The invention provides a buttonholing machine. The buttonholing machine comprises an upper trimming mechanism used for cutting an upper thread, a lower trimming mechanism used for cutting a bobbin thread and a presser foot lifting mechanism used for lifting a presser foot; the upper trimming mechanism comprises an upper trimming driving component and an upper trimming execution component driven bythe upper trimming driving component to act, the lower trimming mechanism comprises a lower trimming driving component and a lower trimming execution component driven by the lower trimming driving component to act, the presser foot lifting mechanism comprises a presser foot lifting driving component and a presser foot lifting execution component driven by the presser foot lifting driving component to act, and the upper trimming driving component, the lower trimming driving component and the presser foot lifting driving component are driven by the same driving motor to act. According to the buttonholing machine, the upper trimming driving mechanism, the lower trimming mechanism and the presser foot lifting mechanism can be simultaneously driven by one driving motor to act, so that the structure and electronic control of the buttonholing machine are greatly simplified and optimized, and then the manufacturing cost of the buttonholing machine can be greatly lowered.
Description
technical field [0001] The invention relates to a garment sewing device, in particular to a buttonhole machine. Background technique [0002] The buttonhole machine is a type of industrial sewing machine, which belongs to a special machine, and is mainly used to process buttonholes in various clothing. With the continuous development of technology, the buttonhole machine is also developing in the direction of semi-automation and full automation, so its functions are becoming more and more perfect. For example, the buttonhole machine can realize functions such as automatic thread trimming, automatic presser foot lifting, and automatic sewing. . For this reason, the upper thread trimming mechanism for cutting the upper thread, the lower thread trimming mechanism for cutting the bottom thread, and the presser foot lifting mechanism for lifting the presser foot are all configured in the buttonhole machine. At present, the upper thread trimming mechanism, the lower thread trimm...
