Background
China has become a big country for global corrugated board production, and corrugated boards are one of the most widely used material types in paper packaging in China. The corrugated board is a standard paper board formed by pressing, corrugating, gluing, bonding and shaping, separating and pressing lines and transversely cutting raw paper of a winding drum, and can be subsequently processed to be used as paper product packages such as cartons, supporting plates and the like. The production process of the corrugated paper has multiple links and complex process parameters. The main production process comprises the steps of raw paper supply, raw paper preheating, corrugation making, multiple preheating, sizing, hot pressing, drying, additional treatment, groove pressing, cutting and the like. In order to perform the above-described manufacturing process, it is necessary to make up a relatively complex corrugated paper manufacturing line, which generally has a stock frame, a paper feeding part, a preheating cylinder, a single facer, a multiple heating cylinder, a pulper, a sizing machine, a double facer, a line press, a crosscut machine, a stacker, and a steam heating system, an air compression system, a steam recovery system, etc. that supply high-temperature steam to the equipment involved in heating thereof.
In the production process of corrugated paper, the important process parameters comprise: the base paper type and gram weight, the base paper water content, the base paper preheating time and temperature, the corrugation type, the multiple preheating temperature and time, the sizing amount, the mucilage water content, the hot pressing pressure and temperature, the drying temperature, the surface additional process and the like all have important influences on the performance of the finally obtained corrugated paper product. Moreover, the process parameters have correlation of mutual matching and influence, for example, the water content of the mucilage has correlation with the subsequent hot pressing temperature and drying temperature; the moisture content of the base paper has direct relevance with the subsequent preheating time length, preheating temperature and the like.
Therefore, in order to ensure the quality and performance of the product, the corrugated paper production line needs to face the equipment, and the process parameters of the production process are monitored and regulated in time. With the development of the wireless Internet of things, the sensors of various types are installed on the production equipment of the corrugated paper production line and are connected into the wireless covered Internet of things, so that the real-time acquisition and feedback control of process parameters in the production process can be realized, and the data acquisition magnitude and the control response speed are greatly improved. However, due to the correlation between the process parameters, the adjustment of a single or a part of the process parameters may cause chain reaction of other production processes in the subsequent production line, thereby causing the state of the production line to fluctuate.
