In the mode of connecting the transmission shaft with the roller through nesting, after the nesting is clamped into one end of the roller, the nesting is connected with the roller through a plurality of radial bolts, and if the fit clearance between the roller and the nesting is smaller, the situation that the nesting is difficult to embed into an inner hole of the roller can occur; if the fit clearance between the roller and the nesting or between the roller and the jacket is larger, the phenomenon that the roller and the nesting are not concentric easily occurs when the roller and the nesting are fixed through a plurality of radial bolts, so that the transmission shaft and the roller are eccentric, the plurality of transmission shafts synchronously rotate, the phenomenon that the heights of the top ends of the plurality of rollers are different can occur, ceramic blanks above the roller easily jump, and even the ceramic blanks can be seriously damaged, thereby influencing the stable conveying of the ceramic blanks. Moreover, when the nesting is connected with the roller, the roller is required to be rotated to fix a plurality of radial bolts, the operation is inconvenient, and the site assembly time for holes and fixing bolts is required to be consumed more.

For this purpose we propose a drive shaft for a ceramic transfer roller.
