[0024] like Figure 1-Figure 4 As shown, an embodiment of the present application provides a debris identification device for use in a tobacco conveying process. The debris identification device 3 includes a frame 303 , a mounting portion 301 , an image acquisition device 304 , a driving device 306 and a pulley 308 .

[0025] The frame 303 is provided with a plurality of slide rails 302 parallel to each other on its periphery. The slide rails 302 are used to set the mounting portion 301. The slide rails 302 may be cylindrical and may be arranged inside the frame 303. When the debris in the tobacco is identified by the debris identification device 3, the frame 303 is arranged above the conveying mechanism 2 for conveying the tobacco. The frame 303 may be a rectangular frame, and the slide rails 302 may be arranged at the triangles in the four corners inside the rectangular frame. For example, the frame 303 may be a gantry frame, and the gantry frame 303 spans across the two sides of the conveying mechanism 2. Of course, the frame 303 may also be other structures, and the frame 303 can ensure that the image acquisition device 304 is located above the conveying mechanism 2. In the present application, the conveying mechanism 2 may be a conveyor belt, and the conveyor mechanism 2 may be a conveyor belt with a height difference at both ends, and at this time, the conveyor belt forms a certain slope. The conveying mechanism 2 may be a part of the debris identification device 3. In this case, the debris identification device 3 may be connected to the production line to identify the debris. Of course, the conveying mechanism 2 may not be a part of the debris identification device 3. In this case, the debris identification device 3 may be directly installed on the original conveyor belt of the production line. In some embodiments, the conveying mechanism 2 may include a plurality of legs 1, and the plurality of legs 1 may provide stable support for the conveying mechanism 2. The mounting portion 301 is slidably connected to a plurality of slide rails 302. When the mounting portion 301 slides along the slide rails 302, the distance from the conveying mechanism 2 can be changed. The image acquisition device 304 is disposed on the mounting portion 301. The image acquisition device 304 is used to acquire images of tobacco shreds on the conveying mechanism 2. For example, the image acquisition device 304 may be a camera. The number of the image acquisition device 304 may be one or more. The image acquisition device 304 is communicatively connected to a processor for identifying debris in tobacco shreds. The mounting portion 301 is used to mount the image acquisition device 304. The mounting portion 301 is positionally adjustable through the slide rail 302. When the mounting portion 301 changes position, it can drive the image acquisition device 304 mounted thereon to move together, so that the image acquisition device 304 can obtain an image for identifying debris in the tobacco. After the image acquisition device 304 obtains the image of the tobacco, it transmits the image to the processor for processing. The processor uses an AI artificial intelligence deep learning algorithm to identify debris in the tobacco, thereby facilitating the discovery and removal of debris. The processor can be a processor of an external terminal system, and the external terminal can provide a friendly human-computer interaction page, which can view the images and recognition results collected by the image acquisition device 304 in real time.

[0026] The driving device 306 is arranged on the frame 303, the pulley 308 is rotatably arranged on the frame 303, and is connected to the output end of the driving device 306 through the synchronous belt 307. The pulley 308 can be rotatably connected to the frame 303 through a bearing, and the extension direction of the straight portion of the synchronous belt 307 is parallel to the slide rail 302, wherein the mounting portion 301 is fixedly connected to the straight portion of the synchronous belt 307. In this embodiment, the driving device 306 can be a driving motor, and a driving wheel can be installed on the output shaft of the driving motor. The driving wheel is connected to the pulley 308 through the synchronous belt 307. The driving wheel and the pulley 308 are arranged at intervals, and the portion of the synchronous belt 307 located between the driving wheel and the pulley 308 forms a straight portion of the synchronous belt 307. The mounting portion 301 is fixedly connected to the straight portion. When the driving wheel drives the pulley 308 to rotate through the synchronous belt 307, the straight portion of the synchronous belt 307 moves linearly, thereby driving the mounting portion 301 to slide along the slide rail 302. The driving device 306 may be communicatively connected to a processor of an external terminal system.

[0027] The embodiment of the present application provides a debris identification device 3 for use in the tobacco conveying process. The image acquisition device 304 installed on the installation part 301 acquires images of the tobacco passing through the conveying mechanism 2. After the image acquisition device 304 transmits the image to the processor, it uses the AI ​​artificial intelligence deep learning algorithm to complete the identification of debris in the tobacco, thereby improving the identification efficiency. At the same time, the installation part 301 can drive the image acquisition device 304 to change the distance from the conveying mechanism 2 to adapt to different tobacco thicknesses and conveying mechanism 2 heights, thereby improving the applicability of the debris identification device 3.
