Abstract
Description

[0001] The utility model relates to the technical field of long fiber reinforced thermoplastic material melt impregnation forming, in particular to a fiber filament uniformly distributed, dispersed, melted and sheared combined device. Background Art
[0002] During the molten impregnation of glass fibers, it was found that during the impregnation process of the glass fibers, when the molten resin and the glass fibers were impregnated through common equipment on the market, it was difficult to fully impregnate the molten resin and the glass fibers, resulting in a poor impregnation effect and ultimately a reduction in the strength of the finished product.
[0003] As those skilled in the art understand, the melt impregnation extrusion technology currently used all adopts a single-screw or twin-screw extrusion grinding head with a special structure. When the pre-tensioned continuous glass fiber bundle passes through this die head filled with high-pressure melt, it is repeatedly subjected to alternating pulling and extrusion, which promotes the forced impregnation of the long fibers and the melt, thereby achieving the purpose of sufficient impregnation. The melt impregnation technology has a high extrusion efficiency and is widely used in industry.
