The slitting device comprises two opposite fixed plates, a first transmission guide wheel, a cutter groove wheel transmission shaft and a slitting shaft which are parallel are arranged between the two fixed plates, the first transmission guide wheel and the cutter groove wheel transmission shaft are the same in height,the slitting shaft is arranged above the cutter groove wheel transmission shaft, cutter groove wheels are arranged at the two ends of the cutter groove wheel transmission shaft, and are arranged on the cutter groove wheel transmission shaft in a sleeving manner, multiple grooves are formed in the cutter groove wheel transmission shaft, and the cutter groove wheels are clamped in the grooves; twocutter rests are arranged on the slitting shaft in a sleeving manner, and a slitting cutter is arranged on each cutter rest in an erected manner. The cutter groove wheels arranged on the cutter groovewheel transmission shaft in a sleeving manner are used, the cutter groove wheels can support the edge of the thin film, the phenomenon that the edge of the thin film is suspended is avoided, it is ensured that a cutter can cut into the edge portion of the film, the cutter sliding phenomenon can be avoided, narrow edge can be cut, and thin film waste is reduced.
