Speaking of the cylinder on the surface of the round printing we usually think of screen printing machine, printing rules round face is round surface screen printing machine "professional".
But moving printing machine used for printing cylinder has also been proved to be feasible, the design principle is derived from the principle of curved surface screen printing machine or surface bronzing.Curved surface screen printing machine and surface bronzing machine has an obvious feature is the screen printing or hot stamping version of the press printing or hot stamping in contact with the product is complete, the product in the process of contact with the plate or bronzing version product rotation will happen.Also moving such train of thought to moving printing machine can produce cylinder pad printing machine above.
First we make a fixture.Clamp cylinder can be supported, and screen printing machine fixture, the product will move and move with the fixture.Also need to adjust the pad printing machine's built-in programs make rubber head down come into contact with the cylinder when the product to keep a certain amount of time, until the cylinder products along the under surface of the rubber head for full contact.When the glue head is transferred by molecularly imprinted on the surface, these will be pad printing graphic imprinting to product.
The cylinder pad printing machine principle is simple, but to get the ideal printing we need to make efforts on details.Must first understand how the rubber head shape is most suitable for such transfer ink, what kind of glue head hardness to maintain minimum deformation, and how to make the jig to avoid and cylinder of sliding contact, and how to avoid the glue head lift moment ink drawing.
