Description

Technical Field

[0001] This invention relates to testing equipment technology, specifically to a testing device and method for a new type of coating material. Background Technology

[0002] As a surface protective layer for tubular components (such as pipes, wire harness sleeves, and structural parts), the wear resistance and adhesion of coatings directly affect the service life and safety performance of the components, while the flowability affects the application performance and film quality of the coating. Therefore, comprehensive performance testing of coatings is of great significance.

[0003] Chinese invention patent CN120628912A discloses a coating viscosity testing device. This device uses a clamping assembly located at the lower part of the housing to clamp the connector, restricting its position and preventing it from swinging or rotating. The connector is then lifted by driving the clamping assembly upwards. Because the connector is clamped vertically, after the rotor is installed, the clamping assembly resets and releases the connector. The connector does not swing, allowing the housing to be lowered directly to move the rotor below the surface of the coating for testing, without waiting for the rotor to stabilize or manually supporting it.

[0004] Existing equipment is mostly used for flat specimens, while tubular components have curved structures and may be in various postures such as bending, twisting, and swaying during actual use. This makes it impossible to accurately perform multi-directional dynamic testing of the flowability of curved components under different adhesion states. At the same time, testing in a single direction may underestimate or overestimate the performance of the coating, thus failing to test the coating under different angles and pressures, resulting in an inability to fully reflect the performance of the coating in actual use. Therefore, a new coating material testing device and testing method have been developed. Summary of the Invention

[0005] The purpose of this invention is to provide a new coating material testing device and testing method to overcome the above-mentioned shortcomings in the prior art.

The testing assembly, which is mounted at the end of the adjustment plate, includes a conical block and a scraper for performing abrasion and flow tests on the coating. The conical block and the scraper cause wear interference to different parts of the bearing plate in different spatial postures, so that the coating can be tested for fluidity at cross-sections with different degrees of wear. At the same time, wear tests are carried out on the coating that has completed the fluidity test.

[0007] As a further optimization of the present invention, the simulation component further includes a limiting cylinder fixedly connected to the telescopic member, a positioning post fixedly provided on the inner wall of the limiting cylinder, and a positioning plate slidably provided on the outer surface of the positioning post; A disc is fixedly provided at the end of the limiting cylinder, and multiple sets of connecting blocks are uniformly rotatably arranged on the outer surface of the disc, with connecting rods fixedly provided at the ends of the connecting blocks.

[0008] As a further optimization of the present invention, a movable cylinder is slidably provided on the outer surface of the connecting rod, the end of the movable cylinder is fixedly connected to the end of the push block, and an extension ring is snapped onto the outer surface of the movable cylinder; An extension rod is rotatably provided on the outer surface of the extension ring, and the end of the extension rod away from the extension ring is rotatably connected to the outer surface of the positioning plate.

[0009] As a further optimization of the present invention, the detection component further includes a fixed cylinder that is engaged with the adjustment plate, an adjustment block is rotatably provided on the inner wall of the fixed cylinder, and a connecting ring is symmetrically fixed on the outer surface of the adjustment block; A fixing ring is fixedly provided on the outer surface of the fixing cylinder, and an adjusting rod is rotatably provided on the inner wall of the fixing ring. The end of the adjusting rod passes through and extends into the interior of the fixing cylinder, while an adjusting cylinder is slidably provided on the outer surface of the adjusting rod, and the outer surface of the adjusting cylinder is slidably connected to the inner wall of the adjusting block.

[0010] As a further optimization of the present invention, the inner wall of the connecting ring is fitted and slidably connected to the outer surface of the conical block, a pressing rod is slidably provided on the inner wall of the conical block, the outer surface of the pressing rod is slidably connected to the inner wall of the conical block, and a driving ring is snapped onto the outer surface of the pressing rod.

[0011] As a further optimization of the present invention, the end of the adjusting block is provided with a snap-fit ​​block, and the end of the snap-fit ​​block is fixedly provided with a snap-fit ​​plate.

[0012] As a further optimization of the present invention, a locking ring is fixedly provided on the outer surface of the fixed cylinder, a docking plate is slidably fitted on the inner wall of the locking ring, and a docking ring is fixedly provided on the inner wall of the docking plate.

[0013] As a further optimization of the present invention, a locking plate is slidably provided on the inner wall of the docking ring, and a ball is rotatably provided on the inner wall of the locking plate, the outer surface of the ball being fixedly connected to the end of the snap-fit ​​plate.

[0014] As a further optimization of the present invention, a support plate is fixedly provided at the end of the docking plate, the inner wall of the support plate is slidably connected to the outer surface of the scraper, and the outer surface of the scraper is fitted and slidably connected to the end of the locking plate.

[0015] A method for testing new coating materials, using the testing device described in any one of the above-mentioned methods, the testing method comprising the following steps: S1. The end of the pusher is designed as a wedge or spherical structure, which contacts and fits with the bottom of the support plate. When the pusher moves, its end can push the support plate to different positions, thereby changing the tilt angle of the support plate and simulating the flow behavior of the coating on different slope surfaces. This is used to test the leveling, anti-sagging and other flow performance indicators of the coating. S2. When the adjusting block rotates around the protrusion, the locking block drives the ball to rotate inside the locking plate through the locking plate. At the same time, the locking plate can slide along the docking ring to adapt to the angle change, so that the conical block can achieve precise positioning of any posture in three-dimensional space. S3. When axial pressure is applied to the pressing rod from the outside, the pressing rod drives the drive ring to move down synchronously. Since the drive ring abuts against the shoulder structure of the inner wall of the cone block, it can push the cone block to slide down relative to the connecting ring, thereby adjusting the contact pressure between the tip of the cone block and the coating surface, which is used to simulate the needs under different stress scenarios.

[0016] Compared with the prior art, the new coating material testing device and testing method provided by the present invention have the following beneficial effects: The simulation component features a flat section and a bent section on its support plate, with an adjustable angle between them. This allows for the simulation of paint flow behavior on complex surfaces such as corners and bends, comprehensively testing the paint's fluidity at different angles and replicating its flow characteristics on actual construction surfaces, thereby improving the accuracy of test results. Simultaneously, it can capture changes in the paint's abrasion resistance and adhesion in real time during the bending process, providing a precise testing method for evaluating the paint's resistance to cracking and peeling in stress concentration areas.

[0017] The testing components can be flexibly adjusted in position, supporting testing of tubular components from multiple angles and directions. They can also test the coating performance at bends, thereby more comprehensively simulating the performance of the coating in actual use and enhancing the evaluation of the wear resistance and adhesion of the pipe coating. In addition, the coating can be tested under different angles and pressures to simulate working conditions such as "weak adhesion" and "strong adhesion," thereby evaluating the wear resistance and reliability of the coating.

[0018] Through the coordinated operation of the simulation and detection components, wear testing and flowability testing can be carried out synchronously within the same device, following the same control logic. The detection end can perform continuous wear testing on the coating under different postures, realistically reproducing the wear resistance and adhesion performance of the coating under different adhesion states, effectively avoiding test condition deviations caused by switching between multiple devices; at the same time, it also makes the test data under different adhesion states and different flow angles quantitatively comparable, providing reliable data support for the optimization and evaluation of coating performance.

Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Example 1: Please refer to Figures 1-8 A new coating material testing device includes a testing platform 1, and an adjustment plate 11 is fixedly installed at the end of the testing platform 1.

[0024] In this scheme, the end of the adjustment plate 11 is provided with a telescopic component such as an electric telescopic rod, and is connected to an external control device. The adjustment plate 11 is adjusted by the electric telescopic rod, thereby changing the relative distance between the detection component 3 and the simulation component 2 to adapt to the detection requirements of coating specimens of different thicknesses, while ensuring that the cone block 34 and the scraper 391 can act on the coating surface with appropriate pressure.

[0025] Furthermore, the simulation component 2, which is assembled on the testing platform 1, includes a support plate 21 for carrying the coating and a telescopic component 22 and a push block 261 for adjusting the angle of the coating flow section. The push block 261 is driven by the telescopic component 22 to adjust its position, and the tilt angle of the support plate 21 is adjusted by the end of the push block 261, thereby realizing the flowability test of the coating.

[0026] In this embodiment, the telescopic component 22 is a component with telescopic function such as an electric telescopic rod. Its end is fixedly connected to the push block 261. The telescopic component 22 is driven to telescopically move by an external control device, thereby driving the push block 261 to move axially along the limiting cylinder 23.

[0027] The end of the push block 261 is designed as a wedge or spherical structure, which contacts and engages with the bottom of the support plate 21. When the push block 261 moves, its end can push the support plate 21 to different positions, thereby changing the tilt angle of the support plate 21.

[0028] The surface of the support plate 21 is provided with grooves or coating areas for placing coating samples. By adjusting its tilt angle, the flow behavior of coating on surfaces with different slopes can be simulated, thereby testing the leveling, anti-sagging and other flow performance indicators of the coating.

[0029] The movable ring 211 is connected to the external coating and supplies a quantitative amount of coating sample to the surface of the support plate 21 through the feeding system to ensure that the initial conditions of each test are consistent. The flat part and the bent part of the support plate 21 are detachably connected. The radius of curvature of the bent part can be changed according to the specifications of the tubular component to be simulated, so as to adapt to the simulation requirements of pipes with different diameters.

[0030] Furthermore, the simulation component 2 also includes a limiting cylinder 23 fixedly connected to the telescopic member 22. The inner wall of the limiting cylinder 23 is fixedly provided with a positioning post 28, and the outer surface of the positioning post 28 is slidably provided with a positioning plate 281. The end of the limiting cylinder 23 is fixedly provided with a disc 24, and the outer surface of the disc 24 is uniformly rotatably provided with multiple sets of connecting blocks 25, and the end of the connecting block 25 is fixedly provided with a connecting rod 251.

[0031] Specifically, the limiting cylinder 23 is a cylindrical structure with a guide groove on its inner wall along the axial direction. The positioning post 28 is fixedly installed at the bottom center of the limiting cylinder 23 (the positioning post 28 is a component with telescopic function such as an electric telescopic rod). The center of the positioning plate 281 has a through hole that cooperates with the positioning post 28, so that the positioning plate 281 can slide up and down along the positioning post 28.

[0032] The disc 24 is fixed to the top of the limiting cylinder 23 by bolts. Multiple hinge seats are evenly distributed on its outer circumference. Each hinge seat is rotatably connected to a connecting block 25 by a pin. The connecting block 25 can swing around the pin in the vertical plane. The connecting rod 251 is integrally formed or welded to the connecting block 25 and extends outward along the radial direction of the disc 24.

[0033] Furthermore, a movable cylinder 26 is slidably provided on the outer surface of the connecting rod 251, and the end of the movable cylinder 26 is fixedly connected to the end of the push block 261. At the same time, an extension ring 262 is snapped onto the outer surface of the movable cylinder 26. An extension rod 27 is rotatably provided on the outer surface of the extension ring 262, and the end of the extension rod 27 away from the extension ring 262 is rotatably connected to the outer surface of the positioning plate 281.

[0034] Specifically, the movable cylinder 26 is a hollow cylindrical structure, and its inner diameter matches the outer diameter of the connecting rod 251, so that the movable cylinder 26 can slide smoothly along the connecting rod 251; the end of the movable cylinder 26 facing the bearing plate 21 is fixedly connected to the bottom end of the push block 261 by thread or welding to form a linkage structure.

[0035] The extension ring 262 is a ring-shaped clamp structure, which is fixed to the middle of the outer surface of the movable cylinder 26 by bolts or buckles. It has a hinged ear plate on its outer circumference for rotating connection with one end of the extension rod 27.

[0036] The extension rod 27 is made of metal rod or high-strength composite material, and has ball joint or pin connection structure at both ends. When the positioning column 28 drives the positioning plate 281 to move axially, the positioning plate 281 drives the extension ring 262 and the moving cylinder 26 to slide along the connecting rod 251 through the extension rod 27, thereby changing the radial position of the push block 261.

[0037] Since multiple sets of connecting rods 251 are evenly distributed along the circumference, the coordinated movement of each push block 261 can enable the bearing plate 21 to achieve various spatial posture changes, including overall tilting, local bending or twisting deformation, thereby simulating the complex stress state of tubular components in actual use.

[0038] Furthermore, the testing component 3, which is assembled at the end of the adjustment plate 11, includes a conical block 34 and a scraper 391 for performing wear tests and flow tests on the coating. The conical block 34 and the scraper 391 cause wear interference to different parts of the bearing plate 21 in different spatial postures, so that the coating can be tested for flowability at cross-sections with different degrees of wear, while the coating that has completed the flowability test is subjected to wear tests.

[0039] In this embodiment, the conical block 34 is made of high-hardness alloy material, and its tip cone angle can be replaced according to test requirements to simulate wear sources with different sharpness; the scraper 391 is made of the same material as the conical block 34, and its edge is precision machined to form a cutting edge with a specific radius of curvature to simulate scraping wear conditions.

[0040] Furthermore, the detection assembly 3 also includes a fixed cylinder 31 that is snapped into the adjusting plate 11. An adjusting block 32 is rotatably disposed on the inner wall of the fixed cylinder 31, and a connecting ring 321 is symmetrically fixed on the outer surface of the adjusting block 32. A fixing ring 33 is fixedly disposed on the outer surface of the fixed cylinder 31, and an adjusting rod 331 is rotatably disposed on the inner wall of the fixing ring 33. The end of the adjusting rod 331 passes through and extends into the interior of the fixed cylinder 31. At the same time, an adjusting cylinder 332 is slidably disposed on the outer surface of the adjusting rod 331, and the outer surface of the adjusting cylinder 332 is slidably connected to the inner wall of the adjusting block 32.

[0041] Specifically, the fixed cylinder 31 is a cylindrical shell structure, and its outer surface is provided with a snap-fit ​​groove along the circumference to cooperate with the end of the adjusting plate 11, so that the fixed cylinder 31 can be quickly disassembled and assembled and angled relative to the adjusting plate 11; the inner wall of the fixed cylinder 31 is machined with a protrusion, which connects with the outer surface of the adjusting block 32, so that the adjusting block 32 can rotate around the protrusion.

[0042] The connecting ring 321 consists of two symmetrically arranged annular bosses, integrally formed with the adjusting block 32. Its outer diameter is in clearance fit with the inner diameter of the fixed cylinder 31, which serves both as an axial limiting function and to ensure the smooth rotation of the adjusting block 32. The inner wall of the connecting ring 321 has a tapered mating surface, which is used to form an interlocking sliding connection with the outer tapered surface of the tapered block 34.

[0043] The fixing ring 33 is fixed to the middle position of the outer surface of the fixing cylinder 31 by bolts; the adjusting rod 331 is a stepped shaft structure, with an external thread section in the middle that mates with the internal thread of the fixing ring 33, and a smooth guide section at the end. The adjusting rod 331 extends into the interior of the fixing cylinder 31 after passing through the fixing ring 33, and its end can be connected to an external rotary drive device to achieve precise angle adjustment. By rotating the adjusting rod 331, the adjusting block 32 can be driven to rotate circumferentially inside the fixing cylinder 31, thereby changing the relative angle position of the conical block 34 and the scraper 391 to adapt to the requirements of different test orientations.

[0044] The outer surface of the adjusting cylinder 332 is slidably connected to the inner wall of the adjusting block 32. By adjusting the position of the adjusting cylinder 332, the adjusting block 32 can be driven to rotate around the protrusion, thereby realizing the synchronous attitude adjustment or independent motion control of the conical block 34 and the scraper 391.

[0045] Furthermore, the inner wall of the connecting ring 321 is fitted and slidably connected to the outer surface of the conical block 34, and a pressing rod 341 is slidably provided on the inner wall of the conical block 34. The outer surface of the pressing rod 341 is slidably connected to the inner wall of the conical block 34, and a driving ring 342 is engaged on the outer surface of the pressing rod 341.

[0046] Specifically, the conical block 34 is a hollow conical structure, and the cone angle of its outer cone surface matches the cone angle of the inner wall of the connecting ring 321, so that the conical block 34 can be fitted and slid along the axial direction of the connecting ring 321.

[0047] A guide hole is provided at the center of the top of the cone block 34. The pressing rod 341 passes through the guide hole and forms a precise sliding fit with the cone block 34. The bottom end of the pressing rod 341 is provided with a snap-fit ​​groove that cooperates with the drive ring 342. The drive ring 342 is a ring structure and is fixed to the middle position of the outer surface of the pressing rod 341 by bolts. The end of the drive ring 342 is provided with a device with power output, such as a motor, to drive the pressing rod 341 to rotate.

[0048] When axial pressure is applied to the pressing rod 341, the pressing rod 341 drives the drive ring 342 to move downward synchronously. Since the drive ring 342 abuts against the shoulder structure of the inner wall of the conical block 34, it can push the conical block 34 to slide downward relative to the connecting ring 321, thereby adjusting the contact pressure between the tip of the conical block 34 and the coating surface. This pressure adjustment range can be quantitatively calibrated by replacing elastic elements with different stiffness or adjusting the drive stroke to meet the wear test requirements of coatings with different hardness.

[0049] Furthermore, a snap-fit ​​block 35 is snapped onto the end of the adjusting block 32, and a snap-fit ​​plate 351 is fixedly attached to the end of the snap-fit ​​block 35.

[0050] Specifically, the snap-fit ​​block 35 is a rectangular block structure, with a T-shaped snap-fit ​​protrusion at one end facing the adjustment block 32; a corresponding T-shaped slot is provided at the end of the adjustment block 32, which allows the snap-fit ​​block 35 and the adjustment block 32 to be quickly and detachably connected; the snap-fit ​​plate 351 is arranged perpendicularly to the snap-fit ​​block 35 and is integrally formed.

[0051] Furthermore, a locking ring 36 is fixedly provided on the outer surface of the fixed cylinder 31, and a docking plate 38 is slidably fitted on the inner wall of the locking ring 36, and a docking ring 381 is fixedly provided on the inner wall of the docking plate 38.

[0052] Specifically, the locking ring 36 is a circular ring structure, which is fixed to the lower part of the outer surface of the fixing cylinder 31 by welding or bolting. Its inner wall is provided with a T-shaped groove along the circumference for forming a sliding connection with the docking plate 38. The docking plate 38 is an arc-shaped plate structure, and its outer surface is provided with a T-shaped slider that cooperates with the T-shaped groove, so that the docking plate 38 can be adjusted and locked along the circumference of the locking ring 36.

[0053] The docking ring 381 is a ring structure and is fixed to the inner wall of the docking plate 38 by welding or integral molding. Its inner diameter matches the outer diameter of the ball 37 and is used to radially limit and axially support the ball 37.

[0054] Furthermore, a locking plate 371 is slidably provided on the inner wall of the docking ring 381, and a ball 37 is rotatably provided on the inner wall of the locking plate 371. The outer surface of the ball 37 is fixedly connected to the end of the snap-fit ​​plate 351.

[0055] Specifically, the locking plate 371 is an arc-shaped plate structure, and its outer surface is provided with a guide protrusion that can be adapted to the inner wall groove of the docking ring 381, so that the locking plate 371 can be adjusted in the radial direction of the docking ring 381; the inner wall of the locking plate 371 is machined with a spherical groove that matches the outer surface of the ball 37. After the ball 37 is embedded in the groove, it forms a ball hinge connection structure, which can realize multi-degree-of-freedom rotation.

[0056] The outer surface of the sphere 37 is fixed to the end of the snap-fit ​​plate 351 by threaded connection or welding, so that the snap-fit ​​plate 351 can adjust its spatial posture synchronously with the rotation of the sphere 37.

[0057] When the adjusting block 32 rotates around the protrusion, the locking block 35 drives the ball 37 to rotate within the locking plate 371 via the locking plate 351. At the same time, the locking plate 371 can slide along the mating ring 381 to adapt to angle changes. This composite motion structure allows the conical block 34 to achieve precise positioning in any posture in three-dimensional space, ensuring that the point of action of the wear test corresponds precisely to the coating flow test area.

[0058] Furthermore, a support plate 39 is fixedly provided at the end of the docking plate 38. The inner wall of the support plate 39 is slidably connected to the outer surface of the scraper 391, and the outer surface of the scraper 391 is fitted and slidably connected to the end of the locking plate 371.

[0059] Specifically, the pallet 39 adopts an L-shaped folded plate structure, with its horizontal section fixedly connected to the bottom end of the docking plate 38 by bolts, and its vertical section extending upward and having a rectangular guide groove; the scraper 391 is a long strip plate structure, with a rectangular slide rail on its outer surface that matches the guide groove of the pallet 39, so that the scraper 391 can slide up and down along the vertical direction of the pallet 39 for adjustment.

[0060] The upper outer surface of the scraper 391 is machined with a T-shaped fitting groove, which forms a sliding fit with the T-shaped slider corresponding to the end of the locking plate 371.

[0061] In the initial state, the bottom edge of the scraper 391 and the tip of the conical block 34 are at the same horizontal height. By adjusting the downward stroke of the pressing rod 341 and the sliding position of the scraper 391 respectively, the two can act on the coating surface alternately or simultaneously to achieve different working condition combinations for the joint test of wear and flowability.

[0062] The control device can choose a microcontroller as the control terminal. In this embodiment, the microcontroller is a typical embedded microcontroller unit, consisting of an arithmetic logic unit (ALU), a controller, memory, input / output devices, etc., essentially a miniature computer. Compared to general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings. Its biggest advantage is its small size, allowing it to be placed inside the instrument, but it has limited storage capacity, simple input / output interfaces, and low power consumption.

[0063] Example 2: A method for testing new coating materials, using any of the above-mentioned testing devices, the testing method includes the following steps: S1. The end of the push block 261 is designed as a wedge or spherical structure, which contacts and cooperates with the bottom of the support plate 21. When the push block 261 moves, its end can push the support plate 21 to different positions, thereby changing the tilt angle of the support plate 21, simulating the flow behavior of the coating on different slope surfaces, and thus testing the leveling, anti-sagging and other flow performance indicators of the coating. S2. When the adjusting block 32 rotates around the protrusion, the locking block 35 drives the ball 37 to rotate within the locking plate 371 through the locking plate 351. At the same time, the locking plate 371 can slide along the docking ring 381 to adapt to the angle change, so that the conical block 34 can achieve precise positioning of any posture in three-dimensional space. S3. When an axial pressure is applied to the pressing rod 341 from the outside, the pressing rod 341 drives the driving ring 342 to move down synchronously. Since the driving ring 342 abuts against the shoulder structure of the inner wall of the conical block 34, it can push the conical block 34 to slide down relative to the connecting ring 321, thereby adjusting the contact pressure between the tip of the conical block 34 and the coating surface to simulate the needs under different stress scenarios.

[0064] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.

10. A new method for testing coating materials, characterized in that, Using the detection device as described in any one of claims 1-9, the detection method includes the following steps: S1. The end of the push block (261) is designed as a wedge or spherical structure, which contacts and cooperates with the bottom of the support plate (21). When the push block (261) moves, its end can push the support plate (21) to different positions, thereby changing the tilt angle of the support plate (21) and simulating the flow behavior of the coating on different slope surfaces. This is used to test the leveling, anti-sagging and other flow performance indicators of the coating. S2. When the adjusting block (32) rotates around the protrusion, the snap-fit ​​block (35) drives the ball (37) to rotate in the locking plate (371) through the snap-fit ​​plate (351). At the same time, the locking plate (371) can slide along the docking ring (381) to adapt to the angle change, so that the cone block (34) can achieve precise positioning of any posture in three-dimensional space. S3. When an axial pressure is applied to the pressing rod (341) from the outside, the pressing rod (341) drives the driving ring (342) to move down synchronously. Since the driving ring (342) abuts against the shoulder structure of the inner wall of the cone block (34), it can push the cone block (34) to slide down relative to the connecting ring (321), thereby adjusting the contact pressure between the tip of the cone block (34) and the coating surface to simulate the needs under different stress scenarios.
