Description

Technical Field

[0001] This invention relates to the field of coating machine technology, specifically to a UV coating device with good uniformity. Background Technology

[0002] Coating machines are mainly used for surface coating processes on films, paper, etc. This machine coats a roll of substrate with a specific functional adhesive, paint, or ink, and then dries and rewinds it. It uses a dedicated multi-functional coating head to achieve various forms of surface coating. Brush coating machines are the oldest type of coating equipment. There are three different types of brush coating heads: rotary brush coating heads, blanket roller coating heads, and blanket-covered coating heads. UV coating liquids are applied to paper, cloth, and plastic films. Other methods include roller coating, spray coating, and powder coating. Coating is the process of applying coatings to workpieces, such as boards. Coating: For purposes such as corrosion prevention, insulation, and decoration, a thin plastic layer is applied in liquid or powder form to the surface of objects such as fabrics, paper, metal foil, or boards. Compared with other coating methods, spray coating has advantages such as good film quality, high coating efficiency, and uniform film thickness.

[0003] Although spraying produces a more uniform paint film thickness compared to other coating methods, its nozzle structure is complex, making it prone to clogging. It is also more expensive and requires frequent maintenance, which limits its widespread adoption. Furthermore, spraying consumes more paint than other coating methods, further increasing costs. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a UV coating device with good uniformity, comprising a base, a roll fixedly connected to the top of the base, the roll collecting the coated substrate, a roller frame fixedly connected to the end of the base away from the roll, a clamping roller fixedly connected to the top of the roller frame, a cleaning component fixedly connected to the side of the roller frame, the cleaning component cleaning the fabric surface before coating, a light-shielding box provided on the side of the cleaning component near the roll, the bottom of the light-shielding box being fixedly connected to the base via a bracket, a spraying component fixedly connected to the inner wall of the light-shielding box, a leveling component fixedly connected to the side of the inner wall of the light-shielding box near the roll, and a spraying component located below the leveling component. The system includes a support plate, the bottom of which is fixedly connected to a base. An ultraviolet lamp is fixedly connected to the side of the light-shielding box. A roller collects the coated substrate, and a clamping roller holds the substrate in the middle for auxiliary positioning. A cleaning component cleans the fabric surface beforehand to ensure the subsequent coating effect. Because UV coatings cure when exposed to ultraviolet light, spraying is performed inside the light-shielding box to prevent ultraviolet light from interfering with the coating process. The light-shielding box also contains a leveling component to level the substrate after coating, making the coating more uniform. It can also scrape off excess UV coating for collection and reuse, saving costs. An ultraviolet lamp is installed on the outside of the light-shielding box, allowing the substrate to cure under ultraviolet light after coating and leveling.

[0005] Furthermore, the spraying component includes a feed pipe, the outer surface of which is fixedly connected to a light-shielding box. A distribution pipe is fixedly connected to the bottom of the feed pipe, and the feed pipe and the distribution pipe are in communication. A UV coating is connected to the end of the feed pipe away from the distribution pipe. A nozzle is fixedly connected to the bottom of the distribution pipe, and a cleaning component is fixedly connected to the side of the nozzle. The UV coating enters the distribution pipe from the feed pipe, then enters the nozzle from the distribution pipe, and is atomized and sprayed out from the nozzle, resulting in a more uniform coating. When the machine is stopped, the cleaning component can be used to clean the nozzle to prevent coating accumulation and blockage.

[0006] Furthermore, the nozzle includes a spray cylinder, the top of which is fixedly connected to a distribution pipe, a conical cylinder fixedly connected to the inner wall of the spray cylinder, a solenoid valve fixedly connected to the side of the conical cylinder, a splash guard provided below the conical cylinder, the side of the splash guard fixedly connected to the spray cylinder, and a striker fixedly connected to the bottom of the splash guard. The UV coating enters the distribution pipe from the feed pipe, then enters the spray cylinder from the distribution pipe, and finally enters the conical cylinder from the spray cylinder. The conical cylinder is wider at the top and narrower at the bottom. The coating is sprayed out through the conical cylinder and atomized by impact with the striker, forming a mist coating for spraying, resulting in more uniform coating. The splash guard can prevent the coating that collides with the striker from splashing upwards into the conical cylinder and contaminating the coating inside the conical cylinder.

[0007] Furthermore, the impact pin includes a pin body, the top of which is fixedly connected to a splash guard via a connecting rod. A splash plate telescopic rod is fixedly connected to the inner wall of the pin body, and a connecting ear is fixedly connected to the bottom of the pin body. A splash plate is rotatably connected to the side of the connecting ear. A pry plate is rotatably connected to the end of the splash plate near the splash plate telescopic rod, and the end of the pry plate away from the splash plate is fixedly connected to the splash plate telescopic rod. The splash plate is horizontal during operation. After the UV coating impacts the pin body, it will further impact the splash plate, further atomizing it, making the water droplets smaller and the coating more uniform. When the impact pin needs to be cleaned, the extension and retraction of the splash plate telescopic rod can drive the pry plate to rise and fall, causing the splash plate to rotate around the connecting ear, thereby changing the angle between the splash plate and the pin body, so that every point on its surface can be cleaned, ensuring the cleaning effect, preventing coating accumulation and clogging, and extending the service life of the device.

[0008] Furthermore, the cleaning component includes a water inlet pipe, the outer surface of which is fixedly connected to a light-shielding box. A water distribution pipe is fixedly connected to the side of the water inlet pipe, and the water inlet pipe and the water distribution pipe are connected in communication. The end of the water inlet pipe away from the water distribution pipe is connected to a water source. A flexible hose is fixedly connected to the bottom of the water distribution pipe, and the water distribution pipe and the flexible hose are connected in communication. A water spray ring is fixedly connected to the bottom of the flexible hose, and the flexible hose and the water spray ring are connected in communication. The side of the water spray ring is slidably connected to a spray cylinder. A cleaning telescopic rod is fixedly connected to the top of the water spray ring, and the top of the cleaning telescopic rod is fixedly connected to the spray cylinder. Spray holes are opened on the inner wall of the water spray ring. Clean water enters the water distribution pipe from the water inlet pipe, enters the flexible hose from the water distribution pipe, enters the water spray ring from the flexible hose, and is sprayed out from the spray holes on the water spray ring. The cleaning telescopic rod can extend and retract, driving the water spray ring to move up and down. The water spray ring sprays water around the needle body, cleaning the needle body and the splash plate from all directions, ensuring the cleaning effect, preventing paint accumulation and clogging, and extending the service life of the device.

[0009] Furthermore, the leveling component includes an arc-shaped scraper, the side of which is slidably connected to a light-shielding box. A scraper extension rod is fixedly connected to the top of the arc-shaped scraper, and the top of the extension rod is fixedly connected to the light-shielding box. An absorption box is fixedly connected to the side of the arc-shaped scraper, and a connecting pipe is fixedly connected to the top of the absorption box. The absorption box and the connecting pipe are in communication. A suction tube is slidably connected to the top of the connecting pipe, and the connecting pipe and the suction tube are in communication. The end of the suction tube away from the connecting pipe passes through the light-shielding box and is fixedly connected to a collection box. A water pump is fixedly connected to the outer surface of the suction tube, and the water pump is in communication with the suction tube. After the substrate is coated... When the scraper moves out of the light-shielding box, the curved scraper moves relative to the substrate surface, smoothing the surface and making the coating more even and uniform. Simultaneously, the extension and retraction of the scraper's telescopic rod raises and lowers the curved scraper, adjusting the gap between it and the substrate to control the coating thickness. It also scrapes away excess coating. The pump connects to a suction pipe, which in turn connects to the absorption box. The pump creates negative pressure in the absorption box, drawing excess coating scraped by the curved scraper into the absorption box, then through the pipe and suction pipe into the collection box. This completes the collection of excess coating, which can then be reused for coating, saving production costs.

[0010] Furthermore, the cleaning component includes a cleaning box, the side of which is fixedly connected to the roller frame via a connecting plate. A dust suction pipe is fixedly connected to the top of the cleaning box, and the cleaning box is connected to the dust suction pipe. A dust collection box is fixedly connected to the bottom of the dust suction pipe, and the dust suction pipe is connected to the dust collection box. A dust collection bag is fixedly connected to the inner wall of the dust collection box. An exhaust pump is installed below the dust collection bag, and the top of the exhaust pump is fixedly connected to the dust collection box, and the exhaust pump is connected to the dust collection box. The cleaning box cleans the surface of the substrate. Under the action of the exhaust pump, the dust is sucked into the dust collection box through the dust suction pipe and enters the dust collection bag. Before coating, the surface of the substrate is cleaned to make it clean and smooth, ensuring the coating effect and making the coating more uniform.

[0011] Furthermore, the cleaning box includes a housing, the side of which is fixedly connected to the roller frame via a connecting plate. A cleaning brush is rotatably connected to the inner wall of the housing. A cleaning motor is fixedly connected to one end of the cleaning brush. The side of the cleaning motor is fixedly connected to the roller frame via a connecting plate. A cleaning plate is provided above the cleaning brush. The side of the cleaning plate is fixedly connected to the housing. The cleaning motor drives the cleaning brush to rotate, cleaning the surface of the substrate and cleaning the dust onto the cleaning brush. Dust that cannot be completely adsorbed will also be lifted up by the cleaning brush.

[0012] Furthermore, the cleaning plate includes an arc-shaped plate, the side of which is fixedly connected to the outer shell, and a scraper is fixedly connected to the bottom of the arc-shaped plate. A dust-absorbing groove is formed on the surface of the arc-shaped plate. The cleaning motor drives the dust-absorbing cleaning brush to rotate and contact the scraper. The scraper scrapes the dust from the dust-absorbing groove into the cleaning box, where it is absorbed into the dust collection box and finally collected into the dust collection bag. This cleaning process cleans the surface of the substrate before coating, making its surface clean and smooth, ensuring the coating effect and making the coating more uniform. At the same time, the scraper cleans the cleaning brush, keeping it clean and ensuring the cleaning effect, further ensuring the coating effect and extending the service life of the device.

[0013] This invention provides a UV coating device with good uniformity. It has the following beneficial effects:

[0014] 1. This UV coating device with good uniformity is equipped with a spraying component. The UV coating enters the distribution pipe from the feed pipe, enters the nozzle from the distribution pipe, and is atomized and sprayed out from the nozzle, which is sprayed onto the substrate in an atomized manner, resulting in more uniform coating. When the machine is not in operation, the nozzle can be cleaned by the cleaning component set in the spraying component to prevent coating accumulation and blockage, and extend the service life of the device.

[0015] 2. This UV coating device with good uniformity is equipped with a nozzle. The UV coating enters the distribution pipe from the feed pipe, then enters the spray cylinder from the distribution pipe, and finally enters the conical cylinder from the spray cylinder. The conical cylinder is wider at the top and narrower at the bottom. The coating is sprayed out through the conical cylinder and atomized by impact with the impact needle, forming a mist coating for spraying, resulting in more uniform coating. The water splash plate is horizontal during operation. After the UV coating impacts the needle, it will further impact the water splash plate, further atomizing it, making the water droplet diameter smaller and the coating more uniform.

[0016] 3. This UV coating device with good uniformity is equipped with a cleaning component. Clean water enters the water distribution pipe from the inlet pipe, then enters the flexible hose, and finally enters the spray ring. The water is then sprayed out from the nozzles on the spray ring. The cleaning telescopic rod can extend and retract, causing the spray ring to move up and down. The spray ring sprays water around the needle body, cleaning the needle body and the splash plate thoroughly. At the same time, the splash plate telescopic rod extends and retracts, causing the rocker plate to rise and fall, and causing the splash plate to rotate around the connecting ear. This changes the angle between the splash plate and the needle body, ensuring that every point on its surface is cleaned, guaranteeing the cleaning effect, preventing coating accumulation and clogging, and extending the service life of the device.

[0017] 4. This UV coating device with good uniformity is equipped with a leveling component. When the substrate is finished spraying and moves out of the light-proof box, the arc-shaped scraper moves relative to the substrate surface, leveling the surface and making the coating smoother and more uniform. At the same time, the extension and retraction of the scraper rod can drive the arc-shaped scraper to rise and fall, adjusting the gap between the arc-shaped scraper and the substrate, controlling the coating thickness, and scraping off excess coating. The pump is connected to the suction pipe, which is connected to the absorption box through a connecting pipe. The pump creates negative pressure in the absorption box, sucking the excess coating scraped by the arc-shaped scraper into the absorption box, and then into the collection box through the connecting pipe and suction pipe, completing the collection of excess coating. After recycling, it can be reused for coating, saving production costs.

[0018] 5. This UV coating device with good uniformity is equipped with a cleaning component. A cleaning motor drives a cleaning brush to rotate, cleaning the substrate surface and removing dust. Dust that cannot be completely absorbed is also lifted by the cleaning brush. The cleaning motor drives the dust-absorbing cleaning brush to rotate and contact the scraper. The scraper scrapes the dust from the dust suction trough into the cleaning box, where it is absorbed into the dust collection box. At the same time, the dust lifted by the cleaning brush is also sucked into the dust collection box and finally collected into the dust collection bag. Before coating, the substrate surface is cleaned to make it clean and smooth, ensuring the coating effect and making the coating more uniform. At the same time, the scraper cleans the cleaning brush, keeping it clean and ensuring the cleaning effect, further ensuring the coating effect and extending the service life of the device.

The clamping roller 82 clamps the substrate in the middle to help position the substrate. The cleaning component 9 cleans the fabric surface in advance to ensure the subsequent coating effect. Because the UV coating will cure when exposed to ultraviolet light, it is sprayed in the light-shielding box 3 to prevent ultraviolet light from irradiating the coating area and interfering with the coating. The light-shielding box 3 is also equipped with a leveling component 7, which is used to level the substrate after coating to make the coating more uniform. At the same time, it can scrape off the UV coating on the surface, collect it and reuse it to save costs. The ultraviolet lamp 6 is set on the outside of the light-shielding box 3. After the substrate is coated and leveled, it is irradiated by the ultraviolet lamp 6 to complete the curing.

[0034] The spraying component 4 includes a feed pipe 41, the outer surface of which is fixedly connected to the light shield box 3. A distribution pipe 42 is fixedly connected to the bottom of the feed pipe 41, and the feed pipe 41 and the distribution pipe 42 are connected. The end of the feed pipe 41 away from the distribution pipe 42 is connected to UV coating. A nozzle 43 is fixedly connected to the bottom of the distribution pipe 42, and a cleaning component 44 is fixedly connected to the side of the nozzle 43. The UV coating enters the distribution pipe 42 from the feed pipe 41 and then enters the nozzle 43 from the distribution pipe 42.

The end of the pry plate 4345 away from the splash plate 4344 is fixedly connected to the splash plate telescopic rod 4342. When in operation, the device is horizontal. After impacting the needle body 4341, the UV coating will further impact the splash plate 4344, further atomizing it, making the water droplets smaller and the coating more uniform. When it is necessary to clean the needle 434, the extension and retraction of the splash plate telescopic rod 4342 can drive the rocker to rise and fall, causing the splash plate 4344 to rotate around the connecting ear 4343, thereby changing the angle between the splash plate 4344 and the needle body 4341, so that every point on its surface can be cleaned, ensuring the cleaning effect, preventing the coating from accumulating and clogging, and extending the service life of the device.

The water spray ring 444 sprays water around the needle body 4341, cleaning the needle body 4341 and the splash plate 4344 from all directions, ensuring the cleaning effect, preventing paint accumulation and clogging, and extending the service life of the device.

[0038] In use, the roll 2 collects the coated substrate and provides power for its movement. The clamping roller 82 assists in holding the substrate. The substrate is sprayed in the light-shielding box 3. The UV coating enters the distribution pipe 42 from the feed pipe 41, then the spray cylinder 431, and finally the conical cylinder 432. The conical cylinder 432 is wider at the top and narrower at the bottom. The coating is sprayed out through the conical cylinder 432 and atomized by impact with the impact needle 434. The water splash plate 4344 is horizontal during operation. After impacting the needle 4341, the UV coating further impacts the water splash plate 4344, further atomizing it.
