Description

A replace lighting fixture fast for transformation of UV offset press

Technical Field

The utility model belongs to the technical field of auxiliary mechanical equipment, and particularly relates to a quick replacement lamp holder for UV offset press transformation.

Background

Offset printing presses (offset printing presses) are a type of lithographic printing press in which printing is performed by first printing a print from a printing plate onto a blanket cylinder and then transferring the print from the blanket cylinder to a sheet of paper. The printing ink used in offset printing is of various types, and because the printing speed of offset printing machines is faster and faster, the requirements of printing operators and presswork users on the environmental protection performance of products are higher and higher, the requirements of the printing ink on good transfer performance, high tinting strength, high drying speed after printing, long on-machine non-skinning time, low heavy metal content in printing ink products and the like are also higher and higher. The UV offset printing ink is a high-viscosity pulpy fluid, and after the UV offset printing ink is cured by means of a photoinitiator to absorb radiation of ultraviolet light, a monomer and a prepolymer are initiated to carry out polymerization and crosslinking reaction to generate curing, and most of the UV offset printing ink utilizes light with the wavelength of below 400nm as radiation energy to initiate liquid printing ink with chemical reaction activity to be quickly converted into solid printing ink.

The existing UV lamp is a gas discharge lamp, and its working principle is: quantitative high-purity mercury (mercury) is added into a vacuum quartz tube, and ion discharge is generated by providing voltage difference (voltage drop) for electrodes at two ends, so that ultraviolet radiation is generated, the power is generally 18-21 KW, the energy consumption is high, wherein white light is also called visible light accounting for about 40%, infrared light accounting for about 30%, the temperature is high, ultraviolet rays which can be really and effectively used for curing UV ink only account for about 20%, namely nearly 80% of energy is basically wasted. In addition, under the irradiation of the UV lamp, oxygen molecules in the air can be activated, so that ozone is generated, and ventilation equipment such as an exhaust pipe is also needed. The ultraviolet lamp tube can be aged after being used for a certain time, the energy is weakened, and the service life of the ultraviolet lamp tube is about 1000 hours generally. Because of short service life, the traditional UV mercury lamp has the defects that the radiation energy of the UV mercury lamp can be gradually attenuated along with the increase of the service time, the UV lamp tube needs to be replaced regularly, the inconvenience is brought to daily maintenance, and the service scene is limited.

According to the comprehensive working scheme of energy conservation and emission reduction of thirteen five, the method deeply implements 'Chinese manufacturing 2025', deepens the fusion development of manufacturing industry and the Internet, and promotes the high-end, intelligent, green and service of manufacturing industry. And a green manufacturing system is constructed, the green management of the whole life cycle of the product is promoted, and the structure of the industrial product is continuously optimized. Support the transformation and the upgrade of the important industry, encourage enterprises to aim at international benchmarks in the same industry, comprehensively improve the levels of product technology, process equipment, energy efficiency, environmental protection and the like, and promote the transformation and the upgrade of the traditional industry.

A light Emitting diode (led), which is a solid semiconductor device capable of converting electrical energy into visible light, can directly convert electricity into light. The LED chip comprises a core semiconductor chip, one end of the chip is attached to a support, the other end of the chip is a negative electrode, the other end of the chip is connected with a positive electrode of a power supply, and the whole chip is packaged by epoxy resin. The LED uses a cold light source, has small glare and does not generate harmful substances in use. The LED has low working voltage, adopts a direct current driving mode, has the electro-optic conversion efficiency of more than 50 percent, and saves energy by 40 to 60 percent compared with the traditional mercury lamp light source under the same illumination effect. The LED has better environmental protection benefit, the waste can be recycled, no pollution is caused, and mercury element is not contained, so that the LED belongs to a typical green lighting source. The UV curing system on the printing line of the existing offset press is replaced by the LED light source, so that the energy consumption can be saved, and the printing line is safer and more reliable.
