PROCESS AND EQUIPMENTS

is of an overall translational type, where the tire grabber group
moves up and down along with the guide rail group driven by
the synchronous gear and rack group. The disadvantage of this
structure of manipulator is that it occupies independent space
and the alignment accuracy is difficult to adjust, resulting in
the raw tire being loaded into the steamer eccentrically, which
requires re-adjustment to the correct position, otherwise it
will affect the vulcanization quality of the tire. However, the 1-Synchronous gear and rack assembly; 2-Guide wheel assembly;
