Tablet machine

Abstract

The invention discloses a tablet machine. The tablet machine comprises a pressing device, a charging device and a collection device, wherein the pressing device comprises an upper punch pin, a middle die and a lower punch pin; the charging device is located at the upstream part of the pressing device, a second curved filler cavity used for accommodating a powdery material is arranged in the charging device, the charging device carries out horizontal to-and-fro movement under the driving of a power mechanism to continuously fill a first filler cavity with the powdery material, and a scraping part is formed on the sidewall of the charging device; and the collection device is located at the downstream part of the pressing device, and comprises a tablet guide barrel used for bearing formed tablets and arranged slantwise, and a tablet collection box located below the tablet guide barrel and used for collecting the formed tablets. According to the tablet machine disclosed by the invention, the tablet weight qualification rate of the formed tablets is increased through secondary forming, and scattered materials and attached materials are collected through the collection device, so that the utilization rate of the materials is increased; and the tablet weights of the prepared formed tablets uniformly reach the standards, and a good forming effect is achieved.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical equipment. More specifically, the present invention relates to a tablet press. Background technique [0002] The tablet press machine is a machine that presses powdery materials into tablets through a mold to meet the requirements of the pharmaceutical industry for pressing various Chinese and Western medicine preparations and the health care product industry for pressing various similar products. Tablets are usually made by compressing them into tablets by a tablet press, and then coating according to actual needs. Existing tablet presses use the upper die and the lower die to extrude formed tablets, and then need to adjust the tablet weight. The existing technology needs to be pressed and then adjusted, which will have a certain impact on the formed tablets. Dust removal causes waste of raw materials, scattered powder cannot be reused, secondary use of raw materials increases tablet wei...

AI Technical Summary

Problems solved by technology

Existing tablet presses use the upper die and the lower die to extrude formed tablets, and then need to adjust the tablet weight. The existing technology needs to be pressed and then adjusted, which will have a certain impact on the formed tablets. Dust removal causes waste of raw materials, scattered powder cannot be reused, secondary use of raw materials increases tablet weight, increases cost, and leads to poor final tablet molding effect

When the material to be pressed is a light and fine powder material, even if the material weighed by the meter reaches the tablet weight, due to the particularity of the material, the material is easily lost during the extrusion process, and the material cannot be evenly filled in the middle mold. The raised materials are scattered in the air, which makes it impossible to reach the preset weight range of the formed tablets. The compressed formed tablets are too light to be used. The unqualified tablets need to be re-crushed, mixed, and tableted again. The pass rate of tablet production lower
