Long filament online detectorIt is the core equipment for real-time quality monitoring and intelligent control in chemical fiber production. It provides data support for process optimization and quality control through multi-dimensional parameter detection and intelligent algorithm analysis. Usually, multimodal sensors such as optical, mechanical, and electrical sensors are integrated, combined with machine vision and deep learning algorithms to achieve non-contact dynamic detection. For example, the online intelligent detection system for the appearance of polyester filament roll packaging uses high-resolution industrial cameras and adaptive light sources to capture surface defects (such as fuzz, oil stains, poor molding, etc.) on the roll packaging through image self partitioning technology. Combined with a defect feature library, it achieves a 99.2% correct detection rate with a detection time of ≤ 4.4 seconds per ingot.
Long filament online detectorCore detection function:
1. Surface defect detection
Function:
Detect defects on the surface of the filament, such as fuzz, uneven thickness, holes, cracks, oil stains, color differences, etc.
Support high-precision detection (resolution up to micrometer level), suitable for filaments with different line densities (such as 5-2000 dtex).
Technical means:
Using optical imaging (such as high-resolution industrial cameras), laser scanning, or infrared sensing technology, combined with image processing algorithms to identify defects.
2. Diameter/diameter uniformity detection
Function:
Real time measurement of the diameter changes of the filament, monitoring its uniformity (such as CV value), to avoid subsequent processing problems (such as wire breakage and winding) caused by diameter fluctuations.
Technical means:
Principle of laser diffraction, light and shadow projection, or electromagnetic induction, non-contact measurement of diameter and recording of data.
3. Tension detection
Function:
Monitor the tension value of the filament during the production process to prevent breakage, relaxation, or poor forming caused by excessive or insufficient tension.
Support dynamic tension fluctuation alarm (such as setting upper and lower limit thresholds).
Technical means:
Measure tension through strain gauges, load sensors, or non-contact optical sensors.
