Embodiment Construction
[0019] See figure 1 and figure 2 .
[0020] In this embodiment, a water-cooled shutter-type ultraviolet cold light source drying and curing system is installed on the SAY820C9 type electronic shaft-driven paper gravure printing machine.
[0021] Four sets of ultraviolet cold light sources 3, 4, 5 and 8 are placed on the top of the longitudinal beam 1 of the SAY820C9 electronic shaft transmission paper gravure printing machine. The light source 8 is mounted on a fixed bracket 9 .
[0022] Paper guide rollers 7 and 10 are arranged on the front and rear sides of the fixed support 9 , and the paper cooling roller 2 is arranged behind the movable support 6 .
[0023] The distance between the movable support 6 and the fixed support 9 is 1 to 3 meters, that is, figure 2 The variable range of L in , this range refers to the distance between the ultraviolet cold light sources 5 and 8.
[0024] The paper guide rollers 7 and 10 include two upper and lower rollers, and the paper co...
