[0024] In a further preferred embodiment of this utility model, the automatic coating mechanism includes a storage tank 9, a feeding pump 10, an inlet pipe 11, an outlet pipe 12, two spray pipes 13, and multiple spray heads 14. The storage tank 9 is fixedly installed on the top of the dustproof box 2. The feeding pump 10 is fixedly installed on one side of the storage tank 9. The inlet end of the feeding pipe 11 extends into the storage tank 9, and the outlet end of the feeding pipe 11 is fixedly connected to the inlet end of the feeding pump 10. The inlet end of the outlet pipe 12 is fixedly installed on the outlet end of the feeding pump 10, and the outlet end of the outlet pipe 12 extends into the dustproof box 2. Both spray pipes 13 are fixedly connected to the outlet pipe 12. The two spray pipes 13 are located above and below the woven fabric, respectively. The multiple spray heads 14 are respectively disposed on the two spray pipes 13.

[0025] In this embodiment, the storage tank 9 is fixedly installed on the top of the dustproof housing 2 for storing coating materials. The feed pump 10 is fixedly installed on one side of the storage tank 9 for drawing the coating materials from the storage tank 9 and conveying them to the spray pipe 13.

Material is conveyed from the feed pump 10 to the spray pipes 13. Both spray pipes 13 are fixedly connected to the discharge pipe 12, located above and below the woven fabric respectively, and are used to uniformly spray the coating material onto one or both sides of the woven fabric. Multiple spray heads 14 are respectively set on the two spray pipes 13, and are used to spray the coating material onto the woven fabric in a mist or fine stream. Through the two spray pipes 13 located above and below the woven fabric respectively, and the multiple spray heads 14, uniform spraying of one or both sides of the woven fabric is achieved, improving coating efficiency and quality.

[0026] In a further preferred embodiment of this utility model, a fan 15 is fixedly installed on one side of the dustproof box 2. The air outlet of the fan 15 is fixedly connected to an insulation shell 16. A heating element 17 is fixedly installed inside the insulation shell 16. An air outlet pipe 18 is fixedly connected to the air outlet of the insulation shell 16. The air outlet pipe 18 extends into the dustproof box 2 and is provided with multiple fabric air pipes 19. The multiple fabric air pipes 19 are respectively located at the conveying end and the winding end of the woven fabric for preheating the woven fabric and curing the coating.

[0027] In this embodiment, the fan 15 is fixedly installed on one side of the dustproof housing 2 to provide airflow and deliver heated air into the dustproof housing 2. The insulation shell 16 is fixedly installed at the air outlet of the fan 15 to wrap and insulate the heating element 17, ensuring heating efficiency. The heating element 17 heats the air, providing the heat required for coating curing. The air outlet duct 18 is fixedly connected to the air outlet of the insulation shell 16 to deliver heated air into the dustproof housing 2. Multiple fabric air ducts 19 are respectively located at the conveying end and the winding end of the woven fabric and are fixedly connected to the air outlet duct 18. The heating element 17 heats the air, which is used to evenly distribute heated air onto the woven fabric to achieve preheating and coating curing. The fan 15 provides airflow, and the heating element 17 heats the air. After being insulated by the insulation shell 16, the heated air is evenly distributed onto the woven fabric through the air outlet 18 and the air distribution duct 19 to achieve preheating and coating curing of the woven fabric. Preheating can increase the surface temperature of the woven fabric, so that the coating material can better adhere to the woven fabric during coating, thereby improving the adhesion of the coating. Curing helps to remove solvents or moisture from the coating, making the coating more robust.

[0028] In a further preferred embodiment of the present invention, a stirring wheel 20 is rotatably installed inside the storage box 9, and a stirring motor 21 is fixedly installed on one side of the storage box 9, with the output shaft of the stirring motor 21 fixed to the stirring wheel 20.

[0029] In this embodiment, the stirring wheel 20 is rotatably installed inside the storage tank 9 to stir the coating material and prevent it from settling or clumping. The stirring motor 21 is fixedly installed on one side of the storage tank 9, and its output shaft is fixed to the stirring wheel 20 to drive the stirring wheel 20 to rotate. By driving the stirring wheel 20 to rotate inside the storage tank 9, the stirring motor 21 can effectively stir the coating material and prevent it from settling or clumping due to prolonged stillness, thus ensuring the uniformity and stability of the coating material. The uniform coating material can ensure the uniformity and consistency of the coating process, thereby improving the coating quality.

[0030] In a further preferred embodiment of the present invention, a metering valve 22 and a switching valve 23 are fixedly installed on the discharge pipe 12, and the switching valve 23 is located at the spraying pipe 13 below the woven fabric.

[0031] In this embodiment, a metering valve 22 is fixedly installed on the discharge pipe 12 to precisely control the flow rate of the coating material, ensuring that the amount of coating material sprayed each time is consistent. A switching valve 23 is located at the spraying pipe 13 below the woven fabric and is fixedly installed on the discharge pipe 12 (or more precisely, at the connection point where the discharge pipe 12 branches to the lower spraying pipe 13). It controls the supply of coating material to the lower spraying pipe 13, enabling selective spraying of single-sided or double-sided coatings. The metering valve 22 can precisely control the flow rate of the coating material, ensuring that the amount of coating material sprayed each time is consistent, thereby improving the uniformity and consistency of the coating. The switching valve 23 can control the supply of coating material to the lower spraying pipe 13. When only single-sided coating is needed, the switching valve 23 of the lower spraying pipe 13 can be closed to achieve selective spraying, improving the flexibility and applicability of the equipment.

[0032] In a further preferred embodiment of the present invention, a loading port is provided on one side of the dustproof box 2, and a transparent observation door 24 for observing the coating condition is hinged to the loading port.

[0033] In this embodiment, the loading and unloading port is located on one side of the dustproof box 2 for placing and taking out the woven fabric, as well as for necessary maintenance and repair. The transparent observation door 24 is hinged to the loading and unloading port and is made of transparent material. It is used to observe the coating condition without opening the dustproof box 2, ensuring the smooth progress of the coating process. This allows operators to clearly observe the coating process without opening the dustproof box 2, promptly identify and solve problems, and improve production efficiency and coating quality.

[0034] In a further preferred embodiment of the present invention, an observation port for observing the amount of paint is provided on one side of the storage box 9, and a transparent observation plate 25 is provided on the observation port.

[0035] In this embodiment, an observation port is located on one side of the storage tank 9 for observing the remaining amount of coating material in the storage tank 9. A transparent observation plate 25 is installed on the observation port and is made of transparent material, so that the operator can clearly see the remaining amount of coating material in the storage tank 9. The design of the transparent observation plate 25 allows the operator to intuitively see the remaining amount of coating material in the storage tank 9, thereby replenishing the coating material in time and avoiding production interruption due to insufficient coating material during the coating process.

[0036] In summary, compared with related technologies, this device achieves highly efficient automation of the woven fabric coating process, significantly improves coating quality, and enhances operational convenience. It can perform single-sided or double-sided coating on woven fabrics as needed, and the coating mode (single-sided or double-sided coating) can be adjusted according to requirements, improving production flexibility and adaptability. By integrating multiple functions such as dust prevention, material storage, mixing, spraying, and observation, it significantly improves the automation level and coating quality of the woven fabric coating process, effectively isolates external impurities, ensures a clean coating environment, guarantees uniform supply of coating materials, and achieves uniformity and consistency of the coating through precise spraying control.
