The invention discloses a sheet jelly cutting system and relates to the technical field of sheet jelly and Chinese vermicelli production and manufacturing equipment. The system comprises a bracket, acutting device and a power device. The bracket comprises a conveying device, a first roller and a second roller. The first roller is far away from the conveying device in the horizontal direction relative to the second roller, and a guide belt is formed at the interval of the first roller and the second roller in the horizontal direction. The first roller and the second roller rotate in opposite directions. The cutting device comprises a fixed cutter and a movable cutter. The fixed cutter is positioned below the guide belt and comprises a fixing part and a cutting part arranged at the edge ofthe fixing part. The movable cutter comprises a rotating part, cutting knives and a separating module. Each cutting knife comprises a connecting part detachably connected with the rotating part and astraight-line cutting edge extending outward from the connecting part. The cutting part comprises cutting ribs parallel to the axes of the first roller and the second roller, and the circular track formed by the rotation of the edges of the cutting edges is tangent to the cutting ribs. Through the sheet jelly cutting system, sheet jellies can be effectively cut, and meanwhile the adhered cutters and the sheet jellies can be separated quickly and conveniently after the sheet jellies are cut.
