Air Jet Weft Insertion Solenoid Valve Detector

Abstract

The invention relates to an air jet weft insertion electromagnetic valve detector which is designed for weft insertion electromagnetic valve detection of an air jet loom, so that weft insertion electromagnetic valve receives reliable and scientific parameter detection before being used on the loom, and the phenomenon that the electromagnetic valve with good quality is selected to work on the loom is guaranteed. According to the air jet weft insertion electromagnetic valve detector, a complete closed system is composed of an input unit, an output unit, a control unit, an actuation unit, a feedback unit and the like, so that the functions of automation and intelligence are guaranteed. Compressed air passes through the detector when the detector works. The air with certain pressure is received by a piezoelectric sensor after passing through the electromagnetic valve and relevant information is fed back to a micro-control unit and compared with set parameter values. After the quality of the electromagnetic valve is judged, a result is displayed through a liquid crystal screen, whether the electromagnetic valve is randomly opened and closed, whether some air does not pass through the valve and whether air is leaked are confirmed, and therefore the quality of the electromagnetic valve is judged.

Description

1. Technical field [0001] The invention relates to an air-jet weft insertion electromagnetic valve detector, which is a professional electromagnetic valve intelligent detection device, and is mainly applicable to the detection of the performance parameters of the weft insertion electromagnetic valve used on the air-jet loom and the identification of its quality. 2. Background technology [0002] Since the use of air-jet looms for more than 30 years in the early 1980s, there is no effective detection method for the weft insertion solenoid valve used on air-jet looms. The ventilation test was carried out on the air-jet loom. Practice has proved that these methods cannot effectively identify the quality of the solenoid valve and cannot guarantee the normal use of the solenoid valve on the machine. The detection technology of the electromagnetic valve is still in the research aspect, and there is no mature product on the market at present, especially the detection of the weft in...

AI Technical Summary

Problems solved by technology

[0003] The performance of the weft insertion solenoid valve used on the air-jet loom will decrease with the increase of use time, which will cause abnormal weft insertion of the loom. When replacing it, it is necessary to determine: which solenoid valve on the loom has degraded performance; which solenoid valve to be replaced Can the solenoid valve work normally?

[0004] For textile mills, the previous replacement of the weft insertion solenoid valve on the loom was carried out tentatively. If the replaced solenoid valve cannot be used normally, it has to be replaced and tried again. This will cause a long downtime, affect the output, and affect the staff. emotion, an air-jet loom often needs to replace the solenoid valve several times in a row before it can operate normally.

[0005] For the production or maintenance of solenoid valves, whether the performance parameters and quality of newly produced or just repaired solenoid valves are reliable also needs to be effectively tested, otherwise it is difficult to ensure normal use
