Embodiment Construction
[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0025] see Figure 1-5 As shown, the present invention is an air-cooled UV drying device for an offset printing machine, which includes a substrate 1 and a cooling fan 2. The upper middle of the substrate 1 is provided with a UV-LED point light source 101 along the length direction, and an interface assembly 102 is provided at the side end. The lower end of the base plate 1 is evenly provided with cooling fins 103 along the length direction, the cooling fan 2 is an...

The invention discloses an air-cooling type UV drying device used for an offset press. The air-cooling type UV drying device comprises a base plate and a heat dissipation fan. A UV-LED point light source is arranged in the middle of the upper end of the base plate. An interface assembly is arranged at the side end of the base plate. Heat dissipation fins are arranged at the lower end of the base plate. The heat dissipation fan is an axial flow fan. The length of a shell of the fan is equal to the length of the base plate. A clamping groove is formed in the middle of the air-out side of the heat dissipation fan. Two sets of air outlets are symmetrically formed in the two sides of the clamping groove and used for conducting ventilating and heat dissipation on the UV-LED point light source of the base plate and the heat dissipation fins. One ends of the heat dissipation fins are flush with the edges of the base plate, gaps are formed between the other ends of the heat dissipation fins and the air outlets. According to the UV drying device, a traditional light tube structure is replaced with the UV-LED point light source, heat generating is little, ozone is not generated, and instant lighting-on or lighting-off is achieved; and the heat dissipation fan is the transverse flow fan and fixed to the base plate in a side part clamping-connection mode and can conduct heat dissipation on the two sides of the base plate at the same time, so that the heat dissipation effect is improved.
Description
technical field [0001] The invention relates to the technical field of printing machinery, in particular to an air-cooled UV drying device for an offset printing machine. Background technique [0002] The offset printing machine is a kind of lithographic printing machine. When printing, the printed image and text are first printed from the printing plate to the rubber cylinder, and then transferred to the paper by the rubber cylinder. Offset printing machines can be divided into sheet-fed offset printing machines and web offset printing machines according to different feeding methods; according to the number of printing colors completed in one pass, they can be divided into single-color, two-color, four-color and multi-color printing machines; The largest paper format can be divided into small offset printing machines, six-fold, four-fold, folio and full-sheet printing machines, and there is also a double-sided printing machine that can print on both sides at the same time w...
