Automatic Filling machine adopts computer automatic control Electronic scale weighing operation selection of imported sensors, weighing stable vacuum pumping system to ensure no leakage, fast and slow filling, automatic jack function, filling head height can be adjusted by hand, suitable for different height of the packaging barrel, with automatic identification of empty barrel function and empty scale does not fill function. It is composed of feeding pump, solenoid valve, pipeline and Weighing system. When the liquid level of the reaction tank is lower than a certain position, the solenoid valve is opened, and the liquid flows through the feeding pump and pipeline into the batching tank. When the liquid reaches the liquid level height, the solenoid valve is closed. After the batching of the reactor, the liquid will circulate continuously from the lower side of the storage tank through the pump and pipeline to the upper part of the batching tank (clockwise). When the float level control in the reactor detects that the liquid level is lower than a certain position. The solenoid valve receives the signal. The bottom valve is opened, and part of the original clockwise circulating liquid flows to the filling barrel, so that the liquid level in the kettle is supplemented. When the liquid level reaches a certain set weight, the float level control sends a signal, so that the solenoid valve is powered off and the valve body is closed.

Automatic filling scales supply material to weighing drums in two sizes of flow. The weighing module converts the weight signal into an electrical signal and passes it to the weighing controller. The weighing controller measures the weight value, the program controls the whole weighing process, and configs the switch input signals including the start key, the shutdown key, the pit door status and other detection signals. Switch output is the control signal (such as thickness inlet solenoid valve, exhaust solenoid valve, pinch bag, etc.), weighing display, alarm output signal. The digital channel receives the weight input signal of the weighing module. The close test of weighing barrel door and clamp back is a close switch, and the buffer door, weighing barrel door and clamp back cover are driven and controlled by a solenoid valve. In the ideal state, the large supply is a small supply, together to complete 95% of the rated weight value, completed in a very short time. Then the large supply stops, and the small supply reproduces 5% 10% of the rated weight value for a longer period of time. In actual production, the weight and time parameters of these two segments must be constantly adjusted according to the situation in order to achieve the best state.
