Background

In modern cigarette production, along with the continuous progress of science and technology, cigarette enterprises need to strictly control appearance flaws in packages, and strictly control product quality while producing packages at high speed. The production of one cigarette requires multiple receiving and outputting processes. In order to reduce the smoking resistance of the ramuscule cigarettes, improve the ventilation degree, reduce tar and the like, the ramuscule cigarette making and tipping machine set is additionally provided with a laser drilling device at the end of the online cigarette branch and the end of the filter tip.

Because the laser drilling of the cigarette is realized on line, the laser drilling equipment causes the loss of the laser drilling or the change of the laser aperture of the formed cigarette due to the accidental pollution of the laser head, thereby generating unqualified waste cigarettes. In the prior art, no laser drilling online detection equipment is used for fully detecting the laser drilling aperture of the cigarette at home and abroad, most of domestic cigarette factories adopt a mode of manually sampling a plurality of cigarettes at random time to observe to inspect the laser drilling of the cigarette, and the simple manual drawing inspection mode is not accurate and can not better play a role in detecting the whole quantity of cigarette production.
