Thread feeding auxiliary device used for sewing machine and facilitating thread end searching

Abstract

The invention relates to the technical field of sewing machine thread feeding auxiliary equipment, in particular to a thread feeding auxiliary device used for a sewing machine and facilitating threadend searching. The thread feeding auxiliary device comprises an equipment main body; a fixing frame is fixedly connected to the top surface in the equipment main body; a limiting spring is fixedly connected to the lower surface of the fixing frame; a connecting rod is fixedly connected to the lower surface of the limiting spring; a positioning plate is fixedly connected to the lower surface of theconnecting rod; a rotating wheel is rotatably connected to the lower surface of the positioning plate; and a positioning frame is fixedly connected to the position, located below the rotating wheel,of the bottom surface of the interior of the equipment main body. The rotating wheel is clamped into the limiting plate, and meanwhile, the thread between the rotating wheel and the limiting plate isclamped, so that thread slipping is avoided, and a broken thread end is found conveniently and timely; and plush is treated, a thread outlet is prevented from being blocked, and meanwhile, thread accumulation and knotting are avoided, so that the occurrence rate of short threads of equipment can be well reduced, and therefore the equipment works more smoothly.

Description

technical field [0001] The invention relates to the technical field of thread-entry auxiliary equipment for sewing machines, in particular to a thread-entry auxiliary device for sewing machines that are convenient for finding thread ends. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing materials. The sewing machine can sew cotton, hemp, silk, wool , artificial fiber and other fabrics, the stitches are neat and beautiful, flat and firm, the sewing speed is fast, and the use is easy, and art forms such as hand-push embroidery and computer embroidery are derived from it. [0003] However, the existing sewing equipment cannot handle the plush on the thread well during the process of entering the thread, which may cause blockage and knotting of the thread opening, which may affect the normal operation of the equipment. Moreover, wh...

Problems solved by technology

[0003] However, the existing sewing equipment cannot handle the plush on the thread well during the process of entering the thread, which may cause blockage and knotting of the thread opening, which may affect the normal operation of the equipment. Moreover, when the thread breaks When it is dropped, it is inconvenient to find the broken thread end, thereby delaying time; therefore, those skilled in the art provide a kind of thread-entry auxiliary device that is convenient for the sewing machine to use to find the thread end, to solve the problems raised in the above-mentioned background technology
