The utility model discloses an LED UV curing system for intermittent rotary printing press, which comprises a shell and a LED lamp substrate with a cooling device arranged in the shell. The cooling device is located above the LED lamp substrate, a longitudinal opening is arranged in the middle of the bottom wall of the shell, and the LED lamp substrate is arranged on the longitudinal opening. A partition board is arranged from the top of the cooling device of the LED lamp substrate to the top wall of the shell, and a groove is arranged at the top of the cooling device. The inner cavity of the shell is divided into left and right parts by the partition board, and the suction chamber and the jet chamber are on the left and the jet chamber are on the right sides of the shell of the LED lamp substrate. A number of typhoon fans are arranged on the baffle board, and the advantages are that the baffle board and the cooling device can be movably connected to facilitate the installation and maintenance of the fan and the cooling device. Three fans are arranged on the partition board, which speeds up the air flow between the suction chamber and the jet chamber and improves the drying and curing efficiency of printing substrate ink.

技术介绍
随LED灯粒的技术发展,越来越多的LED灯粒固化装置应用于印刷机油墨固化领域。通过充分利用LED面光源能耗低、波长稳定、安全性高、寿命长等优势,得到高密度有用波段紫外光固化能量,达到固化UV油墨的目的,从而替代传统卤素灯,且能耗仅为卤素灯的25%左右。目前使用的印刷油墨固化装置,包括遮光罩及设置于其上方的LED灯光源。LED灯粒的功率可达每粒3W,其中有50%左右的能量在PN结处发热,而PN结的温度要求不能超过125度;PN结与金属基板直接连接,基板温度要求不超过80度,普通风冷、水冷方式接近或超出80度,对灯粒寿命影响较大;一般冷却方式,较难顺利把基板的热量带走,温度积聚过高,光衰快,灯粒寿命大大缩短。专利文献CN105398205A,公开了一种LEDUV印刷固化装置,包括一带有冷却装置的LED灯粒基板,所述冷却装置位于所述LED灯粒基板上方,还包括一壳体,所述壳体的底壁中部具有一纵向开口,所述LED灯粒基板设置于所述纵向开口上;在所述LED灯粒基板的冷却装置的顶端至所述壳体的顶壁设置一隔板,所述隔板将所述壳体内腔分割为左右两部,左部为吸气室、右部为喷气室;所述LED灯粒基板两侧的所述壳体的底壁上,分别设置有吸气孔、喷气孔,所述吸气孔、喷气孔分别与所述吸气室、喷气室连通;在所述壳体的后部、位于所述吸气室、喷气室之间设置一风扇,所述风扇的进风口朝向所述吸气室、出风口朝向所述喷气室;所述吸气室通过所述风扇的作用力从所述吸气孔 ...
