The invention relates to a glue liquor processing system., which aims to solve the problem that the reasonable addition of silicon dioxide fillers cannot be realized in the prior glue liquor processing system. The invention is additionally provided with a filler stirring cylinder, the input end of the filler stirring cylinder is connected with a filler input pipe and a solvent input pipe, and theoutput end of the filler stirring cylinder is connected with the input ends of a first curing stirring cylinder and a second curing stirring cylinder respectively; and the input end of the filler stirring cylinder is also connected with a resin input pipe, and the arrangement of a low-speed stirring mechanism and a high-speed stirring mechanism in the filler stirring cylinder is recommended. The filler stirring cylinder can be used for adding the silicon dioxide fillers and making the silicon dioxide fillers evenly mixed with a solvent and then a resin glue liquor so as to regulate solid components in the resin glue liquor and improve the uniform distribution of the fillers in the resin.
