Description

Technical Field

[0001] The utility model belongs to the technical field of packaging equipment, and particularly relates to a bag cutting machine. Background Art

[0002] The packaging bags filled with granule agents are detected as unqualified after weighing, and the granule agents need to be recycled. The Chinese patent with the publication number of CN116809439B relates to an automatic waste rejection and recycling device for bagged granule agents, including a small bag pushing channel. A weighing device is arranged at the end of the small bag pushing channel. A small bag discharging channel is arranged at the discharging port of the weighing device. A waste rejection device is arranged between the weighing device and the small bag discharging device. The waste rejection device is connected with a bag breaking and recycling device. The bag breaking and recycling device includes a waste material tank, the waste material tank is connected with a waste material fixing device, the waste material tank is connected with a bag breaking mechanism, the waste material tank is connected to a screening device. When it is detected that the number of waste materials in the waste material tank reaches a preset value, the waste material fixing device acts to fix the small bag, the bag breaking mechanism acts to break the waste bag, and the small bag after bag breaking enters the screening device for screening to obtain recycled granule agents. This structure cannot ensure that each bag is broken during bag breaking, and there is a risk that the bag breaking mechanism touches the granule agents, resulting in the granule agents being chopped and polluted.
