Rotor structure of pressurized screen of paper machine

The utility model relates to the technical field of paper machines, in particular to a paper machine pressure screen rotor structure which comprises a connecting sleeve and a bearing seat, matching locking blocks are symmetrically welded to the two ends of the connecting sleeve, the number of the matching locking blocks at each end is two, the matching locking blocks are symmetrically arranged on the connecting sleeve, and locking grooves are formed in the matching locking blocks. Arc surface pieces are symmetrically welded to the two sides of the interior of a locking groove, concentric ring grooves are formed in the end faces of the upper end and the lower end of a connecting sleeve correspondingly, two bearing seats are connected to the two ends of the connecting sleeve correspondingly, matching rings are inserted into the concentric ring grooves in an interference fit mode, and the concentricity of the two bearing seats can be guaranteed through the arrangement of the connecting sleeve; in addition, the b
