Description

Technical Field

[0001] The utility model relates to the technical field of ink curing, in particular to a curing device for UV light curing ink. Background Art

[0002] Ultraviolet curing (UV) ink refers to ink that uses ultraviolet light of different wavelengths and energies to form a film and dry the ink under ultraviolet irradiation. Different ultraviolet spectra can generate different energies to polymerize monomers in different ink binders into polymers, so the color film of UV ink has good mechanical and chemical properties. The photoinitiator in UV ink is a compound that is easily excited by light. After absorbing light, it is excited into free radicals and the energy is transferred to photosensitive molecules or photocrosslinkers. However, most of the curing lamps in the current curing devices are exposed, which easily causes dust to enter and adhere to the surface of the curing lamp, which not only affects the subsequent curing effect, but also the falling dust will affect the quality of the finished ink. For this reason, we propose a curing device for UV curing ink. Utility Model Content
