The present invention relates to material-filling equipment technical fields, disclose a kind of filling suction unit and filling suction method, filling suction unit includes that component is taken out in aggregate tank, compressed gas valve, vacuum valve, exhaust valve and multiple fillings, and aggregate tank includes interconnected air chamber and material cavity；Air chamber is connected to pressurized gas system by compressed gas valve, so that the pressure of air chamber is greater than atmospheric pressure；Air chamber is connected to vacuum system by vacuum valve, so that the pressure of air chamber is less than atmospheric pressure；Air chamber is connected to ambient atmosphere by exhaust valve, so that the pressure of air chamber is equal to atmospheric pressure；It fills and takes out component for connecting container to be filled or to be pumped.The filling suction unit integrates the filling of material and suction, realizes the accurate filling of material, greatly reduces the waste of material, filling and suction can also be carried out to multiple containers simultaneously, filling and suction efficiency is improved, while the device is easy to operate, it is easy to use. |
