The invention provides a printing and dyeing device, and belongs to the technical field of machines. The technical problems that when an existing printing and dyeing device is used for printing and dyeing dye paper, the dyed dye paper can not be dried without a drying device, and the production efficiency is low are solved. The printing and dyeing device comprises a rack, a dye box used for containing dyes is fixedly connected to the bottom of the rack, and a drying piece is fixedly connected to the top of the rack. A first driving piece used for driving a printing and dyeing roller to rotate is arranged on the rack, and a guide rail is vertically arranged in the middle of the rack. A sliding block is connected to the guide rail, and the sliding block is fixedly connected with a material pressing roller parallel to the printing and dyeing roller in the axial direction. A second driving piece connected with the sliding block is fixedly connected to the middle of the rack, and the second driving piece can drive the sliding block to move downwards along the guide rail, then enables the material pressing roller and the printing and dyeing roller to be adjacent and enables a printing and dyeing channel to be formed between the material pressing roller and the printing and dyeing roller. The height of the printing and dyeing channel is matched with the thickness of the dye paper needing to be printed and dyed. The printing and dyeing device has the advantages of being high in drying efficiency and good in printing and dyeing effect.
