The invention provides a thread-taking rod structure of a sewing machine. In the sewing process, the thread feeding amount and the tension force of the surface line are kept stable when the thread-taking rod runs to different positions, so as to stabilize the stitch in the sewing process of the clothes, better ensure the sewing effect and the sewing quality of the clothes, and the thread-taking rod body of the sewing machine wrapped with the thread-taking rod, and the sewing machine. A thread crossing hole is arranged on the thread picking rod body of the machine, and the threaded hole is a long slot hole. Because the thread-piercing holes on the thread-taking rod body of the sewing machine are long groove-shaped thread-piercing holes, when the thread-taking rod of the sewing machine runs to the lower end, the amount of thread supply becomes larger, which ensures the demand for the amount of thread-passing in the thread-taking mechanism. When the thread-taking rod of the sewing machine runs to the upper end, the surplus line quantity is quickly recovered, and the line quantity matching with the amount of thread is better provided. The crossing resistance of the hooking mechanism is small, and the feeding quantity and the tension of the surface line are stable when the pick-up rod runs to different positions, so that the tension of the sewing line is stable and the stitch is stable in the sewing process.
【技术实现步骤摘要】
一种缝纫机挑线杆结构
本专利技术涉及缝纫设备部件的
,特别涉及一种缝纫机挑线杆结构。
技术介绍
在衣物的缝制过程中,机针带动缝线扎入待缝制品中,勾线机构勾住面线后,勾线机构将面线释放,面线释放后通过挑线杆将面线收紧,与底线交织形成线迹,完成物品的缝制,由于挑线杆的运动轨迹固定,在挑线杆收紧面线的过程中,面线在不同位置时对面线的拉紧力不同,在缝制过程中缝线的张力会发生变化,造成了衣物的缝制中线迹不稳定,从而影响了衣物的缝制效果和缝制质量。
技术实现思路
针对现有技术之不足,本专利技术提供一种缝纫机挑线杆结构,在缝制过程中,挑线杆运行到不同位置时面线的送线量和面线的拉力保持稳定,从而使得衣物的缝制中线迹稳定,较好地保证了衣物的缝制效果和缝制质量。其技术方案是这样的:一种缝纫机挑线杆结构,其包缝纫机挑线杆体,所述缝纫机挑线杆体上设置穿线孔,穿线孔为长槽孔。穿线孔两端为圆弧状;所述穿线孔为椭圆形长槽孔。本专利技术采用上述方案,由于缝纫机挑线杆体上的穿线孔为长槽形穿线孔,当缝纫机挑线杆运行到下端时,供线量变大,保证了勾线机构过线量的需求,当缝纫机挑线杆运行到上端过程中,多 ...
