AI Technical Summary

⚠Technical Problem

In the existing technology, the detection device for hollow fiber spinnerets cannot acquire individual airflow data for each arc-shaped slit, leading to false detections and failing to ensure the uniformity of the spinneret holes.

⚗Method used

A detection device was designed, which introduces air into each spinneret hole through the detection section and uses a sensor assembly to detect the gas flow rate. Combined with a drive motor and control module, the gas flow rate of each individual spinneret hole is determined.

🎯Benefits of technology

It achieves precise gas flow acquisition for each spinneret orifice, avoids false detections, and ensures the accuracy of spinneret orifice uniformity detection.

Abstract

The present application belongs to the technical field of measurement, and particularly relates to gas flow measurement, and especially relates to a detection device for a hollow fiber spinneret and a working method thereof. The detection device for the hollow fiber spinneret is provided with a detection part, which is used for sequentially ventilating each spinning hole when detecting the spinning hole at a spinning position, and the remaining spinning holes are blocked when one spinning hole is ventilated. A control module is used for controlling a sensor assembly to detect the gas flow of each spinning hole, so as to determine whether each spinning hole is qualified, and the gas flow of a single spinning hole is obtained, and it is convenient to accurately determine whether each spinning hole is qualified.
