Automatic Layer-by-Layer Bag Opening Machine for PP Pellets
The TOVOT Automatic Layer-by-Layer Bag Opening Machine is designed for automatic unloading of PP pellets and other plastic granules packed in stacked bags. It automatically separates each layer, opens the bags, empties the materials, and transfers empty bags for collection, providing a clean, stable, and efficient feeding solution for modern plastic processing plants.
With intelligent PLC control and a fully automated operation process, the machine minimizes manual handling, reduces material loss, improves production efficiency, and creates a safer working environment.
Solutions
Why Upgrade to an Automatic Layer-by-Layer Bag Opening Machine?
Improve feeding efficiency, reduce labor costs, and ensure clean, continuous material unloading for PP pellet production.
Comparison
Automatic Bag Opening VS Manual Bag Opening
Processing Capacity
- Up to 800-1,200 bags per hour (depending on bag size and material)
Labor Saving
- Manual unloading usually requires 4-6 workers per shift
- Automatic operation only needs 1 operator for machine monitoring and forklift loading
Cleaner Production
- Reduce dust during bag opening
- Minimize material residue inside bags
- Improve factory cleanliness and working conditions
Stable Material Supply
- Continuous feeding to the downstream conveying or storage system
- Reduce production interruptions caused by manual unloading
How It Works
The complete system includes an automatic layer separating unit, bag opening system, material discharge hopper, empty bag collection unit, and intelligent PLC control system.
The working process is as follows:
- Forklift places the stacked bags onto the feeding conveyor.
- The machine automatically separates one layer from the stack.
- Each bag is transferred to the bag opening station.
- The bag is cut automatically and PP pellets are discharged into the hopper.
- Empty bags are collected automatically.
- The pellets are transferred to the next process through the conveying system.
The entire process is fully automatic, reducing manual work while ensuring stable material feeding.
