Embodiment 1

[0039] see image 3 with Figure 4 , in this embodiment, an improved ceramic anilox roller includes a metal roller body, the surface of the metal roller body is provided with a ceramic surface layer, and the ceramic surface layer is provided with an anilox pattern for loading ink, and the anilox pattern It consists of a plurality of identical and regularly arranged meshes. The cross-sectional shape of the mesh is a stretched hexagon, and the stretched hexagon is obtained by extending the two opposite sides of a regular hexagon to the same length. Hexagon, the stretched hexagon is composed of two stretched sides and four non-stretched sides, and the mesh wall of the mesh includes two stretched walls and four non-stretched walls.

[0040] Further, the distance between the two stretched edges ( figure 2 marked with d1 in ), and the distance from the intersection point of two adjacent non-stretching edges to the intersection point of the other two adjacent non-stretching edges ...

Embodiment 2

[0065] The difference between this embodiment and embodiment 1 is:

[0066] In this embodiment, the distance between the intersection of two adjacent non-stretching sides and the intersection of other two adjacent non-stretching sides is 175 μm. Further, the distance between the two stretched edges ( figure 2 marked with d1 in ), and the distance from the intersection point of two adjacent non-stretching edges to the intersection point of the other two adjacent non-stretching edges ( figure 2 Marked by d2) the ratio is 1:1.4.

[0067] The mesh is provided with two openings, and the two openings respectively pass through the two opposite stretching walls.

[0068] In this embodiment, a method for preparing an improved ceramic anilox roll includes the following steps:

[0069] (1) Get the ceramic anilox roller initial product that surface spraying is coated with ceramic surface layer, adopt laser engraving method to carve out mesh in ceramic surface layer; Wherein, describe...

Embodiment 3

[0082] In this embodiment, the distance between the intersection of two adjacent non-stretching sides and the intersection of other two adjacent non-stretching sides is 205 μm. Further, the distance between the two stretched edges ( figure 2 marked with d1 in ), and the distance from the intersection point of two adjacent non-stretching edges to the intersection point of the other two adjacent non-stretching edges ( figure 2 Marked by d2) the ratio is 1:1.6.

[0083] In this embodiment, a method for preparing an improved ceramic anilox roll includes the following steps:

[0084] (1) Get the ceramic anilox roller initial product that surface spraying is coated with ceramic surface layer, adopt laser engraving method to carve out mesh in ceramic surface layer; Wherein, described laser engraving step comprises:

[0085] A1. Preset the laser engraving speed, pulse frequency, pulse height and duty cycle, change the mesh wall length of the mesh; optimize the engraving program, s...

Abstract

The invention relates to the field of printing, in particular to an improved type ceramic anilox roller and a preparation method thereof. Anilox is arranged on a ceramic surface layer of the ceramic anilox roller and consists of a plurality of meshes which are the same and are arranged regularly, the cross section of each mesh is in the shape of a stretched hexagon, the stretched hexagon is a hexagon which is obtained by lengthening two opposite sides of a regular hexagon by the same length, and the stretched hexagon consists of two stretched sides and four non-stretched sides. When the improved type ceramic anilox roller is used, color difference is not easily caused, a coating quantity is stable, ink blockage is not easily caused, a printing ink covering effect can be improved, printingink transfer performance is good, the printing effect is good, and the meshes are easily cleaned. Compared with a traditional regularly hexagonal anilox roller, the improved type ceramic anilox rollerhas the advantages that the ink loading amount and transfer rate of the improved type ceramic anilox roller are remarkably higher than the ink loading amount and transfer rate of the traditional regularly hexagonal anilox roller under the condition of the same screen, the wear resistance is good, and the service life is long; and the preparation method is simple in process, an operation process is easily controlled, the quality of products is stable, and thus, the improved type ceramic anilox roller is suitable for industrial production.

Description

technical field [0001] The invention relates to the printing field, in particular to an improved ceramic anilox roller and a preparation method thereof. Background technique [0002] Anilox roller is the core component of flexographic printing machine, packaging printing machine, coating machine, glazing machine, etc. It is responsible for uniformly transferring a certain amount of ink to the printing plate, which is very important to the printing effect. Anilox rolls mainly include metal anilox rolls and ceramic anilox rolls. However, metal anilox rollers have poor wear resistance and short service life, making it difficult to engrave into anilox rollers with high line counts. With the development of science and technology, laser engraved ceramic anilox rollers are increasingly replacing chrome-plated anilox rollers and are more widely used. [0003] To ensure accurate reproduction of the meshes of each tonal gradation of the printing plate, each mesh on the printing plat...
