The needle detector is mainly used to detect broken needles and metal debris in sewing products such as clothing and toys. In order to improve the detection accuracy, the needle detector must be calibrated every time it is used. The calibration of the needle detector requires What factors should be paid attention to?
Clothing factory inspection
The calibration of the needle detector should mainly pay attention to the following points:
① The working power of the needle detector is normal: the power indicator light is on after turning on the machine, the working indicator light is off when the needle detector is in standby, and the working indicator light is on when it is working;
②Conveyor belt transportation is normal: when the needle detector is started, the conveyor belt rotates normally, without deviation, and there is no abnormal sound;
③Sensitivity of the needle detector: Put the standard test piece and the test piece of the needle detector into the induction frame, cut in and move at a speed of 25m/min to test respectively. If two pieces of 1.0Fe (needle detector channel height 15CM) test pieces pass through the induction frame, and the needle detector emits a buzzing sound, the sensitivity of the needle detector is qualified. If one of the test pieces passes through the induction frame, if the needle detector cannot make a correct response, the needle detector is unqualified, and it is necessary to find out the reason, identify and eliminate the fault.
(The most common faults of the needle detector are: 1. The conveyor belt is dusty or mixed with iron filings. The solution is to wipe it with a clean wet wool. Note that the back of the conveyor belt is the place that needs to be wiped most. The wiping will not work even if it is clean. Second, the sensitivity is reduced, the solution: increase the sensitivity. For specific adjustment methods, refer to the needle detector manual)
④ When the calibration result meets the calibration requirements, the needle detector is qualified and the permit is pasted.
⑤ Needle detectors should be calibrated regularly, and the calibration period is usually determined according to the quality of the needle detector and the control requirements for product needle detection. Generally, the calibration period is three months.
