Automatic Quantitative filling machine according to the stepper motor at a pre-set speed through the screw drive filling valve rise: when the filling requirements are reached filling off, filling valve reaches the upper limit position travel switch stops and sends a signal. This data is compared with the host's rapid collection, real-time processing and the settings of the corresponding components in the recipe. If these two are the same, the host sends a control signal to stop the filling.

Liquid Automatic filling machine using computers to achieve the human visual function, the machine instead of the human eye to do the measurement and judgment, the use of photoelectric imaging system to collect the image of the controlled target, by the computer or special image processing module for digital processing, according to the image of the pixel distribution, brightness and color information, such as size, shape, color and other identification. This organically combines the rapidity and repeatability of the computer with the high degree of intelligence and abstraction of the human eye's vision, which greatly improves the flexibility and automation of the production process inspection, saves a lot of manpower, improves inspection efficiency and ensures product quality.

Weighing Quantitative filling machine can adjust the size of the filling volume by changing the rotational speed of the frequency converter gear, through the filling valve to the filling container dispensing liquid, control the switch on and off of the solenoid valve, drive the implementation of the lever drive to make the conical spool in the filling valve open or close, realize the liquid circuit intermittent opening and closing, showing the whole filling control process. Also can be achieved by controlling the number of running steps of the stepper motor to accurately control the number of revolutions of the gear pump so as to achieve the purpose of accurate measurement.

Liquid filling machine is a highly automated packaging equipment, its main function is to liquid materials into a predetermined set of weight. In the filling process can effectively avoid the material overflow, to prevent the maximum extent of the material itself on the environmental pollution, so as to effectively protect the operator labor. The system is stable and reliable, easy to operate and accurate in filling. It mainly consists of filling gun device, PLC system control part, weighing system, filling rack table, conveying equipment and so on.
