[0002] Patent No. CN216186465U, a prior art publication, discloses a woven bag opening mechanism for use during bag filling. The mechanism comprises a main frame, an opening mechanism disposed on the surface of the main frame, and a side-holding mechanism disposed on the side of the main frame. The main frame comprises a bottom plate, two fixed side plates fixedly mounted on the top of the bottom plate, and opening tubes fixedly mounted on opposite sides of two telescopic opening rods. After the woven bag is opened, the side-holding rod is activated to move the lower side plate downward, allowing the top edge of the woven bag to be buckled against the fixed side plate. Subsequently, the fixed telescopic rod is activated to cause the fastening plate to press the top edge of the woven bag tightly against the abutment plate, effectively preventing the bag opening from slipping during filling.

[0003] The device opens the opening of the woven bag through structures such as a suction cup, an air pump and an air suction pipe. Due to the rough surface of the woven bag, the suction of the woven bag by the suction cup is still unstable after the air is pumped out, which can easily cause the suction cup to fall off. In addition, the device is large in size and complicated to use, which is not conducive to use. Therefore, a woven bag opening mechanism used when filling the woven bag is needed to meet the use requirements. Utility Model Content
