Description
Technical Field
[0001] This application relates to the field of powder performance technology, and in particular to a powder coating flowability testing device. Background Technology
[0002] Powder coatings are widely used materials in various industrial fields, including but not limited to pharmaceuticals, chemicals, food, cosmetics, plastics, ceramics, metals, and the production of the powder coating itself. The flowability of powder coatings is crucial to their processing and application effects. Flowability not only affects the delivery, mixing, spraying, and curing processes of the coating, but also directly relates to the quality and uniformity of the coating. Poor flowability of powder coatings can lead to problems such as nozzle clogging and uneven coating thickness during spraying, thus affecting the final quality and performance of the product. Therefore, accurately measuring and evaluating the flowability of powder coatings is of great significance for optimizing coating formulations, improving production processes, and enhancing product quality.
[0003] In related technologies, in traditional powder coating flowability testing devices, the inherent characteristics of powder coatings, such as uneven particle size distribution, varying moisture content, and diverse shapes, have a significant impact on the flowability of the coatings. These characteristics not only increase the complexity of the test but may also lead to inaccurate test results, thus requiring improvement. Utility Model Content
[0004] To address the issue of the influence of powder coating shape diversity on test results, this application provides a powder coating flowability testing device.
[0005] The powder coating flowability testing device provided in this application adopts the following technical solution:
[0006] A powder coating flowability testing device includes a testing frame with a conical body for loading powder coating on the frame. Inside the conical body is a dispersion mechanism for dispersing and curing the powder coating. The dispersion mechanism includes a dispersing rod, a stirring motor, and a rapping motor. The stirring motor and the rapping motor are both located at the top of the conical body. The rapping end of the rapping motor is connected to the conical body. The dispersing rod is connected to the output end of the stirring motor and is located inside the conical body, arranged along the length of the conical body. The testing frame is equipped with a shaking mechanism for agitating the conical body.
[0007] Due to the inherent characteristics of powder coatings, such as uneven particle size distribution, varying moisture content, and diverse shapes, their flowability is significantly affected. These characteristics not only increase the complexity of testing but may also lead to inaccurate test results. The above-mentioned technical solution, including a testing frame, a cone-shaped body mounted on the frame, and a dispersion mechanism installed inside the cone-shaped body, comprises a dispersing rod, a stirring motor, and a rapping motor. Before testing the flowability of the powder coating, the powder coating is poured into the cone-shaped body, and the stirring motor is started to rotate the dispersing rod. The dispersing rod's function is to thoroughly stir the powder coating inside the cone-shaped body, breaking up any agglomerates and making the particle size distribution more uniform. Simultaneously, the rapping motor, whose rapping end is connected to the cone-shaped body, is started, further promoting the dispersion and homogenization of the coating through vibration. This process combines stirring and rapping simultaneously. The shaking mechanism on the testing frame is activated. By shaking the cone, the mechanism helps to further break up agglomerates in the coating, improving its fluidity and achieving optimal dispersion. After the dispersion and shaking mechanisms have been running for a period of time (the specific time depends on the coating characteristics and testing requirements), all motors are stopped, and subsequent fluidity testing is performed. The dispersion stirrer, stirring motor, and rapping motor effectively agitate and vibrate the powder coating within the cone, breaking up clumps and agglomerates, resulting in a more uniform particle size distribution and improved fluidity. This contributes to obtaining more accurate and reliable test results in subsequent testing. Simultaneously, the testing process is simplified. Automated control of stirring, rapping, and shaking not only improves testing efficiency but also reduces the impact of human factors on the test results.
[0008] Optionally, the end of the dispersing rod is provided with a spiral part for unblocking the outlet of the cone body, the dispersing rod is arranged at the center of the cone body, and the spiral part is arranged towards the outlet of the cone body.
[0009] By adopting the above technical solution, the spiral part is integrally formed at the end of the dispersing agitator. The spiral part improves the stirring effect and guides the coating to flow smoothly to the outlet, ensuring that the coating flowability test process is not hindered. Its unique spiral shape can generate additional shear force and dispersing force, which helps to further refine the coating particles, improve the uniformity of coating dispersion, and ensure the accuracy of flowability test.
[0010] Optionally, a wall scraping plate is provided on the outer wall of the dispersing rod for scraping the wall, and the wall scraping plate abuts against the inner wall of the cone body.
[0011] By adopting the above technical solution, the scraper is installed on the dispersing rod. With the scraper set, the scraper abuts against the inner wall of the cone. As the dispersing rod rotates, the scraper can scrape and push the coating on the inner wall of the cone, so that it is fully mixed with the coating in the mixing center. This helps to break up the lumps and agglomerates in the coating, so that the coating forms a more uniform distribution in the cone. At the same time, it reduces the adhesion and accumulation of coating on the inner wall of the cone, thereby reducing the resistance to coating flow, keeping the cone clean, and extending its service life.
[0012] Optionally, a connecting rod is provided between the dispersing rod and the scraper plate for connection, and the two ends of the connecting rod are detachably connected to the dispersing rod and the scraper plate respectively.
[0013] By adopting the above technical solution, the scraper plate is installed on the dispersing and stirring rod via a connecting rod. The connecting rod makes the installation and disassembly of the scraper plate simple and quick. Disassembly and assembly can be easily completed by simply removing the connecting rod, without having to disassemble the entire dispersing and stirring rod, thus saving time and effort.
[0014] Optionally, the top of the cone body is provided with a flat cap, and a pressing member for fixing is provided between the flat cap and the cone body.
[0015] By adopting the above technical solution, the flat cap is installed on the top of the cone body. The flat cap is installed on the cone body through a pressing component. Through the setting of the flat cap and the pressing component, the design of the flat cap allows the operator to easily open and close the top of the cone body, which is convenient for cleaning and maintenance work inside the cone body. At the same time, the pressing component between the flat cap and the cone body can ensure a tight connection between the two, effectively preventing the powder coating from leaking from the top of the cone body during the mixing and testing process, which helps to maintain the stability and accuracy of the testing environment.
[0016] Optionally, the flat cylindrical cover is provided with a feeding port, and a loading bucket for easy feeding is provided at the opening of the feeding port.
[0017] By adopting the above technical solution, the feed inlet is opened through the flat cylinder cover, and the loading bucket is installed at the feed inlet. Through the setting of the feed inlet and the loading bucket, the design of the feed inlet allows the powder coating to enter the cone body conveniently through the inlet without complicated operation or tools. At the same time, the loading bucket provides a convenient container for holding and transporting the powder coating to the feed inlet, further simplifying the feeding process.
[0018] Optionally, the vibration mechanism includes a vibration seat, a vibration lead screw, a vibration motor, and a vibration block. The vibration lead screw is rotatably connected to the testing frame and is arranged along the height direction of the testing frame. The output end of the vibration motor is connected to the end of the vibration lead screw. The vibration block is slidably connected to the testing frame and is threadedly connected to the vibration lead screw. The vibration seat is connected to the vibration block, and the conical body is arranged on the vibration seat.
[0019] By adopting the above technical solution, the shaking mechanism includes a shaking seat, a shaking screw, a shaking motor, and a shaking block. While the cone body is being stirred and vibrated, the shaking mechanism on the testing frame is activated, the shaking motor is started, and the output shaft of the shaking motor begins to rotate, driving the shaking screw connected to it to rotate as well. The shaking block will move up and down along the height direction of the testing frame, and the shaking seat connected to the shaking block will also vibrate and rise accordingly. The cone body will also vibrate due to the influence of the shaking seat. The shaking mechanism further accelerates the dispersion process of the powder coating, reduces the time required for stirring and vibrating, helps improve testing efficiency, and allows the testing work to be completed more quickly.
[0020] Optionally, the shaking block is provided with a fixing rod, and the shaking seat is provided with two fixing plates, which are respectively connected to the two ends of the fixing rod along its length.
[0021] By adopting the above technical solution, the fixing rod is installed on the shaking block, and the shaking seat is fixed to the fixing rod through the fixing clamp. The fixing rod and the fixing clamp form a stable connection structure, which can ensure the stability of the shaking seat during the shaking process and withstand various forces and vibrations generated during the shaking process. The connection structure is stable and reliable.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] By using a dispersing agitator, stirring motor, and rapping motor, the powder coating inside the cone can be effectively stirred and vibrated, breaking up lumps and agglomerates in the coating, making the particle size distribution of the coating more uniform, and improving the fluidity of the coating. This helps to obtain more accurate and reliable test results in subsequent testing processes. At the same time, it simplifies the testing process. By automating the stirring, rapping, and shaking steps, it not only improves testing efficiency but also reduces the impact of human factors on test results.
[0024] The spiral section enhances the mixing effect and guides the coating smoothly to the outlet, ensuring unimpeded flow testing. Its unique spiral shape generates additional shear and dispersing forces, which helps to further refine the coating particles, improve the uniformity of coating dispersion, and ensure the accuracy of flow testing.
[0025] By setting up a shaking mechanism, the dispersion process of powder coatings can be further accelerated, reducing the time required for stirring and rapping, which helps to improve testing efficiency and allows the testing work to be completed more quickly. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0031] This application discloses a powder coating flowability testing device. (Refer to...) Figure 1 The powder coating flowability testing device includes a testing frame 1, on which a cone body 2 is installed. In this embodiment, the cone body 2 is designed in a cone shape and is used to hold the powder coating. The testing frame 1 is equipped with corresponding electronic scales, timers and other measuring and recording devices to test the flowability of the powder coating inside the cone body 2.
[0032] Reference Figure 2 The cone body 2 can be equipped with a sealing port at the bottom outlet, and a flat cover 7 is installed at the top opening of the cone body 2. The flat cover 7 covers the opening of the cone body 2, and a pressing member 71 is installed between the flat cover 7 and the cone body 2. In this embodiment, the pressing member 71 can be a clamp-type pressing member 71 (such as a U-shaped clamp or a V-shaped clamp). The design of the flat cover 7 allows the operator to easily open and close the top of the cone body 2, which is convenient for cleaning and maintenance inside the cone body 2. At the same time, the pressing member 71 between the flat cover 7 and the cone body 2 can ensure a tight connection between the two, effectively preventing the powder coating from leaking from the top of the cone body 2 during stirring and testing, which helps to maintain the stability and accuracy of the testing environment.
[0033] Reference Figure 2 A feed inlet 72 is provided through the flat cylindrical cover 7. A loading bucket 73 is installed and fixed at the feed inlet 72. The design of the feed inlet 72 allows the powder coating to enter the conical body 2 easily through the inlet without complicated operation or tools. At the same time, the loading bucket 73 provides a convenient container for holding and transporting the powder coating to the feed inlet 72, further simplifying the feeding process.
[0034] Reference Figure 2 The testing frame 1 is equipped with a shaking mechanism 4. In this embodiment, the shaking mechanism 4 is used to control the lifting and shaking of the cone body 2. The shaking mechanism 4 includes a shaking seat 41, a shaking screw 42, a shaking motor 43, and a shaking block 44. The shaking screw 42 is rotatably mounted on the testing frame 1 through a bearing. The shaking screw 42 is installed along the height direction of the testing frame 1. The shaking motor 43 is installed on the top of the testing frame 1. The shaking motor 43 can achieve forward and reverse rotation. The output end of the shaking motor 43 is connected to the end of the shaking screw 42.
[0035] Reference Figure 2 The vibrating block 44 is slidably connected to the testing frame 1, and is also threadedly connected to the vibrating screw 42. A fixing rod 8 is installed and fixed on the vibrating block 44, and two fixing plates 9 are installed and fixed on the vibrating seat 41. The two fixing plates 9 are respectively connected to the two ends of the fixing rod 8 along its length, thereby fixing the vibrating seat 41 and the vibrating block 44. At the same time, the cone body 2 is arranged and installed on the vibrating seat 41. When the vibrating mechanism 4 on the testing frame 1 is started, the vibrating motor 43 is started. The output shaft of the vibrating motor 43 begins to rotate, driving the vibrating block connected to it. When the moving lead screw 42 rotates together, the shaking block 44 will move up and down along the height direction of the detection frame 1. The shaking seat 41 connected to the shaking block 44 will also shake and move up and down accordingly. The cone body 2 will also shake due to the influence of the shaking seat 41. In this embodiment, the cone body 2 is raised and lowered by the forward and reverse rotation of the shaking motor 43, which in turn shakes the powder coating inside the cone body 2, which can accelerate the dispersion process of the powder coating, reduce the time required for stirring and rapping, help improve detection efficiency, and make the detection work more rapid.
[0036] Reference Figure 2 and Figure 3 The cone body 2 is equipped with a dispersion mechanism 3. In this embodiment, the dispersion mechanism 3 is used to disperse and cure powder coating. The dispersion mechanism 3 includes a dispersion stirring rod 31, a stirring motor 32 and a rapping motor 33. The stirring motor 32 and the rapping motor 33 are both arranged on the top of the cone body 2, and the rapping end of the rapping motor 33 is connected to the cone body 2.
[0037] Reference Figure 2 and Figure 3The dispersing rod 31 is rotatably installed inside the cone body 2. The dispersing rod 31 is arranged along the length of the cone body 2 and is located at the center of the cone body 2. The output end of the stirring motor 32 is connected to the end of the dispersing rod 31. At the same time, the end of the dispersing rod 31 is integrally formed with a spiral part 5. The spiral part 5 is arranged towards the outlet of the cone body 2. The spiral part 5 can guide the coating to flow smoothly to the outlet, ensuring that the flowability test of the coating is not hindered. Its unique spiral shape can generate additional shear force and dispersing force, which helps to further refine the coating particles, improve the dispersion uniformity of the coating, and ensure the accuracy of the flowability test.
[0038] Reference Figure 3 A scraper plate 6 is installed on the outer wall of the dispersing and stirring rod 31. The scraper plate 6 abuts against the inner wall of the cone body 2. At the same time, a connecting rod 61 is installed between the dispersing and stirring rod 31 and the scraper plate 6. The two ends of the connecting rod 61 are detachably connected to the dispersing and stirring rod 31 and the scraper plate 6, respectively. In this embodiment, there can be multiple sets of scraper plates 6. The scraper plate 6 can scrape and push the coating on the inner wall of the cone body 2, so that it is fully mixed with the coating in the stirring center. This helps to break up the lumps and agglomerates in the coating, so that the coating forms a more uniform distribution in the cone body 2. At the same time, it reduces the adhesion and accumulation of coating on the inner wall of the cone body 2, thereby reducing the resistance to the flow of coating, keeping the cone body 2 clean, and extending its service life.
[0039] The implementation principle of the powder coating flowability testing device in this application embodiment is as follows: Before testing the flowability of the powder coating, the powder coating is poured into the conical body 2, and the stirring motor 32 is started to make the dispersing rod 31 start rotating. The function of the dispersing rod 31 is to fully stir the powder coating in the conical body 2, break up the agglomerates in the coating, and make its particle size distribution more uniform. At the same time, the vibrating motor 33 is started. The vibrating end of the vibrating motor 33 is connected to the conical body 2. The vibration further promotes the dispersion and homogenization of the coating. While stirring and vibrating, the shaking mechanism 4 on the testing frame 1 is started. The shaking mechanism 4 helps to further break up the agglomerates in the coating by shaking the conical body 2, thereby improving the flowability of the coating. For optimal dispersion, after the dispersion mechanism 3 and the shaking mechanism 4 have been running for a period of time (the specific time is determined according to the coating characteristics and testing requirements), all motors are stopped, and subsequent flowability testing is performed. Through the dispersion stirring rod 31, stirring motor 32, and rapping motor 33, the powder coating within the cone 2 can be effectively stirred and vibrated, breaking up lumps and agglomerates in the coating, resulting in a more uniform particle size distribution and improved flowability. This helps obtain more accurate and reliable test results in subsequent testing processes. Simultaneously, the testing process is simplified. Automated control of stirring, rapping, and shaking steps not only improves testing efficiency but also reduces the impact of human factors on test results.
[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
