Yarn storage and feeding driving device and method, horizontal loom, equipment and storage medium

Abstract

The invention provides a yarn storage and feeding driving device and method, a horizontal loom, equipment and a storage medium. The yarn storage and feeding driving device comprises a control module,a switching power supply module, a first power inverter module and a second power inverter module; the control module is electrically connected with the first power inverter module and the second power inverter module separately; the switching power supply module is electrically connected with the first power inverter module and the second power inverter module separately, and direct current output by the switching power supply module is converted into yarn feeding alternating current by the first power inverter module and converted into yarn storage alternating current by the second power inverter module. The control module is adopted for controlling opening and closing of the first power inverter module and / or the second power inverter module, so that turning on and turning off of a yarnfeeding motor and / or a yarn storage motor are controlled; the stability of the direct current obtained after conversion by the switching power supply module is high, so that the stability of the yarnfeeding motor and yarn storage motor is high, the rejection rate is decreased, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of knitting, in particular to a yarn storage and feeding driving device and method, a flat loom, equipment and a storage medium. Background technique [0002] A flat knitting machine is a machine that can weave materials such as wool, fibers, and yarns into knitted products such as sweaters, scarves, and hats. Flat looms usually include a yarn storage mechanism and a yarn feeding mechanism, which store and feed yarn for the machine head. At present, the yarn storage mechanism and the yarn feeding mechanism are driven by two single-phase AC motors with different voltage levels. The driving voltage of the yarn storage mechanism is usually AC42V, and the driving voltage of the yarn feeding mechanism is usually AC110V. [0003] The voltage source of the yarn storage and feeding drive device is generally converted from the mains power through a power frequency transformer. refer to figure 1 , the existing yarn...
