DETAILED DESCRIPTION

[0019] The embodiments of the present invention are described in detail below, and 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 only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0020] Embodiments of the present utility model: Figure 1-Figure 5 As shown, a device for uniformly flavoring laboratory tobacco shreds, comprising a material box 1, one end of the material box 1 is connected to a hopper 2, the end of the material box 1 connected to the hopper 2 is provided with a liftable tobacco shred baffle 3, the feeding end of a screw elevator 4 is connected to the hopper 2, the discharging end of the screw elevator 4 is connected to the tobacco shred flavoring device, the bottom of the tobacco shred flavoring device is provided with a first discharging pipe 5 and a second discharging pipe 6, the first discharging pipe 5 is connected to the hopper 2 through a tobacco shred conveyor belt 7.

[0021] The height of the material box 1 is higher than that of the hopper 2. The tobacco baffle 3 in the material box 1 is used to block the tobacco, so that the tobacco in the hopper 2 can be put into the material box 1 when adding flavor. The two waves of tobacco can be distinguished by the setting of the tobacco baffle 3. The tobacco in the hopper 2 can be lifted to the tobacco flavoring device by the screw elevator 4. The tobacco is flavored in the tobacco flavoring device. After flavoring, it falls onto the tobacco conveyor belt 7 through the first discharge pipe 5 and returns to the hopper 2 through the tobacco conveyor belt 7. When the flavoring liquid in the tobacco flavoring device is completely used up, the tobacco is finally flavored and sent to the tobacco storage barrel 22 for storage through the second discharge pipe 6.

[0022] In a specific embodiment, an inclined partition 8 is provided in the material box 1, and the height of the partition 8 gradually increases from one end in contact with the tobacco baffle 3 to the other end. The internal space of the material box 1 is divided into an upper space and a lower space by the partition 8, and a tobacco baffle driving device is provided in the lower space.

[0023] There is a gap between the lower end of the partition 8 and the hopper 2, through which the tobacco baffle 3 passes. The lower end of the partition 8 is flush with the top of the hopper 2. The partition 8 can make the tobacco stored in the material box 1 automatically slide into the hopper 2 on the one hand, and on the other hand, it can divide the internal space of the material box 1, making it convenient to place the tobacco baffle driving device below.

[0024] Furthermore, a slide groove 9 extending in the vertical direction is opened on the inner wall of the material box 1, and the two ends of the tobacco baffle 3 are plugged into and slidably connected with the slide groove 9. A rack 10 is embedded in the middle position of the side of the tobacco baffle 3 facing the partition 8. The tobacco baffle driving device includes a first stepper motor 11 and a driving gear 12. The first stepper motor 11 is defined in the lower space by a motor bracket 13, and the driving gear 12 is fixedly mounted on the output shaft of the first stepper motor 11, and the driving gear 12 is meshed with the rack 10.

[0025] The first stepper motor 11 drives the driving gear 12 to rotate, and the driving gear 12 cooperates with the rack 10 to move the rack 10, thereby realizing the height adjustment of the tobacco baffle 3. In this embodiment, preferably, an inclined guide plate 21 is fixed on the top of the tobacco baffle 3. The guide plate 21 is used to cover the gap between the material box 1 and the hopper 2, so that after the tobacco baffle 3 is completely received in the material box 1, the guide plate 21 connects the partition 8 and the top edge of the hopper 2 to prevent the tobacco from falling into the material box 1.

[0026] Furthermore, the inner wall of the hopper 2 is a funnel-shaped structure, one end of the tobacco conveyor belt 7 is fixedly connected to the top of the hopper 2 , and one end of the screw elevator 4 passes through the side wall of one side of the hopper 2 and extends to the bottom of the hopper 2 .

[0027] Designing the inner wall of the hopper 2 as a funnel-shaped structure allows the tobacco to automatically slide to the center of the hopper 2, and then enter the feed port of the screw elevator 4. The screw elevator 4 and the tobacco conveyor belt 7 are commercially available products that can be purchased directly, so the specific structure and working principle of the screw elevator 4 and the tobacco conveyor belt 7 are not described in detail in this embodiment.

[0028] Furthermore, the discharge end of the screw elevator 4 is vertically arranged downward, and the tobacco flavoring device is connected to include a flavoring cylinder 14, an atomizing nozzle 15 and an essence and fragrance storage tank 16. The flavoring cylinder 14 is arranged vertically, and the upper end of the flavoring cylinder 14 is fixedly connected to the discharge end of the screw elevator 4. The essence and fragrance storage tank 16 is fixedly arranged on the top of the flavoring cylinder 14. Two atomizing nozzles 15 are fixedly arranged on the side wall of the flavoring cylinder 14. The two atomizing nozzles 15 are symmetrically arranged relative to the axis of the flavoring cylinder 14. The essence and fragrance storage tank 16 is connected to the feed end of the two atomizing nozzles 15 through a connecting pipe, and a liquid level sensor (not shown in the figure) is arranged in the essence and fragrance storage tank 16. A photoelectric switch 20 is provided at the discharge end of the screw elevator 4.

[0029] The photoelectric switch 20 is used to sense whether tobacco shreds have fallen. When tobacco shreds have fallen, the atomizing nozzle 15 sprays the flavor and fragrance liquid to prevent the flavor and fragrance liquid from being wasted. High-pressure gas is continuously introduced into the aroma cylinder 14. The atomizing nozzle 15 is provided with a solenoid valve. The high-pressure gas pressurizes the flavor and fragrance liquid. When the solenoid valve on the atomizing nozzle 15 is opened, the flavor and fragrance liquid is sprayed out in a mist form through the atomizing nozzle 15.

[0030] Furthermore, the first discharge pipe 5 and the second discharge pipe 6 are arranged opposite to the connecting port of the flavoring cylinder 14, a reversing baffle 17 is provided at the bottom of the flavoring cylinder 14, a support plate 18 is fixedly provided between the first discharge pipe 5 and the second discharge pipe 6, a second stepper motor 19 is fixedly provided on the support plate 18, and the output shaft of the second stepper motor 19 passes through the side wall of the flavoring cylinder 14 and is fixedly connected to the reversing baffle 17.

[0031] The working principle of the utility model is as follows: when working, the first stepper motor 11 works, and the tobacco baffle 3 is lowered by driving the gear 12 and the rack 10, until the guide plate 21 contacts the partition 8 and the top surface of the hopper 2. The tobacco in the material box 1 slides along the partition 8 into the hopper 2. After a preset time, the first stepper motor 11 rotates in the opposite direction, so that the tobacco baffle 3 rises to the original position. At this time, the staff can load the tobacco that needs to be flavored next time into the material box 1.

[0032] The tobacco shreds falling into the hopper 2 slide along the inner wall to the center position of its bottom, and the tobacco shreds in the hopper 2 are continuously lifted into the flavoring cylinder 14 by the screw elevator 4. When the tobacco shreds pass through the photoelectric switch 20, the solenoid valves on the two atomizing nozzles 15 are controlled to open, and the flavors and fragrances are sprayed out in the form of mist through the two atomizing nozzles 15 and evenly sprayed on the tobacco shreds. It should be noted here that the liquid level sensor detects the liquid in the flavor and fragrance storage tank 16 in real time. Before the liquid is exhausted, the reversing baffle 17 always blocks the second discharge pipe 6, and the first discharge pipe 5 is in an open state. The tobacco shreds fall onto the tobacco conveyor belt 7 through the first discharge pipe 5 and are The conveyor belt 7 returns to the hopper 2 until the liquid level sensor detects that the flavor and fragrance are completely consumed, so that the second stepper motor 19 rotates, driving the reversing baffle 17 to rotate a certain angle, so that the reversing baffle 17 blocks the first discharge pipe 5, opens the second discharge pipe 6, and the tobacco that passes through the flavoring cylinder 14 again falls into the tobacco storage barrel 22 through the second discharge pipe 6. When the photoelectric switch 20 cannot detect the tobacco and the liquid level sensor cannot detect the liquid, the reversing baffle 17 is closed by the second stepper motor 19, and the first discharge pipe 5 is opened. At the same time, the first stepper motor 11 is controlled to work, so that the tobacco baffle 3 descends and enters the next working cycle. The working state of each component in the utility model is controlled by a PLC programmable controller.

[0033] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
