Problems solved by technology

The low content of unqualified tobacco leaves and sundries in the laminar tobacco is the main reason for the large amount of labor and low operating efficiency in the existing selection mode
On the one hand, this mode of manual elimination results in huge staffing and difficult management. On the other hand, huge labor costs and personnel stability have become the main threats restricting the development of high-quality cigarettes.

Embodiment 1

[0028] Such as Figure 1-5 , a free-falling tobacco leaf sorting device, characterized in that it includes a conveying device, a frame 1, a chute 4, a rejection chute 2, an acceptance chute 8, a camera, a background roller 6, an image recognition module and Blowing and rejecting device; the chute 4, the rejecting chute 2, the accepting chute 8 and the camera device are all installed on the frame 1;

[0029] The conveying device is connected to the entrance of the chute 4, and the background roller 6 is arranged below the exit of the chute 4; It is arranged below the background roller 6, and the reject chute 2 is arranged on both sides of the side below the background roller 6;

[0030] The rejecting device includes a blowing nozzle 14 and a solenoid valve 13 that controls the air passage of the blowing nozzle 14. The solenoid valve 13 communicates with the air source; ; When the blowing nozzle 14 is blowing, the tobacco leaves are blown into the rejecting trough 2; when the ...

Abstract

The invention discloses a free falling type tobacco leaf sorting device and a tobacco leaf sorting method. The method comprises the following steps: enabling a tobacco leaf to fall down to a slide groove (4) from a conveying device and slide to a detection region in an accelerated manner through the slide groove; photographing an image of a tobacco leaf passing through the detection region by utilizing a CCD (Charge Coupled Device) photographing device; processing and identifying the image of the tobacco leaf through an image identification module; if identifying that the current tobacco leaf is unqualified, starting a solenoid valve in an air blowing eliminating device and blowing the current tobacco leaf to a rejection material groove (2) through a blowing nozzle (14); and otherwise, when the blowing nozzle (14) does not blow the air, enabling the tobacco leaf to freely fall down to an allowed material receiving groove (8) so as to realize the sorting of the tobacco leaf. The free falling type tobacco leaf sorting device and the tobacco leaf sorting method disclosed by the invention have the advantages of high sorting efficiency and high automation degree.

Description

technical field [0001] The invention relates to a free-falling tobacco leaf sorting device and a tobacco leaf sorting method. Background technique [0002] At present, in the production of cigarettes, manual selection is mainly used to ensure product quality. The artificial selection process of laminar tobacco is to manually remove unqualified tobacco leaves and sundries such as "green, mildew, miscellaneous" in laminar tobacco. The content of unqualified tobacco leaves and sundries in the laminar tobacco is very low, which is the main reason for the large amount of labor and low operating efficiency of the existing selection mode. On the one hand, this manual elimination mode results in huge staffing and difficult management. On the other hand, huge labor costs and personnel stability problems have become the main threats restricting the development of high-quality cigarettes. [0003] Therefore, there is an urgent need for an efficient, stable tobacco leaf sorting device...
