Abstract

A multi-speed electronic warp let-off system of an improved structure comprises a warp knitting machine body structure, an industrial personal computer, a servo control board and a plurality of servo driving mechanisms for controlling a warp beam of a warp knitting machine to rotate.The servo control board comprises an ARM microcontroller, a DSP and a data storage.The output end of the industrial personal computer is connected to the ARM microcontroller and the data storage through optical fibers respectively.The output end of the ARM microcontroller is connected with the data storage and the DSP respectively.According to the multi-speed electronic warp let-off system, the optical fibers are arranged as media for data connection and transmission of the industrial personal computer, the servo control board and the servo driving mechanisms, the control requirement for real-time high-speed data transmission in the working environment of strong electromagnetic interference and large data throughput can be met, it is ensured that target position instructions for the servo control board and the servo driving mechanisms can be updated in real time during operation of the industrial personal computer, the communication mode is low in production cost, and the communication cost is greatly saved.

Description

technical field [0001] The invention relates to the field of warp knitting machinery, in particular to a structurally improved multi-speed electronic let-off system. Background technique [0002] The warp let-off system is a system that unwinds the warp yarn from the warp beam and sends it into the loop forming mechanism according to a certain let-off amount. It is one of the most important components in knitting machinery (warp knitting machine, weft knitting machine), and directly affects the quality and pattern varieties of warp knitting products. [0003] For now, domestic warp knitting enterprises have a large number of imported warp knitting machines in the late 1990s, most of which use FAG mechanical let-off system, or the original single-speed EBA electronic let-off system cannot solve the problem of product diversification, and has already The aging failure rate is high, and upgrading is urgently needed. Therefore, there is an urgent need to independently develop ...
