How To Maintain The Anilox Roller Reasonably?

The anilox roller is immersed in a tank of an ultrasonic cleaning system filled with a chemical cleaning solution. The frequency converter in the tank sends high-frequency sound waves to crush the dried ink in the mesh holes and flow away with the cleaning liquid. Use ultrasonic cleaning must pay attention: too long cleaning time will lead to the destruction of the net hole. The higher the line number, the shorter the cleaning time.

It is used for ink-jet printing machine of carton manufacturers. The surface of the roller is carved into a pyramid-shaped mesh, and the surface is hard chrome plated. It has high precision, high hardness, long service life, and ensures the uniformity and stability of printing ink. It is ideal for printing equipment to transfer ink. Roll. It can process various anilox rollers within the range of ￠500mmX3000mm according to user needs.

Matching of mixed glue and anilox roller: In order to make the amount of offset printing on the paper and the screen line clear, it is necessary to consider different amounts of glue to adopt a different screen roller, which is often negligent. Generally, the following working principles can be followed. The greater the amount of glue, the less the wire of the screen roller used; the smaller the amount of glue, the more the wire of the screen roller used. Generally, manufacturers can prepare three sets of wire rollers.

Various types of anilox rollers and structures
Judging from the surface structure of the anilox roller body, it is mainly composed of two parts: the mesh hole and the mesh wall; from the composition structure, it is mainly composed of the roller core, the base material and the surface plating layer. The commonly used material of the base material is electroplated copper, which is the basis for making net holes and net walls; the surface plating layer is made of metal chromium or ceramics, mainly to improve the wear resistance and block the corrosion of the base layer copper layer by the solvent.

It can directly process the mesh holes and concave-convex patterns of various lines on the anilox roller surface, without the need for special copper-plated iron walls on the roller surface in advance, long service life, uniform pattern pattern, suitable for compound gluing, coating, ink transfer , Coating and other areas. Mainly used for sizing and coloring. Applicable to industries such as plastic, leather, leather, paper, carton machinery, etc.

The as-cast microstructure of the mirror roll is austenite and a small amount of martensite. The carbides are mainly M7C3 type. The shape is granular, lump, and strip. The distribution is relatively uniform, not a mesh. The macro hardness of this kind of structure is HRC45-50, which has high impact toughness. Microhardness carbide (M7C3) HM1 422-1 813, matrix HM426-467.
