Handling of common faults of HASHIMA Hashima needle detector
|
|
In the daily use of the needle detector, there will be more or less abnormal situations; the following analysis of some common faults of the HASHIMA Hashima needle detector, so that the maintenance personnel can judge on site.
1. Transmission part
A. Abnormal sound of friction between the transmission belt and the transmission shaft; the solution is to use baby powder to sprinkle the inside of the belt; start the belt to rotate for one or two minutes, and it can be solved.
B. Abnormal noise of the parallel roller (supporting the shaft under the belt) during operation; the solution is to replace the top block of the roller shaft or tighten the fixing bolts, and apply lubricating oil in the top block.
C. The speed of the belt is lost, and the solution is to check whether the motor V-belt and motor pulley tightening screws are loose.
D. The belt deviation is serious; the solution is to replace the driving and driven rollers for older models; the reason is that the rollers wear out during long-term use, and the parallelism of the rollers cannot meet the requirements.
E. The belt retreat is not in place or does not retreat; the belt retreat knob is slightly larger, and check whether the relay is damaged.
F. The belt speed is slow and uncontrolled; it may be caused by damage to the motor communication circuit board.
Second, the detection part
A. The machine starts to alarm immediately; the solution is to set the machine to test mode to see if it alarms; if there is no alarm, check the photoelectric switch; observe whether the light position of the photoelectric switch is displayed normally.
B. Occasionally alarm after the machine starts; solve the countermeasures, observe whether the interference indication has regular high jump; if there is regularity, it means that the belt is dirty, try to wipe it with alcohol; see if it improves, especially if the belt is damaged.
C. When the machine is in the production mode, the irregular interference indicates the high jump, and countermeasures; observe whether the machine is moving or rotating within 2M of electrical parts, such as fans, etc.; observe whether there is a large machine operating downstairs. The needle detector is sensitive to iron items, especially moving iron.
D. When there is no external interference, the interference indicates high jump; the countermeasure may be that the machine is magnetized; it is necessary to try to degauss the machine roller.
E. The detection results of the single-head needle detector are different when the article changes direction; the solution is that the needle detector uses a magnetic cross section to detect, because the iron content of the article is different in the cross section when it passes, the detection results are different ; Therefore, it is recommended to use a double-headed needle detector for testing under strict conditions.
F. The thin clothing cannot be detected; the solution is to change the detection mode to the test mode;
