Embodiment 1

[0048] Embodiment 1 detection device

[0049] Such as figure 1 As shown, the detection device includes a paving device 1, a paver 2 positioned below the paving device 1, an X-ray detector 3 positioned below the paver 2, and a visible light detector positioned below the exit of the X-ray detector 3 4. The material receiving device 6, the frame 5 and the control cabinet 7 located below the exit of the visible light detector 4;

[0050] The material spreading device 1 includes a main belt conveyor 1A, a load cell module 1B and a material limiting roller 1C, and the main belt conveyor 1A and the material limiting roller 1C are respectively driven by a geared motor. Four sets of load cell modules 1B are installed between the left and right sides of the main belt conveyor 1A and the frame 5 . The material limiting roller 1C is located at the discharge port of the main belt conveyor 1A.

[0051] The paver 2 can adopt a spring plate type vibration conveyor or an exciting vibration ...

Embodiment 2

[0058] Embodiment 2 detection method

[0059] The first step is to spread the material and weigh: first, take a sample according to the tobacco industry standard, and when it is used for the detection of the leaf structure or the stem content rate in the leaf, take a sample (3000 ± 300) g on the leaf collection conveyor belt after the leaf has been threshed and destemmed; When detecting the long stem rate or the leaf content rate in the stem, take a sample (1000-1500) g on the conveyor belt of the tobacco stems after threshing and destemming. According to the online or offline usage, the sample can be spread evenly on the material spreading device 1 by manual or upstream equipment, and then the mass of the sample can be automatically obtained by static weighing through the rail weighing system.

[0060] The second step is uniform feeding: start the equipment through the control cabinet 7, so that the material passes through the material spreading device 1, the paver 2, the X-r...

Abstract

The invention discloses a dual spectrum technology based leaf and stalk separating and cutting quality detection device and detection method. The detection device comprises a spreading device (1), a paving machine (2) arranged under the spreading device (1), an X ray detector (3) arranged under the paving machine (2), a visible light detector (4) arranged under the outlet of the X ray detector (3), a receiving device (6), a frame (5), and a control cabinet (7). The receiving device (6), the frame (5), and the control cabinet (7) are arranged under the outlet of the visible light detector (4).By adopting a visible light and X ray imaging technology and corresponding image algorithm, the tobacco leaf area, tobacco stalk area, and tobacco stalk length can be obtained; the leaves and stalks in a same image do not need to be separated, and the identification accuracy of image detection is improved. The leaf structure and long stalk rate can be detected, the stalk containing rate of leavesand leaf containing rate of stalks can be detected, the stalk density and leaf density are not needed during the index calculation process, and the leaf cutting quality indexes can be automatically calculated out.

Description

technical field [0001] The invention relates to the technical field of material detection in tobacco processing, in particular to a comprehensive quality detection device and method for threshing and destemming based on dual-spectrum technology. Background technique [0002] Tobacco leaves are composed of stems and leaves. The thick and hard veins of tobacco leaves are called stems, which account for about 25% to 30% of the tobacco leaves. The primary task of the threshing and destemming process in the tobacco threshing and rebaking process is to separate the leaves and stems of each tobacco leaf through special equipment, in which the leaves are separated into sheets of different sizes, and the stems are separated into long and short tobacco leaves. Different tobacco stem segments to meet the subsequent classification and processing requirements. [0003] According to the tobacco industry standard YC / T146-2010 "Technical Specifications for Threshing and Redrying of Tobacco...
