Abstract
The cleaning device (20) for cleaning a cylindrical roller (50), for example an anilox roller of a printing machine, includes a cleaning head (30) with a cleaning chamber (110), in which there is housed a mechanical cleaning member (60), and with which there are associated feeding members (70) for feeding a cleaning liquid into the cleaning chamber (110). The mechanical member (60) and cleaning liquid dispensed by the feeding members work in combination inside said cleaning chamber (110) to clean the lateral surface of the roller (50).
Claims25
A cleaning device for cleaning a cylindrical roller having a longitudinal roller axis and a cylindrical side surface, the cleaning device comprising:
- a cleaning head with a cleaning chamber;
- sealing blades extending parallel to the roller axis and lateral sealing gaskets extending transversely to the roller axis, the sealing blades and the lateral sealing gaskets closing the cleaning chamber, the lateral sealing gaskets having concave edges configured to sealingly contact the cylindrical side surface of the roller;
- a mechanical cleaning member housed in the cleaning chamber;
- a first actuator configured to move the mechanical cleaning member inside the cleaning chamber;
- cleaning liquid feeding members configured to feed a cleaning liquid into the cleaning chamber;
- wherein the mechanical cleaning member and the cleaning liquid fed by said feeding members work in combination inside said cleaning chamber;
- wherein the cleaning head is provided with a translation movement in a direction parallel to the roller axis of the cylindrical roller;
- wherein the first actuator is configured to move the mechanical cleaning member with respect to the cleaning chamber while maintaining the mechanical cleaning member in contact with the cylindrical side surface of the roller.
A cleaning machine comprising:
- a supporting structure;
- on said supporting structure, supporting devices for supporting a cylindrical roller to be cleaned, wherein the cylindrical roller comprises a longitudinal roller axis and a cylindrical side surface;
- a driving unit adapted to drive the roller into rotation when the roller is supported on the supporting devices;
- a cleaning device comprising:
- a cleaning head with a cleaning chamber;
- sealing blades extending parallel to the roller axis and lateral sealing gaskets extending transversely to the roller axis, the sealing blades and the lateral sealing gaskets closing the cleaning chamber, the lateral sealing gaskets having concave edges configured to sealingly contact the cylindrical side surface of the roller;
- a mechanical cleaning member housed in the cleaning chamber;
- a first actuator configured to move the mechanical cleaning member inside the cleaning chamber;
- cleaning liquid feeding members configured to feed a cleaning liquid into the cleaning chamber, wherein the mechanical cleaning member and the cleaning liquid fed by the feeding members work in combination inside the cleaning chamber, the cleaning head being provided with a translation movement in a direction parallel to the roller axis of the cylindrical roller, the first actuator being configured to move the mechanical cleaning member with respect to the cleaning chamber while maintaining the mechanical cleaning member in contact with the cylindrical side surface of the roller.
