[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-6 As shown, this utility model provides a technical solution: a device for controlling the centering of the flavoring thread in a filter rod, comprising a tobacco tongue 1, a flavoring thread guide tube 2, a connecting plate 3, and an adjusting assembly. The top of the tobacco tongue 1 is provided with a fixing plate 11 for connecting the tobacco tongue 1 to a filter rod production equipment. The flavoring thread guide tube 2 includes a vertical part 21 and a horizontal part 22. The lower end of the vertical part 21 is placed inside the tobacco tongue 1, and the upper end extends vertically upward through the top of the tobacco tongue 1. One end of the horizontal part 22 is connected to the lower end of the vertical part 21, and the other end extends vertically upward through the top of the tobacco tongue 1. The adjusting assembly extends horizontally at one end and includes a hollow sleeve 4 and a first screw 5. The hollow sleeve 4 is positioned above the tongue 1, and the vertical part 21 is movably inserted into the hollow sleeve 4. The first screw 5 penetrates vertically through the side wall of the hollow sleeve 4 and is threaded onto the side wall of the hollow sleeve 4. When the first screw 5 is tightened, its end presses against the vertical part 21. One end of the connecting plate 3 is connected to the fixing plate 11, and the other end is connected to the hollow sleeve 4 to support and fix the hollow sleeve 4.

[0023] This invention uses a connecting plate 3 to support and fix the hollow sleeve 4 above the tobacco tongue 1, allowing the vertical part 21 of the flavoring thread guide tube 2 to be movably inserted into the hollow sleeve 4. The flavoring thread guide tube 2 is clamped and fixed by the hollow sleeve 4 and the first screw 5. In use, the first screw 5 is loosened, the flavoring thread guide tube 2 is rotated and its height is adjusted so that the center of the horizontal part 22 of the flavoring thread guide tube 2 is coaxial with the center of the tobacco tongue 1. Then, the first screw 5 is tightened to clamp the vertical part 21 of the flavoring thread guide tube 2 into the hollow sleeve 4, thereby fixing the flavoring thread guide tube 2. This ensures that the flavoring thread inside the flavoring thread guide tube 2 is located at the center of the cellulose acetate bundle inside the tobacco tongue 1, solving the problem of difficulty in centering the flavoring thread in the filter rod.

[0024] Furthermore, the hollow sleeve 4 includes a coarse adjustment sleeve 41, a fine adjustment sleeve 42, and a second screw 43. The coarse adjustment sleeve 41 is a cylindrical hollow tube. The vertical part 21 is movably inserted into the coarse adjustment sleeve 41. The first screw 5 vertically penetrates the side wall of the coarse adjustment sleeve 41 and is threaded onto the side wall of the coarse adjustment sleeve 41. The outer wall of the coarse adjustment sleeve 41 is provided with an external thread 411. The outer wall of the coarse adjustment sleeve 41 is provided with a keyway 412 extending vertically. The fine adjustment sleeve 42 is provided with a through hole extending vertically. The coarse adjustment sleeve 41 is movably connected into the fine adjustment sleeve 42. The fine adjustment sleeve 42 is divided into three parts from bottom to top and respectively... The structure consists of a lower support 421, a fine-tuning nut 422, and an upper support 423. The lower support 421 is connected to the connecting plate 3. The upper support 423 is fixedly connected to the lower support 421. The fine-tuning nut 422 is rotatably connected between the lower support 421 and the upper support 423. The fine-tuning nut 422 is threaded onto the external thread 411 on the outside of the coarse-tuning sleeve 41. The second screw 43 penetrates vertically through the side wall of the upper support 423 and is threaded onto the side wall of the upper support 423. When the second screw 43 is tightened, its end presses against the bottom of the keyway 412 on the outer wall of the coarse-tuning sleeve 41. The diameter of the second screw 43 is equal to the width of the keyway 412.

[0025] In use, loosen the second screw 43. Since the coarse adjustment sleeve 41 is threaded into the fine adjustment nut 422, and the second screw 43 is inserted into the keyway 412 on the outer wall of the coarse adjustment sleeve 41, and the diameter of the second screw 43 is equal to the width of the keyway 412, the rotation of the coarse adjustment sleeve 41 is restricted. Rotate the fine adjustment nut 422, and the coarse adjustment sleeve 41 drives the fragrance line guide tube 2 to slide up and down in the fine adjustment sleeve 42, so that the height of the fragrance line guide tube 2 can be finely adjusted, making the centering of the fragrance line in the filter rod more accurate.

[0026] Furthermore, the spice thread guide tube 2 is an L-shaped hollow tube formed by the arc transition connection of the vertical part 21 and the horizontal part 22. The arc transition design can prevent the spice thread from rubbing and breaking at the corner where the vertical part 21 and the horizontal part 22 are connected.

[0027] Furthermore, the tongue 1 is a trumpet-shaped hollow tube, which facilitates the insertion of cellulose acetate bundles from the larger diameter end of the tongue 1.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
