What is a needle detector?

Simply speaking, when manufacturers produce clothes, sports shoes, plush toys and other goods, the goods must pass the needle detection of the needle detector before packaging. The working principle of the needle detector is: Firstly, the upper and lower probes receive and process signals, and are induced by strong magnetic field induction and scanning by the photoelectric instrument, and then there are strong electric integrated blocks, sensitivity control integrated blocks, signal receiving integrated blocks and signal output integrated blocks. Complete testing.

When the goods passing through the needle detector have broken needles or contain ferrous metal or the like, the needle detector is not allowed to pass. The needle detector automatically alarms when the ferrous metal is detected, and the conveyor belt is reversed to release the goods. The original position; From and let the inspector according to the location of the needle signal indicator light, can quickly find the location of the goods broken needle, conversely, if no metal goods can be detected through the needle detector channel. In accordance with the provisions for the detection of broken needles in accordance with the export of textiles, products that pass the needle detector needle detection can be exported.

Qualified products can be packaged for export, or they will be carded at the customs.

Needle detector performance characteristics:

1. The newly developed high-integrated chip ensures high performance and high reliability;

2. High sensitivity, high anti-interference ability;

3. Adopt digital signal processing (DSP) from data acquisition to motor control, highly intelligent;

4. Easy to use, automatic data processing and saving, each time you turn on the machine can keep the setting of shutdown;

5. Self-developed high-frequency switching power supply, suitable for strong capabilities;

6. Adopt integrated design, optimize product design, reduce the number of components, and replace complex electronic components with computers, so that the failure rate is reduced exponentially;

7. Accurately control the timing of the motor by the computer to extend the life of the motor;

8. Accurate counting, qualified, defective, total;

9. Automatically shut down after nobody has operated;

10. Set the machine's product inspection time.

11. The needle detector has two options for manual and automatic control. The operation is more convenient and flexible.
