The invention relates to a thin film material cutting device. The thin film material cutting device comprises a machine frame with the supporting function, a first roller shaft, first gears, a secondroller shaft and second gears, wherein the first gears are coaxially arranged on the first roller shaft, and the second gears are coaxially arranged on the second roller shaft. According to the thin film material cutting device, before cutting, a thin film material is placed between the first roller shaft and the second roller shaft, the first roller shaft and the second roller shaft rotate so that cutting blades can be matched with annular grooves, and therefore the thin film material can be cut; moreover, the radius of each first gear is smaller than the radius of each second gear, so that the rotating speed of the first roller shaft is higher than the rotating speed of the second roller shaft, that is, the rotating speed of the cutting blades is higher, so that the speed difference between the cutting blades and the thin film material is larger; at the moment, the higher the cutting speed of the cutting blades is, the better the cutting effect of the thin film material is; and therefore the thin film material cutting device can effectively prevent the occurrence of burrs when the thin film material is cut.
