[0002] Label printing machine is a kind of printing label. The label usually adopts curing treatment, that is, the process of converting ink, coating, adhesive, sealant, etc. from liquid state to solid state. The photoinitiator in the agent produces a photochemical reaction to achieve rapid curing. However, the conventional method for printing labels on transparent materials is single-sided irradiation. The curing agent on the printing surface is not easy to be irradiated, and the curing speed is slow, which affects the production speed.

The invention discloses a double-reflection ultraviolet curing device for a label printing machine, which comprises a vertical plate, and a Y-shaped guide port is opened on the vertical plate, and the guide port includes an entrance port and two exit ports. A triangular prism-shaped first reflector is fixedly connected to the inner wall of the entrance, and the first reflector is arranged at an angle of 45° relative to the horizontal direction of the mirror surfaces on both sides of the entrance. The ultraviolet light emitted by the ultraviolet lamp body of the present invention passes through the first reflector to form two beams of light that are vertically opposite to each other, and the two beams of light are irradiated to the second reflector. When the ultraviolet light is emitted, it is reflected by the third mirror and then shoots vertically upwards, that is, the light enters the light outlet and shoots to the convex lens, and the focusing effect is achieved through the convex lens. In addition, the ultraviolet light is hedging after passing through the third mirror, which can The curing agent label set on the transparent material between the two connection frames is irradiated front and back to accelerate its curing speed.
