Abstract
In nowadays , the papermaking profession in our country is occupying the development phase, in our province most of the papermaking enterprise are the small and medium-sized enterprise. Because shortage of capital, the weakness in technology, the middle and small scale paper mill was still using the multi-point control mode to carry on the transmission, its working strength is mass, the working efficiency is low, the real-time control difference, which is continually could not adapt to the enterprise's economy and the social efficiency.
The paper machine equipment existing in the small papermaking enterprise，whoes working efficiency is low in view of present, the synchronism is inefficient , as well as the Small and medium-sized enterprise faces generally fund shortage, technology weak and so on problems, this paper proposed the construction based on the configuration software's energy conservation paper engine drive control system's plan. Through using the touchscreen, PLC, the frequency changer and the superior machine constructs the third-level control structure the paper engine drive control system, and completes between the system each module's connection connection, the PLC port design, frequency changer's establishment, configuration work and so on software and PLC programming and debugging, constructs the complete paper engine drive control system, can finally completes through the touchscreen and the superior machine simple human-machine interface to system's transmission part carries on opens stops, controls and so on velocity modulation, and carries on the system monitoring. This system can effective enhance the paper machine systems operation the stability and the working efficiency, the human-machine interface simplicity of operator easy to study, can carry on easily to the paper machine system modulates velocity precisely, the system becomes easier to monitor, the stable papermaking equipment may improve the papermaking quality, and saved the energy loss to a certain extent.
Paper engine drive system based on configuration software can meet the needs to the small and medium-sized enterprise in all about the machine system’s working efficiency, stability and it’s economy. Therefore, there will be a big development opportunities in the future in the small papermaking enterprise.
