Silk screen roller mechanism of rotary screen printing machine

Abstract

The invention relates to the technical field of printing, and discloses a silk screen roller mechanism of a rotary silk screen printing machine. The silk screen roller mechanism comprises a silk screen roller, a rotary shaft core roller is arranged in the silk screen roller, an ink cavity and a liquid cavity are formed in the shaft core roller, the ink cavity and the liquid cavity are both coaxially formed with the shaft core roller, and a heating plate located between the ink cavity and the liquid cavity is arranged in the shaft core roller. According to the silk screen roller mechanism, flushing liquid is continuously conveyed into an inner liquid pressing tank and an outer liquid collecting tank, and the residue removing effect is improved; besides, the effect of infiltrating printing ink which cannot be removed is achieved, and the situation that the printing ink is used in a traditional printing machine to keep the silk screen roller infiltrated is avoided, so that the loss of the printing ink is reduced, and the printing cost is reduced; and in addition, the problem that meshes of the silk screen roller are blocked due to drying and caking of ink which cannot be removed on the surface of the silk screen roller can be relieved, and the purposes of prolonging the service life of the silk screen roller and improving the printing quality can be achieved.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a screen cylinder mechanism of a rotary screen printing machine. Background technique [0002] Screen printing is a printing method in which the ink on the printing plate is printed on the substrate from the through hole of the plate under the action of the squeegee during printing, which is called screen printing. Among the traditional printing methods, silk screen printing will still dominate and continue to develop. The focus of development is high-precision, high-quality, high-speed, multi-color group, multi-functional, and high-level automatic control screen printing machines. In recent years, screen printing machines have achieved variety diversification, generalization of parts, standardization and serialization of products, and modernization of production management. [0003] The drum type screen generally adopts a metal circular screen, the ink is poured in the drum, ...
