Description
Technical field
The utility model relates to printing machine, particularly a kind of web press.
Background technology
Web press mainly comprises body, body is provided with paper base, look seat, gloss oil seat along the direction that roll web runs, and collection Zuo Deng mechanism, wherein, roll web completes ink printing by impression cylinder and plate cylinder on look seat, the quantity of look seat generally has multiple, and the color of not homochromy seat is generally different; The effect of gloss oil seat be to printing after the surface of roll web do glazing process, body is provided with the light supply apparatus ink on the surface of the roll web after completing ink printing and glazing process and gloss oil being carried out to dry solidification being positioned at each look seat and the gloss oil seat downstream position along roll web traffic direction, obviously, the dry solidification effect of light supply apparatus directly affects final printing quality.
What traditional web press was conventional is organic solvent type ink or gloss oil, and it carries out dry solidification by infrared or hot blast, and dry solidification speed is slow, weak effect, and not environmentally.
For this reason, prior art adopts UV ink and gloss oil as printing and glazing raw material, and by UV light source, drying is carried out to it, make UV ink and gloss oil instantaneous solidification, but adopt the drying of UV technology to still have following deficiency: 1, during UV solidification, the temperature of the UV fluorescent tube of UV light supply apparatus self is higher, and the infrared waves of UV spectrum are more, larger heat can be produced, in standby, UV fluorescent tube is open, the heat that the heat of the generation of himself and the infrared waves of UC spectrum produce jointly easily causes roll web to burn, and causes fire.2, flexible package class roll web falls because using the rear high temperature difficulty of UV solidification, and film, paper surface are out of shape, and affect printing effect.
Summary of the invention
The purpose of this utility model is the web press providing a kind of printing effect better and safer.
Web press described in the utility model, comprise body, the direction that body runs along roll web is provided with paper base, look seat, gloss oil seat, and collection seat, body is provided with light supply apparatus being positioned at look seat and the gloss oil seat downstream position along roll web traffic direction, the paper roll of roll web is loaded on paper base, free end is successively through look seat, gloss oil seat, and be placed on the reel of collection seat by volume after the light supply apparatus of correspondence, described light supply apparatus comprises 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 mould to arrange, the entrance of cold water row leads to outside cold water inlet pipe, outlet is then led to the warm water recovery tube of outside, the wavelength of the sensitising agent of the gloss oil on the ink on look seat and gloss oil seat is the mixing wave band of 365 ~ 395UM, the Spectral matching exported with LED light source module.
Web press described in the utility model, sensitising agent wavelength is adopted to be the ink of the mixing wave band of 365 ~ 395UM and gloss oil as the raw material of printing and glazing, the Spectral matching that itself and LED light source device export, time on the ink of spectral illumination in web surfaces that LED light source module produces or gloss oil, due in its spectra collection, the several times of the spectrum that the luminous intensity of unit are produces for UV fluorescent tube, effective removal infrared band, reduce heat, ensure that web surfaces temperature is in lower temperature, in addition, arrange owing to pedestal being provided with the cold water contacted with LED light source module, 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, reduce further the temperature of web surfaces, thus can while preventing fire, gloss oil and the solidification of ink wink-dry can also be made more easily.
