Description

Technical Field

[0001] This invention relates to the field of road marking paint testing technology, specifically to a sample preparation device and method for road marking paint quality testing. Background Technology

[0002] Road marking paint is a type of paint specifically used for road markings and signs. It is usually composed of resin, pigments, fillers, and additives. Its main function is to form clear and durable markings on the road to guide traffic flow and improve driving safety.

[0003] Before road markings are installed, paint samples need to undergo various tests, including whiteness testing, flowability testing, and abrasion resistance testing. For example, Chinese invention patent 202110734129.5 discloses an energy-saving and environmentally friendly tester for the abrasion resistance of road marking paint, aiming to provide a method for qualitative testing of paint abrasion resistance under different pressures or speeds, facilitating comparison of test results during the testing process. Chinese invention patent 202510907883.2 discloses a test device for the abrasion resistance of road marking paint, which can switch between paint application and scraping functions. During this process, the generated gas dries the applied paint and simultaneously blows the scraped paint onto a testing scale, automatically completing the abrasion resistance test. However, none of the above invention patents involve the preparation of paint samples for whiteness testing, flowability testing, or abrasion resistance testing.

[0004] Currently, the preparation of paint samples is mainly done manually. Eight to nine materials are manually weighed and mixed before being placed in the container and heated. During heating, continuous stirring and temperature monitoring with a thermometer are required. Abrasion resistance testing necessitates manually drilling holes in the center of the sample, resulting in low automation. Therefore, it is necessary to design a device and method for preparing road marking paint quality testing samples. Summary of the Invention

[0058] Example 2: like Figure 1 As shown, this embodiment relates to a method for preparing road marking paint quality test samples, which is implemented based on the preparation device described in Embodiment 1. The method includes the following steps.

[0059] Step 1: The integrated controller 4 controls the X-direction motion drive motor 1191 of the portal frame, which, through the gear and rack drive system 119, drives the portal frame 13 to move in the opposite direction of the X-axis, away from the second support platform 121. The manually weighed and prepared materials are placed into the paint loading container 118. The integrated controller 4 then controls the X-direction motion drive motor 1191 of the portal frame, which, through the gear and rack drive system 119, drives the portal frame 13 to move in the positive direction of the X-axis, closer to the second support platform 121, so that the axis of the paint loading container 118 and the axis of the electric furnace 120 are aligned with each other relative to the X-axis.

[0060] Step 2: The integrated controller 4 controls the second lead screw and nut pair drive motor 15, which in turn drives the paint loading container via the matching nut 17 of the second lead screw. Z The directional motion drive system 19 moves along the Y-axis and approaches the second support platform 121, so that the axis of the paint loading container 118 and the axis of the electric furnace 120 are in the same position relative to the Y-axis.

[0061] Step 3: Integrated controller 4 controls the paint loading container. Z The lead screw and nut pair drive motor 311 of the directional motion drive system 19 drives the second motor mounting platform 116 to move along the Z-axis direction, which is driven by the nut 317 matched with the lead screw, so that the paint loading container 118 is placed in the electric furnace 120 for heating.

[0062] Step 4: The integrated controller 4 controls the first lead screw and nut pair drive motor 14, which in turn drives the coating mixing and temperature measurement system via the first lead screw and matching nut 110. Z The directional motion drive system 111 moves along the Y-axis and approaches the second support platform 121, so that the axis of the stirrer 115 and the axis of the electric furnace 120 are in the same position relative to the Y-axis.

[0063] Step 5: Integrated controller 4 controls the coating mixing and temperature measurement system. Z The lead screw and nut drive motor 311 of the directional motion drive system 111 drives the first motor mounting platform 112 to move in the opposite direction of the Z-axis via the nut 317 matched with the lead screw. This moves the agitator 115 closer to the paint loading container 118, agitating the material during the heating process, while simultaneously monitoring the material temperature via a non-contact temperature sensor 113. When the material temperature reaches the desired value, the integrated controller 4 controls the paint agitation and temperature measurement system. Z The lead screw and nut drive motor 311 of the directional motion drive system 111 drives the first motor mounting platform 112 to move along the positive Z-axis direction via the nut 317 that matches the lead screw, so that the agitator 115 moves away from the paint loading container 118. This controls the first lead screw and nut drive motor 14, which in turn drives the paint stirring and temperature measuring system via the nut 110 that matches the first lead screw. Z The directional motion drive system 111 moves along the Y-axis away from the second support platform 121, so that the stirrer 115 is away from the electric furnace 120.

[0064] Step 6: Integrated controller 4 controls the paint loading container. Z The lead screw and nut drive motor 311 of the directional motion drive system 19 drives the second motor mounting platform 116 to move along the Z-axis direction via the nut 317 that matches the lead screw. This moves the paint loading container 118 away from the electric furnace 120, and the Z-direction position of the paint loading container 118 is higher than the Z-direction position of the third mold plate 214 of the road marking paint detection sample preparation device 2. The integrated controller 4 controls the X-direction motion drive motor 1191 of the portal frame, which, through the gear and rack drive system 119, drives the portal frame 13 to move in the positive X-direction direction, closer to the road marking paint detection sample preparation device 2, facilitating the pouring of material from the paint loading container 118 into the third mold plate 214.

[0065] Step 7: The paint loading container 118 approaches the third mold plate 214. Simultaneously, the integrated controller 4 controls the Z-direction motion drive system 232 of the third sample making device to drive the second mold plate 213, and the Z-direction motion drive system 234 of the second sample making device to drive the first mold plate 212 to approach the third mold plate 214. The second mold plate 213 and the first mold plate 212 maintain a minimum distance. The column 2121 of the first mold plate 212 passes through the movable bottom plate of the sample making slot and pushes out the boss 2131, and inserts into the column penetration hole 2146 of the movable bottom plate 2145 of the wear resistance test sample making slot in the third mold plate 214. To prevent the movable bottom plate 2145 of the wear resistance test sample making slot from moving when the column 2121 is inserted, the Z-direction motion drive system 233 of the first sample making device drives the fourth mold plate 215 to approach the third mold plate 214. The fourth mold plate sample grinding boss 2154 of the fourth mold plate 215 is in contact with the movable bottom plate 2145 of the wear resistance test sample making slot. When the column 2121 is inserted into the movable base plate 2145 of the wear-resistant test sample making slot, the Z-direction motion drive system 233 of the first sample making device drives the fourth mold plate 215 away from the third mold plate 214.

[0066] Step 8: The integrated controller 4 controls the paint loading container to rotate, driving the paint loading container 118 to rotate. At the same time, the integrated controller 4 controls the mold disk to rotate, driving the third mold disk 214 to rotate via the gear 23, and pouring the material into the flowability test sample preparation tank 2141, the whiteness test sample preparation tank 2143, and the abrasion resistance test sample preparation tank 2147.

[0067] Step 9: The paint loading container 118 moves away from the third mold plate 214. The Z-direction motion drive system 233 of the first sample making device drives the fourth mold plate 215 closer to the third mold plate 214. The fourth mold plate sample grinding boss 2154 of the fourth mold plate 215 moves closer to the whiteness test sample making tank 2143 and the wear resistance test sample making tank 2147, compacting the material. After the material cools and solidifies, the Z-direction motion drive system 234 of the second sample making device drives the first mold plate 212 away from the third mold plate 214, and the column 2121 is pulled out from the movable bottom plate 2145 of the wear resistance test sample making tank. The Z-direction motion drive system 232 of the third sample preparation device drives the second mold disk 213 to approach the third mold disk 214. The movable bottom plate of the sample preparation tank pushes the movable bottom plates 2142, 2144, and 2145 of the flowability test sample preparation tank, whiteness test sample preparation tank, and abrasion resistance test sample preparation tank upwards until their upper surfaces are flush with the upper surfaces of the corresponding flowability test sample preparation tank 2141, whiteness test sample preparation tank 2143, and abrasion resistance test sample preparation tank 2147. The fork rotation drive motor 24 drives the fork 27 to rotate and push the completed paint sample into the paint sample collection tray 26.

[0068] Step 10: Return all equipment to its initial position and prepare for the production of the next batch of paint samples.

10. A method for preparing quality test samples of road marking paint, implemented based on the preparation apparatus described in any one of claims 1-8, characterized in that, The method includes the following steps: Step 1: The integrated controller controls the drive component of the X-direction motion system, causing the gantry frame to move in the opposite direction of the X-axis, away from the electric furnace; the manually weighed and configured materials are placed into the paint loading container of the Z-direction motion drive system of the paint loading container, and the drive component drives the gantry frame to move in the positive direction of the X-axis, closer to the electric furnace. Step 2: Control one of the Y-direction motion systems to drive the paint loading container. Z The directional motion drive system moves along the Y-axis, approaching the electric furnace; Step 3: Control the paint loading container Z The directional motion drive system moves the paint loading container along the Y-axis and places it into the electric furnace for heating; Step 4: Control another Y-direction motion system to drive the coating stirring and temperature measuring system. Z The directional motion drive system moves along the Y-axis, approaches the electric furnace, stirs the material, and monitors the material temperature; Step 5: When the material temperature reaches the desired value, control the coating stirring and temperature measurement system. Z The directional motion drive system moves it along the positive Z-axis, away from the electric furnace; Step 6: Control the paint loading container Z The directional motion drive system drives it to move along the Z-axis, moving the paint loading container away from the electric furnace, and the Z-axis position of the paint loading container is higher than the Z-axis position of the third mold plate of the road marking paint detection sample preparation device; the X-axis motion control system drives the portal frame to move in the positive X-axis direction, closer to the road marking paint detection sample preparation device, so that the material in the paint loading container can be poured into the third mold plate. Step 7: The paint loading container approaches the third mold plate; simultaneously, the road marking paint testing sample making device is controlled to drive the second mold plate and the first mold plate to approach the third mold plate, the column of the first mold plate passes through the second mold plate and inserts into the third mold plate, and the fourth mold plate is driven to approach the third mold plate; after the column is inserted into the third mold plate, the fourth mold plate is driven to move away from the third mold plate. Step 8: Control the road marking paint dissolving device to drive the paint loading container to rotate, and at the same time control the third mold plate to rotate, pouring the material into the third mold plate; Step 9: Control the paint loading container away from the third mold plate; drive the fourth mold plate closer to the third mold plate to compact the material; after the material cools and solidifies, drive the first mold plate away from the third mold plate, and the column is pulled out from the third mold plate; drive the second mold plate closer to the third mold plate and move upward to push out the paint sample; the fork rotates and the drive motor drives the fork to rotate to push the completed paint sample into the paint sample recycling tray; the paint sample production is completed.
