Multi Layer Bulk Bag Unloader System For Automated Bulk Material Feeding
The TOVOT Multi-layer Bag Unpacker is an advanced automatic bag emptying system designed to improve material feeding efficiency in modern manufacturing plants. It automatically feeds, opens, empties, and collects stacked bags, reducing manual handling while ensuring a continuous supply of raw materials.
The equipment is suitable for plastic pellets, chemical granules, powders, and other free-flowing bulk materials. With its modular design, the machine can be integrated into existing production lines or supplied as part of a complete automatic material handling system.
Manual bag unloading often limits production efficiency and increases labor costs. The TOVOT Multi-layer Bag Unpacker automates the entire unpacking process, allowing operators to focus on production instead of repetitive manual work.
Automatic layer-by-layer feeding keeps materials moving steadily, reducing production interruptions.
The machine replaces manual lifting, cutting, and emptying, creating a safer and more efficient workplace.
The bag shaking mechanism helps discharge more material from every bag, reducing waste.
The modular design makes it easy to add conveyors, storage silos, weighing systems, or mixers as production grows.
| Multi-layer Bag Unpacker | Manual Operation |
|---|---|
| Continuous automatic feeding | Manual loading and cutting |
| Stable production flow | Frequent production stops |
| Up to 600 bags/hour | Lower handling efficiency |
| Lower labor requirement | Higher labor intensity |
| Dust-controlled operation | More dust in the workshop |
| Easy to integrate with production lines | Limited automation |
Palletized bags are automatically transferred to the unpacking station.
The machine separates each layer and feeds bags one by one into the cutting area.
The cutting device opens the bag quickly while maintaining stable operation.
Materials fall into the receiving hopper, while the shaking unit helps remove remaining contents.
Empty bags are automatically conveyed to the collection area for centralized disposal.
The discharged material can be transported to downstream equipment through screw conveyors, pneumatic conveying systems, or other customized solutions.
From pallet feeding to empty bag collection, the entire unpacking process is completed automatically.
Compatible with conveying systems, mixers, weighing equipment, storage silos, and feeding systems.
Industrial-grade components ensure stable performance during continuous production.
Machine dimensions, hopper design, discharge direction, and optional functions can all be customized according to your factory layout.
