Description

technical field [0001] The invention relates to a control system of a textile machine, in particular to an improved control system of a rapier loom. Background technique [0002] my country's shuttleless looms have been developed for nearly 20 years. Various types of looms have reached the current stage of independent technology research and development through technology introduction, learning and absorption. Among them, rapier looms develop particularly rapidly and are most widely used because of their advantages of high efficiency, strong variety adaptability and high automation. Towel rapier looms have also replaced old weaving equipment as the main equipment for towel weaving. The new rapier towel loom replaces the mechanical transmission function with advanced electronic technology to realize the controllability of multiple actuators. The focus of its development is the further improvement of stability, reliability and anti-interference ability. The existing terry r...
