High-filling wood-plastic composite double-station sliding pelletizing device

Abstract

The invention provides a high-filling wood-plastic composite double-station sliding pelletizing device which comprises an extruding machine, a screw rod, a die head, a sliding plate, a discharging hole, a runner, two support seats, a driving air cylinder, a push rod, a push plate, ejection pins and a pelletizing hole, wherein the die head is mounted at the tail end of the extruding machine; the screw rod is arranged in the extruding machine; the two support seats are fixed on the symmetrical positions of the left and right sides of the die head of the extruding machine; the die head and the discharging hole are fixed between the two support seats; the driving air cylinder is arranged on the support seats and is connected with the push plate through the push rod; and the ejection pins are arranged on the push plate at equal intervals. The high-filling wood-plastic composite double-station sliding pelletizing device utilizes the parallel double-screw extruding machine to mix and extrudehigh-filling wood-plastic composite and is suitable for preparing high-filling wood-plastic composite particles, so that the particles are uniform in texture, high in production efficiency, free of dust, low in water content, stable in quality and low in material oxydative degradation rate.

Description

technical field [0001] The invention relates to the field of granulation devices, in particular to a double-station sliding granulation device for highly filled wood-plastic composite materials. Background technique [0002] Wood-plastic composite material is a new type of composite material that makes full use of agricultural and forestry waste and plastic recycled materials to prepare a dual performance of plastic processing performance and wood texture. As the main raw material of wood-plastic composites, the content of plant fibers is usually as high as 50%. The addition of high-content plant fibers changes the rheological behavior of the resin matrix, resulting in increased viscosity, poor fluidity, and difficult processing. For the production of wood-plastic composite materials for profiles, the plant fiber content is usually as high as 60%. The traditional process is mostly through parallel twin-screw extruder blending and plasticization, and then crushed by a fan to ...
