Quantitative detection method for filter stick spice line center distance

Abstract

The invention provides a quantitative detection method for a filter stick spice line center distance. The quantitative detection method for the filter stick spice line center distance comprises the following steps: (1) cutting at least one section of detection sample, (2) collecting and detecting an endface image of the detection sample by using image acquisition equipment and guiding the endface image into a detection software, (3) drawing a N regular polygon in the detection software to surround a filter stick in the endface image and continually correcting the size and position of the N regular polygon to enable the N regular polygon and the border of the filter stick to coincide so as to obtain a center point of the N regular polygon (N > = 25), (4) drawing a M regular polygon to surround a spice line in the endface image and continually correcting the size and position of the M regular polygon to enable the N regular polygon and the border of the spice line to coincide so as to obtain a center point of the M regular polygon (M > = 25). The center distance between the center point of the N regular polygon and the center point of the M regular polygon measured by the detection software is L. If the L is up to standard, the spice line filter stick is qualified. Otherwise, the spice line filter stick is unqualified. The quantitative detection method achieves quantitative detection and effectively controls the phenomenon that the filter stick explodes into the mouth.

Description

technical field [0001] The invention relates to the field of quality inspection of filter sticks, in particular to a quantitative detection method for the center distance of the fragrance line of filter sticks. Background technique [0002] With the gradual enhancement of people's awareness of environmental protection, in the cigarette manufacturing industry, most of the filter rods are used to further reduce the tar and harm of cigarettes, that is, to filter certain harmful substances in cigarette smoke. At the same time, in order to allow smokers to obtain different consumption experiences, spices such as floral and mint fragrances are usually added to the filter stick. At present, flavor threads are used in many cigarette filter rods. As a carrier of liquid additives, flavor threads can be added with essences, flavors, and liquid preparations for reducing tar and harm, and the threads of bright colors can be used to give people a special appearance. In addition, flavor t...

Problems solved by technology

As we all know, the spice itself has a strong softening effect on the hot melt adhesive. If the spice thread in the filter rod is not centered, there will be a softening of the joint, which will cause the filter rod to burst. Detection of the center distance between the filter rod and the spice thread

[0004] At present, the centering of the spice thread can only be distinguished by manual visual inspection, but cannot be quantitatively detected, so it is not conducive to controlling the bursting phenomenon of the filter rod

In addition, the subtle deviation of the fragrance line cannot be discerned by human visual inspection, so the improvement of its product technology is also adversely affected
