[0002] The filling value of cut tobacco is one of the important parameters of cigarettes. It can reflect the quality of cigarettes. People can understand the aroma and taste degree of cigarettes from it. At the same time, quality control can also be carried out for a certain mixture of tobacco leaves to ensure that the quality of each produced cigarette is consistent.

[0003] In addition, controlling the filling value of cut tobacco will also affect the tar release amount of cigarettes. When the filling value of cut tobacco exceeds a certain proportion, the tar release amount will increase significantly, generating a large amount of carcinogens. Therefore, in the process of measuring the filling value of cut tobacco, it is generally required not to exceed a certain proportion to ensure the health of consumers.

[0035] In addition, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that the examples can be practiced without these specific details.

[0036] The determination of the tobacco filling value is carried out by measuring the density of the tobacco cut filler under a preset pressure, so as to know the filling degree of the tobacco cut filler. During the detection process of the tobacco filling degree, since the tobacco cut filler needs to be extruded, it will affect the detection of the tobacco cut filler during the loading process of the tobacco cut filler, resulting in a decrease in the detection efficiency.

[0037] Based on this, an embodiment of this specification proposes a multi-station tobacco filling degree detection device: as Figures 1 to 8 shown, it includes a bottom plate 1, a rotating frame 2, a cartridge 3 and a driving member. The cartridge 3 is connected to the rotating frame 2. There are three or more cartridges 3. The driving member is used to drive the rotating frame 2 to rotate. The rotating frame 2 can drive the cartridge 3 to rotate. One end of the cartridge 3 is close to the bottom plate 1, and the distance between the cartridge 3 and the bottom plate 1 is 0 - 0.5 mm, which can prevent the tobacco cut filler from scattering out from the gap between the cartridge 3 and the bottom plate 1 during the rotation process.

[0038] The bottom plate 1 is provided with a feeding position 4, a pressing position 5 and a discharging position 6. Each cartridge 3 can be respectively rotated to the feeding position 4, the pressing position 5 and the discharging position 6. The discharging position 6 is a discharging hole, and the diameter of the discharging hole corresponds to that of the cartridge 3. The bottom plate 1 is connected with a pressing mechanism, and the pressing mechanism is used to extrude the tobacco cut filler in the cartridge 3 at the pressing position 5.

[0039] Add a specific mass of tobacco cut filler to the cartridge 3 at the feeding position 4. The rotating frame 2 drives the cartridge 3 to move to the pressing position 5. The pressing mechanism extrudes the tobacco cut filler in the cartridge 3. When the preset pressure value is reached, the pressing mechanism stops extruding, calculates the volume of the tobacco cut filler in the cartridge 3, so as to obtain the density of the tobacco cut filler under the predetermined pressure condition, and thus know the filling degree of the tobacco cut filler. After the extrusion is completed, the rotating frame 2 drives the cartridge 3 to rotate to the discharging position, and the tobacco cut filler drops through the discharging position and leaves the device. The whole process sets the feeding, extrusion and discharging at three different positions respectively, improving the detection efficiency.

[0040] In the technical solution of this application, setting three cartridges 3 corresponding to the feeding position 4, the pressing position 5 and the discharging position 6 is the basic setting. More cartridges 3 and feeding positions 4, pressing positions 5 and discharging positions 6 can be set to meet the efficiency requirements, and the effects and working processes described in the embodiments of this application are the same, which will not be elaborated one by one here.

[0041] As Figure 3As shown in the figure, the pressing mechanism includes a first lifting member, which is connected to a pressing head 8. The pressing head 8 is cylindrical and is adapted to the material cylinder 3. The pressing head 8 can be placed in the material cylinder 3. The pressing head 8 is connected to a pressure sensor 30, and the pressure sensor 30 is arranged between the pressing head 8 and the first lifting member. The pressure sensor 30 is set with a preset pressure.

[0042] As Figure 3 shown in the figure, the first lifting member includes a lifting motor 9, a lead screw 10 and a lifting bracket 11. The lead screw 10 is rotatably connected to the lifting bracket 11. The lifting motor 9 drives the lead screw 10 to rotate. The lead screw 10 is connected to a connecting head 12, and the connecting head 12 is slidably connected to the lifting bracket 11. The pressure sensor 30 is connected to the connecting head 12, and the pressure sensor 30 is arranged between the pressing head 8 and the connecting head 12. The pressure sensor 30 is electrically connected to the lifting motor 9. The lead screw 10 is connected to an encoder 27 through a belt. The encoder 27 obtains the moving distance of the pressing head 8 by detecting the number of turns of the lead screw 10 rotating, and then knows the compression volume under the set pressure.

[0043] When the pressure sensor 30 detects the preset pressure, the pressing head 8 stops moving, and the volume of the cut tobacco at this time is calculated, so as to obtain the density of the cut tobacco under the preset pressure. The pressure sensor 30 is arranged at the position between the pressing head 8 and the connecting head 12, which can reduce the interference to the cut tobacco during the moving process and improve the detection accuracy and efficiency.

[0044] As Figure 3 and 4 shown in the figure, the material cylinder 3 is connected to the rotating frame 2 through a fixing ring 13. The driving member includes a driving motor 14, and the driving motor 14 drives the rotating frame 2 to rotate through a belt.

[0045] As Figure 6 shown in the figure, the bottom plate 1 is provided with a weighing platform 15. The weighing platform 15 is connected to a hopper 7. The hopper 7 is arranged above the feeding position 4. The hopper 7 is rotatably connected to a baffle 16. The baffle 16 is connected to the hopper 7 through a spring 17. The weighing platform 15 is connected to a baffle motor 18. The baffle motor 18 is connected to a push rod 19. One end of the push rod 19 away from the baffle motor 18 is arranged on the side of the baffle 16 facing the spring 17. The baffle motor 18 drives the opening and closing of the baffle 16 through the push rod 19.

[0046] Under the action of the spring 17, the baffle 16 abuts against the hopper 7, and the cut tobacco falls into the hopper 7. The weighing platform 15 weighs the cut tobacco. After the weighing is completed, the baffle motor 18 drives the push rod 19 to rotate in the direction away from the hopper 7, so that the baffle 16 is separated from the hopper 7, and the cut tobacco leaves the hopper 7. The baffle motor 18 drives the push rod 19 to move towards the hopper 7, and the baffle 16 abuts against the hopper 7 again under the pulling force of the spring 17, which is convenient for weighing.

[0047] There are four barrel bodies 3 provided, and the bottom plate 1 is further provided with an adjustment position 20. The feeding position 4, the pressing position 5, the discharging position 6 and the adjustment position 20 are evenly arranged. After the barrel body 3 filled with cut tobacco moves to the adjustment position 20, the cut tobacco in the barrel body 3 can be leveled. The feeding position 4, the adjustment position 20, the pressing position 5 and the discharging position 6 are arranged in sequence along the rotation direction of the barrel body 3. At the adjustment position 20, the cut tobacco in the barrel body 3 can be leveled mechanically or manually, so as to avoid errors caused by inaccurate pressure detection due to uneven cut tobacco in the barrel body 3 and improve the accuracy of detection. At the discharging position 6, the cut tobacco in the barrel body 3 can be knocked down mechanically or manually to prevent the cut tobacco from getting stuck in the barrel body 3. As Figure 1 shown, it can be discharged by the automatic material knocking method of the material discharging part 29, and the material discharging part 29 can be a cylinder or an electric cylinder.

[0048] A bearing plate 28 is fixedly connected to the bottom plate 1. Specifically, as Figure 8 shown, the adjustment position 20, the feeding position 4, the pressing position 5 and the discharging position 6 are all arranged on the bearing plate 28. The rotating frame 2 passes through the bearing plate 28 and is rotatably connected to the bearing plate 28.

[0049] As Figure 4 shown, the bottom plate 1 is connected with a first position sensor 21 and a second position sensor 22. When the first position sensor 21 detects the barrel body 3, the rotating frame 2 moves at a reduced speed. When the second position sensor 22 detects the barrel body 3, the rotating frame 2 stops moving. The rotating frame 2 decelerates in segments until it stops, which improves the service life of the driving motor 14, the stability of the system, and the accuracy of the movement of the barrel body 3.

[0050] As Figure 1 and Figure 7 shown, the bottom plate 1 is provided with a leveling mechanism. The leveling mechanism includes a second lifting member. The second lifting member is connected with a leveling motor 24 through a connecting plate 23. The connecting plate 23 is rotatably connected with a rotating shaft 25. The leveling motor 24 and the rotating shaft 25 are connected by a belt. The rotating shaft 25 is connected with a stirring rod 26. The leveling motor 24 and the stirring rod 26 are located on one side of the connecting plate 23 close to the barrel body 3.

[0051] The second lifting member drives the stirring rod 26 to move into the barrel body 3 at the adjustment position. The leveling motor 24 drives the stirring rod 26 to rotate through the rotating shaft 25 and the belt, so as to stir and level the cut tobacco, and avoid errors in detection caused by uneven cut tobacco.

[0052] In this specification, the same or similar parts among the various embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments. In particular, for the embodiments described later, the description is relatively simple, and the relevant parts can be referred to the partial description of the foregoing embodiments.

[0053] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in the present application should be covered by the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
