Description

Technical Field

[0001] This invention relates to the field of viscosity testing technology, specifically to a high-temperature viscosity precision testing device for road marking paint. Background Technology

[0002] Road markings are markings on road surfaces that use lines, arrows, text, vertical markings, raised pavement markers, and delineators to convey traffic information such as guidance, restrictions, and warnings to road users. Hot-melt road marking paint has advantages such as fast drying, thick film, and long service life. During application, it needs to be heated to a certain temperature to melt the paint before being applied to the road surface. It has good durability and can withstand frequent vehicle traffic and abrasion. Testing the high-temperature viscosity of road marking paint is crucial for evaluating its application performance and quality.

[0003] In existing technologies, the high-temperature viscosity of road marking paint can be measured by capturing the dynamic behavior of the paint with a camera, and then extracting feature parameters (such as time, displacement, and shape changes) through image processing algorithms to indirectly calculate the viscosity. The camera captures the essential characteristics of the paint in real time during the stirring process, and the viscosity of the paint can be measured non-contactly through relevant algorithms. However, in existing technologies, the camera is fixed in a stationary position during detection. A stationary camera can only capture a local area of ​​the paint (such as the center or edge of the container), which may miss key rheological features during the stirring process (such as the shear layer at the blade tip, the vortex formation zone, or the boundary effect region), resulting in incomplete data for the detection of paint viscosity.

[0025] Working Principle: In operation, the operator first introduces the testing coating into the testing container 7 through the inlet pipe 4, then starts the motor 3. The motor 3 drives the rotating rod 83 to rotate, which in turn drives the bevel gear 4 817 to rotate. The bevel gear 4 817 drives the bevel gear 3 816 to rotate, which in turn drives the stirring blades 811 on the stirring rod 88 to rotate, facilitating the stirring of the coating by the stirring blades 811. Simultaneously, the rotating rod 83 drives the bevel gear 1 84 to rotate, which in turn drives the bevel gear 2 85 to rotate. Under the action of the control rod 86, gear 1 94, and gear ring 93, the detection camera 99 on the horizontal plate 95 can be rotated, increasing the viscosity detection range of the detection camera 99. While stirring the coating, the rotating rod 83 drives the cam 820 to rotate, which in turn drives the lifting ring 819 to move up and down repeatedly. The lifting ring 819 drives the abutment rod 818 to move. Under the action of the moving cover 813, the connecting rod 812 and the lifting block 810, the stirring blade 811 is controlled to move up and down repeatedly to increase the stirring effect. At the same time, the horizontal plate 95 drives the gear component 3 925 to revolve around the gear component 2 910. Since the gear component 3 925 is meshed with the gear component 2 910, the gear component 3 925 rotates on its own axis. The gear component 3 925 drives the control shaft 922 to rotate. Under the action of the bevel gear 5 923, bevel gear 6 924, rotating shaft 917, control block 918 and inclined plate 2 919, the connecting plate 914 is controlled to move up and down repeatedly. The connecting plate 914 drives the slider 2 913 to move. The slider 2 913 drives the inclined plate 1 915 to rotate. The inclined plate 1 915 drives the slider 1 97 to drive the detection camera 99 to move left and right repeatedly to further expand the detection range.
