A pharmaceutical production capsule screening device

Abstract

The invention belongs to the field of pharmaceutical production, in particular to a capsule screening device for pharmaceutical production. The capsule screening device for pharmaceutical production comprises a support bottom plate, on which a vibration dispersion device, a distance increasing device and a wind screening device are sequentially fixed and installed The vibration dispersion device includes a vibration mechanism and a vibration plate. The vibration mechanism is fixedly installed on the upper end surface of the support base plate. The upper end of the vibration mechanism is fixedly installed with a vibration plate. The vibration dispersion device also includes an anti-blocking mechanism. The lower end of the vibration plate is provided with a material distribution device. The mechanism enables the present invention to separate the capsule and the capsule shell well, and at the same time, it can be adjusted for a variety of drug capsules.

Description

technical field [0001] The invention belongs to the field of pharmaceutical production, in particular to a capsule screening device for pharmaceutical production. Background technique [0002] Capsules are solid or liquid medicines that are wrapped on the surface of the medicines with polymer substances or copolymers to form translucent, closed microcapsules with a granular appearance. Usually capsules are usually made of two shells that are open at one end. The drug is encapsulated in it, but in the actual production process of capsules that encapsulate solid drug particles, there is a certain probability that an independent shell that is not allowed to snap and cause the solid drug particles to spill during the process of the shell snapping. These particles and shells Mixing with the capsule will affect the subsequent detection and packaging of the capsule, so it is necessary to sieve the shell and drug particles mixed into the capsule. [0003] Since the volume of the ma...

[0002] Capsules are solid or liquid drugs wrapped on the surface of the drug by polymers or copolymers to form translucent, closed microcapsules with a granular appearance. Usually, capsules are usually made of two shells that are open at one end. The drug is wrapped in it, but in the actual production process of the capsules that wrap the solid drug particles, there is a certain probability that there will be an independent shell that is not allowed to snap and cause the solid drug particles to spill during the shell snapping process. These particles and the shell Mixing with the capsules will affect the subsequent detection and packaging of the capsules, so it is necessary to screen out the shell and drug particles mixed into the capsules

[0003] Since the volume of the manufactured capsule and the shell of the capsule has not changed greatly, but its quality has a large difference, the capsule and the shell of the capsule can be screened by wind force, and the traditional wind screening device is screening In the process of separation, the mixing degree of the capsule and the shell of the capsule is relatively high, and it is easy to produce mutual blocking influence in the process of winnowing, resulting in insufficient screening. At the same time, in the process of preparing drugs, the types of drugs are different. The volume and weight of the capsule and the shell of the capsule will change, and the traditional winnowing and screening device cannot be adjusted for a variety of drug capsules to achieve a good screening effect
