Accurate testing device for high-temperature viscosity of road marking paint

Abstract

The utility model relates to an accurate high-temperature viscosity testing device for road marking paint, and effectively solves the problem that the marking paint is easily mixed insufficiently in the detection process due to the fact that the testing position of the conventional viscosity testing device is fixed relatively, so that the viscosity of the marking paint cannot be accurately measured in the detection process. The problem that the overall accuracy is not high due to the fact that the test error is large due to the fact that the detection position is single in the prior art is solved. According to the high-temperature viscosity accurate testing device for the road marking paint, through cooperative arrangement of the threaded rod and the adjusting seat, the adjusting seat can be driven to float up and down through rotation of the threaded rod, and then the viscometer can be driven to adjust the up-down position, so that the detection position of the viscometer on the paint is changed, and the detection accuracy of the device on the paint is improved; and when the stirring blades are driven to rotate through the transmission shaft, the coating in the storage tank can be fully mixed and stirred, so that the coating is fully mixed.

Technical Field

[0001] The utility model belongs to the technical field of viscosity testing, and particularly relates to a device for accurately testing the high-temperature viscosity of road marking paint. Background Technique

[0002] Road markings refer to the signs on the road surface that convey traffic information such as guidance, restriction, and warning to traffic participants with lines, arrows, words, elevation markings, raised road studs, and contour markers, etc. Hot-melt marking paint has the advantages of fast drying, thick coating film, and long service life. During construction, it needs to be heated to a certain temperature to melt and then coated on the road surface. It has good durability and can withstand the frequent rolling and wear of vehicles.

[0003] Testing the high-temperature viscosity of road marking paint is of great significance for evaluating the construction performance and quality of the paint. However, in existing viscosity testing devices, the testing position is often relatively fixed. As a result, during the detection process of the marking paint, the situation of insufficient mixing is likely to occur. Therefore, during the detection process, due to the single detection position, the testing error is relatively large, and thus the overall accuracy is not high. Content of the Utility Model

The device for accurately testing the high-temperature viscosity of road marking paint can fully stir and mix the paint inside the storage tank by driving the rapid rotation of the stirring blade through a transmission shaft, thereby reducing the measurement error. Under the rotation of the threaded rod, the adjusting seat can be driven to slide up and down, thereby driving the viscometer to float up and down. Therefore, the paint is detected at multiple positions, and thus the detection accuracy of the device is improved.

The inner side wall of the support frame is rotatably connected with a threaded rod. The outer surface of the threaded rod is threadedly connected with an adjusting seat.

[0006] Preferably, a pressure rod is threadedly inserted through the outer surface of the limit ring. One end of the pressure rod inserted into the limit ring abuts against the outer wall of the storage tank, so that the storage tank is firmly connected to the inner wall of the limit ring.

[0007] Preferably, a fixing base is detachably connected to the top of the sealing cover, and a protective shell is threadedly connected to the top of the fixing base.

[0008] Preferably, a first motor is fixedly installed on the top of the fixing base, and the output end of the first motor is clamped to the top of the transmission shaft.

[0009] Preferably, a clamping groove is formed on the outer wall of the fixing base, and a clamping block adapted to the clamping groove is formed on the top of the sealing cover.
