The swing frame 95 may be configured into a rod shape with multiple folding angles, such that the upper portion thereof is connected to the second sliding frame 93 from two sides, the lower portion thereof extends to the middle position and can extend into the bag opening feeding mechanism 8 through rotation, and the push plate 92 at the lower end can push the diaper along with the movement of the second sliding frame 93 on the third rail 91; when one swing frame 95 swings downwards to push, the other swing frame 95 swings upwards to retract, and the two groups do not influence each other; the lower part of one second sliding frame 93 is swung upwards and then staggered relative to the upper part of the other second sliding frame 93, the structure is simple, the manufacture is convenient, and the parallel movement of the double-track upper structure is well realized without mutual interference. The swing frame 95 hinged on the second sliding frame 93 is controlled to swing by the material pushing cylinder 94, the moving characteristics of the material pushing cylinder 94 limit the upper and lower moving positions of the swing frame 95, the reliability is high, the structure is simpler, and the cost is reduced. The first servo motor 97 is used for synchronously driving the transmission belts 96 on the two sides, so that the arrangement of the motors and the transmission structure is reduced, and the cost of parts is reduced; specifically, the second sliding frames 93 on the two sides are respectively arranged on the annular lower section and the annular upper section of the transmission belt 96 shown in fig. 10, so that the opposite movement directions of the two sides are skillfully realized during synchronous movement, the complexity of a control system is simplified through synchronous movement, the second sliding frames 93 on the two sides can also be made to stably act, and the normalized operation and the matched conveying are facilitated.

The L-shaped side plates 81 and the lower plate 82 support and position the paper diapers well, and a plurality of paper diapers cannot fall from a gap between the lower plates 82 under the clamping and positioning of the side plates 81 on the two sides; the second screw 85 can drive the two nuts 87 with opposite rotation directions to move in opposite directions or in reverse directions when rotating, so that the distance between the two lower plates 82 on the sliding block 84 can be adjusted, the effect of adjusting the distance between the side plates 81 can be achieved, the bag opening feeding mechanism 8 can be freely adjusted to convey paper diapers with different specifications and quantities, and the packaging requirements of the paper diapers with different specifications can be met. The sliding block 84 is driven by a second servo motor 86 to slide back and forth on the sliding rail 83 and can move to different positions for positioning, so that the diaper can be bagged when arriving at the packaging bag conveying mechanism a and pushed into the packaging shaping mechanism 5 when arriving at the sealing and cutting packaging mechanism, smooth realization of an automatic processing line is facilitated, and good positioning and matching among multiple stations can be realized. The part that curb plate 81 stretches out outside hypoplastron 82 forms insert portion 88, and its distal end reduces gradually, forms the tip structure that more is convenient for stretch into the wrapping bag smoothly, has guaranteed a good cooperation of a bag feeding mechanism 8 with the wrapping bag, is opened better the wrapping bag by insert portion 88 under the condition of the preliminary bag of a bag of wrapping bag conveying mechanism department, realizes better a bag effect, guarantees that panty-shape diapers do not have the hindrance and get into the wrapping bag smoothly, improves the success rate of panty-shape diapers bagging-off.

The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above-mentioned embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and adaptations to those skilled in the art without departing from the principles of the present invention should also be considered as within the scope of the present invention.
