Loosening and moisture regaining water adding amount self-adaptive control system based on incoming material difference

Abstract

The invention discloses an incoming material difference-based loosening and moisture regaining water adding amount self-adaptive control system, and the main design concept of the system is as follows: through the training of a self-learning algorithm model, when the training precision reaches an optimization control target, a PID controller is used for carrying out the real-time automatic correction of the theoretical water adding amount of loosening and moisture regaining equipment, and the real-time automatic correction of the theoretical water adding amount of the loosening and moisture regaining equipment is realized. And accurate and reliable water adding control is provided. A self-adaptive system composed of a water adding film valve, a PID operation controller, an industrial personal computer, a data acquisition module, a bar code scanner, a tobacco bale with a bar code and a conveyor belt realizes information acquisition of different brands and batches of leaf group formulas, an acquired data information analysis model is applied to real-time control, and meanwhile, more-dimensional information is provided for subsequent research. The moisture content of an outlet of the loosening and moisture regaining equipment can be improved and more stable, the processing technology quality of tobacco leaves is improved, and the operation labor intensity of workers and the dependence on manual regulation and control experience can be greatly reduced.

Description

technical field [0001] The invention relates to the field of cigarette manufacturing, in particular to an adaptive control system for the amount of loose moisture and water added based on the difference of incoming materials. Background technique [0002] As the first processing process of tobacco silk production line, loosening and moisture regaining has a direct impact on the process indicators of subsequent processes. However, due to the different water absorption capacity of different grades of cigarettes, fluctuations in incoming material flow, measurement hysteresis, environmental temperature and humidity and other factors, export The volatility of moisture content is relatively large. [0003] At present, the control of moisture content in the loosening and reconditioning process is firstly to calculate the relevant parameters such as inlet moisture content, inlet material flow, outlet moisture content setting value, etc. to obtain the appropriate theoretical water ad...
