[0031] The specific arrangement and function of the screening structure 6 and the limiting structure 7 will be described in detail below.

[0032] Reference Figure 2 and Figure 3As shown, in this embodiment: the screening structure 6 includes a rectangular tube 601, the rectangular tube 601 is connected to the feed hopper 3, both sides of the rectangular tube 601 are fixedly connected with servo motors 602, the output ends of the two servo motors 602 both pass through the rectangular tube 601, the output ends of the servo motors 602 are fixedly connected with convex plates 605, the inner wall of the rectangular tube 601 is fixedly connected with a frame 603, the surface of the frame 603 is slidably penetrated with two round rods 606, the end of the round rod 606 away from the convex plate 605 is fixedly connected with a driving plate 608, the arc surface of the round rod 606 is sleeved with a spring 607, the two ends of the spring 607 are respectively fixedly connected to the rectangular plate and the frame 603, and the inner wall of the rectangular tube 601 is slidably connected with a filter screen 604. Grooves 609 are provided on both sides of the filter 604. The inner wall of the groove 609 is rotatably connected with a rotating shaft 610. The movement of the filter 604 drives the rotating shaft 610 to slide along the inner wall of the rectangular tube 601. The rotating shaft 610 rotates in the groove 609 when moving. The rotating shaft 610 reduces the friction force of the filter 604 when moving in the rectangular tube 601, thereby reducing the energy loss of the servo motor 602. Two protective pads 611 are fixedly connected to one side of the frame 603 close to the filter 604. Both protective pads 611 are made of rubber. The filter 604 is attached to the surface of the protective pad 611. The protective pad 611 prevents the filter 604 from hitting the surface of the frame 603, causing damage to the frame 603 and the filter 604. The surface of the filter 604 is slidably penetrated by a plurality of limit rods 612, which are all fixedly connected to the surface of the frame 603. The filter 604 slides along the surface of the limit rods 612 when moving. The limit rods 612 limit the moving path of the filter 604, thereby preventing the filter 604 from escaping from the rectangular tube 601.

[0033] Reference Figure 4 and Figure 5As shown, specifically, the limiting structure 7 includes a bracket 71, the bracket 71 is fixedly connected to the discharge pipe 5, the surface of the bracket 71 is rotatably connected with a bidirectional screw 72, the surface of the bidirectional screw 72 is threadedly connected with two driving arms 73, the sides of the two driving arms 73 close to each other are fixedly connected with a U-shaped plate 74, and the surface of the discharge pipe 5 is covered with a collecting bag 75. Both sides of the discharge pipe 5 are fixedly connected with a plurality of hooks 76, the inner wall of the U-shaped plate 74 is fixedly connected with two anti-slip strips 78, the edge of the collecting bag 75 is hung on the surface of the hook 76, so that the spike end of the hook 76 pierces the collecting bag 75, the hook 76 is convenient for temporarily limiting the collecting bag 75, the collecting bag 75 is tightly attached to the surface of the discharge pipe 5 by the extrusion of the anti-slip strip 78, and the anti-slip strip 78 further improves the effect of the U-shaped plate 74 limiting the collecting bag 75. A turntable 77 is fixedly connected to the surface of the bidirectional screw 72 . The vertical section of the turntable 77 is in a cross shape. The rotation of the turntable 77 drives the bidirectional screw 72 to rotate in the bracket 71 . The turntable 77 facilitates the rotation of the bidirectional screw 72 .

[0034] Working principle: when nicotine needs to be added into the graded feeder, first drive the two servo motors 602, then pour the nicotine raw material into the rectangular tube 601, the nicotine raw material will fall onto the surface of the filter 604, the rotation of the servo motor 602 will drive the convex plate 605 to rotate, and the convex plate 605 will squeeze the round rod 606 after rotating to a suitable angle, and the round rod 606 will slide in the frame 603 when squeezed, and the round rod 606 will drive the rectangular plate to move towards the filter 604 when moving, and the rectangular plate will stretch the spring 607 when moving, and at this time the spring 607 will be stretched. 07 is in a stretched state. When the rectangular plate moves to a suitable position, it squeezes the filter screen 604. The filter screen 604 slides along the inner wall of the rectangular tube 601 with the help of the squeezing force of the rectangular plate. The movement of the filter screen 604 drives the shaft 610 to slide along the inner wall of the rectangular tube 601. The shaft 610 rotates in the groove 609 when moving. The shaft 610 reduces the friction of the filter screen 604 when moving in the rectangular tube 601, thereby reducing the energy loss of the servo motor 602. The filter screen 604 slides along the surface of the limit rod 612 when moving. The limit rod 612 reaches The filter 604 is limited in its movement path, thereby preventing the filter 604 from falling out of the rectangular tube 601. When the convex plate 605 is rotated to a suitable angle, the convex plate 605 will be free from the squeeze on the round rod 606, and the rectangular plate will be reset with the help of the contraction force of the spring 607. The filter 604 will move toward the direction close to the frame 603 with the help of its own gravity until the filter 604 fits on the surface of the protective pad 611. The protective pad 611 can prevent the filter 604 from hitting the surface of the frame 603, causing damage to the frame 603 and the filter 604. The servo motor 602 is driven to rotate, thereby driving the filter 604 to move up and down in the rectangular tube 601. At this time, the nicotine raw materials on the surface of the filter 604 are driven by the vibration of the filter 604. The nicotine raw materials that meet the requirements will fall from the holes on the surface of the filter 604 into the feed hopper 3. The nicotine raw materials in the feed hopper 3 will fall into the first shell 1. The spiral driving rod in the first shell 1 will drive the nicotine raw materials into the second shell 2. The conveyor belt in the second shell 2 will transfer the nicotine raw materials to the discharge pipe 5, so that the nicotine raw materials are discharged from the discharge pipe 5.

[0035] When it is necessary to collect the nicotine raw materials discharged from the discharge pipe 5, first rotate the turntable 77. The rotation of the turntable 77 will drive the bidirectional screw 72 to rotate in the bracket 71. The rotation of the bidirectional screw 72 will drive the two driving arms 73 to move away from each other by means of the thread. The movement of the two driving arms 73 will drive the two U-shaped plates 74 to move away from each other. When the U-shaped plates 74 move to a suitable position, the collecting bag 75 is sleeved on the outer surface of the discharge pipe 5, and then the edge of the collecting bag 75 is hung on the surface of the hook 76, so that the spike end of the hook 76 pierces the collecting bag 75. The hook 76 is convenient for temporarily limiting the collecting bag 75. When the collecting bag 75 is hung on the hook 76, it moves in the opposite direction. The turntable 77 is rotated in the direction of rotation. The rotation of the turntable 77 will drive the bidirectional screw 72 to rotate. The bidirectional screw 72 will drive the two driving arms 73 to move in the direction of approaching each other. The two driving arms 73 will drive the two U-shaped plates 74 to move in the direction of approaching each other. The U-shaped plates 74 will drive the anti-skid strips 78 to move when moving. After the anti-skid strips 78 move to a suitable position, they will squeeze the collecting bag 75. With the help of the squeezing of the anti-skid strips 78, the collecting bag 75 will be tightly attached to the surface of the discharge pipe 5. The anti-skid strips 78 can further improve the effect of the U-shaped plates 74 limiting the collecting bag 75. At this time, the collecting bag 75 will be limited on the surface of the discharge pipe 5, and the nicotine raw material discharged from the discharge pipe 5 will fall into the collecting bag 75.
