Description

Technical Field

[0001] This utility model relates to a spinning device for spinning spandex yarn, belonging to the field of spandex yarn technology. Background Technology

[0002] Spandex is a synthetic fiber with excellent elasticity and high resilience. Its main component is polyurethane, hence it is also known as "Lycra". Spandex is widely used in elastic fabrics such as underwear, swimwear, sportswear, and socks, which can significantly improve the comfort and fit of the fabric. Because spandex itself has low strength and is easy to break when used directly, it is usually compounded with other fibers (such as cotton, polyester, or nylon) during processing to balance elasticity and strength. Therefore, a doubling device is required for doubling.

[0003] However, in the use of existing spandex yarn doubling devices, the distance between the two guide wheels cannot be flexibly adjusted. Since different specifications of spandex yarn or composite yarn have different tension requirements, a fixed distance may lead to uneven tension control, causing the spandex yarn to be too loose or too tight. This can easily lead to fiber entanglement, knotting, or delamination during doubling, affecting the yarn quality.

[0004] Therefore, a twisting device for the twisting processing of spandex yarn is proposed. Utility Model Content

[0005] In view of this, the present invention provides a spinning device for the spinning of spandex yarns, so as to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0006] The technical solution of this utility model is implemented as follows: A spinning device for processing spandex yarns includes a housing. A first connecting block is fixedly installed on the rear side of the housing. A winding roller is movably connected to the inner side of the first connecting block. An adjustment assembly is provided on the inner side of the housing. The adjustment assembly includes a first servo motor, a threaded rod, a threaded sleeve, a support rod, a guide ring, a limit block, a guide block, and a guide groove. The threaded rod is movably connected to the inner side of the housing. The threaded sleeve is threadedly connected to the left and right sides of the surface of the threaded rod. The support rod is fixedly connected to the top of the two threaded sleeves. The guide ring is fixedly connected to the top of the two support rods.

[0007] More preferably, the first servo motor is fixedly connected to the front side of the housing, and the threaded rod is fixedly connected to the output end of the first servo motor.

[0010] More preferably, the top of the box is bolted with a cover plate, the surface of which has a through groove, and the support rod passes through the through groove and extends to the outside of the box.

[0011] More preferably, the cover plate is designed to be detachable, allowing for quick disassembly and maintenance using conventional tools when needed.

[0012] More preferably, an L-shaped plate is fixedly installed on the left side of the housing, a second connecting block is fixedly installed on the surface of the L-shaped plate, a second servo motor is fixedly installed on the front side of the second connecting block, a take-up roller is movably connected to the inner side of the second connecting block, and the take-up roller is fixedly connected to the output end of the second servo motor.

[0023] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] Example 1

[0026] like Figure 1-4 As shown, this utility model embodiment provides a spinning device for processing spandex yarns, including a housing 1. A first connecting block 2 is fixedly installed on the rear side of the housing 1. A winding roller 3 is movably connected to the inner side of the first connecting block 2. An adjusting component 4 is provided inside the housing 1. The adjusting component 4 includes a first servo motor 401, a threaded rod 402, a threaded sleeve 403, a support rod 404, a guide ring 405, a limiting block 406, a guide block 407, and a guide groove 408. The threaded rod 402 is movably connected to the housing 1. Inside the housing, threaded sleeves 403 are threadedly connected to the left and right sides of the surface of threaded rod 402. Support rods 404 are fixedly connected to the tops of the two threaded sleeves 403. Guide rings 405 are fixedly connected to the tops of the two support rods 404. The first servo motor 401 is fixedly connected to the front side of the housing 1. The threaded rod 402 is fixedly connected to the output end of the first servo motor 401. Limiting blocks 406 are fixedly connected to the left and right sides of the surface of threaded rod 402, and the diameter of the limiting blocks 406 is larger than the diameter of the threaded sleeves 403.

[0027] By adjusting the settings of component 4, during the spline processing of spandex yarn, the first servo motor 401 drives the threaded rod 402 at the output end to rotate. Under the action of the threaded connection, the threaded sleeve 403, support rod 404 and guide ring 405 move laterally, thereby adjusting the spacing between the guide rings 405. This can adapt to the processing requirements of spandex yarn of different specifications, avoiding uneven wrapping due to excessive looseness or yarn breakage due to excessive tightness.

[0028] Example 2

[0029] In one embodiment, the guide block 407 is fixedly connected to the bottom of the threaded sleeve 403, the guide groove 408 is opened at the bottom of the inner cavity of the housing 1, the guide block 407 is slidably connected to the inner side of the guide groove 408, the top of the housing 1 is bolted with a cover plate 5, the surface of the cover plate 5 is provided with a through groove 6, the support rod 404 passes through the through groove 6 and extends to the outside of the housing 1, the cover plate 5 is detachable and can be quickly disassembled and maintained with conventional tools when needed, an L-shaped plate 7 is fixedly installed on the left side of the housing 1, a second connecting block 8 is fixedly installed on the surface of the L-shaped plate 7, a second servo motor 9 is fixedly installed on the front side of the second connecting block 8, a take-up roller 10 is movably connected to the inner side of the second connecting block 8, and the take-up roller 10 is fixedly connected to the output end of the second servo motor 9.

[0030] The guide block 407 and guide groove 408 serve as guides to ensure that the threaded sleeve 403 moves along a predetermined trajectory. The through groove 6 improves the stability of the support rod 404 during movement. The second servo motor 9 and take-up roller 10 can be used to take up and merge the yarn after it has been twisted together.

[0031] When this invention is in operation: different yarns are wound onto the surface of the winding roller 3 and passed through the inner side of the guide ring 405. At the same time, the two yarns are combined and wound onto the surface of the take-up roller 10. At this time, the first servo motor 401 can be started to drive the threaded rod 402 at the output end to rotate. During the rotation, the threaded rod 402 drives the threaded sleeve 403 to move laterally through the threaded connection, thereby driving the support rod 404 and the guide ring 405 to move laterally. When it moves to the appropriate position, the second servo motor 9 can be started to drive the take-up roller 10 at the output end to rotate, thereby performing the yarn winding process.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
