[0021] There can be multiple storage boxes as needed, all installed on the material discharging rack. Pour the raw materials and auxiliary materials into the storage box, and then feed the raw materials into the dispersion tank through the storage box. The dispersion motor drives the dispersion shaft to rotate, and the dispersion shaft synchronously drives the dispersion blades and dispersion blades to rotate. The dispersion blades break up the raw materials and mix them once. After breaking up, the dispersion blades blow the raw materials into the feed pipe, and then feed them into the mixing tank through the feed pipe. The stirring motor drives the stirring shaft to rotate, and the stirring shaft drives the stirring blades to break up the raw materials entering the stirring tank for secondary mixing. The raw materials after secondary mixing fall into the mixing barrel. The blowing motor drives the mixing shaft to rotate, and the mixing blowing blades blow the secondary mixed raw materials into the lifting barrel through the lifting barrel, and then send them to the ingredient mixing unit; The mixing tank 307 in the mixing unit is tilted in the middle of the mixing frame 301.

The blade spacing of the transverse mixing blade 313 gradually decreases from the input end to the output end; the mixing blade 309 is a spiral-shaped two-section, located in the buffer cylinder 304 and the rotating cylinder 306 respectively. The deadweight tank is mainly used for contact between water mist and powder, and at the same time, the powder falls under its own weight; the mixing drum is used to transfer the wet powder; the vertical mixing blades are used to gradually increase the mixing degree and compactness of the wet powder; the horizontal mixing blades with sparse front and dense back can gradually increase the density of the wet powder; the tilted installation of the mixing tank can reduce the conveying speed of the wet powder and increase the mixing time; The raw material powder is fed into the gravity tank through the powder output pipe. The powder falls by its own weight. As it falls, water is supplied through the water supply pipe. The mixing motor drives the mixing vertical shaft to rotate. The water is dispersed through the water dispersion plate to form water mist that falls. The water mist comes into contact with the powder during the falling process and wets the powder. The wet powder falls into the buffer chamber and is mixed and extruded for the first time by the vertical mixing blades in the buffer chamber. The extruded wet powder falls into the mixing barrel and is mixed and extruded for the second time by the vertical mixing blades in the transfer barrel. After the second mixing, it enters the mixing tank. The transmission motor drives the mixing horizontal axis to rotate, and the mixing horizontal axis drives the horizontal mixing blades to extrude and mix the wet powder after the second mixing again. The powder after the third mixing is discharged through the mixing discharge barrel and enters the extruder. The material is extruded through the extruder head, and the cooling pipe continuously supplies water to the slitting cylinder. After the material strips are extruded, the pelletizing motor drives the pelletizing blades to rotate, and the pelletizing blades shear the material strips. The sheared particles come into contact with and mix with the water in the slitting cylinder. The water cools the particles and prevents them from sticking to each other. After the particles are cut, they are discharged from the mixing output pipe driven by the water flow. The L-shaped mixing output pipe is used to buffer the mixture when it falls, and at the same time, it can also increase the cooling time of the water on the particles. The mixture is guided by the cross wall of the mixing output pipe and falls onto the output guide plate, and then guided by the output guide plate to fall onto the output conveyor belt. The water in the mixture is filtered by the mesh output conveyor belt and falls onto the water collection guide plate for unified collection and discharge. The bamboo fiber particles are driven by the output conveyor belt for output. This solution integrates raw material stirring, mixing, pressing, extrusion and separation, realizing the automatic and continuous production of bamboo-plastic fiber composite materials.
[0022] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any changes made based on the shape and principle of the present invention should be included in the scope of protection of the present invention.
