Abstract

The invention proposes production equipment of a continuous fiber thermoplastic prepreg tape, which is used for solving the problems of nonuniform coating, weak infiltration effect and high waste rate in the production process of thermoplastic continuous fibers in the prior art. The production equipment of the continuous fiber thermoplastic prepreg tape comprises two sets of yarn placing racks symmetrically arranged, a tension adjusting device and a preheating dehumidifier, and further comprises a first coating mechanism, a second double-mold head bath infiltration mechanism, a rolling cooling device and a winding device. The production equipment of the continuous fiber thermoplastic prepreg tape infiltrates the internals of fibers through a first coating roller, uses the second double-mold head bath infiltration mechanism for infiltrating the outer surfaces of the fibers, can totally presoak the fibers, and can synchronously guarantee the uniformity of the tape through adjusting a gap between the bath infiltration mechanism and the coating roller.

Description

technical field [0001] The invention belongs to the field of thermoplastic fiber reinforced materials, in particular to a production equipment of continuous fiber thermoplastic prepreg tape. Background technique [0002] With the development of the material industry in recent years, more and more new materials have been used in the fields of automobiles, construction, and engineering instead of traditional metal sheets. They not only have light density, but also have excellent mechanical properties, such as high tensile strength. , bending, high temperature resistance and other excellent properties. In recent years, thermoplastic continuous fiber materials have developed rapidly, and there have been major breakthroughs in technology. The key to the preparation of the material lies in the infiltration of the fiber by the resin, especially for production, it is necessary to be able to produce continuously and ensure the full infiltration of the fiber by the resin.
