Description

Technical Field

[0002] Yarn fixed-length cutting technology is widely used in the textile industry to accurately cut yarn according to the set length to ensure length consistency and production efficiency in subsequent processes. At present, the yarn cutting methods and devices in the prior art are mostly manually or semi-automatically controlled, with problems such as low operating efficiency, insufficient precision and large yarn wear. In addition, many existing devices rely on mechanical shearing tools, which have obvious limitations in cutting accuracy and cutting length, especially in the face of large-scale production, and are prone to errors, and cannot achieve high-precision fixed-length cutting. These technical problems not only affect production efficiency, but also bring about a high scrap rate, increase the waste of raw materials and production costs. Insufficient shearing accuracy will directly affect the quality of textile products, resulting in poor product consistency, which in turn affects the market competitiveness of products. In addition, low operating efficiency and frequent equipment maintenance requirements also increase the operating costs of enterprises and reduce production benefits.
