Special type pattern machine for sewing in large area

Abstract

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.

Description

Technical field: [0001] The invention relates to a sewing machine, in particular to a large-area sewing special pattern machine, which has the function of large-area sewing. Background technique: [0002] In recent years, the driving parts of the prior art pattern machine are driven to the V-belt pulley of the upper shaft through the V-belt pulley of the motor, and then transmitted to the synchronous pulley of the lower shaft through the synchronous pulley of the upper shaft. The V-belt operates for a long time, and it is easy to generate heat, deform, elongate, slip, and make a lot of noise, and the computer control system of the special pattern machine in the prior art is designed and applied according to some specific computer pattern machine models. Therefore, the computer pattern machine It is difficult for the control system to adapt to the control requirements of all the changing mechanical structures of the whole machine. Meanwhile, the sewing range of the prior art ...

Problems solved by technology

The V-belt operates for a long time, and it is easy to generate heat, deform, elongate, slip, and make a lot of noise, and the computer control system of the special pattern machine in the prior art is designed and applied according to some specific computer pattern machine models. Therefore, the computer pattern machine It is difficult for the control system to adapt to all the changing mechanical structure control requirements of the whole machine. At the same time, the sewing range of the existing pattern machine is small, and the sewing pattern is relatively single.
