Description

Technical Field

[0001] This utility model relates to the field of aramid fabric surface coating, and in particular to a coating device for anti-aging treatment of aramid fabric surface. Background Technology

[0002] Aramid fabric, with its superior high strength, high modulus, high temperature resistance, and chemical corrosion resistance, occupies an important position in many high-end fields such as aerospace, defense, and transportation. For example, in the aerospace field, aramid fabric is used to manufacture key structural components of aircraft, which can effectively reduce aircraft weight and improve fuel efficiency and flight performance; in defense, it is a core material for making high-performance bulletproof equipment, providing a solid guarantee for personnel safety.

[0003] In existing anti-aging coating operations for aramid fabrics, traditional spraying mechanisms commonly suffer from fixed nozzle positions. During production and subsequent transport, aramid fabrics are not perfectly smooth due to variations in raw material properties, complex manufacturing processes, and stress during mechanical transport; they often exhibit fine wrinkles, inconsistent thickness, and irregular textures. Fixed nozzle positions cannot flexibly adapt to these real-time changes on the aramid fabric surface. In wrinkled areas, the folds caused by the wrinkles result in insufficient coverage of the anti-aging coating. This severely uneven coating distribution significantly weakens the overall anti-aging protective performance of the aramid fabric, making it difficult to meet industry application standards with extremely high material reliability requirements.

[0025] like Figure 4 As shown, the pressing mechanism 4 includes a support frame 401. A transmission rod 402 and a transmission rod 403 are provided between a pair of support frames 401.

[0026] like Figure 5As shown, the winding mechanism 5 includes an electric motor 501, the output end of which is connected to a magnetic connector sleeve 502. A switch support block 503 is provided on the support rail 2. A winding roller 504 is movably disposed inside a pair of switch support blocks 503. A pair of clamps 505 are provided on the winding roller 504. One end of the winding roller 504 is engaged with the magnetic connector sleeve 502.

[0027] like Figures 1-5 As shown, the programmable controller 7 is electrically connected to motor 404, electric motor 1 301-1, electric motor 2 302-6, electric motor 3 302-7, electric motor 4 501, and pressurized fan 302-13.

[0028] In practice, one end of the aramid fabric is first placed on the pressing mechanism 4 on the side equipped with the winding mechanism 5, so that the aramid fabric is positioned between the two pressing rollers 407. The motor 404 in the pressing mechanism 4 is started, and the output end of the motor 404 drives the transmission rod 402 to rotate. The gear 405 on the transmission rod 402 meshes with the gear 406 on the transmission rod 403, thereby causing the transmission rod 403 to rotate synchronously. The two pressing rollers 407 rotate in opposite directions, removing the wrinkles on the surface of the aramid fabric and pressing the aramid fabric tightly and conveying it forward.

[0029] The motion spraying mechanism 3 plays a crucial role in this process. Its unique design allows the operator to easily perform anti-aging spraying on specific areas of the aramid fabric, both front and back. When spraying is required on the aramid fabric, the operator can flexibly control the operation of electric motors 301-1, 302-6, and 302-7 via the programmable controller 7. Electric motor 301-1 drives screw 301-2 to rotate, causing the moving plate 301-3 to move longitudinally along the support guide rail 2, thus determining the longitudinal position to be sprayed. Electric motors 302-6 and 302-7 respectively drive screws 302-4 and 302-5 to rotate, causing moving blocks 302-8 and 302-9 to move laterally with the spray nozzle 302-10, precisely positioning the area of ​​the aramid fabric to be sprayed. During this process, the spraying speed and direction of the nozzle can be adjusted to spray specific areas on the front or back of the aramid fabric. This method greatly saves paint, avoids wasting paint on areas that do not need to be sprayed, and allows the operator to focus on fine spraying of local areas, thus improving the spraying effect.

[0030] After the spraying mechanism moves to the designated position, the anti-aging coating in the loading cylinder 302-12 is injected into the coating pipe 302-11 by the pressurized blower 302-13 through the liquid-gas conveying device 302-15 and the distributor 302-14, and finally sprayed out from the spray nozzle 302-10, evenly coating the surface of the aramid fabric. The pressure generated by the pressurized blower 302-13 ensures that the coating can be stably and efficiently delivered to the spray nozzle 302-10. During the spraying process, the motion spraying mechanism 3 operates continuously according to the programmable controller 7 to achieve more uniform spraying on both sides of the aramid fabric.

[0031] After the aramid fabric completes one coating stage, it undergoes further smoothing via a second pressing mechanism 4 to prevent product damage due to wrinkles during winding. Subsequently, the programmable controller 7 starts the electric motor 501. The magnetic connector 502 at the output of the electric motor 501 engages with one end of the winding roller 504, causing the winding roller 504 to rotate. Simultaneously, the clamp 505 on the winding roller 504 grips the coated end of the aramid fabric. As the winding roller 504 rotates, the aramid fabric coated with the anti-aging paint is wound up, completing the winding process.
