[0002] With the development of mechanical automation, many production steps in traditional production processes are gradually replaced by automated machinery, which not only greatly improves production efficiency, but also saves a lot of labor costs. Filling machines are a small category of packaging machines. According to the type of packaging materials, they can be divided into liquid filling machines, paste filling machines, powder filling machines and granule filling machines. According to the degree of production automation, they can be divided into semi-automatic filling machines and fully automatic filling production lines.

[0003] During the filling process, liquid will remain at the liquid outlet of the filling machine. When the liquid outlet is pulled out from the bottle body, the residual liquid will drip onto the equipment, which will contaminate the equipment and require the staff to clean it from time to time, which is troublesome.
