[0002] Tobacco leaf grading is a crucial step in tobacco production, and achieving full automation is extremely challenging. However, the primary prerequisite for achieving fully automated grading is how to continuously and uninterruptedly supply tobacco leaves to the automatic grading equipment, ensuring that the supplied tobacco leaves are flat and neat. Currently, commonly used tobacco leaf grading equipment often uses belt conveyors, pneumatic systems, or a combination of the two to continuously supply tobacco leaves to image acquisition and recognition devices. However, in actual operation, belt conveyors often require manual loading of tobacco leaves one by one, which requires high labor input, is inefficient, and can easily lead to dry cycles due to lack of coordination between humans and machines. While pneumatic systems can supply tobacco leaves individually, they require a large amount of compressed air, consume a lot of energy, and can easily damage or disrupt the tobacco leaves. Therefore, a continuous tobacco supply mechanism is highly desirable. Utility Model Content

[0019] In order to make the technical problems and technical solutions solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention.

[0021] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0022] like Figures 1 to 4 As shown, this embodiment provides a tobacco leaf grading and continuous smoke supply mechanism, including a frame 1, on which are installed a screw linear guide module I20, an auxiliary guide rail I22, a screw linear guide module II30 and an auxiliary guide rail II32, the screw linear guide module I20 and the auxiliary guide rail I22 are installed at one end of the frame 1, the screw linear guide module II30 and the auxiliary guide rail II32 are installed at the other end of the frame 1, a smoke supply box I23 is installed on the screw linear guide module I20 and the auxiliary guide rail I22, a smoke supply box II33 is installed on the screw linear guide module II30 and the auxiliary guide rail II32, and a servo motor I21 and a servo motor II31 are respectively installed at both ends of the screw linear guide module I20 and the screw linear guide module II30 near the edge of the frame 1.

[0023] In this way, two sets of lead screw linear guide rail modules and auxiliary guide rails slide the two cigarette supply boxes onto the slide. The servo motor drives the lead screw to rotate, thereby driving the cigarette supply boxes to reciprocate along the guide rails, moving to the working position 6 for cigarette supply or the waiting position 7 for cigarette loading. Of course, while achieving the same technical effect, other linear transmission mechanisms can also be used to replace the lead screw linear guide rail modules and auxiliary guide rails, such as electric cylinders, hydraulic cylinders, pneumatic cylinders, electric push rods, guide-type linear motors, etc.

[0024] When tobacco is needed, the tobacco leaf pile is loaded into the tobacco supply box Ⅰ23, and the servo motor Ⅰ21 is started to drive the screw of the screw linear guide module Ⅰ20 to rotate, and the slide connected to the screw begins to move along the screw, thereby driving the tobacco supply box Ⅰ23 on the slide to move together. At the same time, the slide connected to the tobacco supply box Ⅰ23 on the auxiliary guide rail Ⅰ22 also slides together, thus ensuring that the tobacco supply box Ⅰ23 moves smoothly in a straight line and moves to the working position 6 to supply tobacco, so that the leaf grading equipment can grab a single tobacco leaf for identification and grading. When all the tobacco leaves in the cigarette supply box I 23 are grabbed, the servo motor I 21 is controlled to rotate in the opposite direction, so that the cigarette supply box I 23 returns to its own waiting position 7 to load cigarettes. At the same time, the servo motor II 31 is started to drive the screw of the screw linear guide module II 30 to rotate, thereby driving the cigarette supply box II 33 to move linearly along the guide rails of the screw linear guide module II 30 and the auxiliary guide rail II 32, and move to the cigarette supply working position 6 for the tobacco grading equipment to grab a single tobacco leaf; this cycle is repeated and alternating, and the tobacco grading equipment can be continuously supplied with cigarettes.

[0025] Of course, the start time of the servo motor II 31 can also be accurately controlled by calculating the relationship between the speed at which tobacco leaves in the cigarette supply box I 23 are grabbed and the time when the cigarette supply box II 33 moves to the working position 6, so that when the cigarette supply box I 23 exits the working position 6, the cigarette supply box II 33 arrives at the working position 6, thereby shortening the time difference between the replacement of the two cigarette supply boxes.

[0026] It should also be noted that the working order of the smoke supply box I 23 and the smoke supply box II 33 can be arbitrary, and the above discussion of the working order is only for the convenience of understanding and is not intended to limit it.
