Rotary tablet press structure and working principle

Have ZP - rotary tablet press 5、ZP - 7,ZP - A variety of models such as 9, in line with the GMP standard, tabletting chamber which is completely separated from the drive mechanism, contact with the material of the surface of the parts adopt stainless steel material or special treatment, non-toxic decay resistance, tabletting room with transparent organic glass is closed, to prevent pollution. Everywhere a smooth surface, easy to handle. Rotary tablet function compressed into tablets ( The machine pressure range) And powder content ( More than 100 mesh) Not more than 10% of granular materials, applicable to suppress 4 ~ 12 mm round tablets. Small rotary tablet press is according to the production of automatic rotation, continuous tabletting tablet press the miniaturization of machine. Structure and working principle of rotary tablet press: 1 turntable structure: main execution of the turntable is the machine work pieces. There are upper and lower bearing components, spindle, rotary table and other major parts. Spindle support on the bearing, the worm gear pair transmission, spline connection, transmission shaft, make the turntable rotate. 2 rail agency: track is on track and the track of cylindrical CAM and CAM, is the upper and lower punch movement trajectory. On track by the upward thrust upward rail, on a downward track, washed up on the parallel tracks, press down tracks down on parallel tracks, such as more than orbit. They tighten on on track plate respectively. Orbit from down under and filling up rails, down down rail tracks. Seat respectively installed in orbit. 3 pack conditioning: filling adjustment for adjustment tablet weight. Filling device adjusting mechanism in the interior of the main body, in the main body of the plane can be observed that the filling of rail, it is the role of spiral and rising or falling to control the filling quantity, rotating disk adjustment, clockwise filling quantity decreased, vice versa. 4 piece of thick ( Pressure) Conditioning: by adjusting the press wheel up and down, to adjust the slice thickness ( Pressure) 。 Press wheel is installed in the main body of the tank, it set on the eccentric shaft, the outer side, to attach to a handwheel when outside the handwheel adjustment, eccentric shaft drive roller up and down, that is, adjust the slice thickness ( Pressure) , so as to control the thickness and hardness of the tablets, pressure on the wheel and also can be used as adjusting device, but do not move in the general case. 5 feeding device; The device consists of feed hopper, feeder, etc, the adjustable screw parts. Feeder for the grid type feeder, which is installed on the turntable. The height of the hopper and feeder and turntable working space adjusted according to the mobility of particles. 6 transmission device: the machine's transmission part is composed of motor, synchronous belt wheel and worm gear reducer, commissioning the handwheel, etc. Motor installed on the negatives of motor frame, motor starts, through a pair of synchronous belt transfer power to slow down on the worm gear pair. Motor speed is by ac frequency conversion stepless speed regulation to adjust. Open on both sides or the back door, can be directly observed and contact with these parts. 7 casing parts: the machine shell is fully enclosed, in line with the GMP requirements. Upper part there are four Windows and door, easy cleaning and maintenance. The lower part is stainless steel door closed, in the general case is lock closed, only when maintenance and installation of punching die to open the door. The front of the machine to install a work station. Tablet chamber separated by a stainless steel cover around and machine transmission part, ensure the tablet room clean and protect the transmission parts from powder pollution and corrosion.
