The beneficial effect that the present invention has is:
1), in steel tube surface reference numbers and bar code information, give unique identify label of steel pipe.
2) to possess adhesive force good for the UV bar code, nonabradable characteristics, and what can be advantageously applied to steel pipe is online by following the tracks of.
3) adopt the UV curing technology, can moment make the bar code drying, do not affect rhythm of production, can the original production technology of slitless connection.
4) utilizing the present invention can make steel pipe being greatly improved aspect a sign of following the tracks of, is the basic link of realizing that the steel pipe's production process identifier is reviewed.
5) the invention is not restricted to be used in pipe production line, can apply at steel plate or the more severe production line of other conditions.

The specific embodiment
Below in conjunction with drawings and Examples, the present invention is described further.
As shown in Figure 1, the present invention includes and comprise UV barcode jet printing parts 1, digital spraying print parts 3 and UV hardening element 2; Digital spraying print parts 3, UV barcode jet printing parts 1, and UV hardening element 2 is arranged on successively from right to left by the direction of advance of coding steel pipe respectively.What barcode jet printing adopted is UV paint, and adopts UV hardening element 2 instantaneous solidification; The content of sign is that numeral adds bar code, is applied to the online by a tracking of steel pipe.
As shown in Figure 5, digital spraying print parts 3, comprise digital shower nozzle 20, controller 21 and pump cabinet 22; Numeral shower nozzle 20You tri-tunnels, the first via is electrically connected to controller 21, and other two tunnels connect pump cabinet 22, and digital spraying print parts 3 can be from choosing on the market.Pump cabinet 22 supplies with coating, the content of controller 21 control figure shower nozzle 20 spray printings to digital shower nozzle 20.
As shown in Figure 2, Figure 3, Figure 4, UV barcode jet printing system 1 comprises bar code shower nozzle 4, fuel feeding membrane pump 5, three filters 6, two tee ball valves 7, paint kettle 8, electrical ball valves 9 and reclaims membrane pump 10; Bar code shower nozzle 4 has three tunnels, and the first via is connected to form for oil circuit with first port of paint kettle 8 through fuel feeding membrane pump 5, first filter 6, first tee ball valve 7; The second second, tunnel tee ball valve 7, second filter 6, electrical ball valve 9 are connected to form oil return line with second port of paint kettle 8; Third Road is connected to form the recovery oil circuit through the 3rd filter 6, recovery membrane pump 10 with the 3rd port of paint kettle 8; Bar code shower nozzle 4 is arranged on the top that requires spray printing bar code steel pipe 11.When steel pipe 11 arrives precalculated position, bar code shower nozzle 4 starts the spray printing bar code, and now electrical ball valve 9 is closed, to maintain paint pressure in pipeline.During spray printing, for oil circuit, bar code shower nozzle 4, oil return line, paint kettle 8, do not form loops, the UV paint is constantly flowed, avoid paint to solidify clogged oil line.Oil return line reclaims the oil-feed paint can by the unnecessary paint of bar code shower nozzle 4 ejections, is recycled.Bar code shower nozzle 4 comprises valve plate 12, spray gun 13 and protective cover 14; spray gun 13 is fixed on valve plate 12; the asphalt channel of promising spray gun 13 fuel feeding in valve plate 12; the protective cover 14 of protection spray gun 13 is fixed on valve plate 12; accumulator tank 15 is arranged at protective cover 14 bottoms, for collecting the unnecessary paint of spray gun 13 ejection.Paint kettle 8, comprise ladle body 16, mixer 17, air filter 18 and heater 19; Mixer 17 is arranged on ladle body 16 tops, and heater 19 is arranged on ladle body 16 bottoms, and ladle body 16 sides are equipped with air filter 18.19 pairs of UV paints of heater are heated, and to reduce the viscosity of paint, strengthen the spray printing effect.17 pairs of UV paints of mixer are stirred, and make UV paint temperature even, and in flow regime.The passage that air filter 18 provides the UV paint to be connected with external environment condition, and the impurity in the elimination environment, avoid polluting the UV paint.In bar code shower nozzle 4, be equipped with many spray gun 13, can one time the spray printing bar code that goes out to need.
As shown in Figure 6, UV cure system 2, comprise curing room 26, uviol lamp 25, airduct 24 and cooling blower 23; Uviol lamp 25 is arranged in curing room 26, cooling blower 23 is arranged on curing room 26 end faces, cooling blower 23 is by airduct 24 access curing rooms 26, airduct 24 oral areas are arranged on uviol lamp 25 tops, uviol lamp 25 is placed in above the steel pipe 11 that has sprayed bar code, and the steel pipe 11 that has sprayed bar code can pass in curing room 26.Sprayed the steel pipe 11 of bar code through out-of-date, uviol lamp 25 sends ultraviolet ray bar code is solidified.Cooling blower 23 is taken near hot-airs uviol lamp 25 away by airduct 24, and protection uviol lamp 25 is unlikely overheated and damage.
The step of coding is as follows:
At first steel pipe 11 axial advancement are to the spray printing position, 1 meeting of UV barcode jet printing system is the surface to steel pipe 11 by the bar code information spray printing, then steel pipe 11 moves on vertically, digital spraying print system 3 is the rear end in bar code by the digital information spray printing subsequently, UV cure system 2 will enter the bar code instantaneous solidification of curing room 26, thereby form one group of spray printing information, as shown in Figure 7.
With reference to accompanying drawing, provide above-described embodiment.To contribute to understand the present invention by embodiment, but not limit content of the present invention.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention, all should think protection scope of the present invention.
