The weighing filling machine calculates the pulse signal of the pipe flow through the weighing module to obtain the actual liquid weight discharged by the weighing system, and controls the motor operation according to the difference between the actual filling amount and the set value, so as to achieve accurate control of the filling amount according to the actual needs. Automatic filling machine is mainly composed of DC frequency conversion motor, centrifugal pump, weighing instrument including touch screen control box, filling machinery, cylinder filling gun, filter, pneumatic ball valve and so on.
020-34563445The automatic Filling machine controls each weighing sensor, relay, switch and solenoid valve through PLC program. After the filling barrel is placed on the conveyor belt, it is transferred to the filling position by the conveyor, and the proximity switch arranged in the filling position automatically senses, and sends the sensing signal to the PLC control system, which controls the conveying motor to stop rotating, and controls the lifting cylinder to drive the roller arm up, and moves the filling barrel to the filling gun position. The photoelectric sensor at the port of the filling gun automatically senses the position of the filling barrel, and the cap suction device starts to suck the cap away; 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 metering module. 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.
When filling the Liquid filling machine starts, the switch starts the fast feed valve and the slow feed valve at the same time. When the weighing instrument measures the liquid mass in the barrel to reach the preset value of the slow feed amount, the fast feed valve will be closed, and the remaining mass will be filled by the slow feed valve. When the set quantitative value is reached, the slow feed valve will be closed. The system uses slow feed valve and fast feed valve to add raw materials in order to achieve high speed and accuracy. Carry out input weighing and sub-packing, as well as record, to realize the packaging management of material feeding. Weigh the input material manually or provide material information, and record the input material information. Receive the work order through information filling, convert the work order information into the execution parameters of the automation equipment, drive the equipment according to the work order instructions, and realize the batch control of the filling process.
