The transfer plate pretreatment device comprises: a driving roller, which comprises a heating layer configured to heat a transfer plate deployed on the driving roller; and a pressing roller, which is configured to press the transfer plate to improve wettability of the transfer plate. ## Claims ### Claim 1 A transfer device, comprising: a transfer plate pretreatment device comprising a driving roller, which comprises a heating layer configured to heat a transfer plate deployed on the driving roller; and a pressing roller, which is configured to press the transfer plate to improve wettability of the transfer plate; a plate cylinder; and a plate-hanging assembly, which is disposed between the transfer plate pretreatment device and the plate cylinder, and configured to hang the transfer plate processed by the transfer plate pretreatment device onto the plate cylinder; wherein the plate-hanging assembly comprises a conveying roller disposed above the driving roller of the transfer plate pretreatment device, and a plate-hanging roller disposed between the plate cylinder and the conveying roller, the conveying roller is configured to convey the transfer plate processed by the transfer plate pretreatment device onto the plate-hanging roller, and the plate-hanging roller is configured to hang the transfer plate onto the plate cylinder. ### Claim 2 (depends on 1) The transfer device according to claim 1, wherein the transfer plate comprises a first base layer and a mesh layer stacked together, the mesh layer being configured to contact a transfer liquid; and the driving roller further comprises a driving roller body, and the heating layer is wrapped on an outer surface of the driving roller body and configured to be attached to and heat the mesh layer. ### Claim 3 (depends on 1) The transfer device according to claim 1, wherein a central axis of the pressing roller is parallel to a central axis of the driving roller; and the pressing roller is movable toward the driving roller to press the transfer plate. ### Claim 4 (depends on 1) The transfer device according to claim 1, wherein two rows of first magnetic holes are disposed on a roller surface of the driving roller, and opposite edges of one surface of the transfer plate are respectively provided with magnetic pins configured to be engaged with the first magnetic holes magnetically. ### Claim 5 (depends on 4) The transfer device according to claim 4, further comprising: a conveyor belt, which is located below the driving roller and configured to convey the transfer plate to be pretreated onto the driving roller. ### Claim 6 (depends on 1) The transfer device according to claim 1, wherein a central axis of the plate-hanging roller is parallel to a central axis of the plate cylinder; and the plate-hanging roller is movable toward the plate cylinder to press the transfer plate while hanging so that the transfer plate is attached to the plate cylinder. ### Claim 7 (depends on 1) The transfer device according to claim 1, wherein two rows of second magnetic holes are disposed on a surface of the plate cylinder, and opposite edges of one surface of the transfer plate are respectively provided with magnetic pins configured to be engaged with the second magnetic holes magnetically. ### Claim 8 (depends on 1) The transfer device according to claim 1, wherein a suction hole is provided on a roller surface of the plate-hanging roller, and configured to suck the transfer plate such that the transfer plate is attached to the plate-hanging roller. ### Claim 9 (depends on 1) The transfer device according to claim 1, further comprising: a detecting assembly and a cleaning assembly which are disposed corresponding to a surface of the plate cylinder, the detecting assembly being configured to detect a foreign matter on the surface of the plate cylinder, and the cleaning assembly being configured to clean the foreign matter on the surface of the plate cylinder. ### Claim 10 (depends on 9) The transfer device according to claim 9, wherein the detecting assembly comprises a light emitting portion and a light receiving portion disposed on opposite sides of the plate cylinder, a connecting line between the light emitting portion and the light receiving portion is parallel to a central axis of the plate cylinder, the light emitting portion is configured to emit detecting light along the surface of the plate cylinder, and the light receiving portion is configured to receive the detecting light. ### Claim 11 (depends on 9) The transfer device according to claim 9, wherein the cleaning assembly comprises a wiping portion and a purging portion, the wiping portion comprises a cleaning roller and a wiper wound on a surface of the cleaning roller, a central axis of the cleaning roller is parallel to a central axis of the plate cylinder, and the cleaning roller is movable along the surface of the plate cylinder, so as to drive the wiper to contact and move along the surface of the plate cylinder; and the purging portion comprises a plurality of nozzles arranged in a direction parallel to the central axis of the plate cylinder and configured to blow toward the surface of the plate cylinder to clean a foreign matter on the surface of the plate cylinder.
