Container filling machine with metered liq. vol. - has pistons of dispensers fixed to cross-member, motor driven via rotary feed screw

摘要

The liq. filling machine has a number of dispensing units, each with a cylindrical housing (38), in which a piston alternately draws in the liq. and discharges the metered vol. The pistons in the housings are parallel and rigidly secured to a cross member (8), to which rods (6,7) are, in turn, rigidly fixed, sliding parallel to the piston axes. The rods are coupled to a parallel, rotary feed screw (15) and belt- or chain-driven (19-21) from an electric motor (22), determining the speed of movement and length of stroke. ADVANTAGE - Controlled liq. delivery according to viscosity, to foaming etc.
