Technical Field

[0001] The utility model relates to the technical field of carbon fiber processing and molding, in particular to an extrusion molding device. Background Art

[0002] Carbon fiber is a new type of high-strength, high-modulus fiber material with a carbon content of more than 95%. Carbon fiber is composed of graphite flakes composed of condensed polycyclic aromatic hydrocarbons and belongs to a two-dimensional chaotic layer graphite structure. Carbon fiber is lighter than metal aluminum, but stronger than steel, and has the characteristics of high hardness, high strength, light weight, high chemical resistance and high temperature resistance. Carbon fiber has the inherent intrinsic properties of carbon materials and the softness and processability of textile fibers. It is a new generation of reinforcing fiber, which also makes it very popular in aerospace, civil engineering, military, racing and other competitive sports products. Carbon fiber needs to be extruded by an extrusion molding mechanism during the processing process.

[0031] The working principle of the above embodiment is:

[0032] The carbon fiber is placed on the conveyor belt 6, and the conveyor platform body 5 is used to drive the conveyor belt 6 to move.
