[0002] The blending of tobacco and stems is a crucial step in cigarette production, and the precision of this blending significantly impacts the quality of the finished cigarettes. During the blending process, it is essential to ensure that the tobacco and stems are evenly and continuously distributed onto the conveyor belt that carries the mixture, thereby guaranteeing the flavor of the finished cigarettes.

[0003] However, the shredded tobacco is curled and easily tangles together, resulting in clumps and agglomerates during transport, which affects the blending accuracy of tobacco and stems. Currently, a loosening machine is placed at the outlet of the tobacco conveyor. Most existing loosening machines drive the loosening rollers through gear transmission, breaking up the clumps and agglomerates. However, as the tobacco falls from the conveyor, it easily gets caught in the gears, causing waste and requiring regular cleaning, increasing the workload for staff.

[0004] Therefore, there is an urgent need for a tobacco loosening device and conveyor to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a tobacco loosening device and conveyor, which can solve the problem that tobacco shreds are easily entangled in the gears of the loosening machine after falling from the conveyor, which not only causes waste of tobacco shreds, but also requires workers to clean the tobacco shreds regularly, resulting in an increased workload for workers.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1 and Figure 2 As shown in the figure, this embodiment provides a tobacco loosening device, which is placed at the outlet of the conveyor that conveys tobacco material. It is used to break up clumps and agglomerates of tobacco, so that the tobacco can be evenly mixed with the stems, thereby ensuring the quality of the finished cigarettes.

[0031] The tobacco loosening device includes a roller motor 1, a loosening roller 2, and two supports 3. The loosening roller 2 includes a connecting sleeve 21 and multiple loosening rods 22. The connecting sleeve 21 is fitted around the outer periphery of the roller motor 1 and is detachably connected to the roller motor 1. The multiple loosening rods 22 are spaced apart around the outer periphery of the connecting sleeve 21. When the roller motor 1 runs, it drives the connecting sleeve 21 to rotate, which in turn causes the multiple loosening rods 22 on the connecting sleeve 21 to rotate. When clumps and agglomerates of tobacco fall from the conveyor, the loosening rods 22 can break up the tobacco, allowing the tobacco to be evenly mixed with the stems, thus ensuring the quality of the finished cigarettes. By using the roller motor 1 to drive the connecting sleeve 21 to rotate, which in turn drives the multiple loosening rods 22 spaced apart around the connecting sleeve 21 to rotate, compared to the existing loosening machine that uses gear transmission to drive the loosening roller 2 to break up the tobacco, the problem of tobacco falling into the gears can be avoided. This not only avoids waste of tobacco but also reduces the workload of the workers. The way the connecting sleeve 21 is detached from the roller motor 1 makes it easy for staff to inspect and maintain the roller motor 1 and the loosening roller 2 at any time, reducing the difficulty of inspection and maintenance of the tobacco loosening device.

[0032] Two supports 3 are connected to both ends of the roller motor 1 along its length. The two supports 3 can support the assembled roller motor 1 and loosening roller 2, facilitating the placement of the tobacco loosening device. Furthermore, the supports 3 can be connected to the support frame of the conveyor, allowing the tobacco loosening device to be directly installed on the conveyor, further simplifying the installation and layout of the tobacco loosening device. The conveyor can be a belt conveyor.

[0033] The tobacco loosening device provided in this embodiment has a connecting sleeve 21 fitted around the outer periphery of the roller motor 1. When the roller motor 1 runs, it drives the loosening roller 2 to rotate, and the loosening rod 22 then breaks up the falling tobacco shreds. By using the roller motor 1 as the power source to drive the loosening roller 2, compared to the existing method of using gear transmission to drive the loosening roller 2, the problem of tobacco shreds falling into the gears can be avoided, thus preventing tobacco waste and reducing the workload of the workers. At the same time, the roller motor 1 directly drives the loosening roller 2 to rotate, making the overall tobacco loosening device smaller and easier to arrange on the conveyor.

[0034] For example, one end of the roller motor 1 along its length is provided with a first threaded area 11, and the connecting sleeve 21 is provided with an internal thread, the internal thread of the connecting sleeve 21 being threaded with the first threaded area 11. Thus, the connecting sleeve 21 can be detached from the roller motor 1 via a threaded connection. After the roller motor 1 is powered off, the operator can quickly detach the loosening roller 2 from the roller motor 1 by rotating it, simplifying the operator's work. Alternatively, a groove with an internal thread can be provided on the outer periphery of the roller motor 1, and a positioning hole can be provided on the outer periphery of the connecting sleeve 21. A bolt is then threaded through the positioning hole and into the internal thread of the groove, enabling the detachable connection of the roller motor 1 and the connecting sleeve 21, thereby allowing the roller motor 1 and the loosening roller 2 to be detached from each other.

[0035] Furthermore, the length of the connecting sleeve 21 is less than the length of the roller motor 1. Thus, after the loosening roller 2 and the roller motor 1 are assembled, a portion of the first threaded area 11 will be exposed on the loosening roller 2. The tobacco loosening device also includes a locking nut 4, which is screwed onto the first threaded area 11 and fits snugly against the connecting sleeve 21. The locking nut 4 improves the tightness of the loosening roller 2 and the roller motor 1, reducing the risk of loosening between the loosening roller 2 and the roller motor 1 after long-term operation, thereby reducing the risk of misalignment of the loosening roller 2 relative to the roller motor 1 and improving the overall quality of the tobacco loosening device.

[0036] In this embodiment, the loosening rod 22 is detachably connected to the connecting sleeve 21. This allows workers to match and install loosening rods 22 of different lengths according to the installation space of the conveyor, enabling the tobacco loosening device to be installed on conveyors of different specifications, thereby improving the versatility of the tobacco loosening device. Furthermore, when storing the tobacco loosening device, multiple loosening rods 22 can be detached from the connecting sleeve 21 and stored separately, making it easier to store the tobacco loosening device.

[0037] For example, the connecting sleeve 21 has multiple mounting slots with internal threads. The end of the loosening rod 22 that connects to the connecting sleeve 21 has a second threaded area, which is screwed into the internal thread of the mounting slot, allowing the loosening rod 22 to be detached from the connecting sleeve 21. By turning the loosening rod 22, the installation and removal of the loosening rod 22 from the connecting sleeve 21 can be completed, reducing the difficulty for workers in installing and removing the loosening rod 22. Alternatively, adhesive bonding can be used to connect the loosening rod 22 to the connecting sleeve 21, and then a desiccant can be used to remove the loosening rod 22, also achieving detachment and connection between the loosening rod 22 and the connecting sleeve 21.

[0038] The loosening rod 22 has an arc-shaped end away from the connecting sleeve 21. When the loosening rod 22 comes into contact with the tobacco, it can break up the clumps and agglomerates of tobacco. The arc-shaped surface of the loosening rod 22 can reduce the damage to the tobacco and further ensure the quality of the finished cigarettes.

[0039] In this embodiment, multiple loosening rods 22 are spaced apart on the outer periphery of the connecting sleeve 21. The multiple loosening rods 22 are evenly distributed on the outer periphery of the connecting sleeve 21, which can further improve the uniformity of the tobacco after dispersing, further improve the blending precision of the tobacco and stems, and improve the quality of the finished cigarette.

[0040] In this embodiment, the tobacco loosening device also includes a frequency converter, which is electrically connected to the roller motor 1. By adjusting the frequency converter, the speed of the roller motor 1 can be adjusted, thereby adjusting the speed of the loosening roller 2. When the conveyor transports the tobacco material, the operator can adjust the speed of the roller motor 1 and the speed of the loosening roller 2 accordingly through the frequency converter based on the conveyor's transport speed, further ensuring the uniformity of the loosened tobacco. The frequency converter is a conventional component in the field of electrical control and is not the focus of this utility model's protection.

[0041] In this embodiment, the roller motor 1 has trunnions 12 at both ends along its length, and the trunnions 12 are nested on the bracket 3. This allows the roller motor 1 to be securely connected to the bracket 3, improving the quality of the tobacco loosening device.

[0042] This embodiment provides a conveyor including the aforementioned tobacco loosening device, wherein the tobacco loosening device is located at the discharge end of the conveyor. Thus, after the tobacco material conveyed by the conveyor falls from the discharge end, the tobacco loosening device can break up clumps and agglomerates of tobacco, allowing the tobacco to mix evenly with the stems, thereby ensuring the quality of the finished cigarettes.

[0043] 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.
