Background Art

[0002] Existing viscose often contains a large amount of organic solvents as coating agents, and these organic solvents will escape in the form of volatile organic compounds (VOCs). Since these volatile organic compounds are toxic, they will cause great harm to the human body and the environment.

[0003] UV-curable resins are becoming more and more widely used because they do not contain volatile organic compounds (VOCs) and have a fast reaction speed. UV-curable resins will not dry out or change viscosity like volatile (solvent or water-based) inks or coatings.

[0004] However, existing UV light sources used to cure adhesives often evenly distribute UV light emitting diodes on a flat lamp tube, so the angle range that the existing UV light sources can irradiate is not large.

[0025] See also Figure 1 In an embodiment of the present invention, the improved structure and method of the coating device of the present invention are illustrated by the above-mentioned drawings, which includes a combined device of a feeding module 1, a UV light adhesive curing light box 2, a UV glue coating module 3 and a receiving module 4.

[0026] In this embodiment, an input port 21 and an output port 22 are respectively provided at both ends of the UV light adhesive curing light box 2, a UV light curing channel 20 connected to the input port 21 and the output port 22 is provided inside the UV light adhesive curing light box 2, and a plurality of transmission rollers 23 are sequentially arranged in the UV light curing channel 20 between the input port 21 and the output port 22, and an air supply module 24 connected to the UV light curing channel 20 is provided at the top of the UV light adhesive curing light box 2; a plurality of V-shaped UV light irradiators 25 are arranged in the UV light curing channel 20 Each V-shaped ultraviolet irradiator 25 is arranged in sequence along the axial direction between the input port 21 and the output port 22, and each V-shaped ultraviolet irradiator 25 includes a plurality of ultraviolet light emitting units 251 and is arranged into two ultraviolet lamp rows 252 along the extension direction of each V-shaped ultraviolet irradiator 25. There is a predetermined angle 253 between each ultraviolet lamp row 252. The air supply module 24 can drive air to input and output the ultraviolet curing channel 20, so that each V-shaped ultraviolet irradiator 25 in the ultraviolet curing channel 20 can dissipate heat.

[0027] Figure 1 and Figure 2 It can be seen that the feeding module 1 is arranged at the position corresponding to the input port 21, so that the UV glue coating module 3 is configured between the feeding module 1 and the input port 21 of the ultraviolet light adhesive curing light box 2, and the UV glue coating module 3 is located outside the input port 21; the receiving module 4 is configured outside the output port 22 of the ultraviolet light adhesive curing light box 2.

The adhesive substrate 51 can be a tape, a film (for example, a PET film) or a glass sheet; at the same time, the UV glue coating module 3 can first coat UV glue on the surface of the adhesive substrate 51 before the adhesive substrate 51 enters the input port 21, so that the adhesive substrate 52 coated with UV glue enters the ultraviolet light curing channel 20 from the input port 21.

The V-shaped protrusion at the bottom allows a predetermined angle 253 between the two ultraviolet lamp rows 252. Each ultraviolet light emitting unit 251 irradiates the adhesive substrate 52 in an oblique direction, so as to achieve the effect of allowing a single light source to irradiate a larger range. The predetermined angle 253 can be 140 degrees to 160 degrees, for example, 150 degrees. The distance between each V-shaped ultraviolet irradiator 25 and the ultraviolet curing channel 20 (adhesive substrate 52) can be 6 to 8 centimeters. Each ultraviolet light emitting unit 251 can be a ultraviolet light emitting diode.

[0031] Figure 5 As can be seen in the figure, the receiving module 4 can receive the adhesive substrate 53 provided with solid UV adhesive outputted from the output port 22. The adhesive substrate 53 provided with solid UV adhesive can be a tape, adhesive backing or a film (for example, a plastic film, a glass film), the tape can include an OCA tape, a double-sided adhesive tape, a protective film tape or a sealing tape, the adhesive backing can include an advertising sign film adhesive backing or a vehicle body film material adhesive backing, and the film can include a screen protection film.
