Technical Field
[0001] The utility model relates to a device for detecting shrinkage rate of baked tobacco leaves, belonging to the technical field of tobacco leaf shrinkage rate detection. Background Art
[0002] In the process of tobacco production, tobacco leaf baking is a crucial step. Its purpose is to control the synchronization of tobacco leaf water loss and drying process during baking, so as to bake high-quality tobacco leaf raw materials. During the baking process, tobacco leaves will shrink longitudinally and transversely due to water evaporation. This degree of shrinkage, namely shrinkage rate, is a key indicator for measuring the quality of tobacco leaf baking. Traditional tobacco leaf baking quality monitoring mainly relies on empirical judgment or indirect physical measurement methods, which often have large errors, low efficiency, and inability to achieve real-time monitoring. At present, most tobacco leaf baking process monitoring still uses traditional manual observation and regular sampling methods. These methods are not only time-consuming and labor-intensive, but also difficult to accurately grasp the degree and uniformity of tobacco leaf baking, and it is difficult to adapt to the current general direction and trend of intelligent and smart tobacco leaf baking.

[0022] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.
[0023] See also Figures 1 to 4 , this embodiment provides a device for detecting shrinkage rate of flue-cured tobacco leaves, including a tobacco hanging unit and a shooting unit.
[0024] The tobacco hanging unit includes a top plate 1, a back plate 2, a left baffle 3, a right baffle 4 and a hanger 5. The top plate 1, the left baffle 3 and the right baffle 4 are all grid structures and will not affect the airflow direction in the curing room. The left baffle 3 and the right baffle 4 are respectively installed on the left and right sides of the top plate 1 to block the influence of adjacent tobacco leaves on the detection. The back plate 2 is installed on the rear side of the top plate 1. The back plate 2 is formed by a plurality of longitudinal strips 21 and a plurality of transverse strips 22 crossing to form a grid structure, and the longitudinal strips 21 and the transverse strips 22 are respectively provided with scale values 23 along the length direction of both sides with their centers as starting points. Through these scale values 23, the length and width of the tobacco leaves during the baking process can be observed, thereby realizing the rapid detection of its shrinkage rate. The hanger 5 is installed on the front side of the top plate 1, and a hanging hole 8 is provided on the hanger 5. A hook 9 is provided on the top plate 1, and a clamping mechanism is installed at the bottom of the top plate 1, which includes a fixed plate 10, a movable plate 11 and a screw bolt 12. The fixed plate 10 is divided into two pieces and fixed on the bottom surface of the top plate 1 at intervals. The movable plate 11 can be movably arranged between the two fixed plates 10. One end of the screw bolt 12 is movably sleeved on the movable plate 11, and the other end extends out of the fixed plate 10 after passing through the screw hole on the fixed plate 10. The movable plate 11 can be driven to move by screwing the bolt 12, thereby achieving the clamping or loosening of the tobacco leaf stem.
[0025] The shooting unit includes a camera 6 and a lighting lamp 7. The camera 6 is installed in the hanging hole 8 and faces the back plate 2. The lighting lamp 7 is installed on the hanging bracket 5 and faces the back plate 2 to assist the shooting of the camera 6. For the convenience of control, the camera 6 is electrically connected to the baking controller, and the shooting of the camera 6 can be controlled by the baking controller to obtain photos of tobacco leaves at different baking times so as to judge their shrinkage rate.
[0026] The working principle of the above-mentioned flue-cured tobacco leaf shrinkage rate detection device is as follows:
[0027] Before baking the tobacco leaves, hang the tobacco hanging unit in the tobacco loading chamber, fix the camera 6 in the hanging hole 8, and hang the tobacco leaves in front of the back plate 2 and between the left and right baffles 4 through the clamping mechanism. During the baking process, photos of the tobacco leaves are continuously taken according to the set time intervals. The shrinkage rate of the tobacco leaves can be quickly judged by the scale values 23 of the vertical bars 21 and the horizontal bars 22 on the back plate 2.
[0028] After obtaining the scale values 23 of the vertical bar 21 and the horizontal bar 22, the tobacco leaf shrinkage rate can be calculated as follows:
[0029]
[0030]
[0031] Leaf area shrinkage rate = (tobacco leaf longitudinal shrinkage rate + tobacco leaf transverse shrinkage rate) - (tobacco leaf longitudinal shrinkage rate × tobacco leaf transverse shrinkage rate)
[0032] Compared with the prior art, the present invention can capture the changes of tobacco leaves in the baking process in real time by installing a shooting unit equipped with a camera 6 and a lighting lamp 7, and cooperating with a tobacco hanging unit. The length and width changes of the tobacco leaves can be accurately measured through the scale value 23 on the back plate 2, so as to calculate the shrinkage rate of the tobacco leaves. This monitoring greatly improves the accuracy of the data and the controllability of the baking process. In addition, the camera 6 can automatically control the shooting operation of the camera 6 through an electrical connection with the baking controller, reducing manual intervention and improving the convenience and efficiency of the operation. The user can set the shooting time interval as needed, and the system will automatically collect data.
