Description

Technical Field

[0001] The utility model belongs to the technical field of textile machinery manufacturing, relates to the improvement of an automatic winder, and specifically relates to an automatic winder with a yarn guiding device. Background Technique

[0002] On a yarn winding device, in order to effectively control the excessive fluctuation of the yarn during the yarn unwinding process and stabilize the tension, when the yarn is unwound, a slender tube is used to control the unwinding wave band of the yarn. However, when the yarn passes through the slender tube, there will be a problem that it is not easy to pass through, which affects the head feeding efficiency.

[0003] Precisely because of the continuous optimization of the unwinding process, the requirement for the length of the yarn guiding distance is continuously increasing. For a long distance and a small inner diameter of the yarn guiding tube, especially for special yarn varieties, relying on a single main blowing often cannot reliably complete each blowing head and yarn guiding action. An auxiliary blowing structure needs to be added, and the previous single-airway auxiliary blowing can no longer ensure the reliability of the blowing head.

[0004] In the existing structure, the bottom of the main pipe can be connected by means of threads or the like to form a bottom chamber, and then the blowing holes are penetrated upward to blow air upward. This method can only blow air upward from the bottom, and it is not very easy to guide the yarn for a long tube.

[0005] How to design an automatic winder with a yarn guiding device that can effectively and reliably allow the yarn to pass through the slender channel to complete each blowing head and yarn guiding action, and has a reasonable structure design, can significantly reduce the part processing and manufacturing difficulty and the scrap rate. This is an urgent technical problem to be solved in this field. Content of the Utility Model
