[0004] With respect to the above-mentioned related technologies, when it is necessary to test the viscosity of latex paint at multiple different temperatures, the latex paint needs to be repeatedly heated or cooled and then re-measured, which makes the measurement process more complicated and leads to poor test results. Summary of the invention

[0008] By adopting the above technical scheme, when it is necessary to test the viscosity of latex paint, the latex paint is poured into the device container and the test cylinder is driven. The piston rod of the test cylinder drives the test instrument to move toward the device container until all the test components enter the device container. The heating module is started to heat the latex paint in the device container. When the latex paint in the device container is heated to different temperatures at different heights, each test component performs viscosity tests on the latex paint at different heights, and then sends the multiple test signals to the test instrument. The test instrument then displays the viscosity value and temperature value of each test component corresponding to the different temperatures of the latex paint height, thereby completing the test of the viscosity value of the latex paint at multiple temperatures. This improves the problem that when it is necessary to test the viscosity of latex paint at multiple different temperatures, the latex paint needs to be repeatedly heated or cooled and then re-measured, which makes the measurement process more cumbersome and leads to poor test results.

[0014] By adopting the above technical solution, when the latex paint in the device container needs to be stirred, the rotating motor is driven, and the output shaft of the rotating motor drives the rotating bevel gear to rotate, and the rotating bevel gear drives the rotating bevel gear disk to rotate, and the rotating bevel gear disk drives the test rod to rotate, and the rotation of the test rod drives each rotating rod to rotate circumferentially around the axis of the test rod, so that the rotating rod stirs the latex paint, so that the test device does not need to add an additional stirring structure, which makes the manufacturing simpler and more convenient, and makes the practicality better.

[0015] Optionally, each two adjacent test components are located on two sides of the test rod respectively.

[0016] By adopting the above technical solution, each adjacent test assembly is located on both sides of the test rod, so that when the rotating assembly drives the test rod to rotate, each rotating rod stirs in multiple directions at the same time. Each rotating rod has a better stirring effect on latex paint, making it more usable.

[0017] Optionally, the testing mechanism also includes a linkage assembly, which includes a plurality of linkage ratchets, a linkage wheel, a plurality of linkage pawls, a plurality of linkage springs and a linkage motor, each of the linkage ratchets being coaxially fixed with each driving worm, the linkage wheel being rotatably arranged on the testing instrument, each of the linkage pawls being rotatably arranged on the linkage wheel, each of the linkage pawls being respectively meshed with two linkage ratchets, one end of each linkage spring being fixedly connected to each linkage pawl, the other end of each linkage spring being fixedly connected to the linkage wheel, the linkage motor being fixedly arranged on the testing instrument, and the output shaft of the linkage motor being coaxially fixed with the linkage wheel.

At the same time, the refrigeration modules are divided into multiple groups and controlled separately, so that the latex paints at different heights in the device container are cooled separately, so that the latex paints at different heights have different temperatures, thereby realizing a single test of the viscosity data of multiple groups of latex paints in a low temperature environment, making it easier to use.

The heating module is started to heat the latex paint in the device container. When the latex paint in the device container is heated to different temperatures at different heights, each test component performs viscosity tests on the latex paint at different heights, and then sends the multiple test signals to the test instrument. The test instrument then displays the viscosity value and temperature value of each test component corresponding to the latex paint at different temperatures, thereby completing the test of the viscosity value of the latex paint at multiple temperatures. This improves the problem that when it is necessary to test the viscosity of multiple latex paints at different temperatures, the latex paint needs to be repeatedly heated or cooled and then re-measured, which makes the measurement process more cumbersome and leads to poor test results.

When the viscosity of latex paint needs to be tested, the temperature sensor is started, and the temperature sensor transmits the detected temperature of the latex paint to the testing instrument. The connecting rod rotates, and the rotation of the connecting rod drives the rotating rod to rotate through the connecting spring.

The external mechanism 1 includes a mounting frame 11, a mounting base 12 and a device container 13. The mounting base 12 is fixedly arranged at the bottom of the mounting frame 11. The mounting base 12 includes a mounting portion 121 and a surrounding portion 122. The mounting portion 121 and the surrounding portion 122 are fixedly connected. The mounting portion 121 is provided with a heating module, and the surrounding portion 122 is provided with a cooling module. The device container 13 is cylindrical. The device container 13 is arranged on the side of the mounting base 12 close to the mounting frame 11. The side of the device container 13 close to the mounting base 12 abuts against the mounting portion 121, and the outer peripheral surface of the device container 13 abuts against the surrounding portion 122. A receiving groove is opened on the side of the device container 13 away from the mounting base 12. In the embodiment of the present application, the receiving groove is used to receive latex paint.

[0040] The setting of the heating module allows the device container 13 to heat the latex paint in the receiving tank when it is set on the mounting base 12. By controlling the heating time, the latex paint in the device container 13 is heated to different temperatures at different heights, thereby facilitating the subsequent latex paint viscosity test. At the same time, the setting of the refrigeration module allows the temperature of the device container 13 to be lowered when it is necessary to test the viscosity performance of the latex paint in a cold environment, thereby completing the reduction of the temperature of the latex paint, thereby realizing the viscosity test of the latex paint in a low temperature environment. At the same time, the refrigeration modules are divided into multiple groups and controlled separately, so that the latex paints at different heights in the device container 13 are cooled separately, so that the latex paints at different heights have different temperatures.

[0042] Reference Figure 1 and Figure 2 The test mechanism 2 includes a test cylinder 21, a test instrument 22, a test seat 23 and a sealing cover 24.

A sealing gasket is fixedly arranged on the side of the sealing cover 24 away from the test seat 23. When the piston rod of the test cylinder 21 drives the test instrument 22 to move toward the device container 13, the sealing cover 24 seals the receiving groove, and the sealing gasket abuts and cooperates with the device container 13.

[0043] When the test device is tested, the test cylinder 21 is driven, and the piston rod of the test cylinder 21 drives the test instrument 22 to move toward the device container 13, the test instrument 22 drives the test seat 23 to move toward the device container 13, and the test seat 23 drives the sealing cover 24 to move toward the device container 13 until the sealing point abuts against the device container 13, thereby completing the sealing of the containing tank, so that during the test, the latex paint contained in the containing tank is not easy to splash out of the containing tank.

[0044] Reference Figures 2 to 5A test cavity is provided in the middle of the test seat 23. The test mechanism 2 also includes a rotating assembly 25 and a test rod 26. The rotating assembly 25 includes a rotating bevel gear 251, a plurality of rotating bevel gears 252 and a rotating motor 253. The rotating bevel gear 251 is rotatably arranged at the bottom of the test cavity. The test rod 26 is cylindrical. The test rod 26 is coaxially fixedly connected to the rotating bevel gear 251 on the side close to the bottom of the test cavity. The end of the test rod 26 away from the rotating bevel gear 251 is located in the accommodating groove. Each rotating bevel gear 252 is rotatably arranged at the bottom of the test cavity. Each rotating bevel gear 252 is meshed with the rotating bevel gear 251. The rotating motor 253 is fixedly arranged at the bottom of the test cavity. The output shaft of the rotating motor 253 is coaxially fixed with one of the rotating bevel gears 252.

[0045] When the test rod 26 needs to rotate, the rotating motor 253 is driven, and the output shaft of the rotating motor 253 drives one of the rotating bevel gears 252 to rotate, and the rotating bevel gear 252 drives the rotating bevel gear plate 251 to rotate, and the rotating bevel gear plate 251 rotates, thereby completing the driving of the test rod 26 to rotate.

[0046] Reference Figures 2 to 5 The testing mechanism 2 also includes a linkage assembly 27, which includes two linkage ratchet wheels 271, a linkage wheel 272, a plurality of linkage pawls 273, a plurality of linkage springs 274 and a linkage motor 275.

[0047] Reference Figure 2 and Figure 6 The test mechanism 2 also includes a driving assembly 28, which includes a plurality of driving worm wheels 281 and two driving worms 282. Each driving worm wheel 281 is rotatably disposed on the test rod 26, and the two driving worms 282 are rotatably disposed on the test rod 26. The two driving worms 282 are coaxially fixedly connected to the two linked ratchet wheels 271, respectively, and each driving worm wheel 281 is respectively engaged with the two driving worms 282.

[0048] When the driving worm wheel 281 needs to rotate, the linkage motor 275 is driven, and the output shaft of the linkage motor 275 drives the linkage wheel 272 to rotate, and the linkage wheel 272 rotates to drive the linkage pawl 273 to rotate, and the linkage pawl 273 rotates to drive the two linkage ratchet wheels 271 to rotate, and the two linkage ratchet wheels 271 rotate to respectively drive the two driving worms 282 to rotate, and the two driving worms 282 rotate to respectively drive the driving worm wheels 281 to rotate, thereby completing the driving of the driving worm wheels 281. At the same time, when the rotating component 25 needs to drive the test rod 26 When rotating, the test rod 26 rotates, and the rotation of the test rod 26 drives each driving worm 282 to rotate circumferentially around the axis of the test rod 26, and each driving worm 282 drives each linkage ratchet 271 to rotate circumferentially around the axis of the linkage wheel 272. When each linkage ratchet 271 rotates circumferentially around the axis of the linkage wheel 272, it is difficult to drive the linkage wheel 272 to rotate through each linkage pawl 273, so that the rotation of the test rod 26 is not easy to drive the linkage motor 275 to rotate, so that the linkage motor 275 is not easy to interfere with the rotation of the test rod 26.

[0049] Reference Figure 2 and Figure 6 The test mechanism 2 also includes a plurality of test components 29, each of which is respectively arranged on both sides of the test rod 26 and corresponds to the driving worm gear 281 one by one. The test components 29 include a connecting rod 291, a rotating rod 292, a connecting spring 293, a temperature sensor 294 and a speed sensor 295. The connecting rod 291 is rotatably arranged on the test rod 26 and is coaxially fixedly connected to the driving worm gear 281. The rotating rod 292 is rotatably arranged on the test rod 26 and is located at one end of the connecting rod 291 away from the test rod 26. The rotating rod 292 is away from the connecting rod 29 A plurality of rotating blades are fixedly arranged at one end of the test rod 26, a connecting spring 293 is located between the rotating rod 292 and the connecting rod 291, one end of the connecting spring 293 is fixedly connected to the connecting rod 291, and the other end of the connecting spring 293 is fixedly connected to the rotating rod 292, a temperature sensor 294 and a speed sensor 295 are both fixedly arranged on the test rod 26 and are both electrically connected to the test instrument 22, the temperature sensor 294 is used to sense the temperature of the latex paint and transmit the detected data to the test instrument 22, and the speed sensor 295 is used to detect the rotation speed of the rotating rod 292.

[0050] When the viscosity of the latex paint needs to be tested, the temperature sensor 294 is started, and the temperature sensor 294 transmits the detected temperature of the latex paint to the testing instrument 22, driving the worm gear 281 to drive the connecting rod 291 to rotate, and the rotation of the connecting rod 291 drives the rotating rod 292 to rotate through the connecting spring 293, and the speed sensor 295 detects the rotation speed of the rotating rod 292 and transmits it to the testing instrument 22. The testing instrument 22 converts the rotation speed of each rotating rod 292 into a corresponding viscosity value, and then displays the viscosity value of the latex paint at different temperatures of each latex paint, thereby completing the test of the viscosity value of the latex paint at multiple temperatures, thereby making the test efficiency of the latex paint better.

[0051] When the test rod 26 rotates, the test rod 26 drives the connecting rod 291 to rotate circumferentially around the axis of the test rod 26. The rotation of the connecting rod 291 drives the connecting spring 293 to rotate circumferentially around the axis of the test rod 26. The rotation of the connecting spring 293 drives the rotating rod 292 to rotate circumferentially around the axis of the test rod 26, so that the rotating rod 292 stirs the latex paint, so that the test device does not need to add an additional stirring structure, which makes the manufacturing simpler and more convenient. At the same time, each adjacent test component 29 is respectively located on both sides of the test rod 26, so that when the rotating component 25 drives the test rod 26 to rotate, each rotating rod 292 stirs in multiple directions at the same time, and each rotating rod 292 has a better stirring effect on the latex paint.

[0052] The implementation principle of a latex paint viscosity testing device in the embodiment of the present application is as follows: when the viscosity of the latex paint needs to be tested, the latex paint is poured into the device container 13, the test cylinder 21 is driven, and the piston rod of the test cylinder 21 drives the test instrument 22 to move toward the device container 13 until all the test components 29 enter the device container 13, and the rotating component 25 drives the test rod 26 to rotate, thereby achieving stirring of the latex paint, and the heating module or the cooling module is started to heat the latex paint in the device container 13. When the latex paint in the device container 13 is heated or cooled, the latex paint in the device container 13 is heated or cooled. When the temperature at each height is different, each test component 29 performs viscosity tests on the latex paint at different heights, and then sends the multiple test signals to the test instrument 22. The test instrument 22 then displays the viscosity value and temperature value of each test component 29 corresponding to the latex paint at different temperatures, thereby completing the test of the viscosity value of the latex paint at multiple temperatures. This improves the problem that when it is necessary to test the viscosity of latex paint at multiple different temperatures, the latex paint needs to be repeatedly heated or cooled and then re-measured, which makes the measurement process more cumbersome and leads to poor test results.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
