In order to achieve the purpose of adjusting the measurement size and improving the measurement accuracy, the solution filling machine adopts the stepper motor to control the speed and revolution of the screw, fast and slow two or fast, or slow, slower three stage filling mode, the target amount is set freely, through the cooperation of PLC and TR700, the servo controller controls the stepper motor to accurately run to the specified revolution and accurate discharge. Interlocks are set in the program to ensure the orderly and reliable operation of the moving/discharging mechanism during filling.
020-34563445The weighing and Filling machine is composed of stepper motor, gear pump, filling head, conveyor belt and electrical control box. The electrical part mainly includes stepper motor drive power supply, positioning solenoid valve, counter, cylinder filling head, conveying motor and corresponding control circuit. The filling machine mechanism is connected with the driving shaft of the ruler wheel pump through the output shaft of the stepper motor installed by variable speed reduction. The stepper motor can be used as the power source of filling liquid, and the speed of the gear pump can be accurately controlled by controlling the number of steps of the stepper motor, so as to achieve the purpose of accurate measurement. The filling machine uses PLC signal to drive the motor and other transmission mechanisms to drive the manipulator to move, and at the same time drives the encoder with the motor to feedback the number of abusive pulses to the driver. The driver compares the two pulses and determines the deviation, and the correction signal obtained after a certain control law is used as the given speed controller in the servo driver and then is adjusted by current and amplified by power. Make the grasping manipulator move in the direction of eliminating the deviation, so as to realize the stacking positioning of the manipulator.
The automatic linear Liquid filling machine is through the front and back movement of the cylinder with the piston in the cylinder for reverse movement, so that the front chamber of the cylinder produces negative pressure, and the signal valve controls the stroke of the oxygen cylinder, which can adjust the filling amount, so as to achieve accurate filling effect. The filling machine includes piston cylinder, piston head, YX ring, check valve, filling head, feed pipe, discharge pipe, etc. When cleaning all seals, it should include the piston YX ring, the valve plane seal ring, and replace the broken and damaged seal ring. The filling production line has intelligent PLC program control system, high efficiency, each filling head has a separate component control, thus ensuring the high-speed filling accuracy of the automatic liquid filling production line.
