Embossing device of large-width wallpaper device

Abstract

The invention discloses an embossing device of a large-width wallpaper device. An opposite-pressing rubber covered roller, an embossing roller, an embossing rubber covered roller and a back-pressing steel roller are sequentially installed between wallboards on the two sides. The two ends of the opposite-pressing rubber covered roller are respectively and fixedly connected with a sliding block. Each sliding block is arranged on a guiding rail inside an opposite-pressing rubber covered roller support. The two opposite-pressing rubber covered roller supports are fixed on the wallboards on the two sides respectively. A left embossing oil cylinder is further fixed on each opposite-pressing rubber covered roller support. A piston rod of each left embossing oil cylinder is connected with the sliding block on the same side. The two ends of the embossing rubber covered roller are arranged on the wallboards on the two sides in a sliding mode respectively through an embossing rubber covered roller sliding base. The two ends of the back-pressing steel roller are arranged on the wallboards on the two sides in a sliding mode respectively through a pressed steel roller sliding base. Each pressed steel roller sliding base is connected with a piston rod of a right embossing oil cylinder through a connecting rod. The two right embossing oil cylinders are fixed on the wallboards on the two sides respectively through a set of oil cylinder supports. The embossing device of the large-width wallpaper device is simple in structure and meets the production requirements of large-width wallpaper.

Description

technical field [0001] The invention belongs to the technical field of printing machinery and relates to an embossing device for wide-width wallpaper equipment. Background technique [0002] The embossing device of the current wallpaper production line can generally only produce wallpapers with a width of 530mm and 700mm. This kind of narrow wallpaper requires multiple seams when pasting on the wall due to insufficient width. There will be color difference at the seams, difficulty in matching patterns, and edge warping, which will affect the overall effect of the wallpaper on the wall. [0003] However, if the three-roller counter-pressing or two-roller counter-pressing structure used in the existing narrow-width wallpaper production line is directly applied to the wide-width wallpaper production line, due to the serious uneven distribution of contact pressure and the large deformation of the embossing roller, it will Causes wrinkling of the material film and inconsistent d...
