The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0024] like Figure 1 、 Figures 3 to 6 As shown, this is Example 1 of the utility model, an improved paint light curing production line, comprising an electrostatic dust removal device 6, an automatic paint spraying device 7, a baking oven 8 and a light curing device 1 arranged in sequence, the electrostatic dust removal device 6, the automatic paint spraying device 7, the baking oven 8 and the light curing device 1 are respectively provided with an automatic feeding belt 9, the light curing device 1 comprises a first curing box 11 and a second curing box 12, the first curing box 11 is provided with a heating lamp group 2 for heating the material on the automatic feeding belt 9, the second curing box 12 is provided with a light curing lamp group 3 and a plurality of lifting rails 4 for realizing the up and down movement of the light curing lamp group 3, the light curing lamp group 3 is used to perform light curing on the material on the automatic feeding belt 9, and the heating lamp group 2 and the light curing lamp group 3 are both arranged on the upper and lower sides of the automatic feeding belt 9.

[0025] Furthermore, the heating lamp group 2 includes a plurality of LED lamps 21, which are distributed on the upper and lower sides of the automatic feeding belt 9. Specifically, during use, the paint-coated material is transferred to the first curing box 11 via the automatic feeding belt 9, and the paint on the surface of the material is heated by the LED lamps 21 of the first curing box 11. However, the material is usually painted on both the top and bottom surfaces. Therefore, by distributing the LED lamps 21 on the upper and lower sides of the automatic feeding belt 9, the paint on both sides of the material can be better heated and kept warm, which expands the scope of use, better avoids the paint from cooling and forming undesirable clots, and achieves the initial curing of the paint.

[0026] Furthermore, the light-curing lamp assembly 3 includes a plurality of UV lamps 31, which are distributed on both sides of the automatic feeding belt 9. Specifically, after the paint is heated, the automatic feeding belt 9 conveys the material to the second curing box 12, where the UV lamps 31 light-cure the heated paint at a suitable temperature. However, the material is usually painted on both the top and bottom surfaces. Therefore, by distributing the UV lamps 31 on both sides of the automatic feeding belt 9, the paint on both sides of the material can be better cured, further expanding the scope of use. At the same time, it avoids the need to turn the material over to cure the other side after curing the paint on both sides, thereby improving production efficiency.

[0027] Furthermore, support rods 32 are provided on both sides of the ultraviolet lamp 31 and are slidably matched with the lifting rails 4.

[0028] Furthermore, a plurality of fixed beams 121 are provided in the second curing box 12 , and the tops of the plurality of lifting rails 4 are fixed to the fixed beams 121 .

[0029] Furthermore, the lifting rail 4 includes a sliding portion 41 and a plurality of slots 42 distributed longitudinally along the sliding portion 41. Specifically, the height of the UV lamp 31 can be adjusted to control the area of ​​UV irradiation and the curing speed of the paint to ensure the quality of paint curing. During adjustment, the support rods 32 on both sides of the UV lamp 31 are slid within the sliding portion 41. When the UV lamp 31 is adjusted to the appropriate height, the support rods 32 on both sides of the UV lamp 31 are engaged in the slots 42 to secure the UV lamp 31.

[0030] Furthermore, ventilation fans 5 are provided on the tops of the first curing box 11 and the second curing box 12 .

[0031] Working principle: When in use, the material is dusted by the electrostatic dust removal box 6, and then automatically sprayed with paint by the automatic paint spraying device 7. After high-temperature baking in the baking furnace 8, the painted material is transferred to the first curing box 11 by the automatic feeding belt 9. The paint on the surface of the material is heated by the heating lamp group 2 of the first curing box 11 to maintain the temperature of the paint and avoid poor solidification of the paint due to cooling. At the same time, the paint is initially cured. After the paint is heated, the material is transferred to the second curing box 12 by the automatic feeding belt 9. The paint with a suitable temperature after heating is light-cured by the light curing lamp group 3 to achieve a good curing effect. At the same time, the heating lamp group 2 and the light curing lamp group 3 are arranged on the upper and lower sides of the material, and the upper and lower sides of the material are heated and light-cured at the same time, thereby improving production efficiency.

According to the direction of material advance, one automatic paint spraying device 7 is provided after the electrostatic dust removal device 6, and the other automatic paint spraying device 7 is provided in the middle of the baking oven 8. The advantage of providing two automatic paint spraying devices 7 is that after the material undergoes the first painting and the high-temperature baking in the baking oven 8, it undergoes the second painting according to the requirements of the material painting process, and after the material undergoes the high-temperature baking in the baking oven 8 again, it enters the light curing device 1 for curing. The other structures of this embodiment are the same as those of Example 1 and will not be repeated here.
