Big Bag Packaging Machine

The Big Bag Packaging Machine, also known as a bulk bag filling station or FIBC (Flexible Intermediate Bulk Container) packing machine, is designed for efficient and automated packaging of bulk materials into large bags, commonly referred to as “ton bags” or “jumbo bags.” These machines are widely used in industries such as mining, agriculture, chemical, building materials, and metallurgy for the packaging of granular and powdery materials.

Working Principle:

1. Variable Speed Feeding Mechanism:
   • Comprises an adjustable speed motor, belt drive, spiral shaft, and feeding mouth with a vacuum port.
   • Controlled by an electric box, the material is fed from the bin into the packing bag via the screw.
2. Weighing Frame:
   • Connected to weighing sensors that transmit the weight signal of the material to the electrical box.
   • The electric box controls the entire machine, including the start, stop, speed, and cylinder lifting of the charging motor.
3. Bag Placement and Clamping:
   • The packing bag is set on the discharging spout, and the four corners of the bag are hung on the cylinder hooks.
   • The pressure cylinder starts to work, pressing the bag mouth and opening the four corners of the bag.
4. Material Filling:
   • The controller automatically tares the weight of the bag.
   • Material is poured into the bag by spiral rotation, and the vibration table vibrates the material to settle it within the bag.
5. Dust Collection:
   • Dust generated during the filling process is sucked away by a vacuum cleaner connected to a dust collector.
6. Weighing and Adjustment:
   • When the feeding speed reaches the preset value, the screw speed slows down, and the vibration stops.
   • Once the set weight is reached, the feeding stops, the cylinder loosens the bag mouth, and the bag is ready to be transported.
7. Discharge and Transport:
   • The filled bag is released and can be moved by a forklift or conveyed to the next process.
