[0025] The utility model provides a technical solution: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, a tobacco logistics belt feeder includes a conveying mechanism 1, and a dust-proof mechanism 2 arranged at one end of the conveying mechanism 1 for assisting material dumping. The dust-proof mechanism 2 includes an upper box 3 and a lower box 4, and the lower box 4 is located below the upper box 3. An exhaust mechanism 5 is arranged on the lower box 4 to absorb ash and slag raised during the fall. A collecting mechanism 6 is arranged inside the exhaust mechanism 5 to filter and collect the ash and slag. A limiting mechanism 7 is used to achieve a connection between the upper box 3 and the lower box 4. By providing the dust-proof mechanism 2 As the materials fall in the upper and lower boxes 3 and 4 in turn, the exhaust mechanism 5 can intercept larger lumps of ash, allowing fine dust to enter the long tube 10. The collecting mechanism 6 can filter and collect the ash again for the convenience of subsequent cleaning. During this period, the limiting mechanism 7 and the shell 8 are used in coordination, so that the lower box 4 can be located outside the upper box 3 for up and down adjustment, thereby adapting to the different heights of the workstations below for flexible use. The device can effectively intercept and collect tobacco stem fragments and dust in a sealed manner.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the air extraction mechanism 5 includes a long tube 10, which is fixedly arranged in the lower box 4, and the outer side of the long tube 10 is fixedly connected with an external tube 11, and the other end of the external tube 11 is connected to the external pump body, and the outer side of the external tube 11 is fixedly connected with a bellows 12, and the outer side of the long tube 10 is provided with an air inlet 13, and a filter plate 14 is fixedly arranged in the air inlet 13. By setting the air extraction mechanism 5, as the material is in the upper box 3 and the lower box 4 As the ash falls inside, the pump body generates suction into the external pipe 11, so that the ash can enter the long tube 10 through the air inlet hole 13. During this period, the filter plate 14 can intercept larger ash blocks, so that fine dust can enter the long tube 10. The air inlet holes 13 are evenly distributed on the outside of the long tube 10. The long tube 10 is provided with two groups, and the two groups of long tubes 10 are symmetrically distributed on the bottom 4 of the box body, which can further improve the absorption of the raised ash.

[0027] like Figure 1 , Figure 2 and Figure 3As shown, the collecting mechanism 6 includes a filter cartridge 15, a cover plate 16 is fixedly installed on the bottom end of the filter cartridge 15, and the cover plate 16 is connected to the long tube 10 by threaded engagement. A handle 17 is fixedly installed on the bottom end of the cover plate 16. By providing the collecting mechanism 6, as fine ash enters the long tube 10, the ash can be collected in the interior of the filter cartridge 15, and the filter cartridge 15 can perform secondary filtering on the ash again. Subsequently, the filter cartridge 15 can be taken out of the long tube 10 by threaded separation between the cover plate 16 and the long tube 10, so as to facilitate the cleaning of the ash.

[0028] like Figure 1 and Figure 4 As shown, the limiting mechanism 7 includes a T-slot 18, and the T-slot 18 is opened on the outer side of the upper box body 3. A T-block 19 is inserted inside the T-slot 18, and the T-block 19 is fixedly installed on the inner wall of the lower box body 4. The outer side of the T-block 19 abuts against the inner wall of the T-slot 18. Two groups of T-blocks 19 are provided, and the two groups of T-blocks 19 are equidistantly arranged on the inner wall of the lower box body 4. By providing the limiting mechanism 7, the upper box body 3 and the lower box body 4 can be slidably connected up and down. As the lower box body 4 moves outside the upper box body 3, the T-block 19 can slide inside the T-slot 18, which effectively improves the stable connection between the upper box body 3 and the lower box body 4.

[0029] like Figure 1 and Figure 4 As shown, the transmission mechanism 9 includes a rack 20, and the rack 20 is fixedly arranged on the outer side of the lower box 4. The outer side of the rack 20 is connected to a gear 21 through tooth meshing. A rotating shaft 22 is fixedly installed in the gear 21. The rotating shaft 22 is rotatably connected to the inner wall of the outer shell 8. A servo motor 23 is fixedly installed on the outer side of the outer shell 8. The end of the rotating shaft of the servo motor 23 is fixedly connected to the rotating shaft 22. By providing the transmission mechanism 9, as the servo motor 23 drives the rotating shaft 22 to rotate, that is, the gear 21 can drive the rack 20 to move in position, so that the lower box 4 can be located on the outer side of the upper box 3 to adjust its position.

[0030] like Figure 2 and Figure 4As shown, a cylinder 24 is fixedly installed on the top of the box body 3, and a long plate 25 is fixedly connected to the telescopic end of the cylinder 24, and the long plate 25 is in contact with the inner wall of the feed port on the box body 3. Plastic sheets 26 are equidistantly arranged at the bottom of the long plate 25, and a surrounding plate 27 is arranged on one side of the long plate 25. The surrounding plate 27 is fixedly arranged on the outer side of the box body 3. As the material enters the interior of the box body 3 from the conveying mechanism 1, the ash raised when the material just falls will be in the interior of the box body 3. The plastic sheet 26 can prevent the ash from flowing from the feed port on the box body 3 to the outside to a certain extent, and the cylinder 24 can adjust the height of the long plate 25 to prevent the material from being conveyed too fast, causing a large amount of ash to be generated and flow out, so that the plastic sheet 26 can move downward to block it.

[0031] The utility model provides a tobacco logistics belt feeder, and the specific working principle is as follows:

[0032] When the device is in use, the conveying mechanism 1 can convey the materials one by one to the interior of the upper box 3 and the lower box 4, and drop them downward. As the pump body generates suction in the external pipe 11, the ash can enter the interior of the long tube 10 through the air inlet 13. During this period, the filter plate 14 can intercept larger block ash, so that fine dust can enter the long tube 10. As the fine ash enters the long tube 10, the ash can be collected in the interior of the filter cartridge 15, and the filter cartridge 15 can perform secondary filtering on the ash again. Subsequently, the filter cartridge 15 can be taken out of the long tube 10 by threaded separation between the cover plate 16 and the long tube 10, so as to facilitate the cleaning of the ash. As the servo motor 23 drives the rotating shaft 22 to rotate, that is, the gear 21 can drive the rack 20 to move in position, so that the lower box body 4 can be located outside the upper box body 3 for position adjustment, during which the T-block 19 can slide inside the T-slot 18, effectively improving the stable connection between the upper box body 3 and the lower box body 4. This structure can effectively intercept and collect tobacco stem fragments and dust in a sealed manner. The ash raised when the material just falls will be inside the upper box body 3. The plastic sheet 26 can prevent the ash from flowing to the outside from the feed port on the upper box body 3 to a certain extent, and the cylinder 24 can adjust the height of the long plate 25 to prevent the material from being transported too fast, causing a large amount of ash to flow out, so that the plastic sheet 26 can move downward to block it.
