Computer sewing machine is an electromechanical integration sewing machine based on the development of electronic technology and computer control technology.
The quality of sewing has been improved, and the work efficiency and automation degree have been greatly improved. The material basis and technical conditions have been prepared for the garment enterprises to implement the CIMS system.
Computer sewing machine
This is an electromechanical integration sewing machine based on the development of electronic technology and computer control technology. The machine generally adopts a single-chip microprocessor as the core computer control system. In addition to the automatic auxiliary operation functions such as automatic thread cutting, automatic needle stopping, automatic dialing, automatic needle reversal, etc., it can also realize overlapping stitching and program of various styles. Seam. The computer-controlled electromechanical servo system's unique stepless speed regulation, gentle start, precise positioning, automatic fault diagnosis and display performance also bring great convenience to operation and maintenance. There are many types of computer sewing machines, which can be divided according to the functions of the control system.
There are five. Because the machine is a general sewing machine with variable sewing speed, some automatic functions of the control system can be set in advance or can be activated at any time. Therefore, the layout of the system is required to try not to change the appearance of the main operating part of the machine. To meet the operating habits of ordinary sewing machines, to ensure the convenience of use, adjustment and maintenance. If the operating panel, CPU box and floppy disk drive of the computer control section are mounted in the upper right corner of the head, it is both beautiful and convenient to operate. The advanced computer sewing machine mostly uses the all-digital vector AC servo motor as the driving device, and converts the pedal motion variable into the speed command through the foot sensor to change the frequency and voltage of the servo motor, so that the motor rotates at the required speed. In turn, the sewing machine is driven. In the speed control loop, the speed and current signals from the motor encoder and the current detector are used for feedback control, and vector control is performed thereby. When parking, first decelerate the motor, accept the signal from the synchronous detector, and perform closed-loop control based on the position signal from the encoder.
