Description
Technical field
The utility model belongs to ultraviolet ink and curing technology field, and particularly a kind of jet ink solidifies with LED mixed wavelengths lamp source.
Background technology
Ultraviolet ray (UV) ink and the curing technology that are used for numerial code spray drawing have had significant progress in recent years, its application is expanded to multiplex's industry application gradually from concentrating at first advertising sector, such as glass decoration, and metal finishing, the fields such as household household electrical appliances.The UV ink solidifies under the irradiation of ultraviolet source in the air brushing process immediately, does not have VOC, and again convenient use of environmental protection.
Common UV ink cured light source generally has broad spectrum, longwave optical is solidified mainly for the ink deep layer, the quality that deep layer is solidified directly have influence on the UV China ink curing and and stock between and adhesive force, the ink of poor adhesive force easily splits away off from stock, has a strong impact on spray printing quality and durability.Short wavelength light is solidified mainly for ink surface, and surface cure not exclusively not only affects the air brushing effect, and the ink that not exclusively solidifies can be clamminess, and stacks when printing rewinding with coiled strip because ink is not exclusively dried at stock, and picture is easily destroyed.
Industrial digit inkjet printer adopts metal halogen UV fluorescent tube (such as the H type, the D type) UV curing ink. the metal halogen spectral width, and the utilization rate that UV solidifies is not high, and a large amount of transform light energy become used heat.Because the efficiency of light energy utilization is not high, need to solve problem of solidification with powerful lamp source on the one hand, general UV lamp source energy answers the air brushing wide cut different with speed and different at 2800-3600W or higher.A large amount of used heat have produced the apparatus overheat problem on the other hand.The operating temperature General Requirements of UV type ink and shower nozzle is about 40 degree, and the heat energy that the UV light source produces makes the equipment part reach degree more than 50, and to integrated circuit board, the protection of shower nozzle and ink and equipment continuous operation stability all can have a negative impact.Numerial code spray drawing manufacturer usually can install many heat abstractors at machine and solve problems of excessive heat.The operating ambient temperature of UV spray drawing machine requires about 25 degree, and the generation of a large amount of used heat has strengthened the refrigeration expense of working environment.
Metal halogen UV fluorescent tube needs the regular hour to reach specified power after lighting, so in whole air brushing process, comprise that the air brushing headstock is in air brushing district and non-air brushing district, UV lamp source keeps long and opens. solidify the ink in the spray nozzle in non-air brushing district in order to prevent UV light, cause shower nozzle to stop up even scrap, equipment manufacturers often add shutter in UV lamp source, when light source is in non-air brushing district, shutter close is revealed to prevent UV light. be not easy to realize but will realize that light is not revealed fully, the complexity that such structure has also increased design and safeguarded, and the energy consumption of UV lamp source in non-air brushing zone all changed into used heat.High-power UV light source is dealt with improperly and also can be baked wrinkle even burned stock except producing used heat, brings impact for the air brushing quality, and stock wrinkling when more serious can be clipped expensive shower nozzle, causes very large economic loss.
High-power UV light source is dazzling in addition, and light diffusion is to problems such as operating personnel's skins.For fear of these problems, equipment manufacturers' employing equipment adds the method for outer cover, and the headstock of UV lamp source and mounting spray head is closed. not only strengthened manufacturing cost but do like this, equipment cooling has also been had higher requirement.
The stability in UV lamp source directly affects solidification effect. and the life-span of metal halogen UV fluorescent tube (H type or D type) is only about 1000 hours.The service life of UV fluorescent tube is short to bring expensive maintenance and inventory problem to terminal client.
In order to solve above series of problems, useful LED-UV light source solidifies special LED-UV ink .LED-UV wavelength and generally adopts 365nm or 395nm on the market, and the lamp pearl of single wavelength is integrated, reaches the curing that the 200-600W luminous power realizes ink.Compare common UV lamp source power consumption 2800-3600W, LED-UV technical energy saving successful.
LED-UV belongs to cold light source, and the soft blueness that the LED-UV light source sends does not stimulate human eye, join with low-power, the stock of mentioning before can solving is to a great extent examined bad, used heat, and the problem such as light diffusion.Led light source can instant igniting; thereby on device design, can accomplish immediately to light when the lamp source enters the air brushing district at every turn; extinguish when leaving the air brushing district. so not only energy-conservation; more can protect the shower nozzle .LED-UV lamp pearl life-span long; generally 15; 000-25,000 hour is more than ten times of common UV lamp tube service life.
The major obstacle of LED curing technology is that the special common UV ink of the high .LED-UV ink of LED-UV ink price cost ratio is expensive more than 50%, bring very large difficulty for device end user's cost control. moreover, ink replacement is not a nothing the matter concerning the client, need to do a large amount of checking in early stage and preparation, by the key indexs such as color and adhesive force on the different stock of lot of experiment validation, proof procedure is long. and this also is that present this technology is in the slower reason of industrial numerial code spray drawing equipment promotion progress.
