Description

TECHNICAL FIELD

[0001] The utility model relates to detection technical field especially relates to a hot melt marking paint viscosity detection device. BACKGROUND

[0002] In the field of road marking construction, hot melt type road marking paint is widely used due to its good wear resistance, weather resistance and night reflection performance. However, the viscosity characteristics of hot melt marking paint have a crucial influence on its construction quality. Too high viscosity may cause the paint to be difficult to uniformly apply during construction, resulting in poor leveling, uneven surface and other problems; too low viscosity may cause the paint to flow during application, affecting the thickness and shape accuracy of the marking, and even causing the marking to wear out prematurely during use.

[0003] Currently, for the detection of hot melt marking paint viscosity, traditional methods often have the disadvantages of complicated operation, low detection accuracy and difficulty in accurately controlling the detection temperature. For example, some simple viscosity detection methods may not be able to simulate the temperature environment of the paint during actual construction and use, resulting in a large deviation between the detection results and the actual use. Moreover, unstable temperature control of the paint sample during detection will also affect the accurate measurement of viscosity. Therefore, it is of great practical significance to develop a hot melt marking paint viscosity detection device that can accurately control the detection temperature, is simple to operate and has high detection accuracy.

[0041] Please see Figures 1 to 4 This application provides a device for detecting the viscosity of hot-melt road marking paint, including a base 1, a lifting part 2, a viscosity detection part 3, a constant temperature system 4, and a sample container 5 (specifically, it can be made of a high-temperature resistant metal material). The base 1 has a flat plate structure; the lifting part 2 is disposed on the base 1, and the lifting direction of the lifting part 2 is perpendicular to the base 1; the viscosity detection part 3 is disposed on the lifting part 2; the constant temperature system 4 is disposed on the base 1, and the detection end of the viscosity detection part 3 extends into the constant temperature system 4, and the viscosity detection part 3 and the constant temperature system 4 are in sliding fit; the sample container 5 is located inside the constant temperature system 4 and below the viscosity detection part 3, and the sample container 5 contains the hot-melt road marking paint sample to be tested.

[0042] This invention is used to test the viscosity of hot-melt road marking paint. During testing, the sample container 5 containing the hot-melt marking sample to be tested is placed into the constant temperature system 4. The viscosity detection unit 3 is lowered by the lifting part 2, so that the detection end of the viscosity detection unit 3 extends downward into the interior of the hot-melt marking sample (e.g., ...). Figures 3-4 As shown in the diagram, the hot-melt marking sample to be tested is then heated to the testing temperature by the constant temperature system 4 and kept at that temperature for a certain period of time. Finally, the viscosity detection unit 3 is turned on to detect the viscosity of the hot-melt marking sample, and the viscosity result is obtained. Furthermore, the testing temperature of the hot-melt marking sample can be changed by the constant temperature system 4 to determine the viscosity value of the hot-melt marking sample at different temperatures, so as to plot the viscosity-temperature curve.

[0043] In one embodiment, the lifting unit 2 includes a column 21, a lifting slide 22, a lead screw 23, and a first rotary power device 24. The column 21 is vertically mounted on the base 1 and has a groove perpendicular to the base 1. The lifting slide 22 is slidably fitted onto the groove of the column 21, and the viscosity detection unit 3 is fixed to the lifting slide 22. The lead screw 23 is rotatably mounted on the column 21 and is perpendicular to the base 1; the lifting slide 22 is threaded onto the lead screw 23. The first rotary power device 24 is mounted on the column 21, and its power output shaft is connected to the lead screw 23.

[0044] When it is needed to lower the viscosity detection part 3 so that the spindle-shaped cone 321 extends into the hot melt marking sample in the sample cylinder 5, only the first rotary power device 24 (specifically, a motor) is started to rotate, the lead screw 23 is driven to rotate by the first rotary power device 24, and then the lifting slide 22 is slid downward along the sliding groove, so that the viscosity detection part 3 is lowered until the spindle-shaped cone 321 is lowered into place. When the viscosity measurement is completed, the first rotary power device 24 can be reversed to pull out the spindle-shaped cone 321 from the sample cylinder 5, so as to take out the sample cylinder 5 in the constant temperature system 4.

[0045] In one embodiment, the viscosity detection part 3 comprises a display controller 31, a rotating rod 32, and a torque sensor 33. The display controller 31 is arranged on the lifting slide 22, and a reading display screen 311 and control buttons 312 are arranged on the surface of the display controller 31. A second rotary power device is arranged in the display controller 31, and the control buttons 312 are electrically connected with the second rotary power device and the first rotary power device 24, and the control buttons 312 control the operation of the second rotary power device and the first rotary power device 24. The top of the rotating rod 32 is electrically connected with the power output shaft of the second rotary power device, the rotating rod 32 is slidingly fitted on the constant temperature system 4, and the lower segment of the rotating rod 32 extends into the constant temperature system 4. The bottom of the rotating rod 32 is provided with the spindle-shaped cone 321, and the rotating shaft direction of the rotating rod 32 is perpendicular to the base 1. The torque sensor 33 is arranged on the rotating rod 32, and the torque sensor 33 is electrically connected with the reading display screen 311.

[0046] Specifically, the control buttons 312 include a lifting button for controlling the operation of the first rotary power device 24, and a test button for controlling the rotation speed and start-stop of the second rotary power device. During testing, the first rotary power device 24 is controlled to work by pressing the lifting button, so that the rotating rod 32 and the spindle-shaped cone 321 at the bottom thereof extend into the hot melt marking sample in the sample cylinder 5. Then, the second rotary power device is controlled to rotate and control the rotation speed by the test button, the rotating rod 32 and the spindle-shaped cone 321 thereon are driven to rotate by the second rotary power device. When the spindle-shaped cone 321 rotates in the hot melt marking sample, it is resisted by the hot melt marking sample (the resistance increases as the viscosity of the hot melt marking sample increases). Therefore, when the spindle-shaped cone 321 rotates in the hot melt marking sample at a fixed speed, the resistance is proportional to the viscosity of the hot melt marking sample. The resistance acting on the rotating rod 32 is a torque resistance opposite to the rotating direction of the rotating rod 32, and then the torque resistance of the rotating rod 32 is detected by the torque sensor 33, so that the viscosity value of the hot melt marking sample can be accurately measured.

[0047] Optionally, the torque sensor 33 can be a strain gauge torque sensor, which is attached to the rotating shaft 32 (when the rotating shaft 32 is subjected to a torque resistance, the torque resistance will cause the rotating shaft 32 to deform slightly, and then the strain gauge torque sensor on the rotating shaft 32 will deform, causing the resistance value of the strain gauge torque sensor to change, and then the size of the torque resistance can be measured), so that the size of the torque force acting on the rotating shaft 32 can be monitored in real time. The strain gauge torque sensor 33 is electrically connected to the readout display screen 311, and a processor is connected therebetween. The processor converts the torque force value measured by the strain gauge torque sensor 33 into a viscosity value, which is displayed on the readout display screen 311, so that the detection personnel can intuitively know the viscosity value through the readout display screen 311.

[0048] As shown in Figure 4 In one embodiment, the constant temperature system 4 includes a constant temperature box 41, a heating plate 42, a temperature sensor 43, and a constant temperature controller 44. The constant temperature box 41 has a through hole at the top, the rotating shaft 32 is slidingly fitted in the through hole of the constant temperature box 41, and the sample cylinder 5 is located in the constant temperature box 41. The heating plate 42 is built into the inner wall of the constant temperature box 41. The temperature sensor 43 is arranged in the constant temperature box 41. The constant temperature controller 44 is electrically connected to the heating plate 42 and the temperature sensor 43. The detection personnel can control the constant temperature controller 44 to keep the temperature in the constant temperature box 41 constant. The constant temperature controller 44 controls the output power of the heating plate 42 according to the comparison between the temperature measured by the temperature sensor 43 and the set temperature value, so that the temperature in the constant temperature box 41 is maintained at the set value, thereby ensuring the accuracy of the viscosity determination.

[0049] In one embodiment, the constant temperature controller 44 is provided with a temperature display screen 441 and a temperature setting button 442. The temperature display screen 441 is electrically connected to the temperature sensor 43 and displays the temperature value in the constant temperature box 41 (i.e. the temperature value of the hot melt reference line sample in the sample cylinder 5) in real time. The temperature setting button 442 can be used to input and adjust the set temperature, so that the viscosity of the hot melt reference line sample can be determined under different temperature conditions.

[0050] In one embodiment, the constant temperature box 41 is provided with a hinged door 411 on one side. The hinged door 411 is hinged to the constant temperature box 41. The hinged door 411 is provided to facilitate the taking out and putting into of the sample cylinder 5 from / to the constant temperature box 41, and to maintain good airtight and heat insulation performance of the constant temperature box 41.

[0051] Optionally, a heat insulation layer can be provided outside the constant temperature box 41, which is made of heat preservation materials (such as heat preservation cotton, etc.), so as to improve the heat preservation performance of the constant temperature box 41 and reduce energy consumption.

[0052] In one embodiment, the base 1 is provided with a horizontal bubble 11. By the horizontal bubble 11, the base 1 can be adjusted to be horizontal, so that the spindle-shaped cone 321 is perpendicular to the surface of the hot melt marking sample, and the measurement error is eliminated.

[0053] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
