in the figure: the cigarette lighting device comprises a camera 1, a reflector 2, a light source 3, a light guide plate 4, a dustproof sheet 5, a cigarette to be detected 6, a shooting channel tube 7, a light transmission channel tube 8 and a polishing channel tube 9.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

As shown in figures 1-3, the visual inspection device for the tobacco shred end surface of the cigarette of the utility model is arranged at the position of the cigarette warehouse under the packing machine, the tobacco shred end surface faces the visual inspection device, the following is an embodiment of the utility model,

including the light channel pipe 9 of polishing that link up each other, pass light channel pipe 8 and shoot channel pipe 7, the direction of transfer of cigarette props up is length direction, be width direction with length direction horizontal perpendicular's direction, light channel pipe 9 and pass light channel pipe 8 level link up, it is provided with camera 1 to shoot channel pipe 7, pass light channel pipe 8 and shoot channel pipe 7 mutually perpendicular, and pass light channel pipe 8 and shoot the corner between channel pipe 7 and be provided with speculum 2, speculum 2 inclines along width direction towards the pipe tobacco terminal surface, 2 inclination of speculum in this embodiment are 45. Just in time place on the production line that is suitable for, the suitable narrow and small residual space of size just in time places this embodiment device.

The light irradiation channel tube 9 and the light transmission channel tube 8 are both in a flat rectangular shape, the length and the height of the light transmission channel tube 8 are both larger than those of the light irradiation channel tube 9, and the shooting channel tube 7 is arranged in the middle of the light transmission channel tube 8 in the length direction. The shooting channel pipe 7 is placed at the position, so that light rays reflected by the reflector 2 can be transmitted to the camera 1 as much as possible, visual detection images are clearer and brighter, and judgment of the end face condition of the cut tobacco is facilitated.

The connection surface between the polishing channel tube 9 and the light transmission channel tube 8 is provided with a light source 3, the upper surface of the polishing channel tube 9 is provided with a light guide plate 4, and the opening of the polishing channel tube 9 facing the end face of the tobacco shreds is provided with a transparent dustproof sheet 5.
