Filling machines for big bags are adjusted so that they can be used to fill big bags of different types - the telescopic nosepiece allows the filling of big bags of a various height. In addition to the scale, the machines also feature equipment for air extraction during the filling process. Furthermore, it is possible to use a blower to blow up the inner lining before filling, the vibration base for an appropriate filling ratio, the roll conveyor for automatic removal of filled big bags, etc.
The operator places an empty big bag onto supports and connects the neck to the filling nozzle when the filling nozzle is in the lower position. The filling process is started by pressing a button, and the filling nozzle is lifted to the upper position. Dosing is automatic, and when the right weight is achieved, the big bag is lowered to the lower position. When the filling process is completed, the big bag is released, and it can be removed from the filling machine.
