Description

Technical Field

[0001] This invention relates to the field of coating flowability testing technology, specifically to an inorganic coating flowability testing device. Background Technology

[0002] Testing the flowability of coatings is an important part of the pre-shipment testing process. Existing testing methods include the flow cup method, rotational viscometer method, thixotropic index test, flow ramp method, and scraper fineness meter method.

[0003] Chinese Patent Publication No. CN110243725B discloses an automatic powder flowability tester, comprising a powder fluidization container, a gas delivery path for powder to enter the fluidized state, a powder collection container, and a weighing mechanism for weighing the powder. One end of the gas delivery path is connected to a gas source, and the other end is connected to the powder fluidization container. The powder fluidization container has a powder outlet, which is connected to the powder collection container. The automatic tester includes an electrical control system, which includes a gas delivery path control unit and / or a powder outlet control unit. The gas delivery path control unit includes a gas switch controller module for controlling the automatic opening and closing of the gas delivery path, and a gas switch actuator for performing the opening and closing actions of the gas delivery path. The gas switch controller module inputs a control signal to the gas switch actuator, and the gas switch actuator is installed and connected to the gas delivery path.

[0004] The above scheme uses the flow cup method. However, after testing the same batch of paint, the container needs to be cleaned. Therefore, when dealing with large batches of paint, in order to avoid deviations in the test results, the container used to store the paint needs to be cleaned. However, the corners of the container are not easy to clean, so the time for cleaning the container each time is longer than the cleaning time of the slope in the flow ramp method. It cannot be applied to large batch testing. In addition, the slope in the traditional flow ramp method cannot be tested during cleaning, so the efficiency is still low. Summary of the Invention

[0005] To address the aforementioned issues, an inorganic coating flowability testing device is provided. By employing a dual-detection end face and a flip-up detection platform structure, it enables parallel execution of testing and cleaning operations, resolving the inefficiency caused by the interruption of cleaning and testing in traditional methods. After one batch of testing is completed on one detection end face, the detection platform can be flipped 180 degrees to switch to a clean detection end face for continued testing. Simultaneously, the cleaning unit cleans the lower end face where residual coating remains, eliminating the need to wait for cleaning to complete before starting the next batch of testing, significantly shortening the overall cycle for large-batch testing.

[0006] To address the problems of existing technologies, this invention provides an inorganic coating flowability testing device, comprising a feed pipe and a camera; It also includes a testing platform, a first rotary drive, and a cleaning unit; The testing platform is located below the feed pipe. The testing platform has two testing end faces for receiving the coating. A rotating shaft is fixedly installed in the middle of the testing platform, and the axis of the rotating shaft is parallel to the horizontal plane. The first rotary actuator is located at the end of the rotating shaft and is used to drive the rotating shaft to rotate. The cleaning unit is located below the testing platform and is used to clean the testing end face on the lower side of the testing platform.

[0007] Preferably, the detection device further includes a locking unit for locking the tilt angle of the detection stage, the locking unit including a locking groove and a locking block; The locking slots are divided into two groups and are respectively located at both ends of the testing table. The two groups of locking slots are arranged along the length of the testing table, and the locking slots in each group are arranged in an arc shape. There are two locking blocks, located on both sides of the testing table. The two locking blocks are arranged horizontally and can engage with the locking slots.

[0008] Preferably, the testing station has a frame structure and is made of lightweight rigid materials.

[0009] Preferably, both detection end faces on the detection platform are made of transparent material and both detection end faces are horizontal structures, with scale plates provided on the side of the two detection end faces that are close to each other.

[0010] Preferably, the cleaning unit includes a water sprayer and a sweeping brush; The water sprayer is located below the testing platform; The cleaning brush is mounted below the testing platform and rotates along its own axis, with the axis of the cleaning brush parallel to the axis of the rotating shaft.

[0011] Preferably, the cleaning unit further includes a drying roller, which is arranged parallel to one side of the cleaning brush.

[0012] Preferably, the cleaning unit further includes a support frame and a rotating frame; The support frame is located below the testing table and can move in both vertical and horizontal directions; The rotating frame is rotatably mounted on the support frame, and the sweeping brush and drying roller are also rotatably mounted on the rotating frame.

[0013] Preferably, two sets of springs are provided between the support frame and the rotating frame, and a hinge shaft is provided between the support frame and the rotating frame. The two sets of springs are respectively provided on both sides of the hinge shaft and arranged in the horizontal direction.

[0014] Preferably, the cleaning unit further includes a two-dimensional moving platform, which is connected to the support frame.

[0015] Preferably, a box is provided below the testing platform, and a ventilation fan is provided on the side wall of the box, so that airflow is generated inside the box when the ventilation fan is running.

[0016] The advantages of this invention compared to the prior art are: 1. This invention, by employing a dual-detection end face and a flip-up detection table structure, enables parallel execution of detection and cleaning operations, solving the inefficiency problem caused by the interruption of cleaning and detection in traditional detection methods. Once a batch of tests is completed on one detection end face, the detection table can be flipped 180 degrees to switch to a clean detection end face for continued testing. Simultaneously, the cleaning unit cleans the end face with residual paint on the lower side, eliminating the need to wait for cleaning to complete before starting the next batch of tests. This significantly shortens the overall cycle of large-batch testing, improves detection efficiency, and reduces the workload of repetitive operations for staff.

[0017] 2. By incorporating a locking unit and an optimized cleaning structure, the accuracy and stability of the test results are effectively guaranteed. After the testing platform is tilted to a specified angle, the locking block and the arc-shaped locking groove precisely engage, preventing the platform from shaking when the cleaning unit contacts the testing end face and ensuring that the tilt angle remains stable throughout the testing process. Simultaneously, the transparent testing end face, combined with an independent scale plate, avoids the problem of residual paint or paint peeling off the scale grooves and facilitates accurate acquisition of flow data by the camera. Furthermore, the dual drying guarantee of the drying roller and ventilation fan completely eliminates the interference of residues and water stains on the test results, significantly improving the testing accuracy compared to the traditional cup method and single-slope method.

[0018] 3. The lightweight design and automated cleaning mechanism reduce the operating load and maintenance costs of the device. The testing platform adopts a lightweight rigid frame structure, reducing the driving load of the first rotary drive and improving the smoothness of the flipping operation and the service life of the equipment. The cleaning unit, through the cooperation of a two-dimensional moving platform, rotating frame and spring assembly, can adapt to different tilt angles of the testing platform to achieve all-round cleaning without dead angles. The integrated automated operation of water spraying, sweeping and drying requires no manual intervention, which not only reduces labor costs but also avoids the operational differences caused by manual cleaning. At the same time, the centralized collection of waste liquid and the ventilation and dehumidification design of the tank make equipment maintenance more convenient and further reduce the overall testing cost.

[0032] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0033] Reference Figures 1-4 , Figure 7 and Figure 8 An inorganic coating flowability testing device includes a feed pipe 1 and a camera 2; It also includes a testing platform 3, a first rotary drive 33, and a cleaning unit 4; The testing platform 3 is located below the feed pipe 1. The testing platform 3 has two testing end faces 31 for receiving the coating. A rotating shaft 32 is fixedly installed in the middle of the testing platform 3. The axis of the rotating shaft 32 is parallel to the horizontal plane. The first rotary actuator 33 is disposed at the end of the rotating shaft 32, and the first rotary actuator 33 is used to drive the rotating shaft 32 to rotate. The cleaning unit 4 is located below the testing table 3. The cleaning unit 4 is used to clean the testing end face 31 on the lower side of the testing table 3.

[0034] In the field of coating flowability testing, the flow cup method has become one of the commonly used testing methods in the industry due to its intuitive operation principle and high data accuracy. However, in practical applications, the operational details of this method have a direct impact on the reliability of the test results, among which the container cleaning process is particularly critical. After completing the flowability test of the same batch of coatings, a thin film of coating will inevitably remain on the inner wall, rim, and outlet of the flow cup container used to hold the coating. These residues not only change the actual composition ratio of the coating in subsequent tests, but may also form lumps due to drying and solidification, hindering the normal flow of the coating and causing deviations in the test data, failing to accurately reflect the actual flowability index of the coating. Therefore, according to testing specifications, the container must be thoroughly cleaned after each batch of testing to ensure that there are no residues before proceeding to the next batch of testing.

[0035] However, when dealing with large-scale paint testing tasks, the cleaning requirements of the flow cup method have become increasingly limited. Paints generally have a certain degree of viscosity and adhesion, especially at the corners of the container, the seams of the inner wall, and the small discharge channels of the flow cup. These areas have relatively complex structures, making it difficult to completely remove residual paint through simple rinsing or wiping. To achieve a residue-free standard, operators need to use specialized cleaning tools, along with solvents, to repeatedly scrub and soak the container, and if necessary, dry it to ensure the inner wall of the container is restored to a clean state. This process significantly increases the time required; compared to the flow ramp method, which only requires rinsing and wiping the smooth ramp surface, the cleaning time for flow cup containers is often several times longer. This excessively long cleaning time directly leads to a longer interval between batch tests, making it difficult for the flow cup method to quickly complete testing tasks when facing large-scale, high-efficiency testing needs, severely limiting its application in large-scale testing scenarios.

[0036] It is worth noting that while the traditional flow ramp method is superior to the flow cup method in terms of ease of cleaning, it still fails to address the efficiency bottleneck of large-batch testing. The core testing component of the flow ramp method is a flat ramp panel. Cleaning only requires rinsing off residual paint with solvent and wiping with a clean cloth, making the cleaning process relatively simple and time-efficient. However, the problem lies in the fact that the entire testing ramp is unusable during the cleaning process. Operators must wait until the cleaning is completely finished and the ramp surface is dry before proceeding with the next batch of paint spreading and flowability testing. This means that the testing process is forced to be interrupted due to the cleaning operation, making continuous testing impossible. Even with a short cleaning time, frequent interruptions accumulate a significant amount of wasted time, resulting in consistently low overall testing efficiency, making it difficult to meet the demands of rapid quality inspection and timely production of large batches of paint in industrial manufacturing.

[0037] The inherent problems in the cleaning process of the two mainstream testing methods have led to a dilemma in large-scale coating flowability testing, where accuracy and efficiency are difficult to balance. The flow cup method requires a significant investment of time in container cleaning to ensure accuracy, sacrificing testing efficiency. While the traditional flow ramp method offers relatively simple cleaning, cleaning and testing cannot be performed simultaneously, limiting efficiency gains. This industry pain point not only increases companies' testing labor and time costs but may also impact production schedules.

[0038] To avoid the aforementioned situation, the existing detection device was optimized. The device now employs a flowing ramp method and has two detection end faces 31. When one detection end face 31 is in the detection state, the other is in the cleaning state. When the detection end face 31 in the detection state completes the detection, the detection table 3 rotates 180 degrees, causing the cleaned detection end face 31 to rotate to the upper side, and the detected end face 31 to rotate to the lower side. This improves detection efficiency and reduces the workload of the operators. The specific structure and working process of this invention are as follows: When testing the flowability of inorganic coatings, the feed pipe 1 is first opened, and a fixed amount of coating is dispensed onto the upper part of the testing platform 3, where it is received by the upper testing surface 31. At this time, the testing platform 3 is in a horizontal state. Subsequently, the first rotary actuator 33 drives the testing platform 3 to tilt according to the testing requirements. When the tilt reaches a specified angle, the first rotary actuator 33 stops operating, and the camera 2 detects the coating on the testing surface 31, that is, observes the flow distance of the coating per unit time. The first rotary actuator 33 is preferably a servo motor. During testing, it is assumed that the testing surface 31 at the bottom of the testing platform 3 is clean, that is, the testing surface 31 at the bottom of the testing platform 3 does not need to be cleaned at this time. Therefore, the cleaning unit 4 is not activated at this time. After the testing platform 3 completes the testing of a batch, the first rotary actuator 33 drives the testing platform 3 to rotate, so that the testing surface 31 receiving the coating faces upward, and the testing surface 31 that was originally located at the bottom is now located at the top. After the testing table 3 stops rotating, the cleaning unit 4 starts. The cleaning unit 4 cleans the testing end face 31 located on the lower side, while the testing end face 31 on the upper side can be tested simultaneously, which improves the testing efficiency.

[0039] Reference Figures 3-5 The detection device also includes a locking unit 5 for locking the tilt angle of the detection table 3. The locking unit 5 includes a locking groove 51 and a locking block 52. The locking slots 51 are divided into two groups and are respectively located at both ends of the testing table 3. The two groups of locking slots 51 are arranged along the length of the testing table 3, and the locking slots 51 in each group are arranged in an arc shape. Two locking blocks 52 are provided and located on both sides of the detection table 3 respectively. The two locking blocks 52 are arranged in a horizontal direction and can be engaged with the locking groove 51.

[0040] A servo cylinder is provided at the end of the locking block 52. Under the action of the servo cylinder, the two locking blocks 52 extend and retract synchronously in the horizontal direction. When the first rotary driver 33 drives the test table 3 to rotate, the locking block 52 is in a retracted state and disengages from the locking groove 51. At this time, the first rotary driver 33 can drive the test table 3 to rotate freely. When the test table 3 rotates to a specified angle, the two locking blocks 52 extend simultaneously and engage with the locking grooves 51 at both ends of the test table 3. This ensures that when the cleaning unit 4 cleans the test end face 31 at the bottom of the test table 3, the test table 3 will not rotate due to the contact of the cleaning unit 4. This also ensures that the tilt angle of the test end face 31 at the top of the test table 3 will not change due to the cleaning by the cleaning unit 4, thereby ensuring the accuracy of the coating fluidity test results.

[0041] Reference Figure 7 The testing platform 3 is a frame structure and is made of lightweight rigid materials.

[0042] By setting the detection stage 3 as a frame structure, the weight of the detection stage 3 is reduced, resulting in a smaller load when the first rotary driver 33 drives the detection stage 3 to rotate.

[0043] Reference Figure 6 and Figure 7 The two detection end faces 31 on the detection table 3 are made of transparent material and are both horizontal. A scale plate 34 is provided on the side of the two detection end faces 31 that are close to each other.

[0044] While directly setting the scale on the detection end face 31 facilitates detection by the camera 2, it hinders cleaning. Depending on the scale setting process, two scenarios may occur: First, if the scale is grooved and set on the detection end face 31, the camera 2 can detect the flow distance of the paint when it flows onto the surface, but subsequent cleaning is difficult, and paint residue may remain in the grooves. Second, if the scale is coated with pigment on the detection end face 31, while this ensures the surface is level, the pigment may fade during long-term cleaning, making it impossible for the camera 2 to recognize the scale. To avoid these issues, both detection end faces 31 are made of transparent material, and a scale plate 34 is set on each adjacent side of the two detection end faces 31. This avoids the problem of difficult-to-clean paint residue after detection and also prevents the scale from being washed away during long-term cleaning.

[0045] Reference Figure 9 and Figure 10 The cleaning unit 4 includes a water sprayer 41 and a sweeping brush 42; The water sprayer 41 is located below the testing platform 3; The cleaning brush 42 is rotatably positioned below the testing platform 3 along its own axis, and the axis of the cleaning brush 42 is parallel to the axis of the rotating shaft 32.

[0046] When the testing platform 3 rotates, the water sprayer 41 and the cleaning brush 42 are both positioned diagonally below the testing platform 3, ensuring that the rotation of the testing platform 3 is not obstructed by the water sprayer 41 and the cleaning brush 42. After the testing platform 3 completes its rotation, the locking unit 5 locks the testing platform 3, preventing it from rotating further. Subsequently, the water sprayer 41 and the cleaning brush 42 move to directly below the testing platform 3 and clean the testing end face 31 on the lower side of the testing platform 3. During cleaning, the water sprayer 41 first sprays water or cleaning fluid onto the testing end face 31, and then the cleaning brush 42 cleans the testing end face 31. It is worth noting that because the testing platform 3 is tilted during testing, the water or cleaning fluid sprayed onto the testing end face 31 on the lower side of the testing platform 3 cannot accumulate on the testing end face 31. A second rotary driver 43 is provided at the end of the cleaning brush 42 for driving the cleaning brush 42 to rotate; the second rotary driver 43 is preferably a servo motor.

[0047] Reference Figure 11 and Figure 12 The cleaning unit 4 also includes a drying roller 44, which is arranged parallel to one side of the cleaning brush 42.

[0048] When cleaning unit 4 cleans the detection end face 31, it first sprays water using sprayer 41, then sweeps the water-wetted detection end face 31 using cleaning brush 42, and finally wipes the cleaned detection end face 31 dry using wiping roller 44. By setting wiping roller 44, water stains can be avoided on the detection end face 31 after being swept by cleaning brush 42, ensuring that the test results will not be affected by water stains during the subsequent inorganic coating fluidity test. A transmission component 45 is set between wiping roller 44 and cleaning brush 42. The transmission component 45 can be selected as belt drive or gear drive according to the actual situation. By setting transmission component 45, synchronous drive of cleaning brush 42 and wiping roller 44 can be achieved with only one second rotary driver 43.

[0049] Reference Figure 6 , Figure 10 and Figure 12 The cleaning unit 4 also includes a support frame 46 and a rotating frame 47; The support frame 46 is located below the testing table 3, and the support frame 46 can move in both vertical and horizontal directions; The rotating frame 47 is rotatably mounted on the support frame 46, and the cleaning brush 42 and the drying roller 44 are both rotatably mounted on the rotating frame 47.

[0050] By setting a rotating frame 47 on the support frame 46, and rotatably mounting the rotating frame 47 on the support frame 46, when the support frame 46 drives the rotating frame 47 to approach the detection end face 31 at the lower part of the detection table 3, the cleaning brush 42 and the drying roller 44 can simultaneously contact the detection end face 31 under the support of the rotating frame 47. Subsequently, driven by the support frame 46, they move along the tilt direction of the detection table 3, thus ensuring that the cleaning brush 42 and the drying roller 44 can contact the detection end face 31 at the lower part of the detection table 3 regardless of how the tilt angle of the detection table 3 changes.

[0051] Reference Figure 6 Two sets of springs 48 are provided between the support frame 46 and the rotating frame 47. There is a hinge shaft between the support frame 46 and the rotating frame 47. The two sets of springs 48 are respectively provided on both sides of the hinge shaft and arranged in the horizontal direction.

[0052] By setting two sets of springs 48, it is ensured that the rotating frame 47 can be in a horizontal state when the cleaning brush 42 and the drying roller 44 are not in contact with the detection end face 31, and will not tilt on the support frame 46.

[0053] Reference Figure 7 The cleaning unit 4 also includes a two-dimensional moving platform 49, which is connected to the support frame 46.

[0054] Driven by the two-dimensional moving platform 49, the support frame 46 can move arbitrarily in the vertical and horizontal directions.

[0055] Reference Figure 3 and Figure 4 A housing 6 is installed below the testing platform 3, and a ventilation fan 61 is installed on the side wall of the housing 6. When the ventilation fan 61 is running, it creates airflow inside the housing 6.

[0056] After the cleaning unit 4 cleans the detection end face 31, the liquid from the cleaning process is collected and held by the housing 6. By creating airflow within the housing 6, excessive moisture accumulation is prevented, ensuring the dryness of the cleaned detection end face 31. Simultaneously, maintaining airflow within the housing 6 accelerates the evaporation of any remaining water stains on the detection end face 31 after wiping with the drying roller 44, allowing the detection end face 31 to dry quickly.

[0057] Working principle: First, confirm the status of each component of the testing device, ensuring that both testing end faces 31 are clean and dry, the scale plate 34 is clearly identifiable, the locking block 52 of the locking unit 5 is in the retracted state, the water sprayer 41, cleaning brush 42, and drying roller 44 of the cleaning unit 4 are located in a non-working position diagonally below the testing platform 3, and the ventilation fan 61 of the housing 6 is in standby mode. Prepare the inorganic coating to be tested, ensuring that the feed pipe 1 can accurately release a measured amount of coating.

[0058] After the device is started, the testing platform 3 is kept horizontal by default. The upper testing end face 31 is in the position to receive the coating, and the lower testing end face 31 is in a clean state and the cleaning unit 4 is not started. Open the feed pipe 1 and put a quantitative amount of coating into the testing end face 31 on the upper side of the testing platform 3. After the coating is completely put in, close the feed pipe 1.

[0059] The first rotary driver 33 starts, driving the inspection table 3 to rotate around the rotating shaft 32 to a preset tilt angle. When the inspection table 3 reaches the specified angle, the first rotary driver 33 stops running, and the servo electric cylinder drives the locking blocks 52 on both sides to extend synchronously and engage with the locking slots 51 at both ends of the inspection table 3 to firmly lock the tilt angle of the inspection table 3, so as to avoid the subsequent cleaning operation from affecting the inspection accuracy.

[0060] Camera 2 is aimed at the coating on the upper detection end face 31, and begins to monitor and record the flow distance of the coating along the scale plate 34 in real time, thus completing the data collection of the flowability test of this batch of coating.

[0061] After the batch of tests is completed, the servo electric cylinder drives the locking block 52 to retract and disengage from the locking slot 51. The first rotary driver 33 starts, causing the test table 3 to rotate 180 degrees, so that the test end face 31 with residual paint that has been tested rotates to the lower side, and the clean test end face 31 that was originally on the lower side rotates to the upper side and maintains the tilt angle. The locking unit 5 extends again to lock the test table 3.

[0062] After the lower residual paint detection end face 31 is in place, the two-dimensional moving platform 49 drives the support frame 46 to move the rotating frame 47, so that the cleaning unit 4 moves directly below the detection table 3. The water sprayer 41 first sprays water or cleaning fluid onto the detection end face 31, and then the second rotary drive 43 drives the cleaning brush 42 to rotate and clean through the transmission component 45. The drying roller 44 follows to wipe away the residual liquid and avoid water stains. During the cleaning process, the upper clean detection end face 31 simultaneously receives a new batch of paint, realizing parallel detection and cleaning.

[0063] The waste liquid generated during cleaning flows into the lower chamber 6 for centralized collection. At the same time, the ventilation fan 61 on the side wall of the chamber 6 is activated to create airflow inside the chamber 6, accelerating the evaporation of water stains on the lower detection end face 31 and ensuring that it quickly returns to a clean and dry state, preparing it for subsequent flipping and alternating use.

[0064] Repeat the above steps until all batches of paint have been tested. After testing, shut down all drive components and cleaning unit 4, clean the waste liquid from tank 6, and perform a comprehensive inspection and maintenance of the device.

[0065] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
