Embodiment Construction

[0049] Such as figure 2 Shown, the present invention comprises the following steps:

[0050] A. Sample tipping paper gluing: the specific process is:

[0051] a1: Select sample tipping paper, the color of the glued side of the selected sample tipping paper is different from the color of the tipping glue in the dry state;

[0052] a2: Under the normal production conditions of the glue applicator, apply the tipping glue on the glued surface of the sample tipping paper;

[0053] B. Cigarette rolling with sample tipping paper: roll under the normal production conditions of the cigarette machine and tipping machine, and then use the glued sample tipping paper to overlap to obtain a cigarette sample;

[0054] C. Take N sample cigarettes: after the speed of the cigarette making machine is stable, take N cigarettes from the cigarette samples produced in step B as sample cigarettes;

[0055] D. Obtain sample cigarettes X i The glue-free zone area B i , i=1,2,...,N; sample cigaret...

Abstract

The invention discloses a method for detecting the compliance rate of cigarette glue-free areas based on an image detection method. By selecting a sample tipping paper with a large color difference from the tipping glue, the sample roll is used under the normal production conditions of the cigarette machine and the tipping machine. Load paper for cigarette rolling, and then sequentially undergo sampling and collection of the area of ​​the glue-free area of ​​the sample cigarette, and obtain the shape and area of ​​the glue-free area through image acquisition; the invention can quickly, conveniently and accurately detect the shape of the glue-free area and the area of ​​the glue-free area. area, solve the problem of lack of information on perforated cigarettes, provide accurate data support for the adjustment of equipment parameters, ensure the ventilation effect of finished cigarettes, and improve the qualified rate of finished cigarettes.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, in particular to a method for detecting the compliance rate of the glue-free area of ​​cigarettes based on an image detection method. Background technique [0002] At present, filter ventilation and dilution technology is the most common method of coke reduction in the industry. It is generally divided into pre-punched cigarettes and online perforated technology. Pre-punched cigarettes use tipping paper that has been punched with one or more rows of holes , Online drilling generally adopts online laser drilling technology. There are many factors that affect the ventilation path during the cigarette rolling process. Therefore, in order to ensure the stability of the ventilation rate of the filter, it is necessary not only to ensure the stable ventilation of the filter section and the cigarette section, but also to ensure the suction resistance at both ends. Among them, The most importa...
