[0029] A conductive agent dispersibility test device, such as Figures 1 - 3As shown in the figure, it includes a test cylinder 10 for testing the dispersibility of conductive agents. A workbench 20 is provided at the bottom of the test cylinder 10. The top of the test cylinder 10 is an open structure, and a sealed top cover 11 is installed at the top opening. A stirring motor 12 is installed at the center of the top surface of the sealed top cover 11. A number of dispersibility test heads 13 are evenly arranged at equal intervals in a circular pattern at the edge of the bottom surface of the sealed top cover 11. The output shaft of the stirring motor 12 is connected to a stirring blade 14. On one side of the top surface of the workbench 20, a vertical frame 21 is installed. A horizontal frame 22 parallel to the bottom surface of the workbench 20 is installed on the top surface of the vertical frame 21. A lifting cylinder 30 is installed on the horizontal frame 22. The piston rod 31 of the lifting cylinder 30 is connected to the top of the stirring motor 12. By providing the test cylinder 10, a closed and stable test environment is provided for the dispersibility test of conductive agents, effectively avoiding the influence of external factors on the test results and ensuring the accuracy and reliability of the test. The stirring motor 12 at the center of the top surface of the sealed top cover 11, as the power source of the test device, drives the stirring blade 14 to work through its high-speed rotation, realizing the full stirring and dispersion of the conductive agent, which helps to accurately evaluate the dispersion performance of the conductive agent. The dispersibility test heads 13 evenly arranged at equal intervals in a circular pattern at the edge of the bottom surface of the sealed top cover 11 can monitor the dispersion state of the conductive agent during the stirring process from multiple angles and at multiple levels, improving the comprehensiveness and accuracy of the test. The application of the lifting cylinder 30 and its piston rod 31 realizes the automatic lifting function of the stirring motor 12 and the stirring blade 14, not only simplifying the test operation process but also improving the test efficiency.

[0030] It should be noted that the bottom area of the sealed top cover 11 is larger than the opening size of the test cylinder 10, so that the sealed top cover 11 can completely cover and press the opening of the test cylinder 10, effectively preventing the leakage of conductive agents or the entry of external impurities during the test.

[0031] Furthermore, a sealing gasket is provided on the bottom surface of the sealed top cover 11. The sealing gasket is made of rubber material and has a thickness of 2 - 4 mm, improving the sealing effect of the device.

[0032] Among them, the stirring motor 12 is embedded in the center of the bottom surface of the piston rod 31, so that the stirring motor 12 can be stably fixed on the piston rod of the lifting cylinder 30 and move with the lifting of the piston rod, thereby realizing the precise control of the height of the stirring blade 14.

[0033] Specifically, a homogenizing and dispersing tester 40 is installed on the top surface of the sealed top cover 11. Each group of dispersibility test heads 13 is connected to the homogenizing and dispersing tester 40, enabling the dispersibility test heads 13 to transmit the collected data to the homogenizing and dispersing tester 40 for processing and analysis in real time, thereby realizing the precise evaluation and monitoring of the dispersion performance of the conductive agent. The integration of the homogenizing and dispersing tester 40 improves the automation level and data processing efficiency of the test.

[0034] It should be noted that the number of the dispersion test heads 13 is 2 - 5 groups, which not only ensures the comprehensiveness of the test, but also avoids the complexity and increased cost brought by excessive test heads. By reasonably setting the number of the test heads, the dispersion performance of the conductive agent in different regions and at different angles can be effectively monitored, and the accuracy and reliability of the test can be improved.

[0035] In addition, shock-absorbing washers are installed at the bottom of the workbench 20. The shock-absorbing washers are made of silica gel material and have a thickness of 2 - 4 mm, which can effectively reduce the vibration and noise generated during the operation of the equipment, and protect the workbench 20 and the test equipment thereon from damage.

[0036] The working principle of this conductive agent dispersion test device:

[0037] (1) Place the test cylinder 10 stably on the workbench 20 to ensure that the test cylinder 10 is stable and without shaking, and pour an appropriate amount of conductive agent into the test cylinder 10.

[0038] (2) Install the sealing top cover 11 at the top opening of the test cylinder 10, start the stirring motor 12, and drive the stirring blade 14 to start rotating through its output shaft. The stirring blade 14 initially stirs the conductive agent in the test cylinder 10 to break the original agglomerated state of the conductive agent.

[0039] (3) Start the lifting cylinder 30, and drive the stirring motor 12 and the stirring blade 14 to move up and down through the piston rod 31. During the test, the height of the stirring motor 12 can be adjusted as needed to achieve the best stirring effect and test position.

[0040] (4) Under the continuous drive of the stirring motor 12, the stirring blade 14 fully stirs and disperses the conductive agent. At the same time, the dispersion test head 13 real-time monitors the dispersion state of the conductive agent, collects relevant data, and transmits it to the homogeneous dispersion tester 40 for subsequent analysis and evaluation.

[0041] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only the preferred examples of the present utility model, and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
