[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1-4 As shown in the figure, this utility model embodiment proposes a vapor phase rust inhibitor coating device, comprising:

[0022] The liquid supply tank 1, coating tank 2, and drying chamber 3 are arranged adjacently and installed together. The liquid supply tank 1 has a top cover, which allows for cleaning of the interior. Similarly, the coating tank 2 and drying chamber 3 are each equipped with a cover, which allows for maintenance and other procedures on their interiors. The coating tank 2 and drying chamber 3 have unwinding and rewinding rollers on their sides, respectively, which are not shown in the figure.

[0023] The two conveying grooves are provided through the coating box 2, one of which is communicated with the drying box 3, so that the gas-phase rust-proof paper to be coated can be smoothly conveyed through the conveying grooves into the coating box 2 and the drying box 3, meeting the needs of continuous production. In order to further optimize the conveying path of the gas-phase rust-proof paper, the coating box 2 is specially provided with a guide roller 4. The guide roller 4 is arranged corresponding to the conveying groove, and the accurate position design ensures that the gas-phase rust-proof paper can always keep the correct direction during conveying.

[0024] In addition, the coating box 2 is also firmly provided with a bracket, and the guide roller 4 is stably installed on the bracket. Such a structure design not only enhances the stability of the guide roller 4, but also enables it to maintain good guiding effect in long-term use. The main function of the guide roller 4 is to guide the gas-phase rust-proof paper to be conveyed according to the predetermined path, avoiding the deviation or jamming of the paper during conveying, thereby improving the production efficiency and product quality.

[0025] The mixing and coating assembly comprises two pump bodies 5 installed on the liquid supply tank 1. The two pump bodies 5 are arranged to ensure that the pressure of the spray head 10 is the same, thereby ensuring the quality of the coating. The liquid inlet end of the pump body 5 is provided with a liquid inlet pipe 6 connected with the liquid supply tank 1, and the liquid outlet end of the pump body 5 is provided with a mixing pipe 7 penetrating through the liquid supply tank 1. The first electromagnetic valve 11 is installed on the mixing pipe 7 and located outside the liquid supply tank 1 for installation or maintenance. When the raw materials are mixed, the first electromagnetic valve 11 is opened.

[0026] When the coating liquid is mixed, the raw materials are added into the liquid supply tank 1, and then the pump body 5 is started. The pump body 5 works to convey the raw material liquid into the liquid supply tank 1 through the liquid inlet pipe 6 and the mixing pipe 7. Since the two pump bodies 5 work simultaneously, the raw materials are sucked in through the liquid inlet pipe 6 and discharged through the mixing pipe 7. Since the mixing pipe 7 is located on both sides of the liquid supply tank 1, the raw materials can circulate in the liquid supply tank 1, so that the raw materials can be mixed to form the coating liquid.

[0027] ​The pump body 5 is provided with a delivery pipe 8, and the second electromagnetic valve 12 is arranged on the delivery pipe 8 and outside the liquid supply tank 1; the first electromagnetic valve 11 and the second electromagnetic valve 12 are respectively controlled by a separate switch, so that the mixing and coating of the coating liquid can be more effectively controlled; the coating tank 2 is provided with coating pipes 9 connected with the delivery pipe 8, and the coating pipes 9 are provided with atomizing nozzles 10; the two coating pipes 9 are arranged in parallel and oppositely; the gas phase rust-proof paper is moved to the space between the two coating pipes 9 through the conveying groove; the first electromagnetic valve 11 is closed, the second electromagnetic valve 12 is opened, the pump body 5 works to deliver the coating liquid to the coating pipes 9 through the delivery pipe 8, and finally the coating liquid is sprayed out through the atomizing nozzles 10; the coating amount on the paper is generally 5-30g / m2, which can be adjusted according to the specific rust-proof requirement and the material of the metal product.

[0028] The coated gas phase rust-proof paper is moved to the drying tank 3, wherein the drying tank 3 is provided with a drying device, and the drying device is a hot air circulation drying device; the working principle is that the heated air is uniformly blown into the drying chamber through hot air circulation to dry the gas phase rust-proof paper; the drying device can also be other drying devices, which are not limited.

[0029] In summary, the pump body used for coating and the liquid supply tank combined with the pump body can not only efficiently mix the coating liquid without additional mixing equipment, but also reduce the transfer and waste of the coating liquid; the two pump bodies are arranged to ensure that the pressure of the atomizing nozzles is the same, thereby ensuring the coating quality.
