A feeding wheel 10 used in conjunction with the feeding tray 2 is installed at the other end of the mounting seat 7, and a gear set is provided between the feeding wheel 10 and the driving gear 8, so that the rotation of the feeding wheel 10 is controlled by the driving motor 5.

[0021] The utility model makes the layout of the transmission component more reasonable through the design of the mounting seat, and enables the curved arm 3 to be installed on the side away from the sewing component through the cooperation of multiple sets of gears, which greatly increases the operating space and facilitates the workers to perform sewing operations. Compared with the existing technology, it does not cause obstruction to the line of sight and the feeding operation of the hands, and has a good field of vision, which is conducive to reducing the work intensity of the workers and improving work efficiency.
