AI Technical Summary

Technical Problem

In existing continuous fiber reinforced flame retardant unidirectional prepreg cooling and shaping devices, the equal-height structure of the cooling roller group causes uneven stress on the prepreg in the horizontal direction, which easily leads to displacement or wrinkles, and the cooling efficiency is low.

Method used

By misaligning the cooling rollers, the coolant is concentrated on the side closer to the prepreg, and the cooling roller structure is designed to improve heat exchange efficiency.

Benefits of technology

It eliminates the problem of prepreg misalignment or wrinkles and improves the efficiency of prepreg cooling and shaping.

Abstract

本发明涉及一种连续纤维增强阻燃单向预浸料的冷却定型装置，包括冷却定型装置的机座，机座上设有两组左、右分布的冷却定型辊组，冷却定型辊组包括上、下对称设置的冷却辊，冷却定型辊组内的冷却辊之间设有预浸料，机座左侧的冷却定型辊组低于机座右侧的冷却定型辊组，机座右侧的冷却定型辊组包括右上辊和右下辊，机座左侧的冷却定型辊组包括左上辊和左下辊；所述的左上辊和右下辊均为主动辊，右上辊和左下辊均为从动辊。本装置将冷却辊组错位设置，能消除预浸料偏移或褶皱的问题，同时对冷却辊的结构进行了设计，将冷却液集中设置在靠近预浸料的一侧，来提高换热效率，进而提高预浸料冷却定型的效率。
