Problems solved by technology

[0008] However, since the above-mentioned patents and publications are only in a preliminary research stage for the micro-control technology of powder, the above-mentioned parameters disclosed by it are only a rough and broad range, which are only suitable for laboratory experiments, and cannot be further investigated. Research
Due to the different physical properties of various powders, it has been found through research that the above design parameters are not only incomplete, but also cannot truly and well realize various powders, especially fine particles such as pharmaceuticals and poor fluidity, easy to agglomerate Micro-filling control of high-viscosity powder

Embodiment Construction

[0032] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0033] The pharmaceutical powder micro-filling machine of the present invention is as figure 2 As shown, it mainly includes a fuselage 100 , a precision displacement platform 101 disposed in the fuselage 100 , a filling platform 102 , and a filling nozzle 103 . Wherein, the filling nozzle 103 is arranged on the filling platform 102, and can move relative positions through the precision displacement platform 101 (the filling platform 102 can be fixed, the filling nozzle 103 can be moved, or the filling nozzle 103 can be fixed, and the filling Two ways of moving the filling platform 102) are used to fill the filling objects such as capsules and vesicles on the filling platform 102 below it to fill the drug powder. The filling nozzle 103 may include a nozzle housing 10, a filling flow channel 11 arranged in the nozzle housing 1...

Abstract

The invention discloses a drug powder trace filling machine which comprises a machine body, a precision displacement platform arranged in the machine body, a filling platform and a filling spraying nozzle, wherein the filling spraying nozzle comprises a filling runner and a vibration source. By perfection of key parameters and a specific parameter range in the whole runner design, design of various mounting structures for the vibration source and the filling runner, and computer control, the drug powder trace filling machine realizes precision quantification of trace filling of powder; and furthermore, by research on runner materials, the flowing speed of the powder in the runner is more stable, and the trace filling can be controlled more precisely and effectively.

Description

technical field [0001] The present invention relates to powder filling equipment, more specifically, relates to a medicine powder micro-filling machine. Background technique [0002] In the pharmaceutical industry, powder materials as raw materials, intermediates, and final products are involved in all aspects of drug development and production. In order to improve the biopharmaceutical efficacy of drugs and the human body's absorption of poorly water-soluble drugs, the particle size of powder used in pharmaceutical preparations is usually as low as micron or nanometer. However, this kind of fine powder material will show very poor fluidity, which has caused great operational technical difficulties and waste of raw materials for drug development and production. Among them, the R&D and production of respiratory dry powder inhalation medicaments are an effective means to treat asthma, chronic obstructive pneumonia and other lung diseases, and their research and development an...
