The main component of a single stamping press is a streamlined body, which is cast as a whole. It has a main shaft connected with three heart-shaped cams. The right end of the rotating press shaft is equipped with a flywheel, and the rotating press is equipped with a movable handle for manual adjustment. The left end of the shaft is equipped with a driven gear and a motor, which is transmitted from the V-belt to the small gear to the driven gear through a pulley, driving the main shaft. The various cams drive the connecting rod, that is, different lifting movements.
The main working process of the rotary tablet press and single stamping tablet press is divided into: A. Filling; B. Stamping forming; C. Produce or film. The three programs are performed continuously, and each program can be adjusted to meet the manufacturing needs of various components and tablets.
The DYP-1.5T single stamping machine has the advantages of small size, light weight, beautiful appearance, compact structure, easy operation, wide application, and low price. In the absence of power, the rotary tablet press can be manually operated by hand. When punching various components and other tablets, simply replace the appropriate die to obtain the desired shape.
During the testing and trial operation of the forced feeding system, some issues were discovered with the rotary tablet press, and further analysis is now being conducted.
(1) The problem of powder leakage and throwing in the forced feeding system is mainly caused by the loose fitting of the connecting parts between the hopper and the forced feeder during the pressing process, as there are small powder components in the materials of the pharmaceutical factory; Powder throwing is mainly caused by the loose fit between the forced feeder and the turntable plane. To solve these problems, it depends on the manufacturing process of the manufacturer to ensure. Therefore, when processing these key components, equipment, fixtures, tools, and scientific processes are necessary to ensure their processing accuracy.
(2) The analysis of the weight difference of tablets has been described above. Here is only a small conclusion: there are many factors that affect the weight difference of tablets. As for the forced feeding system, there are two requirements for it: first, it does not change the original state of the material, and second, it must have good fluidity to meet the requirements of the filling amount.
(3) There are three factors that affect the disintegration of tablets: first, the composition of the material; The second is the state of the material, and the rotary tablet press mainly refers to density, particle size, etc; The third is the pressure of suppression. In our experimental process, we found that under the same three factors, the disintegration of tablets filled and pressed by natural feeding system and forced feeding system were different. The disintegration of tablets filled and pressed by natural feeding system met the requirements, while the disintegration of tablets filled and pressed by forced feeding system did not meet the requirements. In addition, with the same forced feeding system, the disintegration of tablets produced by different models also varies. After analysis, the main reason is that during the process of filling the material with a forced feeder, the rotation of the impeller in the closed material chamber changes the original state of the material, resulting in an increase in fine powder in the material, ultimately leading to different degrees of disintegration. The more fine powder there is, the longer the disintegration degree of the rotary tablet press, and the less fine powder there is, and the shorter the disintegration degree. So, here, it is reminded that when designing this component, designers should not only meet the requirements of ordinary materials, but also design for different materials of the customer.
