What is a needle detector? The English name of needle detector is needle detectors. Alias: needle detector, needle detector, it is a ferromagnetic metal induction instrument, it is a kind of detection instrument in the metal detector category and the textile industry. It is mainly used for the detection of foreign materials on textile ferromagnetic metals. Therefore, the purpose of metal detection instrument development is to detect broken needles in textiles, hence the name: needle detector.
Needle detectors are also called needle detectors, needle detectors, iron detectors, desktop needle detectors, handheld needle detectors, portable needle detectors, toe needle detectors, and conveyer needle detectors. The most commonly used and convenient is a conveying needle detector, which is generally used to detect iron, needles in shoes, clothing, hats, toys, textiles, food, pharmaceutical products, clothing, sports shoes, plush toys, etc. , Nail. Features: This type of needle detection has high sensitivity and good stability. It will automatically alarm when a broken needle is detected, and it will be returned for use on the production line. The goods must be checked by needle detector / needle detector / conveyor needle detector and desktop needle detector before packing. The working principle of the needle tester is: firstly, the upper and lower probes receive and process signals, and then they are sensed by strong magnetic field induction and photoelectric scanning, and then there are strong current integration blocks, sensitivity control integration blocks, signal reception integration blocks, and signal output integration blocks. Complete testing. When the goods passing through the needle testing machine have broken needles or substances containing ferrous metal, the needle testing machine is not allowed to pass. When the ferrous metal is detected, the needle testing machine will automatically alarm and the conveyor belt will go back to put the product. According to the position of the broken needle signal indicator, the inspector can quickly find the broken needle of the product. Otherwise, if no metal is detected, the needle can pass through the channel of the needle detector. According to the regulations that the exported textiles must pass the needle break detection, the products that pass the needle break detection of the needle inspection machine can be exported. Passed products can be packaged for export, otherwise they will be stuck at customs! Therefore, a needle detector must be used for needle detection!
In the 1970s, there was an incident in Japan that caused children to be injured and died from broken needles. Therefore, the Japanese law "Needle Detection Law" explicitly requires all textiles and all wearable items in contact with human skin to be tested for sharp metal foreign objects before entering the retail link. Because the starting point of the needle detection method is caused by broken needles, this method pays special attention to broken needles. Non-ferrous magnetic metal accessories such as copper and aluminum are not included in the detection range of broken needles.
Because the needle detector is a high-sensitivity detection instrument, it has relatively strict requirements on the environment and the maintenance of the machine. Therefore, after a period of use, in order to ensure normal use, you should regularly clean the conveyor belt and other parts that are easily soiled every day. 1, cleaning utensils: find a clean towel, moisten it with water and wring it out until you can't screw it out. 2. Clean the surface of the conveyor belt: Note that the sensitivity of the needle detector should be adjusted to the lowest level before cleaning. If the needle detector has B / C mode, please adjust the needle detector to C mode, so as not to affect the sensitivity too much Cleaning work. Then straighten the towel and press it properly on the surface of the conveyor belt, start the machine, and run the machine for more than five turns (the purpose is to clean the pollutants on the surface of the conveyor belt, the method can be flexibly applied by itself), and then wash the towel clean and wring dry Repeat this step again to wipe the conveyor belt until there is no obvious contamination on the surface of the conveyor belt. 3. Clean the back of the conveyor belt: then wash and dry the towel, pass the towel from the bottom of the machine to the bottom of the conveyor belt, straighten the towel, Pull the towel to the front of the conveyor, hold the towel tightly at both ends, and start the machine to run the machine for several weeks. Because the bottom of the conveyor belt is the dirtiest place, multiple wipes are required. After running for several weeks each time, remove the towel and wash and repeat the above steps. 4. How to judge the cleaning effect: After the above two cleaning steps, adjust the sensitivity of the needle detector conveyor to level 8 or the highest sensitivity, start the machine and let the machine run. At this time, clothes without any metal impurities are put in at this time, and the clothes can pass the needle detector channel smoothly, that is, the conveyor belt is successfully cleaned! Impact: ※ Permanent magnets are used for the needle detection sensor of the magnet's demagnetization needle detector, but after years of use, the magnetic force of the device will gradually decrease. Therefore, the test sample for testing must be placed at a predetermined position for inspection before use.
