Problems solved by technology
[0006] However, although this design of two sets of template sewing machines corresponding to the mop mechanism can ensure the reliability of the template feeding, the additional two sets of mop mechanisms will cause the structure of the sewing machine to be complicated, and the manufacturing cost will also increase significantly. Therefore, in Under the premise of not complicating the mechanism of the sewing machine, how to increase the feeding force of the template is actually the focus of the improvement of the current template sewing machine.

The invention provides a material-drawing mechanism of an electric template sewing machine. A roller support is installed on a presser foot rod of the sewing machine, so that the roller support can generate pushing down force. A material-drawing roller of the roller support, corresponding to the position of feeding teeth, is pivoted above a needle plate, so that the material-drawing roller and the feeding teeth are longitudinally arranged at the upper and lower sides of a template in parallel. A driving device is connected to the material-drawing roller and drives the material-drawing roller to cooperate with the feeding teeth for synchronously movement, and the template generates a displacement action. The material-drawing mechanism enhances the feeding force which drives the template to move through perpendicular correspondence between the feeding teeth and the material-drawing roller. Furthermore the material-drawing mechanism also has the pushing-down effect instead of the traditional presser foot structure, and effectively simplifies the whole member of the template sewing machine.
Description
technical field [0001] The invention relates to a sewing machine which uses a template to hold and sew materials, in particular to an electronic template sewing machine which combines a material pulling mechanism and a pressing mechanism to simplify components. Background technique [0002] Generally, template sewing machines are mainly equipped with a mop wheel on the sewing machine to press on the template, and when the mop wheel rotates, the displacement of the template is driven by friction force. Please refer to figure 1 As shown, the traditional template sewing machine mainly installs a stepping motor 11 outside the casing 10, and a pressing rod 12 is pierced at the front end of the casing 10, and a presser foot 13 and a tugboat mounting bracket are provided at the lower end of the pressing rod 12. 14. The tugboat mounting bracket 14 extends outward and is connected to a mop wheel 16 through a tugwheel shaft 15, and the tugwheel shaft 15 is connected to the stepping mo...
