Surface printing technology for multi-edge-angle polygonal flexible hose

Abstract

The invention discloses a surface printing technology for a multi-edge-angle polygonal flexible hose. The surface printing technology includes the following steps that (1), a relief printing plate is manufactured and fixed to a printing plate roller of a printing machine through double faced adhesive tape, and rubber blanket and a gasket are fixed to an impression cylinder of the printing machine at the same time; (2), the multi-edge-angle polygonal flexible hose is arranged on a printing core rod in a sleeved mode, and the diameter of the printing core rod is slightly larger than that of the flexible hose, so that the multi-edge-angle polygonal flexible hose is bulged to be a round flexible hose; (3), the machine is started to perform printing, the round flexible hose arranged on the core rod in the sleeved mode is then sent to the position between the printing plate roller and the impression cylinder in the step (1), contact pressure between the printing plate roller and the impression cylinder is adjusted, and therefore it is ensured that oil ink is evenly transferred to the surface of a flexible hose body in a covering mode in the process of printing. The printing technology ensures that the oil ink is evenly transferred to the surface of the multi-edge multi-side hose body in the covering mode.

Description

technical field [0001] The invention relates to a process for printing on the surface of multi-angular and polygonal hoses. Background technique [0002] At present, there are mainly three types of hoses: metal hoses, aluminum-plastic composite hoses, and all-plastic composite hoses. Metal hoses are mainly used in industrial products. Aluminum-plastic composite hoses are mainly used in the packaging of medicines, chemicals, and ointments. The all-plastic composite hose is used in the packaging of cosmetics, food, and medicine. [0003] Since 2000, the cosmetic packaging industry has entered an unprecedented stage of rapid development. Market customers not only pursue the importance of the packaging material itself, but pay more attention to the aesthetics and visual impact of the packaging material. For the design change of the hose, no matter from the printing process or the continuous diversity of the matching cover, the shape characteristics of the circumferential hos...

However, printing graphics and text on a multi-angular surface is a big challenge for the current traditional circular printing machine

Traditional letterpress indirect printing machines and processes can usually only print on flat and circumferential surfaces. Graphics and texts cannot be printed on multi-angular shaped objects, especially the printing quality at the corners of multi-angular shaped objects often cannot be achieved. and smooth surface printing effect
