Sublimation printing production line and automated sublimation printing method for cylindrical workpieces

A sublimation printing production line for a workpiece having a cylindrical outer surface includes a sublimation paper loading station, workpiece wrapping station, a baking station, and a sublimation paper dismantling stations. The sublimation paper loading station has a workpiece conveyor belt and a sublimation paper conveyor belt that operate synchronously and in parallel. The sublimation paper is positioned on to an elastic fastening jacket, which is then tightly wrapped around the workpiece with the ends buckled together to secure the sublimation paper to the workpiece and making the sublimation image clearer, more colorful, and ensuring the quality of the sublimation.
