ROTARY TATTOO MACHINE Russian patent published in 2021 - IPC A61M37/00 

FIELD: tattoo industry.

SUBSTANCE: invention relates to the design of a rotary tattoo machine. The machine contains an electric drive located in the housing, which is kinematically connected through the eccentric unit to the connecting rod for its reciprocating movement, the other end of which is connected to the pusher, to which the needle is removably attached with the possibility of reciprocating movement in the guide on which the holder for the hand is fixed. The machine is equipped with a unit for changing the amplitude of the reciprocating movement of the needle by changing the distance between the attachment point of the connecting rod on the pusher and the place where the pusher is attached to the body. The pusher of the reciprocating movement drive is made in the form of an elongated plate, one end of which is hinged on the body for the possibility of swinging this plate relative to the body, and in the body of the plate there is a longitudinal slot along the length of the plate, on one wall of which, along the length of the slot, depressions and protrusions are made for toothed rack formation. The end of the connecting rod, connected to the pusher, through the bearing is seated on an axis, one end of which is made with teeth for engaging with the toothed rack and which is movable in the direction from the toothed rack to move this axis along the toothed rack. An elastically deformable element is placed in the kinematic chain of communication of the electric drive with the pusher for damping the stroke of the needle in contact with the tattooing surface.

EFFECT: invention improves safety and usability.
