Servo control of bag making machine system

The bag making process is the last process in the flexible packaging printing production line, including positioning, fixed length, hot sealing, traction and sealing and cutting, and its process level directly affects the final product quality. In recent years, the domestic AC servo motor and other hardware technologies have gradually matured, and the high-computing control chip combined with the motor control technology has the characteristics of high efficiency, energy saving and good portability. This makes the AC servo system applied to the bag making machine control system. development trend. Below Anhui Yinsheng Electric Equipment Co., Ltd. tells you the following.

At present, the servo system mainly has the following characteristics:

1. Full digital control, powerful, three-loop control of position, speed and torque;

2. High-performance control chip, high-quality IPM module, perfect protection function;

3. Develop new algorithms to reduce software execution time;

4. The servo drive automatically determines the power and specifications of the servo motor and automatically sets the motor parameters.

5. Smooth operation at low speeds;

6. Communicate with the host computer through CAN, RS485 and RS232;

The continuous advancement of the servo motor manufacturing process has the advantages of low inertia, fast response, high power density, low loss, and high efficiency. The AC servo control system is a new technology developed in recent years and is developing into the mainstream of servo systems. The performance of the servo system is the main factor that determines the processing accuracy and productivity of the whole bag making machine. For the performance of the AC servo system, on the one hand, the fast tracking performance is required, that is, the servo system is required to respond quickly to the input signal, and the tracking error is small. The transition time is short, and there is no overshoot or overshoot, and the number of oscillations is small; on the other hand, the steady state accuracy is required to be high, that is, the system has small steady state error and high positioning accuracy.
