This invention relates to a method and system for tobacco-related analysis based on visual information. The method involves converting and classifying the collected tobacco-related data, and then detecting and identifying tobacco types in tobacco-related images, extracting tobacco-related license plates from tobacco-related license plate images, and identifying and extracting tobacco-related text from tobacco-related text images. This, combined with personnel information and investigation data, enables rapid tobacco-related analysis of the collected data, helping to quickly identify key personnel.

This utility model relates to the field of cable tie technology and discloses an automatic cable tie machine using water-based adhesive for tobacco products. It includes a frame body, with support plates fixedly installed at the bottom of the left and right side walls of the frame body. A conveying mechanism is provided within the inner cavity of each support plate. First support blocks are fixedly installed on the left and right sides of the upper end face of the frame body. A center seat is fixedly installed within the inner cavity of each of the first support blocks on both sides. A lifting mechanism is provided on the lower end face of the center seat. Second support blocks are fixedly installed on the left and right sides of the front and rear of the upper end face of the frame body. A top seat is fixedly installed within the inner cavity of each of the second support blocks on both sides. A sealing mechanism is provided on the lower end face of the top seat. This utility model, through the conveying mechanism, can continuously transport bottles, cans, and packaging bags. Through the lifting mechanism, packaging bags on the conveyor belt can be adsorbed and lifted upwards. Finally, with the cooperation of the sealing mechanism, the packaging bags can be heat-shrink and tightened to achieve the sealing of bottles and cans.

This utility model discloses a real-time online correction device for preparing reconstituted tobacco using the slurry method. The correction device (1) includes a slider (11), a guide rail (12), a cylinder (15), a cylinder connecting push rod (16), and a displacement sensor (17). The cylinder connecting push rod (16) connects the slider (11) and the cylinder (15). The slider (11) is arranged on the guide rail (12), and a bearing (13) is located inside the slider (11). The bearing (13) is fixedly connected to the central axis of the correction roller (14). The guide rail (12) is arranged on the correction mounting frame (22). The correction roller (14) is arranged on the lower surface of the steel strip (3). The correction device of this utility model can achieve real-time online continuous correction during the preparation of reconstituted tobacco, ensuring the stability of the preparation of reconstituted tobacco.

This invention provides a method and system for grouping flue-cured tobacco using feature channel weighting and dynamic loss control, relating to the fields of deep learning and flue-cured tobacco grading. The method involves acquiring images of flue-cured tobacco from N main groups using an image acquisition device to establish a flue-cured tobacco grouping dataset, where N is a positive integer. This dataset is then preprocessed to obtain a preprocessed dataset. A flue-cured tobacco grouping classification network (TGNet) is designed and trained on the preprocessed dataset to obtain a flue-cured tobacco grouping classification model. Based on this model, the grouping results are obtained. This invention solves the technical problems of existing deep learning methods for flue-cured tobacco grouping, such as lack of key feature representation in high-scale features, limited inter-class discrimination ability, and a tendency for the model to learn from majority class samples during training. It achieves real-time classification of flue-cured tobacco groups, effectively improving the efficiency of flue-cured tobacco group classification and reducing the cost of manual grading.
