A support frame 8 is installed at the center of the shaft base plate 5, and a shielding piece 9 is installed on the support frame 8. Both ends of the shielding piece 9 are provided with a translation groove 10. An extension plate 11 is installed on the moving block 7, and a rotating shaft 14 is rotatably installed on the extension plate 11. The top of the rotating shaft 14 passes through the translation groove 10 and is equipped with a fixed bag support piece 16. A second pneumatic cylinder 12 is horizontally installed on the extension plate 11, and a short rack 13 is installed at the telescopic end of the second pneumatic cylinder 12. The rotating shaft 1 4 is mounted with a spur gear 15, and the spur gear 15 is meshed with the short rack 13, and a shank bearing 17 is mounted on the extension plate 11, and the shank bearing 17 is in contact with the outer wall of the short rack 13. The short rack 13 is driven to move by the second pneumatic cylinder 12, and cooperates with the meshed spur gear 15 to realize the rotation of the rotating shaft 14, thereby driving the fixed bag-supporting piece 16 and the lifting bag-supporting piece 18 to rotate. Before the bag is supported, the fixed bag-supporting piece 16 and the lifting bag-supporting piece 18 are rotated and stored above the shielding piece 9. When the bag is supported, the fixed bag-supporting piece 16 and the lifting bag-supporting piece 18 are rotated into the packaging bag, and the fixed bag-supporting piece 16 is moved upwards. A lifting bag-supporting piece 18 is slidably installed, and a third pneumatic cylinder 19 and an induction switch 20 are installed on the side wall of the fixed bag-supporting piece 16.

At this time, air is inflated into the packaging bag, and then the fixed bag-supporting piece 16 and the lifting bag-supporting piece 18 rotate until they are inserted into the packaging bag. At this time, the third pneumatic cylinder 19 moves up to drive the lifting ribs 21 and the lifting bag-supporting piece 18 to move up, and cooperate with the fixed bag-supporting piece 16 to open the packaging bag, making it convenient for the folded clothes to be placed in the packaging bag to complete the packaging. The moving distance of the lifting bag-supporting piece 18 is sensed by the induction switch 20.
