Problems solved by technology

[0002] At present, the drying system of the rotogravure printing machine used in the printing industry all adopts the hot air drying system. The principle of purely relying on the principle of temperature drying makes some special processes impossible to complete. For example, the rotogravure printing machine cannot print leather oil, freezing snow, etc., so it is extremely Earth limits the equipment's ability to adapt to production

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...

Abstract

The invention provides an UV drying curing system added on a rotogravure printing machine. The system comprises a rotogravure printing machine. The technical scheme is that the top of a longitudinal beam of the rotogravure printing machine is provided with a water-cooling shutter type ultraviolet cold light source drying curing system. The water-cooling shutter type ultraviolet cold light source drying curing system is formed by four sets of ultraviolet cold light sources, wherein three sets are parallel together and are installed on a mobile support, and the other independent set is installed on a fixed support. The front edge and the rear edge of the fixed support are provided with dancing rolls. A paper cooling roller is arranged on the rear of the mobile support. The system enhances production adaptive capacity of an original rotogravure printing machine, realizes a connecting line gravure multiple combination process, overcomes restrictions that a rotogravure printing machine cannot print cortex oil, ice points and snowflake, widens production range of the device, and satisfies more diverse technological requirements.

Description

technical field [0001] The invention relates to printing equipment, in particular to a UV drying and curing system installed on a rotary gravure printing machine. Background technique [0002] At present, the drying system of the rotogravure printing machine used in the printing industry all adopts the hot air drying system. The principle of purely relying on the principle of temperature drying makes some special processes impossible to complete. For example, the rotogravure printing machine cannot print leather oil, freezing snow, etc., so it is extremely The earth limits the production adaptability of the equipment. Contents of the invention [0003] In order to overcome the limitation that the rotogravure printing machine cannot print leather oil, freezing point snowflakes and other process requirements, through the research on the drying and curing system of some special process requirements, this invention provides a UV drying and curing system installed on the rotogr...
