[0023] As Figure 1 and Figure 2 shown, an embodiment of the present application provides a measuring device for the discharge thickness of cut tobacco or tobacco leaves. The measuring device includes a frame body 5, a mounting part, an image acquisition device 11 and a first driving device 1.

[0024] A plurality of mutually parallel slide rails 14 are arranged on the periphery of the frame body 5. The slide rails 14 are used to set the installation part. The slide rails 14 can be cylindrical. The slide rails 14 can be arranged inside the frame body 5. When measuring the thickness of the cut tobacco or tobacco leaves by the measuring device, the frame body 5 is arranged above the conveying mechanism 2 for conveying the cut tobacco or tobacco leaves. The frame body 5 can be a rectangular frame. The slide rails 14 can be arranged at the three corners of the four corners inside the rectangular frame. Exemplarily, the frame body 5 can be a gantry, and the gantry straddles both sides of the conveying mechanism 2. Of course, the frame body 5 can also be of other structures, as long as the frame body 5 can ensure that the image acquisition device 11 is located above the conveying mechanism 2. In this application, the conveying mechanism 2 can be a conveyor belt. The conveying mechanism 2 can be a part of the measuring device. At this time, the measuring device can be connected to the production line to realize the measurement of the thickness. Of course, the conveying mechanism 2 can also not be a part of the measuring device. At this time, the measuring device can be directly installed on the original conveyor belt of the production line. In some embodiments, the conveying mechanism 2 can include a plurality of support feet 6, and the plurality of support feet 6 can realize the stable support of the conveying mechanism 2. The installation part is slidably connected to the plurality of slide rails 14. When the installation part slides along the slide rails 14, the distance from the conveying mechanism 2 can be changed; the image acquisition device 11 is arranged on the installation part. The image acquisition device 11 is used to acquire the images of the cut tobacco or tobacco leaves on the conveying mechanism 2. Exemplarily, the image acquisition device 11 can be a camera. The number of the image acquisition devices 11 can be one or more. The image acquisition device 11 is communicatively connected to the processor for calculating the discharge thickness. The installation part is used to install the image acquisition device 11. The installation part realizes adjustable position through the slide rails 14. When the position of the installation part changes, it can drive the image acquisition device 11 mounted thereon to move together, so as to facilitate the image acquisition device 11 to obtain the images for calculating the material thickness. After the image acquisition device 11 obtains the images of the cut tobacco or tobacco leaves, the images are transmitted to the processor for processing. The processor uses the AI artificial intelligence deep learning algorithm to perform 3D stereoscopic imaging on the cut tobacco and tobacco leaves during transmission and then calculates the thickness, so as to accurately measure the transmitted thickness and then accurately control the conveying amount. The processor can be the processor of an external terminal system.

[0025] The first driving device 1 is arranged on the frame body 5. The output end of the first driving device 1 is in transmission connection with a screw rod 10. The screw rod 10 is arranged parallel to the slide rail 14. A threaded hole that is in threaded cooperation with the screw rod 10 is arranged on the installation part. The first driving device 1 can drive the screw rod 10 to rotate to drive the installation part to slide along the slide rail 14. In this embodiment, the first driving device 1 can be a driving motor. The screw rod 10 can be directly installed on the output shaft of the first driving device 1, or can be in transmission connection with the first driving device 1 through other transmission mechanisms (such as gears, belts, chains, etc.). In this embodiment, the screw rod 10 is arranged parallel to the slide rail 14. In this way, when the first driving device 1 drives the screw rod 10 to rotate, the screw rod 10 converts the rotational motion into a linear motion of the installation part through the threaded hole, thereby driving the installation part to slide on the slide rail 14.

[0026] The measuring device for the discharging thickness of cut tobacco or tobacco leaves provided by the embodiment of the present application collects images of cut tobacco or tobacco leaves on the conveying mechanism 2 through an image acquisition device 11 installed on an installation part whose distance from the conveying mechanism 2 is adjustable. After the image acquisition device 11 transmits the images to the processor, the AI artificial intelligence deep learning algorithm is used to perform 3D stereoscopic imaging on the cut tobacco or tobacco leaves during transmission and then calculate the thickness, so as to obtain the discharging thickness. Combining with the material density, the material flow rate can be obtained, so as to facilitate the precise control of the material flow rate.

[0027] Combined with Figure 2 and Figure 3 In some embodiments, the installation part includes an installation part body and slip rings 12 corresponding to the number of slide rails 14. The image acquisition device 11 can be arranged on the installation part body. The slip rings 12 are slidably connected to the slide rails 14. The installation part further includes a transmission ring. A threaded hole is formed on the transmission ring. Each slip ring 12 and the transmission ring are respectively connected to the installation part body through a connecting piece 13. The extending direction of the connecting piece 13 is the same as that of the slide rail 14. In this embodiment, the slip rings 12 can have a similar structure to the transmission ring. The difference may only be that the transmission ring is provided with a threaded hole with internal threads that can cooperate with the screw rod 10, while the slip rings 12 are provided with holes with smooth inner walls that cooperate with the slide rails 14. By providing the connecting piece 13 extending along the slide rail 14, it is convenient to control the height of the image acquisition device 11.

[0028] In some embodiments, the number of slide rails 14 is three, and the three slide rails 14 are distributed in a rectangular shape with the screw rod 10; the number of slip rings 12 is three, and the three slip rings 12 are distributed in a rectangular shape with the transmission ring. In this embodiment, the three slide rails 14 and the screw rod 10 can form a stable rectangular four-corner support structure. The slip rings 12 and the transmission ring are respectively located at the four vertices of the rectangle, so that the sliding of the installation part is more stable.

[0029] Combined with Figure 1 and Figure 2, in some embodiments, the measuring device further includes a stirring mechanism. The stirring mechanism is disposed on the frame body 5 and, along the conveying direction of the conveying mechanism 2, is disposed in front of the image acquisition device 11. The stirring mechanism is used for stirring the cut tobacco or tobacco leaves flowing through the stirring mechanism. It can be understood that in the actual production process, the cut tobacco and tobacco leaves are usually stacked and conveyed randomly. Since the algorithm for calculating the thickness is fixed, the uneven shapes and heights of the cut tobacco and tobacco leaf materials may cause errors. Therefore, in this embodiment, the stirring mechanism is used to stir and flatten the uneven cut tobacco or tobacco leaves that are about to pass through the image acquisition device 11, so as to make the material distribution more stable during the entire conveying process, and the stacking of the cut tobacco and tobacco leaves more uniform, providing convenience for the later imaging algorithm calculation and reducing the occurrence of special situations.

[0030] In some embodiments, the stirring mechanism includes a second driving device 3, a transmission rod 7, and a stirring assembly 8. The second driving device 3 is disposed on the frame body 5; the transmission rod 7 is drivingly connected to the output end of the second driving device 3; the stirring assembly 8 is drivingly connected to the transmission rod 7. The transmission rod 7 can transmit the power output by the second driving device 3 to the stirring assembly 8, and the stirring assembly 8 is used for stirring the cut tobacco or tobacco leaves flowing through the stirring assembly 8. In this embodiment, the second driving device 3 can be a motor. By providing the transmission rod 7, the driving force of the second driving device 3 installed at a higher position can be transmitted to the stirring assembly 8 at a lower position.

[0031] As Figure 4 shown, in some embodiments, the stirring assembly 8 includes a mounting seat, a driving gear 802, a driven gear 801, and a stirring member 9. The mounting seat is connected to the outer shell 804 of the transmission rod 7. The driving gear 802 and the driven gear 801 are disposed on the mounting seat. The driving gear 802 is drivingly connected to the second driving device 3 through the transmission rod 7. The driven gear 801 meshes with the driving gear 802. The stirring member 9 is connected to the central position of the driven gear 801. In this embodiment, the transmission rod 7 may have a hollow outer shell 804. A transmission shaft is disposed in the outer shell 804. The outer shell 804 can be connected to the mounting seat to fix the mounting seat. The driving gear 802 and the driven gear 801 are disposed inside the mounting seat. The driving gear 802 is connected to the transmission shaft in the transmission rod 7 and is thus driven by the transmission shaft. The driven gear 801 meshes with the driving gear 802. The stirring member 9 is disposed on the driven gear 801. The stirring member 9 can rotate as the driven gear 801 rotates, thereby realizing the stirring of the cut tobacco or tobacco leaves. A central shaft 803 may be disposed at the center of the driven gear 801, and one end of the central shaft 803 extends out to be fixedly connected to the stirring member 9 respectively.

[0032] In some embodiments, the number of driven gears 801 is plural. The driven gears 801 are circumferentially distributed along the driving gear 802 and mesh with the driving gear 802. A stirring member 9 is mounted on each driven gear 801. In this embodiment, the driving gear 802 drives the plural driven gears 801 to rotate, thereby driving the plural stirring members 9 to rotate. The plural stirring members 9 can stir the cut tobacco or tobacco leaves at different positions, so that the distribution of the material is more uniform.

[0033] In some embodiments, the number of the stirring members 9 is three. The three stirring members 9 are distributed in an equilateral triangle, and the rotation centers of the three stirring members 9 can be used as the three vertices of the triangle.

[0034] In some embodiments, the stirring mechanism further includes an "L"-shaped fixing plate 4. The fixing plate 4 is arranged on the frame body 5, and the second driving device 3 is mounted on the frame body 5 through the fixing plate 4.

[0035] Working principle: When using the measuring device for the discharging thickness of cut tobacco or tobacco leaves provided in the embodiment of the present application, the cut tobacco and tobacco leaves can be conveyed by the conveying mechanism 2. During the conveying process, the cut tobacco and tobacco leaves during the conveying process can be photographed by the image acquisition device 11, and then the image is formed and the data is transmitted to the terminal control system. The AI artificial intelligence deep learning algorithm is used to perform 3D stereoscopic imaging on the cut tobacco and tobacco leaves during transmission and then calculate the thickness, so as to accurately measure the transmission thickness and then accurately control the conveying amount.
