Briefly describe the application of automatic vacuum feeder in capsule filling machine

At present, the proportion of hard capsule in the market of medicine and health care products is increasing day by day The capsule filling machine, as the basic equipment of its production, will be more widely used, and people's requirements for its application will also be improved Although the manufacturing and technology of the domestic capsule filling machine is basically mature, the drawback of the United States and China is its feeding mode Chinese people also deal with it through a variety of feeding modes In the face of a variety of feeding modes and national conditions, how will people choose the feeding mode? Since the large-scale application of capsule filling machine to produce hard capsule in China in 1980s, the feeding mode has gone through several processes: from the original manual ladder dumping to conveyor belt conveying, from barrel lifting to positive pressure conveying, from vacuum conveying to automatic vacuum conveying, and also cross layer pneumatic self weight conveying The development of these processes shows the progress of their loading methods with the development of the times 　　 At present, in the production of solid preparations in China, except a few of the capsule filling machines still use manual ladder or other methods of feeding, the automatic vacuum feeding machine and bucket elevator are mainly used for feeding These two methods have their own advantages With the maturity of the automatic vacuum feeding machine technology and the structural limitation of the workshop under construction in the near future, the automatic vacuum feeding machine will show a practical side However, the purpose of the two feeding methods is to overcome the imperfections of the manual ladder feeding method: (1) because the mixed powder needs to have a turnover bucket to be placed and transported to the capsule filling process, the original manual ladder feeding method, its loading and pouring process will cause dust flying, pollute the site, equipment, operators, etc., and clean the air and protect the environment Health of students and personnel is also extremely adverse At the same time, the production site and production equipment are not easy to clean The filtration device of purification system is easily blocked or damaged, resulting in poor filtration effect and reduction of purification level (2) In the manual ladder pouring mode, the labor intensity of operators engaged in transportation and ladder pouring is also very large.
