[0032] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.
[0033] In all the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.
[0034] like Figures 1 to 3 As shown, this utility model embodiment provides a stem-and-filament separation device, including: a main body 1, a discharge hopper 2, a detection component 3, a cleaning component 4, and a control component 5.
[0035] A tobacco stem recycling box 6 is provided on the rear side of the main body 1, and a discharge hopper 2 is provided above the tobacco stem recycling box 6, with the discharge port of the discharge hopper 2 facing the tobacco stem recycling box 6.
[0036] The detection component 3 includes a first camera 31, a second camera 32 and a third camera 33 disposed on the side wall of the main body 1. The first camera 31, the second camera 32 and the third camera 33 are evenly spaced between the discharge hopper 2 and the tobacco stem recycling box 6.
[0037] Specifically, the first camera 31, the second camera 32, and the third camera 33 are arranged sequentially from the discharge hopper 2 toward the tobacco stem recycling box 6.
[0038] Cleaning component 4 is used to clean debris from the first camera 31, the second camera 32 and the third camera 33.
[0039] The control component 5 is electrically connected to the detection component 3 and the cleaning component 4.
[0040] Specifically, the first camera 31, the second camera 32, and the third camera 33 are used to capture images of the falling tobacco stems and transmit the images to the control component 5. The control component 5 stores normal images of the tobacco stems falling from the discharge hopper 2 into the tobacco stem recycling box 6. When the control component 5 receives images transmitted by the first camera 31, the second camera 32, and the third camera 33, it compares the images transmitted by the first camera 31, the second camera 32, and the third camera 33 with the normal images. When the amount of tobacco fibers in the images transmitted by the first camera 31, the second camera 32, and the third camera 33 is greater than the amount of tobacco fibers in the normal images, the control component 5 stops the equipment from working and alerts the operator, allowing the operator to promptly detect abnormalities in the separation of tobacco fibers.
[0041] It should be noted that the methods used to process the images are conventional techniques and will not be described here.
[0042] This invention places the discharge hopper 2 above the tobacco stem collection box 6, with the discharge port of the discharge hopper 2 facing the tobacco stem collection box 6; and evenly spaced the first camera 31, the second camera 32, and the third camera 33 between the discharge hopper 2 and the tobacco stem collection box 6. During operation, the discharge hopper 2 transports tobacco stems to the tobacco stem collection box 6. The first camera 31, the second camera 32, and the third camera 33 sequentially capture images of the falling tobacco stems and transmit the captured images to the control component 5. The control component 5 analyzes the images, and if the tobacco content is too high, the control device stops working and alerts the operator, allowing the operator to promptly detect abnormalities in stem-to-tobacco separation, stabilize cigarette quality, and reduce tobacco consumption. Furthermore, the cleaning component 4 cleans impurities from the first camera 31, the second camera 32, and the third camera 33, improving the accuracy of detection.
[0043] In one embodiment of the stem-fiber separation device of this utility model, such as Figure 2 As shown, the detection component 3 also includes a fixing plate 34 and three connecting rods 35. The fixing plate 34 is disposed on the side wall of the main body 1, and the three connecting rods 35 are evenly spaced on the fixing plate 34. The three connecting rods 35 are respectively connected to the first camera 31, the second camera 32 and the third camera 33.
[0044] This utility model provides a fixing function for the first camera 31, the second camera 32, and the third camera 33 by evenly arranging three connecting rods 35 on the fixing plate 34 and connecting the three connecting rods 35 to the first camera 31, the second camera 32, and the third camera 33 respectively, thereby increasing the stability of the installation.
[0045] Furthermore, in order to make the photos of the tobacco stem taken by the first camera 31, the second camera 32 and the third camera 33 more accurate, the angle between the connecting rod 35 and the first camera 31, the second camera 32 and the third camera 33 is set to 100 degrees-160 degrees.
[0046] Specifically, the angle between the connecting rod 35 and the first camera 31, the second camera 32 and the third camera 33 is 120 degrees.
[0047] In one embodiment of the stem-fiber separation device of this utility model, such as Figure 1 and Figure 2 As shown, the fixing plate 34 is rotatably connected to the side wall of the body 1.
[0048] The detection component 3 also includes a support plate 36 and a first drive motor 37. The support plate 36 is disposed on the side wall of the main body 1 and located below the fixed plate 34. The first drive motor 37 is disposed on the support plate 36, and the output shaft of the first drive motor 37 is connected to the fixed plate 34.
[0049] Specifically, the first drive motor 37 is also electrically connected to the control component 5. The operator can control the first drive motor 37 to rotate forward or backward through the control component 5, thereby controlling the support plate 36 to rotate to the left or right, thereby adjusting the angles of the first camera 31, the second camera 32 and the third camera 33, and further improving the shooting effect and accuracy.
[0050] In one embodiment of the stem-fiber separation device of this utility model, such as Figure 2 As shown, a mounting groove 7 is provided on the side wall of the main body 1.
[0051] The detection component 3 also includes a rotating shaft, which is set in the mounting groove 7, passes through the fixing plate 34, and its two ends are rotatably connected to the side wall of the mounting groove 7.
[0052] Specifically, the width of the mounting groove 7 is greater than the width of the fixing plate 34. This utility model enables the fixing plate 34 to rotate stably by having the rotating shaft pass through the fixing plate 34 and rotatably connecting the two ends of the rotating shaft to the side wall of the mounting groove 7.
[0053] In one embodiment of the stem-fiber separation device of this utility model, such as Figure 2 As shown, the cleaning component 4 includes a nozzle 41, an electric telescopic rod 42, and a connecting pipe. The electric telescopic rod 42 is mounted on the main body 1 and located above the tobacco stem recycling box 6. The electric telescopic rod 42 is connected to the nozzle 41. The connecting pipe is located inside the electric telescopic rod 42. The first end of the connecting pipe is connected to the nozzle 41, and the second end of the connecting pipe is connected to an external air source.
[0054] Specifically, during the cleaning process, the electric telescopic rod 42 drives the nozzle 41 to retract close to the side wall of the main body 1, minimizing the impact on the falling of the tobacco stems.
[0055] When dust, tobacco stems, tobacco shreds, or other debris are present on the first camera 31, the second camera 32, and the third camera 33, the control component 5 analyzes the images transmitted by the first camera 31, the second camera 32, and the third camera 33 respectively and can determine that impurities exist on the first camera 31, the second camera 32, and the third camera 33, or the operator can clearly determine the presence of impurities from the images transmitted by the first camera 31, the second camera 32, and the third camera 33. At this time, the electric telescopic rod 42 extends, driving the nozzle 41 to move, and introducing gas from the external air source into the connecting pipe, so that the nozzle 41 blows on the first camera 31, the second camera 32, and the third camera 33, thereby cleaning the impurities on the first camera 31, the second camera 32, and the third camera 33, which can effectively ensure the accuracy of detection.
[0056] In one embodiment of the stem-separation device of this utility model, the electric telescopic rod 42 is rotatably connected to the body 1.
[0057] The cleaning component 4 also includes a second drive motor, which is located inside the main body 1, and the output end of the second drive motor is connected to the electric telescopic rod 42.
[0058] In this embodiment, there is only one nozzle 41 and one electric telescopic rod 42, which are horizontally arranged with the second camera 32. By placing the second drive motor inside the main body 1 and connecting the output end of the second drive motor to the electric telescopic rod 42, the second drive motor drives the electric telescopic rod 42 to rotate, thereby causing the nozzle 41 to rotate. This allows the nozzle 41 to perform purging treatment on the first camera 31, the second camera 32, and the third camera 33, effectively saving costs.
[0059] In another embodiment, there may be two nozzles 41, two electric telescopic rods 42, and two electric drive motors. The two nozzles 41 and the two electric telescopic rods 42 are respectively arranged between the first camera 31 and the second camera 32, and between the second camera 32 and the third camera 33. The two nozzles 41 and the two electric telescopic rods 42 are driven to rotate by the second drive motor, thereby realizing the blowing treatment of the first camera 31, the second camera 32 and the third camera 33.
[0060] In another embodiment, there may be three nozzles 41, three electric telescopic rods 42, and three second drive motors. The three nozzles 41 and the three electric telescopic rods 42 are respectively arranged horizontally with the first camera 31, the second camera 32, and the third camera 33, so that the three nozzles 41 respectively blow and clean the first camera 31, the second camera 32, and the third camera 33, thereby further improving the cleaning effect.
[0061] In one embodiment of the stem-fiber separation device of this utility model, such as Figure 1 and Figure 3 As shown, the control component 5 includes a controller 52 and a display screen 51. The display screen 51 is located at the end of the main body 1. The controller 52 is electrically connected to the display screen 51, the first camera 31, the second camera 32, the third camera 33, the detection component 3, and the cleaning component 4.
[0062] Specifically, the display screen 51 is used to display images captured by the first camera 31, the second camera 32 and the third camera 33, and the controller 52 can control the operation of the second drive motor, the electric telescopic rod 42 and the first drive motor 37.
[0063] In one embodiment of the stem-fiber separation device of this utility model, such as Figure 1 and Figure 3 As shown, the control component 5 also includes an alarm 53, which is located on the top of the main body 1 and is electrically connected to the controller 52.
