[0039] like Figs. 1-3As shown, in this embodiment, the cigarette tobacco separation device includes a housing 1 and a clamping assembly. The housing 1 has a receiving cavity, with a receiving port 11 at the top and a discharging port 12 at the bottom. The receiving cavity includes a guide portion 13 with a gradually decreasing cross-sectional area, allowing tobacco entering from the receiving port 11 to slide through the guide portion 13 to the discharging port 12. The clamping assembly includes a rotating mechanism 2, a sleeve 3, and a locking member 4. The rotating mechanism 2 is rotatably mounted on the housing 1. The sleeve 3 is located within the receiving cavity and mounted on the rotating mechanism 2. The sleeve 3 is used to hold the cigarette 100. The locking member 4 is mounted on the sleeve 3 and used to fix the filter tip of the cigarette 100.
[0040] Specifically, the rotating mechanism 2 is driven by an electric motor, enabling it to rotate relative to the housing 1. The sleeve 3 is located above the receiving port 11 and is connected to one end of the rotating mechanism 2 located in the receiving cavity, serving to clamp the outer periphery of the cigarette 100. The locking member 4 is a fastening screw; rotating the locking member 4 secures the cigarette 100 within the sleeve 3. This design is suitable for cigarettes 100 of different sizes and those with irregularly shaped filters, satisfying the clamping and fixing of cigarettes 100 with filters of different shapes. The high-speed centrifugal force of the rotating mechanism 2 ejects the tobacco from the cigarette 100, effectively avoiding the damage to the filter caused by direct compressed air in traditional solutions, thus enabling the production of empty tubes of cigarettes 100 with undamaged irregularly shaped filters. The housing 1 is made of stainless steel or a material with sufficient strength, and its inner wall is smooth, with no dead corners, making it easy to clean. The lower part of the housing 1 is provided with a guide part 13, which has a trumpet-shaped structure. The two ends of the guide part 13 are a receiving port 11 and a discharging port 12, respectively. The receiving port 11 is a large end opening facing the cigarette 100 that is clamped and fixed, and the discharging port 12 is a small end opening located at the bottom of the housing 1. Under the guiding action of the guide part 13 and the wind force generated by the rotation of the sleeve 3, it is ensured that there are no tobacco shreds inside the housing 1, that is, all the separated tobacco shreds are discharged from the discharging port 12.
[0041] Furthermore, continue to refer to Figs. 1-3 The guide section 13 has a spiral structure. The inner circumference of the guide section 13 is configured as a funnel spiral. The receiving port 11 with a large end structure faces the sleeve 3 and the cigarette 100 held by the sleeve 3. The discharging port 12 with a small end structure serves as the discharging port for separated tobacco. Under the driving action of the rotating mechanism 2, the tobacco is thrown out from the empty tube, and the separated tobacco enters from the discharging port 12. It slides along the spiral structure from the receiving port 11 to the discharging port 12. At the same time, the wind force and airflow generated by the rotation of the sleeve 3 and the held cigarette 100 around the vertical axis of the rotating mechanism 2 can accelerate the tobacco to converge at the discharge port. Under the premise that the empty tube and the tobacco are completely separated, it is ensured that there is no tobacco inside the shell 1.
[0042] Furthermore, continue to refer to Figs. 1-3The clamping assembly also includes a flexible element 5 and a padding layer 6. The flexible element 5 is located inside the sleeve 3 and is connected to the locking element 4, serving to abut against the outer periphery of the cigarette 100's filter tip. The padding layer 6 is located on the inner periphery of the sleeve 3, allowing the cigarette 100 to be pressed tightly against the padding layer 6 under the action of the locking element 4. Both the flexible element 5 and the padding layer 6 are flexible pads made of rubber or leather with a rough, textured surface. The filter tip of the cigarette 100 is placed inside the sleeve 3, and the locking element 4 rotates relative to the sleeve 3 so that the end of the locking element 4 abuts against one side of the outer periphery of the cigarette 100's filter tip, while the other side of the outer periphery of the cigarette 100's filter tip abuts against the padding layer 6. This prevents damage to the internal structure of the irregularly shaped filter tip during clamping and provides a certain degree of protection.
[0043] Preferably, there are multiple locking elements 4, which are spaced apart along the length of the cigarette 100. By having multiple locking elements 4 simultaneously press the filter of the cigarette 100 against the inner circumference of the sleeve 3, the cigarette 100 can be fixed relative to the sleeve 3, which further improves the clamping and fixing of the cigarette 100 by the sleeve 3 and prevents the cigarette 100 from being thrown out during the swinging process.
[0044] Furthermore, continue to refer to Figs. 1-3The rotating mechanism 2 includes a drive motor 21 and a rotating component 22. The rotating component 22 is rotatably mounted on the housing 1, and the drive motor 21 is mounted on the housing 1 and drives the rotating component 22 to rotate. The drive motor 21 is fixed to the housing 1 by a connecting bracket or fixed to the base of the workbench by a connecting block. The output end of the drive motor 21 outputs power to the rotating component 22 via a transmission belt 23. The rotating component 22 includes a rotating part 221 and a connecting part 222. The rotating part 221 is rotatably mounted on the housing 1, and the connecting part 222 is connected to the rotating part 221. A connecting shaft 7 is rotatably connected to the connecting part 222, and the rotating part 221 is rotatably connected to the sleeve 3 via the connecting shaft 7. The rotating part 221 is configured as a rotating shaft, and the connecting part 222 is configured as a rotating arm. The rotating shaft has a stepped shaft structure and is fixedly connected to the connecting part 222 by a pin. The rotating component 22 is vertically mounted at the bottom center of the housing 1 via a bearing. The drive motor 21 outputs power to the rotating part 221 via the transmission belt 23. The connecting part 222 can rotate circumferentially with the rotating part 221 and can swing up and down within 3 degrees. When the drive motor 21 is not running, the sleeve 3 is in a natural vertical state. When the drive motor 21 starts, it drives the rotating part 221 to rotate, and the sleeve 3 rotates around the central axis of the rotating part 221, and can be parallel to the connecting part 222 at most, that is, the angle between the sleeve 3 and the connecting part 222 is in the range of 90 to 180 degrees. The drive motor 21 can adjust the power output through a frequency converter or reducer. The sleeve 3 is tilted relative to the connecting part 222 under the action of centrifugal force. The higher the speed of the drive motor 21, the larger the angle between the sleeve 3 and the connecting part 222, and the greater the force on the tobacco in the cigarette 100, which is conducive to throwing off the tobacco.
[0045] Furthermore, continue to refer to Figs. 1-3 There are multiple sockets 3, which are spaced apart along the rotation direction of the rotating mechanism 2. In this embodiment, there are two sockets 3, which are respectively disposed at both ends of the connecting part 222. The center of gravity of the connecting part 222 is located at the center of the rotating part 221, which can clamp and fix two cigarettes 100 at the same time, thus improving work efficiency.
[0046] Furthermore, continue to refer to Figs. 1-3 The cigarette tobacco separation device also includes an end cap 8, which is rotatably mounted on the housing 1 and used to open or close the opening of the housing 1. The end cap 8 is linked to the drive motor 21 through a centrifugal mechanical interlock device and a mechanical linkage brake. When the end cap 8 is opened, the drive motor 21 can be stopped and the rotating part 22 can be braked quickly. When the rotating part 22 is rotating at high speed, the end cap 8 cannot be opened.
[0047] Furthermore, continue to refer to Figs. 1-3The cigarette tobacco separation device also includes a weight detection mechanism 9, which comprises a weighing device 91 and a collection box 92. The weighing device 91 is located below the discharge port 12, and the collection box 92 is placed on the weighing device 91 and used to collect the tobacco. The separated tobacco falls into the collection box 92 through the discharge port 12. The weighing device 91 detects the weight of the tobacco and determines whether the tobacco is completely separated from the empty tube based on the known tobacco content of the cigarette 100. Optionally, after a longer separation time, it is assumed that the tobacco of the cigarette 100 is completely separated from the empty tube, and it is not necessary to determine the separation based on the weight of the tobacco.
[0048] The working principle of this cigarette tobacco separation device is as follows:
[0049] First, each cigarette 100 is weighed on the weight detection mechanism 9. Pairs of cigarettes 100 with a weight deviation of ±0.05g are selected for pairing. After selecting the required number of cigarettes 100, for slim cigarettes or cigarettes with a tighter burning end, a manual kneading process is performed to reduce the tightness. Next, the cigarette filter is inserted into the sleeve 3, and the locking member 4 is tightened, ensuring that the front and rear flexible members 5 and the padding layer 6 within the sleeve 3 firmly lock the cigarette filter. Then, the drive motor 21 rotates according to a set program, using an intermittent rotation mode. The acceleration during rotation increases the inertia of the cigarette 100, thereby improving the efficiency of tobacco detachment. During the empty tube manufacturing process, the weight detection mechanism 9 detects the weight of the tobacco falling from the discharge port 12 of the casing 1 to determine the degree of tobacco detachment inside the cigarette 100. Finally, after the tobacco has completely detached, the drive motor 21 gradually decelerates until the sleeve 3 is in a natural vertical position and then stops. The end cap 8 is opened, the residual tobacco powder inside the housing 1 is cleaned, and the produced empty cigarette tube 100 is taken out and its quality is checked. Empty tubes that do not meet the requirements are rejected. The above steps are repeated until the required number of empty cigarette tubes 100 are produced.
[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
