[0002] In the traditional dry type light machine, in order to increase the processing efficiency, multiple large barrel structures and multiple small barrels inside them work simultaneously, wherein the large barrel structure rotates around the main rotating shaft, and the large barrel structure drives the small barrels to rotate in a planetary manner, and the overall efficiency is increased by the simultaneous work of multiple small barrels. And in order to ensure that the small barrels are not accidentally opened during work, multiple locking buckles are provided on the small barrels to lock the barrel covers.

[0003] In the traditional dry type light machine, the positioning and opening and closing of the large barrel structure and the small barrels rely on manual operation.

For example, the operator needs to rotate the large barrel structure to the specified position, then manually adjust the small barrels to the opening and closing position, and then open the multiple locking buckles on the small barrels one by one.
