The components such as structure, transmission mechanism, pressure adjusting handle form；At work, through over packing, tabletting and slice step, currently, pinch roller
Pressure be arranged by setting value, but in tabletting, actual pressure is often inconsistent with setting value, this leads to following ask occur
Topic：One, the piece weight of tablet is overproof, i.e., tablet weight variation is more than the limit of States Pharmacopoeia specifications；Two, loose pieces, i.e., after tablet is pressed into, hardness is not
Enough, there is air marks on surface, i.e. fragmentation of gently being pressurizeed with finger；Three, sliver, i.e. tablet be given a shock or through place when, have from loins
Or top the phenomenon that splitting.At this stage, it can only offline be adjusted by pressure adjusting handle, the reality of degree of regulation and adjusting
When property cannot all be met the requirements.
Utility model content
The purpose of this utility model is to provide automatic rotary tablet press machine pressure-regulating device, which can be to pinch roller
Pressure carry out real-time control, avoid the tablet existing piece overproof, loose pieces of weight and the problems such as sliver in process of production.
Technical solution adopted by the utility model to solve its technical problems is：
Automatic rotary tablet press machine pressure-regulating device, tabletting machine controller is to tablet press machine drive control, the pressure tune
Regulating device includes stepper motor and one group of bearing pin sensor, the pressure adjusting handle axis connection of stepper motor and tablet press machine, axis pin
Sensor is detected the pressure of upper pressure wheel and lower pressure wheel, and bearing pin sensor output end is sequentially connected signal amplifying and conditioning circuit
With A/D conversion modules, A/D conversion modules output end is connected with tabletting machine controller input terminal, tablet press machine controller output end with
Stepper motor is connected.
Further, the bearing pin sensor uses four strain rosette foil gauges, four strain rosette foil gauges composition favour this
Energization bridge.
Further, tabletting machine controller periphery be also associated with display screen, printing interface, 485 communication interfaces with
EPROM。
The utility model has the beneficial effects that the pressure of upper pressure wheel and lower pressure wheel is detected by bearing pin sensor,
Actual pressure value feeds back to tabletting machine controller, and tabletting machine controller is according to actual pressure and the difference for setting pressure, to step
Stepper motor is controlled, to be automatically adjusted with dynamic pressure adjusting handle；The mode for having given up traditional manual adjusting, to pinch roller
Pressure carries out real-time online adjusting, avoids the tablet existing piece overproof, loose pieces of weight and the problems such as sliver in process of production.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples：
