Combined apparatus for laser Image transfer printing and lithographic cold stamping

摘要

A combined apparatus for laser image transfer printing and lithographic cold stamping according to the present invention is provided to solve the problems in the prior art that the substrate wobbles when getting in contact with the lower roller and smooth leaving therefrom can be difficult, and that the printing assembly has many parts and therefore a complex structure. The combined apparatus of the invention comprises a frame and mounted thereon a printing assembly, a laminating assembly, a laminated film receiving and releasing assembly, a substrate discharging assembly, a product receiving assembly, a plurality of conveying/holding means and a UV irradiator, wherein the laminating assembly consists of an upper roller and a lower roller, it is characterized in that, said lower roller has sandwich cavities provided inwardly of its arc outer surface, the cavities extend axially and are circumferentially divided into a plurality of air suction or blowing cavities, each of which opens at least on one side and has air holes opened to the arc outer surface of the lower roller, and a covering is provided on the frame to cover the openings of the air suction or blowing cavities, which covering has air suction and blowing orifices each facing the corresponding openings of the air suction or blowing cavities, and that the printing assembly comprises an impression roller, a rubber roller, a plate roller, an anilox roller, and ink supply and homogenizing components.
