Extrusion system device for machining reinforced materials

Abstract

The invention provides an extrusion system device for machining reinforced materials. By means of the extrusion system device, a machined product is good in isotonicity, the liquidity of the product in the die pressing process is good, and the load of a threaded rod is reduced. The extruder system device for producing the reinforced materials comprises a twin-screw extruder; the twin-screw extruder comprises a hopper-shaped feeding port; continuous filaments are from a continuous filament supporting rack; part of the continuous filaments enter a fixed-length cutting machine for being subjected to fixed-length cutting, the other part of the continuous filaments are heated through heating equipment, and then the heated continuous filaments and the fixed-length cut filaments enter the twin-screw extruder through the hopper-shaped feeding port to be mixed with and dispersed with thermoplastics polymers. The continuous filaments entering the twin-screw extruder are twisted to broken and dispersed through the threaded rod inside the twin-screw extruder. The continuous filaments twine with one another and are overturned and bent inside the twin-screw extruder, the isotropy of the product is guaranteed, the flatness is good, the liquidity of the product in the die pressing process is increased through the fixed-length cut filaments, the filaments are distributed more uniformly in the product, and the bearing capacity of the produced product is higher.

Description

technical field [0001] The invention relates to the field of processing thermoplastic fiber materials, in particular to an extrusion system device for processing reinforced materials. Background technique [0002] Due to the demand for materials with lighter weight and stronger strength, fiber materials are more and more used in the automotive field, aerospace field, industrial production, civil production and so on. As the market requirements are getting higher and higher, methods, equipment and processes for improving the strength of materials with the same quality are constantly being introduced. The length and degree of dispersion of fibers have a great influence on the mechanical properties of fiber reinforced thermoplastic composites. The longer the fiber, the better the dispersion and the better the mechanical properties. The continuous fiber directly enters the twin-screw extruder, the fiber retains a long length and is not easy to disperse, and the screw twists th...

AI Technical Summary

Problems solved by technology

The continuous fiber directly enters the twin-screw extruder, the fiber retains a long length and is not easy to disperse, and the screw twists the continuous fiber, which increases the burden on the screw, makes the twin-screw screw seriously worn and easily damaged, and needs to be replaced constantly, increasing production costs ; After being cut, it enters the twin-screw extruder, and the fiber is cut by the twin-screw for the second time. The fiber is evenly dispersed but the length is short, which increases the fluidity of the product during the molding process, but reduces the isotropy of the product.
