Description

A special dust removal device for a pharmaceutical tablet press

technical field

The utility model relates to the technical field of pharmaceuticals, in particular to a special dust removal device for a pharmaceutical tablet press.

Background technique

Tablet presses are mainly used for tablet process research in the pharmaceutical industry. The tablet press is an automatic continuous production equipment for compressing the granules into circular, special-shaped and sheet-like objects with characters, symbols and graphics with a diameter of not more than 13mm. The tablet shape pressed by the tablet press is mostly oblate at first, and later developed into shallow arc and deep arc on the upper and lower sides, which is for the needs of coating. With the development of special-shaped tablet presses, oval, triangular, oval, square, diamond, annular and other tablets are produced. In addition, with the continuous development of preparations, due to the requirements of compound preparations and timed-release preparations, special tablets such as double-layer, triple-layer, and core-coated are made, which all need to be completed on a special tablet press.

At present, in the process of compressing powdered drugs into tablets, due to factors such as raw material particles for tableting, the gap between the feeder of the tableting machine and the feeding platform, the feeder is exposed outside the tableting solid, and the gap between the die and the die hole For various reasons such as size, powder will appear on the surface of the compressed tablet. In order to remove the powder on the surface of the tablet, the following measures are often used. The method of wiping with a rag is inefficient, and static electricity will be generated during the wiping process, resulting in unclean dust removal. The method of compressed air removal is used, although it can be cleaned up , but it will cause the dust to spread into the air and cause the dust to fly to form secondary pollution. Therefore, it is necessary to improve.
