Airflow twisting device used for weaving and with filter screen being convenient to replace

Abstract

The invention relates to an airflow twisting device used for weaving and with a filter screen being convenient to replace. The airflow twisting device is used for twisting rough yarns, and comprises a vortex airflow twisting unit (5), the vortex airflow twisting unit (5) comprises an annular body portion (53) and an annular housing portion (54), the interior of the annular body portion (53) is provided with a cylindrical vortex air chamber (50), the annular housing portion (54) is integrally molded and accommodates the annular body portion (53), the annular body portion (53) is provided with a plurality of tangential airways (51) which are uniformly distributed along the circumferential direction in order to input airflow along the tangential direction of the cylindrical vortex air chamber (50), and an annular airflow distribution chamber (540) is arranged between the annular housing portion (54) and the annular body portion (53).

Description

technical field [0001] The application relates to the field of textile machinery, in particular to an air-twisting device for textile use which facilitates the replacement of filter screens. Background technique [0002] In the textile field, the twisting of the roving is often carried out by swirling air. Such a swirling airflow can be achieved by swirling in the swirling chamber with a plurality of tangentially supplied airflows. [0003] However, as the number of airflow passages in the tangential direction increases and the diameter of the passages decreases, the blockage of the airflow passages is more likely to occur. [0004] Due to the characteristics of the high-speed operation of the airflow and the large number of airflow passages, the blockage of the airflow passages is often not easy to be found and cannot be overcome or corrected immediately. This leads to quality defects in continuous textile production. Downtime for maintenance reduces productivity and cre...

AI Technical Summary

Problems solved by technology

[0003] However, with the increase of the airflow passages in the tangential direction and the reduction of the diameter of the passages, the blockage of the airflow passages is more likely to occur.

[0004] Due to the characteristics of the high-speed operation of the airflow and the large number of airflow channels, the blockage of the airflow channel is often not easy to be found and it is not easy to overcome or correct it immediately.

This leads to quality defects in continuous textile production

Downtime for maintenance reduces productivity and incurs additional production costs
