[0051] The working process of this embodiment is as follows:

[0052] A plurality of packaging bags 10 can be stacked on the supporting plate 2 in advance and placed between the bag pushing rod 22 and the limiting rod 25. Then the chain on the chain and sprocket transmission mechanism 21 moves, the bag pushing rod 22 pushes the packaging bag 10 to the set position, the chain stops moving, the vertical cylinder 32 on the bag moving mechanism 300 is actuated, the piston rod extends downward to drive the movable bracket 31 and the plurality of vacuum suction cups 34 to move downward, the plurality of vacuum suction cups 34 suck a packaging bag 10, and then the vertical cylinder 32 is actuated again, the piston rod retracts, and the plurality of vacuum suction cups 34 lift a packaging bag 10. Then the horizontal cylinder 33 moves to drive the vertical cylinder 32 and the movable bracket 31 to move horizontally, and the multiple vacuum suction cups 34 drive the packaging bag 10 to shift. Then the vertical cylinder 32 moves, the piston rod extends downward, and the multiple vacuum suction cups 34 place the packaging bag 10 on the bag receiving platform 4a. The multiple vacuum suction cups 34 remove the vacuum degree, and the vertical cylinder 32 moves again, and the piston rod retracts to drive the multiple vacuum suction cups 34 to rise and separate from the packaging bag 10. In this cyclic action, the packaging bags 10 on the bag supply platform 200 are moved one by one to the bag receiving platform 4a of the bag pushing mechanism 400, as shown in FIG. Fig. 9 As shown;

[0053] Then, the driving component 42 drives the bag pushing member 41 to move along the first yielding through hole 41a to push the packaging bag 10 on the bag receiving platform 4a to shift, and push the side of the packaging bag 10 with the bag opening to the bag receiving plate 5c of the bag opening mechanism 500; then, the aligning motor 51a rotates, and the two pairs of aligning rods 52a approach each other to push the packaging bag 10 on the bag receiving plate 5c to shift so as to align the bag opening of the packaging bag 10; then, the cylinder 521b is opened to drive the two lower vacuum suction cups 523b with the suction nozzles facing upward to move upward, and the slider 512b is opened to drive the two upper vacuum suction cups 514b with the suction nozzles facing downward to move downward, and the two upper vacuum suction cups 514b and the two lower vacuum suction cups 523b cooperate to suck the two outer sides of the bag opening of the packaging bag 10, and then the bag opening of the packaging bag 10 is opened;

[0054] Next, the second driving cylinder 62 is actuated to drive the rotating seat 6 to rotate, and the two bag-supporting rods 64 rotate accordingly, and the two bag-supporting pieces 65 are inserted into the packaging bag 10. The third cylinder 67 is actuated to drive the two slide seats 63 to move toward each other, and the two bag-supporting rods 64 move away from each other, and the two bag-supporting pieces 65 open the bag mouth of the packaging bag 10. Then, the second driving cylinder 62 is actuated again, and the two bag-supporting pieces 65 drive the packaging bag 10 to rotate to a position convenient for the insertion of the filling pipe 700 of the packaging machine, so as to realize automatic bagging. Fig.10 When filling the packaging bag 10, the packaging machine filling pipe 700 moves down and inserts into the packaging bag 10, and then a bag pressing cylinder 800 on the packaging machine is activated, and the piston rod drives the pressing block 801 to press the packaging bag 10 against the filling pipe 700. Then the first driving cylinder 61 is activated, and the two bag supporting rods 64 continue to rotate upward, and the two bag supporting pieces 65 are separated from the packaging bag 10, preparing for the next packaging bag 10 to be loaded.

[0055] During the bagging process, if the opening component 5b cannot normally open the bag mouth of the packaging bag, or the two bag-opening pieces 65 cannot normally be inserted into the packaging bag 10 to open the bag mouth of the packaging bag, at this time, the control unit can make a judgment based on the vacuum degree of the upper vacuum suction cup 514b and the lower vacuum suction cup 523b and the stroke of the two bag-opening rods 64, and then the packaging bag 10 needs to be removed to avoid affecting the normal bagging operation. At this time, the bag clamping cylinder 43 is actuated and the piston rod is extended to drive the bag pushing member 41 to rotate so that the two bag clamping parts 412 respectively cooperate with the two bag clamping supporting parts 461 to clamp the packaging bag 10 on the bag receiving platform 4a; then the sliding block 421 moves backward, the bag pushing member 41 moves backward, the two bag clamping parts 412 and the two bag clamping supporting parts 461 clamp the packaging bag 10 and retreat, the bag clamping cylinder 43 is actuated again and the piston rod is retracted, the bag pushing member 41 rotates in the opposite direction, and the two bag clamping parts 412 release the packaging bag 10, and then the piston rod of the lifting cylinder 47 is extended upward to push the bag receiving platform 4a to rotate and tilt, the bag pushing member 41 no longer hinders the packaging bag 10, and the packaging bag 10 automatically slides out backward. Fig.11As shown, the bag ejection action is completed; then, the piston rod of the lifting cylinder 47 retracts, and the bag receiving platform 4a rotates back in the opposite direction to carry out the bagging operation of the next packaging bag 10.
