Temperature control method and spraying device for surface layer spraying liquid of composite six-layer paperboard

The invention belongs to the technical field of packaging material processing, and particularly relates to a surface layer spraying liquid temperature control method and spraying device for a composite type six-layer paperboard, and the method comprises the following steps: collecting section size data and process flow data of a five-layer paperboard serving as a substrate to obtain a first data set; collecting formula data, performance data and spraying requirement data of the spraying liquid to obtain a second data set; real-time parameters, including the temperature and humidity of the surface, of the position to be sprayed are collected at the set production position, and a third data set is obtained; converting the data set to obtain three vectors respectively; corresponding weights are given to the three vectors, results are input into a neural network model, and the neural network model is used for outputting the temperature control value of the spraying liquid. According to the method, the technical e
