Method for measuring cigarette combustion cone parameters and standard kit

Abstract

The invention provides a method for measuring cigarette combustion cone parameters and a standard kit, and belongs to the technical field of cigarette detection. A standard component 1 and a standard component 2 are adopted, pixel values of the two standard components are obtained through a combustion cone measuring system, and a measurement transfer formula is established by combining parameters such as length, width and area of the corresponding standard components. The pixel value of the cigarette combustion cone area after combustion is obtained, the area of the cigarette combustion cone area is calculated through a measurement transfer formula, and the ash shrinkage rate is calculated in combination with the area of the cigarette combustion cone area before combustion; the pixel value of a crack area after the cigarette is burnt is obtained, the actual area of the crack area is obtained through a measurement transfer formula, and therefore the crack rate is obtained; and the actual position of a carbon line can be calculated by acquiring the pixel of the position of the carbon line, so that the uniformity of the carbon line is obtained. And the ash packing performance of the cigarette is evaluated through the ash shrinkage rate, the crack rate and the carbon line uniformity.

Description

technical field [0001] The invention relates to a method and a standard kit for measuring parameters of a cigarette combustion cone, belonging to the technical field of cigarette detection. Background technique [0002] The ash state of the cigarette paper when the cigarette is burned and the matching degree of the cigarette paper and the shredded tobacco when the cigarette is burned are the key parameters that affect the smoking experience of the cigarette. For cigarettes with poor ash wrapping effect, the burned cigarette paper is easy to crack and fall off during smoking and smoking, which is easy to cause ash to fall and splash. For cigarettes with poor matching between cigarette paper and shredded tobacco, the cigarette paper is first carbonized and then ashed when burning, resulting in carbonization of the combustion cone. If the circle is too wide and too dark, the combustion cone will fall or go out, which will directly affect the consumer's smoking experience. [0...
