The invention discloses a curve sewing device based on a flat sewing machine. The device comprises a supporting plate, a circular guide block, a shift fork, a moving drive component, a friction plateand a rotation drive component. The rotation drive component includes a first driven gear, a first driving gear and a first power part, the first driven gear is connected to the bottom of the supporting plate, the friction plate is coaxially connected to the bottom of the first driven gear, the circular guide block is located above the supporting plate and is connected to the first driven gear through a vertical bar, through holes for allowing a needle to penetrate through are formed in the supporting plate, the first driven gear and the friction plate, and the friction plate and the needle are coaxially arranged. As the shift fork drives the friction plate to move up and down and a gear transmission mechanism drives the friction plate to rotate, the device not only can achieve the curve sewing function of the sewing machine, but also has a simple structure. Besides, the friction plate is pressed on a fabric to prevent the fabric from wrinkling during adjustment. In addition, the machine needle is used as the center of rotation, which can reduce the influence on stitch quality due to the adjustment of the fabric position.
Description
technical field [0001] The invention relates to the technical field of sewing machines, in particular to a curved sewing device based on a lockstitch sewing machine. Background technique [0002] The stitches of the sewing machine are divided into two types: straight line and curved line. Cloth is usually stitched together through these two types of stitches. Compared with straight line sewing, curved line sewing has higher requirements and is more difficult. [0003] At present, the template machine is mainly used to realize the curve sewing, but its structure is complicated, the price is expensive, and the disassembly and assembly of the fabric is inconvenient. In addition, the auxiliary curve sewing equipment of the existing locket sewing machine has complex structure and high cost, and is not suitable for large-scale production and popularization. [0004] Therefore, how to provide a curved sewing device based on a lockstitch sewing machine so as to reduce the cost of t...
