Problems solved by technology

When sewing pieces, the width of the seam allowance is generally determined by experience, and the width of the seam allowance cannot be accurately estimated. As a result, after the pieces are sewn, the width of the seam allowance is inconsistent, which directly affects the appearance quality of the finished garment and reduces the quality of the garment.

Abstract

The invention discloses a sewing machine capable of positioning seams, a seam positioning mechanism and a method. The sewing machine comprises a machine body and a machine head arranged on the machine body, and the machine head is provided with a needle bar used for installing a machine needle; the seam positioning mechanism comprises a mechanism body, a controller, a first laser emitter, a second laser emitter, a drive member, a laser measurement sensor and a width input member; the controller is connected to the first laser emitter, the second laser emitter, the drive member, the laser measurement sensor and the width input member electrically; the first laser emitter is installed on the mechanism body, the second laser emitter is connected to the drive member and is movably arranged on one side of the first emitter, a first laser beam emitted by the first laser emitter is crossed with a reference line, and a second laser beam emitted by the second laser emitter is parallel to the first laser beam. The seam width can be positioned accurately, and the product quality can be improved.

Description

technical field [0001] The invention relates to a sewing device, in particular to a sewing machine capable of positioning seam allowances, a seam allowance positioning mechanism and a method. Background technique [0002] In the process of making clothing or other items, the part that is sewn in is called a seam allowance, and the seam allowance width refers to the distance between the seam line of the cut piece and its edge. When sewing pieces, the width of the seam allowance is generally determined by experience, and the width of the seam allowance cannot be accurately estimated. As a result, after the pieces are sewn, the width of the seam allowance is inconsistent, which directly affects the appearance quality of the finished garment and reduces the grade of the garment. Contents of the invention [0003] Based on this, it is necessary to address the defects of the prior art to provide a sewing machine capable of positioning seam allowances, a seam allowance positionin...
