Problems solved by technology

However, the biggest defect of the porcelain eye is that during the yarn guiding process, because of the friction between the yarn and the magnetic eye, it is easy to scrape the filament, such as carbon fiber, causing fiber damage; it is easy to cause flipping, and the yarn is easy to form false twist. When unwinding, the yarn reciprocates from one end of the bobbin to the other. As the yarn reciprocates, the yarn also slides from one side to the other in the yarn guide magnetic eye. For many reasons, in actual operation, false twist

Embodiment Construction

[0039] Such as Figure 1 to Figure 5 As shown, the present invention provides a yarn guiding device, comprising a fixed base 1, the fixed base 1 is provided with at least two rotating guide rollers 2, the axes of the guide rollers 2 are parallel to each other, and between the guide rollers 2 with gaps.

[0040] For the double-roller parallel design, when the yarn is used for bobbin unwinding, during the reciprocating movement of the yarn from one end to the other end, the yarn is always in contact with a rotating guide roller, because the yarn has a certain tension and will not cause The yarn is reversed and another guide roller determines the direction of the yarn exit. Because the guide rollers are all rotating, there is no relative sliding with the yarn, and the fibers will not be damaged.

[0041] In this embodiment, the fixing seat is provided with at least two rotating guide rollers, the axes of the guide rollers are parallel to each other, and there is a gap between t...

Abstract

The invention discloses a yarn guide device, which comprises a fixing seat, wherein the fixing seat is at least provided with two rotating guide rollers, the axial lines of the guide rollers are mutually parallel, a gap is formed between the guide rollers, each guide roller comprises a fixing shaft and a roller body bearing assembly, the fixing roller is arranged on the fixing seat, the roller body bearing assembly is rotatable, is arranged on the fixing shaft in a sleeving way, and comprises a hollow roller body, the two ends of the hollow roller body are respectively embedded with a bearing seat, the two bearing seats are respectively provided with bearings, the two bearings are respectively provided with a bearing support end cover, the center of each bearing support end cover is provided with a shaft hole, the inner end of each baring support end cover is provided with a tubular shaft liner coaxial with the shaft hole, the tubular shaft liner passes through the shaft hole of the bearing, and the roller body bearing assembly is arranged on the fixing shaft through the shaft hole of the bearing support end cover in a sleeving way. The yarn guide device has the advantages that during the yarn guiding, the fiber turning cannot be easily caused, yarns cannot easily form false twisting, and the yarn abrasion can be reduced.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a yarn guiding device. Background technique [0002] In the prior art, the yarn guide component used for guide wire, guide yarn or wire is a porcelain eye. The porcelain eye is exactly a small porcelain ring or a small porcelain cylinder with holes. The structure of porcelain eye is simple, the price is cheap, and the use is very common. However, the biggest defect of the porcelain eye is that during the yarn guiding process, because of the friction between the yarn and the magnetic eye, it is easy to scrape the filament, such as carbon fiber, causing fiber damage; it is easy to cause flipping, and the yarn is easy to form false twist. When unwinding, the yarn reciprocates from one end of the bobbin to the other. As the yarn reciprocates, the yarn also slides from one side to the other in the yarn guide magnetic eye. For many reasons, in actual operation, False twist...
