Maintenance Knowledge Of Needle Detector

- Nov 30, 2017-

Because the needle detector is a kind of high sensitivity detection instrument, it has stricter requirements on the environment and the maintenance of the device. Therefore, in the use of a period of time, to ensure that the normal use, should be done daily cleaning conveyor belts and other easily defaced parts.


  1. Cleaning equipment: Find a clean towel, wet the water and then wring dry until you can not wring out.

2. Conveyor belt Surface Cleaning: note, before cleaning should be the first detection needle sensitivity adjustment to the lowest level, such as the needle detector has/mode, please adjust the needle detector to C mode, so as not to affect the high sensitivity of the next cleaning work. Then straighten the towel and tighten it properly on the conveyor belt surface, actuator, so that the device operates more than five laps (the purpose is to clean the surface of the conveyor belt pollution, the method can be flexible application), and then wash the towel to dry, repeat this step to wipe the conveyor belt, until the conveyor belt surface is not obvious pollutants;

3. The back of the conveyor belt cleaning: Then wash the towel to dry, from the lower part of the device will towel through the bottom of the conveyor belt, pull straight towel, and the towel to the front of the conveyor, grasp the towel at both ends, the actuator device operation for several weeks. Because the bottom of the conveyor belt is the dirtiest place, it needs to be wiped many times. After a few weeks of operation, wash out the towel and repeat the steps

4. How to judge the cleaning effect: the needle detector conveyor belt after the two cleaning steps, adjust the sensitivity to level 8 or the highest sensitivity, actuator, let the device operation, such as the smooth operation of the device and the probe metal position display lamp is not lit, at this time to put no metal impurities of clothing, clothing can successfully pass the needle detector channel, The conveyor belt is clean and successful.
