After the cigarette 7 is placed on the rotating carrier 3, the controller controls the rotating carrier 3 to start, then the rotating carrier 3 drives the cigarette 7 to rotate. The controller controls the light source assembly 4 to start, so that the light source assembly 4 can provide visible light and ultraviolet excitation light to the cigarette 7. Then the controller respectively controls the spectral camera 52 and the industrial camera 51 to start, so that the spectral camera 52 collects spectral information of the cigarette 7, and the industrial camera 51 collects detailed image information of the cigarette 7. The rotating carrier 3 drives the cigarette 7 to rotate, so that the light source assembly 4 provides visible light and ultraviolet excitation light to different parts of the cigarette 7. The spectral camera 52 can collect spectral information of different parts of the cigarette 7, and the industrial camera 51 can collect detailed image information of different parts of the cigarette 7.

[0024] The sealing door 2 can be a transparent glass door.

[0025] Specifically, when the transparent glass door seals the material inlet 131, it is convenient to observe the detection situation inside the housing 1 through the transparent glass door.

[0026] There may be two symmetrically arranged sealing doors 2. Two chutes are symmetrically arranged on the outer shell 1 and are respectively communicated with the material inlet 131. The two sealing doors 2 are respectively slidably connected to the two chutes. A handle 21 is respectively arranged on the front surfaces of the two sealing doors 2.

[0027] Specifically, the outer shell 1 includes a bottom plate 11, a top plate 12, a first side plate 16, a second side plate 17, a rear plate 15, a first display board 13, and a second display board 14. The top plate 12 is parallel to the bottom plate 11. The second side plate 17 is parallel to the first side plate 16. The first side plate 16 is perpendicular to the bottom plate 11. The rear plate 15 is perpendicular to the bottom plate 11. The first display board 13 and the second display board 14 are arranged up and down. The second display board 14 is perpendicular to the bottom plate 11. The first display board 13 is inclined. The area of the top plate 12 is smaller than that of the bottom plate 11. The bottom ends of the first side plate 16, the rear plate 15, the second side plate 17, and the second display board 14 are respectively connected to the bottom plate 11. The top ends of the first side plate 16, the rear plate 15, the second side plate 17, and the first display board 13 are respectively connected to the top plate 12. The bottom end of the first display board 13 is connected to the top end of the second display board 14. The first display board 13 and the second display board 14 together form the front of the outer shell 1. The rear plate 15 forms the back of the outer shell 1. The first side plate 16 and the second side plate 17 form the two side surfaces of the outer shell 1. The material inlet 131 is disposed through the first display board 13. The chutes are arranged at positions on the first display board 13 close to the material inlet 131. The two chutes are symmetrically arranged about the axis of the material inlet 131. The two chutes are respectively communicated with the material inlet 131. The two sealing doors 2 are respectively inserted into the two chutes, and the two sealing doors 2 can respectively slide in the two chutes. The mutually remote ends of the two sealing doors 2 are respectively slidably connected to the two chutes. When the mutually close ends of the two sealing doors 2 abut against each other, the material inlet 131 can be sealed. When the two sealing doors 2 move in the mutually opposite directions, the material inlet 131 is opened. The handle 21 is fixed to the sealing door 2. By pulling the handle 21, the sealing door 2 is pulled. A display screen 18 can be installed at a position on the first display board 13 above the first overlapping gap.

[0028] The rotary carrier 3 may include a support base 31 fixed to the inner bottom of the outer shell 1, two symmetrically arranged rotating rollers 32, two rotating shafts respectively connected to the two rotating rollers 32, and a power structure for respectively driving the two rotating rollers 32 to rotate in the same direction. The axes of the two rotating rollers 32 are parallel. The two rotating shafts are respectively rotatably connected to the support base 31. A first overlapping gap with a width of a first preset distance is provided between two mutually close portions on the side surfaces of the two rotating rollers 32. The two mutually close portions on the side surfaces of the two rotating rollers 32 are used to support the cigarette rod 7.

[0029] Specifically, the support base 31 is fixed on the bottom plate 11, and the axis of the support base 31 coincides with the axis of the bottom plate 11. The middle part of the rotating shaft on one rotating roller 32 is respectively connected to the inner side of the rotating roller 32. The two ends of the rotating shaft protrude from both sides of the rotating roller 32 respectively, and the two ends of the rotating shaft can be respectively connected to the support base 31 through bearings. The width of the first overlapping gap is a first preset distance, and the first preset distance is less than the diameter of the cigarette 7, so that when the cigarette 7 is placed on the two rotating rollers 32, it will not fall from the first overlapping gap. Then the two rotating rollers 32 can carry the cigarette 7, and the bottom parts of the cigarette 7 respectively abut against two adjacent parts on the sides of the two rotating rollers 32. The two rotating rollers 32 rotate in the same direction, that is, the two rotating rollers 32 rotate clockwise at the same time or the two rotating rollers 32 rotate counterclockwise at the same time. Then the two rotating rollers 32 can jointly drive the cigarette 7 to rotate. For example, when the two rotating rollers 32 rotate clockwise at the same time, the two rotating rollers 32 jointly act to drive the cigarette 7 to rotate counterclockwise; when the two rotating rollers 32 rotate counterclockwise, the two rotating rollers 32 jointly act to drive the cigarette 7 to rotate clockwise. The power structure includes two motors and two couplings. The two ends of one coupling are respectively connected to the output shaft of one motor and the rotating shaft on one rotating roller 32. When the two motors work, their speeds are the same, ensuring that the rotating speeds of the two rotating rollers 32 are the same, so as to better drive the cigarette 7 to rotate.

[0030] The light source assembly 4 may include a first connecting column 43, a second connecting column 44, a white light source 41 for emitting white light, and an ultraviolet light source 42 for emitting ultraviolet excitation. The white light source 41 is arranged above the ultraviolet light source 42. One end of the first connecting column 43 is connected to the white light source 41 and the other end is fixed at a first preset height inside the housing 1. One end of the second connecting column 44 is connected to the ultraviolet light source 42 and the other end is fixed at a second preset height inside the housing 1.

[0031] The spectral camera 52 and the industrial camera 51 can both be arranged above the rotating roller 32. The axis of the ultraviolet light source 42 is parallel to the axis of the white light source 41. The ultraviolet light source 42 is arranged above the rotating roller 32. There are two white light sources 41 symmetrically arranged about the axis of the first overlapping gap, and there are two ultraviolet light sources 42 symmetrically arranged about the axis of the first overlapping gap.

[0032] Specifically, along the direction from the front to the back of the outer shell 1, the industrial camera 51 and the spectral camera 52 are arranged in sequence, that is, the industrial camera 51 and the spectral camera 52 are arranged front and back. The axes of the industrial camera 51 and the spectral camera 52 can coincide, and the industrial camera 51 and the spectral camera 52 can be arranged directly above the first overlapping gap. The included angle between the light-emitting direction of the white light source 41 and the axis of the first overlapping gap is an acute angle, and the included angle between the light-emitting direction of the ultraviolet light source 42 and the axis of the first overlapping gap is an acute angle. The cigarette rod 7 is parallel to the bottom plate 11. The white light source 41 and the ultraviolet light source 42 are inclined with respect to the side surface of the outer shell 1, and the first connecting column 43 and the second connecting column 44 are inclined with respect to the bottom plate 11. The light rays emitted by the two white light sources 41 cross on the cigarette rod 7, and the light rays emitted by the two ultraviolet light sources 42 cross on the cigarette rod 7, so that the light rays emitted by the white light source 41 and the ultraviolet light source 42 can irradiate the cigarette rod 7.

[0033] The light source assembly 4 may further include a first light baffle 45, a second light baffle 46, and a third light baffle 47. The first light baffle 45 is respectively connected to the side surface of the white light source 41 close to the front of the outer shell 1 and the side surface of the ultraviolet light source 42 close to the front of the outer shell 1. The second light baffle 46 is respectively connected to the side surface of the white light source 41 close to the back of the outer shell 1 and the side surface of the ultraviolet light source 42 close to the back of the outer shell 1. One end of the third light baffle 47 is respectively connected to the first light baffle 45 and the second light baffle 46, and the other end of the third light baffle 47 is connected to the support base 31.

[0034] Specifically, the first light baffle 45 and the second light baffle 46 are symmetrically arranged, and the first light baffle 45 and the second light baffle 46 are perpendicular to the bottom plate 11. The first light baffle 45 can prevent light from being emitted to one side of the light source, the second light baffle 46 can prevent light from being emitted to the other side of the light source, and the third light baffle 47 can prevent light from being emitted in the direction of the bottom plate 11. The combined action of the first light baffle 45, the second light baffle 46, and the third light baffle 47 enables the light rays of the white light source 41 to irradiate as much as possible in the direction of the cigarette rod 7, and the light rays of the ultraviolet light source 42 to irradiate as much as possible in the direction of the cigarette rod 7.

The load-bearing plate 61 can be detachably connected to different heights inside the housing 1 by screws or bolts, so as to adjust the heights of the spectral camera 52, the industrial camera 51, and the light source assembly 4, and thus respectively adjust the distances between the spectral camera 52, the industrial camera 51, the light source assembly 4 and the cigarette rod 7. At least two side ends of the load-bearing plate 61 are respectively connected to the first side plate 16 and the second side plate 17 of the housing 1. It further includes a plurality of charging wires 65 arranged at the top end of the load-bearing plate 65.

One end of the first connecting column 43 away from the white light source 41 passes through the first set of rings 63 and extends out of one side of the first set of rings 63. Then, the portion of the first connecting column 43 located inside the first set of rings 63 and the first set of rings 63 are detachably fixedly connected by screws or bolt assemblies or screws. By adjusting the length of the portion of the first connecting column 43 away from the white light source 41 that passes through the first set of rings 63 and extends out of one side of the first set of rings 63, the first connecting column 43 can be fixedly connected to the first set of rings 63 at different positions, and the height of the position where the first connecting column 43 is connected to the first set of rings 63 can be adjusted, so as to adjust the height of the white light source 41 and realize the adjustment of the distance between the white light source 41 and the cigarette rod 7.

[0041] Specifically, this application pertains to the field of cigarette manufacturing and quality control. It delves deeply into the problem of yellow spots on cigarettes, aiming to assist cigarette manufacturers in accurately detecting and thoroughly analyzing yellow spots on cigarettes, thereby identifying problems in the production process and proposing effective improvement measures. Detecting yellow spots on cigarette paper may also include an analysis component for analyzing the causes of yellow spots by analyzing spectral information and detailed image information to obtain cause information about the yellow spots. The cause analysis performed by the analysis component includes, but is not limited to, identifying external pollution sources, thereby assisting production line workers in finding potential problems in the production process. The analysis component can be an embedded computer. This application can more effectively detect and analyze yellow spots on cigarettes, thus helping cigarette manufacturers improve the production process, enhance the quality of cigarettes, and reduce potential harm to smokers. In addition, this application has the advantages of fast detection speed, low single - detection cost, strong environmental adaptability, etc. It is simple to operate and can be directly used on the production line, facilitating production line workers to conduct real - time spot checks on cigarettes with yellow spots and analyze the causes of the yellow spots, thereby quickly discovering and solving problems on the production line and reducing the occurrence of yellow spots on cigarettes.

[0042] Specifically, two rotating rollers 32 drive the cigarette 7, enabling the cigarette 7 to rotate 360°, and all sides of the cigarette 7 are evenly illuminated.
