The automatic Filling machine adopts the S7-200 PLC control system, uses the weighing controller to supply power to the weighing module, collects small signals, amplifies and then outputs the standard 0-5V or 4-20mA output; PLC through the standard analog module to collect signals, and then through the transformation, calibration, through the PLC man-machine interface input the corresponding parameters, through the PLC integrated digital quantity control filling, dosing and other metering tasks; A large number of bulk liquid materials are automatically divided into small loads of predetermined weight for quantitative packaging. The liquid material transported by weight or power is automatically loaded into a number of standard empty barrels, and the material weight of each barrel is quantitatively controlled by opening and closing the valve.

Weighing and filling machine is composed of filling, capping, sealing, palletizing, weighing equipment and corresponding conveyor belt, supplemented by automatic control and automatic adjustment system. When the four-riser barrel arrives at the feed conveyor belt, the barrel is separated by a spiral barrel Feeder and sent to a fixed weighing platform under the injection nozzle of the rotating oil tank. The quantitative filling is to arrange the piston cylinder symmetrically around the circular rotating oil tank, and each piston is connected with a shaft by a connecting rod and slides according to the inclined circular trajectory. The first 180 degrees of inclined circular motion causes the piston to rise, and the last 180 degrees causes the piston to fall. Filling machine When the piston is lifted, the material is controlled by the valve from the upper oil tank into the piston cylinder. When the valve connecting the piston cylinder to the injection nozzle is opened, the material is injected into the lower barrel.
