Description

Technical Field

[0001] The utility model relates to the technical field of spandex processing, and more specifically, to a spandex yarn let-off device. Background Art

[0002] Spandex yarn, full name spandex fiber, is short for polyurethane fiber and is a modern clothing industry material. In the weaving process, the warp beam of elastic bandage spandex yarn is pulled by a motor, and the rotation of the warp beam is controlled by an external gear of the warp beam to realize the feeding of spandex yarn. However, in the process of using the existing spandex yarn let-off device, the diameter of the roller around which the spandex yarn is wound will become smaller and smaller as the spandex yarn decreases. Therefore, under the condition of constant speed, the let-off amount of the warp beam for one revolution will slowly change. For example, the spandex yarn let-off device disclosed in the prior art publication number (CN214328044U) drives the first roller and the second roller through a transmission mechanism, so that the warp beam roller rotates to facilitate the release of spandex yarn. Since the linear speeds of the first roller and the second roller are constant, even as the diameter of the warp beam roller becomes smaller, the outer side of the warp beam roller remains tangent to the first roller and the second roller. Therefore, the warp beam roller always maintains the same linear speed as the first roller and the second roller, thus ensuring the stability of the spandex yarn let-off amount without debugging during the production process.

[0003] When the above device is in use, by making the warp beam roller always fit with the surfaces of the first roller and the second roller, the release speed of the spandex yarn on the warp beam roller is always kept stable, without the need for frequent manual adjustment, realizing production standardization. However, it can only control the release speed of a part of the spandex yarn on the surface of the warp beam roller, and it is inconvenient to replace the warp beam roller again after the release is completed, which affects the release and let-off efficiency of the warp beam roller. Summary of the Utility Model
