A machine that puts granular or powdered material into a die hole and presses it into tablets by a punch is called a tablet press.
earlytablet pressConsisting of a pair of dies, the punch moves up and down to confine the granular material into flakes, the machine is called a single-punch tablet press, and will be developed into an electric flower basket tablet press in the future. The working principle of these two tablet presses is still one-way tablet compression based on manual compression, I .e. the downward stroke is fixed during tablet compression, and only the upward stroke moves to pressurize. Due to the inconsistent upper and lower forces, this tablet compression method causes uneven internal density of the tablet and is prone to cracking and other problems.
The shape of tablets compressed by tablet presses is mostly oblate at first, but later it will develop into shallow arcs and deep arcs on both sides of the upper and lower sides. This is due to the need of coating. With the development of special-shaped tablet presses, oval, triangle, rectangle, square, diamond, round and other tablets have appeared. In addition, with the continuous development of preparations, due to the requirements of compound preparations and time-release preparations, it needs to be completed on a special tablet press, so special tablets such as double-layer, three-layer, and core-coated tablets are made.
In view of this shortcoming of the one-way tablet press, a rotary multi-stroke two-way tablet press was born. This tablet press presses up and down while pressing evenly, so that the air in the drug particles has enough time to escape from the die hole. The uniformity of tablet density is improved and the fragmentation phenomenon is reduced. In addition, the invention also has the advantages of low vibration, low noise, low energy consumption, high efficiency, and accurate tablet weight.
The rotary tablet press is a machine that uses multiple molds evenly distributed on the turntable to perform circular lifting motion according to a certain trajectory, and constrains granular materials into tablets through the pressing wheel. The linear speed of the punch rotating with the turntable is ≥ The 60 m/min tablet press is called a high-speed rotary tablet press. This high-speed rotary tablet press has a forced feeding mechanism. The machine is controlled by PLC. It has the functions of automatically adjusting pressure, controlling tablet weight, removing waste tablets, printing data, and displaying fault shutdown. In addition to controlling the difference in tablet weight within a certain range Within, it can also automatically identify and eliminate quality problems such as missing corners and loose tablets.
