Problems solved by technology

Existing single-punch tablet presses use the upper die and the lower die to extrude shaped tablets, and then need to adjust the tablet weight. The existing technology needs to be pressed first and then the tablet weight is adjusted, which has a certain impact on the shaped tablets. The waste of raw materials is caused by the first scraper dust removal, and the scattered powder cannot be reused. The second use of raw materials increases the weight of the tablet and increases the cost, and leads to poor final molding effect of the tablet.
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

Abstract

The invention discloses a single-punch type tablet machine. The single-punch type tablet machine comprises a pressing device, a feeding device and a collecting device. The pressing device comprises an upper punch, a middle die and a lower punch. The feeding device is located on the upper stream of the pressing device, a second curved material filling cavity for containing powder materials is formed in the feeding device, and the feeding device is driven by a power mechanism to horizontally move in a reciprocating mode. The powder materials are continuously filled into a first material filling cavity, and a material scrapping portion is formed on the side wall of the feeding device. The collecting device is located on the lower stream of the pressing device and comprises a tablet guiding drum and a tablet collecting box, wherein the tablet drum is used for accepting formed tablets and obliquely arranged, and the tablet device is used for collecting the formed tablets and located below the tablet guiding drum. According to the single-punch type tablet machine, through secondary forming, the tablet-weight qualification rate of the formed tablets is increased; the scattered materials and the adhered materials are collected through the colleting device, so that the utilization rate of the materials is increased; and the tablet weights of the prepared formed tablets consistently reach the standard, and the forming effect is good.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical equipment. More specifically, the present invention relates to a single-punch tablet press. Background technique [0002] The single-punch tablet press 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 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 single-punch tablet presses use the upper die and the lower die to extrude shaped tablets, and then need to adjust the tablet weight. The existing technology needs to be pressed first and then the tablet weight is adjusted, which has a certain impact on the shaped tablets. The first-time scraper dust removal causes waste of raw materials, and the scattered p...
