After the ton bag is transported to the destination, it needs to be cut open and the materials dumped into the collection equipment.

[0003] The traditional unpacking process requires two workers to work in the cabin on a single operation line, with their arms extended to the bottom of the ton bag when unpacking. There is a risk of being squeezed or hit by the cargo during the operation. Due to the large amount of dust generated during the unpacking process, workers are also at risk of being burned by highly corrosive cargoes such as sulfur and soda ash.

[0004] For example, the bag breaking and cutting mechanism for a ton bag unpacking machine with publication number CN208790092U includes a silo, at least one blade, and a blade driving device corresponding to the blade and used to drive the blade to move back and forth, wherein the blade is located above the silo; the blade driving device is connected to the blade, so that the blade driving device drives the blade to move to cut the ton bag, thereby allowing the material in the ton bag to enter the silo. The utility model drives the blade to cut the ton bag through the blade driving device, which saves time and effort, avoids the safety hazards of manual cutting, and has a simple structure, convenient maintenance, and stable and reliable operation.
