In order to achieve the purpose, the technical scheme adopted by the invention is as follows:

a composite fiber resin infiltration method comprises the following steps:

1) the mechanical arm for construction provides traction force for the fiber yarns, the continuous fiber yarns are parallelly guided into the fiber infiltration table after being taken from the fiber yarn tray, and the fiber yarns are subjected to bundling and compounding for construction after being infiltrated with a proper amount of resin on the fiber infiltration table;

2) the fiber soaking table comprises a resin soaking area and a resin recovery area which are adjacent, wherein the resin soaking area is provided with an upper open type resin storage tank, the storage tank is provided with a resin roller, and the lower part of the resin roller is always kept immersed in resin; one side of the resin roller is provided with a quantitative scraper used for controlling the thickness of the resin on the surface of the resin roller; the upper part of the resin recovery area is provided with an open type resin recovery groove, and a fiber tension floating stabilizer and wet fiber guide are arranged above the recovery groove;

3) after entering the resin infiltration area, the parallel fiber filaments contact with the upper surface of the resin roller to infiltrate resin, and simultaneously drive the resin roller to rotate; the fiber filaments soaked with the resin pass through the fiber tension floating stabilizer to maintain stable fiber tension, then pass through wet fiber guide, and finally determine the diameter of the construction composite fiber resin material entering the end of the mechanical arm through bundling and width setting.

In order to introduce the continuous fiber filaments into the resin impregnation zone in parallel, a dry fiber guide is provided at the inlet of the resin impregnation zone, and the continuous parallel fiber filaments enter in parallel from below the dry fiber guide. The dry fiber guide may be a smooth surfaced driven dry roller having a length corresponding to the length of the resin drum to maintain the filaments running parallel to the upper surface of the resin drum.

In order to further control the resin infiltration amount of the fiber yarns, a first fiber guide rod is arranged in front of the quantitative scraper, a second fiber guide rod is arranged on the other side of the resin roller, the parallel fiber yarns which come out from the lower surface of the dry fiber guide rod pass through the lower surface of the first fiber guide rod and then contact with the upper surface of the resin roller, and then pass through the fiber tension floating stabilizer in a mode of passing through the lower surface of the second fiber guide rod in parallel. The first fiber guide rod and the second fiber guide rod are movably connected with the fiber infiltration table, and the resin infiltration area and the contact pressure of the parallel fiber yarns on the surface of the resin roller are controlled by moving the distance between the first fiber guide rod and the resin roller. The first fiber guide rod and the second fiber guide rod are smooth in surface to avoid fiber damage. At the same time, the pressure exerted by the second fiber guide rod on the lower fiber filaments extrudes the excess resin on the fibers.
