Abstract

The invention discloses a sewing machine and a sewing method. The sewing machine comprises a workbench, a feeding device, a material clamping device, a location device and a stitching device, and the feeding device, the material clamping device and the stitching device are arranged on the workbench. The feeding device is provided with a fixing base, a cloth feeding roller, a first driving element and a second driving element, a cloth feeding roller shaft is connected to the fixing base, the first driving element is connected to the fixing base, and the second driving element is connected to the cloth feeding roller for driving the cloth feeding roller to rotate. The material clamping device is provided with two material clamping plates, wherein the two material clamping plates are arranged in an overlapped mode, a cutting piece is placed between the two material clamping plates which are arranged in the overlapped mode, and the two material clamping plates are provided with a stitching channel. A stitching needle of the stitching device is oriented to the stitching channel. The location device is provided with a detecting element and a reflection element, the reflection element is located on the material clamping plate arranged on the uppermost layer of the material clamping device, and the detecting element inducts the reflection elements and gives out a needle pitch changing signal. By means of the sewing machine, cutting pieces of different needle pitches can be stitched at designated positions automatically.

Description

technical field [0001] The invention relates to the field of garment making, in particular to a lockstitch sewing machine and a lockstitch sewing method. Background technique [0002] In recent years, the technical requirements of the garment industry have become higher and higher, and the style changes have also shown a trend of rapid, multiple and complicated development. Faced with the need to sew two or more different stitch lengths on the same sewing thread track, there is not yet a very perfect machine on the market that can achieve this function. If it is manually operated, it needs to be sewn stitch by stitch according to the designated position with hand needles, which is very serious to the waste of manpower and material resources. Contents of the invention [0003] Based on this, it is necessary to provide a lockstitch sewing machine capable of automatically sewing pieces with different stitch lengths at a designated position. [0004] A lockstitch sewing mach...
