and abroad, the airflow wheel technology is mainly used for subpackaging. The mechanical screw subpackaging method makes the screw and the powder rub violently, and the worn metal particles enter the powder and easily cause pollution. In addition, due to the poor reproducibility of the precision of the screw processing and the number of revolutions of each rotation, the filling precision has a large fluctuation. However, due to the complex structure and...

Problems solved by technology

The mechanical screw subpackaging method makes the screw and the powder rub violently, and the worn metal particles enter the powder and easily cause pollution

In addition, due to the poor precision of screw processing and the poor reproducibility of the number of revolutions per rotation, the filling precision has a large fluctuation

However, due to the complex structure and high manufacturing cost of the airflow wheel type, it is inconvenient to maintain and clean, and there is also the risk of powder and metal wear

At this stage, the airflow intubation powder packaging technology is still in a blank state in China.
