Liquid Filling machine to achieve the whole filling requirements, with high weighing accuracy, short weighing time, human-computer interaction interface friendly, high resolution. By setting parameters, zero points and calibrating weighing instruments, accurate weighing of the corresponding set weight can be accomplished. At the beginning of measurement, the switch starts the fast feed valve and the slow feed valve simultaneously open to inject liquid into the barrel. When the weight meter 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, and the slow feed valve will be closed when the set quantitative value is reached. The system uses slow feed valve and fast feed valve to add raw materials in order to achieve high speed and accuracy. The whole process can be set up and observed through the touch screen.

The frequency converter can control the spiral speed to adjust the filling weight, and measure the instantaneous flow through the electronic balance. The frequency converter can adjust the spiral speed, adjust the quantity equal to the set value, and complete the automatic filling process. Use weighing control to start the feed pump of the raw material until the qualified weight of the material is sent to the filling barrel, which will include all the control and interlock of the feed and discharge valves, the start and stop of each feed pump, the control of fast and slow feeding, the status detection, and all the data processing functions. It is composed of weighing unit, data processing unit and logic control unit, which work independently of each other and are closely connected by question and answer. Flexible and mobile, while improving the degree of automation, but also improve the reliability of filling, to ensure that users can long-term trouble-free operation.
