Description

Laser dot matrix device for detecting shape change of cigarette during combustion

Technical Field

The utility model relates to a laser measuring equipment, concretely relates to laser dot matrix device that shape changes when being used for detecting cigarette burning.

Background

With improvements in cigarette manufacturing and manufacturing processes, a wide variety of new types of cigarettes have emerged. The cigarette burning rate is the comprehensive reflection of the burning performance of the tobacco shreds and has a direct relation with the generation of various chemical components in the cigarette smoke. The speed of the instantaneous burning rate of the cigarette is closely related to the highest temperature of burning thermal cracking of the cut tobacco of the cigarette, and the generation and content change of smoke substances are directly influenced. The uniformity of cigarette combustion also reflects the quality of tobacco shreds and cigarette paper to a certain extent.

At present, image recognition determination methods are generally used for determining the uniformity of cigarette combustion.

Although the image recognition can accurately detect the spatial position change of an object, for the cigarette burning carbon line, the light generated by burning can cause great interference to the extraction of the characteristic points of the image, thereby causing the recognition deviation of the position of the actual burning carbon line. In order to accurately measure the shape change of the cigarette during combustion, the shape of the cigarette is positioned by adopting a laser dot matrix positioning mode in some prior art, so that the shape change of the cigarette in unit time can be effectively known, the position change of a combustion line during the combustion of the cigarette can be accurately obtained, and the combustion rate of the cigarette can be obtained. Most of the existing laser dot matrix positioning devices are integral, which is not beneficial to carrying and installation, and is difficult to adjust the dot matrix number of a unit space according to actual requirements, for example, the number of probes of the laser dot matrix can not be adjusted according to the body type change of cigarettes or cigars, and meanwhile, the laser dot matrix positioning devices are also not beneficial to quick and stable assembly and disassembly.

Therefore, a laser dot matrix device for detecting the shape change of the cigarette during combustion, which has the advantages of high measurement precision, quick assembly and disassembly, simple structure, good firmness after installation and capability of adjusting the number of laser dot matrixes in a dot matrix according to requirements, becomes necessary.
