Shanghai ELE Mechanical and Electrical Equipment Co., Ltd. is one of the most reliable manufacturers and suppliers of ton bag unloading system in China. Welcome to buy cost-efficient ton bag unloading system for sale here from our factory. Quality products and reasonable price are available.
Introduction
The ton bag unloading machine (also known as Jumbo bag unloading station or large bag unloading machine) is a specialized equipment designed for the efficient, dust-free and safe unloading of powder/particle materials in flexible ton bags (PP woven bags) weighing 500 - 2000 kg. It is widely used in industries such as chemical, building materials, food, pharmaceuticals, and new energy.
Key Constructure
- Rack and load-bearing hanger: Carbon steel / stainless steel, capable of supporting totes and equipped with an electric hoist (0.5 – 2t) for lifting and movement.
- Bag sealing device: Pneumatic / mechanical clamping, sealing the bag opening to prevent dust leakage.
- Unpacking mechanism: - Unbagging type: Manual rope release or pneumatic rope cutting (bags can be recycled).
- Bag cutting type: Automatic blade cuts the bottom of the bag (bags cannot be recycled).
- Hopper and agitator: Conical hopper + vibrator / tapping device, preventing material bridging and agglomeration.
- Dust removal system: Bag / cyclone dust collector, negative pressure sealed, dust does not leak out.(for option)
- Conveying interface: Can be equipped with pipe chain, screw, or pneumatic conveying to the next process.
- Electrical control system: PLC + touch screen, supporting manual/automatic, remote monitoring, emergency stop or Manual button for option
Working Principle
Core logic: Lifting → Sealing → Unpacking → Gravity Discharge → Assisting Flow → Dust Removal → Transportation.
1. Loading positioning: The forklift transports the ton bags to the workstation, and the electric hoist hooks the straps, lifting them above the hopper and suspending them.
2. Sealing bag closure: The bag opening is pulled into the bag closure device, and the air pressure clamps seal it; manually release the binding rope (for cutting bag type, start the cutting knife).
3. Unpacking and discharging: - Unpacking type: Slowly release the bag closure, and the material falls due to gravity.
- Cutting bag type: The blade cuts the bottom of the bag, and the material quickly falls into the hopper.
4. Assisting flow and preventing blockage: The vibration device and the tapping device operate intermittently to break up bridging and agglomeration, ensuring smooth material flow.
5. Dust treatment: The entire process is under negative pressure sealing, and the dust is collected by the dust collector, and clean air is discharged.
6. Material transportation: The material in the hopper is transported by the conveyor to the storage bin or production line; empty bags are collected and processed.
Specification
- Processing capacity: 2 - 6 bags per hour (approximately 1 - 3 tons per hour).
- Power supply: 380V/50Hz, 2.2 - 7.5kW.
- Air source: ≥ 0.6MPa, 0.3 - 0.6m³/min.
