[0014] Please also refer to Figures 1 to 2 , a variable speed cutter device for absorbent articles, including a rotary cutter assembly 101 , a variable speed assembly 102 and a drive motor 103 .
[0015] Wherein, the rotary cutter assembly 101 includes a lower anvil roll 1 and an upper knife roll 2 .
[0016] The transmission assembly 102 is composed of three non-circular gear pairs 3 . Any pair of non-circular gear pairs 3 in the transmission assembly 102 is detachably connected to the anvil roller 1 and the knife roller 2 through a coupling and a pivot. The speed change assembly 102 is installed in the gear box 4, and the non-circular gears in the upper row in the speed change assembly are connected with the drive motor 103 through a coupling. The position of the speed change assembly 102 relative to the rotary cutter assembly 101 is movable.
[0017] The first angular velocity of the anvil roller 1 in the material cutting zone A near the cutter roller 2 is less than or ...
