Description

Technical Field

[0001] This utility model relates to the field of dynamic testing platform technology, and in particular to a dynamic testing platform for composite organic clay thixotropic agents. Background Technology

[0002] In the field of coating additive production, composite organoclay thixotropic agents are core functional components that determine the application performance and storage stability of coatings. By constructing a three-dimensional network structure, they effectively regulate the rheological properties of coatings, preventing issues such as pigment sedimentation and stratification during storage. Furthermore, they control the flowability and thixotropic recovery rate of coatings during application (e.g., brushing, spraying, roller coating), ensuring uniform coating thickness and a smooth surface. Therefore, precise dynamic testing of the thixotropic properties of composite organoclay thixotropic agents (e.g., thixotropic index, low-temperature storage viscosity stability, and viscosity recovery time after shearing) during coating additive production is crucial for controlling product quality and optimizing production process parameters (e.g., clay modification degree and dispersant ratio), directly impacting the application effects and market competitiveness of downstream coating products.

[0003] In the production process of coating additives, each batch of thixotropic agent products needs to be sampled and tested, and each test must be completed with at least 3 parallel experiments to ensure data reliability. Some existing testing stations do not have a dedicated beaker centering and positioning mechanism designed for coating additive testing scenarios, and mainly rely on operators to manually move the beaker and visually judge whether the center of the beaker is aligned with the rotor rotation axis.

[0004] Because beakers used for testing coating additives are mostly open containers, positioning deviations are prone to occur during manual operation. In actual testing, the center of the beaker and the rotor axis are easily misaligned during repeated fixing. This alignment deviation directly changes the radial clearance between the rotor and the inner wall of the beaker, resulting in uneven flow field distribution of the coating binder fluid during shearing. This leads to excessively large dispersion in parallel experimental data for the same batch of samples, making it difficult to accurately reflect the true performance of the thixotropic agent. Therefore, this invention proposes a novel solution. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a dynamic testing platform for composite organic clay thixotropic agents. This platform can solve the problem that the center of the beaker and the rotor axis are easily misaligned. This misalignment will directly change the radial gap between the rotor and the inner wall of the beaker, resulting in uneven flow field distribution of the test fluid of the coating base during shearing, and excessive dispersion of parallel experimental data of the same batch of samples, which is not convenient to accurately reflect the true performance of the thixotropic agent.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a composite organic clay thixotropic agent dynamic testing platform, including a workbench and a beaker, with a testing instrument and a testing platform installed on the workbench; A beaker limiting assembly is set on the test bench. The beaker limiting assembly includes a connecting bracket, which is fixedly connected to the right end of the test bench. A connecting rod is slidably connected inside the connecting bracket, and a slide is fixedly connected to the surface of the connecting rod. A limiting block is fixedly connected to the end of the connecting rod away from the connecting bracket. A return spring is fitted onto the surface of the connecting rod, and the two ends of the return spring are fixed to the slide and the connecting bracket, respectively.

[0007] The surface of the test stand is provided with a sliding groove, and the slide is slidably connected to the sliding groove.

[0008] Preferably, the test bench is rotatably connected to a gear, and is slidably connected to a rack inside the test bench. The slide is fixedly connected to the rack, and there are two racks, both of which mesh with the gear.

[0009] Preferably, there are two sets of each of the slide groove, slide frame, connecting bracket, connecting rod, return spring, and limiting block.

[0010] Preferably, the upper end of the test platform is fixedly connected to four connecting columns, and the upper end of the test platform is provided with a movable frame. All four connecting columns can be fixedly connected to the movable frame, and the surface of the movable frame is provided with a limit groove.

[0011] Preferably, the upper end of the test platform is fixedly connected to a first guide frame and a second guide frame, and a mounting frame is slidably sleeved on the surface of the first guide frame and the second guide frame, with a limit bolt connected to the internal thread of the mounting frame.

[0012] Preferably, a drive motor is installed at the upper end of the mounting frame, the output end of the drive motor rotates through the mounting frame and is fixedly connected to a stirring paddle, and a torque sensor is installed at the lower end of the mounting frame.

[0013] Preferably, a beaker limiting sleeve is fitted onto the bottom of the beaker, and an anti-slip strip is fixedly connected to the surface of the beaker limiting sleeve.

[0014] Preferably, the movable frame is slidably sleeved on four connecting columns, and a threaded rod is rotatably connected to the upper end of the test platform, the threaded rod being threadedly connected to the movable frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This composite organic clay thixotropic agent dynamic testing platform, through the meshing transmission of internal gears and two racks, combined with the sliding of the slide along the groove, pushes one side of the limiting block to drive two sets of limiting blocks to synchronously approach and tightly fit the beaker. It can quickly achieve precise alignment between the center of the beaker and the rotation axis of the stirring paddle, completely solving the positioning deviation problem that is easy to occur when manually operating open beakers, avoiding the situation where the center of the beaker and the rotor axis are offset after multiple fixations, ensuring that the radial gap between the rotor and the inner wall of the beaker is stable and consistent, which is convenient for accurately reflecting the true performance of the thixotropic agent; 2. This composite organic clay thixotropic agent dynamic testing platform features a limiting groove on the surface of the movable frame that provides initial lateral constraint on the beaker. The beaker limiting sleeve fitted to the bottom of the beaker increases the friction with the movable frame through the surface anti-slip strip. At the same time, the return spring can buffer the lateral impact force of the fluid on the beaker during the test. The multiple limiting structure effectively prevents the beaker from sliding or tilting, ensuring that the flow field distribution is uniform when the stirring paddle shears the coating base fluid, avoiding the problem of flow field turbulence caused by beaker shaking.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Please see Figure 1-8 This utility model provides a technical solution: a composite organic clay thixotropic agent dynamic testing platform. The upper end of the workbench 1 is fixedly connected to the tester 2 and the test platform 3. The tester 2 is used to set test parameters, receive data and generate reports. The test platform 3 provides the installation and support foundation for each component. The two work together to realize the full process control of dynamic testing of thixotropic agents. The workbench 1 is made of high-strength metal material to improve the stability and durability of the overall structure.

[0023] The upper end of the test bench 3 is fixedly connected to a first guide frame 4 and a second guide frame 5. The mounting frame 6 is slidably sleeved on the surface of the first guide frame 4 and the second guide frame 5. The mounting frame 6 can slide up and down along the guide frame to adjust its height. The limiting bolt 7 is threaded on its surface. After the mounting frame 6 is adjusted to a suitable position, tightening the limiting bolt 7 can fix the mounting frame 6 through friction, ensuring that the position of the mounting frame is stable during the test.

[0024] The upper end of the mounting bracket 6 is fixedly connected to the drive motor 8. The output end of the drive motor 8 rotates through the mounting bracket 6 and is fixedly connected to the stirring paddle 10. A torque sensor 9 is installed at the lower end of the mounting bracket 6. The drive motor 8 provides rotational power to the stirring paddle 10, and the torque sensor 9 is used to detect the reaction torque during the stirring process in real time. The two work together to achieve shearing and data acquisition of the thixotropic agent fluid.

[0025] Four connecting posts 12 are fixedly connected to the upper end of the test platform 3. The movable frame 11 is slidably sleeved on the surface of the four connecting posts 12. A threaded rod 24 is rotatably connected to the upper end of the test platform 3. The threaded rod 24 is threadedly connected to the movable frame 11. Rotating the threaded rod 24 can drive the movable frame 11 to slide up and down along the connecting posts 12. The height of the movable frame 11 can be adjusted to fit beakers 13 of different capacities.

[0026] The surface of the movable frame 11 is provided with a limiting groove 14. When the beaker 13 is placed on the surface of the movable frame 11, the side wall of the beaker 13 fits against the limiting groove 14. The limiting groove 14 provides initial lateral constraint on the beaker 13. The bottom of the beaker 13 is fitted with a beaker limiting sleeve 23. The anti-slip strip on the surface of the beaker limiting sleeve 23 increases the friction with the movable frame 11, preventing the beaker 13 from sliding or tilting.

[0027] The test bench 3 is internally connected to a gear 15, and two racks 16 mesh with the gear 15. The surface of the test bench 3 is provided with a sliding groove 17. The slide 18 is slidably connected to the sliding groove 17 and fixedly connected to the rack 16. The connecting bracket 19 is fixed to the right end of the test bench 3. The connecting rod 20 is slidably connected inside the connecting bracket 19 and fixed to the slide 18. The limiting block 22 is fixed to the end of the connecting rod 20 away from the connecting bracket 19. The return spring 21 is sleeved on the surface of the connecting rod 20.

[0028] Pushing one side limit block 22 can drive the connecting rod 20, slide 18 and rack 16 to move. Through the gear 15, the other side rack 16 moves in the opposite direction synchronously, so that the two sets of limit blocks 22 can move close to the beaker 13 and fit tightly, and complete the precise alignment of the center of the beaker 13 with the rotation axis of the stirring paddle 10. The reset spring 21 will reset the limit block 22 when it is not under force.

[0029] Working principle: The operator first places the beaker 13 containing the test fluid, which is a composite organic clay thixotropic agent for coating additives, on the surface of the movable frame 11 supported by four connecting columns 12 at the upper end of the test platform 3, and makes the side wall of the beaker 13 initially fit with the limiting groove 14 opened in the movable frame 11. The limiting groove 14 can provide initial lateral constraint on the beaker 13 to avoid large displacement during placement.

[0030] Inside the test bench 3, two sets of symmetrically arranged grooves 17 provide sliding tracks for the slide 18. One end of the slide 18 is fixedly connected to the rack 16, and the other end is fixed to the surface of the connecting rod 20. When the beaker 13 is placed, if there is a positional shift, the operator can push the limiting block 22 on either side. The limiting block 22 causes the connecting rod 20 to slide along the inside of the connecting bracket 19. At the same time, the connecting rod 20 causes the slide 18 to slide along the groove 17, and the slide 18 synchronously drives the rack 16 to move. Since both racks 16 are rotatably connected to the inside of the test bench 3... When gear 15 meshes, the movement of one side rack 16 will drive the other side rack 16 to move synchronously in the opposite direction through gear 15, thereby causing the two sets of slides 18, connecting rods 20 and limiting blocks 22 to move synchronously towards beaker 13 until the two limiting blocks 22 are tightly fitted with the side wall of beaker 13, achieving precise alignment between the center of beaker 13 and the rotation axis of subsequent stirring paddle 10; during this process, the return spring 21 sleeved on the surface of connecting rod 20 can maintain the initial position when the limiting block 22 is not under force, preventing the limiting block 22 from shifting in the non-operation state.

[0031] The first guide frame 4 and the second guide frame 5 fixed at the upper end of the test bench 3 provide vertical sliding support for the mounting frame 6. The operator can loosen the limiting bolt 7 connected to the thread on the surface of the mounting frame 6 and push the mounting frame 6 to slide up and down along the first guide frame 4 and the second guide frame 5 until the stirring paddle 10 at the lower end of the mounting frame 6 extends into the fluid to be tested inside the beaker 13 and reaches the preset immersion depth. Then tighten the limiting bolt 7 to fix the position of the mounting frame 6 by the friction between the limiting bolt 7 and the first guide frame 4, ensuring that the height of the stirring paddle 10 is stable during the test.

[0032] The drive motor 8 mounted on the upper end of the mounting bracket 6 provides rotational power for the agitator 10. The operator sets the speed parameters of the drive motor 8 through the tester 2 on the workbench 1. At the same time, the tester 2 establishes a data connection with the torque sensor 9 at the lower end of the mounting bracket 6. The model is Althen Sensors ATF326. The torque sensor 9 has a rated torque of 20 N·m, a nonlinearity of ±0.1%RT, a hysteresis of ±0.4%RT, and an operating temperature range of -10℃ to +80℃. It is installed between the drive motor 8 and the mounting bracket 6. The motor shaft of the drive motor 8 passes through the center of the torque sensor 9. The shaft torque of the agitator 10 can be indirectly obtained by measuring the reaction torque of the stator of the drive motor 8. This is suitable for the accurate measurement requirements of agitation torque in the clay thixotropic agent detection scenario. During debugging, it is necessary to ensure stable data transmission between the torque sensor 9 and the tester 2.

[0033] After the parameters are set, the tester 2 starts the drive motor 8. The output of the drive motor 8 drives the stirring paddle 10 to rotate. The stirring paddle 10 rotates in the thixotropic agent fluid to be tested in the beaker 13 at the set speed, generating a shearing effect on the fluid. During the rotation, since the beaker 13 is double-fixed by the limiting block 22 and the limiting groove 14, and the return spring 21 can buffer the lateral impact force of the fluid on the beaker 13, the beaker 13 is effectively prevented from shaking, ensuring that the relative shear state between the stirring paddle 10 and the fluid is stable.

[0034] As the stirring paddle 10 rotates, the thixotropic agent fluid generates a reaction torque on the stirring paddle 10. This torque is transmitted to the torque sensor 9 through the stator of the drive motor 8. The torque sensor 9 converts the detected reaction torque signal into an electrical signal and transmits it to the tester 2 in real time. At the same time, the tester 2 can record torque data according to the set time interval and, combined with the real-time rotation speed of the drive motor 8, calculate key performance parameters such as viscosity and thixotropic index of the thixotropic agent fluid.

[0035] Once the test reaches the preset duration, the tester 2 automatically controls the drive motor 8 to stop, simultaneously halting torque data acquisition. It then analyzes and processes the acquired torque and speed data to generate a thixotropic agent dynamic performance test report. Operators can view or export the data through the tester 2 interface.

[0036] The operator releases the limit block 22, and the reset spring 21 drives the connecting rod 20, the slide 18 and the rack 16 to reset, so that the limit block 22 is removed from the beaker 13. Then the beaker 13 is removed, the thixotropic agent fluid remaining on the surface of the stirring paddle 10 is cleaned, the limit bolt 7 is loosened and the mounting bracket 6 is adjusted to the initial height, completing the equipment reset for one test cycle and preparing for the next batch of thixotropic agent tests.

[0037] Furthermore, through the meshing transmission of the gear 15 and the two racks 16 inside the test bench 3, and in conjunction with the sliding of the slide 18 along the slide groove 17, pushing one side of the limiting block 22 can drive the two sets of limiting blocks 22 to move closer to the beaker 13 and fit tightly together. This can quickly achieve precise alignment between the center of the beaker 13 and the rotation axis of the stirring paddle 10, completely solving the positioning deviation problem that is easy to occur when manually operating open beakers, avoiding the situation where the center of the beaker and the rotor axis are offset after multiple fixations, and ensuring that the radial clearance between the rotor and the inner wall of the beaker is stable and consistent.

[0038] The limiting groove 14 on the surface of the movable frame 11 can provide initial lateral constraint on the beaker 13. The beaker limiting sleeve 23 fitted at the bottom of the beaker 13 increases the friction with the movable frame 11 through the surface anti-slip strip. At the same time, the return spring 21 can buffer the lateral impact force of the fluid on the beaker 13 during the test. The multiple limiting structure effectively prevents the beaker 13 from sliding or tilting, ensuring that when the stirring paddle 10 shears the coating base fluid to be tested, the flow field distribution is uniform, avoiding the problem of flow field disorder caused by beaker shaking.

[0039] Example 1: Anti-slip stability test example based on beaker limiting sleeve (adapted to high viscosity thixotropic agent testing scenario) In the production of coating additives, when testing high-viscosity composite organic clay thixotropic agents, the high-speed rotation of the stirring paddle 10 will cause the fluid to generate strong centrifugal force, which can easily lead to relative sliding between the bottom of the beaker 13 and the surface of the movable frame 11, and even the risk of the beaker 13 tilting, affecting the accuracy of torque data acquisition. In this embodiment, the problem of beaker stability during high-viscosity fluid testing is solved by attaching a beaker limiting sleeve 23 to the bottom of the beaker 13 and optimizing the anti-slip structure.

[0040] Select a beaker limiting sleeve 23 that matches the outer diameter of the bottom of beaker 13. The sleeve is made of oil-resistant rubber and has anti-slip texture on the inner wall. Fit it tightly onto the bottom of beaker 13 to ensure that the upper edge of the beaker limiting sleeve 23 fits snugly against the bottom side wall of beaker 13 without gaps.

[0041] Anti-slip strips are integrally formed on the outer wall and bottom of the beaker limiting sleeve 23. The anti-slip strips on the outer wall are evenly distributed along the circumference, and the anti-slip strips on the bottom are arranged in a grid pattern.

[0042] The operator places the beaker 13 with the beaker limiting sleeve 23 attached into the limiting groove 14 of the movable frame 11, so that the bottom of the beaker limiting sleeve 23 is in complete contact with the surface of the movable frame 11, and the outer anti-slip strip is tightly fitted with the inner wall of the limiting groove 14.

[0043] Start the drive motor 8 and use the stirring paddle 10 to perform a dynamic shear test on the high viscosity thixotropic agent sample; because the grid-like anti-slip strip at the bottom of the beaker limiting sleeve 23 increases the friction with the surface of the movable frame 11, and the outer wall anti-slip strip and the limiting groove 14 form a "concave-convex fit", the radial displacement of the beaker 13 is restricted, preventing the beaker 13 from sliding or tilting.

[0044] The torque sensor 9 (AlthenSensorsATF326) collects stirring torque data in real time. After the test, the beaker 13 can be directly removed from the beaker limiting sleeve 23 for cleaning. The beaker limiting sleeve 23 is reusable and can be used to test different batches of high-viscosity thixotropic agents, reducing consumable costs.

[0045] Example 2: Multi-position limit test implementation based on adjustable frame height (adapted to test scenarios with beakers of different capacities) In the production testing of coating additives, beakers 13 of different capacities are required depending on the amount of thixotropic agent sample. The height of beakers 13 of different capacities varies greatly. The movable frame 11 with a fixed height cannot effectively limit the middle or upper part of the beaker 13, causing the beaker 13 to easily "shake up and down" during the test. In this embodiment, the movable frame 11 is slidably connected to the connecting column 12, and the height is adjusted by the threaded rod 24 to achieve multi-position limiting of beakers 13 of different capacities.

[0046] Four connecting columns 12 are vertically fixed to the upper end of the test bench 3. The movable frame 11 has four sliding holes that match the connecting columns 12, so that the movable frame 11 can slide smoothly up and down along the connecting columns 12 through the sliding holes.

[0047] At the upper end of the test bench 3, near the connecting column 12, a threaded rod 24 is rotatably connected via a bearing. The upper end of the threaded rod 24 passes through the movable frame 11 and is threadedly connected to the movable frame 11. A knob is fixedly installed at the top of the threaded rod 24.

[0048] After beaker 13 is placed in, limiting groove 14 limits the lower part of beaker 13 to prevent the bottom of large-capacity beaker 13 from shifting due to the large weight of liquid. The viscosity data is collected by torque sensor 9.

[0049] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
