This mechanism is very fast when sealing tubes hence saving time.
It consumes less power and seals nice looking and different shape of the tube.
4. Dosing Systems In Plastic Tube Filling Machine
Vacuum Filling Mechanism
The filling mechanism is simple and straight forward:
- Empty the vane cell.
- Move the vane cell under the hopper.
- Pour the material from the hopper slowly into the cell by a vacuum pump.
Piston Filler Mechanism
Pour material inside the cylinder. Use a piston to push the material from the cylinder into the tubes which are present below the piston nozzles.
Pour the right volume of the material inside the tubes using the filler. Travel to the capping station to cap the tubes.
Gravity Filling Mechanism
Program the filling time of the nozzles to help fill the tubes with an accurate volume of material. In the filler machines, gravity force makes material flow smoothly inside the tube.
Of course, there are machine using volumetric filling mechanism.
