Problems solved by technology

[0004] However, for the existing printing method using iron printing technology, it is necessary to use the traditional drying room to treat the surface of the substrate. The drying room consumes a lot of energy, and there is waste gas and waste heat pollution, which has an impact on the environment. Many processes and low efficiency

Embodiment 1

[0020] Such as figure 1 , 2 As shown, the printing method using iron printing machine and environmentally friendly coating in this implementation integrates the laser processor 11 with the traditional iron printing machine. The iron printing machine 1 includes a laser processor 11, a feeding section 12 and a plurality of UV printing units. At the same time, Tinplate with a thickness between 0.12 and 0.40mm is used as the base material, mainly including CC steel grades, large-size rough iron, low tin content or chrome-plated rolled thin steel sheets and secondary cold-rolled thin steel sheets with a thickness of 0.14~0.18mm.

[0021] Wherein, the laser processor 11 is arranged in the feeding section 12 of the iron printing machine 1, and includes a laser generating part for generating a laser beam and a rotating mirror 3 arranged obliquely to reflect the laser beam to the surface of the substrate. The rotating mirror 3 is a polyhedron, The rotation of the rotating mirror 3 is ...

Embodiment 2

[0039] The printing method using iron printing machine and environmental protection coating is the same as in Example 1, wherein the UV ink is made of the following raw materials in parts by weight: 5 parts of fumed white carbon black, 0.5 part of diatomite powder, 25 parts of polyurethane acrylate, polyester acrylate 13 parts, 2 parts of trimethylolpropane triacrylate, 1 part of titanium dioxide, 5 parts of organic pigment, 0.3 part of sodium styrene sulfonate.

[0040] The materials were mixed, heated to 50°C, and stirred for 150 minutes.

Embodiment 3

[0042] The printing method using iron printing machine and environmental protection paint is the same as in Example 1, wherein the UV ink is made of the following raw materials in parts by weight: 10 parts of fumed white carbon black, 1.4 parts of diatomite powder, 28 parts of polyurethane acrylate, polyester acrylate 24 parts, 3 parts of trimethylolpropane triacrylate, 2 parts of titanium dioxide, 10 parts of organic pigments, 0.5 parts of sodium styrene sulfonate.

[0043] The materials were mixed, heated to 56°C, and stirred for 240 minutes.

Abstract

The invention discloses a method for printing by adopting an iron printing machine and an environment-friendly coating. The method is characterized by comprising the steps of substrate surface treatment and UV printing; in substrate surface treatment, the feeding section of the iron printing machine is additionally provided with a laser processor, a substrate surface treatment process is directly built in a printing line to form a continuous online surface treatment and printing production integrated process, and laser produced by the laser processor rapidly moves on a substrate surface; and in UV printing, the iron printing machine is connected in series with a plurality of UV printing units, each UV printing unit comprises a printing assembly, a UV lamp bank and an exhaust gas recovery assembly, the printing assembly in each UV printing unit adopts UV environment-friendly ink to realize printing of local patterns on the substrate surface subjected to laser processing, and each exhaust gas recovery assembly comprises a cooling hood and a suction fan and is used for recovering exhaust gases and waste heat which are generated by UV printing.

Description

technical field [0001] The invention relates to a printing method, in particular to a printing method using an iron printing machine and an environmentally friendly paint. Background technique [0002] Iron printing is to print patterns on tinplate, among which tinplate is a common name for tinplate. Iron printing mainly uses the physical properties of water and ink to repel each other, and with the help of printing pressure, the printing plate is transferred to the tinplate through the blanket. It is used in packaging containers (canning, barrel making and food and beverage packaging), electronic products, It is widely used in various industries such as home appliances, automobiles, and motorcycles. [0003] For example, the Chinese invention patent with the publication number CN103129199A "Iron Printing Processing Technology" and the Chinese invention patent with the publication number CN103122203A "An Inner Layer Iron Printing Coating and Iron Printing Method". The trad...
