Airflow twisting device provided with filter net and driven by lifting motor to lift for textile

Abstract

The invention discloses an airflow twisting device provided with a filter net and driven by a lifting motor to lift for textile. The airflow twisting device is used for twisting a thick yarn and comprises a vortex airflow twisting device (5), wherein the vortex airflow twisting device (5) comprises an annular body part (53) and an annular housing part (54), wherein a cylindrical vortex air chamber (50) is arranged in the annular body part (53); the annular housing part (54) and the annular body part (53) are integrally molded; the annular housing part (54) accommodates the annular body part (53); a plurality of tangential airways (51) which are evenly distributed along the peripheral direction are formed in the annular body part (53) to input the airflow along the tangential direction of the cylindrical vortex air chamber (50); and an annular airflow distribution chamber (540) is formed between the annular housing part (54) and the annular body part (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 is lifted and lowered by a lifting motor and equipped with a filter. 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 reduce...

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
