[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.
[0026] The fluidized bed of a cigarette making machine is used to form loose cut tobacco into a cut tobacco bundle, including a conveying part for conveying cut tobacco and a converging part for converging cut tobacco into a cut tobacco bundle. The conveying part conveys cut tobacco through positive - pressure airflow, and the cut tobacco moves along the positive - pressure airflow direction 3 into the converging part. However, the traditional fluidized bed of a cigarette making machine has no requirement for cut tobacco sorting and cannot meet the strict requirements of the production process of heat - not - burn cigarettes for the highly ordered arrangement of cut tobacco bundles.
[0027] To solve the above problems, the present utility model provides a flow guiding device for a fluidized bed of a cigarette making machine, and the specific structure is as follows:
[0028] As shown in Figure 1 and Figure 2 The flow guiding device for the fluidized bed of the cigarette making machine includes a flow guiding part 1 arranged between a conveying part and a converging part. The flow guiding part 1 includes a plurality of flow guiding blocks 2 for guiding the direction of the positive pressure air flow. During use, the flow guiding blocks 2 can guide the direction of the positive pressure air flow, promote the formation of a more orderly arrangement structure of the cut tobacco when it enters the converging part, so as to obtain a cut tobacco bundle with a high degree of arrangement order, and meet the requirements for the high-precision arrangement of the cut tobacco bundle in heat-not-burn cigarettes.
[0029] In some embodiments, to make the guiding of the air flow by the flow guiding blocks 2 smoother, the flow guiding blocks 2 are in a semi-circular shape or an airfoil shape. Among them, the airfoil-shaped flow guiding block 2 is as shown in Figure 1 One end is a tip, the other end is an arc, and the side surface is a streamline profile. The semi-circular or airfoil shape is designed to optimize the streamline when the air flow passes through, reduce resistance, and at the same time use its unique shape to guide the cut tobacco to move along a specific path. As a further improvement of the above embodiment, the tip of the semi-circular or airfoil-shaped flow guiding block 2 faces the axial arrangement direction 4 of the cut tobacco bundle in the converging part, promoting the cut tobacco to be arranged along the axial arrangement direction 4 of the cut tobacco bundle when it enters the converging part.
[0030] In some embodiments, the flow guiding part 1 includes a flow guiding plate 5, and a plurality of flow guiding blocks 2 are evenly spaced along the length direction of the flow guiding plate 5, further enhancing the uniformity of the cut tobacco arrangement. As a further improvement of this embodiment, the flow guiding plate 5 is provided with an inclined surface that is inclined with respect to the movement direction of the cut tobacco, and the flow guiding blocks 2 are evenly spaced on the inclined surface. The inclined surface can provide a smooth transition air flow channel, reduce the generation of air flow resistance and eddy currents, and ensure the smooth movement of the cut tobacco.
[0031] In some embodiments, the flow guiding blocks 2 and the flow guiding plate 5 are detachably connected, and the detachable connection can be a bolt connection, which is convenient for the maintenance and replacement of the flow guiding blocks 2.
[0032] In some embodiments, the flow guiding part 1 further includes a mounting plate 6. The mounting plate 6 is connected to the conveying part and is detachably connected to the flow guiding plate 5, and can replace a suitable flow guiding plate 5 according to the length of different cut tobacco sheets, improving the adaptability of the equipment. As a further improvement of this embodiment, as shown in Figure 2 The mounting plate 6 is provided with an L-shaped mounting part 7, and the flow guiding plate 5 is provided with an L-shaped fitting part 8. The L-shaped mounting part 7 abuts against the L-shaped fitting part 8. Specifically, the long side of the L-shaped mounting part 7 abuts against the short side of the L-shaped fitting part 8, and the short side of the L-shaped mounting part 7 abuts against the long side of the L-shaped fitting part 8, and the two are connected by bolts. This L-shaped surface fitting design helps to save space and can quickly locate the relative positions of the mounting plate 6 and the flow guiding plate 5 during installation.
[0033] In some embodiments, the deflector 5 abuts against the converging portion. Since the mounting plate 6 is connected to the conveying portion, at this time, the conveying portion, the deflector portion 1 and the converging portion can form a complete sealing structure to ensure that neither the air flow nor the cut tobacco leaks out.
[0034] In some embodiments, the deflector 5 is provided with a smooth layer for reducing turbulence. The smooth treatment is beneficial to reducing the frictional resistance when the air flow passes through the surface of the deflector 5 and reducing turbulence.
[0035] The present utility model also provides a fluidized bed for a cigarette making machine, including the deflector device for the fluidized bed of the cigarette making machine as described above.
