The rotary tablet press is currently a widely used multi punch press in production. Although its models are different, the pressing mechanism and principle are basically the same, mainly composed of a power part, a transmission part, and a working part. The power part is powered by an electric motor, and the first stage of transmission is the belt pulley, while the second stage is the worm gear that drives the tablet press machine (also known as the middle plate).
　　
The work includes: a machine for installing punch dies, a pressure wheel, a sheet weight regulator, a pressure regulator, a feeding hopper, a powder feeder, a vacuum cleaner, and a protective loading capacity. The machine is installed on the central axis of the machine base, and the upper layer of the machine is an upper punch turntable. The upper punch can be inserted into this turntable for lifting and lowering; The middle is a fixed die disc, forming a turntable with multiple die holes; The lower layer is the down punch turntable, which is inserted into this turntable and can be raised and lowered along the down punch track; Above the upper pressing wheel, there is a vertical upper pressing wheel, and below the machine, there is a corresponding lower pressing wheel. Every time the machine rotates, each upper pressing wheel is pressed down once, and the lower pressing wheel is pressed up once. At this time, the upper and lower punches squeeze the particles into tablets in the mold hole.
　　
The punch can rotate on its own during random table rotation (some types cannot rotate on their own). There is a fixed powder feeder on the mold plate, which is in close contact with it. The feeding hopper is located on top of it, and particles are added to the powder feeder. The mold plate rotates once, and each die passes through the scraper once, adding material and pressing it once.
　　
The pressure regulator is used to adjust the position of the lower pressure wheel. When the lower pressure wheel is raised, the distance between the upper and lower pressure wheels is shortened, and the distance between the upper and lower punch heads is also shortened, resulting in an increase in pressure; Conversely, the pressure decreases. The sheet weight adjuster is installed on the lower track and is a copper inclined plate that can adjust the height. It can make the downward punch rise or fall, thereby adjusting the filling amount of particles in the mold hole. Excess particles can be scraped off by a scraper to ensure accurate sheet weight.
