Abstract

The present invention relates to a surface printing machine capable of forming a vivid multicolor printing on the surface of a cylindrical synthetic resin container, the means for surface heat treatment to provide a clear printing surface on the surface of the container continuously fed through the supply means; When the container supply means for supplying the heat-treated container to the printing position, the pint adjusting means for setting the rotation center and the printing reference plane of the supplied container, and the printing reference plane are set, the squeeze is lowered to print the container surface and supply a new container. Ascending printing device head drive means, container conveying means for conveying to the drying apparatus for drying the printed container, and surface drying means for quickly and uniformly drying the surface of the conveyed container to enable multi-color printing. When the container continuously supplied through the supply means reaches the printing position The eccentric cam allows each stroke to be carried out by the eccentric cam, from the adjustment of the focus to provide a clear printing surface, the rotation of the container, and the printing process by lifting and lowering of the printing device as well as the transfer of the printed container. 3 printing device The surface printing layer of the container to be transported is also rapidly dried so that multi-color printing of 2 degrees and 3 degrees can be performed continuously so that constant printing can be always performed without any separate operator's operation.
