Abstract
The invention discloses rolling type deoxygenation equipment for electron beam printing of webs and a deoxygenation method. The deoxygenation equipment is connected with electron beam curing equipment which is used for curing ink on the webs through electron beams. The deoxygenation equipment comprises a roller and a transmission shaft, wherein the roller is arranged on the transmission shaft andis positioned above an electron beam curing position. Thus, a nitrogen protection bin which is used at present can be eliminated and the requirement of controlling the content of active gas during electron beam curing can be met only by arranging the deoxygenation equipment on the electron beam curing equipment of an ordinary web press, so that the cost of the whole printing equipment is greatly reduced; and the deoxygenation equipment has high market competitiveness.
Description
Technical field
The present invention relates to roll web electron beam printing technical field, particularly a kind of roll web electron beam printing rolling-type deaeration plant and deoxidation method.
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 also develops towards quick-drying, nontoxic and environmental protection direction, and more representational is exactly water-based inks, UV curable ink and electron beam radiation cured printing ink.Using more energy-curable technology at present 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 the clean no dirty point of printed matter surface, little, the trace good brightness of dot gain rate.
Though electron beam curing ink has a lot of benefits, still there is certain shortcoming, its curing apparatus cost height is obstacle maximum in applying.At present, though EB only needs an ion cathode tube when solidifying, must strictly control the active gases content (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; require nitrogen gas concn to be not less than 99.5%, make that the printing ink on the stock 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.
Summary of the invention

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:
Roll web electron beam printing rolling-type deaeration plant provided by the invention and deoxidation method; 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
The schematic diagram in nitrogen protection storehouse when Fig. 1 is the electronic beam curing of printing equipment in the prior art.
Fig. 2 is the schematic diagram of the embodiment of roll web electron beam printing rolling-type deaeration plant of the present invention.
Fig. 3 is the flow chart of roll web electron beam printing rolling-type deoxidation method of the present invention.
The specific embodiment
For making purpose of the present invention, technical scheme and effect clearer, clear and definite, below with reference to accompanying drawing and give an actual example that the present invention is described in more detail.
See also Fig. 2, its Fig. 2 is the schematic diagram of the embodiment of roll web electron beam printing rolling-type deaeration plant of the present invention.In the present embodiment, described deaeration plant is a rolling device, is used for fully contacting with printing ink on the roll web by rolling device, and printing ink and air on the roll web are completely cut off.The way that this mode by roll extrusion is isolated with the printing ink on the roll web and air, its isolated effect is better, has fully satisfied the requirement of electronic beam curing.As shown in Figure 2, described rolling device comprises roller 600 and power transmission shaft 700, and described roller 600 is arranged on the power transmission shaft 700, and is positioned at the top of electronic beam curing position; Printing ink on roll web is positioned at the electronic beam curing position, and described power transmission shaft 600 drives rollers 700 and rotates, and roller 700 is fully contacted with printing ink on the roll web, comes thereby itself and air completely cut off.Be, described rolling device is mounted in the electron beam curing apparatus place of printing machine with being to be understood that, only is the local enlarged diagram for the ease of understanding among Fig. 2.
The nitrogen protection storehouse is mainly provided by AGA gas companies and the such gas supplier of Praxair company now, also needs to set up cooler therein, and it is used for the temperature of managing electronic beam-curable equipment itself." reason of the radiator in its usage and the automobile is the same." when in many package processing factory the cooling system that printing machine uses having been arranged, electron beam curing apparatus is installed may be also needed oil (gas) filling device again, thereby cause cost too high, the EB technology can't be promoted fast.
Further, can also be provided with on the surface of described roller for the roller brush that the printing ink on the roll web and air is isolated.
