Description

Technical Field

[0001] This invention belongs to the field of textile application technology, and relates to Siro spinning, and more particularly to a dehairing device for Siro spinning. Background Technology

[0002] Compared to yarns spun using conventional ring spinning methods, Sirospun yarns offer advantages such as higher strength, less hairiness, and more uniform yarn evenness. In particular, processing the same thickness of ply yarn using other methods requires three steps: spinning the single yarn, plying and doubling, and twisting. Sirospun yarns, however, require only one step, thus offering the advantages of high efficiency and a shorter processing time. Based on these advantages, Sirospun yarns are increasingly widely used in the yarn industry.

[0003] Sirospun yarn is produced by feeding two rovings spaced at a certain distance onto a spinning frame. After drafting, these two single yarns are output as a single strand by the front roller. Due to the twisting effect transmitted from the point where the two yarns are about to converge, they acquire twist. At the convergence point, the two twisted single yarns are further twisted by the traveler in the twisting component, causing them to twist together and form a yarn with a ply-like structure, which is then wound onto a bobbin. A key characteristic of Sirospun yarn is its low hairiness. This is because during the twisting process, the fibers (hairs) that originally extended beyond the yarn shaft are encased within the ply due to the intertwining of the two yarns. However, hairiness remains in areas where the yarns do not touch. Therefore, although Sirospun yarn offers a significant improvement in hairiness reduction compared to conventional yarns, with a 30% reduction in hairiness after winding, it still falls short of actual requirements.

[0004] To further reduce hairiness, a dehairing roller is installed in the nip area formed by the front roller and the front roller, which rotates freely around the central axis. Two guide grooves are provided on the outer circumference of the dehairing roller. Two single strands of yarn fall into the two guide grooves respectively. The guide grooves gather and collect the fibers that extend beyond the surface of the single strands of yarn, so that the fibers outside the surface of the single strands of yarn are rotated and wrapped around the surface of the single strands of yarn as the single strands of yarn twist and rotate. When they reach the convergence point, the two single strands of yarn twist and coil together, and the fibers that have been wrapped around the surface of the single strands of yarn are wrapped inside the yarn, thereby reducing the hairiness of the yarn surface.

[0005] While the above structure can further reduce the amount of feathers, it still needs to be reduced further to meet actual needs. Summary of the Invention

[0006] This invention addresses the technical problems existing in dehairing of Sirospun yarn by proposing a dehairing device for Sirospun yarn that is simple in structure, easy to operate, and can further reduce the amount of hair.

Detailed Implementation

[0027] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0029] Example 1, as Figures 1-9As shown, this embodiment aims to provide a dehairing device for Siro spinning that can better bind hair to the spinning yarn, in order to solve the technical problem that existing dehairing devices need further improvement. To this end, the dehairing device for Siro spinning provided in this embodiment includes a dehairing roller 3 disposed in the nip area formed by the front skin roller 1 and the front roller 2. The conventional dehairing roller 3 is also disposed here, so it will not be described in detail in this embodiment.

[0030] The key improvement in this embodiment is that, in the traditional case, the de-hairing roller 3 is vertically rotating, while in this embodiment, the de-hairing roller 3 is horizontally positioned. The de-hairing roller 3 includes a roller body 31 and a rotating shaft 32 disposed within the roller body 31. The rotating shaft 32 is rotatably disposed within the roller body 31, meaning that the rotating shaft 32 rotates as the roller body 31 is in operation. A bearing is provided between the rotating shaft 32 and the roller body 31 to ensure the rotation of the rotating shaft 32.

[0031] Considering the self-twisting force of the yarn, two spiral guide grooves 311 are provided on the surface of the roller body 31, which are spaced vertically. Since the two yarns are spaced vertically, in this embodiment, the spiral angle of the guide grooves 311 is 180°. In this way, the yarn that enters from the top of the roller body 31 will exit from the bottom. Due to this spiral arrangement and the change in vertical position, the yarn will inevitably be set tightly against the roller body 31, and the change in spiral angle will help to restrain the hairiness.

[0032] Considering that the yarn itself has a certain twisting force, how to apply a rotational force to its outer side to further wrap the yarn hairs around the yarn, thereby achieving the purpose of binding the yarn. Therefore, in order to further bind the hairs and achieve the purpose of removing the hairs, in this embodiment, a hair binding mechanism is inserted into the guide groove 311. Specifically, the hair binding mechanism includes a binding seat 4 and a binding tube 5 rotatably disposed in the binding seat 4. In this embodiment, the binding seat 4 is a flat cuboid with a through hole in its middle and a groove at its bottom for placing the binding tube 5. In this embodiment, the binding seat 4 consists of two parts, front and back, which are fixed together by bolts to place the binding tube 5.

[0033] To facilitate the insertion of the restraint seat 4, in this embodiment, an insertion hole 312 is provided on the guide groove 311, and locking beads 313 are provided on the side walls on both sides of the insertion hole 312. A spring is provided between the locking beads 313 and the roller body 31. At the same time, a locking hole 41 is provided on the restraint seat 4. In this way, after the restraint seat 4 is inserted into the insertion hole 312, the locking beads 313 are squeezed into the locking hole 41 under the action of the spring, thus completing the fixation of the restraint seat 4. In this embodiment, the locking hole 41 is provided on both sides of the groove of the restraint seat 4.

[0034] In order to make the binding tube 5 rotate, in this embodiment, a rotating gear 51 is fitted on the binding tube 5. The rotating gear 51 is a helical gear and extends out from the middle slot of the binding seat 4. At the same time, a drive gear that meshes with the rotating gear 51 is provided on the rotating shaft 32. The drive gear is also a helical gear. In addition, bearings are provided on the front and rear sides of the rotating gear 51. The binding seat 4 also serves as a bearing seat. In this way, the binding tube 5 completes the rotation under the drive of the drive gear.

[0035] Considering that the overall size of the restraint seat 4 should not be too large, in order to minimize the size, in this embodiment, a ball groove is provided on the wall of the restraint tube 5 to replace the inner ring of the traditional bearing. In this way, the restraint tube 5 is the inner ring of the bearing. Only the balls need to be placed in the ball groove, and the outer ring 52 of the bearing is fitted on the outside of the balls to realize the rotation of the restraint tube 5. In this way, the setting of the inner ring of the bearing is eliminated, and the purpose of reducing the size is achieved.

[0036] Of course, the rotation direction of the binding tube 5 is the same as the rotation direction of the spinning thread and its rotation speed is greater than the rotation of the spinning thread. In order to further improve the binding ability of the binding tube 5 to bind the hair, in this embodiment, the binding tube 5 includes an inner tube 54 and an outer tube 53 fitted outside the inner tube 54. Connecting rings are provided at both ends of the inner tube 54, and threaded holes are provided on the connecting tube. The inner tube 54 and the outer tube 53 are connected by threads.

[0037] Due to the support of the connecting ring, a gap exists between the outer wall of the inner tube 54 and the inner wall of the outer tube 53, thus forming a placement cavity between the inner tube 54 and the outer tube 53. A roller 55 is installed within this placement cavity. In this embodiment, the roller 55 is arranged in a hollow shape, meaning that although the cross-section of the roller 55 is circular, it is thinner in the middle and thicker at both ends. A rotating shaft is fitted inside the roller 55. A roller hole 541 for placing the roller 55 is provided on the inner tube 54. The roller 55 extends into the inner tube 54 through the roller hole 541. Connecting plates 542 are provided at both ends of the roller hole 541. The connecting plates 542 have rotating holes, and a slot is cut at the top of the connecting plate 542 to connect with the rotating hole, thus inserting the rotating shaft into the rotating hole. Simultaneously, the roller 55 can rotate within the placement cavity under the action of external force. The rotation angle of the roller 55 is set perpendicular to the spinning direction.

[0038] To ensure better contact between the rollers 55 and the yarn, the rollers 55 are evenly distributed in a ring within the placement cavity. In this embodiment, four rollers 55 are provided, with a sealing protrusion 543 between adjacent rollers 55. The sealing protrusion 543 is located on the inner wall of the inner tube 54 to ensure the sealing between the rollers 55. In this way, after the yarn enters the inner tube 54, it will contact the rollers 55. At the same time, the twisting force of the yarn itself and the force of the yarn movement will drive the rollers 55 to rotate, and the binding tube 5 itself is also rotating. In this way, the hairiness can be further bound to the yarn. According to the test, the hairiness reduction can be achieved by more than 50%.

[0039] To avoid problems such as thread jamming, in this embodiment, the wall of the inner tube 54 is flush with the guide groove 311. The center of the inner tube 54 and the center of the guide groove 311 coincide, thus avoiding the problem of thread breakage caused by height differences.

[0040] To achieve the best binding effect, the hair binding mechanism is positioned where the spiral of the guide groove 311 changes. That is, the hair binding mechanism is located near both ends of the roller body 31, dividing the guide groove 311 into four equal parts, with two hair binding mechanisms positioned at each of the four quarters. This arrangement utilizes the spiral change of the guide groove 311 to further achieve the binding purpose.

[0041] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
