[0002] Fabrics are commonly used materials in decorative materials. They include various fabrics such as chemical fiber carpets, non-woven wall coverings, linen fabrics, nylon fabrics, colored adhesive tapes, and flannel. Fabrics play a quite important role in decorative displays and are often the main force that cannot be ignored in the entire sales space. Composite filaments are often used in fabric materials.

[0003] Patent No. CN219972779U discloses a cutting device for producing composite filaments for fabrics. This cutting device for producing composite filaments for fabrics is provided with two sets of pulling components vertically below the clamping pair of rollers, which can quickly clamp and pull down the naturally drooping fabric, straighten the wrinkled part and then cut it, and can quickly reset after cutting. On the basis of a fast cutting speed, the cutting quality is improved. However, the fabric unwinding and clamping steps of this cutting device are controlled and operated by different motors, and there is a time difference in the startup of the motors, which will cause the fabric to be over-pulled and damaged, increasing the breakage rate and cost of the composite filament cutting link.

The cut fabric falls smoothly on the surface of the conveying frame 1 along the guiding plate 6.

[0033] All the electrical equipment in this solution is powered by an external power supply.

[0034] Working principle: When in use, the output shaft of the first motor 302 in the fixed box 301 rotates to drive the unwinding roller 304 at one end of the main roller 303 to rotate, and at the same time drives the driven roller 307 on one side of the inner wall of the belt 306 to rotate. The rotation of the driven roller 307 drives the right roller 308 and the main gear 309 to rotate. The rotation of the main gear 309 drives the left roller 312 at one end of the runner 311 on the side of the driven gear 310 to rotate, so that the cloth on the surface of the unwinding roller 304 passes through the surface of the transition roller 305 and droops to the left side of the rubber plate 410 under the drive of the rotation of the left roller 312 and the right roller 308. The electric push rod 407 on the side of the connecting frame 406 extends to drive the moving plate 408 to move. The moving plate 408 moves to make the rubber plate 410 on the side of the clamping plate 409 fit with the surface of the cloth, and makes the other side of the cloth fit with the clamping plate 409 on one side of the fixed plate 401 to clamp the cloth. The output shaft of the second motor 403 at the top of the fixed frame 402 rotates to drive the screw rod 404 to rotate. The rotation of the screw rod 404 drives the moving pipe 405 to move downward. The downward movement of the moving pipe 405 drives the moving plate 408 to move downward. The downward movement of the moving plate 408 drives the rubber plate 410 on the side of the clamping plate 409 to move downward. The downward movement of the rubber plate 410 drives the cloth that fits with the clamping plate 409 on the side of the fixed plate 401 to slide downward until the surface of the cloth is flat. The electric telescopic rod 504 on the side of the connecting plate 503 extends to drive the blade 505 to move leftward.
