[0034] The following is in conjunction with the appendix Figures 1 to 7 The present invention will be described in further detail, but this is not intended to limit the scope of the present invention.

[0035] like Figure 1As shown, in one embodiment of this utility model, the UV curing machine for coating includes a feeding device 100, a coating device 200, a material conveying device 700, a drying device 300, a UV curing device 400, and a cooling device 500. The feeding device 100, coating device 200, and material conveying device 700 are arranged sequentially, and the output end of the feeding device 100 is connected to the input end of the coating device 200; the output end of the coating device 200 is connected to the input end of the material conveying device 700; the drying device 300, UV curing device 400, and cooling device 500 are arranged sequentially in the conveying direction of the material conveying device 700. UV light is an abbreviation for ultraviolet rays, a type of electromagnetic radiation. Its position in the electromagnetic spectrum is between visible light and X-rays.

[0036] The technical solution of this utility model uses a drying device to perform preliminary drying treatment on the coated material, and then uses a UV curing device to cure the pre-dried material by UV light irradiation. This can improve the quality of the coated part of the material and increase production efficiency. In addition, the sequential assembly of the feeding device, coating device, and drying device and UV curing device set on the material conveying device can improve the overall compactness and smoothness of operation of the equipment, thereby improving production efficiency and product quality, and reducing production costs and operating difficulty.

[0037] Specifically, in some implementations, such as Figure 1 , 2 As shown in Figure 7, the material conveying device 700 includes a first horizontal conveying section 720, an inclined conveying section 710, and a second horizontal conveying section 730 arranged sequentially. The input end of the first horizontal conveying section 720 is connected to the output end of the coating device 200. The first horizontal conveying section 720 is located below the second horizontal conveying section 730. The drying device 300 and the UV curing device 400 are arranged sequentially above the second horizontal conveying section 730. This structure, through the first horizontal conveying section 720, the inclined conveying section 710, and the second horizontal conveying section 730 with a height difference, allows excessively thick coating areas on the material after preliminary drying to flow backward, forming a relatively uniform coating layer. This improves production efficiency and product quality, and reduces manual adjustment operations.

[0038] In some implementation methods, such as Figure 7As shown, the angle between the inclined conveyor section 710 and its horizontal direction is α; α satisfies: 30°≤α≤60°. α can be 30°, 40°, 45°, 50°, 60°, etc. This structure, through a suitable acute angle of inclination, ensures that excessively thick coating areas on the material after preliminary drying flow backward to form a relatively uniform coating layer; it also avoids excessive coating layer offset due to an excessively large angle, and avoids the inability to adjust the offset due to an excessively small angle; thereby improving production efficiency and product quality, and reducing manual adjustment operations.

[0039] Specifically, in some implementations, such as Figure 1 , 2 As shown in Figure 7, the material conveying device 700 includes at least two upper conveying rollers 701 and at least two lower conveying rollers 702; each upper conveying roller 701 and each lower conveying roller 702 are arranged side by side, and a conveying channel is provided between each upper conveying roller 701 and each lower conveying roller 702; and each upper conveying roller 701 and each lower conveying roller 702 are arranged sequentially at equal intervals along the conveying direction; the drying device 300 and the UV curing device 400 are arranged above the upper conveying rollers 701. The parallel arrangement of the upper conveying rollers 701 and lower conveying rollers 702 ensures smooth conveying and avoids material lifting; and the assembly gap between adjacent upper conveying rollers 701 improves the speed of preliminary drying and UV curing, thereby improving operational smoothness and efficiency. The upper conveying rollers 701 or lower conveying rollers 702 are driven by a drive motor.

[0040] Specifically, in some implementations, such as Figure 1 and 2 As shown, the drying device 300 includes at least one infrared drying lamp 310; the infrared drying lamps 310 are arranged equidistantly along the conveying direction of the material conveying device 700 (the first horizontal conveying section 720), and are positioned above the material conveying device 700 (the first horizontal conveying section 720). Wherein, as... Figure 2 As shown, there are twenty infrared drying lamps 310 arranged in an array at equal intervals. Furthermore, the infrared drying lamp 310 (quartz infrared lamp) is a highly efficient heat source, featuring a quartz bulb and tungsten filament, which prevents the tube wall from blackening and the resulting decrease in luminous flux. The advantages of the infrared drying lamp 310 include: high efficiency, rapid heat transfer, sensitive response to control devices, compact structure, and light weight.

[0041] Specifically, in some implementations, such as Figure 1 and 2As shown in Figure 7, the UV curing device 400 includes at least one UV curing lamp 410; the UV curing lamps 410 are arranged equidistantly along the conveying direction of the material conveying device 700 (the second horizontal conveying section 730), and are positioned above the material conveying device 700 (the second horizontal conveying section 730). This structure, through the energy-efficient electronic power supply and the arrangement of high-power UV curing lamps 410 (UV lamp tubes), enables UV light to uniformly irradiate local areas of the material; thereby improving production efficiency and product quality, and reducing production costs and operational difficulty.

[0042] Specifically, in some implementations, such as Figure 1 , 2 As shown in Figure 3, the feeding device 100 includes a height adjustment component 110, a material placement plate 120, an adsorption and transfer component 130, an extrusion and correction component 140, a first support 170, and a feeding conveying component 150.

The material placement plate 120 is connected to the height adjustment component 110 and is used to perform cyclic movement along the height direction of the first support 170. The adsorption and transfer component 130 is connected to the first support 170 and is arranged above the material placement plate 120. The adsorption and transfer component 130 is used to adsorb the material on the material placement plate 120 to the input end of the feeding conveying component 150. In some embodiments, the adsorption transfer component 130 is a power structure combining an adsorption transfer cylinder and a suction cup; or the adsorption transfer component 130 is a power structure combining a robotic arm and a suction cup. In some embodiments, the height adjustment component 110 is a power source formed by a height adjustment cylinder or a height adjustment screw. Further, the height adjustment component 110 and the adsorption transfer component 130 form a feeder head structure.

This structure allows for the extrusion rubber contact surface and the extrusion brush-like contact surface to achieve the feeding and flattening operation of the conveying material and to clean some of the dust and other structural components on the surface of the material, thereby ensuring coating quality and smooth operation.

[0044] Specifically, in some implementations, such as Figure 3and 4 As shown, the feeding and conveying component 150 includes a first conveyor belt 153, at least one first guide roller 160, and at least two first rotating shafts 152.

This structure, through the conveying action of the first conveyor belt 153 with suction holes 151, ensures that the material remains stable and does not deviate during high-speed transmission, and achieves smoother conveying. One of the first rotating shafts 152 is driven by a drive motor.

[0045] Specifically, in some implementations, such as Figure 1 , 2 As shown in Figure 5, the coating apparatus 200 includes a transfer roller 210, a third rotating roller 220, an anilox coating roller 230, a second support 270, a scraping component 240, a coating extrusion roller 250, and a coating conveying component 260; the transfer roller 210 is connected to the second support 270 and communicates with the output end of the feeding device 100 (the middle feeding conveying component 150); the third rotating roller 220 is connected to the second support 270 and is disposed on the transfer roller 210. Above; the anilox coating roller 230 is connected to the second support 270 and positioned above the third rotating roller 220; the scraper component 240 is connected to the second support 270 and positioned to the side of the anilox coating roller 230 in the direction of rotation; the coating extrusion roller 250 is connected to the second support 270 and positioned below the third rotating roller 220; the coating conveying component 260 is connected to the second support 270 and positioned below the coating extrusion roller 250. That is, the material rotates in from above the transfer roller 210, then passes above the third rotating roller 220 and is conveyed to the anilox coating roller 230; after being coated by the coating nozzle above the anilox coating roller 230, it is then scraped evenly by the scraper component 240; immediately afterward, it is conveyed diagonally below the third rotating roller 220 and, under the extrusion and shaping action of the coating extrusion roller 250, is conveyed to the coating conveying component 260. Wherein, as... Figure 5 As shown, the surface of the third rotating roller 220 is provided with a rubber sheet layer 221.

A material storage cavity 245 is formed between the upper scraper 242, the lower scraper 243, and the connecting side plate 244. The other ends of the upper scraper 242 and the lower scraper 243 both extend towards the anilox coating roller 230. The transverse drive 241 is connected to the side of the connecting side plate 244 away from the material storage cavity 245.

That is, after UV curing, the conveyor belt restarts, transporting the processed material to the end of the equipment for cooling and receiving, thus achieving its collection and sorting. Furthermore, after completing one processing cycle, the equipment automatically prepares for the next processing cycle, continuously repeating the above steps to achieve efficient and continuous localized UV processing production. In some embodiments, such as... Figure 1 , 2As shown in Figure 7, the cooling device 500 includes a cooling protective cover 510 and at least one cooling fan 520.

Furthermore, the projection of the cooling coverage surface of the cooling fan 520 towards the material conveying device 700 is larger than the conveying coverage portion of the material conveying device 700 within the cooling protective cover 510. Further, the number of cooling fans 520 is at least four, arranged equidistantly side-by-side. The cooling device 500 uses a metal cover with a cross-section of a frustum or truncated cone to improve heat dissipation and cooling efficiency. That is, by using a group of cooling fans 520 with a larger cooling coverage area, the material temperature can be rapidly reduced after UV curing, preventing material deformation or damage due to high temperatures; thereby improving production quality and efficiency.
