摘要： A rotary tablet press comprises a press housing having bottom and top ends. A compression assembly in the press housing includes pressure roll assemblies. A drive housing extends outwardly from the top end of the press housing. A motor drive assembly is in the drive housing and comprises a turret motor rotationally driving a drive shaft extending downward from the turret motor, the drive shaft being mounted for axial movement along a vertical axis in the turret motor. A drive shaft control is operable to controllably raise and lower the drive shaft. A turret assembly is mounted to the press housing below the drive housing and about the vertical axis so that the pressure roll assemblies engage the turret assembly, the drive shaft engaging the turret assembly to rotate the turret assembly responsive to the drive shaft control lowering the drive shaft.

摘要： The rotary tablet press comprises a machine base assembly and detachable module. Granulation is fed into the module from the hopper and travels into the feeder chamber. The base assembly comprises motorized pressure roll assemblies and a turret drive assembly. The detachable module comprises a module base, turret base, turret, cam body, cams, feeder, tablet discharge chute, hopper, upper enclosure, and guard doors. The rotary turret comprises upper punches, dies, and lower punches. As the turret rotates, the dies move underneath the feeder chamber. The rotary feeder paddles move the granulation and assist with feeding powder to the dies. Punches travel along cam tracks as the turret rotates and compresses the powder into a tablet when the punches contact the pressure rolls. An ejection cam pushes the lower punch in the upward direction and a take-off bar mounted just above the die table directs the tablet into a discharge chute. The detachable module is sealed by incorporating an upper enclosure.
