AUTOMATIC BAG EMPTYING SYSTEM

A Fully Automatic Sack Emptying Station is designed for dust-free, high-capacity unloading of powder and granular materials from 25–50 kg sacks without manual intervention. It ensures consistent throughput, worker safety, and compliance with hygiene standards, making it ideal for pharmaceutical, chemical, food, and plastic processing industries.

In Automatic Bag Emptying system operates the roller conveyor line, the entire stack will be automatically conveyed into the catching position of bag slitter, the catching device of the bag slitter will come down to grab the whole layer bags layer by layer, and raise up to the set position, then move inside the machine, during this

process the cutter blade will cut open the bags from the bottom, material emptying device to empty the material inside the bag, the material by gravity fall into the hopper, empty bag into the waste bag compactor, which collect, compact and extrude out the waste bag.

When the whole stack bag is unpacked, the roller conveyor line will automatically transport the empty pallet to the pallet collector to complete automatic collection and stacking of the empty pallet.

No	Part Name	Description
1	Stack conveyor	Convey the stacked bags into the machine of bag slitter
2	Layer bag slitter	Cut open bag, separate the material and the bag
3	Pallet Palletizer	Collect and pile up de pallets
4	Empty bag compactor	Automatic collection, compaction of the empty bags
5	Hopper	Material outlet

Working Process:-

Sack Loading – Bags are placed on an infeed conveyor manually or via a pallet loader.
Automatic Bag Cutting – Rotary or guillotine blades cut open the sack in a controlled enclosed chamber.
Material Discharge – Contents fall into the receiving hopper, equipped with vibration or screw feeding for continuous downstream conveying.
Empty Bag Separation – Automatic removal of empty sacks via a discharge conveyor into a compactor or waste bin.
Dust Control – Integrated dust extraction ports ensure clean and safe operation.
Continuous Feeding – Material is directly fed into the process line via pneumatic, screw, or belt conveying.
