A mixing cylinder 4 is fixedly connected to the top of the inner cavity of the granulating cylinder 3;

[0031] A granulating assembly is arranged in the inner cavity of the granulating cylinder 3.

A movable sleeve 8 is movably connected to the surface of the rotating rod 7. Pressing rollers 9 are movably connected to both sides of the surface of the movable sleeve 8. A mixing member is arranged in the inner cavity of the mixing cylinder 4;

[0032] A grain taking assembly is arranged at the bottom of the inner cavity of the granulating cylinder 3. The grain taking assembly includes a cylinder 10 which is fixedly connected to both sides of the top of the base 1. The top of the cylinder 10 is fixedly connected to a top plate 11.

[0033] Specifically: The top of the base 1 and the fixing frame 2 are connected by three columns. The fixing frame 2 is annular, and its inner cavity is fixedly connected to the outer surface of one side of the granulating cylinder 3. Half of the surface of the mixing cylinder 4 is located in the inner cavity of the granulating cylinder 3, and the other half is located outside the granulating cylinder 3;

[0034] Protruding blocks are fixedly connected to the outer surface of the die cylinder 6, and the surface of the protruding blocks is movably connected to the surface of the limiting ring 5, so that the die cylinder 6 can rotate in the inner cavity of the granulating cylinder 3. Bearings are movably connected to both sides of the surface of the movable sleeve 8. One end of each bearing is fixedly connected to a pressing roller 9, and the other end of the pressing roller 9 is rotatably connected to the inner wall of the granulating cylinder 3 through a bearing. The pressing roller 9 can compact the lignin fiber falling on the surface of the die cylinder 6 and evenly lay it in the die groove 21. When the top of the storage plate 13 contacts the bottom of the die cylinder 6, the top of the top plate 11 contacts the top of the inner cavity of the storage plate 13, and the stretching distance of the pulling spring 12 reaches the maximum. The cooling block 14 can cool the surface of the top plate 11, so that the lignin fiber particles are quickly formed. Specific Embodiment Two

[0036] Please refer to Figures 1-5, on the basis of the first specific embodiment, the mixing member includes a motor 15, the motor 15 is fixedly connected to the top of the mixing cylinder 4, the output end of the motor 15 is fixedly connected with a stirring rod 16, and both sides of the surface of the stirring rod 16 are fixedly connected with stirring blades 17. Both sides of the bottom of the inner cavity of the mixing cylinder 4 are communicated with a lower liquid pipe 18, and a solenoid valve 19 is sleeved on the surface of the lower liquid pipe 18. A heating block 20 is fixedly connected to the top of one side of the mixing cylinder 4. A mold groove 21 is formed in the inner cavity of the mold cylinder 6, and the surface of the pressing roller 9 is movably connected to the top of the inner cavity of the mold groove 21. The bottom of the inner cavity of the mold groove 21 extends to the outside of the mold cylinder 6. Circular holes are formed on both sides of the bottom of the inner cavity of the storage tray 13, and one side of the surface of the cylinder 10 is slidably connected to the inner cavity of the circular hole. The bottom end of the stirring rod 16 extends to the outside of the mixing cylinder 4, and one side of the surface of the stirring rod 16 is rotatably connected to the bottom of the inner cavity of the mixing cylinder 4 through a bearing. The bottom end of the stirring rod 16 is fixed to the top end of the rotating rod 7. A storage opening is formed in the top of the inner cavity of the storage tray 13, and the surface of the top plate 11 is slidably connected to the inner cavity of the storage opening. A circular groove is formed in the bottom of the inner cavity of the granulation cylinder 3, and the surface of the storage tray 13 is slidably connected to the inner cavity of the granulation cylinder 3 through the inner cavity of the circular groove.

[0037] Specifically: the output end of the motor 15 extends into the inner cavity of the mixing cylinder 4. The top end of the stirring rod 16 is fixed to the output end of the motor 15, and the bottom end extends to the outside of the mixing cylinder 4 and is fixed to the top end of the rotating rod 7. There are five stirring blades 17 in total, and their lengths are different to adapt to the shape of the inner cavity of the mixing cylinder 4. The lower liquid pipe 18 can discharge the mixed lignin fibers to the surface of the mold cylinder 6 through the solenoid valve 19 on its surface. And by rotating the mold cylinder 6, the lignin can be evenly laid in the mold groove 21. The heating block 20 can heat the inside of the mixing cylinder 4 to increase the plasticity of the lignin.

[0038] When the mold cylinder 6 rotates, the pressing roller 9 moves in a circular motion at the top of the inner cavity of the mold groove 21 in the inner cavity of the mold cylinder 6, so as to press the lignin and make the lignin uniform. A sealing ring is sleeved between the inner cavity of the circular hole and one side of the surface of the cylinder 10 to prevent the formed particles from leaking when the cylinder 10 moves. The storage opening allows there to be a certain gap between the top plate 11 and the inner cavity of the storage tray 13, so as to facilitate the storage of particles. And during molding, the top of the top plate 11 contacts the bottom of the inner cavity of the mold groove 21, so that the lignin can be quickly formed and the liquid lignin will not leak out. The storage tray 13 moves out of the granulation cylinder 3 through the circular groove to facilitate the removal of the particles. One side of the inner cavity of the mixing cylinder 4 is communicated with a feed pipe.

[0039] The working principle of the present utility model is as follows: when granulating lignin fibers, first introduce the lignin raw material into the inner cavity of the mixing cylinder 4 through the feed pipe, and then start the motor 15. The motor 15 drives the stirring rod 16 to rotate. The stirring rod 16 drives the stirring blades 17 and the rotating rod 7 to rotate. The stirring blades 17 evenly mix the lignin fibers and additives in the mixing cylinder 4, and heat them through the heating block 20 to increase the plasticity of the lignin.

[0040] When the lignin inside the mixing cylinder 4 is mixed to a certain extent, the solenoid valve 19 can be opened to introduce the lignin raw material onto the surface of the mold cylinder 6. When the stirring rod 16 rotates, it will drive the rotating rod 7 to rotate, and the rotating rod 7 drives the mold cylinder 6 to rotate, so that the lignin can be evenly introduced into the mold grooves 21 inside the mold cylinder 6. When the mold cylinder 6 rotates, the pressing roller 9 will compact the lignin on the surface of the mold cylinder 6 and make the lignin evenly distributed in each mold groove 21. Then, by turning on the cooling block 14, the temperature on the surface of the top plate 11 drops, so that the lignin particles in the mold grooves 21 are quickly formed, and thus the granulation of lignin fibers can be completed;

[0041] When the granulation is completed and the particles need to be taken out, first start the cylinder 10. The cylinder 10 drives the top plate 11 to move. Two sides at the bottom of the top plate 11 are fixedly connected with tension springs 12, so that at this time the top plate 11 moves inside the inner cavity of the storage plate 13, thereby making the inner cavity of the storage port inside the inner cavity of the storage plate 13 larger, and the formed particles can fall into the storage plate 13. When the elasticity of the tension spring 12 reaches a certain degree, the downward movement of the cylinder 10 can drive the storage plate 13 to move together, so as to move the storage plate 13 out of the granulation cylinder 3, and the formed particles can be taken out to facilitate the next sieving work.

[0042] The standard parts used in the present utility model can all be purchased from the market, and can also be customized according to the description of the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, welding, etc. that are mature in the prior art.
