Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a drying device for a film printing machine. Background technique [0002] Film printing machine is a kind of equipment that can carry out color printing on the surface of plastic film. After color printing, the plastic film can form characteristic patterns or form information such as the trademark logo of the manufacturer. After the color ink is printed on the film, it must be dried quickly to ensure the uniformity and integrity of the ink on the film. [0003] In response to the above problems, the Chinese patent with the patent announcement number CN207607226U proposes a drying device for a film printing machine, including a workbench, a feed roller and a discharge roller arranged at both ends of the workbench, and successively arranged on the feed roller. and the pretreatment box and the drying box between the discharge roller, a microwave heater is erected on the...

AI Technical Summary

Problems solved by technology

[0004] The above existing technical solutions have the following defects: the film printing machine uses a plurality of transfer rollers in the drying device to form a wave-shaped feeding channel, but at the front end of the drying box, the ink on the film has not yet After being completely dried, the surface of the film printed with ink passes through multiple wavy transfer rollers, which will cause the ink to adhere to the surface of the transfer roller, resulting in poor printing quality of the film
