These fibers are combined with each other by friction, adhesion or bonding to form fabrics that do not require yarn interweaving. Non-woven fabrics are moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, and are rich in colors, low in price, and recyclable. As a modern industrial product, non-woven fabrics have become an indispensable part of today's society due to their unique production process and wide range of applications.

[0003] After the non-woven fabric is processed, in order to facilitate its subsequent sales, it needs to be cut into appropriate lengths, rolled up after cutting, and then sold and so on. The existing slitting equipment cuts non-woven fabrics of different lengths by moving the blade. At this time, the non-woven fabric is still being transmitted, and the cutting point is fixed, which can easily cause pulling of the non-woven fabric, resulting in uneven cuts and affecting the quality.

9. A slitting method for a nonwoven fabric slitting device, characterized in that: The specific steps include: First, when in use, the raw material roller (11) is sleeved on the outer side of the movable shaft (8), one side of the raw material roller (11) is tightly attached to the limit plate (7), and the raw material roller (11) is fixed by friction force, and then the electric push rod (9) is started, and the electric push rod (9) drives the U-shaped block (10) to move upward until the U-shaped block (10) supports the movable shaft (8), and then the third motor (6) is started, and the third motor (6) drives the movable shaft (8) to rotate, so that the raw material roller (11) rotates, so that the raw material roller (11) can be conveniently discharged from the non-woven fabric; Afterwards, when in use, the non-woven fabric is passed between the first auxiliary rollers (2) and then passed between the second auxiliary rollers (12), and the non-woven fabric is tensioned by the first auxiliary rollers (2) and the second auxiliary rollers (12). At the same time, the fourth motor (38) drives the first auxiliary rollers (2) and the second auxiliary rollers (12) to rotate, thereby assisting in transporting the non-woven fabric. Afterwards, the non-woven fabric is wound around the outside of the winding roller (36) and wound up by the winding roller (36); Then, when cutting is required, the first motor (18) is started, and the first motor (18) drives the first screw (16) to rotate, so that the first slider (17) moves along the inside of the first track (15), and drives the second track (19) to move, so that the moving speed of the second track (19) is the same as the output speed of the non-woven fabric, so that the second track (19) and the non-woven fabric are in a relatively static state, and then the second motor (20) is started, and the second motor (20) drives the second screw (22) to rotate, so that the second slider (24) moves along the inside of the second track (19), thereby driving the cutting knife (25) to move until the cutting knife (25) cooperates with the baffle (23) to cut the non-woven fabric. When cutting, the non-woven fabric and the cutting knife (25) are in a relatively static state, so as to prevent the problem of rough cut surface caused by the movement of the non-woven fabric, ensure the slitting quality, and the device is started at a fixed time. Under the condition that the conveying speed of the non-woven fabric is consistent, it can be determined that the cutting length of the non-woven fabric is consistent; Finally, after slitting and cutting, the cut nonwoven fabric falls to the outside of the winding roller (36) at the lower end under the action of gravity and is fixed by negative pressure. Then, the winding roller (36) at the lower end rotates to carry out the subsequent winding work. The winding roller (36) that has completed winding is rotated to the upper end and manually removed, and then a new winding roller (36) is replaced. In this way, the winding work is still in progress during manual operation, which ensures the continuity of work and improves the winding efficiency.
