Production mold for double-layer enteric hollow capsule

Abstract

The invention discloses a production mold for a double-layer enteric hollow capsule, and belongs to the field of capsule production equipment. The mold is formed by splicing two identical first components, first forming portions and second forming portions in the first components are matched to form an outer capsule shell, the second forming portions and third forming portions are matched to form an inner capsule shell, and the inner capsule shell and the outer capsule shell are connected through a connecting hole in the mold. After the mold is spliced well, glue injection is carried out through a glue solution pipeline and a pipe opening in an upper cover plate, drying treatment is carried out, and the inner capsule shell and the outer capsule shell which are fixedly connected together can be obtained. After the mold is separated, the manufactured double-layer capsule shells are taken down, medicine powder is added into the inner capsule shell, the two double-layer capsule shells are spliced, and the double-layer enteric hollow capsule can be obtained. Compared with a traditional enteric capsule manufacturing method, by means of the mold, the situation that the medicine powder is processed into pellets for filling is avoided, the medicine powder is directly added into the inner capsule shell, then the two double-layer capsule shells are spliced, needed medicine can be obtained, the manufacturing process is easy and convenient, and processing efficiency is high.

Description

technical field [0001] The invention relates to a production mold, in particular to a production mold for double-layer enteric-coated hollow capsules, belonging to the field of capsule production equipment. Background technique [0002] The preparation of traditional capsules includes processes such as gluing, drying, and degumming. The mold body on the rubber plate is immersed in the glue solution and then dried on the drying line, and then transferred from the drying line to the degumming machine. Pull out the dried capsules one by one, the used capsule mold body is cylindrical, the head of the mold body is hemispherical, and there is an annular groove near the head of the mold body. The capsule will form a protruding ring near the bottom of its inner cavity, which is used for A and B capsules to be locked together after being fitted, so that the A and B capsules are not easy to come out after being fitted, and the medicine powder will not fall out of the capsule.

AI Technical Summary

Problems solved by technology

[0003] This kind of mold is mainly used for the production of ordinary hollow capsules, and for double-layer enteric-coated hollow capsules, because the outside of the medicine needs to be wrapped with a layer of capsule wall shell to prevent gastric juice damage, the current commonly used method is to use acidic or alkaline The powder is processed into pellets or enteric-coated pellets and then filled into corresponding hollow capsules (capsule shells) or enteric-coated hollow capsules (capsule shells), which are separated from the inner wall of the capsule shell by the outer coating of the pellets. This method needs to make medicine powder into micropills first, and then put the micropills into capsules. The preparation process is cumbersome and the processing efficiency is low.
