The working principle of the needle detector and the performance characteristics of the needle detector

The working principle of the needle detector : When the manufacturer produces clothing, sports shoes, plush toys, etc., the product must pass the needle detection of the needle detector before packaging. Firstly, the upper and lower probes receive and process signals, and are detected by strong magnetic field induction and photoelectric detector scanning, and then have a strong electric integrated block, a sensitivity control integrated block, a signal receiving integrated block and a signal output integrated block to complete the detecting work. When the product passing through the needle detector has broken needles or substances such as iron metal, the needle detector is not allowed to pass. When the iron-containing metal is detected, the needle detector will automatically alarm and the conveyor belt will be reversed to discharge the goods. The original position; from the position of the inspector according to the broken needle signal indicator, can quickly find the location of the broken needle, and if the metal is not detected, it can pass through the needle detector channel. According to the regulations for the detection of broken needles in exporting textiles, the products that have passed the needle-detection inspection by needle detectors can be exported.

Needle detector performance characteristics:

1) Lightweight structure, convenient movement and simple operation.

2) Turn on the power, no need to shake the start switch after the machine is turned on.

3) Adopt the most advanced microcomputer sensitivity digital display, ten levels adjustable.

4) Anti-interference design, breaking the interference of environmental influences (electric fans, mobile phones, sewing machines, etc.).

5) It has two kinds of detection functions: thin material and thick material (ie, type B and type C). Rewind / no rewind function

6) Effective good product count (non-good products are not counted)

7) Accurately display the broken needle position and find the needle break.

8) Automatic alarm and automatic return function when metal is detected;

9) Equipped with a conveyor belt deviation maintaining device to prevent the deviation of the conveyor belt.
