The invention provides an automatic oiling system for an aluminum plate. The automatic oiling system comprises a driving roller and a driven roller which are fixedly mounted on an equipment bracket, wherein a driving roller gear is fixedly mounted on a shaft of the driving roller and connected with an alternating current motor; a driven roller gear is fixedly mounted on a shaft of the driven roller and meshed with the driving roller gear; oil spraying pipes are arranged at the upper parts of the driving roller and the driven roller and connected with an oil pump through a pipeline; the oil spraying pipes are fixedly mounted on an oil spraying pipe fixing plate which is fixedly mounted on a linear guide rail; the linear guide rail is fixedly mounted on a linear guide rail fixing plate; an air cylinder fixing seat is arranged on the linear guide rail fixing plate; an air cylinder is mounted on the air cylinder fixing seat; and a guide rod of the air cylinder is connected with the oil spraying pipe fixing plate. The automatic oiling system has a high oiling speed, and pull stretch oil smeared on the aluminum plate is uniform; and the driven roller and the driving roller are oiled indirectly through the oil spraying pipes, so that automatic oiling of the aluminum plate is achieved, the using amount of the pull stretch oil is little, and equipment and ambient environment are not polluted.
