The Development And Application Of System Of Coating Paper

Requirement of coated paper is progressively increased, so this article introduces the development process of the system of coated paper. At first, it introduces the mechanical component of the system of coated paper. Because there are many types of components, it selects components appropriately based on the demand of products. This system is made up of the mode of coating paper with rollers, drive system composed of steel net supported and three drivers, dryness system composed of oven with air floated and drying um with electric tubes, synchronous control system with the positions of strain rollers. And it developed an appropriate software of control system. This system achieves demands of operation, stabilization, continuity and high efficiency.This control system is based on the technology of IPC(Industrial Personal Computer) and PLC, the technology of frequency conversion and the technology of fuzzy-PID complex control. The software is programmed in according to the characteristic of modules, so this control system can run harmoniously and effectively.During the debuggig of this system, it analyses synthetically the rotate speed of drivers, the temperature of oven, the temperature of drying um and the positions of strain rollers. It educes a series of parameters, so the system is controlled in the status of fulfilling demands of operation.
