Technical Field

[0001] The utility model relates to the technical field of coating coating devices, in particular to a flame retardant functional coating uniform coating device. Background Art

[0002] Conventional fabrics will burn in high temperature environments or when exposed to open flames, losing their basic functions and even causing harm. In order to adapt to use in high temperature or open flame environments, flame retardant fabrics came into being.

[0003] A search has revealed a patent application in China with the publication number CN 220941492 U, which describes a flame-retardant coating device. The device, which belongs to the technical field of coating devices, comprises a housing; a coating roller, a pressure roller, a scraper, and a drying mechanism arranged in sequence within the housing according to the direction of the fabric; a coating box located on top of the coating roller; the pressure roller comprises an upper roller and a lower roller; the upper roller is positioned above the fabric; the lower roller is positioned below the fabric; and the scraper is positioned within the housing via a lifting mechanism. The lifting mechanism is used to raise and lower the scraper, thereby varying the distance between the scraper and the fabric, allowing for adjustment to fabrics of varying thicknesses, thereby improving the applicability of the coating device.

[0004] The fabric coating device in the above patent still has certain shortcomings. When the existing flame-retardant fabric coating device is actually used, the coating used is often uneven due to the uneven liquid discharge from the discharge pipe, which leads to uneven distribution of the coating liquid adhering to the bristles, thereby making the flame-retardant coating applied on the fabric uneven, affecting the quality of the product.

[0026] The flame retardant coating uniform coating assembly 5 includes a coating roller 501 arranged directly above the first feeding roller 4, one end of the coating roller 501 is rotatably connected to the inner wall of the coating bin 3, and the other end of the coating roller 501 rotates through the inner wall of the coating bin 3, and a first drive motor 502 is provided on the outside of the coating bin 3, and the drive shaft of the first drive motor 502 is fixedly connected to the end of the coating roller 501, and a coating spreading roller 503 is provided on the side of the coating roller 501, one end of the coating spreading roller 503 is rotatably connected to the inner wall of the coating bin 3, and the other end of the coating spreading roller 503 rotates through the inner wall of the coating bin 3, and a second drive motor 504 is provided on the outside of the coating bin 3.

[0027] The driving shaft of the second driving motor 504 is fixedly connected to the end of the paint spreading roller 503, and a paint storage bin 505 is provided on the top wall of the coating bin 3. A feeding pipe 506 is provided in the middle of the top of the paint storage bin 505, and the top of the feeding pipe 506 passes through the top of the coating bin 3. Several suction pumps 507 are evenly arranged at the bottom of the paint storage bin 505, and the input end of the suction pump 507 is connected to the bottom of the paint storage bin 505 through the connected upper connecting pipe 508, and the output end of the suction pump 507 is connected to the lower connecting pipe 509, and a paint liquid nozzle 510 is installed at the bottom of the lower connecting pipe 509, and a first valve 511 is provided on the paint liquid nozzle 510, and the side of the lower connecting pipe 509 is connected to the residual liquid discharge pipe 512, and a second valve 513 is provided on the residual liquid discharge pipe 512.

[0028] Embodiment 2: The difference between this embodiment and embodiment 1 is that a closing cover is provided at the top end of the feed pipe 506 .

[0029] The top of the feed pipe 506 is closed to prevent the flame retardant coating liquid added to the coating storage tank 505 from condensing.

[0030] Embodiment 3: The difference between this embodiment and embodiment 1 is that the paint spreading roller 503 is located on the side close to the paint roller 501.

[0031] The coating liquid dripping between the coating roller 501 and the coating spreading roller 503 can be pushed to one side of the coating roller 501 under the continuous rotation of the coating roller 501 and the coating spreading roller 503, so that the coating roller 501 can evenly coat the upper surface of the fabric that bypasses the surface of the first feeding roller 4 with flame retardant coating.

[0032] Embodiment 4: The difference between this embodiment and embodiment 1 is that the coating liquid nozzle 510 is located between the coating roller 501 and the coating spreading roller 503 .

[0033] The flame retardant coating liquid discharged through the coating liquid nozzle 510 can fall to the side of the coating roller 501 near the coating spreading roller 503. Through the opposite rotation of the coating spreading roller 503 and the coating roller 501, the coating liquid can be better and more evenly adhered to the coating roller 501.

[0034] In this embodiment, since the existing flame retardant fabric coating device is often used in actual use, the coating used for coating is often unevenly distributed due to the uneven liquid discharge from the discharge pipe, which leads to uneven distribution of the coating liquid adhering to the bristles, thereby making the flame retardant coating applied to the fabric uneven, affecting the quality of the product.

[0035] In summary, in specific implementation, when the user needs to apply flame retardant paint to the surface of the fabric, the user first needs to pass the fabric around the top of the second feeding roller 6 and the bottom of the third feeding roller 7 in turn, and wrap it around the upper surface of the first feeding roller 4. The gap between the first feeding roller 4 and the coating roller 501 can allow the fabric to pass through, and the upper surface of the fabric can be contacted by the coating roller 501.

[0036] Next, the user can simultaneously start several suction pumps 507 evenly arranged below the paint storage bin 505, so that the suction pumps 507 suck the flame retardant coating liquid in the paint storage bin 505 through the upper connecting pipe 508, and then transport it to the paint liquid nozzle 510 through the lower connecting pipe 509, so that the paint liquid nozzle 510 can drop the flame retardant coating liquid onto the side surface of the paint roller 501 close to the paint spreading roller 503, and since the gap between the several paint liquid nozzles 510 is small, the coating liquid drips onto the paint roller 501.

[0037] Under the forward rotation of the coating roller 501 and the reverse rotation of the coating spreading roller 503, the flame retardant liquid dripping onto the surface of the coating roller 501 can be quickly spread out, so that the coating liquid can quickly and evenly adhere to the coating roller 501, and then the coating roller 501 can more evenly apply the flame retardant coating liquid on the fabric, thereby making the coated product higher in quality.
