[0002] There are two methods for testing the viscosity of latex paint: the flow cup test and the Stormer viscometer test. For the flow cup test, first take a portion of the paint sample, prepare a flow cup, measure the temperature of the paint liquid, block the mouth of the cup with your left hand, fill the flow cup with paint liquid with your right hand, then release your left hand while simultaneously using a stopwatch to time the flow. Stop the stopwatch when the paint liquid has flowed out of the cup. The number of seconds displayed on the stopwatch is the viscosity of the paint liquid.
[0003] However, existing latex paint viscosity testing devices have the following problems during use: traditional workers use multiple sets of tools for testing, which results in low testing efficiency. In addition, they cannot measure the viscosity of multiple sets of paint in different milliliters, which makes the work efficiency low. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1, such as Figure 1-5As shown, this utility model provides a technical solution: a latex paint viscosity testing device, including a fixed frame 1, an upper support 4, and a splined shaft 9. The upper support 4 is installed at the top of the fixed frame 1, and a slide rail 5 is provided on the inner wall of the upper support 4. A sliding block 8 is provided inside the slide rail 5, and a splined shaft 9 penetrating the fixed frame 1 is installed inside the sliding block 8 through a bearing. A heating frame 2 is provided at the top of the inside of the fixed frame 1, and a detection cup 3 is placed inside the heating frame 2. A heating tube for conducting heat to detect the temperature of the detection cup 3 is provided on the inner wall of the heating frame 2. A transmission mechanism is installed at the top of the fixed frame 1 to provide transmission force for the splined shaft 9 to rotate up and down and left and right simultaneously. The transmission mechanism includes a rotating roller 10 and a second motor 15. The rotating roller 10 is installed at the top of the fixed frame 1 through a bearing, and the inner wall of the rotating roller 10 is provided with an arc-shaped groove. The device includes a positioning ball bearing 25 that contacts the outer wall of the splined shaft 9. A second motor 15 is mounted on the top of the fixed frame 1, and a transmission shaft 16 is mounted on the output end of the second motor 15 via a coupling. A transmission wheel 17 is sleeved on the outer wall of the transmission shaft 16, and a transmission belt 11 that passes through the rotating roller 10 is sleeved on the outer wall of the transmission wheel 17. A microcontroller 18 is mounted on the top of the second motor 15. Stirring scrapers 21 are spaced apart on the outer wall of the splined shaft 9. By starting the second motor 15, the transmission shaft 16 is driven to rotate, which in turn drives the transmission wheel 17 to rotate. The transmission wheel 17 then drives the rotating roller 10 to rotate via the transmission belt 11. Consequently, the splined shaft 9 drives the stirring scrapers 21 to rotate and stir within the test cup 3. This improves the uniformity of heating when heating and stirring the latex paint within the test cup 3, thus better meeting the viscosity test requirements.
[0025] Example 2, as Figure 1-6 As shown, this utility model provides a technical solution: a latex paint viscosity testing device, including a spline shaft 9 with multiple mounting grooves 12 at its bottom end, and a rubidium magnet 22 inside the mounting groove 12. A mounting block 19 adapted to the rubidium magnet 22 is installed inside the mounting groove 12, and a viscosity drop cup 20 for testing is installed on the outer wall of the mounting block 19. A threaded cap for permanently securing the bottom of the viscosity drop cup 20 is provided below it. A positioning groove 13 penetrating the mounting groove 12 is provided on the outer wall of the spline shaft 9, and a positioning screw 23 penetrating the outer wall slider of the mounting block 19 is threaded onto the outer wall of the positioning groove 13. The operator holds the viscosity drop cup 20 by hand, moving the rubidium magnet 22 at the mounting groove 12 of the mounting block 19 to a suitable position, and then rotates the positioning screw 23 through the outer wall slider of the mounting block 19 to facilitate the installation of viscosity drop cups 20 of different milliliters for testing.
[0026] Example 3, as Figure 1-6As shown, this utility model provides a technical solution: a latex paint viscosity testing device, including a timer 24 installed on the side wall of the fixed frame 1, a first motor 6 installed at the top of the upper bracket 4, and a lead screw 7 that passes through the sliding block 8 installed at the output end of the first motor 6 through a coupling. The outer wall of the lead screw 7 meshes with the inner wall of the sliding block 8. By starting the first motor 6, the lead screw 7 is driven to rotate, thereby the lead screw 7 drives the sliding block 8 to move up and down in the slide rail 5, so that the viscosity droplet cup 20 moves up and down in the testing cup body 3, meeting the test lifting requirements.
[0027] Working principle: First, connect the external power supply. The operator can put latex paint into the detection cup 3. Then, start the heating tube in the heating frame 2 to heat the latex paint in the detection cup 3. Next, start the first motor 6 to drive the lead screw 7 to rotate. The lead screw 7 drives the sliding block 8 to move up and down in the slide rail 5, so that the viscosity droplet cup 20 enters the detection cup 3. At this time, start the second motor 15 to drive the transmission shaft 16 to rotate. The transmission shaft 16 drives the transmission wheel 17 to rotate. The transmission wheel 17 drives the rotating roller 10 to rotate through the transmission belt 11. In turn, the spline shaft 9 drives the stirring scraper 21 to rotate and stir in the detection cup 3. When heating and stirring the latex paint inside the test cup 3, the uniformity of heating is improved. The temperature can be detected by the temperature sensor 14 located below the spline shaft 9. When the test temperature is reached, the information is fed back to the microcontroller 18. The microcontroller 18 can then start the first motor 6 to move the viscosity drop cup 20 upward. Then, the operator can wipe off the excess latex paint on the outer wall of the viscosity drop cup 20. After wiping, the threaded cap at the bottom of the viscosity drop cup 20 is opened, and the timer 24 is started to start timing. When multiple viscosity drop cups 20 are measured, multiple timers 24 are used to measure the viscosity, and the viscosity of the latex paint can be determined to be qualified.
[0028] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
