The invention belongs to the technical field of circular knife machine equipment, and provides a portable safe material receiving device for circular knife die cutting equipment. The portable safe material receiving device comprises a rack and further comprises a safety grating, a material receiving roller and a conveyor; a second grating mounting frame is slidably mounted at the discharging end of the rack, and the safety grating is mounted on the grating mounting frame; the material receiving roller is detachably installed at the discharging end of the rack, and when strip-shaped products are produced, the material receiving roller is located between the second grating mounting frame and a die-cutting tool holder; and the conveyor comprises a lower conveying frame and an upper conveyingframe, a stripping knife and a hanging frame are further arranged at one end of the lower conveying frame, when sheet-shaped products are produced, the second grating mounting frame is attached to thedie-cutting tool holder, the conveyor is hung on the discharging side of the die-cutting tool holder through the hanging frame, and the other end of the conveyor penetrates through the second gratingmounting frame. According to the portable safe material receiving device, when conversion production of the strip-shaped products and the sheet-shaped products is carried out, tedious disassembly andassembly of the safety grating are not needed, use is safe, convenient and rapid, the sheet-shaped products are conveyed more orderly and tidily, and the material collecting efficiency is greatly improved.
