Abstract

The invention is applicable to the field of detection for the air permeability of tipping paper and provides an online detection system and method by laser perforation on tipping paper. The system comprises an image sensor and a back light plate which are oppositely placed, wherein the tipping paper to be detected is arranged between the image sensor and the back light plate; and micropores are perforated in the surface of the tipping paper according to the requirement. The system also comprises a computer connected with the image sensor, wherein the image sensor is used for capturing a micropore arrangement image on the surface of the tipping paper; and the computer is used for calculating the total area of the micropores in the micropore arrangement image and calculating the air permeability value of the tipping paper to be detected according to a calibrated area-air permeability relation. The online detection system and method provided by the invention have the advantages that the photoelectronic imaging is adopted, the air-permeability value is calculated according to the total area of the micropores, the accuracy of a measurement result is high, the measurement time is short and the production efficiency is high; and the structure is simple, the implementation is easy, and the measurement efficiency and the measurement accuracy can be improved, so that the application value is extremely large.

Description

technical field [0001] The invention belongs to the field of air permeability detection of tipping paper, and in particular relates to an online detection system and method for laser punching of tipping paper. Background technique [0002] Air permeability is a very important quality index of tipping paper. The air permeability of tipping paper is an important indicator used by cigarette factories to reduce harmful substances such as nicotine, cigarette tar and carbon monoxide in tobacco. With the improvement of people's living standards and different health requirements, cigarette factories have proposed to reduce tar and eliminate harm, and produce cigarettes with low tar content. Therefore, the requirements for air permeability of cigarette paper are getting higher and higher. Laser drilling is the current stage. Cigarettes take one of the most extensive ways to reduce tar content. At present, all laser-punched tipping paper air permeability detectors in the market are ...
