Method for improving batch procedure capability of tobacco shred making process

Abstract

The invention relates to a method for improving the batch procedure capability of a tobacco shred making process, comprising the following steps of: acquiring original data of multiple process parameters of each device in a tobacco shred production line; respectively calculating procedure capability index of each process parameter; converting the procedure capability index of each process parameter to obtain a process regulation reference value of the each process parameter; carrying out the weighted mean on the process regulation reference value of the each process parameter to obtain an evaluation value of the batch procedure capability of the current batch of a corresponding device; obtaining an assessed value of the batch procedure capability of the current batch of the tobacco shred production line by the weighted mean; and judging whether the assessed value of the batch procedure capability of the current batch of the tobacco shred production line is up to a preset threshold; ifthe assessed value is not up to the preset threshold, detecting whether the process regulation reference value of the each process parameter in the current batch of the each device in the tobacco shred production line is up to the preset threshold, and regulating the process parameters which are not up to the preset threshold.

Description

technical field [0001] The invention relates to a technology for optimizing the quality of the shredded cigarette processing process, in particular to a method for improving the batch process capability of the shredded shredded process. Background technique [0002] The silk-making process is the core link in the cigarette manufacturing process. Through the design of the rationalized process of the silk-making process, under the control of the optimal combination of various process parameters, the internal quality of cigarettes can be effectively improved or improved. [0003] At present, various industrial companies in the tobacco industry have adopted a relatively fixed mode and state for the optimization of various process parameters in the silk-making process according to the needs of their own brands, but the evaluation and optimization of the process batch quality in the entire silk-making process still remains to be done. There is no relatively mature and effective me...

AI Technical Summary

Problems solved by technology

[0004] In the actual silk-making process, there are many parameters that affect the internal quality of cigarettes. The method of evaluating and optimizing by random inspection or sampling is relatively one-sided, and cannot well reflect the current production process in the silk-making process. The process quality of the machine, etc., making it difficult to make targeted optimization adjustments

In addition, since it is difficult to find out specific defects, it often requires technicians with rich experience to give corresponding optimization solutions. For technicians with less experience, it is obviously very difficult and often requires more cost. A good optimization effect can only be achieved by repeated experiments with a large number of man-hours, which will inevitably increase the labor cost and time cost of the optimization process.
