Description

Technical Field

[0001] The utility model relates to the technical field of vortex spinning, in particular to a vortex spinning air intake device. Background Art

[0002] The vortex spinning air intake device is an important part of the vortex spinning machine. It is responsible for providing the necessary airflow to the vortex spinner to form a vortex and complete the spinning process. The main function of the vortex spinning air intake device is to provide a stable and adjustable airflow for the vortex spinner. By controlling the speed and flow of the airflow, it can affect the fiber coagulation and twisting effect in the vortex spinning process, thereby controlling the quality and production efficiency of the yarn.

[0003] Traditional vortex spinning air intake devices often lack air filtration and slow flow treatment when introducing external air, resulting in impurities in the air directly entering the vortex spinning system, which not only affects the cleanliness of the yarn, but may also cause damage to the precision components inside the spinning machine. Untreated air directly enters the vortex tube, and the instability of the airflow may cause fluctuations in yarn quality and reduce production efficiency. For this reason, we proposed a vortex spinning air intake device. Utility Model Content

[0033] Furthermore, the airflow stabilizing device 15 includes an air inlet pipe 6, a vortex air inlet 11 and a vortex tube 13. The upper end of the yarn entrance channel 9 is fixedly connected to the air inlet pipe 6, and the outer side surface of the air inlet pipe 6 is fixedly connected to three air inlet blocks arranged in a ring shape and at equal distances. Two vortex air inlets 11 symmetrically arranged in the upper and lower parts are provided on the three air inlet blocks. Three groups of vortex tubes 13 equidistantly distributed in a ring shape are provided on the inner wall of the air inlet pipe 6, and the number of vortex tubes 13 in each group is two.

[0035] Working principle: First, air enters through the opening of the air intake device housing 1, and a fan can be set on the outside. When the air enters, the first barrier encountered is the air filter plate 4. The air filter plate 4 is made of fiberglass board material. The multiple filter holes opened on it effectively remove dust, particles and impurities in the air, providing a clean air source for the spinning process. The filtered air enters the inner cavity of the air intake device housing 1, and the airflow enters the air inlet pipe 6, where an airflow stabilizing device 15 is set. Three air inlet blocks arranged in an annular shape and equidistant are fixed on the outside of the air inlet pipe 6. Two symmetrical vortex air inlets 11 are opened on these air inlet blocks. The function of the vortex air inlet 11 is to regulate and stabilize the incoming airflow to prevent excessive airflow fluctuations from affecting the spinning quality. At the same time, three groups of vortex tubes 13 distributed in an annular shape and equidistant are opened on the inner wall of the air inlet pipe 6, and each group contains two vortex tubes. The function of these vortex tubes 13 is to guide the airflow to form a vortex, increase the rotation and turbulence of the airflow, and further promote the uniform spinning of the yarn. The air distribution channel 12 in the air inlet block guides the airflow to the vortex tube 13, ensuring that the airflow can be evenly distributed to each vortex tube. The yarn enters the spinning nozzle 3 through the yarn inlet 8 and the yarn inlet channel 9. Inside the spinning nozzle 3, the yarn is affected by the vortex airflow generated by the vortex tube 13, and is evenly spun with the cooperation of the needle-shaped twist block 10. The vortex airflow not only helps the yarn to be spun smoothly, but also effectively reduces the breakage and knotting of the yarn, thereby improving the continuity and quality of spinning.
