Embodiment 1

[0024] Take a circular object with a known area S0 as a standard object, and place it on a flat, smooth, opaque white background board. The feed solution was applied to the background plate and photographed. Open the photographic result in Image-proplus; use Image-proplus to select the measurement item and measurement area to obtain the corresponding pixel value. The image number of the standard object is represented by P 0 Indicates that the pixels that detect granular stems are denoted by P 1 express. S 1 The pixel calculation formula is S 1 =S 0 *P 1 / P 0 . The particle size D of a single particle stalk 1 =(4*S 1 / Pi) 0.5 . The calculated droplet size is shown in Table 1:

Abstract

The invention discloses a detection method for particle sizes of atomized droplets of feed liquid. The detection method is characterized in that digital treatment is carried out on a preprocessed particle size picture of atomized droplets of feed liquid by using an Image-proplus image treatment technology, so as to obtain the particle sizes of the atomized droplets in a calculation manner. The problem of atomization effect evaluation of the feed liquid in cigarette enterprises is solved, a simple and feasible determination method is provided for accurate, objective, concise and efficient evaluation of the atomization effect of the feed liquid, reliable technical parameters and evaluation data are provided, and the detection method has important significance on control of production process stability, feeding uniformity and cigarette quality indexes.

Description

technical field [0001] The invention relates to the technical field of cigarette production, in particular to an image detection method for the particle size of atomized droplets of feed liquid. Background technique [0002] Feeding is an important process in the cigarette production process. Its task is to apply the feed liquid to the cigarette sheets evenly and effectively according to the requirements of production and formula. The uniformity of feed liquid application is an important factor affecting the quality, taste and style of cigarette products. . [0003] At present, in the tobacco industry, the feeding accuracy is usually used to measure the quality of the feeding. The feeding accuracy is the percentage of the difference between the overall feeding amount and the set feeding amount compared with the set feeding amount. This means that the feeding accuracy can only reflect the difference between a batch of material feeding and the expected difference, but cannot ...
