Daub sheet automatic segmentation cutting device

The invention relates to the technical field of plaster sheet production, in particular to an automatic plaster sheet segmenting and cutting device which sequentially comprises a segmenting structure and a cutting structure according to working procedures, and a plaster shoveling structure is further arranged between the segmenting structure and the cutting structure. The glue shoveling structure comprises a glue shoveling arm and a driving assembly, the glue shoveling arm reciprocates in the direction perpendicular to the glue moving direction, the driving assembly is used for driving the glue shoveling arm to move back and forth, the bottom end of the glue shoveling arm is connected with a shovel blade, and a reverse jacking assembly is arranged below the shovel blade; the reverse jacking assembly is used for reversely abutting the paper tape on the scraper knife so that the scraper knife can shovel plaster from the edge of the paper tape, through the arrangement of the plaster shoveling structure, redundan
