Description
Technical field
The utility model relates to roll web electron beam printing technical field, particularly a kind of roll web electron beam printing rolling-type deaeration plant.
Background technology
Along with improving constantly of material life, the consumer not only has been confined to visual enjoyment to printed matter, and the requirement of product environmental protection aspect is also being improved constantly, and this has proposed the new ideas of environmental protection just for China's printing industry.In press, printing ink is also towards quick-drying, nontoxic and environmental protection future development, and more representational is exactly water-based inks, UV curable ink and electron beam radiation cured printing ink.Using at present more energy-curable technology mainly is that UV photocuring and acceleration high-power electron beam (EB) solidify two kinds.
Wherein, electron beam radiation cured printing ink refers to adopt the printing ink of beam energy curing.Be exactly printing ink under the radiant energy irradiation, set or be hardened on the stock, thus obtain dry trace.The advantage of electron beam curing ink is a lot:
(1) solid content after it solidifies is 100%, does not contain organic volatile matter (VOC), belongs to zero-discharge technology;
(2) because the radiation of main dependence high voltage low current electron beam realizes the drying of printing ink etc., save energy, saved production cost;
(3) hardening time of electron beam curing ink very short, general only needed 0.1 second can anchor at substrate surface by finish-drying, thereby increased substantially operating efficiency;
(4) the printing ink marks of electron beam curing ink printing has very strong resistance, form the high molecular weight steric network polymers because of the chemical substance in the printing ink by cross-linking reaction simultaneously, so ink pellet surface has very strong chemical-resistance and crocking resistance, can also guarantee that printed matter surface is clean without dirty point, little, the trace good brightness of dot gain rate.
Although electron beam curing ink has a lot of benefits, still there is certain shortcoming, its curing apparatus cost height is the obstacle of applying middle maximum.At present, although only need an ion cathode tube when EB solidifies, must strictly control the active gases content (such as oxygen) that solidifies in the process chamber.Present way is when electron beam curing apparatus 20 is cured; increase a nitrogen protection storehouse 10, as shown in Figure 1, by 10 li inflated with nitrogen in the nitrogen protection storehouse; the printing ink on the stock require nitrogen gas concn to be not less than 99.5%, so that can make itself and oxygen completely cut off when EB solidifies.So, the EB curing apparatus is very complicated, and cost is very high, is unfavorable for the large-scale promotion of EB curing technology.In addition, when web printing, can't utilize EB to be cured, also be the problem that can't overcome in the present EB curing technology.
In view of this, prior art is still waiting to improve and improve.

A kind of deoxidation method of described roll web electron beam printing rolling-type deaeration plant, wherein, described deoxidation method may further comprise the steps:
Before S100, printing machine are sent to the electronic beam curing station with the printing ink on the roll web;
S220, power transmission shaft drive roller and rotate, and roller is fully contacted with printing ink on the roll web, thereby itself and air are completely cut off;
S221, roll web are cured in the electronic beam curing position;
After S222, curing finished, roller and described roll web were separated.
The deoxidation method of described roll web electron beam printing rolling-type deaeration plant, wherein, before described step S100, described paper buffer gear slows down to roll web.
Beneficial effect:
The roll web electron beam printing rolling-type deaeration plant that the utility model provides; only need to set up described deaeration plant at the electron beam curing apparatus of common web press; just can remove present employed nitrogen protection storehouse; the demand of control active gases content when finishing electronic beam curing; greatly reduce the cost of whole printing equipment, have the very strong market competitiveness.
Description of drawings
