First of all, the processing capability of PLC non-woven equipment and the program logic of processing capability, which are characterized by modularization and standardization in program design, debugging and modification, only need to modify the corresponding modules to make it easy to read, structure, and more importantly is to facilitate the debugging process. The PLC program is the key to the operation of the system, which determines the organic progress of the entire circuit; secondly, it is aimed at the problem of human-computer interaction. In the main interface, use the script keyboard to realize the function shortcut keys, click the touchpad to switch to the screen of each extension, and realize the man-machine dialogue. The production line is fast and requires high synchronization. In the design, this feature should be fully considered. Therefore, a synchronous control method is adopted. The data content of the inverter of the laying machine and the winding machine is exchanged mainly through the data interface of the PLC. In order to achieve a satisfactory dynamic effect, digital communication and production lines must be realized, and increasing the speed is a good dynamic effect. In order to ensure the synchronization function of the laying machine and the winding machine, the winding machine is also equipped with a tension control system. The tension of the winder is a very important link, and the tension control is increased on the basis of synchronous control. It plays a great role and affects the quality of the product to a large extent, and the stability of the tension of the winding machine is also one of its influencing factors. Then, the tension controller is particularly important. It can transmit the control signal to the PLC, and then strictly adjust the control program through the tension and tension control system to ensure the dynamic stability of the tension control of the winding machine.

The touch screen human-computer interaction system is also very important, it is an important part of the production line. The touch screen provides a very advanced and user-friendly human-computer interaction interface. When operating, click the screen on the touch screen, and then the corresponding menu will pop up, which is very convenient. The main parameters and working status of the dynamic display device can be modified and set at the same time. The main functions include display function, parameter setting, historical trend record, alarm query, report making, authorization management and online help.
