[0002] The pressure vessel is composed of a head and a cylinder, and the head needs to be cut, trimmed, welded, and other operations. The heads on the conveyor line are often turned over to adjust the head orientation required by different workstations.

[0003] Common reverse equipment is to turn the head over by using a device that holds the head tightly and then using a rotating device, such as the CN203356932U head rotation displacement device, which buckles the head to the rotating frame and then flips it 360 degrees in the circumference. In addition, the head is also connected to a tensioning unit to prevent the head from being unstable when flipping.
