Empty capsule shell manufacturing and forming method

Abstract

The invention provides an empty capsule shell manufacturing and forming method. According to the empty capsule shell manufacturing and forming method, an empty capsule shell manufacturing and forming device is adopted in the empty capsule shell manufacturing and forming method; the empty capsule shell manufacturing and forming device comprises a processing cylinder, a filtering unit and an execution unit; and the filtering unit is arranged on the lower side of the inner wall of the processing cylinder, and the execution unit is mounted at the upper end of the processing cylinder. The empty capsule shell manufacturing and forming method can solve the following problems: 1, when a traditional capsule glue solution is filtered, the glue solution is mostly poured into the filtering device and then is filtered in the filtering device under the action of gravity, so that the filtering effect is poor, and the filtering time is prolonged; and 2, as a discharge port of the filtering device is mostly sealed in a threaded fit manner, the capsule glue solution is easy to adhere to a threaded groove of the discharge port during discharging, the sealing effect is poor, and the capsule glue solution is easy to flow out from the discharge port.

Description

technical field [0001] The invention relates to the technical field of hollow capsule shells, in particular to a method for manufacturing a hollow capsule shell. Background technique [0002] Capsules are mainly used to wrap powders or granules that are irritating to the esophagus and gastric mucosa, or medicines that have a bad taste, are easy to volatilize, are easily decomposed by saliva in the mouth, and are easy to be inhaled into the trachea; Hollow capsules made of materials such as gelatin, cellulose, polysaccharides, etc. When the shell of the capsule is produced and processed, the glue solution for making the capsule is first prepared, and during the preparation process, debris is easy to remain inside the glue solution, so The glue needs to be filtered to ensure the quality of the capsule shell in the later stage. [0003] However, the following problems exist in the filtration process of the capsule glue at present: 1. When the traditional capsule glue is filter...

AI Technical Summary

Problems solved by technology

[0003] However, the following problems exist in the filtration process of the capsule glue at present: 1. When the traditional capsule glue is filtered, the glue is poured into the filter device, and then it is filtered in the filter device under the action of gravity Processing, so the filtering effect is poor and the filtering time is increased;

[0004] 2. Since the discharge port of the filter device is mostly closed by thread fit, the capsule glue is easy to adhere to the thread groove of the discharge port when discharging, and the sealing effect is poor, and the capsule glue is easy to flow out of the discharge port. outflow
