Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal product processing technology, and in particular to a metal product anti-rust spraying equipment. Background Technology
[0002] Metal products are increasingly used in various fields of industry, agriculture, and people's lives, such as metal product manufacturing, metal tool manufacturing, container and metal packaging container manufacturing, stainless steel and similar daily metal products manufacturing, etc. After the metal products are processed, they need to be coated with anti-rust coating to improve their durability.
[0003] In existing technologies, metal products need to be painted after processing. Traditionally, this is done by manually applying the paint and then letting it air dry, which cannot improve work efficiency and results in high labor intensity for operators.
[0004] An existing patent (publication number: CN214077479U) discloses a rust-proof spraying device for metal products. After the threaded rod rotates, it drives the threaded sleeve to move. After the threaded sleeve moves, the spray head moves to spray paint. After the paint is sprayed, the hot air blower works and sends hot air into the first chamber to dry the painted metal. The air is then discharged from the outlet through the filter mechanism.
[0005] To address the aforementioned issues, while existing patents offer solutions that can spray rust-preventive paint onto metal products and then dry them using components such as spray nozzles and hot air blowers, the continuous operation of these two processes results in a longer actual usage time, leading to slower processing efficiency and impacting production capacity. Summary of the Invention

[0010] Preferably, the spraying rod and the feeding tube form a rotating structure, and the feeding tube has an L-shaped structure.
[0011] Preferably, the nozzles are evenly distributed at equal intervals around the outer wall of the spraying rod, and the spraying rod passes through the worm gear and the mounting housing to form a rotating structure.
[0012] Preferably, a processing mechanism is provided on both sides of the outer wall of the baffle.

Detailed Implementation
[0025] 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.
[0026] This utility model provides a technical solution:
[0027] Please see Figures 1 to 3A metal product anti-rust spraying device includes a base 1, with baffles 2 fixed on both sides of the top of the base 1. A coating mechanism 3 is installed inside the base 1. The coating mechanism 3 includes a rotating frame 301, which is rotatably connected between the two baffles 2 at the top of the base 1. A first motor 302 is embedded inside the base 1, and a first electromagnet 303 is embedded in the axial inner wall of the rotating frame 301. A mounting shell 304 is fixedly installed on the top of the baffles 2. A feed pipe 306 is inserted through one side of the outer wall of the mounting shell 304, and a second motor 305 is embedded in the other side of the outer wall of the mounting shell 304. The power output end of the second motor 305 is connected to a worm gear 307. The worm gear 307 is inserted into the outer wall of the mounting housing 304 and is engaged with a worm wheel 308. A spraying rod 309 extends out of the worm wheel 308. A nozzle 310 is embedded at the end of the spraying rod 309 that is inserted into the worm wheel 308. The rotating frame 301 has a cross-shaped structure. The rotating frame 301 forms a rotating structure with the base 1 through the first motor 302. The spraying rod 309 forms a rotating structure with the feed pipe 306. The feed pipe 306 has an L-shaped structure. The nozzles 310 are evenly distributed at equal intervals around the outer wall of the spraying rod 309. The spraying rod 309 passes through the worm wheel 308 and forms a rotating structure with the mounting housing 304.
[0028] By adopting the above technical solution, the first electromagnet 303 firstly magnetically attracts the metal products to the axial end of the rotating frame 301 to prevent them from loosening. The first motor 302 then operates, causing the rotating frame 301 to rotate. This sequentially drives four sets of metal products through spraying, inspection, drying, and loading / unloading processes, improving processing efficiency through multi-stage processing. When the metal products enter the first baffle 2, the second motor 305, worm gear 307, and worm wheel 308 rotate, causing the spraying rod 309 to rotate under the engagement of the feed pipe 306. This allows the spray nozzle 310 to spray the metal products 360 degrees around them, improving the comprehensiveness of the spraying process. After spraying is completed, the first motor 302 operates to rotate the rotating frame 301, allowing the sprayed metal products to pass through the baffle 2 for easy inspection by staff to ensure complete spraying. The second set of metal products then enters the baffle 2 for spraying.
[0029] Specifically, such as Figure 1 and Figure 4As shown, processing mechanisms 4 are provided on both sides of the outer wall of the baffle 2. The processing mechanism 4 includes a drying equipment body 401, which is embedded in the top of another baffle 2. Sealing plates 402 are fixedly installed on both sides of the outer wall of the baffle 2. A second electromagnet 403 is embedded in the upper part of the sealing plate 402. The processing mechanism 4 also includes a sliding plate 404, which extends out of the bottom end of the sealing plate 402. A limit block 405 is fixed at one end of the sliding plate 404 that extends into the sealing plate 402. The sliding plate 404 and the sealing plate 402 form a sliding structure, and the sealing plate 402 and the limit block 405 form a sliding structure.
[0030] By adopting the above technical solution, after inspection, the first group of metal products enters the baffle 2 of the main body 401 of the mounting and drying equipment for drying through the cooperation of the first motor 302 and the rotating frame 301. The second group of metal products is inspected, and the third group of metal products is sprayed. The simultaneous operation improves processing efficiency. Both baffles 2 are fixed with sealing plates 402. The second electromagnet 403 magnetically attracts the permanent magnet material limiting block 405, thereby allowing the sliding plate 404 to slide, thereby closing and opening the baffle 2. The sealing provides a seal during spraying and drying, and the opening facilitates position adjustment.
[0031] Working principle: The base 1 fixes the baffle 2 in place. Metal products are magnetically attracted to the rotating frame 301 by the first electromagnet 303. The first motor 302, mounted in the mounting housing 304, drives the rotating frame 301 to carry the metal products for sequential feeding, painting, inspection, and drying, thereby improving processing efficiency. When the metal product enters the first baffle 2, the second motor 305 operates, driving the worm gear 307 and worm wheel 308, causing the spraying rod 309 to rotate under the engagement of the feeding pipe 306, supplying the metal product with the coating. The material pipe 306 is connected to an external feeding device, so that the paint is sprayed out through the nozzle 310. After spraying, it passes through the first baffle 2 under the drive of the rotating frame 301. After the staff checks whether the spraying is qualified, it then enters the second baffle 2 and is dried by the drying equipment body 401. Each baffle 2 is equipped with a sealing plate 402. The second electromagnet 403 magnetically attracts the permanent magnet material limit block 405, allowing the lightweight PVC material sliding plate 404 to slide, so as to seal during spraying and drying, and open when adjusting the position.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
