Embodiment Construction

[0034] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0035] Such as Figure 2~3 As shown, the melt feeding device 43 includes a main channel 4301, and the main channel 4301 communicates with the first-level sub-runner 4302, the second-level sub-runner 4303, and the third-level sub-runner 4304 in turn, and the first-level sub-runner 4301 is separated from the main channel 4301. Distributed in parallel along the main channel 4301. The diameter of the main channel 4301 gradually becomes smaller along the melt flow direction, and the diameter change mode can be gradual or gradually decreasing. In this embodiment, the main channel 4301 is divided into multiple sections, and the diameter of each section decreases. The diameter of the latter section of the direction decreases by 2% to 20% relative to the diameter of the previous section, and the transition between adjacent sections is connected by a transition c...

Abstract

The invention relates to a melt feeding device, and a device and a method for forming continuous fiber reinforced thermoplastic impregnated belts, and belongs to the technical field of the preparation of continuous fiber reinforced thermoplastic resin composites. The melt feeding device comprises a main runner which is orderly communicated with primary sub-runners, secondary sub-runners and third-stage sub-runners; the primary sub-runners are divided from the main runner and distributed in parallel in parallel with one another along the main runner; the device for forming the continuous fiber reinforced thermoplastic impregnated belts comprises an impregnation unit in which the melt feeding device and impregnation rollers are arranged, wherein the first pushing impregnation roller in the feeding direction is arranged right above the main runner of the melt feeding device; the method for forming the continuous fiber reinforced thermoplastic impregnated belt comprises the steps of preheating pre-dispersing, preheating tensioning, impregnating, lustering, cooling, collecting and the like. The melt feeding device and the device for forming the continuous fiber reinforced thermoplastic impregnated belts are simple in structure; besides, the fiber preheating speed is high, the fiber preheating efficiency is high, the melt flowing resistance and the melt heating time are reduced, and the fiber wetting effect of the impregnated belts is excellent.

Description

technical field [0001] The invention relates to a melt feeding device, a continuous fiber-reinforced thermoplastic impregnated belt molding device and a method, and belongs to the technical field of preparation of continuous fiber-reinforced thermoplastic resin-based composite materials. Background technique [0002] Continuous Fiber Reinforced Thermoplastic Composite CFRTP is a new type of composite material with high strength, high rigidity and high toughness manufactured by special process with continuous fiber as reinforcement material and thermoplastic resin as matrix. Since the reinforcing fibers of CFRTP are continuous, its mechanical properties are much higher than those of long-fiber and short-fiber reinforced thermoplastic composites. [0003] Continuous fiber-reinforced thermoplastic resin-based impregnated tape is a tape-shaped semi-finished product or product made by fully impregnating continuous fibers with thermoplastic resin compounds using a proprietary proc...
