Problems solved by technology

However, the following problems still exist in the use of ceramic anilox rollers: the surface of ceramic anilox rollers after laser engraving is relatively rough and needs to be polished
In this way, although a good effect has been achieved in solving the corrosion problem of the metal roll blank, the sealing agent on the ceramic surface layer will interfere with the laser engraving, so that the quality of the engraved mesh is affected, and the mesh is rough, which is easy to cause The mesh is clogged and difficult to clean during use, which directly affects the quality and performance of the ceramic anilox roller

Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with examples.

[0020] A kind of pretreatment method of ceramic anilox roller of the present embodiment comprises the following steps:

[0021] (1) Processing and sanding the metal roll blank;

[0022] (2) Plasma spray the metal bottom layer (nickel-chromium layer) on the surface of the metal roll blank;

[0023] (3) Cool to 80°C, and then evenly apply a sealing agent (such as ROLL-A-CARE Undercorrosion prevention) on the metal bottom layer;

[0024] (4) Spraying the ceramic surface layer on the metal bottom layer that is smeared with sealing agent;

[0025] (5) After finely grinding and polishing the ceramic surface layer, laser engrave mesh holes on the ceramic surface layer;

[0026] (6) Polishing the ceramic anilox roller after laser engraving;

[0027] (7) Perform laser remelting treatment on the surface of the ceramic anilox roller to form a remelting layer. Adjust the energy and ...

Abstract

The invention discloses a post-treatment method for a ceramic reticulated roller, wherein the ceramic reticulated roller undergoes laser carving and surface polishing treatment and then the surface of the ceramic reticulated roller undergoes laser treatment to form a remelting layer. The method strengthens the abrasion resistance of products, thereby greatly putting off the time of grinding lines and improving the service performance and the printing quality of the ceramic reticulated roller.

Description

technical field [0001] The invention relates to equipment parts of a flexographic printing machine and a packaging printing machine, in particular to a method for manufacturing and processing a ceramic anilox roller. Background technique [0002] The anilox roller is the core component of the flexographic printing machine and packaging printing machine. It controls the ink transfer of the printing machine so as to supply the ink to the printing plate accurately and evenly. Therefore, the printing machine has very high performance requirements for the anilox roller. Among them, the mesh of the anilox roller is used as a carrier for ink transfer, and has the function of ink storage and ink distribution. Therefore, the quality of the mesh will affect the storage capacity and transmission capacity of the anilox roller, thereby affecting the grade and consistency of printing quality. sex. Therefore, the quality of the anilox roller and its performance will directly affect the qu...
