Technical Field

[0001] The present application relates to the field of printing technology, and in particular to a printing drying UV curing device. Background Art

[0002] In the printing industry, UV curing equipment is also an energy-saving and efficient ink drying equipment. Its main working method is: when the printing machine transfers the ink (UV ink containing specific photosensitive components) to the printed material, because the ink is not dry, the printed product is transported through the UV curing device by the conveyor belt, and the ink absorbs UV light and is completely dried.

[0003] With respect to the above-mentioned related technologies, the inventors believe that in the existing UV curing equipment, the height of the UV lamp is often fixed and difficult to adjust. When encountering printed items of different thicknesses for UV curing, the existing UV lamp is often difficult to adapt to and achieve a suitable drying and curing effect. In addition, the printed items are more prone to deviation and wrinkles during the transportation process, resulting in the UV lamp being unable to UV cure the printed items well. Therefore, a printing drying UV curing device is proposed to solve the above problems.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
