Abstract

The invention relates to an alternating current servomotor control circuit for an electronic planet selvage device. In the prior art, a motor difficultly rotates at a high speed in the control process. The control circuit comprises a master control chip STC89C58RD+, a key input circuit, a nixie tube status display circuit, an external release button and sensor signal input circuit, a selvage control status indicator lamp and alarm output circuit, a spindle encoder signal receiving circuit and a system power circuit, wherein the master control chip directly acquires spindle encoder signals through the spindle encoder signal receiving circuit; the external release button and sensor signal input circuit adopts optical coupling isolation; and alternating current input into the system power circuit is subjected to bridge rectification and is subjected to voltage stabilization by a three-terminal voltage stabilizing module and a switch integration voltage stabilizing module. The circuit hasa simple structure, man-machine communication is convenient, the electronic planet selvage device is operated and controlled flexibly, and the electronic planet selvage device is accurately synchronous with a spindle when the spindle rotates at a high speed.

Description

technical field [0001] The invention belongs to the technical field of motor control, in particular to the technical field of motor control of textile machinery, and relates to an AC servo motor control circuit for an electronic planetary hemming device on an air-jet loom. Background technique [0002] At present, the main application of known air-jet flanging devices is mechanical. Because the mechanical rotation chain of the mechanical leash device is too long, the cumulative error of installation and processing accuracy is large, and the failure rate is high in high-speed looms, which affects the operating rate of the loom; due to structural reasons, the width of the leash device The adjustment of the width and comprehensive leveling parameters is cumbersome; the transmission gear meshing with the levitation device is an open structure, which is not conducive to lubrication and affects the high-speed performance of the system, and is easy to enter sundries and cause damag...
