Technical Field

[0001] The utility model relates to the technical field of lockstitch sewing machines, in particular to a lockstitch sewing machine with an auxiliary feeding function for clothing design. Background Art

[0002] The flat-sewing machine mainly uses a sewing thread to form a seam 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-sewing machine can sew fabrics such as cotton, linen, silk, wool, and synthetic fibers, and products such as leather, plastic, and paper. Thin materials are generally used for knitwear, underwear, shirts, uniforms, etc., and thick materials are generally used for various sportswear, jeans, fashion, coats, shoes and hats, leather, bags, etc.

[0003] According to the description of a flat sewing machine with auxiliary feeding function for clothing design disclosed on the patent website (authorization announcement number: CN 219260412 U), "The utility model discloses a flat sewing machine with auxiliary feeding function for clothing design, which belongs to the technical field of flat sewing machines, including a sewing platform and a driving motor, a sewing machine head is fixedly connected to the top of the sewing platform, a driving shaft is connected to the output end of the driving motor, and a transmission assembly is connected to the other end of the driving shaft. The transmission assembly is connected to two rotating shafts, and a fixed plate is arranged above the rotating shaft. An infrared sensor is connected to the top of the fixed plate. The utility model can feed and send the fabric away at the same time after sewing by setting a feeding conveyor belt and a feeding conveyor belt, thereby ensuring the timeliness of feeding, avoiding the accumulation of fabric on the side after sewing, and improving the efficiency of the entire sewing process. At the same time, the setting of the angle adjustment disk and the servo motor allows workers to quickly determine the angle of the stitching line, avoiding workers spending time looking for angles when sewing bevel edges, and improving the speed of fabric sewing."
