The small gear can drive the screw rod 6 to rotate through the large gear. However, the setting of the small gear and the large gear makes them located in the middle of the gantry 2, which is not convenient for rotation. Therefore, the present application preferably adopts the small sprocket 3, chain 4 and large sprocket 5.

[0042] It should be noted that the specific type of edge banding motor 9 and electric heating block 13 to be used is a matter for the relevant technical personnel familiar with the field to choose, and the above-mentioned edge banding motor 9 and electric heating block 13 are all existing technologies and will not be elaborated in this solution.

When the sanitary napkin is an ultra-thin model, rotate the small sprocket 3, the small sprocket 3 can drive the chain 4 to rotate, and the chain 4 can drive the large sprocket 5. The radius of the small sprocket 3 is smaller than the radius of the large sprocket 5, which can produce a deceleration effect on the large sprocket 5. The large sprocket 5 can drive the screw rod 6 to rotate, and the screw rod 6 is arranged to rotate with the gantry 2 through the bearing to ensure that the screw rod 6 ensures the smooth rotation of the screw rod 6, the lifting bar 7 can drive the lifting bar 7 to move downward, the lifting bar 7 can drive the support frame 8 to move downward, the support frame 8 can drive the edge sealing motor 9, the rotating wheel 10 and the edge sealing ring 11 to move downward, until the distance between the edge sealing ring 11 and the crawler conveyor 1 meets the thickness requirement of the sanitary napkin, the electric heating block 13 is turned on, the electric heating block 13 can heat the edge sealing ring 11, the edge sealing motor 9 can drive the rotating wheel 10 to rotate, the rotating wheel 10 can drive the edge sealing ring 11 to rotate, and the edge sealing ring 11 can perform edge sealing on the sanitary napkin.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
