Manufacturing equipment for coated steel sheets

Abstract

The invention discloses a manufacturing device of a coated steel plate utilizing inkjet printing. The manufacturing device of the coated steel plate according to the embodiment of the present invention comprises the printing device that utilizes inkjet printing to print the surface of the steel plate, and the printing device is alternately arranged with inkjet heads and curing devices in the moving direction of the steel plate on the printing area, The curing device includes a shielding cover for accommodating at least a part of the light beams reflected from the surface of the steel plate to reduce the impact of the light beams irradiated onto the surface of the steel plate from the irradiation portion of the curing device and reflected on ink droplets dropped from adjacent inkjet heads. influences.

Description

technical field [0001] The present invention relates to a manufacturing device of a coated steel plate, and more particularly, to a manufacturing device of a coated steel plate using inkjet printing. Background technique [0002] The steel plate with a pattern printed on the surface can be divided into a printed steel plate using a screen, a printed steel plate using a roll printing machine, and a printed steel plate using a pattern transfer paper. Screen printing steel plate is a printing process carried out on a sheet (sheet) through an intermittent batch type process, rather than on a roll plate. Roller printed steel plate is coated on a roll etched with a printed pattern. The method of ink or paint, pattern transfer paper printing on the steel plate utilizes the method of transferring the transfer paper engraved with the pattern onto the steel plate. [0003] However, the prior art has the following problems. [0004] As far as the screen printing method is concerned, ...

Problems solved by technology

[0004] As far as the screen printing method is concerned, although the manufacturing process is relatively simple, it is necessary to separately manufacture the screen as a printing plate according to the type of pattern or product to be printed, and the number of screens also increases according to the number or type of colors, and finally Resulting in slow operation speed and poor productivity

[0005] In terms of the roll printing method, unlike the screen printing method, the roll printing method is a method of continuously coating a coil and has high productivity, but the printing pattern of the method is simple and various patterns are difficult to achieve, making product design difficult diversification

And, same as the screen printing method, depending on the number of colors, the number of printing rollers will also increase, and the production process is complicated, thereby reducing production efficiency
