The invention discloses a special type pattern machine for sewing in a large area. The special type pattern machine comprises a machine head, a guide rail, a sliding support, a frame, a Y-direction guide rail, a bedplate fixing frame, an X-direction driving motor, an electric cabinet, a digital display and the like. A core part of a control system is a digital signal processor (DSP) master chip, namely a central processing module and a field programmable gate array (FDGA); the control system comprises a controller, a driver, a motor and electromagnets; the controller controls the movement of a servomotor for a spindle and a step motor for a cloth feeding mechanism, and completes other auxiliary functions by means of the electromagnets; in the cloth feeding mechanism, X-direction and Y-direction step motors drive shafts L2 and L1 to make the X and Y displace, the X-direction step motor drives the shaft L2 and a width module through an arc gear, and the Y-direction step motor drives a length module through a gear to brake the shaft L1; and a touch screen technology is adopted, a built-in liquid crystal display panel sets an upper limit and a lower limit in midway limitation, and electronic static discharge (ESD) control is installed. The special type pattern machine has high production efficiency, wide sewing range and diversified sewing patterns.
