AI Technical Summary

Technical Problem

Traditional air-jet spinning machines rely on manual judgment of yarn bobbin fullness in their doffing and pushing devices, resulting in inconsistent yarn bobbin winding amounts and affecting the stability of subsequent processing.

Method used

A pressure sensor is used to detect the pressure value on the yarn tube. Combined with a motor and an electric telescopic rod, the extension and replacement of the yarn tube are automatically controlled to ensure consistent yarn winding.

Benefits of technology

It enables precise control and automated replacement of yarn quantity on yarn bobbins, improving the uniformity of yarn winding and the continuity of production.
