Dual-Channel Needle Detector Controller for Circular Knitting Machines
The needle detector controller is a critical quality control device that monitors knitting needles in real time. It instantly detects broken needles, bent needles and hook needles, and automatically stops the machine to prevent defective fabric and costly production losses.
Core Working Principle
The controller uses high-sensitivity inductive sensors to monitor the condition of knitting needles. When a needle breaks or deforms, the sensor detects the abnormal signal and triggers an immediate machine stop, preventing the damaged needle from scratching the fabric or causing further machine damage.
Core Functions
- Dual independent detection channels for simultaneous monitoring of cylinder and dial needles
- High-sensitivity detection of broken needles, bent needles and hook needles
- Instant automatic machine stop with visual and audible alarm
- Adjustable detection sensitivity for different needle types and gauges
- Integrated auto-clean function to remove lint and debris from sensors
Product Advantages
- Dual-Channel Design: Monitors both upper and lower needles simultaneously, providing full protection
- High Sensitivity: Detects even the smallest needle fragments as small as 1mm
- Easy Installation: Comes with a universal mounting bracket, fits all major circular knitting machine brands
- Stable Performance: Anti-interference design ensures reliable operation in textile workshop environments
- Digital Display: Clear LED display for easy parameter setting and status monitoring
