When the tobacco stems move to the bottom of the first wiping component 4, the electrostatic belt 44 is driven to rotate by the transmission wheel 45, and the electrostatic belt 44 is rubbed by the wiping wheel 43 at the same time, so that the electrostatic belt 44 generates static electricity, so that the electrostatic belt 44 has an adsorption force on the hemp fibers, thereby achieving the function of removing the hemp fibers from the tobacco stems. The hemp fibers on the tobacco stems can be electrostatically absorbed by the first wiping component 4, and the hemp fibers and other debris can be collected by the first collecting box 5, so as to facilitate the recycling of the hemp fibers.

[0044] Example 3

[0045] See also Figures 5 to 7 The difference between this embodiment and embodiment 2 is that it also includes a feeding device, which includes a conveying pipe 13, a rotating shaft 14 and a spiral piece 15. The upper part of the conveying pipe 13 is cylindrical, and the lower part is an inverted cone. The conveying pipe 13 is provided with the rotating shaft 14 and the spiral piece 15, and the spiral piece 15 matches the inner cavity of the conveying pipe 13. The spiral piece 15 is installed on the rotating shaft 14, and the rotating shaft 14 is connected to the first motor 16. The lower side of the conveying pipe 13 is provided with a feeding port 17, and the lower end of the conveying pipe 13 is arranged in a storage box 18. The upper end of the conveying pipe 18 is provided with a material guide plate 19, and the material guide plate 19 is located above the thinning component 2.

[0046] When the present invention is used, tobacco stems are placed in a storage box 18, and the storage box 18 is located at a low position, which is convenient for placing tobacco stems. A conveying pipe 13 is provided in the storage box 18, and a feed port 17 is provided on the lower side of the conveying pipe 13. The tobacco stems enter the conveying pipe 13 from the feed port 17. A rotating shaft 14 and a spiral blade 15 are provided in the conveying pipe 13. The first motor 16 drives the rotating shaft 14 and the spiral blade 15 to rotate. When the spiral blade 15 rotates, it drives the tobacco stems to move upward, thereby transporting the tobacco stems from a low position to a high position, and finally the tobacco stems are discharged from the upper end of the conveying pipe. A guide plate 19 is provided at the upper end of the conveying pipe 13, and the guide plate 19 is located above the thinning component 2. The tobacco stems fall into the thinning component 2 along the guide plate 19. The upper part of the delivery tube 13 is cylindrical, and the lower part is inverted cone. The inner diameter of the lower end of the inverted cone is larger than the inner diameter of the upper end. The inner diameter of the delivery tube gradually increases during the upward movement of the tobacco stems, thereby reducing the risk of the tobacco stems being clamped and maintaining the integrity of the tobacco stems as much as possible during the process of the tobacco stems being transported from the lower end to the upper end of the delivery tube 13. Optionally, the angle between the generatrix of the inverted cone portion of the delivery tube 13 and the axis is 3 to 10 degrees.

[0047] Specifically, the spiral piece 15 at the feed port 17 is provided with a movable tooth block 20, the movable tooth block 20 is magnetic, the movable tooth block 20 is slidably connected with the spiral piece 15, the spiral piece 15 is provided with a spring 21 for pushing the movable tooth block 15 to move away from the rotating shaft 14, and the upper part of the feed port 17 is provided with a baffle 22, the baffle 22 and the spiral piece 15 leave a gap of 1 to 2 mm, and the baffle 22 is provided with a magnet that repel the movable tooth block 20. The baffle 22 and the movable tooth block 20 are made of strong magnetic materials. When the movable tooth block 20 rotates to a position close to the baffle 22 as the spiral piece 15 rotates, the baffle 22 and the movable tooth block 20 repel each other, thereby pushing the movable tooth block 20 to overcome the spring force and move toward the center of the spiral piece 15, and the movable tooth block 20 brings the tobacco stems in the conveying pipe 13 to the center, thereby preventing the tobacco stems from being clamped by the spiral piece 15 and the conveying pipe 13 when moving upward, thereby improving the integrity of the tobacco stems during the conveying process. The spring 21 in a natural state just pushes the end of the movable tooth block 20 to be flush with the end of the spiral piece 15 .

[0048] Example 4

[0049] See also Figure 8The difference between this embodiment and the embodiment 3 is that a conveyor belt 13 is provided on the side of the baffle 22 facing the spiral sheet 15, and the conveyor belt 13 is wound around a roller 23, and the roller 23 is connected to a second motor (not shown), and the roller 23 drives the conveyor belt 13 to rotate downward. When the second motor rotates, it drives the roller 23 to rotate, thereby driving the conveyor belt 24 to rotate, and the conveyor belt 24 moves the tobacco stems in contact with the baffle 22 downward to prevent the tobacco stems at this position from being clamped in the gap of the conveying pipe 13 by the spiral sheet 15 when moving upward, thereby preventing the tobacco stems from being crushed and improving the integrity of the tobacco stems.
