Description
Technical field
The present invention relates to printing machine anilox roll technical field of surface, more particularly, to a kind of based on plasma spray technology
Printing machine anilox roll preparation method.
Background technology
Flexible version printing has turned into a kind of mode of printing of most vitality in packages printing.For many years, anilox roll is claimed
For " heart " of flexographic printing process, in flexible version printing, anilox roll controls the transfer of ink in printing press, and it is not only controlled
The storage capacity of liquefaction ink, moreover it is possible to make conveying capacity balanced, the final class and uniformity for controlling printing quality.
Traditional anilox roll preparation method is as follows：
Rolling process：Rolling process processing ink cell it is similar with common annular knurl, hobboing cutter body surface face cut forward-reverse spiral line formed and
Raised site corresponding to required anilox roll ink cell.Make hobboing cutter with anilox roll roll body combined pressure to be processed to rolling on lathe,
Can cold rolling complete ink cell processing.
Electronic engraving method：It is similar with the electronic engraving Method And Principle of gravure cylinder.
The process of both approaches is：Roll body preprocessing (material is 45 steel) → electro-coppering (making reticulate pattern layers of copper) →
Before plating post-processing (making roller surface reach the requirement of processing reticulate pattern) processing of → reticulate pattern (rolling or electronic engraving) → chromium plating at degreasing
Manage (enhancing coating adhesion) → chromium plating process (raising anti-wear performance).No. 45 steel of material selection of this method, heavier-weight, electricity
The chromium for plating raw material is Cr VI, and the symptoms such as pneumosclerosis, pulmonary emphysema, nausea, and Cr VI chemical combination occurs after sucking human body
Thing be the plating solution such as carcinogen, copper, hydrochloric acid, sulfuric acid, sodium hydroxide can to artificial into various diseases, prepared by both approaches
Anilox roll is heavier, and pole is not environmentally in process.
Laser engraving method：It is that laser beam is etched processing as power to reticulate pattern roller surface.Anilox roll is in laser
First with the method for plasma spraying by metal oxide (Al before engraving2O3、Cr2O3Or alumina-titanium) it is sprayed on metalling roll surface
Ceramic membrane firmly, fine and close is formed, is then made ceramic vaporization with laser engraving, the high-energy of laser and is formed ink cell.
The process of laser engraving ceramic anilox roller is：The finishing of roll body preprocessing (material is 45 steel) → roll body (reaches roller surface
To ceramic coated requirement) and → spray ceramics → grinding → polishing → laser engraving reticulate pattern (because surface is ceramic layer, its wearability
It is very high).This anilox roll or heavier, although process has abolished the electroplating technology of pole not environmentally, but workhardness is very big
Ceramic material can not be carved using electronic engraving equipment, it is necessary to it is high using laser engraving, cost.Therefore develop a kind of new
The anilox roll preparation method of type has important economic implications.
Thermal spraying is a kind of conventional surface treatment technology of material, can be prepared using heat spraying method in reticulate pattern roller surface
Go out the wear-resisting and excellent coating of corrosion resistance, and thermal spraying has and do not limited by workpiece size and construction site, deposits effect
Rate is higher and the characteristics of heat affecting to matrix material is small, can be not only used for preparing novel anilox roller, is equally useful for useless
The reparation of old anilox roll, integrated cost are relatively low.It is current to complete the whole technology made of anilox roll also not using heat spraying method
Appear in the newspapers, main reasons is that not addressing how also to prepare in reticulate pattern roller surface using heat spraying method equally distributed micro-
Small shrinkage pool or salient point.
Chinese patent CN202370993U is disclosed and a kind of composite roller, including interior tube layer, middle close binder, spray
Coating, interior tube layer are roller matrix or base sleeve；Middle close binder spiral wound and the outer surface for being fixed on interior tube layer；In
Between the outer thermal jet of binder course scribble sprayed coating.Obtained composite roller is made not limited by steel or aluminium-alloy pipe section bar specification
System, the metal of any required size or guiding (or conduction, transmission) roller, anilox roll, the set of ceramic roll surface can be made
Cartridge type anilox roll, it is widely used in printing, packs, weaves, dyeing apparatus or other association areas.Although employ thermal spraying structure
Into sprayed coating, but the composite roller is still without solving the problems, such as how small shrinkage pool or salient point are formed on surface.
The content of the invention
Carved it is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind has with laser
The equal performance of ceramic anilox roller is carved, but technique is relatively easy, energy-conserving and environment-protective, and integrated cost is relatively low based on thermal spraying skill
