In the present invention, unless otherwise clearly defined and defined, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0023] like Figure 1 As shown, the flexible kneading device for recycling defective cigarette shreds is installed on the vibrating screening device 100, including a bracket 1, an air motor 2 and a kneading mechanism 3. The kneading mechanism 3 is driven to rotate by the air motor 2. The bracket 1 is fixed to the base on the side of the vibrating screening device 100 by screws. The air motor 3 is detachably connected to the bracket 1 by screws. The kneading mechanism 3 is located directly above the screen plate 101 of the vibrating screening device 100.

[0024] The air inlet end of the pneumatic motor 2 is equipped with a quick-connect air pipe connector 21. The high-pressure air pipe is connected to the quick-connect air pipe connector 21 after passing through a pressure regulating valve (not shown in the figure). The pressure regulating valve can realize stepless speed change of the pneumatic motor 2. As long as the opening of the pressure regulating valve is controlled, that is, the flow rate of compressed air is controlled, the output power and speed of the motor can be adjusted. The air source in the factory can be directly connected to the high-pressure air pipe. The pneumatic motor can be selected to have stepless speed change, and the kneading intensity can be adjusted according to the on-site conditions, and the adjustment is convenient. The pneumatic motor has an overload protection function and will not fail due to overload. It has a high starting torque and can be started directly with load, and the starting and stopping are both quick.

[0025] like Figure 2As shown, the kneading mechanism 3 includes a three-pronged rotating shaft, a vertical silicone rod 32 and a V-shaped silicone rod 31. The upper end of the three-pronged rotating shaft has a vertical input shaft 35, and the lower end has three vertical output shafts with coplanar axes and equal spacing. The vertical input shaft 35 is connected to the output end of the pneumatic motor 2. Among the three vertical output shafts, the lower end of the middle output shaft 34 is sleeved with the V-shaped silicone rod 31, and the output shafts 33 on both sides are sleeved with the vertical silicone rod 32 respectively. A gap is formed between the vertical silicone rod 32 and the V-shaped silicone rod 31 and the surface of the sieve plate 101. The setting of the gap height needs not to interfere with the beating of the vibrating screen and can fully knead the cut defective cigarettes. The output end of the pneumatic motor 2 is connected to the three-pronged rotating shaft through a coupling, and the vertical input shaft 35 of the three-pronged rotating shaft is divided into two sections, which are connected by a locking nut 4. The size of the gap between the vertical silicone rod 32 and the V-shaped silicone rod 31 and the surface of the sieve plate 101 can be adjusted by the locking nut 4.

[0026] Specifically, the center point of the V-shaped silicone rod 31 is located on the center line of the intermediate output shaft 34. The V-shaped silicone rod 31 has at least two cylindrical side arms, which extend upward and outward along the center point, and the inclination angle of the cylindrical side arms to the horizontal plane is 12°. The vertical input shaft 35 is colinear with the axis of the intermediate output shaft 34. The vertical silicone rod 32 is a cylinder. Using the principle that the vertical silicone rod 32 and the V-shaped silicone rod 31 are coaxially driven, the rotation trajectory diameters are different, the angular velocity is the same, but the linear velocity is different, the V-shaped silicone rod 31 rotates to flexibly rub the paper flowers, and the cylindrical side arms of the V-shaped silicone rod 31 have a higher linear velocity relative to the center, which rubs and pulls the defective cigarettes to bring out the tobacco inside. The inclined setting of the cylindrical side arms makes it easier for the cylindrical side arms to bring out the tobacco. The V-shaped silicone rod 31 transports part of the paper flowers to the surroundings and part to the end of the vibrating screen. The cigarettes sent to the surroundings are further kneaded by the vertical silicone rods. The speed of the vertical silicone rods conveying the paper flowers is faster than that of the V-shaped silicone rods. Therefore, most of the paper flowers are kneaded and conveyed by the inclined silicone rods and the vertical silicone rods, and the tobacco shreds entrained in the cut cigarettes are taken out. The cigarettes sent to the surroundings by the V-shaped silicone rods 31 are easily blocked by the accumulation on both sides of the screen plate 101. The vertical silicone rods knead them and send them to the end of the vibrating screen for transportation, ensuring smooth transportation on the vibrating screen. Due to the characteristics of the silicone rod material, it will not cause damage to the tobacco shreds, so that there is no tobacco shreds in the separated paper flowers, reducing waste.

[0027] like Figure 3 As shown, the number of cylindrical side arms of the V-shaped silicone rod 31 can be 2, 3 or 4, and they are evenly distributed in the horizontal circumferential direction with the center point as the center of the circle. The number of cylindrical side arms is determined according to the actual tobacco separation effect for different cigarettes. Blind holes are provided on the V-shaped silicone rod and the vertical silicone rod, and they are connected to the vertical output shaft through the blind holes. When installing, lubricant can be applied in the blind holes to conveniently tighten it on the vertical output shaft, which is convenient for replacing the silicone rod.

[0028] The above are only preferred embodiments of the present invention, which are only illustrative and not restrictive. The structures and connection modes of the components in the present invention can be changed, and any equivalent transformations and improvements based on the technical solution of the present invention should not be excluded from the protection scope of the present invention.
