Anilox roller cleaning machine by laser and procedure for auto-adjusting the laser focal point to the diameter of the anilox roller

An anilox roller cleaning machine comprising:

• a housing including inside:
• an anilox roller supported on a bed having on a first end a first traction roller and a second traction roller, and on a second end a plurality of free rollers;
• a horizontal sliding carriage running parallel to the anilox roller, the horizontal sliding carriage slides through carriage guides powered by a motor;
• a vertical displaceable bracket connected to micrometric axes arranged on the horizontal sliding carriage, the vertical displaceable bracket is driven by a servomotor, the servomotor is operatively connected to an electronic system;
• a multi-laser head connected to the horizontal sliding carriage by the vertical displaceable bracket, the multi-laser head is mounted on a horizontal guide of a first movable support which is connected to the horizontal sliding carriage, the multi-laser head including at least two laser modules, each one of the laser modules including:
• a laser resonator that emits a laser beam having a focal point that is located in a vertical plane equidistant to the axes of rotation of the first and the second traction rollers and the anilox roller;
• a suction device oriented towards the focal point of the laser beam, the suction device including a vertical tube having a flexible hose connected to a first end and a nozzle on a second end;
• a rotation detector device for detecting rotation of the anilox roller, the rotation detector device including a palpate wheel mounted on a second movable support in contact with the anilox roller and connected to an encoder device, which is operatively connected to the electronic system;
• wherein the rotation detector device, in the absence of movement or irregular movement, activates an emergency stop;
• and
• wherein depending on the rotation of the micrometric axes to a right side or a left side, the first movable support and the multi-laser head move up or down.
