Description

Technical Field

[0001] The utility model belongs to the technical field of spinning equipment and relates to a transverse swinging yarn device, in particular to a transverse swinging yarn device which can reduce the loss of mechanical properties of fibers. Background Art

[0002] During the spinning and winding process, the traverse swinging device is a key component that rubs against the tow. Conventional traverse swinging devices make linear reciprocating motions in the vertical direction of the tow. If the friction between the tow and the traverse is too large, or the swing angle of the tow is too large, the mechanical properties of the tow will be greatly reduced, especially for rigid or semi-rigid materials such as aramid fiber, liquid crystal polyester fiber, poly(p-phenylene benzobisoxazole) fiber and new solvent-based regenerated cellulose fiber. Therefore, the design of the traverse swinging device seriously affects the tow forming and the mechanical properties of the tow.

[0003] Existing patents focus on improvements to the transverse swing wire device, including installation structure, service life, wire breakage, tension adjustment, wire amplitude, friction reduction, prevention of wire detachment, and synthetic fiber fineness.

[0004] For example, Chinese invention patent CN109230860A provides a new rabbit head device for a wire collecting machine for improving the width of carbon fiber tows. By innovatively modifying the rabbit head wire guide roller and increasing the width of the carbon fiber product tow, it eliminates factors such as passive twisting due to equipment reasons in the production process, but does not pay attention to damage to the mechanical properties of the tow.

[0005] Chinese utility model patent CN205634463U sets a first wire guide device and a second wire guide device structure, which can reduce the tensile force of the elastic fiber during the winding process, which is beneficial to improving the winding quality of the elastic fiber and ensuring the stability of the fiber, but does not pay attention to the impact on the mechanical properties of the yarn bundle.

[0006] Chinese utility model patent CN217263821 U provides a device for enhancing the yarn spreading of a large-tow carbon fiber winder, which effectively solves the problems of uneven spreading and shrinkage of large-tow carbon fiber winding, and has certain guiding significance for the production and winding of large-tow carbon fiber.

[0007] Chinese utility model patent CN210163578U discloses a traverse guide for a false twist texturing machine, including a tension adjustment plate, a transmission shaft at both ends of which is provided, a plurality of annular guide rings are provided on the transmission shaft, the surface of the guide ring is a threaded ring arranged along its axial direction, and a limit seat is provided on both sides of the guide ring, and the guide ring can extend into the inner side of the limit seat. The utility model discloses a traverse guide for a false twist texturing machine, wherein a plurality of threaded rings arranged along its axial direction are provided on the surface of the guide ring, so that the untwisted yarn can pass through the guide ring better, and by providing a magnetic ring 1 at both ends of the guide ring, and a magnetic ring 2 having the same magnetic properties as the magnet 1 is provided on the outer side of the limit seat, so that the oblique downward force generated by the untwisted yarn on the guide ring during the left and right deviation process will drive the guide ring to move slightly in the horizontal direction, reduce the mutual friction or extrusion with the guide ring, avoid the fluffy or deformation phenomenon of the spinning yarn, and improve the spinning quality.

[0008] Chinese utility model patent CN204939682U relates to a production system of thick denier spandex yarn, and in particular to a spandex thick denier yarn guiding system with a constant wire guiding distance; it mainly solves the technical problem that when the winding machine traverses the wire guide and clamps the thick denier yarn to move back and forth laterally, due to the large inertia of the wire, the thick denier yarn swings too much, which easily causes the wires of adjacent winding heads to be entangled and rub against each other, causing winding breakage, spider web yarn, etc. The utility model includes a second wire guide roller, a finger-shaped wire guide is provided below the second wire guide roller, the finger-shaped wire guide is connected to the winding machine beam through an adjusting slide rod, a traverse wire guide is provided inside the winding machine beam, a friction roller is provided at one end of the traverse wire guide, and a winding roller is provided on one side of the friction roller.

[0009] Chinese utility model patent CN203034163U relates to a novel polyimide fiber winding machine, including a frame and a lifting platform arranged in the frame, a tension wire guide roller, a friction roller and a winding roller are arranged in front of the frame, the friction roller is connected to the lifting platform, a driving mechanism of the friction roller is arranged on the lifting platform, the tension wire guide roller is arranged on the frame above the friction roller, the winding roller is arranged on the frame just below the friction forming roller, the friction roller is a friction forming roller, and a forming groove is arranged on the roller surface of the friction forming roller. The conventional winding machine's traverse wire guide is no longer used, and the friction roller is changed to a friction forming roller to realize the forming of the wire roll. The friction forming roller is a forming roller with a groove instead of the original smooth roller. The shape of the groove is the same as the forming of the wire roll. Since the rotation direction of the friction forming roller is the movement direction of the wire bundle, the friction forming roller drives the wire bundle to move horizontally while rotating. The friction between the wire bundle and the friction forming roller is very small, and no hairy wires and broken wires are generated, so that the wire roll is well formed and easy to unwind.

[0010] However, the above improvements still cannot overcome the problem that the strength and elongation at break of the fiber are greatly damaged. When using the traditional rabbit head guide wire, the friction between the fiber and the rabbit head is large, the tension along the fiber axis is unstable during the reciprocating wire collection process of the rabbit head, and the fiber has a small angle bend, so the strength and elongation at break of the fiber are greatly damaged.

[0011] In view of this, there is an urgent need to design a new traverse-motion swing wire device to overcome at least part of the above-mentioned defects of the existing traverse-motion swing wire device. Utility Model Content
