Problems solved by technology

[0005] However, the above-mentioned method has not yet been applied on a large scale, because: 1) the tobacco leaves are required to be very flat, but the actual tobacco leaves are naturally shrunken; Under the circumstances, the tobacco leaves are required to advance at medium and high speeds on the leaf laying table, so this method cannot meet the needs of industrialization and process production; 3) The identification accuracy and efficiency of the above method are affected by many factors such as the light intensity of the light source, the color temperature of the light source, and the site environment.

Embodiment 1

[0039] Such as Figure 1-3 As shown, this embodiment provides a tobacco leaf subdivision device based on nicotine content, including a conveyor belt module, the conveyor belt module includes a plurality of conveyor belts 1, and the multiple conveyor belts 1 form a plurality of bifurcated structures arranged in sequence , each of the bifurcated structures includes three sections of conveyor belts 1 arranged in a Y shape; the front end of each bifurcated structure at the bifurcated position is provided with a detection device 2 and a diverter, the The detection device 2 is used to detect the nicotine content of the tobacco leaves 3, and the diverter is used to control the conveying direction of the tobacco leaves 3; the forked structure at the front end is used to connect the leaf laying platform.

[0040] preferred, such as Figure 2-3 As shown, the diverter includes a turning baffle 5 and a controller 4, the controller 4 is connected with the turning baffle 5 and the detectio...

Embodiment 2

[0053] This embodiment is an improvement made on the basis of Embodiment 1. The improvement is that: in this embodiment, in steps 2) and 3), a is 0.1%, and n is 10. In this embodiment The tobacco leaf 3 subdivision method based on nicotine content comprises the following steps:

[0054] 1) Before threshing, set the most suitable nicotine content value (represented by a) according to the cigarette formula, tobacco leaf production area, tobacco leaf position and other factors;

[0055] 2) Disassemble the cigarette pack, and after heating and humidifying, make the tobacco leaves 3 basically reach the water content suitable for processing (15-17%); then disperse the tobacco leaves 3 on the leaf laying table; Crawler 1 advances under the effect of the frictional force of transmission crawler 1; a near-infrared (infrared) spectrometer is set above each bifurcation position of transmission crawler 1 to detect the nicotine content of tobacco leaf 3 (instant nicotine content), followe...

Abstract

The invention discloses a tobacco leaf subdivision device and method based on nicotine content, and relates to the technical field of tobacco leaf sorting. The device comprises a conveying crawler belt module, the conveying crawler belt module comprises multiple sections of conveying crawler belts, the multiple sections of conveying crawler belts form multiple forked structures arranged in sequence, each forked structure comprises three sections of conveying crawler belts which are arranged in a Y shape; a detection device and a direction changer are arranged at the front end of the forking position of each forking structure, the detection device is used for detecting the nicotine content of the tobacco leaves, and the direction changer is used for controlling the conveying direction of the tobacco leaves; and a forked structure at the foremost end is used for being connected with a leaf laying table. The tobacco leaves are sorted by taking the nicotine content of the tobacco leaves asa sorting index, so that the nicotine uniformity of the tobacco leaves is improved, and large-scale and process processing is realized.

Description

technical field [0001] The invention relates to the technical field of tobacco leaf sorting, in particular to a tobacco leaf subdivision device and method based on nicotine content. Background technique [0002] Due to subjective and objective factors, the tobacco leaves sold by farmers are often mixed with many grades of quality tobacco leaves, so the nicotine content of a batch of tobacco leaves (uniformity of nicotine content is a necessary condition for cigarette style and quality stability) varies from high to low. , with poor uniformity. In order to ensure the uniformity of tobacco leaf raw materials and the stability between batches, industrial companies need to sort tobacco leaves. [0003] At present, the tobacco leaves are generally sorted according to the appearance characteristics of the tobacco leaves. This process is a time-consuming and labor-intensive process. In addition, the labor price continues to rise, so the mechanized sorting of tobacco leaf raw mater...
