Reversely-rotating pre-filament-separation system device for mother filaments

Abstract

The invention belongs to the technical field of FDY mother filament tools and particularly relates to a reversely-rotating pre-filament-separation system device for mother filaments. The reversely-rotating pre-filament-separation system device for the mother filaments comprises an FDY mother filament frame, filament guiding hooks and monofilament cakes, a lower filament guiding rod and an upper filament guiding rod are arranged above the FDY mother filament frame, thereby the mother filaments can be naturally dispersed and arranged on a reversely-rotating godet wheel side by side, monofilaments are separated naturally when the mother filaments leave the reversely-rotating godet wheel, and filament separating points are fixed to points, from which the mother filaments leave, of the reversely-rotating godet wheel. The reversely-rotating pre-filament-separation system device has the advantages that the filament separating point positions are fixed, so that tension tightness is avoided; the filament separating point positions are raised, so that tension differences among all spindles are decreased; in the FDY mother filament separating process, tension is maintained stable, monofilament rupture is avoided, and the monofilaments are maintained being shaped up in a good condition.

Description

technical field [0001] The invention belongs to the technical field of FDY mother silk appliances, and in particular relates to a counter-rotating pre-separation system device for mother silk. Background technique [0002] During the splitting process of the FDY mother wire on the splitter, because the mother wire 1 is in the untwisted unwinding process, the tow passes through the lower guide rod 2, the upper guide rod 3, and then the speed measuring wheel 4 and the guide wire hook 5. Subdivided into the guide wire hook and spindle of each monofilament yarn cake, so as to complete the division of FDY mother wire into monofilaments. Due to the cohesive force of the FDY tow after oiling in the production process, the tow slides over the wire guide hook 4 and is forcibly separated between the guide wire hook and the spindle. Since the FDY mother wire is unwound by the mother wire The tension of the beam and the dynamic cooperation of the friction plate to rotate and unwind wil...

AI Technical Summary

Problems solved by technology

Due to the cohesive force of the FDY tow after oiling in the production process, the tow slides over the wire guide hook 4 and is forcibly separated between the guide wire hook and the spindle. Since the FDY mother wire is unwound by the mother wire The tension of the beam and the dynamic cooperation of the friction plate to rotate and unwind will easily cause FDY to fluctuate up and down at the dividing point between the guide hook 4 and the spindle, resulting in unstable monofilament tension. Because the monofilament fineness is very small, only between 15-30D , the absolute breaking strength is low, and the unstable tension is easy to cause a single wire breakage, and the mother wire splitting fails

[0003] For this kind of FDY mother wire splitting equipment, the disadvantages in the splitting system are: 1. Since the automatic splitting point of the mother wire is close to the wire guide hook of each spindle, the tension of the monofilament on each tube after the splitting The difference is uneven, the middle is small, and the two sides are large, which is easy to cause a single wire to break; 2. The mother wire splitting point is greatly affected by the tow and cannot be fixed. The winding forming is not good, and it will also cause the monofilament to break and stop the machine
