[0002] In existing technology, cotton yarn is a basic material used to manufacture various textiles. It is made from fibers extracted from cotton through a spinning process. Spinning is the process of separating cotton fibers and winding them together to form yarn. The spun cotton yarn can be classified according to characteristics such as fiber length, thickness, and quality, commonly including different grades such as roving, medium yarn, and fine yarn.

[0003] Chinese Patent CN220264709U discloses a textile cotton yarn lapping machine, comprising a housing. Several first hangers are fixedly connected to both sides of the inner wall of one end of the housing. A feeding roller is rotatably connected to each of the first hangers. Several slide rails are fixedly connected to the inner wall of the housing end near the first hangers. A flattening mechanism is slidably connected to each of the slide rails. A pair of second hangers are fixedly connected to both sides of the housing end away from the first hangers. A receiving roller is rotatably connected to the pair of second hangers. This invention improves the quality of the cotton yarn lapped by using a flattening mechanism, a pressing mechanism, and a collection box, while preventing flyaway fibers from causing machine jamming or worker injury.

[0004] However, the device still has shortcomings: it cannot clean impurities or dust on the surface of cotton yarn during use, which will affect the production quality of cotton yarn to some extent during processing. Utility Model Content

[0005] This application provides a device for removing impurities from the surface of textile yarn, which solves the problem that the existing device cannot clean impurities or dust on the surface of cotton yarn during use, thus affecting the production quality of cotton yarn to some extent during processing.

[0006] The technical solutions adopted in the embodiments of this application are as follows.

[0007] A device for removing impurities from the surface of textile yarn includes a housing, a brush head for dust removal from the yarn surface, an adjusting device for adjusting the pressure between the brush head and the yarn, a dust removal pipe for extracting dust swept from the yarn, and a cover plate for easy maintenance.

The adjusting device is located in the dust removal zone, and the brush head is located on both its upper and lower operating ends. Two sets of brush heads are arranged opposite each other, with the two sets of brush heads either close to or far from the yarn. One end of the dust removal pipe is connected to the dust removal zone, and the other end is connected to a fan.

[0008] As a further improvement to the above technical solution: the cover plate is fixed to the housing by bolts.

[0009] As a further improvement to the above technical solution: threading holes are provided on the surface of the housing corresponding to the cover plate and on the cover plate; the yarn passes through two sets of threading holes; and rounded corners are provided at the threading holes to prevent the yarn from breaking.

[0010] As a further improvement to the above technical solution: the adjustment device includes a guide rod, a first block sliding on the guide rod, a second block disposed on the first block, a moving rod for driving the first block to move up and down, and a driving member for driving the moving rod to rotate; the driving member is disposed on the housing; the moving rod is disposed opposite to the guide rod; the first block and the second block are disposed mirror images of the yarn; the moving rod drives the two sets of first blocks to move closer or further apart; the moving rod is a bidirectional screw.

[0011] As a further improvement to the above technical solution: a limiting block is provided on the second block; the limiting block is convex in shape; a limiting groove corresponding to the limiting block is opened on the brush head; the limiting block and the limiting groove correspond; the brush head is detachably connected to the second block.

[0012] As a further improvement to the above technical solution: a baffle is provided on the second block; an elastic element is provided on the baffle; a pressing block is slidably connected to the limiting block; the pressing block abuts against the elastic element; a locking block is hinged to one end of the second block away from the baffle; the locking block corresponds to the side wall of the brush head and a locking groove is provided on the side wall of the brush head; when the locking block is inserted into the locking groove, the elastic element is compressed so that the locking block always restricts the brush head to be located on the second block.

[0013] As a further improvement to the above technical solution: the yarn is transmitted from the elastic element toward the card block.

[0014] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0015] 1. The design utilizes a moving rod driven by a bidirectional screw, linked to a mirror-symmetrical adjustment device, to achieve synchronous, stepless adjustment of the distance between the upper and lower brush heads. This structure is adaptable to textile yarns of different diameters. Through mechanical transmission, it precisely controls the contact pressure between the brush head and the yarn, efficiently removing surface impurities while avoiding fiber damage due to excessive pressure, thus balancing cleaning effectiveness and yarn integrity. A composite locking structure combining a convex-shaped limiting block and an elastic clamping block, along with a beveled self-locking design of the locking block and slot, ensures stable fixation of the brush head under high-speed yarn transmission and vibration conditions. The continuous clamping force of the elastic element keeps the brush head and the second block in close contact, effectively preventing loosening due to impact during operation. The brush head can be disassembled and assembled in seconds via a quick-connect structure of the limiting slot and locking block. Combined with an open maintenance window formed by a removable cover, this significantly simplifies the internal component replacement process. Compared to traditional fixed structures, this design significantly reduces equipment downtime for maintenance and improves production continuity. The dust collection pipe and fan work together to create a directional negative pressure airflow, which, combined with the sealed dust collection zone structure, ensures that dust swept off by the brush head is immediately removed. The rounded corner design of the threading holes effectively reduces frictional resistance when the yarn passes through, minimizing fiber damage and dust dispersion while ensuring dust collection efficiency.

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

The housing 1 has a dust removal zone 11 inside, with one end of the dust removal zone 11 being open. The cover plate 6 is detachably connected to the opening of the dust removal zone 11. The adjusting device 4 is located in the dust removal zone 11, and brush heads 2 are provided on both its upper and lower working ends. Two sets of brush heads 2 are arranged opposite each other, with the two sets of brush heads either close to or far from the yarn. One end of the dust removal pipe 5 is connected to the dust removal zone 11, and the other end of the dust removal pipe 5 is connected to a fan.

[0024] The cover plate 6 is fixed to the housing 1 by bolts.

[0025] Both the housing 1 and the cover plate 6 have threading holes 7 on their corresponding surfaces; the yarn passes through two sets of threading holes 7; and the threading holes 7 are rounded to prevent the yarn from breaking.

[0026] The adjusting device 4 includes a guide rod 41, a first block 42 sliding on the guide rod 41, a second block 43 disposed on the first block 42, a moving rod 44 that drives the first block 42 to move up and down, and a driving member 45 that drives the moving rod 44 to rotate; the driving member 45 is disposed on the housing 1; the moving rod 44 is disposed opposite to the guide rod 41; the first block 42 and the second block 43 are disposed in mirror image relative to the yarn; the moving rod 44 drives the two sets of first blocks 42 to move closer or further apart; the moving rod 44 is a bidirectional screw.

[0027] The second block 43 is provided with a limiting block 431; the limiting block 431 is convex in shape; the brush head 2 is provided with a limiting groove 21 corresponding to the limiting block 431; the limiting block 431 corresponds to the limiting groove 21; the brush head 2 is detachably connected to the second block 43.

[0028] The second block 43 is provided with a baffle 432; the baffle 432 is provided with an elastic element 433; a pressing block 434 is slidably connected to the limiting block 431; the pressing block 434 abuts against the elastic element 433; a locking block 435 is hinged to the end of the second block 43 away from the baffle 432; the locking block 435 corresponds to the side wall of the brush head 2 and a slot 22 is provided on the side wall of the brush head 2; when the locking block 435 is inserted into the slot 22, the elastic element 433 is compressed so that the locking block 435 always restricts the brush head 2 to be located on the second block 43.

[0029] The yarn is transmitted from the elastic element 433 toward the locking block 435.

[0030] The synchronous stepless adjustment of the distance between the upper and lower brush heads 2 is achieved by using a moving rod 44 driven by a bidirectional screw and linked with a mirror-symmetrical adjustment device 4. This structure can adapt to textile yarns of different diameters. Through mechanical transmission, it precisely controls the contact pressure between the brush head 2 and the yarn, effectively removing surface impurities while avoiding fiber damage due to excessive pressure, thus balancing cleaning effect and yarn integrity. The composite locking structure of the convex-shaped limiting block 431 and the elastic pressing block 434, combined with the inclined self-locking design of the locking block 435 and the slot 22, ensures that the brush head 2 is stably fixed under high-speed yarn transmission and vibration. The continuous pressing force of the elastic element 433 keeps the brush head 2 and the second block 43 in close contact at all times, effectively preventing loosening caused by impact during operation. The quick-connect structure of the limiting slot 21 and the locking block 435 allows for second-level disassembly and assembly. Combined with the open maintenance window formed by the removable cover plate 6, the internal component replacement process is significantly simplified. Compared to traditional fixed structures, this design significantly reduces equipment downtime for maintenance and improves production continuity. The dust collection pipe 5 works in conjunction with the fan to create a directional negative pressure airflow, which, combined with the sealed dust collection zone 11, ensures that the dust swept off by the brush head 2 is immediately removed. The rounded corner design of the threading hole 7 effectively reduces the frictional resistance of the yarn as it passes through, minimizing fiber damage and dust dispersion while ensuring dust collection efficiency.
