the filling machine might be classed as a positive-displacement filling machine instead of a volumetric filling machine. These machines are manufactured with single or multiple filling heads, and they can be used manual as well as automatic operations. Each machine is also equipped with an adjustable piston stroke to permit a single unit to fill variable amounts of product.During operation, product is drawn into the piston cylinder head. As the piston reverses its travel, liquid product is discharged from the cylinder to into the container. If it is mechanical then the piston is driven by an eccentric crank connected to the driven shaft of the motor or speed reducer. The crank or piston rod is slotted to allow the piston stroke to be adjusted as required.
