Continuous fiber glue-dipping system

The utility model discloses a continuous fiber glue-dipping system. The continuous fiber impregnating system is characterized by comprising a glue storage groove, a gradient flow guiding pipe, a glue dipping groove, a recovering groove, a vacuum pump and a fiber expanding and glue-dipping transmission system, wherein the lower part of the glue storage groove is communicated with the glue dipping groove by the gradient flow guiding pipe; a recycling groove is arranged under the glue dipping groove; the fiber expanding and glue-dipping transmission system penetrates through the glue dipping groove to be arranged above the recycling groove; the bottom part of the recycling groove is communicated with the glue storage groove by a flow returning pipe; the glue storage groove is communicated with the vacuum pump by a vacuum pipe; the glue storage groove, the gradient flow guiding pipe and the wall of the glue dipping groove are in a double-layer structure respectively, and a plurality of sections of resistance wires are arranged in the double-layer structures. The continuous fiber glue-dipping system disclosed by the utility model has the advantages that a glue storage area and an glue-dipping area are separated from each other and are connected with each other by a pipeline with temperature gradient, and a fiber positioning device, an expanding device, a glue controlling device and a tension adjusting device are arranged; residual glue can be recycled; the fiber can be fully impregnated and the glue can not be condensed in advance.
