A stainless steel wire uniform coating device

Abstract

This utility model discloses a uniform coating device for stainless steel wire, including a worktable, a processing cover on the worktable, a spraying component on the processing cover, and drying components symmetrically arranged at both ends of the spraying component inside the processing cover. Through holes are opened at both ends of the processing cover. A cleaning component is installed at one end of the worktable via a drive mechanism, and a drying component is also installed on the worktable, located between the cleaning component and the processing cover. This utility model uses a drive mechanism to rotate the threaded wiping pad of the cleaning component, which can dynamically clean the surface of the stainless steel wire, effectively removing adhering dust, trace oxide layers, and adsorbed moisture after winding and storage. This avoids impurities affecting the uniformity of coating adhesion and reduces the risk of moisture forming a "moisture interlayer" during the curing process, thus reducing coating bubbles or local bulging defects from the source.

Description

Technical Field

[0001] This utility model relates to the field of stainless steel wire processing technology, specifically to a device for uniformly coating stainless steel wire. Background Technology

[0002] Stainless steel wire is a type of wire made from metals such as iron, chromium, and nickel as its base alloys. It possesses excellent corrosion resistance, high-temperature stability, and mechanical strength, and is widely used in aerospace, petrochemical, and medical device manufacturing industries—situations with stringent material performance requirements. However, under complex service environments (such as high humidity, acidic or alkaline media, or frequent friction conditions), the surface properties of stainless steel wire may still degrade due to oxidation, mechanical wear, or media erosion. Specifically, this manifests as decreased corrosion resistance, reduced wear resistance, and weakened functional properties. To address these issues, coating technology has become a key technological approach. By uniformly coating functional materials (such as polymer coatings, ceramic coatings, or metal plating), the corrosion resistance, wear resistance, and electrical insulation properties of stainless steel wire can be significantly improved, while also imparting functional properties such as fingerprint resistance and self-lubrication. Coating equipment, as the core device for achieving uniform coating, directly affects the final coating quality and the service life of stainless steel wire products, making it a crucial technological equipment in the field of stainless steel wire deep processing.

[0003] However, in actual production, stainless steel wire usually needs to be wound and stored before coating. After long-term storage, its surface is prone to adhering to dust and forming a trace oxide layer, and may also absorb moisture from the environment. If coating is applied directly without pretreatment, the dust will cause uneven local adhesion of the coating, the oxide layer will reduce the bonding strength between the coating and the substrate, and the moisture will form a "moisture interlayer" during the coating curing process, resulting in bubbles or local bulging defects after curing, which seriously affects the coating processing quality and product performance. Utility Model Content

[0004] The purpose of this invention is to provide a device for uniformly coating stainless steel wire to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a uniform coating device for stainless steel wire, comprising a worktable, a processing cover on the worktable, a spraying component on the processing cover, drying components symmetrically arranged at both ends of the spraying component inside the processing cover, through holes at both ends of the processing cover, a cleaning component arranged at one end of the worktable via a drive mechanism, and an air-drying component also arranged on the worktable, the air-drying component being located between the cleaning component and the processing cover.

[0006] Preferably, in order to facilitate the spraying of stainless steel wire and ensure sufficient and uniform coating, the spraying assembly includes a storage box set on the processing cover, a discharge pipe set on the side wall of the storage box, the discharge pipe passing through the processing cover and extending into the interior where an annular spray pipe is set, and spraying heads are equidistantly arranged on the annular spray pipe, with the center of the annular spray pipe and the center of the through hole on the same axis.

[0007] Preferably, in order to allow for drying before spraying and curing after spraying, the drying assembly includes heating rings equidistantly arranged inside the processing hood, with the top of the heating rings fixedly connected to the processing hood via a fixing rod.

[0008] Preferably, in order to facilitate the rotation of the cleaning component and ensure the cleaning effect on the surface of the stainless steel wire, the drive mechanism includes a mounting base set on the workbench, a motor set on the mounting base, a main gear fixedly set at the output end of the motor, a driven gear meshing on one side of the main gear, and the driven gear connected to the cleaning component.

[0009] Preferably, in order to facilitate cleaning of the stainless steel wire surface and ensure cleanliness before spraying, the cleaning component includes a hollow tube fixedly connected to the gear, and a threaded wiping pad is provided inside the end of the hollow tube away from the processing cover.

[0010] Preferably, in order not to affect the rotation and cleaning of the hollow tube with the threaded wiping pad, and not to affect the conveying of the stainless steel wire, a rotating bearing is installed on the outside of the hollow tube, and the bottom of the outer ring of the rotating bearing is fixedly connected to the worktable through a column.

[0011] Preferably, in order to air dry the cleaned surface and assist in cleaning impurities, the air drying assembly includes a blower device set on the processing table, an air outlet pipe provided at the conveying end of the blower device, and an air outlet opening at an equal distance at one end of the air outlet pipe near the hollow tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) The threaded wiping pad of the cleaning component is rotated by the drive mechanism, which can dynamically clean the surface of the stainless steel wire, effectively remove the floating dust, trace oxide layer and adsorbed water vapor attached after winding and storage, avoid impurities affecting the uniformity of coating adhesion, and reduce the risk of water vapor forming "water vapor interlayer" during the curing process, thereby reducing coating bubbles or local bulging defects from the source. (2) The air drying component uses an inclined air outlet design to blow and air dry the surface of the stainless steel wire after cleaning, further removing residual moisture and assisting in cleaning impurities, ensuring that the surface is clean and dry before entering the spraying process, and improving the bonding strength between the coating and the substrate. The drying components symmetrically arranged inside the processing hood pre-dry the coating before spraying and cure it after spraying through the heating ring, ensuring that the coating is thoroughly dried and the curing effect is stable, improving the coating's corrosion resistance, wear resistance and functional characteristics.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4This utility model provides an embodiment of a stainless steel wire uniform coating device, including a workbench 11, a processing cover 12 on the workbench 11, and through holes 15 at both ends of the processing cover 12 to facilitate the passage of stainless steel wire without affecting subsequent drying, spraying, and curing operations. After processing, the processing cover 12 is removed for subsequent processing operations. A spraying assembly is provided on the processing cover 12, including a storage box 13 on the processing cover 12, a discharge pipe 14 on the side wall of the storage box 13, the discharge pipe 14 penetrating the processing cover 12 and extending into the interior where an annular spray pipe 16 is provided, and spraying heads 17 are equidistantly arranged on the annular spray pipe 16. The centers of the nozzle 16 and the through hole 15 are on the same axis. A gear metering pump is used to ensure that the material supply per unit time matches the wire linear speed, ensuring that the spraying is sufficient and uniform. This is a relatively mature technology and will not be elaborated here. In order to ensure drying before spraying and curing after spraying, drying components are symmetrically arranged at both ends of the spraying component inside the processing cover 12. The drying components include heating rings 42 that are equidistantly arranged inside the processing cover 12. The top of the heating rings 42 is fixedly connected to the processing cover 12 by a fixing rod 41. The heating rings 42 can be heated by electric heating or other methods, whichever is convenient for drying and subsequent curing operations.

[0017] Please see Figures 1-4To allow for further treatment of the stainless steel wire surface before spraying, preventing oxide layers and moisture from affecting the uniformity and quality of the spraying, a cleaning component is installed at one end of the worktable 11 via a drive mechanism. A drying component is also installed on the worktable 11, located between the cleaning component and the processing cover 12. The drive mechanism includes a mounting base 21 on the worktable 11, on which a motor 22 is mounted. A main gear 23 is fixedly mounted at the output end of the motor 22, and a driven gear 25 meshes with one side of the main gear 23. The driven gear 25 is connected to the cleaning component. The cleaning component includes a hollow tube 27 fixedly connected to the driven gear 25. A threaded wiping pad 28 is installed inside the end of the hollow tube 27 furthest from the processing cover 12. The threaded wiping pad 28 can be made of a flexible material such as rubber, ensuring effective cleaning while preventing scratches on the stainless steel wire surface. A rotating bearing 26 is rotatably mounted on the outside of the hollow tube 27. The hollow tube 27 is fixedly connected to the inner ring of the rotating bearing 26. The bottom of the outer ring of the rotating bearing 26 is fixedly connected to the worktable 11 via a column 24. The main gear 23 is rotated by the motor 22, which in turn rotates the driven gear 25 and the hollow shaft on the rotating bearing 26, and rotates the threaded wiping pad 28, thereby cleaning the circumferential surface of the stainless steel wire and ensuring the cleaning effect. The air drying assembly includes a blower 31 mounted on the processing table, which can be a blower or a hot air blower, to facilitate air drying after cleaning and to help blow the cleaned impurities out of the hollow tube 27. An air outlet 32 ​​is provided at the conveying end of the blower 31. An air outlet 33 is equidistantly and inclinedly opened at one end of the air outlet 32 ​​near the hollow tube 27, which can help blow the cleaned impurities out of the hollow tube 27 and prevent them from remaining inside the hollow tube 27.

[0018] Working Principle: In use, this invention conveys the stainless steel wire to be coated through the hollow tube 27. Simultaneously, the motor 22 operates, driving the main gear 23 to rotate. The driven gear 25 and the hollow tube 27 rotate on the rotating bearing 26, which in turn rotates the internal threaded wiping pad 28. The stainless steel wire passes through the hollow tube 27, and the threaded wiping pad 28 cleans the surface. Simultaneously, the blower 31 operates, introducing air into the air outlet 32 ​​and blowing it out through the air outlet 33, which cleans and dries the surface of the stainless steel wire. The auxiliary material blows out impurities inside the hollow tube 27 to prevent accumulation. The cleaned and dried stainless steel wire enters the processing cover 12 through the through hole 15, and then passes through the heating ring 42 for heating and drying to prevent residual moisture on the surface and ensure that drying does not affect subsequent spraying. After drying, the spraying material in the storage box 13 is transported to the annular spray pipe 16 through the discharge pipe 14 and sprayed through the spray head 17. Then it passes through the heating ring 42 at the rear end for heating and curing to complete the processing. Finally, it is removed through the through hole 15 at the rear end for convenient subsequent processing operations.

[0019] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
