[0020] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.
[0021] The embodiment of the present utility model: Figure 1-Figure 4 As shown, a tobacco shred air selection and screening device includes a fixed base plate 1, on which a tobacco shred air selection mechanism, a conveying mechanism 22 and a tobacco shred screening mechanism are provided. The conveying mechanism 22 is used to connect the tobacco shred air selection mechanism and the tobacco shred screening mechanism. The tobacco shred screening mechanism includes a support frame 2, a screening frame 4 and a driving mechanism. The support frame 2 is fixed on the fixed base plate 1, and two guide rods 3 are provided on the support frame 2. The two guide rods 3 are arranged opposite to each other and parallel to each other. The screening frame 4 is slidably connected to the two guide rods 3. There is a screen in the screening frame 4. The driving mechanism is arranged on the support frame 2, and the driving mechanism is used to drive the screening frame 4 to perform horizontal reciprocating motion.
[0022] Tobacco shreds are winnowed in the tobacco winnowing mechanism and then fall onto the conveyor mechanism 22, which delivers them to the screening frame 4. To prevent the tobacco shreds from falling from the discharge end of the conveyor mechanism 22 to the outside of the screening frame 4, a guide frame 25 is provided on the screening frame 4. The upper end of the guide frame 25 is located below the discharge end of the conveyor mechanism 22, allowing the tobacco shreds to pass through the guide frame 25 and fall into the screening frame 4. Driven by the drive mechanism, the screening frame 4 performs horizontal reciprocating motion, screening out impurities contained in the tobacco shreds to obtain clean tobacco shreds.
[0023] In a specific embodiment, the driving mechanism includes a motor frame 5 and a screening motor 24. The motor frame 5 is fixedly mounted on the support frame 2, and the screening motor 24 is mounted on one side wall of the motor frame 5. The output shaft of the screening motor 24 is vertically arranged upward, and the output shaft of the screening motor 24 is connected to a rotating rod 6. A drive shaft 7 is mounted on the top of the rotating rod 6. A clamping plate 8 is fixed on one side wall of the screening frame 4, and a clamping groove 26 is opened on the clamping plate 8. The drive shaft 7 is plugged into and slidably connected to the clamping groove 26.
[0024] The snap-fit groove 26 is a long strip-shaped groove, and the width of the snap-fit groove 26 is equal to the diameter of the drive shaft 7. When the screening motor 24 is working, it drives the rotating rod 6 to rotate, so that the drive shaft 7 can slide along the snap-fit groove on the snap-fit plate 8, so that the snap-fit plate 8 can drive the screening frame 4 to move. Through the continuous rotation of the screening motor 24, the screening frame 4 can continuously move back and forth to separate the tobacco shreds from impurities. This screening method does not require vibration, which is beneficial to reduce the noise generated during operation.
[0025] Furthermore, a fan bracket 27 is fixed on the fixed bottom plate 1 , a fan 10 is fixed on the fan bracket 27 , a cover 9 is installed on the top of the screening frame 4 , and the cover 9 is connected to the fan 10 through a plastic hose.
[0026] A tobacco collecting barrel 28 is also provided on the fixed bottom plate 1 . The air outlet end of the fan 10 is connected to the tobacco collecting barrel 28 through a hose. When the fan 10 is working, it can generate suction to suck the screened tobacco into the tobacco collecting barrel 28 .
[0027] Furthermore, the tobacco shred air selection mechanism includes a device frame 11, a separation box 12 and a screening box 19. The device frame 11 is fixed on the top of the fixed base plate 1, the separation box 12 is fixed on the device frame 11, and the top end of the screening box 19 is fixedly connected to the bottom end of the separation box 12, and the two are internally connected.
[0028] A drive motor 16 is mounted on one side wall of the separation box 12. The output end of the drive motor 16 is connected to a driving gear. A rotating shaft 13 is rotatably connected to the separation box 12. A plurality of separation rods 14 are provided on the rotating shaft 13. A driven gear 15 is mounted on one end of the rotating shaft 13. The driven gear 15 meshes with the driving gear. The separation rods 14 are made of aluminum alloy, which helps to reduce the weight of the separation rods 14.
[0029] When the tobacco shreds fall into the separation box 12, the driving motor 16 drives the driving gear to rotate, so that the driven gear 15 can drive the rotating shaft 13 to rotate, so that the separation rod 14 can continuously stir the falling tobacco shreds, and can separate the impurities attached to the tobacco shreds from the tobacco shreds, which is beneficial to the subsequent air separation.
[0030] A material box 17 is installed on the top of the separation box 12, and a set of opposite side walls of the material box 17 are movably mounted with inserts 18. The tobacco shreds are poured into the material box 17, and the amount of material falling can be controlled by controlling the distance between the two inserts 18.
[0031] A fan 23 is installed on one side wall of the screening box 19, and a collecting pipe 21 is provided on the side wall opposite to the fan 23. A material guide plate 20 is provided inside the screening box 19.
[0032] After stirring and separating, the tobacco shreds fall into the screening box 19, and the fan 23 blows air, so that the lighter tobacco shreds enter the collection box through the collection pipe 21. The guide plate 20 is helpful to prevent the tobacco shreds in the screening box 19 from flowing into too much at one time, resulting in poor air separation effect.
[0033] The working principle of the utility model is as follows: the tobacco shreds to be screened are poured into the material box 17, and the distance between the two inserting plates 18 is adjusted according to the demand to control the falling speed of the tobacco shreds. The tobacco shreds fall into the interior of the separation box 12. During the falling process, the driving motor 16 drives the active gear to rotate, so that the driven gear 15 can drive the rotating shaft 13 to rotate, so that the separation rod 14 can stir the falling tobacco shreds and separate the impurities attached to the tobacco shreds from the tobacco shreds. The tobacco shreds continue to fall through the guide plate 20 and are blown by the fan 23. , so that the lighter tobacco shreds are blown into the collection pipe 21 and then fall into the collection barrel. The remaining tobacco shreds fall onto the conveying mechanism 22 and are transported to the screening frame 4 through the conveying mechanism 22. The screening motor 24 drives the rotating rod 6 to rotate, so that the drive shaft 7 can slide along the clamping groove on the clamping plate 8, thereby driving the clamping plate 8 to move. The continuous rotation of the screening motor 24 allows the screening frame 4 to move back and forth, separating the tobacco shreds from impurities, and then the tobacco shreds are sucked into the tobacco collection barrel 28 through the fan 10.
[0034] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the scope of implementation of the present invention is not limited to what is shown in the drawings.
