Abstract: Leather manufacturing requires the use of various leather chemical materials. The precise control of the ratio and dosage of leather chemicals can ensure the quality of the resultant leather and the stability of leather quality in different batches. In view of the fact that the batching of leather chemical materials still relies on the traditional and extensive manual batching mode, this paper mainly analyzed the application scheme of automatic batching system in leather production from the aspect of process control layer and field device layer by considering the actual application scenarios and functional requirements. Our aim is to provide a practical and feasible reference basis for the development and exploitation of automatic batching systems for leather industry.
