In these applications, powder bag unpackers can quickly and accurately unload powdered materials, improving production efficiency and reducing labor costs while protecting operator safety and environmental cleanliness.

[0003] During the unpacking operation, the material belt is driven by the conveying device to pass through the cutting station, discharge station and bag discharge station in sequence. At the cutting station, the cutting mechanism cuts the material bag open; at the discharge station, the material falls into the hopper; finally, at the bag discharge station, the empty bag is sent to the bag discharge bin and discharged directly from the bag discharge bin.

[0004] At present, a commonly used conveying device is to lift the material bag filled with material and send it to the cutting station, where the cutting mechanism at the cutting process cuts the material bag open; then it is lifted to the upper side of the hopper, that is, the unloading station, so that the material falls into the hopper, and then the empty bag is lifted to the bag discharge station, the empty bag is released, and finally it returns to the initial position to lift the next bag of material, and so on.

[0005] Only after the previous bag of material is unpacked and the conveying device is reset can the next bag of material be lifted and unpacked. That is, one complete stroke of the conveying device can only complete one unpacking operation. Therefore, the unpacking efficiency is low. Utility Model Content
