Grinding device for sewing machine needle production

Abstract

The invention discloses a grinding device for sewing machine needle production. The grinding device for sewing machine needle production comprises a rotating shaft, a grinding roller, a limiting ring, a thread screwing block, a first fixing mechanism and an inserting groove. When the grinding device for sewing machine needle production is used, firstly, the grinding roller is taken to be arranged on the rotating shaft in a sleeving mode, one side of the grinding roller makes contact with the limiting ring, then the thread screwing block is taken to be screwed at the end of the rotating shaft, meanwhile, the threaded screwing block makes contact with the grinding roller, and the grinding roller is pressed to be fixed to the rotating shaft; then the first fixing mechanism is taken, a sewing machine needle needing to be ground is woven in a placing groove in a fixed bottom plate, then a thread handle is rotated, and drives a movable sleeve to slide in a second sliding groove through a second sliding rod, the movable sleeve drives a pressing top plate to get close to the fixed bottom plate, and finally a pressing groove is pressed at the outer side of the sewing machine needle; and therefore, the sewing machine needle is fixed into the first fixing mechanism, and then an inserting block on the first fixing mechanism is inserted into the inserting groove.

Description

technical field [0001] The invention relates to the field of mechanical production, in particular to a grinding device for sewing machine needle production. 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 material. The sewing machine can sew fabrics such as cotton, fiber crops, silk, wool, and artificial fibers, and products such as leather, plastics, and paper. And it derived art forms such as hand-push embroidery and computer embroidery. According to the purpose of the sewing machine, it can be divided into household sewing machines, industrial sewing machines and service industry sewing machines between the two; according to the driving mode, it can be divided into hand, pedal and electric sewing machines; according to the sewing stitches can be divided into Sewing machine for hand stitch, bartack stitch, single-thread ch...
