Description

Technical Field

[0001] The utility model belongs to the technical field of a core yarn positioning device for woolen coarse spinning spandex core-spun yarn, and more specifically, particularly relates to a core yarn positioning device for woolen coarse spinning spandex core-spun yarn. Background Art

[0002] Core-spun yarn is generally made of synthetic fiber filaments with good strength and elasticity as the core yarn, and short fibers such as cotton, wool, and viscose are twisted together to make yarn. Core-spun yarn has the excellent properties of filament core yarn and short fibers. The more common core-spun yarns include polyester-cotton core-spun yarn, which uses polyester filaments as the core yarn and cotton fibers as the outer yarn. There is also spandex core-spun yarn, which uses spandex filaments as the core yarn and is made of other fibers as the outer yarn. The knitted fabric or jeans made of this core-spun yarn can be stretched and retracted freely when worn, and are comfortable and fit. Among them, the Chinese patent number: CN218436066U discloses a core yarn positioning device for wool-spun spandex core-spun yarn, including a base, the upper side wall of the base is symmetrically fixedly connected with a vertical plate, the tops of the two vertical plates are commonly fixedly connected with a mounting plate, the rear side wall of the mounting plate is fixedly connected with a vertical plate, the front side wall of the vertical plate is rotatably connected with a guide wheel, the front side wall of the vertical plate is slidably inserted with a moving plate, and the outer wall of the moving plate is symmetrically fixedly connected with a connecting plate located on the front side of the vertical plate. The utility model completes the rapid positioning of the core-spun yarn through the coordinated use of two guide cylinders, so that the core-spun yarn can be inserted and removed in a fixed direction during processing, thereby ensuring the quality after processing, and the moving plate, the guide cylinder and the core-spun yarn move backward or forward to achieve the adjustment of the yarn outlet position at the front and rear positions of the core-spun yarn, thereby meeting the production needs and improving the convenience of production.

[0003] Based on the above, the inventors found that there are the following problems: the above patent can complete the rapid positioning of the core-spun yarn through the coordinated use of two guide cylinders, so that the core-spun yarn can be inserted in and out in a fixed direction during processing, thereby ensuring the quality after processing, and the movable plate, guide cylinder and core-spun yarn move backward or forward to adjust the yarn outlet position at the front and rear positions of the core-spun yarn, thereby meeting production needs and improving production convenience. However, when the wire is broken, the staff needs to re-insert the core-spun yarn into the two guide cylinders. Since the through groove in the guide cylinder is small in size and the core-spun yarn is soft in texture, the process of inserting the core-spun yarn into the two guide cylinders is time-consuming, which reduces work efficiency.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a core yarn positioning device for wool-spinning spandex core-spun yarn is provided, in order to achieve the purpose of having more practical value. Utility Model Content
