Discuss the principle and operation steps of high-speed tablet press

High-speed tablet press machine is a kind of powder forming machine that uses working pressure. Driven by the rotation of the pressure plate fixed on the main shaft of the machine tool, the punching needle is controlled by the left and right slide rails in the vertical position. According to the thickness of the pressure plate, the position of the pressure plate can be adjusted according to the pressure plate readjustment mechanism, and then raised or lowered The distance between the left and right punching pins, and then control the thickness of the pin. The basic working principle of the high-speed tablet press machine is: fixed on the main shaft of the machine tool, the rotation of the main shaft pushes the working pressure at the bottom end, the perforated holes on the pressure plate are guided by the rising and the downward guiding pressure plate rotates, and the main shaft of the machine tool under the tube bundle is all Each set of rollers has its own prestressed tensioning wheel and main roller. When the two sides of the punching needle rotate to the upper and lower rollers, the prestressed tensioning wheel and the main pressure wheel are respectively fixed on the upper and lower housings. On, increase the force successively to make the powder shape. The operation process of the high-speed tablet press includes the whole process of feeding, quantification, prestressed tension, main press forming, and plastic sheet. The left and right punching rods are pushed and separated from left to right along the upper and lower slide rails. When the hole feeds a part of the movement, the piston rod moves upward to avoid the coaxial cable, and the hole moves downward according to the downward direction. At this stage, the punch and the inner hole of the mold form a cavity, which promotes the mixing of raw materials and impeller. 1. When the camshaft fills the inner cavity, it moves upwards slowly, while other raw materials will be sent out in the die hole and enter the quantitative section. In the quantitative part, the remaining material is peeled off to ensure that each middle die hole is filled with the same amount of material. In order to prevent the items in the die hole from being thrown out, the pressure plate is refitted after the quantitative scraper. Cover the maintenance slide rails and pull down the lower punching rod, and the upper punching rod moves downward according to the action of depressing the camshaft, the middle die hole moves out the pin, the upper punching hole enters the middle die hole, and the pressing is completed piece. When the punching rod passes through the camshaft, the upper punching rod moves upwards, and the lower punching rod pushes upwards, and the pressed pills are released, and the pills enter the tablet pressing machine through the plate partition, and all the tablets are pressed The whole process is carried out. Each revolution of the cold stamping die, each set of dies can carry out the whole tableting process of the high-speed tablet press twice.
