Then the cylinder is hoisted and placed on the rotary roller assembly 20, and the cylinder can be rotated in a certain direction by the rotary roller 21; considering that the rotary roller 21 needs to provide sufficient friction to the cylinder to drive it to rotate in a certain direction, the rotary roller 21 in the present embodiment is preferably coated with a rubber layer, which can adopt a rubber-coated roller in the prior art. Through the transversely symmetrical rotary roller assembly, the transversely symmetrical edge pressing roller assembly and the two symmetrically arranged slide rail assemblies, the rotary roller assembly slides along the slide rail assembly according to the size of the cylinder to be welded for adaptive adjustment, and the cylinder is lifted by the rotary roller and rotated.
