Abstract

The invention relates to the technical field of tablet preparation, and discloses a tablet preparation device for avoiding tablet splitting. The tablet preparation device for avoiding the tablet splitting includes a material box and is characterized in that the interior of the material box is fixedly connected with a rotating shaft in a sleeving mode, the bottom end of the material box is fixedlyconnected with a conveying tube, the bottom of the conveying tube is fixedly connected with a feeding opening, the outside of the rotating shaft is fixedly connected with a connection disk in an inserted mode, the inside of the connection disk is fixedly connected with an electromagnet, a spring is movably connected to the bottom end of the connection disk, and is located on the outer side of theelectromagnet, a ball screw is movably connected to the inner part of a guide rail, the bottom end of the ball screw is fixedly connected with a male die, and the bottom end of the rotating shaft is rotatably connected with a female die seat. According to the tablet preparation device for avoiding the tablet splitting, magnetism is generated through the electromagnet to adsorb the guide rail, theconnecting disk and a fixing block are driven to rotate through the rotating shaft, thus the female die is transported above a male die, the ball screw is used in combination with the guide rail and the electromagnet in order to achieve the effects of sufficient pre-pressure and long extrusion time.

Description

technical field [0001] The invention relates to the technical field of tablet preparation, in particular to a tablet preparation device which avoids splitting. Background technique [0002] At present, the largest dosage form in the pharmaceutical market is the tablet, which has good stability and low cost. The tablet was developed on the basis of the use of pills. It originated in the 1840s. With the development and progress of tablet machinery technology, the production and application of tablets have been greatly developed. [0003] The development of tablet machinery technology has led to the mass production of tablets. During the mass production process, some tablets may crack due to mechanical reasons, resulting in economic losses. At present, in the process of pharmaceutical production, most of the pre-pressure is too small and the extrusion time is too short. The air in the punch and die cannot be removed during extrusion. When the gas is compressed, the powder will...
