The liquid Filling machine mainly consists of components including spray gun device, weighing device and controller, unpowered roller conveyor and gas collection hood. Using liquid level weighing filling method, it is suitable for the filling of liquid materials without foam or light foam. The specially designed spray gun is easy to operate and fast and accurate to fill. To ensure maximum leakage of residual liquid. The collecting hood can effectively protect the operator from harmful gases. In the process of operation, the operator simply aligns the barrel mouth directly below the spray gun nozzle, presses the "start" button, and the empty barrel will be automatically stripped, and then the precise two-speed filling will be carried out. After the filling is completed, the spray gun automatically lifts the barrel, takes out the full barrel, and completes the filling.

Automatic filling machine can realize data printing, microcomputer network management and storage, programmable weighing management, automatic production detection of controlled electrical equipment, weighing technology to achieve transparent factory concept, developed into dynamic weighing, process weighing, data storage/output, greatly improving work efficiency. The application of inverter control technology deals with the shape and quality of the product, adjusts the transportation speed and direction, and plays a role in the material conveying and handling system, including labeling machine and output conveyor. Automatic microcomputer technology will gradually play a role in the field of filling, improve the application level of mechatronics, automatic weighing and Filling system to weigh objects in motion, by the weighing module and filling other components of the dynamic Weighing system closed-loop automatic control system, according to the signal characteristics and values given by the weighing system, proportional to the mass of the DC component is separated.
