Rotary laser engraving device

A rotary laser engraving device for retaining and rotating objects to be engraved, the rotary laser engraving device comprising:

• a frame, comprising a central bar arranged in a longitudinal direction, a first support post extending vertically upward relative to the central bar, and a second support post extending vertically upward relative to the central bar;
• a first support assembly carried by the first support post and including a first set of rollers for supporting a first end of an object to be engraved;
• a second support assembly carried by the second support post and including a second set of rollers for supporting a second end of the object to be engraved;
• a longitudinal adjustment mechanism carried by the frame and configured to move at least one of the first support post and the second support post in the longitudinal direction along the central bar to vary a longitudinal separation between the first set of rollers and the second set of rollers;
• at least one vertical adjustment mechanism carried by the frame and configured to move at least one of the first support assembly and second support assembly vertically along the first support post and second support post, respectively, to vary a vertical separation between the first set of rollers and the second set of rollers;
• wherein the at least one vertical adjustment mechanism comprises a vertical adjustment mechanism carried by the frame and configured to move the first support assembly along the first support post;
• and
• a motor assembly engageable with the first set of rollers to rotate the first set of rollers to rotate the object to be engraved.

A rotary laser engraving device for retaining and rotating objects to be engraved, the rotary laser engraving device comprising:

• a frame, comprising a central bar arranged in a longitudinal direction, a first support post extending vertically upward and non-longitudinally movable relative to the central bar, and a second support post extending vertically upward and longitudinally movable relative to the central bar;
• a first support assembly carried by the first support post and including a first set of rollers for supporting a first end of an object to be engraved;
• a second support assembly carried by the second support post and including a second set of rollers for supporting a second end of the object to be engraved;
