Pull the film tape of the upper film roll 7 through the tensioning cylinder 17 to the rear roll rack 3 and bond it to the head of the lower film tape. Adjust the height of the inner column 18 to make the lower side of the tube ring sleeve 9 and the electric heating gate plate 15 fit tightly with the upper film tape. The upper film tape at the fitting position presses the overlapping lower film tape below tightly against the top surface of the belt 104. The driving motor 5 is started to roll the upper and lower film strips onto the rear roll rack 3. During this process, the diapers are placed one by one at the entrance end of the conveyor platform 1. When the diapers pass under the hot roller mechanism, the rotating roller 8 embosses a sealing ring around the diapers through the raised tube ring sleeve 9. The upper and lower film strips at the sealing ring are bonded together to seal the diapers in the ring. Then, the electric heating gate plate 15 that moves up and down embosses easy-tear lines at both ends of the combined film strip that seals the diapers. The sealed diapers are rolled onto the rear roll rack 3 together with the combined film strip.

[0021] The driving motor in the utility model can pull the lower film belt to transfer the diaper to the bottom of the hot rolling mechanism. After the tube ring sleeve 9 in the hot rolling mechanism rotates one circle with the roller 8, the diaper can be sealed between the upper and lower film belts that are combined into one. The combined film belt is pressed with easy-to-tear lines at both ends of the packaged diaper by the hot cutting mechanism, and finally the film belt is rolled up and collected on the rear roll rack 3, which has the characteristics of automaticity and high efficiency.
