An edge band fine trimming mechanism of an edge banding machine includes a fixed seat, and a lateral feeler wheel, a top feeler wheel set and a scraper, which are disposed on the fixed seat. The lateral feeler wheel is rotatably disposed on the fixed seat. The top feeler wheel set includes a fixing member adjustably disposed on the fixed seat, and first and second top feeler wheels disposed separately, both rotatably disposed on the fixing member and located at a same predetermined height. The scraper is located between the lateral feeler wheel and the top feeler wheel set for trimming an edge of an edge band of a workpiece. Even though the workpiece has a hole, the scraper is positionally maintainable by the top feeler wheel set, that effectively reduces appearance defects of the end edge of the edge band caused in the edge trimming process.
