[0024] Furthermore, the telescopic end of the hydraulic rod 301 extends through the middle of the second C-shaped support frame 3 to the lower end and is fixedly connected to the middle of the upper end surface of the fixed plate 4. The hydraulic rod 301 pushes the fixed plate 4 to rise and fall inside the second C-shaped support frame 3.

[0025] Furthermore, the upper ends of the four L-shaped connecting rods 401 extend to the inner side of the second C-shaped support frame 3 and are fixedly connected to the front and rear ends of both sides of the fixed plate 4, respectively. The four L-shaped connecting rods 401 are driven to rise and fall at the same time through the fixed plate 4, so that the two anti-slip pressing rollers 5 on both sides are raised and lowered, and the two sides of the non-woven fabric to be cut are pressed when the anti-slip pressing rollers 5 descend.

[0026] Furthermore, a transmission groove 402 is provided at the lower end of the L-shaped connecting rods 401 at the front ends of both sides, and a worm 403 is rotatably connected to the upper end of the transmission groove 402 .

[0027] Furthermore, a rotating shaft 501 is fixedly connected to the middle of the anti-skid pressing roller 5. The front and rear ends of the rotating shaft 501 are respectively inserted into two L-shaped connecting rods 401 for rotational connection. The front end of the rotating shaft 501 extends into the transmission groove 402 and is fixedly connected to a worm gear 502.

[0028] Furthermore, the worm wheel 502 on the rotating shaft 501 is meshed with the teeth of the worm 403, and the worm wheel 502 is driven to rotate by the worm 403, so that the rotating shaft 501 drives the anti-skid pressing roller 5 to rotate, so that the two anti-skid pressing rollers 5 simultaneously pull the non-woven fabric to move outward, so that the non-woven fabric between the two anti-skid pressing rollers 5 is tightened. After tightening, the self-locking principle of the worm wheel 502 and the worm 403 is used to prevent the anti-skid pressing roller 5 from rotating under the action of external force, so that the cutting machine 203 can perform cutting. After cutting is completed, the two anti-skid pressing rollers 5 rotate to one side at the same time, so that the non-woven fabric after cutting is transported to one side, and the other non-woven fabric moves to the lower end of the cutting machine into the cutting position, so as to achieve continuous cutting of the non-woven fabric.

[0029] Furthermore, a servo motor 601 is fixedly installed inside the motor box 6, and the front end of the worm 403 extends into the motor box 6 through the L-shaped connecting rod 401 and is connected to the output shaft of the servo motor 601 through a coupling, and the servo motor 601 drives the worm 403 to rotate.

[0030] Working principle: When in use, the non-woven fabric to be cut is placed on the cutting table 1, and the hydraulic rod 301 pushes the fixed plate 4 to descend inside the second C-shaped support frame 3. The fixed plate 4 simultaneously drives the four L-shaped connecting rods 401 to rise and fall, so that the two anti-skid pressing rollers 5 on both sides descend. When the anti-skid pressing rollers 5 descend, the two sides of the non-woven fabric to be cut are pressed, and the servo motor 601 drives the worm 403 to rotate, and the worm 403 drives the worm wheel 502 to rotate, so that the rotating shaft 501 drives the anti-skid pressing roller 5 to rotate. The two anti-skid pressing rollers 5 simultaneously pull the non-woven fabric outward, so that the non-woven fabric between the two anti-skid pressing rollers 5 is tightened. After tightening, the self-locking principle of the worm gear 502 and the worm 403 prevents the anti-skid pressing roller 5 from rotating under the action of external force, which is convenient for the cutting machine 203 to cut. After the cutting is completed, the two anti-skid pressing rollers 5 simultaneously rotate to one side, so that the non-woven fabric after cutting is transported to one side, and the other non-woven fabric moves to the lower end of the cutting machine into the cutting position, so as to realize continuous cutting of the non-woven fabric.
