Multi-stitch flat type interlocking seam sewing machine

Abstract

The invention relates to the technical field of interlocking seam sewing machines, in particular to a multi-stitch flat type interlocking seam sewing machine which comprises a sewing machine body, a workbench, supporting legs, guiding mechanisms, a protective shell and a controller, wherein the workbench is located on the supporting legs and fixedly connected with the supporting legs, the sewing machine body is fixedly connected to the upper end of the workbench, and arc chamfers are arranged on two opposite edges of the workbench; the guiding mechanisms are located on two sides of the workbench, and each guiding mechanism comprises a fixing plate, a driving roller, a driven roller and a motor; and each fixing plate is fixedly connected to the corresponding side of the workbench. The guide mechanisms drive fabric to move on the workbench and is matched with the sewing machine body to sew the fabric, so that the guide mechanism can move away the sewed fabric, the smoothness of the fabric on the workbench is guaranteed, the situation of sewing interruption caused by fabric wrinkles is prevented, and therefore, the stability and the quality of the multi-stitch flat type interlocking seam sewing machine for sewing and weaving the fabric are improved.

Problems solved by technology

[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 materials; the sewing machine can sew cotton, hemp, silk, wool , artificial fiber and other fabrics and leather, plastic, paper and other products, the stitches are neat and beautiful, smooth and firm, the sewing speed is fast, and the use is easy; and art forms such as hand-push embroidery and computer embroidery are derived from it; due to the lack of existing technology , so that the fabric that has been sewn needs to be pushed away during the fabric sewing process. The process is cumbersome and affects the operation of the staff. The situation of weaving interruption, which also affects the quality of fabric sewing

[0003] There are also some technical solutions about multi-needle flat chain sewing machines in the prior art. For example, a Chinese patent with application number CN201010269955.9 discloses multi-needle flat chain sewing machines. It has a needle that moves up and down, and a thread divider that swings horizontally on the cloth loading surface, and is configured to supply decorative threads to the upper surface of the seam to sew decorative patterns. Among them, there are: fixed thread guides, the fixed The thread guide is fixed on the sewing machine casing and is provided with a first long hole and a second long hole side by side above the thread divider; two hooks are arranged side by side on the thread divider and are connected with the decorative line card This technical solution can easily confirm that the three needles are arranged at a predetermined interval on the cloth surface side; however, this technical solution needs to push the woven fabric away during the fabric sewing process, which is cumbersome and affects the staff. At the same time, it is necessary to maintain the flatness of the fabric being sewn during the sewing process, to prevent the fabric from being folded and causing the interruption of the sewing, which will also affect the quality of the fabric and cause the limitations of the solution.
