Embodiment 1

[0022] Take the shredded and shredded process of one specification cigarette as the sampling point, and the designed shredded width is 1.0mm. Then proceed as follows:

[0023] (1) After the processing equipment is stabilized, one tobacco leaf sample is taken before the shredder, and 30 shredded tobacco samples are taken at intervals of about 1 min after the shredder. Take a piece of tobacco leaf from the tobacco leaf sample, spread it out, and cut out a small rectangular piece of about 15.4 mm × 9.5 mm with scissors, which is regarded as a control sample; at the same time, from 30 shredded tobacco samples, each selected one has no adhesion and the length reaches A total of 30 shredded tobacco over 15mm. The control sample and 30 shredded tobacco were flatly pasted on the background template using solid glue in accordance with the principle of non-overlapping.

[0024] (2) Place the background template pasted with the control sample and shredded tobacco horizontally on the sh...

Embodiment 2

[0035] Taking the shredded and shredded process of another specification cigarette as the sampling point, the designed shredded width is 0.9mm. Then process according to the method in embodiment 1, contrast sample area pixel value is 55001, contrast sample actual area 146.3mm 2 , and the cut widths of each shredded tobacco sample are shown in Table 2. According to the cutting width of the cut tobacco samples in the table, the average value of the cut tobacco width is calculated It is 0.9446mm, and the cutting uniformity CU is 89.44%.

Abstract

The invention discloses a method for analyzing the uniformity of shredded tobacco leaves. , digitize the images of the control sample and the shredded tobacco sample respectively, and obtain the sample area pixel value of each control sample, as well as the sample area pixel value and sample length pixel value of the shredded tobacco sample; 3) Use the formula to calculate the shredded width of each shredded tobacco sample ; 4) On the basis of obtaining the cut width of the cut tobacco sample, use the formula to calculate the cut uniformity of the tobacco leaf. The present invention solves the problem of accurately measuring the uniformity of cut shreds in current cigarette enterprises, provides a simple and feasible measurement method for accurate, objective, concise and efficient evaluation of shredded width, and provides reliable technical parameters and evaluation data. It is of great significance to control the stability of the production process, the uniformity of the shredded width and the quality index of cigarettes.

Description

technical field [0001] The invention belongs to the technical field of cigarette product quality monitoring, and in particular relates to a method for analyzing the uniformity of shredded tobacco leaves. Background technique [0002] In the process of cigarette production, timely and accurate monitoring of product uniformity and stability is of great significance for improving the quality of cigarette products. At present, most domestic cigarette companies can only test the end products of cigarettes, and lack accurate monitoring and measurement methods for process control accuracy. Therefore, the tobacco industry is particularly concerned about the refinement of the silk-making process. As an important process in cigarette processing, the shredding process is directly related to the shred width of the tobacco leaves. Shred width is one of the main factors affecting the sensory quality and physical quality of cigarette products, and its uniformity and stability are related...
