Device for detecting performances of electromagnetic valves and weft stop pins

Abstract

The invention relates to a device for detecting the performance of electromagnetic valves and weft stop pins. The device is used for maintaining the weaving machine of textile machinery. The air outgoing side of an air source is connected with a digital pressure gauge; the air outgoing side of the air source is communicated with the air inlets of valves; the air outlets of the valves are connectedwith electromagnetic valves; the air outlets of the electromagnetic valves are connected with a sensing circuit I through air pressure sensors; the output end of a driving circuit is connected with the electromagnetic valves or the weft stop pins; the driving circuit drives the electromagnetic valves or the weft stop pins to work; distances between the needles of the weft stop pins and proximityswitches are 1-3 mm; the proximity switches are connected with a sensing circuit II; the driving circuit is connected with a control circuit; the sensing circuit is connected with the control circuit;the control circuit is connected with a touch display screen; the control circuit is connected with a switching power source; and the digital pressure gauge is connected with the control circuit I. With the device of the invention adopted, the on-site working environment of the electromagnetic valves and the weft stop pins can be simulated so as to accurately detect the technical performance of the electromagnetic valves and the weft stop pins; and the defect that manual repeated assembling and disassembling is adopted to detect whether the performance of the electromagnetic valves and the weft stop pins is intact or not is overcome, and detection efficiency and reliability are greatly improved.

Description

technical field [0001] The invention relates to the technical field of textile machinery and loom maintenance, in particular to a device for detecting the performance of an electromagnetic valve and a weft stop pin. Background technique [0002] In textile machinery, solenoid valves are electromagnetically controlled industrial components that are used in production control systems to adjust the direction, flow, speed and other functions of media. The solenoid valve can cooperate with different circuits to realize the expected control, and the accuracy and flexibility of the control can be reliably guaranteed. The solenoid valve can also control the opening and closing of the fluid in the air flow pipeline. Different equipment and different environments have different requirements for the opening time, air pressure change, and cut-off time of the solenoid valve. For example, on an air-jet loom, when the performance of the solenoid valve is aging, the movement of the airflow...

AI Technical Summary

Problems solved by technology

For example, on an air-jet loom, when the performance of the solenoid valve is aging, the movement of the airflow cannot be controlled according to the normal requirements, resulting in frequent weft stoppages or defective fabrics, requiring maintenance personnel to try to replace the solenoid valves one by one, which not only causes a lot of waste of manpower , which increases the production cost, and also greatly affects the product quality, normal operation and production efficiency of the air-jet loom

When the performance of the stop weft pin is aging, if it cannot be opened or returned within a certain period of time, it will cause the air-jet loom to stop illegally, requiring maintenance personnel to use solenoid valves to try to replace them one by one, which not only causes a lot of waste of manpower, but also increases production costs. Thus affecting the opening efficiency of the air-jet loom
