When the bag breaking work is performed, the material bag is manually placed on the conveyor belt. When the material belt is conveyed, the cutter cuts the bottom of the material bag, causing the material to fall from the cutter edge. However, in this bag breaking device, the falling of the material after the bag is broken only relies on gravity, the material falls slowly, and the falling efficiency is low. Moreover, after the cutter is fixed, the power for the relative movement between the cutter and the material bag is only provided by the conveyor belt. When the cutter becomes blunt or the outer skin of the material bag is tough, the cutter will find it difficult to cut the material bag, causing the material bag to accumulate on the conveyor belt, greatly affecting the bag breaking work.
