[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0029] like Figures 1 to 3As shown, this embodiment provides a secondary sorting device for tobacco stems, which includes a frame 1, a separation mechanism 2, and a negative pressure generator. The frame 1 has a feed inlet 11, a separation channel 12, and a discharge outlet 13 connected in sequence. The separation mechanism 2 includes a drive assembly 21 and at least one set of separation components 22. The drive assembly 21 is mounted on the frame 1, and the drive assembly 21 and the separation components 22 are driven together to drive the separation components 22 to rotate. The separation components 22 are located at the feed inlet 11 and are used to break up clumps of stems entering from the feed inlet 11. The separation channel 12 is used to separate the clumps of stems broken up by the separation components 22. The negative pressure generator is located at the discharge outlet 13 and can generate suction to draw out the tobacco shreds in the separation channel 12.

[0030] The tobacco stem secondary sorting device of this invention, after the stem mixture from the first stem removal falls from the feed inlet 11, it enters the separation component 22. The drive component 21 rotates the separation component 22, thoroughly breaking up the clumps of stems. The broken-up clumps then fall into the separation channel 12, where they are fully dispersed and layered. Finally, under the action of the negative pressure generator, the lighter tobacco shreds are sucked away and collected, while the heavier stems fall into the collection bin, thus achieving complete separation of tobacco shreds and stems. With this design, this invention effectively breaks up clumps of stems through the separation mechanism 2, creating favorable conditions for subsequent sorting and effectively solving the problem of tobacco waste caused by the ineffective separation of tobacco shreds and stems in existing secondary sorting and dispersion devices.

[0031] In some embodiments, the separation component 22 includes a rotating shaft 221 and multiple sets of separation blades 222. The drive component 21 and the rotating shaft 221 are connected by a drive, and the multiple sets of separation blades 222 are axially spaced on the rotating shaft 221. This increases the separation area of ​​the separation component 22, and the separation blades 222 can break up the clumps of filaments entering from the feed inlet 11.

[0032] In this embodiment, a set of separating blades 222 includes four blade bodies 2221. The four blade bodies 2221 are arranged circumferentially at intervals on the rotating shaft 221, with an included angle of 90° between two adjacent blade bodies 2221. This arrangement can further ensure the separation effect of the separating assembly 22.

[0033] Furthermore, the shape of the blade body 2221 includes, but is not limited to, a triangle. Setting the shape of the blade body 2221 to a triangle can effectively prevent wire blockage.

[0034] In some embodiments, the drive assembly 21 includes a drive motor 211 and a speed regulator. The drive motor 211 is mounted on the frame 1, and its output shaft is connected to the separation assembly 22 to drive the separation assembly 22 to rotate. The speed regulator is electrically connected to the drive motor 211, and the speed regulator can be used to adjust the rotational speed of the separation assembly 22. This allows the speed of the separation assembly 22 to be adjusted according to the actual situation of the mixture of stems and shreds falling from the feed inlet 11 after the first removal of stems, thereby ensuring the separation effect.

[0035] In this embodiment, the drive motor 211 includes, but is not limited to, a servo motor or a variable frequency motor. Servo motors offer advantages such as high-precision control, rapid response, stable and efficient operation, energy saving, and easy maintenance; variable frequency motors offer advantages such as significant energy saving, a wide speed range, smooth start-up and operation, and high control precision.

[0036] In some embodiments, the inner wall of the separation channel 12 is Z-shaped. This configuration can further improve the layering and dispersion of the broken-up clumps of stems.

[0037] In this embodiment, the secondary sorting device for tobacco stems includes a first separation structure 3 and a second separation structure 4. The first separation structure 3 and the second separation structure 4 are respectively disposed on two opposite side walls within the cavity of the frame 1. The first separation structure 3 has a plurality of first separation protrusions 31 connected in sequence, and the second separation structure 4 has a plurality of second separation protrusions 41 connected in sequence. One second separation protrusion 41 corresponds to two adjacent first separation protrusions 31. In this arrangement, a separation channel 12 is formed between the plurality of first separation protrusions 31 and the plurality of second separation protrusions 41.

[0038] Optionally, the channel wall of the separation channel 12 is a front-to-back swing structure. The channel wall of the separation channel 12 is inclined at an angle relative to the horizontal plane, and its swing direction is the front-to-back direction. This allows the strands to better adhere to the channel wall, resulting in a more obvious separation effect.

[0039] In this embodiment, the secondary sorting device for tobacco stems also includes a baffle structure 5. The baffle structure 5 is disposed in the cavity of the frame 1 and located on the side of the feed inlet 11 away from the separation component 22. The baffle structure 5 can prevent the clumps of stems in the feed inlet 11 from being sucked away.

[0040] Specifically, the baffle structure 5 includes, but is limited to, a baffle plate, wherein the tilt angle of the baffle plate is adjustable, so that the position of the baffle plate can be adjusted at any time according to the actual situation, thereby achieving the purpose of preventing the clumps of filaments from being sucked away from the feed inlet 11.

[0041] Optionally, the tilt angle of the baffle can be adjusted by rotating the motor and the baffle transmission connection, or the tilt angle of the baffle can be adjusted by manual rotation.

[0042] The advantages of this utility model are as follows:

[0043] 1. The separation mechanism effectively breaks up the clumps of stems, creating favorable conditions for subsequent sorting.

[0044] 2. The baffle structure prevents the tobacco from being sucked away prematurely, ensuring that all materials are fully dispersed.

[0045] 3. The inner wall of the separation channel 12 is Z-shaped, which enhances the separation effect and improves the sorting accuracy.

[0046] 4. The overall structure is simple, and the operation and maintenance are convenient. It can effectively reduce tobacco waste and improve economic efficiency.

[0047] 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 other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations 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.
