The monofilament twisted interval broken fuzzing device disclosed by the embodiment of the application can be used for manufacturing broken fuzzing ropes. The single-yarn twisting interval broken fuzzing device utilizes the yarn separating component to pre-arrange the single-yarn bundles in layers in advance, so that the tight arrangement and the uniform twist degree can be ensured during twisting, and the uniformity of broken yarns can be ensured; according to the twisting principle of rope twisting, fiber monofilaments of different materials and different combinations are twisted and rotated to form monofilament twisting threads by utilizing the spaced thread breakage assembly, and in the process of moving the monofilament twisting threads, partial fiber monofilaments on the monofilament twisting threads are cut off by using the cutters arranged at intervals, so that the technical effect of forming fiber wool by spacing thread breakage is realized, and the length and the number of the broken fiber monofilaments can be further controlled by matching and adjusting the length, the shape and the number of the cutters and matching the twisting twist and the thread feeding speed; the carding assembly is utilized to comb the broken fiber monofilaments, and during the movement of the monofilament twisted yarns, the broken fibers are carded in a single direction through carding, so that the broken yarns are prevented from being twisted into the monofilament twisted yarn body in the twisting process, and the broken yarn fuzzing effect is prevented from being influenced; all the components are mutually matched, so that the uniformity of single-wire twist and broken yarn fuzzing can be ensured, and broken yarns can be fully exposed. The single-wire twisting interval broken yarn fluffing device can greatly improve the broken yarn fluffing efficiency and quality, improve the twist stability of twisted yarns, ensure the appearance uniformity and the strength stability of broken yarn fluffing ropes, greatly reduce the generation of unqualified products and improve the production efficiency.
