Automatic Filling machine adopts high-precision weighing sensor to measure liquid weight, can use gravity flow mode or motor pump feed, filling process adopts two-speed filling method, fast filling to improve efficiency, slow control method adopts frequency converter or choke reflux control filling accuracy, with precision control valve to complete the automatic filling process, and add waste gas recovery cover. Receiving tray or suction and other technologies. Double speed filling method, fast filling in the front section to ensure efficiency, slow filling at the back end to improve control accuracy. The anti-interference ability of measuring and weighing is very strong, and the stability is very high. High precision weighing sensor, empty drum placed in the filling area, press the start button, will automatically peel, net weight weighing type measurement. Self-brought suction (receiving tray) placement of drip to avoid the surrounding working environment pollution caused by filling. The control system adopts PLC program control, with automatic manual switching function, automatic is used in normal operation, manual mode is used for debugging and maintenance and emergency treatment, operation and maintenance is simple. Weighing instrument is a high sensitivity digital display instrument, with weight display, automatic elimination of subtle interference, automatic correction of drop, out-of-error alarm and other functions.

The Liquid filling machine places the filling barrel on the conveyor belt and transmits it to the filling position by the conveying motor; At this time, the proximity switch arranged in the filling position automatically senses, and transmits the sensing signal to the PLC control system; PLC controls the conveying motor to stop rotating, and controls the lifting cylinder to drive the roller arm up and move the filling barrel to the position of the filling gun; At this time, the photoelectric sensor located at the port of the filling gun automatically senses the position of the filling barrel, and sends the signal to the PLC control system. When the filling barrel reaches the predetermined position, the PLC controls the synchronous motor to stop rotating, and the cap suction device starts to absorb the cap; Then the filling gun begins to fill the liquid into the filling barrel, and the weight signal of the liquid in the barrel is transmitted to the PLC control system by the weighing sensor; When the predetermined weight is reached, the PLC controls the filling gun to stop filling, the cap suction device automatically seals the cap, starts the conveying motor, and carries the filling barrel away.
