Description

Technical Field

[0001] This utility model relates to the field of airflow optimization technology, specifically to an airflow optimization device for the spinning cup of an airflow spinning machine. Background Technology

[0002] In modern textile industry, air-jet spinning has become one of the important technologies for short fiber spinning due to its advantages of high output, high efficiency, and low cost. The core component of an air-jet spinning machine is the spinning cup, which, through the action of internal airflow, cohedes the single fibers separated by the combing rollers into slivers and twists them into yarn. The state of the airflow within the spinning cup directly determines the fiber cohesion effect, twisting quality, and key indicators such as yarn strength and evenness. Therefore, optimizing the airflow within the spinning cup is a crucial step in improving yarn quality and increasing production efficiency.

[0003] The prior art discloses a spinning cup for an air-jet spinning machine, with announcement number CN208071874U. The cup includes a cup body and a cup rod connected to each other. The cup body includes a cup mouth and a cup bottom connected to each other. The cup mouth is a tapered cone shape. A V-shaped condensing groove is provided at the connection between the cup mouth and the cup bottom. A connecting groove is provided at the center of the cup bottom. The cup rod is installed in the connecting groove. An inverted truncated cone-shaped recess is provided on the cup bottom along the periphery of the connecting groove. The recess includes a first inclined surface near the condensing groove and a second inclined surface near the connecting groove. The inclination of the first inclined surface is greater than that of the second inclined surface. Several exhaust holes are provided on the recess. The exhaust holes are located at the intersection of the first and second inclined surfaces, and the outlet of the exhaust holes extends to the outer surface of the cup body.

[0004] The aforementioned airflow optimization device for the spinning cup of the air-jet spinning machine can reduce the accumulation of short fibers around the exhaust hole, ensure timely airflow discharge from the exhaust hole, and improve production efficiency. However, the spinning cup of the aforementioned airflow optimization device does not have an airflow adjustment component inside, which cannot improve the airflow distribution and stability inside the spinning cup. As a result, the quality and output of the yarn are insufficient, and the effect during use is not good. Improvement is needed. Utility Model Content

The pointer 311 is slidably connected to the inner ring of the scale ring 314 near the front. A bearing is fixedly connected to the inner ring of the connecting round seat 307 near the front. The inner diameter of the bearing is adapted to the diameter of the connecting post 309. The magnetic slider 310 is slidably connected to the front of the magnetic ring 308. The magnetic slider 310 is magnetically connected to the magnetic ring 308. The magnetic slider 310 slides against the front of the magnetic ring 308.

[0026] The airflow stabilizing assembly 4 includes a mounting base 401, an inlet ring 402, a first guide cone 403, an elastic diaphragm 404, a second guide cone 405, and an outlet pipe 406. The mounting base 401 is fixedly connected to the inside of the spinning cup 1 near the bottom. The inlet ring 402 is fixedly connected to the top of the mounting base 401.

This, combined with the first guide cone 403 and the second guide cone 405, guides the airflow, ensuring it flows out from below.
