Nozzle assembly for a filling apparatus

摘要

A nozzle assembly (44) for a filling machine, the nozzle assembly controlling foaming and dripping of the product during and after the filling operation. The nozzle assembly includes a nozzle body (46), a fixed filling tube (48), a movable tube assembly (50), and movable cam structure (52). The movable tube assembly is provided with a sealing foot (80) through which a bore extends, the body being interconnectable with a vacuum line (66) after the completion of the filling of a container (16) to prevent dripping on the container. The movement of the movable tube assembly (50) is controlled by gear structure (100) associated with a valve (38) which controls the discharge of material through the nozzle assembly, in such a manner that the nozzle assembly will be closed when the valve is closed.
