摘要： The novel anilox roller laser cleaning machine consists of a multi-laser head (4) with two or more laser modules (5) that generates two or more contiguous focal points (16), whose separation can be modified by moving the laser modules (5) along a guide (6). It also incorporates a wheel (28) associated with an encoder (21) operatively connected to the electronic system (22) of the machine and, in particular, with the emergency stop system (23). Another novel aspect of the invention refers to a method and means for auto-adjusting the laser focal point (16) to the diameter of the anilox roller (2), wherein the displacement of a second movable support (20) is measured, the atter being proportional to the diameter of the anilox roller (2), said telemetry being received by the electronic system (22) of the machine that extrapolates the distance the multi-laser head (4) have to be moved so that the focal point (16) is located on the surface of the anilox roller (2), by maneuvering the servomotors (11) of micrometric axes (10) to drive the multi-laser head (4) to that position.

摘要： Cleaning procedure for anilox consisting of increasing the diameter of the laser spots (4) above the minimum diameter corresponding to focal spot w0 to a working diameter wN, defocusing the pulses of the laser beam (1) using a lens (3) and at the same time, with the help of a galvo mirror (8), redirecting the laser pulses in an organized manner to the cleaning-active zone (19) such that the laser spots (4) that hit the surface of the anilox (9) partially overlap in the linear direction (11) corresponding to the beam advancement and in the circumferential direction (13) corresponding to the direction of the anilox turn, simulating a continuous pulse.
