Example Embodiment

[0014] As shown in the figure: the composite material pultrusion forming machine, from the head to the tail of the unit, is provided with a yarn feeding mechanism (15), a felt feeding mechanism (16), a fiber weaving platform (3), a thermostatic stainless steel belt composite mechanism, Die worktable (13), traction mechanism (14) and cutting mechanism. The yarn feeding mechanism (15) and the felting yarn feeding mechanism (16) are located at the head of the whole set. The yarn feeding mechanism (15) and the felting yarn feeding mechanism (16) are respectively provided to make the fiber yarn and the fiber felt stretched. Tight state is sent to the next tension yarn release and tension felt release structure. The tension release and tension felt release structure consists of the prestressed damping shaft mechanism arranged vertically on the yarn feeding mechanism (15) and the felt feeding mechanism (16) It is composed of pinwheel shafts which are arranged in one-to-one corresponde...

Abstract

A fiber reinforced thermoplastic composite material direct online pultrusion moulding device belongs to the technical field of composite material pultrusion moulding. The device provided by the invention comprises a yarn supply mechanism, a felt supply mechanism, a fiber braiding platform, a constant temperature stainless steel belt composite mechanism, a thermoplastic pultrusion moulding die anda traction mechanism, wherein the yarn supply mechanism/felt supply yarn cross mechanism is provided with a tension force yarn cross/tension force felt cross mechanism which can be used to tighten fiber yarn/fiber felt and convey the fiber yarn/fiber felt to a subsequent process; the tension force yarn cross/tension force felt cross mechanism is formed by a pre-stress damping shaft mechanism which is vertically arranged on the yarn supply mechanism/felt supply yarn cross mechanism and a connection wheel shaft which is configured corresponding to the pre-stress damping shaft mechanism. Variousreinforced materials can be selected and replaced according to need. One-group or multi-group short stainless steel conveyer belt composite and modularization composite structure can be adopted in the device. The number of fiber and molten polymer composite layers and the fiber configuration can be freely designed. The whole device has a simple structure, is flexibly arranged, requires low production cost, can be used for direct online processing, and is more energy saving and time saving.

Description

technical field [0001] The invention belongs to the technical field of pultrusion molding of composite materials, and relates to equipment for direct online pultrusion molding of fiber-reinforced thermoplastic composite materials. Background technique [0002] Fiber thermoplastic composite materials are currently a hot topic in the development of foreign thermoplastic composite materials. They have the characteristics of light weight, high strength, environmental protection and recyclability, and are widely used in automobiles, electrical appliances, rail transit, construction industries, civil and light industries. [0003] At present, the direct online production of fiber-reinforced thermoplastic composites mainly adopts direct molding and direct injection molding processes, such as the LFT-D-ILC direct molding production line of Dieffenbacher in Germany and the D-LFT system direct injection molding production line of Coperion W&P. . The cutting and dispersing of glass fi...
