4. The main functions of the control system and their implementation

The main functions of the control system are as follows:

1. Automatic feeding function: There is no cloth in the steaming box, it is empty. At this time, the cloth is operated, and the cloth can not be opened later. The system can judge according to the fabric fullness signal. Once the fabric is full, stop immediately to prevent the cloth from being discharged. The cloth is caught in the main chain without opening. Avoid operators needing to observe the cloth at all times.

2, the cloth into the cloth self-adjustment function: the system sets the fabric full of acceleration, fabric full limit and other signals, when the system detects these signals, the cloth and the falling cloth can automatically adjust the speed to achieve the same length of cloth and cloth. .

3, the speed adjustment is convenient, the speed from the guide cloth speed to the production speed is short, and the production is stable. Steaming time adjustment range: 6-30 minutes.

4, the length of the loop can be adjusted, the actual loop length can be corrected.

5. Self-protection function and emergency cloth discharge operation: Self-protection means automatic shutdown when a fault occurs, preventing accidents from expanding. Emergency cloth discharge operation means that the cloth can be disposed in the case where the fault cannot be eliminated temporarily. All go out and deal with the fault to avoid unnecessary losses.

6, steaming temperature PID adjustment, control accuracy of ± 1 ° C

7. The fan speed can be adjusted freely according to the process requirements.

8, various process parameters can be backed up and saved, convenient for the next call.

9. The fault information can be queried, and there are fault handling measures for the operator to refer to.
