The roller assembly comprises a plurality of drum rollers uniformly distributed circumferentially along the outer circumference of the tubular belt. The drum rollers are connected to each other in an axially adjustable manner through a co-directional multi-roller linkage mechanism. The co-directional multi-roller linkage mechanism is connected to the mounting frame through an annular mounting plate, and a deviation correction drive mechanism is connected to the co-directional multi-roller linkage mechanism.
