Grinding fluid paper filter

The invention discloses a grinding fluid paper filter, and belongs to the technical field of grinding fluid filtration. The grinding fluid paper filter comprises a main body frame, a filter paper feeding piece, a clamping and conveying assembly, a squeezing assembly and a driving mechanism. The filter paper feeding piece is arranged on one side of the main body frame and used for installing filter paper, the driving mechanism drives the first clamping and conveying roller and/or the second clamping and conveying roller in the clamping and conveying assembly to rotate, the filter paper is driven to enter the filter tank and enter the wringing roller assembly after passing through the filter tank, and the filter paper filters grinding fluid injected from the top of the filter tank; the filter paper is used for filtering the grinding fluid, metal impurities in the grinding fluid are adsorbed on the surface of the filter paper, the grinding fluid is filtered, and the squeezing assembly squeezes out the grinding f
