AI Technical Summary
Existing technologies in tobacco manufacturing are unable to effectively subdivide and frame tobacco leaves with different nicotine values, resulting in large differences in intrinsic quality attributes.
A tobacco leaf framing device is designed, which includes a fixed main conveyor belt, a primary conveyor belt, a secondary conveyor belt and multiple framing conveyor belts. By rotating the conveyor belts and adjusting the transmission direction, the tobacco leaves are classified according to nicotine levels and loaded into corresponding tobacco frames respectively. Accurate framing is achieved by combining with weighing sensors.
It enables the subdivision and framing of tobacco leaves with different nicotine values, and improves the accuracy of homogenization and internal quality control.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of tobacco manufacturing, and particularly relates to a tobacco leaf framing device. Background Art
[0002] At present, the homogenized operation mode for testing various parameters in tobacco manufacturing generally adopts the method of testing nicotine, sugar, characteristic values, etc. through online near-infrared equipment in the post-selection framing stage or the high-bay warehouse warehousing stage, and taking the single-frame average value for a certain factor or multiple factors. This method has realized the assignment and positioning operation of a single frame to a certain extent.
[0003] But taking nicotine as an example, due to the differences in nicotine content in different grades, varieties and origins, when the nicotine detection value of a certain box is 2.5, the nicotine content of the tobacco leaves in the box may contain all tobacco leaves with nicotine levels of 1.0-4.0. Considering an extreme case, half of the nicotine content in the box is 1.0 and half is 4.0. The average nicotine value after testing is also 2.5, which meets the numerical average of nicotine. However, there are huge differences in the intrinsic quality attributes represented by different nicotine levels.
[0004] To this end, it is necessary to "segment tobacco leaves with different nicotine values." Utility Model Content
[0005] The technical problem to be solved by the utility model is: how to design a tobacco leaf framing device that can frame tobacco leaves with different nicotine values separately, thereby realizing "segmentation of tobacco leaves with different nicotine values".
[0006] The technical solution of the utility model is specifically as follows:
[0007] A tobacco framing device includes a fixed main conveyor belt, a first-level conveyor belt is provided below the end outlet of the main conveyor belt, a framing conveyor belt is provided below one outlet of the first-level conveyor belt, a second-level conveyor belt is provided below the other outlet of the first-level conveyor belt, a framing conveyor belt is provided below each of the two outlets of the second-level conveyor belt, and a tobacco frame is provided below each of the two outlets of the three framing conveyor belts. The six tobacco frames are numbered No. 1, No. 2...No. 6 respectively.
[0008] A weighing sensor is provided under the cigarette frame.
[0009] Compared with the prior art, the technical effect of the present invention is that the multiple conveyor belts of the present invention can allow samples to reach multiple sampling frames, so that tobacco leaves with different nicotine values can be framed separately. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is a top view schematic diagram of the present utility model.
[0011] Figure 2It is a front view schematic diagram of the present utility model. DETAILED DESCRIPTION
[0012] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments thereof.
[0013] like Figure 1-2 A tobacco leaf framing device includes a fixed main conveyor belt 10, a first-level conveyor belt 21 is provided below the end outlet of the main conveyor belt 10, a framing conveyor belt 30 is provided below one outlet of the first-level conveyor belt 21, a second-level conveyor belt 22 is provided below the other outlet of the first-level conveyor belt 21, a framing conveyor belt 30 is provided below each of the two outlets of the second-level conveyor belt 22, and a tobacco frame 40 is provided below each of the two outlets of the three framing conveyor belts 30. The six tobacco frames 40 are numbered No. 1, No. 2...No. 6 respectively.
[0014] In order to conveniently measure the weight of the cigarette frame, a weighing sensor is provided below the cigarette frame 40 .
[0015] Its working principle is:
[0016] First, based on different origins, different grades, test data from previous years, and test data of samples, taking nicotine as an example, nicotine can be classified into six levels with different parameters, for example, a1-a2 is the first level, a2-a3 is the second level... a6-a7 is the sixth level, and the six-level classification distribution corresponds to the six cigarette frames 40, such as: the first level classification corresponds to cigarette frame No. 1, the second level classification corresponds to cigarette frame No. 2... the sixth level classification corresponds to cigarette frame No. 6.
[0017] Secondly, before framing, the classification of the tobacco leaves on the main conveyor belt 10 is determined by identifying the average value of the material data within unit time (which can be set as needed, such as 5 seconds, 10 seconds, etc.) or unit weight (an electronic belt scale needs to be added, such as 10 kg, 20 kg, etc.), and determining which tobacco frame it corresponds to based on its classification level.
[0018] Secondly, by adjusting the transmission direction of the first-level conveyor belt 21, the second-level conveyor belt 22, and the frame conveyor belt 30, the target cigarette frame is accurately reached. Figure 1 Taking the "tobacco frame" in the lower right corner of the figure as an example, the tobacco leaves on the main conveyor belt 10 fall on the primary conveyor belt 21, the primary conveyor belt 21 rotates left, and the tobacco leaves on the primary conveyor belt 21 fall on the secondary conveyor belt 22, the secondary conveyor belt 22 rotates left, and the tobacco leaves on the secondary conveyor belt 22 fall on the framing conveyor belt 30, the framing conveyor belt 30 rotates downward, and the tobacco leaves on the framing conveyor belt 30 fall into the framing frames.
[0019] Finally, after the cigarette frame is filled to the predetermined weight, the average, median, CV value, etc. of all the test data in the frame are calculated, and the data can be applied to different degrees according to different homogenization strategies.
[0020] Features of this application:
[0021] Compared with the current method of taking the average value of the entire frame to assign a single frame value, it can achieve the subdivision of nicotine and the subdivision of intrinsic quality under different nicotine properties, and can better achieve homogenized numerical control and intrinsic quality control.
[0022] For other contents, please refer to the prior art.
[0023] The above description is only the preferred embodiment of the present invention. It should be pointed out that those skilled in the art can make several changes and improvements without departing from the overall concept of the present invention, and these should also be regarded as the scope of protection of the present invention.
