Multi-station functional position confirmation method and shading device for curved surface printing

Abstract

The invention relates to a curved surface printing multi-station function location determining method and a shading device. The curved surface printing multi-station function location determining method and the shading device are characterized in that a lighting trap supporting frame, a lamp box and a lighting trap device are provided; the lamp box is fixed on the lighting trap supporting frame; and the UV lighting trap device consists of a lighting trap inside arc-shaped plate, a lighting trap outside arc-shaped plate and a lighting trap bottom arc-shaped plate, and the three plates form a shading arc-shaped channel with the two sides and the front side opened and the rear side fully closed. According to the length of the shading arc-shaped channel, the operation shading station refers to that more than one station distance is covered with the left side and the right side of the curing station serving as a core, and the distance between the lighting station and the curing station is prolonged to the maximum degree after lighting, so that other function stations can be assembled, the method and the device are convenient to operate, the UV curing light is covered, and high printing quality and good lighting effect are achieved.

Description

Technical field [0001] The invention relates to a printing machine, in particular to a curved surface printing multi-station functional position confirmation method and a shading device for printing patterns and characters on a curved surface and then varnishing to enhance the brightness of the printed matter. Background technique [0002] Existing domestic and foreign cylindrical curved surface printing stations, the printing station glazing adopts channel curing or box-type thermal curing, instead of using step indexing turntable to complete the graphic printing at one time, UV curing and simultaneous glazing and then curing The technology, and there is no position curing hood. The production process is backward and the efficiency is poor. Although the sixteen-station curved printing machine of the present inventor has made innovations, due to the small distance between the stations, the shading arc channel is not used after graphic printing and coating printing. As a result, ...

AI Technical Summary

Problems solved by technology

Its production technology is backward and the efficiency is poor. Although the inventor's sixteen-station curved surface printing machine has been innovated, due to the small distance between each station, no light-shielding arc channel is used after graphic printing and glazing printing. As a result, the UV radiation affects the transfer image skin, glazing roller and other stations on both sides, thus affecting the printing quality and glazing effect. At the same time, the distance from the glazing station to the curing station is too short to install other functional devices. , especially the UV light problem is not only unsafe but also inconvenient to operate
