then, the bag opening arm 514 is driven by the bag opening cylinder to extend into the space between the outer bag and the inner bag of the packaging bag to open the outer bag; because the tail end of the piston rod of the lifting cylinder 511 is connected with the bag opening mechanism 512, one end of the pulley rope 524 is connected with the weight 525, and the other end of the pulley rope 524 bypasses the pulley 522 and is connected to the bag opening mechanism 512, the lifting cylinder 511 extends downwards, the weight 525 moves upwards, and the bag opening arms 514 are controlled together to stably push the outer bag to move downwards, so that the inner bag is separated from the outer bag. The lifting cylinder 511 and the weight 525 act together to avoid the damage to the packaging bag caused by overlarge acting force when the lifting cylinder 511 is instantly started and stopped.

Subsequently, the bag twisting arm 5422 is closed, the inner bag of the packaging bag is clamped, the rotary motor 541 rotates to drive the bag twisting arm 5422 to control the inner bag to rotate, in the rotating process, the bag twisting arm 5422 resets, the inner bag is gradually wound and thinned, the bag bundling cylinder 531 downwards pushes the bag bundling machine 533 to a bag bundling station, the servo drive 532 controls the bag bundling machine 533, the bag bundling machine discharges a bag bundling wire, the opening of the inner bag is wound tightly, and the bag bundling wire is cut short; the band binding mechanism 53 moves upwards step by step, and resets after finishing multiple times of bag binding.

Then, the lifting mechanism 55 is reset, the lifting cylinder 511 and the weight 525 act together to drive the bag opening mechanism 512 to reset, the outer bag is lifted upwards to the original position, the inner bag opening is fastened, and the outer bag opening moves to the next procedure under the state of being opened.

The belt tying machine 533 is provided with a servo drive 532, the belt tying machine 533 comprises a shell 5331, a reel 5332 and a workbench 5333, the workbench 5333 is arranged above the shell 5331, one end of the workbench 5333 extends out of the shell 5331, the reel 5332 is arranged on the shell 5331 and at the other end of the workbench 5333, the extending end of the workbench 5333 is provided with a groove 5334, a tying wire on the reel 5332 bypasses the servo drive 532 and penetrates out of the groove 5334 downwards, the servo drive 532 controls the tying wire to be wound tightly, an inner bag opening is wound tightly, and the tying wire is cut off.

As shown in fig. 8, 9 and 10, the rancour bag mechanism 6 has the working principle: the last process is a ribbon binding process, the packaging bag with the inner bag mouth screwed up and tied is completed, the carrying trolley 7 conveys the packaging bag to a rancour bag station, two sets of bag opening arms 68 extend into the space between the inner bag mouth and the outer bag mouth of the packaging bag to open the outer bag mouth outwards; the bag opening cylinder 63 extends downwards again, the outer bag is pushed downwards through the telescopic arm 67 and the bag opening arm 68, and the bag twisting mechanism 614 is prevented from being influenced to bend the inner bag opening;

the bag twisting arm 616 relatively slides along the base plate 615 to clamp the inner bag opening of the tightening binding line, and the rotary motor 65 rotates to drive the bag twisting arm 616 to bend the inner bag opening;

rancour bag cylinder 64 pushes rancour bag arm 612 and rancour bag frame 613 to push the inner bag mouth into the outer bag mouth;

the bag opening cylinder 63 contracts upwards to lift the outer bag opening upwards, so that the inner bag opening is completely arranged in the outer bag opening, and the outer bag opening can be sewn conveniently in the next process.
