The weighing Filling machine uses weight method to measure, and controls the opening of the feed valve through the output signal of the weighing sensor to realize the purpose of automatic filling. The material is sent from the tank to the filling machine by means of feeding pump or pressurizing the raw material storage tank at the front end of the feed port. The filling amount can be freely adjusted within the applicable range, and the performance is more stable and reliable, and the filling amount is accurate. The filling machine adopts the optimized valve nozzle and valve core structure design, which can effectively avoid the spatter phenomenon when closing the valve after filling, and pollute the appearance of the product. After filling, the oil tray is extended to the bottom of the valve nozzle, which can effectively avoid the oil drop on the bottle after filling. In addition, like other equipment, all safety protective doors of weighing type filling are equipped with protection switches that meet the specifications. Once the protective doors are opened during the operation of the equipment, the equipment automatically stops to prevent accidental operation from causing injury to the operator. All the electrical components used are of high quality in accordance with European standards, and the electrical system is well grounded.

The Liquid filling machine controls the feeding according to the weight of the product collected in real time, and then packages or caps after filling. The Weighing system is a combination of high-precision weighing module, filling device and weighing instrument to realize fast and accurate filling. It can provide different production site solutions, support two kinds of discharge modes, and support the automatic lifting function of the discharge tube motor. Filling and weighing instrument provides complete control functions, integrated touch display, production management, sensor acquisition and processing, product detection in place, alarm output and other functions, can meet the user's production control requirements, high integration. The weighing module is responsible for collecting the weight signal, and outputs it to the PLC through the weighing instrument to complete the monitoring and setting of the filling operation page on the man-machine interface, setting the speed range of the inverter, the running state (filling/cleaning), the host switch, the filling speed and the output count. The operation of the main motor is controlled by the power button, the shutdown button and the man-machine interface setting button. The weighing sensor provides the filling weight signal for the controller, which corresponds to the filling valve to open the filling valve quickly and open the slow solenoid valve. The PLC determines the opening and closing state of the filling valve according to the operating position of the rotary encoder, and the bus transmits to the controller to open and close the filling valve, and the controller to set parameters, select the formula and recover the residue through RS485. After the filling is finished, a material recovery button is set on the filling weighing screen. There are residual materials around the filling valve body for recovery. After selecting the button, the recovery tank cylinder moves, and the residual materials enter the recovery barrel through the pipeline.
