Needle detectors, also called needle detectors and needle detectors, are mainly used for textile ferromagnetic metal foreign body detection and textile broken needle detection. Next, let's understand the working principle and daily maintenance of needle detector with Shanan Technology.
Working principle of needle detector:
The magnet in the upper and lower magnetic heads and the needle detection coil are combined with the power supply of the machine to form a needle detection magnetic field. Causes local current instantaneous magnetic field fluctuations. The detected abnormal current will be transmitted to the control circuit board and compared with the previously set needle detection sensitivity; when this changed current value reaches or exceeds the needle detection sensitivity value set by the device during use, The control circuit board will issue a series of instructions such as alarm, stop and belt rewind to the machine; and finally complete these actions.

Needle detector maintenance matters:
The conveyor belt of the needle detector must be thoroughly cleaned every week, and a special cleaning cloth should be used. The surface of the conveyor belt must be cleaned because the product is relatively dirty. The back of the conveyor belt should also be cleaned consciously. During daily use, dirt containing trace amounts of iron may adhere. If such dirt is accumulated, even if there is no needle in the machine, it will react to the dirt on the conveyor belt.
Finally, looking for a good quality needle detector and needle detector, it is recommended that you choose Guangdong Shanan Technology. The company mainly produces and sells various metal detection equipment, foreign object detection equipment, needle detectors, needle detectors, etc. The detection is accurate and well received.
