Description

Technical Field

[0001] This utility model relates to the field of yarn textile equipment technology, and in particular to a device for improving the surface smoothness of yarn. Background Technology

[0002] In the yarn manufacturing industry, surface smoothness is one of the key indicators for measuring yarn quality. It directly affects the core properties of subsequent textiles, such as appearance, feel, and dyeing uniformity. Whether it's combed cotton yarn used in high-end apparel fabrics or synthetic fiber yarn used in industrial textiles, the market's requirements for burr-free, impurity-free, and smooth-textured yarns are constantly increasing. Therefore, surface polishing during yarn production has become an indispensable core process for optimizing yarn quality.

[0003] Currently, the mainstream yarn polishing methods in the industry mainly rely on two types of core equipment: ceramic polishers and polishing polishers. Among them, ceramic polishers, with their high hardness and strong wear resistance, can effectively remove fuzz and initial impurities from the yarn surface. However, due to the design of a single polishing structure, their ability to repair fine protrusions and textures on the yarn surface is limited. While polishing polishers can further improve the smoothness of the yarn surface through flexible polishing materials, they are difficult to efficiently handle more obvious roughness and protrusions on the yarn surface.

[0004] In traditional production, due to the limitations of equipment functionality, most processes employ a "one-time polishing" approach, using only one type of polishing tool—either a ceramic polisher or a sanding polisher—to complete the polishing process. This single-process method has significant drawbacks: if only a ceramic polisher is used, while it can remove obvious impurities from the yarn surface, fine fuzz and rough textures will remain, resulting in limited improvement in smoothness and failing to meet the demands of mid-to-high-end products. If only a sanding polisher is used, its polishing efficiency is low for yarns with high surface roughness, and it cannot completely remove stubborn impurities, easily leading to problems such as yarn breakage and fabric pilling in subsequent production. Therefore, a yarn surface smoothness improvement device with a multi-stage polishing structure was designed. This device first treats the yarn with a ceramic polisher to remove obvious impurities, and then uses a sanding polisher to remove surface roughness, thereby improving the smoothness of the yarn. Utility Model Content

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0024] like Figures 1-4As shown, a yarn surface smoothness improvement device includes a fixed frame 1, a bearing seat 2, a rotating shaft 3, and a first polishing mechanism 4. The fixed frame 1 has a rectangular frame structure, and the rotating shaft 3 is arranged inside the bearing seat 2 at the upper part of the fixed frame 1. The first polishing mechanism 4 is arranged at the lower part of the rotating shaft 3. The first polishing mechanism 4 includes a first polishing group, a second polishing group, and a third polishing group. The first polishing group includes a support 401, a first lever arm 402, a first guide wheel 403, a second guide wheel 404, a third guide wheel 405, and a first polisher 406. The first lever arm 402 is symmetrically arranged at the upper part of the support 401, and the first guide wheel 403, the second guide wheel 404, and the third guide wheel 405 are arranged on the upper part of the first lever arm 402. Yarn is arranged on the first guide wheel 403, and the yarn is connected to the first polisher 406 on the rotating shaft 3. The other end of the yarn is connected to the second polishing group and the third polishing group.

[0025] It should be noted that in the field of yarn processing, in order to improve the quality of yarn, it is necessary to perform a polishing process. In this process, the traditional method usually only performs a polishing operation once, and the burrs on the surface cannot be completely removed, so the quality does not meet the requirements. Based on this, the original polishing equipment has been improved. A first polishing mechanism 4 and a second polishing mechanism 5 are set on the upper part of the fixed frame 1. The first polishing mechanism 4 is equipped with a first polishing group, a second polishing group and a third polishing group, which can perform three polishing processes on the yarn. Moreover, the first polisher 406, the second polisher 408 and the third polisher 409 are all ceramic polishers, which can remove obvious impurities on the surface of the yarn.

[0026] It should be further explained that a first lever arm 402 and a second lever arm are symmetrically arranged on the upper part of the bracket 401. The first lever arm 402 is provided with a plurality of first guide wheels 403 and second guide wheels 404. By the corresponding arrangement of the guide wheels, the yarn can be wrapped on the outer wall of the polisher, so that the polishing operation of the yarn can be realized under the rotation of the polisher.

[0027] like Figures 1-4 As shown, a second polisher 408 is provided in the middle of the second polishing group, and a third polisher 409 is provided in the middle of the third polishing group; a second arm is provided on one side of the first arm 402, and a thread guide wheel 407 is provided on the upper part of the second arm, and the yarn is connected to the second polishing group through the thread guide wheel 407.

[0028] It should be noted that a second and third polishing group are set on one side of the first polishing group, which can polish the yarn three times to improve the polishing effect.

[0029] like Figures 1-5As shown, it also includes a second polishing mechanism 5, which includes a base 501, a third lever arm 502, a rotating shaft 504, a connecting rod 505, and an auxiliary wheel 506. The third lever arm 502 is located on the upper part of the base 501, and the rotating shaft 504 is located in the middle of the two third lever arms 502. The connecting rod 505 and the auxiliary wheel 506 are located on the rotating shaft 504. The auxiliary wheel 506 is movably mounted on one end of the connecting rod 505, and the side of the auxiliary wheel 506 is located at the junction with the yarn 507. The yarn 507 is wrapped around the surface of the fourth polisher. A torsion spring is provided at the connection between the connecting rod 505 and the rotating shaft 504.

[0030] It should be noted that the second polishing mechanism 5 is used for polishing and grinding the yarn. The base 501 has a third lever arm 502 symmetrically arranged on the upper part, and a connecting rod 505 is arranged on the rotating shaft 504 of the third lever arm 502. The auxiliary wheel 506 at one end of the connecting rod 505 is arranged at the point where it contacts the yarn covering the surface of the fourth polisher, and applies pressure to it, thereby increasing the contact strength between the yarn and the surface of the fourth polisher, and realizing the yarn polishing operation.

[0031] It should be further explained that the yarn is wrapped and set on the fourth polisher by the fourth guide wheel 503, and is squeezed and pre-tightened by the auxiliary wheel 506 at one end of the connecting rod 505, thereby increasing the contact pressure with the fourth polisher and improving the polishing effect.

[0032] like Figures 1-4 As shown, a yarn surface smoothness improvement device is characterized in that a first sprocket 9 is provided at one end of the rotating shaft 3, and the first sprocket 9 is connected to a second sprocket 8 on the output shaft of the drive motor 7 through a first transmission chain 6; the fourth polisher is provided on the upper part of the rotating shaft 3.

[0033] The rotating shaft 3 is connected to the drive motor 7 via the first transmission chain 6, thereby enabling the rotation of the rotating shaft 3 and all the grinders to rotate. The rotation speed can be controlled by the controller.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
