Embodiment 1
[0038] Embodiment 1, tablet press machine, such as Figure 1-2 As shown, it includes a base 1 , a tablet press body 4 , a feeding device 8 , an intermediate part 9 and a pressing device 12 .
[0039] A first fixed wall 2 and a second fixed wall 3 are installed on the upper surface of the base 1, the first fixed wall 2 and the second fixed wall 3 are arranged in parallel, and the tops of the first fixed wall 2 and the second fixed wall 3 are respectively provided with a second fixed wall facing each other. A fixed plate 201 and a second fixed plate 301 . The base 1 , the first fixed wall 2 , the second fixed wall 3 , the first fixed plate 201 and the second fixed plate 301 enclose the installation channel 101 . The main body 4 of the tablet press is installed in the installation channel 101 and can slide freely therein.
[0040] The length of the first fixed wall 2 is greater than that of the second fixed wall 3 , and the first ends of the first fixed wall 2 and the second fi...

The invention provides a tablet press that comprises a base, a tablet press main body, a feeding device, a middle part and a pressing device, wherein a first fixing wall and a second fixing wall are mounted on the upper surface of the base, the first fixing wall and the second fixing wall are arranged in parallel, and a first fixing plate and a second fixing plate are oppositely arranged at the tops of the first fixing wall and the second fixing wall correspondingly. The invention also provides a tableting method. In the tableting method, after raw material powder is extruded into medicine tablets, the medicine tablets are stored the medicine tablets in a closed discharge chute (a first discharge plate blocks the bottom of a pressing pipe) all the time, so that the medicine tablets are kept in a closed state, and meanwhile, formation of other medicine tablets is not hindered; in the process of repeatedly preparing the medicine tablets, the discharge chute is in a closed state, so thatthe quality of the medicine tablets can be effectively guaranteed; and when the medicine tablets need to be used, a second discharging plate can be moved by an external motor and the like, so that thedischarge chute is moved out of a discharge channel, and the medicine tablets in the discharge channel can be taken out.
Description
technical field [0001] The invention relates to a tablet pressing machine and a tablet pressing method, in particular to a tablet pressing machine and a tablet pressing method for producing pharmaceutical tablets. Background technique [0002] Large scale production of pharmaceutical tablets usually involves the use of tablet punches which are used to compact a quantity of powder located in a mould. The powder in the die is held between opposing punches that move together a predetermined travel distance to produce a tablet of controlled thickness within a die of known geometry. This allows the formation of tablets with a known or determinable density depending on the geometry of the die and the volume of powder used, but does not allow direct control of the forces exerted on the tablet during compression. [0003] While smaller scale tablet presses are commercially available which are generally suitable for batch production, such equipment usually mimics the cyclic rotation...
