Since the surface of the wind-up roll 32 is provided with an adhesive layer, the non-woven fabric is easily adhered to the surface of the wind-up roll 32.

The wind-up roller 32 is arranged in the first clamping groove 4111 of the wind-up swing arm 411, the wind-up swing arm 411 abuts the wind-up roller 32 with the rotating roller 31 through the non-woven fabric, when the power supply of the wind-up driving piece 33 is turned on, the wind-up driving piece 33 drives the rotating roller 31 to rotate, the wind-up roller 32 abutting the rotating roller 31 is driven to rotate, and accordingly the wind-up roller 32 starts to wind up the non-woven fabric. In the winding process, the swing arm driving piece 415 drives the linkage gear 414 to rotate, and the winding swing arm 411 swings slightly in the direction away from the rotating roller 31 through the transmission of the crank gear 413 and the connecting rod 412, so that enough space exists between the rotating roller 31 and the winding roller 32 for winding.

When the winding is completed, the roll changing driving member 424 drives the driving sprocket 425 to rotate, the rotating ring 422 drives the roll changing arm 423 to start rotating through the transmission of the chain 427 and the driven sprocket 426, and when the roll changing arm 423 rotates to the roll placing groove 16, the extending arm 4232 guides the new winding roll 32 placed in the roll placing groove 16 into the second clamping groove 4231. Then, the rotary ring 422 continues to rotate, and when the roll changing arm 423 and the wind-up roll 32 rotate to a position right above the rotary roll 31, the cutting knife 432 extends out of the pneumatic slide rail 431, and the cutting knife 432 slides along the pneumatic slide rail 431 to cut the non-woven fabric.

After the non-woven fabric is cut off, the swing arm driving piece 415 drives the winding swing arm 411 to push the winding roller 32 which completes winding away from the rotating roller 31, meanwhile, the new winding roller 32 is in contact with the rotating roller 31, and the cut non-woven fabric is wound on the new winding roller 32 for pre-winding. After waiting for the winding swing arm 411 to swing and rotate the position of the movable roller 31, the rotating ring 422 continues to drive the roller changing arm 423 to rotate, and the new winding roller 32 is placed into the first clamping groove 4111 of the winding swing arm 411, so that winding is continued.

Because the extension arm 4232 is hinged to the roll changing arm 423, when a new wind-up roll 32 is placed in the first clamping groove 4111 of the wind-up swing arm 411, the extension arm 4232 rotates around the hinge point towards the outer side of the roll changing arm 423, and the new wind-up roll 32 is separated from the second clamping groove 4231 and does not interfere.

The present embodiment is merely illustrative of the present application and not limiting, and one skilled in the art, after having read the present specification, may make modifications to the embodiment without creative contribution as required, but is protected by patent law within the scope of the claims of the present application.
