Description

Technical Field

[0001] This utility model relates to the field of flat knitting machine technology, specifically to a knitting flat knitting machine thread feeding mechanism. Background Technology

[0002] A flat knitting machine is a specialized machine for manufacturing knitted fabrics. It typically consists of a needle bed, needle bar, shuttle, feeding system, drive unit, and control system. Through computer programs or manual adjustments, it controls needle insertion, parallel or staggered arrangement, loop formation, and knitting density. Its core principle is to continuously transform yarn into an elastic and structurally stable fabric through the up-and-down movement of needles, the transfer of yarn on the shuttle or warp, and the simultaneous winding and interlacing of multiple yarns. Currently, during operation, flat knitting machines require yarn loading. Due to the elasticity of the yarn, it is prone to slack during loading. Without proper handling, this can easily lead to yarn tangling, knotting, or stagnation. This necessitates assistance from technical personnel, increasing their workload and impacting the overall efficiency and effectiveness of the flat knitting machine.

[0003] Therefore, it is necessary to develop a new thread feeding mechanism for flat knitting machines. Utility Model Content
