Variable-speed response capsule glue-dipping device and method

Abstract

The invention discloses a variable-speed response capsule glue-dipping device and method. A glue-dipping groove is improved and comprises an inner groove and an outer groove; under the action of a stirring rod at the opening at the bottom of the inner groove, a glue liquid springs out from bottom to top at the bottom of the inner groove so as to overflow into the outer groove and then enters the bottom of the inner groove from the outer groove for turnover, and the process is performed in a circulating and reciprocating manner to achieve the stirring effect; a second motor driving the stirring rod to rotate is matched with the operation of a glue-dipping cam driving device to perform high-speed rotation or low-speed rotation under the action of a variable-frequency controller; when the glue-dipping operation is stopped, the high-speed rotation is performed, thereby quickly and uniformly stirring the glue liquid; and when the glue-dipping operation is started, the stirring rod rotates at low speed so as to enable the glue-dipping liquid level and the glue liquid in the glue-dipping groove to be basically in a static state. Thus, the uniformity of glue films formed by glue dipping is better, and produced capsules have small difference in natural grain weight.

Description

technical field [0001] The invention relates to a glue dipping device and a glue dipping method for a capsule mold, in particular to a variable speed response capsule glue dipping device and method. Background technique [0002] Capsules are one of the oldest dosage forms of medicines. They originated in ancient Egypt and account for about one-third of all dosage forms in the pharmaceutical industry. Therefore, the hollow capsules used in capsules are one of the important packaging materials in the pharmaceutical industry. The hollow capsule is formed by fitting a body and a cap. The capsule production process is composed of glue making, production, lighting, printing, sterilization, packaging and other processes. The production process has the following steps to complete: dipping glue, drying, demoulding, cutting, and fitting, so that the whole process of capsule production is completed, and hollow capsules that meet industry standards can be produced.

Problems solved by technology

[0005] When dipping the glue, the glue is usually placed in the dipping tank, and constant stirring is required to maintain the uniformity of the glue. However, due to the frequency of stirring for each person, the grasp of the uniformity of the glue is different, so in When dipping in the glue, it is easy to produce uneven thickness of the glue film, so that the difference in grain weight is too large

Since the difference in the grain weight of the capsule will affect the amount of medicine, the pharmaceutical factory has strict requirements on the grain weight difference of the hollow capsule. Due to the limitation of the structure of the dipping device and the dipping process, it is also difficult to control the grain weight difference in the production of hollow capsules.
