The invention discloses an automatic
ton bag unpacking device. The automatic
ton bag unpacking device comprises a
ton bag with an outer layer and inner tongue double-layer structure, a supporting frame made of an aluminum
alloy material and used for mounting components, a rail arranged at the top of the supporting frame and a power device for driving the ton bag to transversely move and longitudinally move along the rail. The automatic ton bag unpacking device is characterized in that disassembling devices, a discharging
barrel arranged at the bottom end of the supporting frame, ascending anddescending in the longitudinal direction and connected with an inner tongue in a sleeved mode, an inner bag knife arranged in the discharging
barrel, and a
barrel hoop arranged at the outer end of thejoint of the inner tongue and the discharging barrel and used for sealing and fixing are further included; and the disassembling devices are connected with three-level hydraulic cylinders through transition pieces separately and are driven by a
control unit, the three-level hydraulic cylinders are all fixedly arranged on the supporting frame, the rail for lifting of the inner bag knife is arranged in the discharging barrel, and the inner bag knife drives a
rope to ascend and descend in the rail through a motor. By means of the automatic ton bag unpacking device, automatic bag unpacking operation is achieved, and accidental leakage of
powder in the bag unpacking process is avoided.
