Description

Technical Field

[0001] The utility model relates to the technical field of single-needle lockstitch sewing machines, in particular to a high-precision single-needle lockstitch sewing machine for fabrics. Background Art

[0002] The flat-bed sewing machine is also called a flat car, generally known as a single-needle flat-bed sewing machine. The flat-bed sewing machine mainly uses a sewing thread to form a stitch on the sewing material, so that one or more layers of sewing materials are interwoven or sewn together. It is usually divided into two uses: thin materials and thick materials. The flat-bed sewing machine can sew fabrics such as cotton, linen, silk, wool, and artificial fibers, and products such as leather, plastic, and paper. Thin materials are generally used for knitting, underwear, shirts, uniforms, etc., and thick materials are generally used for various sportswear, jeans, fashion, coats, shoes and hats, leather, bags, etc. The flat-bed sewing machine is the most basic type of sewing equipment. In sewing, it is the simplest stitch. The stitches are neat and beautiful, the stitches are uniform, flat and firm, the sewing speed is fast, the operation is simple, and the use is simple and easy to understand.

[0003] The Chinese patent document with publication number CN219586344U discloses a height-adjustable single-needle lockstitch sewing machine, in which the traction belt can be retracted and released through a retracting and releasing assembly, so that the traction belt drives the fixed rod to rise and fall, and the fixed rod drives the lifting plate to rise and fall in the guide plate, so that the height of the placement plate can be adjusted. This solution has a simple structure and a novel design, and is convenient for adjusting the height of the lockstitch sewing machine body and the placement plate, which is convenient for users of different heights to use;

[0004] However, during normal processing, the length of the fabric must be judged based on the operator's experience, which inevitably leads to excess scraps of fabric and a lack of precision, which results in waste. In addition, since there is no measuring mechanism, novices generally cannot operate the equipment accurately to sew fabric, and there is a problem of difficulty in getting started.
