Description

Technical Field

[0001] This utility model relates to the field of filling head technology, and more specifically, to an anti-drip filling head. Background Technology

[0002] Filling equipment is mainly used in the filling of wine and beverages. Based on the filling principle, it can be roughly divided into several types such as negative pressure filling machine, normal pressure filling machine, isobaric filling machine, quantitative filling machine, and material level filling machine. The filling head is an important component of the filling mechanism of the filling equipment. Existing filling heads are prone to dripping during production intervals and lack suitable anti-drip protection mechanisms. In addition, the anti-drip protection mechanism is directly exposed to the external environment by the drive motor during use, lacking suitable protection. Furthermore, the sealing end of the device is prone to wear after long-term use, which reduces its service life and makes replacement inconvenient. Utility Model Content
