Thread winding device for sewing machine

Abstract

The invention discloses a thread winding device for a sewing machine. The thread winding device comprises a base plate, wherein a first support plate and a second support plate are fixedly connected to the upper surface of the base plate, the first support plate is located on the left side of the second support plate, a first groove is formed in the second support plate, a bearing is fixedly connected in the first groove, a first connecting shaft is rotatably connected to the inner wall of the bearing, a second connecting shaft is rotatably connected to the inner wall of the first support plate, a driving motor is rotatably connected to one end of the second connecting shaft, bearing sleeves are rotatably connected to the outer walls of the first connecting shaft and the second connectingshaft, support rods are fixedly connected to the lower surfaces o the two bearing sleeves, and connecting rods are arranged at one ends, opposite to each other, of the first connecting shaft and the second connecting shaft. The thread winding device is simple in design and convenient to operate, the winding efficiency can be improved, and the position of a connecting rod can be adjusted accordingto different winding wheels.

Description

technical field [0001] The invention relates to the technical field of winding devices, in particular to a winding device for sewing machines. 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 , man-made fibers and other fabrics and leather, plastic, paper and other products, the stitches are neat and beautiful, flat and firm, fast sewing speed and easy to use, and derived from it Art forms such as hand-push embroidery and computer embroidery.
