[0001] The utility model relates to the technical field of tobacco production, in particular to a foreign matter removal device for tobacco wire making. Background Technique

[0002] Tobacco is an important cash crop, mainly used for making cigarettes, cigars and other items. During the production process of tobacco, the tobacco leaves are rolled up and then cut into shreds by a cutting tool. If dust prevention is not paid attention to during the production process of tobacco shreds, there will be dust foreign matters inside the tobacco shreds after they are cut. For these foreign matters, an air sieve is used to remove them.

A second bevel gear 12 is meshed at the top end of the third bevel gear 13. A rotating shaft 16 is installed inside the second bevel gear 12, and the left side of the rotating shaft 16 extends into the feed hopper 14 and is movably connected to the feed hopper 14. A blanking plate 15 is installed on the outer side wall of the rotating shaft 16. The second bevel gear 12 is meshed with the third bevel gear 13 at the top end of the rotating rod 11, and the first bevel gear 10 is meshed with the third bevel gear 13 at the bottom end of the rotating rod 11. A plurality of blanking plates 15 are provided, and the plurality of blanking plates 15 are evenly distributed on the outer side wall of the rotating shaft 16 to uniformly turn the cut tobacco to make it uniformly blank.

[0024] Specifically, as Figure 1 and Figure 2 shown, when in use, when the belt wheel mechanism 8 is started, the belt wheel above the inside of the belt wheel mechanism 8 rotates and drives the first bevel gear 10 to rotate through the connecting shaft 9. When the first bevel gear 10 rotates, it drives the third bevel gear 13 to rotate through the rotating rod 11, so that the second bevel gear 12 above the rotating rod 11 rotates. When the second bevel gear 12 rotates, the rotating shaft 16 installed inside it will rotate inside the feed hopper 14, so that the blanking plate 15 on the outer side wall of the rotating shaft 16 rotates to stir the cut tobacco material introduced into the material conveying cylinder 17 through the feed hopper 14, so that the cut tobacco material uniformly enters the material conveying cylinder 17.

[0025] Embodiment 2: Protective mesh covers 4 are fixed at the bottom ends of both the first outlet 3 and the second outlet 6, and metal wires 5 are movably installed at the bottom ends inside the protective mesh covers 4;

[0026] Specifically, as Figure 1 and Figure 4As shown, when the material buckets are placed below the first outlet 3 and the second outlet 6, and the material discharged from the first outlet 3 and the second outlet 6 is to be discharged, the protective net cover 4 can be sleeved on the outer side walls of the first outlet 3 and the second outlet 6, and then the wire 5 is tightened to fix the protective net cover 4 on the outer side wall of the material bucket for receiving the material, so that the material discharged from the first outlet 3 and the second outlet 6 is not easily splashed outwards.

[0027] Embodiment 3: A mounting seat 20 is installed at the top end inside the sieve drum 1. A threaded rod 21 is movably installed inside the mounting seat 20, and a servo motor 19 is installed on the right side of the threaded rod 21. A moving rod 22 is movably arranged on the outer side wall of the threaded rod 21, and a brush 24 is fixed at the bottom end of the moving rod 22. Sliding blocks 25 are fixed at the front and rear ends of the moving rod 22. Sliding grooves 23 are arranged at both ends of the sliding block 25, and the sliding grooves 23 are arranged at the top end inside the sieve drum 1. The cross-section of the sliding groove 23 is larger than the cross-section of the sliding block 25. A sliding structure is formed between the sliding groove 23 and the sliding block 25 to guide the movement of the brush 24, so that the brush 24 moves stably. Internal threads are uniformly arranged at the top end inside the moving rod 22. A threaded connection is formed between the moving rod 22 and the threaded rod 21, so that the brush 24 moves uniformly left and right;

[0028] Specifically, as Figure 1 and Figure 2 shown, start the servo motor 19 to drive the threaded rod 21 to rotate. The rotation of the threaded rod 21 guides the moving rod 22 through the sliding of the sliding block 25 inside the sliding groove 23, so that the moving rod 22 drives the brush 24 to move left and right on the outer side wall of the rotating mesh cylinder 7 to clean the outer side wall of the mesh cylinder 7.

[0029] Working principle: When the utility model is in use, the material buckets for receiving materials are respectively placed below the first outlet 3 and the second outlet 6. After being placed below the first outlet 3 and the second outlet 6, the protective net cover 4 is sleeved on the outer side walls of the first outlet 3 and the second outlet 6, and then the wire 5 is tightened to fix the protective net cover 4 on the outer side wall of the material bucket for receiving materials. Then, the cut tobacco is put into the inside of the feed hopper 14. At the same time, the pulley mechanism 8 is started. The pulley mechanism 8 drives the auger 18 to rotate to uniformly convey the tobacco shreds. At the same time, when the pulley mechanism 8 rotates, the pulley above the pulley mechanism 8 inside rotates and drives the first bevel gear 10 to rotate through the connecting shaft 9. The first bevel gear 10 rotates to drive the third bevel gear 13 to rotate, and the third bevel gear 13 rotates to drive the second bevel gear 12 to rotate, so that the rotating shaft 16 installed inside drives the blanking plate 15 to rotate to stir the cut tobacco material introduced into the inside of the material conveying cylinder 17 through the feed hopper 14, so that the cut tobacco material uniformly enters the inside of the material conveying cylinder 17. Then, under the uniform conveying of the auger 18, it enters the inside of the mesh cylinder 7. The mesh cylinder 7 rotates under the action of the wind wheel 2 to perform rotational screening on the material, so that the small particle dust in the tobacco shreds passes through the mesh cylinder 7 and is discharged and led out through the second outlet 6, while the large cut tobacco is discharged through the first outlet 3, thus completing the removal of dust and foreign matters inside the cut tobacco.
