Description

Gravity Ton Bag Packing Machine Overview

The Gravity Ton Bag Packing Machine uses Ton Bags (FIBC, Big Bag, Container Bag) as packaging containers and is widely applied for bulk storage and transportation of powder and granular materials.

Features of Gravity Ton Bag Packaging Machine

  1. Gravity self-feeding system: Material falls naturally by gravity, resulting in a simple and reliable equipment structure.
  2. Three-stage adjustable speed feeding: Flexible switching between fast, rough, and fine feeding stages.
  3. High sensitivity weighing system: Equipped with a high-quality load cell for real-time material weight feedback.
  4. High degree of automation: Automatically completes bag clamping, filling, measuring, bag loosening, and unloading.
  5. Easy operation: Only manual bag hanging and removal are required, saving labor.
  6. Durable structure: Designed to adapt to harsh environments such as ports, mining, and chemical industries.

Advantages of Gravity Type Tonnage Bag Packing Machine

  1. High efficiency: Rapid gravity discharge ensures high filling capacity per unit time.
  2. High precision: Three-stage feeding mode improves weighing accuracy; error can be controlled within ±0.2%.
  3. Low energy consumption: No extra power required for material flow, reducing operating costs.
  4. Strong applicability: Adaptable to most powdery or granular materials with good fluidity.
  5. Easy maintenance: Simple structure is easy to clean and maintain for a long equipment life.

Working Principle of Gravity Ton Bag Packaging Machine

Material descends by its own weight through the hopper into the ton bag. The three-stage valve controls the material flow speed: fast feeding at the start, medium-speed filling in the middle, and slow, fine filling at the end. The weighing system dynamically monitors the process; as the target weight nears, the feed slows to precisely reach the set point. After filling, the bag is automatically loosened for convenient forklift handling. The PLC control system integrates sensor signals for intelligent operation and error correction, ensuring stable packaging quality.
