Description

Technical Field

[0001] This utility model relates to the field of drawstring and threading technology in clothing, and in particular to a drawstring and threading device for trousers in clothing processing. Background Technology

[0002] Garment processing is the process of turning fabrics and accessories into garments through design and pattern making, fabric pretreatment (fabric inspection, shrinkage, etc.), cutting, sewing, accessory assembly (such as zippers, buttons, drawstrings), ironing and shaping, quality inspection and packaging. The core is to transform raw materials into finished garments that meet design requirements.

[0003] Drawstring threading equipment for trousers is a specialized device used in garment processing to thread drawstrings into the drawstring channels of trouser waistbands, cuffs, and other areas. Its function is to replace manual threading, improving efficiency and ensuring threading quality. The main types include manual threaders (simple in structure, consisting of a threading needle and handle, suitable for small-batch production) and automatic threaders (integrated motor drive system, with functions for feeding, threading, and cutting drawstrings, automatically completing drawstring feeding, threading through the drawstring channel, and cutting to a set length, suitable for mass production). The working principle involves guiding the drawstring into the garment's drawstring channel through a guiding mechanism (such as a threading needle or flexible guide tube). Automatic models also use sensors to locate the garment's position, ensuring accurate threading.

[0004] Manual rope threading is inefficient, cumbersome, and time-consuming, especially in mass production or high-intensity work environments. In contrast, guide mechanism rope threading is designed to improve efficiency and reliability through stable rope output, theoretically reducing manual intervention and operational difficulty. However, in practical applications, this mechanism often faces problems such as rope twisting and line jamming, leading to instability in the threading process and even affecting the overall performance and productivity of the equipment. Therefore, optimizing the structural design and material selection of the guide mechanism while ensuring stable rope output is key to improving rope threading effectiveness and practicality.
