A high-speed waste cleaning device for a soft trademark cutting machine is used for being matched with a cutting double-cutter set of a double-cutter cutting machine to clean waste materials. The high-speed waste cleaning device is characterized by comprising a fan, a main pipe and a plurality of branch pipes, wherein one end of each branch pipe is communicated with the main pipe, one end of the main pipe is in sealing connection with an air inlet of the fan, the other end of each branch pipe serves as a waste cleaning opening, each branch pipe is provided with a control door capable of being opened and closed automatically close to the communication position between the branch pipe and the main pipe, the two branch pipes on the two sides serve as side pipes, and the cross section of each side pipe is in a rectangular shape. The branch pipes share the waste cleaning main pipe, and the control doors are utilized to periodically collect and send the waste materials to the main pipe to be cleaned when the long-stripe waste materials are cleaned in the branch pipes. Thus, the work efficiency is improved, the product quality is prevented from being affected, and hazards for production safety are avoided.
