Description
Technical Field
The invention relates to the field of machine manufacturing, in particular to a high-filling wood-plastic composite material granulating machine head.
Background
The wood-plastic composite material is a novel composite material which has the double performances of plastic processing performance and wood texture and is prepared by fully utilizing agricultural and forestry wastes and plastic reclaimed materials. The content of the plant fiber serving as a main raw material of the wood-plastic composite material is usually over 50 percent, and the addition of the high-content plant fiber changes the rheological behavior of a resin matrix, increases the viscosity, deteriorates the fluidity and is difficult to process. The content of the plant fiber of the wood-plastic composite material for producing the section is usually as high as 60%, and the conventional process is mainly characterized in that the plant fiber is subjected to blending plasticization by a parallel double-screw extruder and then is crushed by a fan to form a crushed material and the crushed material is used for producing the section. However, the process can cause serious dust loss, seriously affect the production environment and harm the health of production personnel. The wood-plastic composite particles with uniform particles and low ash content are produced in a granulation mode, dust in the production process is reduced, the stability and uniformity of particle feeding in the production process of sectional materials are improved, and the production efficiency and the yield of products are improved. However, the water content of the plant fiber is usually as high as 10%, the drying cost of the plant fiber by heating equipment is too high, and the plant fiber is usually directly used, so that the phenomenon of instability of the wood-plastic composite material in the extrusion granulation process due to excessive water content is caused.
