The automatic bag-opening machine is an integrated automated system that combines bagged-material conveying, electric bag-cutting, screening and conveying, enclosed dust collection, and waste-bag collection. It is primarily used for opening bagged materials—typically in 20–50 kg sizes—and can handle a wide range of bulk materials, including powders, granules, and small chunks; it is even capable of processing paste-like materials with high gas content and high moisture levels.
Fully automated pallet storage and intelligent conveying equipment provides an automated pallet-loading solution for ton-bag packaging, enabling layered pallet storage, automatic pallet separation, and precise delivery to the packaging station—all without any manual intervention. The system is equipped with features such as pallet limiters, low-material alarms, and misalignment detection.
The vertical screw degassing packaging machine features a vertical screw with variable-frequency feeding combined with a negative-pressure degassing system. During the screw-driven material conveyance, a negative-pressure micro-porous tube extracts air from the material, while a bottom-mounted vibration platform and pneumatic cylinder-assisted bag-flipping mechanism further enhance mechanical degassing. This dual-stage degassing process delivers high efficiency, increasing the bulk density of the packaged material by 30%–50%. The equipment is primarily designed for gravimetric weighing and metering, and comes standard with air-bag bag clamping, automatic hook release, a standalone dust collector, and a negative-pressure degassing system. A lithium-battery-specific version incorporates copper- and zinc-free materials, anti-adhesion treatment, and corrosion-resistant coatings, making it suitable for ultra-high-air-content powders such as lithium-ion battery cathode and anode materials and carbon powder. After packaging, the ton bags maintain a neat, uniform shape with no bulging.
A dedicated integrated vacuum extraction and heat-sealing device for ton-bag openings, which performs internal vacuum degassing and oxygen removal while simultaneously heat-sealing the bag opening. This effectively prevents moisture absorption, oxidation, and powder re-agglomeration, with a specialized design tailored to the highly hygroscopic and oxidizable characteristics of ultrafine lithium-ion battery powders and chemical powders.
