Description

Technical Field

[0001] This application relates to the field of textile control technology, specifically to integrated control systems, textile machinery, and textile control methods. Background Technology

[0002] A crochet machine is a variant of a narrow-width Raschel warp knitting machine, consisting of a horizontally arranged needle bed and guide bars, and a weft guide bar arranged vertically above the needle bed. Crochet machines are commonly used to produce narrow-width warp-knitted fabrics such as lace and elastic bands. Specifically, the warp yarns fed into the guide bars are first knitted into loops using latch needles or self-closing crochet needles, and then the weft yarns fed into the weft guide bars are clamped in the loops of the ground knitting.

[0003] The existing control system of a crochet machine consists of multiple power distribution components, frequency converters, and switching power supplies, requiring a bulky electrical control cabinet to house these components, with numerous cables connecting them. Therefore, the existing crochet machine control system suffers from problems such as ease of imitation, complex system wiring and debugging, and high cost. Furthermore, placing the frequency converter and other components inside the electrical control cabinet leads to high internal temperatures, necessitating the addition of cooling fans within the capacitor bank. However, adding cooling fans significantly reduces the protection level of the electrical control cabinet, making it unsuitable for harsh operating environments. Summary of the Invention
