Description

Technical Field

[0001] The utility model relates to the technical field of cotton yarn shearing lines, and more specifically to an anti-entanglement fine-pile cotton combed yarn shearing device. Background Art

[0002] Cotton yarn is yarn made from cotton fiber through a spinning process, and is called cotton thread after plying. According to different spinning processes, it can be divided into carded yarn and combed yarn. Carded yarn is yarn spun from cotton fiber through an ordinary spinning system, while combed yarn is yarn spun from cotton fiber through a combed spinning system. However, existing yarn shearing devices generally have the problem of low shearing efficiency, which requires users to spend more time to complete the cutting of the yarn, thereby affecting the user's subsequent yarn processing efficiency.

[0003] After searching, a Chinese patent with publication number CN216585386U discloses a yarn shearing device for yarn production. The structure is provided with a telescopic push rod and a shearing knife. When the user needs to ensure the shearing efficiency of the yarn, the shearing knife arranged on the outer wall of the slide rod slides along the slide rod through the movable groove, so that the movable groove arranged at the bottom of the shearing knife rotates along the adjustment block fixed on the inner wall of the support frame, so that the shearing knife shears and completes the cutting of the yarn, thereby ensuring the stability of the user's yarn cutting, improving the user's yarn cutting efficiency, and increasing the practicality of the overall device.

[0004] However, in actual use, during the production of cotton yarn, the produced cotton yarn needs to be reeled in, and after the reeling is completed, it needs to be cut and the cut cotton yarn needs to be rewound onto a new bobbin. After the structure cuts the yarn, the broken end of the cotton yarn needs to be manually wrapped around the outside of the bobbin and the cotton yarn is rewound by the control machine rotation. At the same time, the cotton yarn needs to be continuously pressed by the fingers to prevent the cotton yarn from falling off. During the operation, the fingers can easily be wrapped around the cotton yarn and rotated on the bobbin, causing safety hazards and reducing work efficiency. Utility Model Content
