Filling machine is a combination of weighing module, weighing instrument and filling system. The system can achieve the measurement work of weighing and distributing the filling barrel, so as to control it. Can directly access PLC system, terminal control system, to achieve multi-pass control and automatic control. The filling system digitizes the weak weight signal output by the weighing module to obtain the high-precision weighing data. The software is equipped with rich digital filtering technology, and the emergency software to prevent the interference system from getting out of control.
020-34563445Automatic Filling machine In order to ensure the accuracy and speed of the control system, the quantitative filling scale feeding device adopts straight down feeding, double screw feeding and other methods. After the quantification begins, the size Feeder works at the same time, stops the large feed when the weight of the material reaches the large feed set value, and continues to maintain the small feed, and closes the small feed when the weight of the material reaches the final set value. It adopts the three-level control method of frequency converter, and the gross weight without bucket is mainly composed of storage bin, rotor feeder, transition device, cutting device, weighing unit, cylinder device, pneumatic part, capping part, finished product conveying part and electrical control unit. The weighing part is mainly composed of weighing bucket, weighing module, weighing instrument, etc., which can complete the accurate measurement of materials and send the control signals required by the control system: over and under signal, preset lead signal, lead signal, target value signal, 4~20mA analog signal and standard RS232/485 signal.
The measuring instrument controls the programmable controller and inverter to set the equipment in the automatic working state, turn on the automatic button, and start the filling machine for primary feeding. When the preset lead is reached, the weighing unit sends out a signal and the inverter switches to the secondary feeding mode. When the lead is reached, the weighing unit sends out a signal and the inverter switches to the three-stage feeding mode. The hopper is closed, the gun is lifted, the cap is blocked, and the system automatically switches to the power frequency state for the next cycle. The size of the feeding amount of the filling machine is mainly determined by the speed of the rotor feeder, the speed of the rotor feeder is controlled by the frequency converter, and the size of its capacity is directly related to the selection of the frequency converter specifications. The control terminal is used to complete the operation control of the multi-stage speed, the frequency combination state corresponding to the three-stage feed, the parameter is set and modified through the man-machine interface, the fault self-diagnosis result is directly displayed on the man-machine interface, and the soft starting mode is adopted to avoid the mechanical impact on the motor and extend the service life of the motor. It is easy to achieve over-current, over-voltage and under-voltage protection through the parameters set by the inverter itself.
