After the box body and the frame plate 10 are flush with each other, the pneumatic cylinders 73 on both sides of the squeezing mechanism 7 are used to first drive the short side heads 72 to contact the air bag outside the box body for squeezing, and then the electric slide rails 75 on the other two sides drive the long side plates 71 on the vertical rods 74 to move along the slide grooves 76 to squeeze the other parts outside the box body, and the air bag is pressed tightly and pressed into the box body through the short side heads 72 and the long side plates 71 in turn. After the external air bag is pushed into the interior of the cargo box 6, the driving cylinder 41 drives the connecting rod 42 downward, the upper jig 3 at the end of the connecting rod 42 moves downward, the driving mechanism 4 drives the upper jig 3 downward to completely press the exposed air bag into the box body, and the squeezing mechanism 7 and the upper jig 3 are reset; a pad is placed on the box cover, and the upper pressure head cylinder 51 first drives the upper pressure plate 53 to move downward along the guide rod 52 until the opening 56 in the upper pressure plate 53 is outside the cargo box 6, and the surrounding distributed pushing is used. The cylinder 54 drives the buckle 55 to clamp the outside of the cargo box 6 to prevent it from moving, and then drives the connecting rod 42 downward by driving the cylinder 41. The upper fixture 3 at the end of the connecting rod 42 moves downward to press the box cover and the box body under the pad to prevent the decorative cover from having indentations. After pressing, the cargo box 6 on the fixed frame 82 is pulled upward by the lifting cylinder 81, and the clamping mechanism 9 releases the clamping of the cargo box 6, completing the folding of the air bag into the box body. The box body is small in shape and the entire air bag is folded to a size suitable for the box body.
