Description

Technical Field

[0001] This utility model relates to the field of fabric coating technology, and in particular to a flame-retardant fabric coating device with a guiding structure. Background Technology

[0002] Flame-retardant fabrics are fabrics that can prevent themselves from being ignited or delay and terminate combustion when in contact with flames or hot objects. In the processing of flame-retardant fabrics, coating devices are mostly used to evenly coat the flame retardant on the surface of the fabric to form a flame-retardant protective film, preventing oxygen from contacting the fabric, thereby achieving the purpose of flame retardancy.

[0003] Flame-retardant fabric coating equipment typically includes a fabric conveying mechanism, a coating mechanism, and a fabric drying mechanism. The fabric to be coated is moved smoothly and continuously to the coating area by the fabric conveying mechanism, the coating mechanism applies the flame retardant evenly to the fabric, and then the fabric enters the drying area for drying by the drying mechanism.

[0004] Currently, the spray head position of most coating devices is fixed, which may result in the fabric edges not being effectively coated.

[0005] The existing publicly available technical solution, announcement number CN222093774U, discloses a flame retardant coating device for flame retardant fabrics. By reciprocating the spray head, the flame retardant is effectively sprayed onto both sides of the fabric, ensuring that all parts of the fabric are effectively coated and avoiding situations where some parts such as the edges of the fabric are not effectively coated, thus ensuring the overall flame retardant effect of the fabric.

[0006] In actual implementation, the above technical solution only sprays the flame retardant fabric with a reciprocating spray head, without using a scraping mechanism to spread the flame retardant evenly on the fabric. This can easily lead to inconsistent spray thickness and affect the coating effect of the flame retardant. Summary of the Invention

[0007] The purpose of this invention is to provide a flame-retardant fabric coating device with a guiding structure, which can move the nozzle bracket and scraper by adjusting the lead screw. After the flame retardant is sprayed, the scraper flattens the flame retardant on the fabric, so that the thickness of the flame retardant is uniform, thereby solving the problems mentioned in the background art.

[0030] The lifting assembly 3 includes a lifting bracket 302 that is slidably installed inside the coating device body 1. An adjusting screw 304 is rotatably installed inside the lifting bracket 302, and a sliding member 305 is connected to the surface of the adjusting screw 304 through a threaded sleeve. A scraper 310 is fixed to the bottom of one set of sliding members 305, and a nozzle bracket 306 is fixed to the bottom of another set of sliding members 305. Multiple flame retardant nozzles 309 are fixed to the bottom of the nozzle bracket 306.

[0031] The lifting assembly 3 also includes a lifting cylinder 301 fixed to the top of the coating device body 1. The telescopic end of the lifting cylinder 301 passes through the coating device body 1 and is fixedly connected to the lifting bracket 302.

A flame retardant storage box 7 is fixedly connected to the input end of the connecting conduit 308. The end of the connecting conduit 308 is fixedly connected to the nozzle bracket 306.

[0032] By adopting the above technical solution, after the fabric to be processed enters the coating device body 1 through the fabric inlet 2, the lifting component 3 is adjusted according to the fabric thickness, and the lifting cylinder 301 is activated. The lifting cylinder 301 can push the lifting bracket 302 to slide on the lifting slide 303. At this time, the connecting conduit 308 passes through the lifting bracket 302 and is always fixedly connected to the nozzle bracket 306, moving the scraper 310 above the fabric. At this time, the flame retardant nozzle 309 is activated, and the flame retardant in the flame retardant storage tank 7 can be transported to the flame retardant nozzle 309 through the connecting conduit 308, and sprayed onto the fabric by the flame retardant nozzle 309. At this time, the lead screw is activated. The motor 307, a lead screw motor 307, can drive the adjusting lead screw 304 to rotate, thereby simultaneously driving the nozzle bracket 306 and the scraper 310 to move through the sliding member 305. The height of the scraper 310 can be adjusted as needed. When the scraper 310 moves, it can smooth the flame retardant on the fabric, making the flame retardant thickness uniform. The lifting component 3 can adjust the height of the nozzle bracket 306 and the scraper 310 according to the fabric thickness. In conjunction with the adjusting lead screw 304 driving the nozzle bracket 306 and the scraper 310 to move, after the flame retardant is sprayed, the scraper 310 smooths the flame retardant on the fabric, making the flame retardant thickness uniform.

[0033] Specifically, such as Figures 2 to 5 As shown, a correction component 4 is provided at the front end of the guide roller 6, and a cleaning component 5 is provided at the front end of the correction component 4.

[0036] By adopting the above technical solution, after the fabric is cleaned by the cleaning component 5, it reaches the position of the correction component 4. The correction component 4 adjusts the position of the fabric, and then it enters the coating device body 1 through the guide roller 6. When cleaning the fabric, the fabric is sandwiched between the support roller 501 and the cleaning brush 505. Rotating the adjusting screw 502 drives the limit slider 503 to slide up and down, adjusting the distance between the support roller 501 and the cleaning brush 505. As the fabric moves, the cleaning brush 505 can clean the lint and other particles on the fabric. The stepper motor 404 can drive the support bracket 402 to rotate, causing the guide slider 406 on the support bracket 402 to rotate inside the guide ring groove 405, thereby adjusting the angle of the support bracket 402. The coated fabric reaches the bottom of the drying component 8. The drying component 8 descends with the descent of the lifting bracket 302. The blower 802 blows the air heated by the heating rod 803 onto the fabric to dry it.

[0037] Working principle: The fabric is sandwiched between the support roller 501 and the cleaning brush 505. As the fabric moves, the cleaning brush 505 cleans lint and other debris from the fabric. The fabric enters the coating device body 1 through the guide roller 6. The lifting assembly 3 is adjusted according to the fabric thickness. The lifting cylinder 301 is activated, which pushes the lifting bracket 302 to slide on the lifting chute 303. At this time, the connecting conduit 308 passes through the lifting bracket 302 and is always fixedly connected to the nozzle bracket 306. The scraper 310 is moved above the fabric. At this time, the flame retardant nozzle 309 is activated, and the flame retardant storage tank 7... The flame retardant can be delivered to the flame retardant nozzle 309 through the connecting conduit 308, and sprayed onto the fabric by the flame retardant nozzle 309. At this time, the lead screw motor 307 is started, which can drive the adjusting lead screw 304 to rotate, thereby simultaneously driving the nozzle bracket 306 and the scraper 310 to move through the sliding member 305. The height of the scraper 310 can be adjusted as needed. When the scraper 310 moves, it can scrape the flame retardant on the fabric. The drying component 8 descends with the lowering bracket 302. The blower 802 blows the air heated by the heating rod 803 onto the fabric to dry the fabric.
