[0002] At present, in order to produce non-woven fabrics of different widths, a slitting machine is needed to slit the non-woven fabrics. Companies usually unwind and slit the non-woven fabric mother roll to be slit, and then rewind the slit non-woven fabric roll onto the winding core shaft. Finally, the slit non-woven fabric roll is pushed out and placed on a new winding core shaft, the non-woven fabric on the pushed out non-woven fabric roll is cut and the winding core shaft is pulled out.

[0003] However, in the actual production process, the existing slitting machine has the following defects:

[0004] 1. The surface tension control accuracy of non-woven fabrics is poor during transmission, which easily leads to problems of excessive or insufficient tension, which is not conducive to the slitting and winding of non-woven fabrics;

[0005] 2. Non-woven fabrics cannot maintain stable high-speed transmission. Each time a non-woven fabric roll is cut, the non-woven fabric wound on the reel needs to be manually separated from the non-woven fabric on the back side, and then the reel is pulled out of the machine, and finally a new reel is put in. The operation is cumbersome, time-consuming and labor-intensive, and it is difficult to meet the needs of high-efficiency production. Summary of the Invention
