Description

Technical Field

[0001] This utility model mainly relates to the technical field of vapor phase rust inhibitor paper production, specifically a coating device for vapor phase rust inhibitor paper production. Background Technology

[0002] Vapor phase corrosion inhibitor paper is a special packaging material that prevents metal products from rusting by forming a protective atmosphere in a closed space using volatile corrosion inhibitors. The coating is applied to the surface of the paper using a vapor phase corrosion inhibitor paper coating device, and a long-lasting anti-rust layer is formed by drying and curing. The porous material adsorbs the corrosion inhibitor, achieving a slow-release effect. It is widely used in the transportation, storage and long-term sealing of metal products. However, existing coating devices lack the structure of combing the surface of the vapor phase corrosion inhibitor paper before coating, resulting in low coating quality.

[0003] According to application number CN202420570369.5, a vapor phase rust inhibitor coating device includes a transfer box, two coating mechanisms, a placement mechanism, a connecting mechanism, multiple transmission rollers, multiple auxiliary rollers, and two adapter interfaces. The two adapter interfaces are located on both sides of the transfer box, and the two coating mechanisms are installed opposite each other inside the transfer box. Each coating mechanism includes a housing, a snap-fit ​​assembly, a moving assembly, and a pressing assembly. The snap-fit ​​assembly is installed on the housing, the moving assembly is installed inside the housing, and the pressing assembly is located at the bottom of the housing. The moving assembly is connected to the placement mechanism.

[0004] The aforementioned document, through improvements to the coating head design, enables double-sided coating of vapor phase rust inhibitor paper, which will greatly improve production efficiency and reduce the number of coating operations and operational complexity. However, it lacks a uniform treatment of the vapor phase rust inhibitor paper surface before coating, resulting in low coating quality. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a coating device for producing vapor phase rust-preventive paper, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A coating device for producing vapor phase rust-inhibiting paper includes a mounting rail, a support frame fixedly mounted on the top of the mounting rail, feeding and discharging components rotatably mounted at both ends inside the mounting rail, two heating wheels rotatably mounted in the center inside the mounting rail, a limiting rod rotatably mounted inside the mounting rail at each end of the two heating wheels that are far apart from each other, cleaning components at the upper and lower ends of the two heating wheels, a transmission component on one side of the outer side of the mounting rail, and a spraying component on the discharge side of the mounting rail, with a scraper fixedly mounted at the discharge end of the spraying component.

[0008] Preferably, the feeding and discharging components include two feeding rollers that are rotatably mounted inside one end of the mounting guide rail, and two discharging rollers that are rotatably mounted inside the other end of the mounting guide rail. A first gear is fixedly mounted on one end of the discharging rollers, and the two first gears mesh with each other. A first motor is mounted on one side of the mounting guide rail, and the actuator end of the first motor is connected to the central shaft of the discharging rollers.

[0009] Preferably, one heating wheel heats the top surface of the vapor phase rust-preventing paper, and another heating wheel heats the bottom surface of the vapor phase rust-preventing paper. The two heating wheels are close to each other, and the vapor phase rust-preventing paper passes through the surfaces of the two heating wheels in an S-shape.

[0010] Preferably, each of the two limiting rods is close to the surface of one of the heating wheels, and vapor phase rust-preventive paper passes through the middle of the limiting rod and the heating wheel. Two limiting posts are bolted to both ends of the side wall of the limiting rod.

[0011] Preferably, the cleaning component includes a first cleaning roller disposed on the top of one of the heating wheels and rotatably mounted inside the mounting guide rail, and a second cleaning roller disposed on the bottom of the other heating wheel and rotatably mounted inside the mounting guide rail. Multiple sets of bristle brushes are fixedly mounted on the sidewalls of the first cleaning roller and the second cleaning roller.

[0012] Preferably, the transmission component includes a wide gear fixedly connected to one end of the heating wheel, two wide gears meshing with each other, a second gear fixedly installed at the same end of the limiting rod, the second gear meshing with one of the wide gears, a third gear fixedly installed at the same end of the first cleaning roller and the second cleaning roller, the third gear meshing with one of the wide gears, and a second motor installed on the other side of the mounting guide rail, the actuating end of the second motor being connected to the central shaft of one of the heating wheels.

[0014] In summary, this technical solution has the following main advantages:

[0015] This invention significantly improves coating uniformity and production efficiency through an innovative double-sided heating and limiting system. The device adopts an S-shaped path design, which allows both sides of the paper to contact the heating rollers in sequence, simultaneously eliminating internal stress and enhancing coating adhesion. The limiting rod combined with the adjustable limiting column forms an adaptive limiting structure, which precisely constrains the lateral deviation of the paper and ensures that the heating area is centered. The transmission system realizes the linkage between the heating roller and the cleaning roller through gear meshing, ensuring that all components operate synchronously.

[0016] The device optimizes the entire process through high-speed cleaning and intelligent spraying. The cleaning roller drives the bristle brush at a higher speed than the heating roller to continuously remove surface impurities and smooth paper wrinkles. The double-sided spraying system combines atomized spraying technology with a precision scraper to control the coating thickness and form a uniform anti-rust film. The closed-loop transmission design enables the feed rollers, heating roller and cleaning components to work together, improving coating quality while achieving continuous production and meeting the high-standard manufacturing requirements of industrial-grade anti-rust paper.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Example

[0025] Please refer to the attached document carefully. Figure 1 , 2 As shown in Figures 3 and 4, a coating device for producing vapor phase rust-inhibiting paper includes a mounting guide rail 10, a support frame 11 fixedly mounted on the top of the mounting guide rail 10, feeding and discharging components 12 rotatably mounted at both ends inside the guide rail 10, two heating wheels 13 rotatably mounted in the center inside the guide rail 10, each of the two heating wheels 13 having a limiting rod 14 rotatably mounted inside the mounting guide rail 10 at its far-away ends, cleaning components 15 at the upper and lower ends of the two heating wheels 13, a transmission component 16 on one side of the outside of the mounting guide rail 10, and a spraying component 17 on the discharge side of the mounting guide rail 10, with a scraper 18 fixedly mounted at the discharge end of the spraying component 17; the feeding and discharging components 12 include two feeding rollers 12 rotatably mounted at one end inside the mounting guide rail 10. 1. Two discharge rollers 122 are mounted inside the guide rail 10 and rotate up and down at the other end. A first gear 123 is fixedly mounted on one end of the discharge roller 122. The two first gears 123 mesh with each other. A first motor 124 is mounted on one side of the guide rail 10. The actuator end of the first motor 124 is connected to the central shaft of one discharge roller 122. One heating wheel 13 heats the top surface of the vapor phase rust-preventing paper, and another heating wheel 13 heats the bottom surface of the vapor phase rust-preventing paper. The two heating wheels 13 are close to each other, and the vapor phase rust-preventing paper passes through the surface of the two heating wheels 13 in an S-shape. Two limiting rods 14 are each close to the surface of one heating wheel 13. The vapor phase rust-preventing paper passes through the middle of the limiting rod 14 and the heating wheel 13. Two limiting posts 141 are bolted to both ends of the side wall of the limiting rod 14.

[0026] As described above, during the operation of the coating device for producing vapor phase rust-inhibiting paper, the mounting guide rail 10 serves as the core support structure, and the support frame 11 fixes the spraying component 17 and the storage tank 173. The vapor phase rust-inhibiting paper is first introduced by the upper and lower feed rollers 121 of the feeding and discharging component 12. The first motor 124 drives the discharge roller 122 to rotate, and the two first gears 123 mesh to realize the synchronous reverse rotation of the upper and lower discharge rollers 122, ensuring that the paper passes through at a constant tension and uniform speed, avoiding wrinkles or stretching deformation. After the paper enters the center of the mounting guide rail 10, it winds around the two gears in an S-shape. On the surface of the heating wheel 13, the heating wheel 13 is driven by the second motor 164 of the transmission component 16. The two wide gears 161 mesh to make the two wheels rotate in opposite directions, heating the top and bottom surfaces of the paper at 150℃±2℃ respectively, eliminating internal stress in the material and enhancing the adhesion of the coating. The limiting rod 14 rotates synchronously through the meshing of the second gear 162 and the wide gear 161, pressing the two ends of the vapor phase rust-preventing paper tightly against the side wall of the heating wheel 13. The spacing of the limiting posts 141 bolted to both ends of the side wall is adjustable, constraining the lateral displacement of the paper and ensuring that the heating area is centered and the edges are aligned.

[0027] Please refer to the attached document carefully. Figure 1 , 3As shown in Figure 5, the cleaning component 15 includes a first cleaning roller 151 disposed on the top of a heating wheel 13 and rotatably mounted inside the mounting guide rail 10, and a second cleaning roller 152 disposed on the bottom of another heating wheel 13 and rotatably mounted inside the mounting guide rail 10. Multiple sets of bristle brushes 153 are fixedly mounted on the side walls of the first cleaning roller 151 and the second cleaning roller 152. The transmission component 16 includes a wide gear 161 fixedly connected to one end of the heating wheel 13, with two wide gears 161 meshing with each other. A second gear 162 is fixedly mounted on the same end of the limiting rod 14, and the second gear 162 meshes with one wide gear 161. The first cleaning roller 151 and... A third gear 163 is fixedly installed at the same end of the second cleaning roller 152. The third gear 163 meshes with a wide gear 161. A second motor 164 is installed on the other side of the mounting guide rail 10. The execution end of the second motor 164 is connected to the central shaft of a heating wheel 13. The spraying component 17 includes two spraying pipes 171 fixedly installed on the discharge side of the mounting guide rail 10. A row of spray nozzles 172 is provided on the side of the spraying pipes 171 facing the vapor phase anti-rust paper. A liquid storage tank 173 is fixedly installed on the top of the support frame 11. A liquid pump 174 is connected to a flange on one side of the liquid storage tank 173. The output end of the liquid pump 174 is connected to the spraying pipes 171 through a liquid guide pipe 175.

[0028] As described above, the first cleaning roller 151 and the second cleaning roller 152 of the cleaning component 15 are meshed and linked with the wide gear 161 through the third gear 163. The number of teeth of the wide gear 161 is much greater than the number of teeth of the third gear 163, so that the first cleaning roller 151 and the second cleaning roller 152 rotate at a speed much greater than that of the heating wheel 13. This drives multiple sets of bristle brushes 153 to continuously clean the materials or dust on the vapor phase rust-preventive paper attached to the surface of the heating wheel 13. At the same time, the surface of the vapor phase rust-preventive paper is combed, which helps the heating wheel 13 to remove wrinkles and makes it easier to apply the rust-preventive liquid evenly. After combing and heating, the paper is moved to the spraying component 17. The liquid pump 174 draws the rust-preventive liquid from the storage tank 173 and delivers it to the upper and lower spraying pipes 171 through the liquid guide pipe 175. The spray head 172 sprays the paper under pressure to form a uniform liquid film. The gap between the scraper plate 18 and the paper is small, scraping off the excess coating and compacting the coating to ensure uniform thickness.

[0029] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
