A multi-station periodic type automatic hard capsule internal sealing device and method

Abstract

The invention belongs to the field of capsule sealing, and discloses a multi-station periodic type automatic hard capsule internal sealing device and method, which includes a capsule processing mechanism, a feeding mechanism and a drying mechanism. The capsule processing mechanism has a feeding station, The sealing liquid micro-spray station and the capsule discharge station include a rotary base that can rotate horizontally around its own axis and a plurality of carrier components evenly distributed on the rotary base. The carrier components are used to accommodate multiple capsules to be sealed. And spray the sealing liquid to the position where the capsule is to be sealed, and a pusher assembly is also set on the capsule discharge station; the feeding mechanism is located at the feeding station of the capsule processing mechanism, and is used to periodically and directionally transport the capsule to be sealed to the capsule for processing In the mechanism; the drying mechanism is located on the side of the pushing assembly, and is used for drying the sealed capsules discharged from the carrier assembly. The invention can realize the multi-station sealing operation of the capsule, and has the advantages of simple structure, high sealing efficiency, convenient operation and the like.

Description

technical field [0001] The invention belongs to the field of capsule sealing, and more specifically relates to a multi-station period type automatic hard capsule internal sealing device and method. Background technique [0002] Hard capsules are one of the important dosage forms for oral administration. Capsules need to be sealed after filling. If the capsules are not sealed, there will be changes in the capsule content, excessive water content and leakage during the packaging, storage, transportation, sales and application of the capsules. And other problems seriously affect the quality of capsules. Simultaneously, there is also a certain amount of fake and inferior products of unsealed capsules in the existing market, so hard capsule sealing technology has received extensive attention. [0003] At present, there are some technical solutions for the sealing of hard capsules. For example, patent CN101528182A discloses a device for sealing hard-shell capsules with coaxial co...

Problems solved by technology

[0002] Hard capsules are one of the important dosage forms for oral administration. Capsules need to be sealed after filling. If the capsules are not sealed, there will be changes in the capsule content, excessive water content and leakage during the packaging, storage, transportation, sales and application of the capsules. and other problems seriously affect the quality of capsules

At the same time, there are a certain amount of fake and inferior products of unsealed capsules in the existing market, so hard capsule sealing technology has received extensive attention

[0003] At present, there are some technical solutions for the sealing of hard capsules. For example, patent CN101528182A discloses a device for sealing hard-shell capsules with coaxial components. However, during the sealing operation of the sealing equipment, the capsule is in a horizontal state at the sealing station. This arrangement is not conducive to the sealing liquid entering the position to be sealed of the capsule. It is necessary to set nozzles with different arrangement directions, which greatly increases the design difficulty. The carrier assembly rotates around the horizontal axis, and the capsules are arranged in different positions at different stations. It is necessary to set a bias plate and a handling rod at each station to prevent the capsule from falling and ejecting the capsule, thus resulting in a sealing device structure very complicated
