Wherein, spout 101 has been seted up to the opposite face symmetry of two supports 1, pressure strip 6 and two spouts 101 sliding connection, set up breach 602 on the pressure strip 6, peg graft in the breach 602 and have cylindrical rod 601, set up on the toggle plate 502 and supply cylindrical rod 601 slip male slide hole 5021, the surface of cylindrical rod 601 and slide hole 5021's left surface and right flank slip butt, toggle plate 502 promotes cylindrical rod 601 when drive plate 5 anticlockwise rotates, cylindrical rod 601 drives pressure strip 6 along spout 101 towards non-woven fabrics 23's direction slip until pressure strip 6 compresses tightly non-woven fabrics 23.

In this embodiment, the weight of the lower inclined plate 501 is greater than that of the upper toggle plate 502, when the nonwoven fabric 23 is separated from the space between the first driving roller 20 and the first driven roller 19, the pushing plate 2104 moves down along with the inserting plate 2103, at this time, the driving plate 5 rotates clockwise under the action of the lower inclined plate 501, and then the upper toggle plate 502 pulls the cylindrical rod 601 to drive the pressing plate 6 to move away from the nonwoven fabric 23, so that the nonwoven fabric 23 to be cut is not blocked by the pressing plate 6 and reenters the space between the first driving roller 20 and the first driven roller 19, and the next cutting of the nonwoven fabric 23 is performed.

In this embodiment, the support 1 is fixedly provided with the guide plate 7 between the first driving roller 20 and the second driving roller 9, the non-woven fabric 23 between the first driving roller 20 and the second driving roller 9 is slidably located at the top of the guide plate 7, the top of one end of the guide plate 7 is lower than the second driving roller 9, and the other end of the guide plate 7 is located between the first driving roller 20 and the first driven roller 19 so that the non-woven fabric 23 can more smoothly enter between the first driving roller 20 and the first driven roller 19.

In this embodiment, in the initial state, when the pressing plate 2104 is lower than the bottom of the lower inclined plate 501 to make the swing box 2102 in the unlocked state, the swing box 2102 is not in contact with the lower inclined plate 501 during rotation, so that the transmission plate 5 does not affect the rotation of the swing box 2102.
