Description
Technical field
The utility model relates to printing machine, particularly a kind of LED light source device of printing machine.
Background technology
LED light source device is for being arranged on web press, dry device is carried out to the ink be printed in web surfaces, it mainly comprises framework (or claiming casing), framework has can the passage that passes of supply spool paper, the lower portion position be positioned at above roll web is provided with at least two group light source modules side by side, two groups of light source module intervals are arranged, gap between adjacent light source module forms gas channel, framework is positioned at the blower fan being provided with above light source module and can blowing downwards, during work, on the ink of the light-wave irradiation roll web thereunder that light source module produces, make the ink on roll web dry rapidly, the wind of blower fan blowout then matches with the copper pedestal being connected light source module and is combined into light source module and dispels the heat, web surfaces is caused to be out of shape to prevent light source die group overheated, affect printing effect.
But still there is following deficiency in existing LED light source device: 1, the caloric value of LED light source module is larger, and the air permeability of lower portion is poor, coordinate the dry effect of carrying out dispelling the heat of fan poor by copper pedestal, work long hours down, easily cause lower portion temperature too high, make the areal deformation of the roll web carrying out ink setting in framework, affect printing effect.2, light source module interval is arranged, and when the unified drying of print request integral planar, spaced light source module there will be the situation that below gap, light is uneven, causes dried roll web to occur intermittent colour band, reduces printing effect.
Summary of the invention
The purpose of this utility model is the LED light source device providing the better printing machine of a kind of heat dispersion, and it can prevent the Yin Wendu of the roll web carrying out ink setting too high and cause areal deformation.
The LED light source device of printing machine described in the utility model, comprise casing, what casing had that paper supply passes wears paper passage, box house is positioned at the position of wearing above paper passage and is fixed with pedestal, slotted eye place in the middle part of pedestal is provided with multiple LED light source module be arranged side by side, described pedestal is provided with the cold water contacted with LED light source module to arrange, the entrance of cold water row leads to outside cold water inlet pipe, and outlet is then led to the warm water recovery tube of outside.
The LED light source device of printing machine described in the utility model, pedestal is provided with the cold water contacted with LED light source module arrange, during work, cold water continues to flow into cold water row through cold water inlet pipe, LED light source module is transmitted to the heat constant absorption on cold water row surface, the temperature of LED light source module and cold water row is made to cross quick reduction, and cold water absorbs the heat of LED light source module conduction and flows to warm water recovery tube reclaim through the outlet of cold water row after heating up, circulation like this, the heat dispersion of the LED light source device of printing machine can be increased substantially, ensure that the temperature in casing maintains lower level, thus the roll web Yin Wendu preventing from carrying out ink setting is too high and cause areal deformation.

Detailed description of the invention
As shown in Figures 1 to 6, the LED light source device of described printing machine, comprise casing 1, what casing 1 had that paper supply passes wears paper passage 11, casing 1 inside is positioned at the position of wearing above paper passage 11 and is fixed with pedestal 2, slotted eye place in the middle part of pedestal is provided with multiple LED light source module 3 be arranged side by side, LED light source module 3 is electrically connected with dc source or alternating current by power line (not shown), on the surface of the light-wave irradiation that LED light source module 3 sends roll web (not shown) thereunder, described pedestal 2 is provided with the cold water contacted with LED light source module and arranges 4, cold water arranges 4 inner hollow, its entrance 41 leads to outside cold water inlet pipe (not shown), export 42 to lead to outside warm water recovery tube (not shown).During work, cold water continues to flow into cold water row 4 through cold water inlet pipe, LED light source module 3 is transmitted to the heat constant absorption that cold water arranges 4 surfaces, the temperature of LED light source module 3 and cold water row 4 is made to cross quick reduction, and cold water absorbs heat that LED light source module 3 conducts and flows to warm water recovery tube reclaim through the outlet 42 of cold water row 4 after heating up, circulation like this, the heat dispersion of the LED light source device of printing machine can be increased substantially, ensure that the temperature in casing 1 maintains lower level, thus prevent the Yin Wendu of the roll web carrying out ink setting too high and cause areal deformation.
Closely arrange between adjacent LED light source module 3, there is not gap, LED lamp bead in all LED light source module 3 is evenly arranged, when can ensure that LED light source module works, the surface of the roll web below it is illuminated uniformly, there will not be the situation that light is uneven, avoid dried roll web to occur intermittent colour band, thus improve printing effect.
Casing 1 has at least two relative sidewalls to have air vent 12,13, one of them sidewall is provided with at least one blower fan 5(such as figure in the region of air vent be the situation of three blower fans), the air that can accelerate casing 1 inner and outside by blower fan 5 flows, and lowers the temperature further to casing 1 inside.
Described pedestal 2 has the through hole 21 leading to pedestal 2 upper and lower space, the roof of casing 1 is provided with the situation that at least one fan 6(that can blow to the direction of through hole 21 as shown is three fans), the region of the corresponding fan 6 of casing 1 roof has air holes 14, the wind via through holes 21 that fan 6 blows out enters the space below pedestal 2 and the direction of advancing perpendicular to roll web, form air curtain, the surface of roll web is lowered the temperature, prevents roll web Yin Wendu too high further and cause areal deformation.
For improving the light wave utilization rate of LED light source module 3, position mounting block tabula rasa 15 above paper passage 11 can being crossed in casing 1 outer wall correspondence, keeping off back from crossing the light wave that paper passage 11 sheds on the surface of the roll web in this region.
For raising LED light source module 3 and cold water arrange the heat transfer efficiency between 4, can arrange heat conduction glue-line (not shown) between LED light source module 3 and cold water arrange 4, cold water row 4 is contacted with LED light source module 3 by heat conduction glue-line.
