[0023] Directions:

[0024] In this embodiment, during operation, after the composite woven bag that has completed the bagging process is transferred to the bagging device station, the clamping cylinder of the clamping mechanism starts to work, and the clamping cylinder piston rod extends, so that the clamping plate clamps the upper and lower sides of the woven bag, playing the role of fixing the inner and outer bags of the woven bag. At this time, the piston rods of the clamping telescopic cylinder A and the clamping telescopic cylinder B are in an extended state. At the same time, the piston rod of the inner bag opening mechanism is extended, so that the suction cup on the bag opening plate contacts the opening of the inner lining bag of the woven bag. After the clamping is in place, the piston rods of the clamping telescopic cylinder A and the clamping telescopic cylinder B retract so that the telescopic splint A and the telescopic splint B clamp the left and right sides of the woven bag and gather in the middle; at the same time, the suction cup on the bag opening plate absorbs the opening of the inner lining bag of the woven bag, and the piston rod of the opening telescopic cylinder retracts, so that the inner lining bag of the woven bag is in an open state.
