The synchronous movement simplifies the complexity of the control system and can also make the sliding frames 93 on both sides move stably, which is convenient for standardized operation and coordinated transportation. .

The "L"-shaped side panels 81 and lower panels 82 support and position the diapers well. Under the clamping and positioning of the side panels 81 on both sides, several diapers will not fall from the gap between the lower panels 82; the second The setting of the screw rod 85 can simultaneously drive two nuts 87 of opposite directions to move towards each other or reversely when it rotates, thereby adjusting the distance between the two lower plates 82 on the slider 84 and achieving the effect of adjusting the distance between the side plates 81 , so that the bag feeding mechanism 8 can be freely adjusted to transport diapers of different specifications and quantities, so as to meet the packaging needs of diapers of different specifications. The slider 84 is driven by the second servo motor 86 to slide back and forth on the slide rail 83, and can move to different positions for positioning, so as to realize that it reaches the packaging bag conveying mechanism a for diaper bagging, and reaches the sealing and cutting packaging mechanism to pack the diapers. The bag is pushed into the packaging shaping mechanism 5, which is conducive to the smooth realization of the automatic processing line, and the multi-station can be well positioned and coordinated. The part of the side plate 81 protruding out of the lower plate 82 forms an insertion portion 88, and its distal end gradually shrinks to form an end structure that is more convenient to smoothly extend into the packaging bag, ensuring the good cooperation between the bag feeding mechanism 8 and the packaging bag. In the case of preliminary bag opening at the packaging bag conveying mechanism a, the insertion part 88 can better stretch the packaging bag to achieve a better bag opening effect, ensure that the diapers can enter the packaging bag smoothly without hindrance, and improve the success rate of diaper bagging .

The above are only preferred implementations of the present invention, and the protection scope of the present invention is not limited to the above-mentioned embodiments, and all technical solutions under the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those skilled in the art, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
