5. High frequency switching power supply developed by needle testing machine, strong adaptability;
6. Needle testing machine adopts integrated design, optimize product design, reduce the number of components, by computer to replace the complex electronic components, so that the failure rate is doubled down;
7. Needle testing machine is controlled by computer precisely to prolong the life of the motor;
8. Needle inspection machine accurate counting, qualified, defective, total;
9. Needle testing machine will stop automatically after ten years of unmanned operation;
10. Needle testing machine can set the product testing time;
11. Needle detector with manual and automatic control two options, the operation is more convenient and flexible.

Needle testing machine constitution
1. Detection sensor (probe): it is composed of the upper detection sensor and the lower detection sensor (located below the conveyor belt), forming the height through which the detection items of different specifications can pass, referred to as detection height；
Principle: magnetic sensitive signal, referred to as magnetic cutting line
2. Circuit control system: signal amplification circuit and signal loop alarm system, power protection circuit consists of three parts
Principle: Iron foreign matter can be captured more quickly through signal amplification. When iron foreign matter hits and destroys the normal magnetic cutting line, the magnetic cutting line is distorted and deformed. At this time, the circuit outputs trigger signals to form an alarm loop to achieve the ideal effect of detection and alarm；
3. Electric machine: gear reduction single-phase capacitor rotation motor
Principle: Gear speed ratio rotation, reduce load, prolong life；
4. The conveyor belt, conveyor belt is used will need to test items carried detection sensor for testing tool, the steps of the so adopted anti-static special nylon, knitting woven mesh cloth, the surface adhesion of special rubber, absolute guarantee that the conveyor belt does not contain a little iron and metal components, to ensure the detection sensor without alarm；

 5. Machine frame: the frame made of steel plate, to achieve the role of the bridge of the whole machine, is the primary frame of the multifunctional state structure of the needle machine, so that its performance is more stable, the appearance of electrostatic spraying, both beautiful and can prolong the service life；
6. Wing shell: both play the appearance decoration, the early use of aluminum plate production, relative to iron plate plays a certain signal shielding role, because the aluminum plate shell handmade, suitable for small production of manufacturers or customized non-standard machine, the strength of the manufacturers are using their own die-opening engineering hard plastic shell；
7. Drive shaft: stainless steel tube combined with flat bearing as the rolling structure of the four drive shafts, so that the concentricity of the drive to ensure smooth lubrication, low noise, low heat, prolong the service life；
8. Photoelectric infrared reflector - the working state will emit a beam of invisible infrared, when the detected objects through infrared interception and transmission signal to the recorder, and finally qualified items for counting；
9. Fixed feet: each machine has 4 fixed feet, which can be adjusted smoothly and firmly when installing the machine until the machine does not shake；
10. Control panel: used to control machine operation and sensitivity debugging, display counting and other functions.
