Abstract
The invention discloses a pre-treatment method for a ceramic reticulated roller. A sealing agent is applied on a metal bottom layer and is impregnated into the metal bottom layer so as to fill up a gap of the metal bottom layer, thereby preventing corrosion to a metal roller stock from outside and simultaneously avoiding interference of laser carving due to painting of the sealing agent on a ceramic surface in the prior art. The method not only can prevent the corrosion of the metal roller stock but also can guarantee the quality of meshes, and further effectively improves the quality and the service performance of products.
Description
Technical field
The present invention relates to the part of appliance of flexible printing machine, packages printing machine, relate in particular to a kind of manufacturing processing method of ceramic anilox roller.
Background technology
Anilox roll is the core component of flexible printing machine, packages printing machine, and it is controlling the transfer of ink in printing press, so as to printed panel accurately, rationing printing ink, so printing machine equably is very high to the performance requirement of anilox roll.Wherein, the mesh of anilox roll has the effect of Chu Mo and even China ink as the carrier that transmits printing ink, so the quality of mesh quality will influence the storage capacity and the conveying capacity of anilox roll, thereby influences the class and the uniformity of printing quality.Therefore, the quality of anilox roll quality and the quality of serviceability thereof directly have influence on the quality of printed matter.
Ceramic anilox roller is spray metal bottom and a ceramic topcoats on the metal roller stock, goes out mesh with laser engraving then on ceramic topcoats and makes.Because ceramic anilox roller has ceramic abrasive resistance height, advantage that corrosion resistance is strong, characteristics the such as simultaneously China ink of carrying amount is uniform and stable because the mesh that laser engraving goes out has, the printing ink releasability is good in the use, therefore ceramic anilox roller has good application prospects aspect high-quality flexographic printing and the packages printing, gradually the substituted metal anilox roll.But ceramic anilox roller in use still exists following problem: because all there are the space in metal back layer and ceramic topcoats, can not fully metal roller stock and external corrosion environment be kept apart, therefore the metal roller stock in use corrosion can occur, rust staining can appear in roll surface after using a period of time, and then roll surface bubbling and losing efficacy.For this reason, prior art has also been done some improvement to this at present, promptly uses hole sealing agent that ceramic topcoats is carried out sealing of hole and handles, and then ceramic topcoats is carried out laser engraving.Like this, though obtained good effect to solving metal roller stock corrosion problem, but, disturbs the hole sealing agent on ceramic topcoats because can producing laser engraving, feasible mesh quality of carving out is affected, mesh is crude, cause easily in mesh obstruction and the use to be difficult to clean, therefore also directly influenced the quality and the serviceability thereof of ceramic anilox roller.
In addition, the ceramic anilox roller surface behind the laser engraving is all more coarse, need polish again.And polish the melting layer that has formed on the surface when having destroyed laser engraving, thus having reduced its anti-wear performance, the surface easily scrapes lines in the use.Especially packages printing machine, ceramic anilox roller in use can grind lines very soon, thereby has influenced the serviceability and the printing quality of ceramic anilox roller.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of preprocess method of ceramic anilox roller is provided, be intended to prevent the corrosion of metal roller stock, can guarantee the mesh quality again, further effectively improve the quality and the serviceability thereof of product.
Purpose of the present invention is achieved by the following technical programs:
The preprocess method of a kind of ceramic anilox roller provided by the invention may further comprise the steps:
(1) the metal roller stock is processed processing, sanding;
(2) at spray metal, metal roller stock surface bottom;
(3) on metal back layer, evenly smear hole sealing agent;
(4) be coated with ceramic coated surface layer on the metal back layer of hole sealing agent;
(5) after correct grinding, the polishing ceramic topcoats, laser engraving goes out mesh on ceramic topcoats;
(6) polishing is carried out on the ceramic anilox roller surface behind the laser engraving.
The present invention smears hole sealing agent on metal back layer, hole sealing agent is penetrated into metal back layer and has filled up its space, thereby stoped outside corrosion, avoided prior art again because the interference that hole sealing agent spreads upon on the ceramic topcoats to be produced simultaneously laser engraving to the metal roller stock.
The present invention can take following further measure: the metal roller stock that will spray metal back layer in the described step (3) is cooled to 78 ℃～82 ℃, is advisable with 80 ℃, evenly smears hole sealing agent then on metal back layer.
In addition, carry out again the surface of ceramic anilox roller being carried out laser treatment and being formed remelted layer after described step (6) finishes polishing to the ceramic anilox roller surface.The present invention adopts the laser remolten technology, and energy, spot size according to actual anilox roll line number adjustment laser to guarantee roll surface remelting effect, do not damage the mesh of having carved simultaneously again., strengthened the anti-wear performance of product, thereby postponed greatly the time that grinds lines at the remelted layer that the ceramic anilox roller surface forms through laser treatment.
The present invention has following beneficial effect:
(1) can effectively stop the corrosion of external environment condition, prevent the roll surface bubbling and lost efficacy the metal roller stock; The interference that can avoid simultaneously prior art to be produced to laser engraving owing to hole sealing agent is coated on the ceramic topcoats, thus the mesh quality guaranteed, and also roll surface is easy to clean.
(2) surface of the ceramic anilox roller after polishing is adopted the laser remolten technology and is formed remelted layer, has strengthened its anti-wear performance, thereby has postponed the time that grinds lines greatly, has improved the serviceability and the printing quality of ceramic anilox roller.
The specific embodiment
The present invention is described in further detail below in conjunction with embodiment.
The preprocess method of a kind of ceramic anilox roller of present embodiment may further comprise the steps:
(1) the metal roller stock is processed processing, sanding;
(2) at metal roller stock surface plasma spray metal bottom (nicr layer);
(3) be cooled to 80 ℃, on metal back layer, evenly smear hole sealing agent (as ROLL-A-CAREUndercorrosion prevention) then;
(4) be coated with ceramic coated surface layer on the metal back layer of hole sealing agent;
(5) after correct grinding, the polishing ceramic topcoats, laser engraving goes out mesh on ceramic topcoats;
(6) ceramic anilox roller behind the laser engraving is carried out polishing;
(7) laser remolten being carried out on the ceramic anilox roller surface handles and the formation remelted layer.Adjust energy, the spot size of laser according to actual anilox roll line number.For the ceramic anilox roller of 300 lines, adopt following remelting parameter: 58 microns of pitch, 201 microns of some distances, speed 55RPM, frequency 3060,6 of pulses, blow gas pressure 2KG.
