Automatic workpiece-blasting machine - has belt forming drums pivoting together about common point

摘要

The workpiece-blasting machine has a troughed belt forming a drum, also loading and unloading stations. The belt (6) forms a number of drums (10-13) one behind the other, the drums pivoting together about a common point, typically the guide roller (7) at the loading station end. For the blasting operation the drums can lie in a common horizontal plane, swinging down to the lower-level discharge conveyor (4) for unloading. There can be holding racks (14) movable up and down between the drums.
