Description

Technical Field

[0001] The utility model relates to the technical field of printing machinery and equipment, in particular to UV ultraviolet curing and drying energy-saving equipment for a waterless printing machine. Background Art

[0002] Currently, printing technologies are mainly divided into traditional printing and waterless printing. Traditional printing requires coating a layer of water film on the template, so it will waste a lot of water resources during long-term use. Waterless printing, on the other hand, uses exposure to separate the photosensitive polymer and the silicone layer at the junction, so that the ink is adsorbed on the photosensitive polymer and repelled by the silicone rubber layer.

[0003] After searching, a Chinese patent discloses an LED ultraviolet drying and curing device (authorization announcement number CN212943870U), which includes a workbench and multiple ultraviolet curing lamps. A conveying device is provided in the workbench. A U-shaped positioning plate is fixedly connected to the top of the workbench, and a frame is provided in the U-shaped positioning plate. A movable plate is provided in the frame. Multiple ultraviolet curing lamps are fixedly arranged at the bottom of the movable plate. The side walls of the movable plate are symmetrically fixedly connected with multiple sliders, and the inner wall of the frame is symmetrically provided with multiple slide grooves matching the sliders. Although this patented technology can facilitate the adjustment of the height of multiple ultraviolet curing lamps, and thus facilitate the use of workpieces of different heights, ensuring its curing effect, it can also protect the workpiece during the curing process to prevent external factors from interfering with it, and can automatically close the ultraviolet curing lamp after curing is completed to prevent its radiation from affecting people.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that the above equipment achieves the curing effect of the workpiece by setting an ultraviolet curing lamp, but the light of the ultraviolet curing lamp is relatively scattered, resulting in a large part of the curing light being irradiated in the drying box, thereby reducing the curing effect of the curing lamp and wasting some light resources. In addition, the material to be cured needs to be cured on both sides, and manual turning is inefficient, which reduces the production efficiency of the material. Utility Model Content

When the material to be cured enters the curing drying box 3, the UV curing lamp 16 on its inner wall will emit strong ultraviolet rays, which will irradiate the surface of the material after pre-coating ink, and trigger a chemical reaction to quickly harden and form a solid image. At this time, part of the ultraviolet rays will be refracted by the diffuse reflection plate 8 onto the material to be cured, thereby reducing the problem of light resource waste caused by ultraviolet dispersion;

[0041] When the servo motor 2 7 is started, the threaded rod 15 can be driven to rotate, which can drive the threaded block 14 to slide in the mounting groove 13, thereby driving the connecting rod 9 to rotate, and the connecting rod 9 can also rotate the animation reflector 8, so that the angle of the diffuse reflector 8 can be adjusted to adapt to different ultraviolet irradiation angles and improve adaptability;

[0042] When the material passes through the turning frame 17 after being solidified, the controller 6 can control the servo motor 3 12 to start. At this time, a clamping gap is formed between the two tripods, which will limit the two sides of the material. Along with the rotation of the rotating roller 18, the two turning frames 17 are driven to rotate, thereby achieving the purpose of automatically turning the material over to improve production efficiency.
