Description

Technical Field

[0001] This invention relates to the field of rust inhibitor effectiveness testing technology, specifically to a rust inhibitor rust prevention effectiveness testing organization. Background Technology

[0002] Rust inhibitors are chemicals used to prevent metal products from oxidizing and rusting during production, storage, and transportation. They work by forming a protective film on the metal surface, preventing oxygen and moisture in the air from directly contacting the metal, thus preventing rust. The rust-preventing effect of the workpiece is tested using a testing device, which effectively assesses the overall rust-preventing performance of the workpiece.

[0003] However, existing testing institutions have complex operations and incomplete testing scope, which is time-consuming and labor-intensive, thus reducing testing efficiency and quality.

[0004] To address the aforementioned deficiencies, Chinese Patent Publication No. CN214539160U discloses a device for testing the anti-corrosion and anti-rust effect of rust inhibitors. This device includes a testing chamber and a base fixedly connected to the bottom of the chamber. The base protects the motor for normal operation. The test piece, sprayed with rust inhibitor, is placed on top of a turntable by opening the chamber cover. Rotating the rotating rod drives the threaded rod to rotate, causing a fixing block to move smoothly towards the test piece, thus securing it. Closing the chamber cover creates a sealed environment. Turning on the motor causes the output shaft to slowly rotate the turntable. A water pump delivers water from the tank cavity to a spray nozzle inside the testing chamber via a water outlet pipe. The spray nozzle evenly sprays water onto the surface of the test piece, simulating a humid environment. An oxygen generator is activated, and its outlet delivers oxygen to an exhaust port via a conduit pipe. The exhaust port then releases the oxygen into the testing chamber, simulating an oxygen-rich environment.

[0005] Furthermore, in the prior art, Chinese patent CN220039975U discloses a device for testing the anti-corrosion and anti-rust effect of rust inhibitors. This device includes a testing box, a fixing mechanism inside the testing box for fixing the workpiece to be tested, and a testing component located at the top of the testing box for testing the workpiece. The testing component includes a connecting block horizontally positioned inside the testing box and located at the top of the testing box, multiple nozzles evenly spaced on the bottom end face of the connecting block and communicating with the interior of the connecting block, and a liquid storage tank and a gas storage tank located at the top of the testing box and communicating with the interior of the connecting block. The fixing mechanism includes a positioning strip horizontally positioned inside the testing box, a fixing component on the positioning strip for fixing one side of the workpiece to be tested, and a control motor located on the side of the testing box and vertically connected to the center of the side of the positioning strip via a control rod passing through the testing box. This device can conveniently test the anti-corrosion and anti-rust effect of rust inhibitors and improves the accuracy of rust inhibitor testing.

[0006] The aforementioned device uses multiple components to simulate a humid and oxygen-rich environment during use. However, the device can only perform spray coating inspection on a single workpiece, and the anti-rust solution tends to accumulate inside the equipment after inspection, affecting subsequent inspections. Furthermore, it is difficult to ensure the uniformity and stability of environmental parameters during the inspection process, resulting in significant fluctuations in the inspection results. Summary of the Invention

[0007] The purpose of this invention is to provide a rust inhibitor rust prevention effect testing mechanism to solve the problem mentioned in the background art that the rust prevention effect can only be tested on a single workpiece.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figures 1-3 The present invention provides the following technical solution: a rust inhibitor rust prevention effect testing mechanism, comprising an upper frame 1, a lower frame 2 fixedly installed on the bottom surface of the upper frame 1, a support rod 3 fixedly installed on the inner side of the upper frame 1, a height adjustment component 4 fixedly installed on the inner side of the support rod 3, a magnetic adsorption component 5 fixedly installed on the bottom surface of the height adjustment component 4, and a multi-station spraying mechanism for auxiliary processing arranged below the magnetic adsorption component 5; a testing component 25 fixedly installed on the top of the lower frame 2, a storage box 26 fixedly installed on the top of the testing component 25, the storage box 26 being used to store rust inhibitor samples to be tested, and the testing component 25 being connected to a data acquisition and analysis system, capable of recording and analyzing the rust prevention effect data of the rust inhibitor in a simulated environment in real time.

[0023] The multi-station spraying mechanism enables simultaneous rust inhibitor spraying on multiple workpieces, significantly improving inspection efficiency. The bidirectional spray heads 21 within the mechanism are arranged in a rectangular array, ensuring uniform rust inhibitor coverage of the workpiece surface and enhancing inspection accuracy. Furthermore, the mechanism's design incorporates rust inhibitor recycling and reuse. Excess rust inhibitor can be easily collected and discharged via the collection trough 23 and drain outlet 24 at the bottom of the placement plate 22, reducing waste and environmental pollution. Additionally, the combined use of the height adjustment component 4 (including an electric push pump and electric push rod) and the magnetic adsorption component 5 (including an electromagnet and adsorption plate) allows for precise workpiece positioning. The spraying process remains stable, further improving the uniformity and quality of the spraying. The magnetic adsorption component 5 generates a strong magnetic force through an electromagnet, which firmly adsorbs the workpiece onto the adsorption plate. Even under high-intensity spraying operations, the workpiece will not shift or fall off, ensuring smooth inspection. This allows the spraying mechanism to be flexibly adjusted according to the size and shape of different workpieces. First, before spraying, the worker places the workpiece in the position of the magnetic adsorption component 5, which then adsorbs the workpiece. Subsequently, the position of the workpiece is adjusted under the drive of the height adjustment component 4. Once the workpiece reaches the fixed position, the surface of the workpiece is sprayed through the installed bidirectional spraying head 21.

[0024] Example 2: Based on Example 1, the problem of uneven coating in existing testing institutions is solved. Please refer to [link / reference]. Figures 2-6 The paper also discloses a bidirectional spray head 21, the specific structure of which is as follows: The multi-station spraying mechanism includes a spray box 20, which is located below the magnetic adsorption component 5. Multiple bidirectional spray heads 21 are fixedly installed on the inner side of the spray box 20. The multiple bidirectional spray heads 21 are arranged in a rectangular array, which can uniformly spray the rust inhibitor onto the surface of the workpiece to be inspected. A placement plate 22 is fixedly installed on the bottom surface of the spray box 20. The placement plate 22 adopts a double-layer separation design. The top layer of the placement plate 22 is used to place the workpiece. The bottom layer of the placement plate 22 is provided with a collection groove 23. A drain outlet 24 is opened on the side end of the bottom layer of the placement plate 22. Multiple sets of connecting blocks 6 are fixedly installed on both sides of the magnetic adsorption component 5. A drive rod 7 is provided at the outer connection of the two sets of connecting blocks 6. A linkage mechanism is provided at the connection end of the drive rod 7. The linkage mechanism includes a gear 1 8. A drive rod 7 is provided at the connection end of the gear 1 8. A gear 2 9 is meshed with the outer surface of the gear 1 8. A connecting rod 14 is provided at the shaft of the gear 1 8.

[0025] The bidirectional spray head 21 allows the rust inhibitor to be sprayed simultaneously from two directions, improving spraying efficiency and ensuring uniform coverage of the workpiece surface, avoiding spraying dead zones and thus improving the accuracy of rust prevention effect detection. The linkage mechanism, through the meshing connection of gear 8 and gear 9, realizes the synchronous movement of the drive rod 7, which in turn drives the stable movement of the magnetic adsorption component 5. This allows the spraying mechanism to be flexibly adjusted according to the size and shape of different workpieces, enhancing the applicability and flexibility of the detection mechanism. In addition, the cooperation of the connecting block 6 and the limiting rod 12 restricts the movement trajectory of the connecting block 6, ensuring the stable movement of the spraying mechanism in the vertical direction, further improving the stability and reliability of the detection mechanism. After spraying, the workpiece is removed and placed on the placement plate 22. At this time, the bidirectional spray head 21 sprays the other side of the workpiece. Meanwhile, the sprayed rust inhibitor flows into the collection tank 23 and is then discharged from the drain outlet 24, facilitating recycling and saving resources.

[0026] Example 3: Based on Example 1, this example solves the problem of existing testing institutions only performing a single test. Please refer to [link / reference]. Figures 3-10 The paper also discloses a spray painting box 20, the specific structure of which is as follows: a crankshaft 10 is provided at the outer connection of another set of connecting blocks 6, a positioning rod 11 is connected to the inner side of the crankshaft 10, the positioning rod 11 is movably installed on the inner side of the upper frame 1, a limit rod 12 is movably installed on the inner side of the connecting block 6, the connecting block 6 moves vertically along the limit rod 12, the upper frame 1 is fixedly installed at the top of the limit rod 12, the lower frame 2 is fixedly installed on the bottom surface of the limit rod 12, a fixing frame 13 is fixedly installed on the inner side of the lower frame 2, and a fixing frame 13 is fixedly installed on the outer surface of the fixing frame 13. The lower frame 2 is equipped with a placement plate 22. A spray box 20 is fixedly installed on the inner side of the lower frame 2. A fixing rod 15 is fixedly installed on the inner side of the upper frame 1. A detection and sealing mechanism is provided on the inner side of the fixing rod 15. The detection and sealing mechanism includes a telescopic component 16. The telescopic component 16 is fixedly installed on the inner side of the fixing rod 15. A sealing component 17 is provided at the connecting end of the telescopic component 16. Mounting blocks 18 are fixedly installed on both sides of the sealing component 17. A linkage rod 19 is provided at the outer connecting end of the mounting block 18. The linkage rod 19 is movably installed on the outer side of the upper frame 1.

[0027] The clever design of crankshaft 10 and positioning rod 11 ensures that connecting block 6 maintains a stable trajectory during movement, further enhancing the motion accuracy of the spraying mechanism. Simultaneously, the limiting rod 12 not only restricts the movement range of connecting block 6 but also ensures its stable movement in the vertical direction, preventing uneven spraying caused by shaking. The introduction of the detection sealing mechanism, through the cooperation of telescopic component 16 and sealing component 17, enables rapid sealing and opening of the detection environment, providing a more stable and reliable environmental condition for rust prevention effect detection. The design of linkage rod 19 makes the movement of the entire mechanism more coordinated and smooth, improving detection efficiency. The sprayed workpiece is dried in an oven. After drying, the workpiece is placed in storage box 26. Subsequently, water is injected into storage box 26, and the telescopic component 16 (including a hydraulic pump and telescopic rod) drives the sealing component 17 (including a sealing cover and a sealing rod installed on the sealing cover). The sealing strips around the plate move, and the sealing assembly 17 seals the storage box 26. The detection assembly 25 (including a humidity sensor, a temperature sensor, and a corrosion rate monitor) monitors the environmental parameters inside the storage box 26 in real time, and records the rust-preventing effect data of the rust inhibitor under different humidity and temperature conditions through a data acquisition and analysis system. This system can accurately capture key indicators of the rust inhibitor's performance changes, such as the reduction in corrosion rate and the proportion of surface rust area, providing a quantitative basis for evaluating the comprehensive performance of the rust inhibitor. In addition, the detection sealing mechanism realizes the rapid opening and closing of the sealing cover through hydraulic drive, and the synchronous movement mechanism of the linkage rod 19 ensures the sealing of the detection environment and effectively avoids the interference of external factors on the experimental results. Through multi-parameter collaborative monitoring and automated control, this detection mechanism significantly improves the objectivity and repeatability of the rust prevention effect evaluation, thereby achieving efficient detection of the rust prevention effect of the workpiece.
