Structure & Composition

• Material inlet

• Feeding mechanism (pneumatic gate)

• Weighing hopper

• Bag clamping mechanism

• Frame and air suction port

• Pneumatic system

• High-precision sensor

• Control box

• Conveyor and sewing mechanism

Working Principle

1. Material Feeding: The feeding mechanism delivers material into the weighing hopper.

2. Intelligent Weighing: The controller receives real-time weight signals from the sensor and manages the feeding process in three stages—fast, medium, and slow—to ensure precise filling.

3. Bag Handling: Once the target weight is reached, the bag clamping mechanism secures the bag, and the discharge door opens automatically.

4. Sealing & Conveying: The filled bag is released onto the conveyor, transported to the sewing machine for sealing, and then moved to the next process.

5. Continuous Cycle: The system resets and prepares for the next bag, ensuring uninterrupted, efficient operation.
