Abstract

The invention discloses a thick material sewing machine needle pitch adjusting mechanism with small needle noise and high adjusting precision. The thick material sewing machine needle pitch adjusting mechanism comprises a bracket, a silencing layer is arranged in the inner wall of the bracket, a machine frame is arranged in the bracket, an adjusting mechanism is arranged on one side of the machine frame, and the adjusting mechanism is connected with a driving power supply. A lubricating box is arranged on one side of the interior of the bracket and located above the adjusting mechanism, an oil cavity is formed in the top of the interior of the lubricating box, a conveying pipeline is arranged at the center of the bottom of the oil cavity, the bottom end of the conveying pipeline is connected and communicates with a working groove, a disc is arranged in the working groove, the disc is connected with a driving mechanism, and a plurality of oil containing grooves are evenly formed in the side edge of the disc. The thick material sewing machine needle pitch adjusting mechanism with the small needle noise and high adjusting precision has the beneficial effects that through the driving mechanism, the disc can only rotate by one sixth circle each time, so that each oil containing groove can only move by one step, the lubricating oil can be conveniently discharged, and the situation that the discharging amount of the lubricating oil is not uniform each time is avoided.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to a sewing machine for thick materials, which has a small needle noise adjustment mechanism and high adjustment precision. 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. [0003] 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. [0004] The sewing machines in the prior art use a motor to automatically adjust the stitch length, while satisfying the adjustment of the stitch length, but most of these sewing machines use chain transmission, belt transmission, etc. to drive the stitch length adjustment device, resulting in relatively loud noi...
