Fiber Reinforced Thermoplastic Composite Double Roll Mixing Equipment

Abstract

Fiber reinforced thermoplastic composite material pair-roller mixing equipment relates to fiber reinforced thermoplastic composite material processing production equipment. A front left panel, a left side panel and a rear left panel of the mixing equipment are fixed on a bottom plate, mixing rollers are longitudinally arranged on the front left panel and the left side panel and a front right panel and a rear right panel; a left middle plate and a right middle plate which are vertically placed are arranged between the left and right mixing rollers. The mixing roller outer wall is a corrugated circular arc structure, and reduces the shear abrasion to enhanced fiber; an intermediate plate can play the role of a scraper; after feeding of the mixing equipment is stopped, a mixed material in the mixing equipment still can flow out, no accumulation of waste material is produced, the waste of raw materials can be reduced; the mixed material can be directly sent to a press for mould pressing production, fiber silk, fiber cloth, fibrofelt and other reinforced materials in various forms can be used, diversified product demands can be met, one machine has multi functions, and the equipment has the advantages of simple structure, convenient maintenance, and effective reduction of the production cost and maintenance cost.

Description

technical field [0001] The invention relates to processing and production equipment for fiber-reinforced thermoplastic composite materials. Background technique [0002] Fiber-reinforced thermoplastic composite materials are widely used in automobiles, electrical appliances, rail transit, construction industries, civil and light industries and other fields due to their excellent characteristics of light weight, high strength, environmental protection and recyclability. [0003] The mixing of reinforcing fibers and thermoplastic resins is an important link in determining the performance of fiber-reinforced thermoplastic composites. At present, more mature mixing equipment includes the D-LFT production line of Coperion W&P in Germany and the LFT-D of Dieffenbacher in Germany. -ILC production line. The cutting and dispersion of reinforcing fibers in the above-mentioned production line and the mixing of fibers and thermoplastic resin are all carried out in the screw extruder, a...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a pair of roller mixing equipment for fiber-reinforced thermoplastic composites, so as to solve the problem of the wear and tear of the existing screw on the strength of the reinforced fibers, resulting in a decrease in the performance of the product; High; when the screw extruder is shut down, there is accumulated material in the barrel, and it is necessary to squeeze out the oxidized and discolored accumulated material when it is re-produced, and it can only be officially produced when new materials come out, resulting in waste of raw materials; Reinforced materials are limited, etc. question
