The measuring cylinders of the filling machine are respectively connected to the filling head, and through the reciprocating motion of the main cylinder, a certain amount of liquid is sucked in, and then injected into the container to be filled. During this process, it is necessary to switch a through valve in a timely manner to change the flow direction of the liquid when the main oil cylinder is reversing. Moreover, during the injection process, in order to accelerate the filling speed without causing liquid overflow, when filling to 90% of the full bottle, a throttle valve connected in series in the injection channel should be opened to significantly reduce the injection flow rate.

Due to the extremely high filling accuracy requirements of the system, in addition to using internationally renowned quality flow meters as measuring instruments in the scheme design, the most advanced products in the world are also used as the main controller for data acquisition and control terminals; Three high-speed counting modules (5 channels/module, 100kHz) have been configured, which have fast acquisition speed, simple and convenient hardware configuration. The main material of the entire line is 316, and the fluid seal adopts EPDM, meeting the requirements of strong corrosion resistance and food grade. High degree of automation and advanced control technology.
