the specific embodiment:
For the ease of those skilled in the art's understanding, below in conjunction with embodiment and 1 ~ 3 pair of the utility model of accompanying drawing, be further described, the content that embodiment is mentioned is not to restriction of the present utility model.
See Fig. 1 ~ 3, a kind of roller for laser paper printing, comprise roll body 1, roll body 1 surface is provided with non-printing zone 2 and printing zone 3, non-printing zone 32 surfaces are fixedly connected with copper plate 4, printing zone 3 surfaces offer laser engraving layer 5, copper plate 4 and laser engraving layer 5 surface are all fixedly connected with chromium coating 6, laser engraving layer 5 comprises that the engraving screen density of engraving screen density, engraving net angle and second carving layer 52 of the first carving layer 51 and the second carving layer 52, the first carving layers 51, engraving net angle are all not identical.When the engraving screen density of the first carving layer 51 is 80 lines, engraving net angle while being 37 °, the engraving screen density of the second carving layer 52 is that 105 lines, engraving net angle are 40 °; When the engraving screen density of the first carving layer 51 is 70 lines, engraving net angle while being 37 °, the engraving screen density of the second carving layer 52 is that 100 lines, engraving net angle are 40 °; When the engraving screen density of the first carving layer 51 is 60 lines, engraving net angle while being 37 °, the engraving screen density of the second carving layer 52 is that 86 lines, engraving net angle are 40 °.
Roller of the present utility model adopts all not identical the first carving layer 51 and the second carving layers 52 of engraving screen density and engraving net angle, tomography problem in the time of can solving by the mode of gravure the printing of level version, by the overlapping printing of the first carving layer 51 and the second carving layer 52, make position of fault press mutually dislocation, thereby it is naturally mild to reach printing level, printing efficiency is high, and production cost is low.The utility model is simple in structure, easy to process, cost is low, practical.
In the present embodiment, described roll body 1 is the roll body 1 of being made by metal material.For making the utility model reach best result of use, described roll body 1 is the roll body 1 of being made by seamless steel pipe.Seamless steel pipe be a kind ofly there is hollow section, periphery does not have jointed circle, square or rectangle steel.Seamless steel pipe is to make hollow billet with steel ingot or the solid pipe hole that wears long, and then through hot rolling, cold rolling or cold group, makes.Seamless steel pipe has hollow section, a large amount of pipelines as carrying fluid, steel pipe is compared with solid steel such as round steel, when bending resistance torsional strength is identical, weight is lighter, be a kind of Economic Section steel, be widely used in manufacturing structure part and machine components, as steel scaffold of using in oil drill rocker, truck drive shaft, bicycle rack and construction etc.
In the present embodiment, the inside of described roll body 1 is hollow-core construction, hollow-core construction the weight that can alleviate roll body 1 is set, convenient carrying.
In the present embodiment, the wall thickness of described roll body 1 is 10 ~ 100mm.For making the utility model reach best result of use, the wall thickness of roll body 1 is 20 ~ 70mm.When the wall thickness of roll body 1 is 10 ~ 100mm, can guarantee the needs of printing, can alleviate again the weight of roll body 11.
In the present embodiment, the thickness of described copper plate 4 is 10 ~ 14um.For making the utility model reach best result of use, the thickness of described copper plate 4 is 12um.
Copper plate 4 is working faces of laser engraving, so its quality must meet the following requirements: the purity of copper is high, product grain is thin; Coating surface should be smooth without depression, without striped etc.; Coating has enough hardness and toughness.After copper layer plates, also to make through operations such as the combination machine cutting of car mill or the polishings of grinder polisher lapper, make diameter tolerance, parallelism tolerance and the surface smoothness of roller all reach requirement.
In the present embodiment, the thickness of described laser engraving layer 5 is 100 ~ 150um.The degree of depth of laser engraving layer 5 engraving is darker, makes to present stereoeffect after printing.
In the present embodiment, the thickness of described chromium coating 6 is 4 ~ 6um.For making the utility model reach best result of use, the thickness of described chromium coating 6 is 5um.
Because the hardness of copper plate 4 is poor, in when printing easily by scraper scratch, therefore will be at the plated surface last layer hard chromium layers of copper plate 4.Chromium plating need to be passed through following steps: cleaning, degreasing, chromium plating, polishing.Cleaning with the object of degreasing is by the grease of the space of a whole page, dirty removing, and polishing is for the sanding burr at ink cell edge in chrome-plating process is fallen.Gravure printing roller surface institute chromium coating 6 has wearability and the chemical stability of very high hardness and height, by chromium plating, making the copper layer on forme surface injury-free is to make one necessary program of printing plate cylinder, and the pressrun that will improve forme is also mainly to improve the hardness of chromium layer.
In the present embodiment, the two ends of described roll body 1 are fixedly connected with respectively left end shaft 7 and right-hand member axle 8.Roller is divided into shaftless and has axle class, and general small-sized flexible packaging printing machine is all used shaftless hollow roller, and large-sized print machine is with there being axle roller.Above-described embodiment is preferably implementation of the utility model, and in addition, the utility model can also be realized by alternate manner, and under the prerequisite that does not depart from the present utility model design, any apparent replacement is all within protection domain of the present utility model.
