Description
Technical Field
The utility model relates to a ceramic base even water roller for offset press belongs to the technical field of even water roller.
Background
The offset press finishes the operation by the working principle that ink and water repel each other, and the traditional water-homogenizing roller adopts a chrome plating frosted metal roller with relatively high hydrophilicity, so that the frosted surface is abraded after long-term use, the water-homogenizing function is lost, the image-text part of a printed product has uneven color difference, the dot is unsaturated, the plate is pasted, and the blank part has the phenomenon of ink wild, and finally the normal printing cannot be realized.
And after the steel roller is worn, the steel roller is generally repaired by chrome plating after sand blasting, the pores of the roller surface are uneven, the roundness and the straightness of the roller have defects, the recovery is difficult to realize, and the water homogenizing roller is scrapped.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the not enough of above-mentioned prior art, to traditional chromium plating dull polish metal roller expensive and hardly realize repairing the problem of recycling, creatively provided the even water roller of ceramic base for offset press.
In order to achieve the above purpose, the utility model discloses the technical scheme who adopts is:
the ceramic-based water homogenizing roller for the offset press comprises a ceramic-based roller ring and a supporting shaft sleeve or a supporting shaft body arranged in a roller shaft cavity of the ceramic-based roller ring,
the outer surface of the ceramic-based roller ring is provided with hydrophilic micropores arranged in a matrix manner, a separation table is formed between every two adjacent hydrophilic micropores, and the outer surface of the ceramic-based roller ring is a polishing and grinding smooth surface.
Preferably, the hydrophilic micropores include structural grooves having a cross-section of a circle, a triangle, a rectangle, a trapezoid, a rhombus, and a polygon exceeding four sides.
Preferably, the hydrophilic micropores are equihexagonal hydrophilic micropores, and the separation bench intervals between adjacent equihexagonal hydrophilic micropores are equal.
Preferably, the hydrophilic micropores are radium carving-shaped hydrophilic micropores.
Preferably, the ceramic-based roller ring is provided with 500-1200 hydrophilic micropores per inch.
The beneficial effects of the utility model are mainly embodied in that:
1. the ceramic-based water homogenizing roller for replacing the traditional chromium-plated frosted metal roller is innovatively provided, the transfer of ink is greatly improved by utilizing the hydrophilicity of a ceramic-based roller ring and the design of hydrophilic micropores on the ceramic-based roller ring, and the printing density and the printing quality are obviously improved.
2. The ceramic-based water homogenizing roller can meet secondary grinding processing, reduces the maintenance and repair cost of the water homogenizing roller, can ensure that secondary grinding is effective, and cannot cause the condition that the traditional chromium-plated frosted metal roller is repaired and scrapped.
3. The whole design is ingenious, and the implementation, the popularization and the application are easy.

Detailed Description
The utility model provides a even water roller of ceramic base for offset press. The technical solution of the present invention will be described in detail below with reference to the accompanying drawings so as to be easier to understand and grasp.
A ceramic base surge roll for offset press, as shown in fig. 1 to 3, includes ceramic base roller circle 1, and sets up the support axle sleeve or the support axis body in the roller axle intracavity of ceramic base roller circle, thereby support axle sleeve and support axis body and be used for supporting this ceramic base roller circle 1 and realize rotary drive and structural support promptly.
In the present case, the surface 2 of ceramic base roller circle 1 is equipped with the hydrophilic micropore 3 that the matrix was arranged, forms separation platform 4 between the adjacent hydrophilic micropore 3, and the surface of ceramic base roller circle is for polishing and grinding the smooth surface.
Specifically, the ceramic has excellent hydrophilic characteristics, and is formed by designing the hydrophilic micropores 3 and the separation table 4, so that the transfer of ink is greatly improved, the printing density and the quality are obviously improved, in addition, when the ceramic is used for a long time and the roundness is lost due to certain abrasion, the outer surface of the ceramic is polished again, and when the pore space of the hydrophilic micropores 3 is insufficient, the layer surface where the hydrophilic micropores 3 are located is completely polished, and the hydrophilic micropores 3 are processed again to still meet the use requirement.
In one embodiment, the hydrophilic micro-pores 3 comprise structural grooves having a cross-section of a circle, a triangle, a rectangle, a trapezoid, a diamond, and a polygon exceeding four sides. That is, the water homogenizing requirement can be met only by uniformly distributing the hydrophilic micropores 3.
In a preferred embodiment, the hydrophilic micropores 3 are equilateral hydrophilic micropores, and the separation stages 4 between adjacent equilateral hydrophilic micropores are equally spaced. The ceramic-based roller ring is provided with 500-1200 hydrophilic micropores 3 per inch, namely LPI is 500-1200, and the requirement of printing density is met.
In a specific embodiment, the hydrophilic micropores 3 are formed by laser etching, that is, the hydrophilic micropores 3 are formed by laser etching through a laser etching device, in the specific implementation, corresponding hydrophilic micropores 3 are laser etched according to LPI, and after the laser etching is completed, the outer surface 2 is polished and leveled, so that the requirement of roundness is met.
Through the above description, it can be found that the utility model discloses a even water roller of ceramic base for offset press has creatively proposed the even water roller of ceramic base that is used for replacing traditional chromium plating dull polish metal roller, utilizes the hydrophilicity of ceramic base roller circle and hydrophilic micropore design on it, improves the transfer of printing ink by a wide margin, and printing density is showing with the quality and is improving. The ceramic-based water homogenizing roller can meet secondary grinding processing, reduces the maintenance and repair cost of the water homogenizing roller, can ensure that secondary grinding is effective, and cannot cause the condition that the traditional chromium-plated frosted metal roller is repaired and scrapped. The whole design is ingenious, and the implementation, the popularization and the application are easy.
The above technical solutions of the present invention have been fully described, and it should be noted that the present invention is not limited by the above description, and all technical solutions formed by equivalent transformation or equivalent transformation adopted by the spirit of the present invention in the aspects of structure, method or function by those of ordinary skill in the art all fall within the protection scope of the present invention.
