[0002] Bag unpacking machines are widely used in industries such as chemical, pharmaceutical, food, and building materials that need to handle bagged powdered materials.

[0003] Among them, many application scenarios require the unpacking machine to reach the sterile level, that is, it can be rinsed clean inside the unpacking machine and achieve a sterilization effect by spraying hot water or high-temperature steam.

[0004] The conveying method of multiple conveyor rollers arranged side by side with large gaps between them makes it easy for material bags to get stuck between the rollers. Therefore, to ensure that the material bags can be caught, the material conveying mechanism in existing bag unpacking machines mostly uses chain conveyor belts, that is, connecting rods are densely arranged between two rollers to reduce the gaps. However, chain conveyor belts are relatively complex structures, with many blind spots, and are difficult to clean with sprays. Utility Model Content
