Technical Field

[0001] This utility model relates to the field of textile equipment, and in particular to a spinning nozzle for air-jet spinning equipment. Background Technology

[0002] Traditional air-jet spinning equipment typically uses a single-layer nozzle design with a non-replaceable internal yarn guide tube and lacks wear-resistant treatment. This structure easily leads to premature wear of the yarn guide tube during use, affecting yarn quality and limiting the applicability of the equipment. Furthermore, the nozzle needs to be replaced for yarns of different specifications. Since the yarn guide tube is fixedly connected to the nozzle body, any damage requires replacement of the entire unit, increasing maintenance costs and time. Therefore, a new spinning nozzle for air-jet spinning equipment is designed. Utility Model Content

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0013] A spinning nozzle for an air-jet spinning device includes a universal outer nozzle 1, an end sealing gasket 2, and an inner yarn guide tube 3. The inner yarn guide tube 3 is inserted laterally inside the universal outer nozzle 1, and the end sealing gasket 2 is fixed to the end of the universal outer nozzle 1.

[0014] The universal external nozzle 1 is composed of an external air duct 4, an inner yarn guide tube 5, an air duct partition 6, a spiral guide plate 7, a limiting ring 8, and a guide slide 9. The inner yarn guide tube 5 is located inside the air duct partition 6, and the air duct partition 6 is located inside the external air duct 4. The external air duct 4, the inner yarn guide tube 5, and the air duct partition 6 are all aligned with a circular axis. Double-layer jet chambers 10 are provided between the external air duct 4 and the air duct partition 6, and between the air duct partition 6 and the inner yarn guide tube 5. The spiral guide plate 7 is located inside the double-layer jet chambers 10, and the limiting ring 8 is located at the front end of the inner side wall of the inner yarn guide tube 5. The guide slide 9 is provided in multiple sets, which are arranged parallel to each other on the inner sidewall of the inner yarn guide tube 5. The outer air duct 4, inner yarn guide tube 5, air duct partition 6, spiral guide plate 7, limiting ring 8, and guide slide 9 are integrally formed. The end of the inner yarn guide tube 5 is provided with a connecting thread 15. The end sealing gasket 2 is provided at the end of the outer air duct 4, inner yarn guide tube 5, and air duct partition 6, and the end sealing gasket 2 does not block the end opening of the double-layer jet chamber 10. The inner yarn guide tube 3 is inserted into the inner yarn guide tube 5 and is embedded between the guide slide 9.

[0015] The outer wall of the inner yarn guide tube 3 is provided with a guide groove 11, and the guide protrusion 9 is correspondingly embedded in the guide groove 11. The front end of the inner yarn guide tube 3 is closely attached to one side of the limiting ring 8. The front end of the inner yarn guide tube 3 is provided with an outwardly protruding extension tube section 12. The outwardly protruding extension tube section 12 and the inner yarn guide tube 3 are integrally formed. The end of the inner yarn guide tube 3 is provided with an inlet flared mouth 13. The inner sidewall of the inner yarn guide tube 3 and the inner sidewall of the inlet flared mouth 13 are coated with a diamond-like coating 14. The outwardly protruding extension tube section 12 protrudes outward from the front end of the inner yarn guide tube 5.

[0016] In practical applications, the working principle of this spinning nozzle is as follows: Through the design of the double-layer jet chamber 10, the flow of gas between the outer air duct 4 and the air duct partition 6, and between the air duct partition 6 and the inner yarn guide tube 5, is more efficient. The presence of the spiral guide plate 7 further optimizes the airflow distribution, allowing the gas to enter the nozzle more evenly. When the yarn enters the inner yarn guide tube 3 through the inlet bell 13, the diamond-like carbon coating 14 significantly reduces friction, thereby reducing yarn wear during high-speed movement. The design of the outwardly convex extension section 12 enhances the connection stability between the yarn guide tube 3 and the overall nozzle structure, while ensuring smooth movement of the yarn at the outlet end of the yarn guide tube 3, reducing contact wear between the nozzle and the yarn. The cooperation between the guide groove 11 and the guide protrusion 9 makes the installation and disassembly of the inner yarn guide tube 3 more convenient, while also ensuring its precise positioning during operation. This design not only improves spinning efficiency but also extends the service life of the equipment, providing a more reliable solution for the practical application of air-jet spinning equipment.

[0017] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
