Description

Technical Field

[0001] The utility model relates to the field of cotton yarn cutting, in particular to a cotton yarn fixed-distance cutting device. Background Art

[0002] Cotton yarn is yarn made from cotton fiber through spinning technology, and is called cotton thread after plying. According to different spinning processes, it can be divided into carded yarn and combed yarn. Carded yarn: yarn spun from cotton fiber through ordinary spinning system, combed yarn: yarn spun from cotton fiber through combed spinning system. Combed yarn is made of high-quality raw materials. The fibers in the yarn are straight and parallel, with few knots, good gloss, uniform yarn and high strength. This kind of cotton yarn is mostly used for weaving high-end fabrics. In the processing and production of cotton yarn, the cotton yarn needs to be cut.

[0003] However, in the prior art, due to the lack of an auxiliary fixing structure in the cotton yarn fixed-distance cutting device, this leads to inconsistent position and tension of the cotton yarn during the cutting process, which affects the cutting accuracy. Utility Model Content

[0012] By adopting the above technical solution, by pushing the card plate, the card plate compresses the telescopic rod and the spring, the card plate slides out of the card hole, pulls the cutting knife to one side, and the mounting block slides inside the fixing seat to separate the mounting block and the fixing seat, that is, the cutting knife is disassembled. Similarly, during installation, the mounting block is slid along the inner wall of the fixing seat. When the card plate reaches the position of the card hole, the spring rebounds to make the card plate enter the card hole, and the installation of the cutting knife is completed. The cutting knife can be loaded and unloaded by the card plate, the telescopic rod, the spring, the fixing seat and the card hole, and can be replaced when it is damaged, and the difficulty of replacement can also be reduced.
