Description

Technical Field

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

[0002] A rotary printing press is a type of printing press, which includes a UV light curing device. After printing on a flexible printing tape, the printed material is conveyed through a conveying structure under a UV light curing lamp so that the UV light irradiates the printed material to cure it. However, the current UV light equipment generates heat during operation, and the heat cannot be ruled out and is likely to affect the irradiation and curing effect.

[0003] For example, a Chinese utility model patent with the announcement number CN218140633U discloses a printing ink curing device, including a cabinet, a conveyor, a curing cover, a protective cover, a UV curing lamp, a heat dissipation fan and a ventilation window; the conveyor is installed on the cabinet, the curing cover is installed on the frame of the conveyor, the UV curing lamp is provided with multiple groups and installed inside the curing cover, and the sides of the curing cover are all installed with ventilation windows. The printing ink curing device conveys the printed articles through the conveyor to enter the fixing cover, and the ink is cured under the ultraviolet light emitted by the UV curing lamp. The UV curing lamp is a cold light source and generates little heat. In addition, under the action of the heat dissipation fan, the air inside the curing cover is circulated to conduct the heat generated by the UV curing lamp without affecting the curing effect of the UV curing lamp.

[0004] In response to the above-mentioned related technologies, this solution installs a cooling fan on the top of the UV curing equipment to discharge the heat generated by the operation of the equipment upwards. However, the function of this solution is relatively simple and can only dissipate the heat of the curing equipment. For printed materials, before they are UV cured, dust and metal debris falling on them can easily affect the UV light curing effect. After UV curing, the temperature of the printed materials rises, and external debris falling on them can easily be adsorbed and adhered, affecting product quality. Therefore, a UV light curing device that can effectively dissipate heat and has strong functionality is needed. Utility Model Content
