Hard empty capsule functional coating device and film coating method thereof

Abstract

The invention discloses a hard empty capsule functional film coating device and a film coating method thereof. The hard empty capsule functional film coating device comprises a liquid storage tank and a liquid dipping cam arranged above the liquid storage tank, the liquid dipping cam is in rotation fit with the liquid storage tank through a first rotating shaft, one end of the first rotating shaft is coaxially connected with a driving part, and the liquid dipping cam is in concave-convex rolling fit with a liquid coating concave wheel; and the liquid coating concave wheel is in rotation fit with the liquid storage tank through a second rotating shaft, the two ends of the liquid coating concave wheel are provided with annular bayonets matched with capsule molds respectively, the annular bayonets are in rolling fit with the capsule molds, and the capsule molds are in movable fit with a conveying mechanism. According to the method, the film coating device is adopted, a hinge is driven by a rotating gear to conduct transmission, the procedures of finishing, film coating, drying and demolding are conducted, and functional film coating is achieved. By means of the hard empty capsule functional film coating device and the film coating method, in a closed environment, volatilization of inorganic liquid is reduced, the concentration of functional liquid is guaranteed, the production safety is greatly improved, meanwhile, capsule semi-finished products are evenly coated, it is guaranteed that contents reach in a targeted manner, compound film coating can be achieved, and more requirements of products are met.

Description

technical field [0001] The invention belongs to the field of capsule production equipment, and in particular relates to a functional film coating device for hard hollow capsules and a film coating method thereof. [0002] technical background [0003] At present, the filling content of hollow capsules is developing rapidly, and the requirements are various. For hard hollow capsules, the requirements are varied, and the quality requirements are also increasing. Most of the daily content intake ingredients are usually digested and absorbed in the stomach through gastric acid, but some drugs need to be dissolved and absorbed in the intestinal tract. At this time, acid-resistant capsules are needed to fill the packaging content. [0004] There is only one acid-resistant product on the market that improves the functionality of hard hollow capsules, commonly known as enteric-coated capsules. Usually, the outsourcing process is used to complete the production. Before the convention...
