Auxiliary coating device for glass fiber composite felt

The invention relates to a coating device, in particular to an auxiliary coating device for a glass fiber composite felt. The auxiliary coating device for the glass fiber composite felt is convenient for coating PTFE emulsion and is uniform in coating. The auxiliary coating device for the glass fiber composite felt comprises a base, a rotating roller, three placing tables, a second mounting frame and a sliding rail, wherein first mounting frames are symmetrically arranged at the top of the base; the rotating roller is rotationally arranged between the two first mounting frames; the three placing tables are uniformly arranged on the rotating roller at intervals; the second mounting frame is arranged on one side of the top of the base; and the sliding rail is arranged at the upper part of the second mounting frame. According to the device, a moving mechanism can drive a coating roller to conduct coating operation, and through cooperation of a clamping mechanism, the rotating roller and the placing tables, autom
