Technical Field

[0001] This utility model belongs to the field of textile machinery manufacturing technology, and relates to the improvement of automatic winding machine, specifically a yarn blowing device. Background Technology

[0002] The yarn blowing device on an automatic winding machine is a device that blows yarn into the yarn blowing tube and is picked up by the yarn suction nozzle when a single spindle of the equipment changes its blowing head.

[0003] The existing yarn blowing device has a complex structure and high processing cost. It requires high assembly precision during assembly. The main principle is to blow air into the yarn tube by the air nozzle, and then the yarn tube suction nozzle sucks it up for subsequent twisting process.

[0004] In terms of processing and manufacturing costs, pass rate, ease of assembly process, and the special characteristics of special yarn varieties, the current yarn blowing device mainly relies on a single main air blower to blow and guide the yarn. However, this action cannot guarantee the success rate of blowing and guiding the yarn every time, and the overall assembly time is relatively long.

[0005] How to design a yarn-drawing blower device that, while ensuring the air-blowing head, incorporates an internal structure with auxiliary air-blowing components to facilitate yarn intake by the yarn suction nozzle during main air blowing, while also ensuring low manufacturing difficulty and cost, and simple assembly, is a pressing technical problem that needs to be solved in this field. Summary of the Invention

Through the matching auxiliary blowing configuration within its internal structure, the yarn can be more easily picked up and sucked into the tube nozzle by the auxiliary blowing in conjunction with the main blowing. Furthermore, the parts are easy to manufacture and cost to produce, are simple to assemble, and can ensure the success rate of yarn drawing by the blower.

[0007] The objective of this utility model is achieved through the following technical solution: A yarn guiding and blowing device includes a fixed plate, a yarn guiding tube, an air blowing tube, a yarn guiding tube base, and a base sleeve.

The upper part of the base sleeve is inserted into the lower part of the yarn guide tube base. An oblique air blowing hole is provided inside the yarn guide tube base. The lower end of the oblique air blowing hole passes through the through-hole for insertion and communicates with the interior of the lower end of the air blowing tube. The upper end of the oblique air blowing hole passes through the through-hole for insertion and communicates with the interior of the yarn guide tube.
