Method and a device for setting initial technological parameters of cigarette tobacco cutting

Abstract

The invention discloses a method and a device for setting initial technological parameters of cigarette tobacco cutting and relates to the technical field of tobacco processing. The method comprises the following steps: a step of obtaining production parameters of a production batch to be processed, a step of determining a reference batch which is matched with the production batch to be processedin processed production batches according to a preset matching rule and based on production parameters, and a step of setting the initial technological parameters of the production batch to be processed according to the technological parameters of the reference batch. Via the method and the device for setting the initial technological parameters disclosed in the invention, a processed production batch which is maximally close to a current production state and of which production results maximally meet requirements is used as the reference batch, technological parameters are extracted and usedas initial technological parameters of the production batch to be processed, and production of material heads is started; switch to PID control is made after a target value to be processed is stable,and therefore rapid and stable control over material head time during processing operation can be realized; fluctuation of tobacco quality during the material head time can be reduced, and product quality can be improved.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, in particular to a method and device for setting initial process parameters of shredded cigarettes. Background technique [0002] In the production process of shredded cigarettes, the output moisture content of each section is usually strictly controlled, especially the control accuracy of the moisture content of the dried shredded outlet is relatively high, and the final control effect of parameters such as the dried shredded outlet moisture content is usually controlled by PID process accomplish. PID control requires the material to reach the outlet from the equipment inlet and form a relatively stable output moisture content feedback before it can be adjusted and controlled. Before forming a relatively stable output water content feedback, it belongs to the material head time, and the water content within the material head time belongs to open-loop control. It is necessary to set a...

Problems solved by technology

This method of setting initialization process parameters is greatly influenced by human factors, and is easily affected by uncontrollable factors such as changes in the external environment, different moisture content of incoming tobacco leaves or shredded tobacco, etc., resulting in different control effects of outlet moisture content under the same set of parameters, resulting in The moisture content control of shredded tobacco within the material head time does not meet the process requirements, and leads to problems such as long PID adjustment time
