The bulk bag discharge station is a highly automated equipment designed to handle pre-prepared bags. It features automated processes such as robotic bag retrieval, bag opening, weighing and feeding, vacuum extraction, sealing, and discharge. Additional functions like inflation and inkjet marking can also be integrated into the workflow. Widely used in industries such as chemicals, fertilizers, pharmaceuticals, and construction, it is a mechanical device for unpacking and discharging bulk materials packaged in ton bags, including powders, granules, small lumps, and ultrafine powders. Recognized for its environmental benefits, energy efficiency, and durability, it has gained widespread acceptance across various sectors.

The discharge station primarily utilizes an electric hoist integrated into the unpacking machine to lift the material bag onto the frame of the unpacker. The bag is then lowered gradually. During this slow descent, the discharge outlet of the bag is manually opened or cut open using a cross-cutting knife. The material slides out under gravity, allowing the powdered or granular contents of the ton bag to fall into the storage hopper, completing the discharge process.

The bulk bag discharge station incorporates environmental protection features by employing a fully sealed design during the unpacking and discharge process. This effectively prevents dust pollution. It rapidly captures dust generated by the material and returns it to the discharge outlet through fixed pipe walls, ensuring environmental compliance without material loss.

Its *advanced design structure allows for the tapping of materials that form lumps or are difficult to discharge within the large bag, facilitating smooth transfer to the next process. It also removes foreign objects mixed in the material, maintaining purity and preventing potential issues in subsequent usage.

Manually placing raw material bags onto the conveyor belt initiates the process. The belt conveyor transports the bags into the unpacking machine, where a rotating bag-breaking device cuts them open. The raw material falls through the screening holes of a rolling sieve into the discharge hopper, while the empty bags are rotated out by a drum and discharged via a bag removal mechanism. Dust generated during cutting is treated by a built-in bag filter system in the automatic unpacking machine. The dust collected in the filter bags is returned to the unpacking machine through a pulse cleaning device, enabling dust reuse. The air purified by the bag filter can be safely discharged indoors. The unpacked raw material is then transferred via a discharge screw, which can be paired with equipment such as elevators, screw conveyors, tubular chain conveyors, or pneumatic conveying systems for further processes like batching, mixing, or packaging.
