TECHNICAL FIELD
[0001] The utility model relates to reconstituted tobacco technical field, specifically is a kind of reconstituted tobacco image acquisition conveying line. BACKGROUND
[0002] Tobacco tax contributes greatly to total tax revenue in China every year, but in order to improve the taste and reduce the tar produced by tobacco burning and the damage to the body of smokers, reconstituted tobacco made of tobacco stems, shredded tobacco leaves, and cigarette butts is added during the manufacturing process of cigarettes. Therefore, quality control of reconstituted tobacco is very important for the protection of the body of smokers and the sales of cigarettes. For reconstituted tobacco, due to the manufacturing process, the thickness can be well guaranteed within an error of ±0.2 mm, but it is difficult to have a specific index for the length. In the past, the average length was measured manually by measuring the length of a part of tobacco and then estimating the average length of the whole batch of reconstituted tobacco. This measurement method consumes a lot of manpower and material resources, and the accuracy of the measurement result is not guaranteed. The length of tobacco can be identified through tobacco images, but tobacco is usually gathered together, and it is difficult to distinguish directly by shooting, which affects the detection result.
