Description

Technical Field

[0001] This invention relates to the field of pretreatment equipment technology, and in particular to a substrate interface-enhanced coating pretreatment device. Background Technology

[0002] In the field of high-temperature protection, the innovative application of thermally responsive protective material systems is driving technological innovation in the industry. The existing "graded thermally responsive fireproof and heat-insulating coating" achieves a breakthrough in gradient thermal barrier and interface stability in ultra-high temperature environments above 1300℃ through a three-layer synergistic mechanism of micro-nano porous thermal buffer layer, amorphous-crystalline composite ceramic conversion layer and radiation heat reflection functional layer. Its performance, such as second-level thermal response triggering, low toxicity pyrolysis products and high interface adhesion, is significantly better than traditional single thermal protection modes.

[0003] However, in coating applications on building substrates, the pretreatment of the oxide layer on the substrate surface has become a key bottleneck restricting coating performance. Since the oxide adhering to the substrate surface is prone to peeling due to direct contact with the coating, existing processes generally use manual grinding to remove the oxide layer. However, this method has significant drawbacks: firstly, manual operation makes it difficult to ensure the flatness of the ground surface, leading to local voids or stress concentrations at the coating-substrate interface, directly affecting coating adhesion and the uniformity of thermal protection; secondly, manual grinding is inefficient and cannot meet the needs of large-scale construction, and the dust generated during grinding poses a health hazard and increases the labor intensity of construction workers, problems that urgently need to be addressed. Therefore, this invention proposes a substrate interface-enhanced coating pretreatment device. Summary of the Invention

[0039] Example

[0040] like Figures 1 to 3As shown, the present invention proposes a substrate interface-enhanced coating pretreatment device, including a mounting plate 1 and a grinding wheel 2 disposed on one side of the mounting plate 1. A connecting plate 21 is connected to the side of the grinding wheel 2 away from the substrate. The grinding wheel 2 is connected to the side of the connecting plate 21 via a quick-release design, which is prior art and will not be described in detail here. Alternatively, the grinding wheel 2 can be replaced with a wire brush head, also mounted on the side of the connecting plate 21. By reducing the rotation speed, the grinding wheel 2 scratches the substrate surface, thereby increasing the contact area between the coating and the substrate.

[0041] Furthermore, the aforementioned pretreatment device includes a grinding mechanism 3 mounted on the side of the mounting plate 1. The grinding mechanism 3 is used to drive the grinding wheel 2 to rotate for grinding. The grinding mechanism 3 includes a first servo motor 31 fixedly connected to one side of the mounting plate 1. The output end of the first servo motor 31 is fixedly connected to a rotating cylinder 32. After the first servo motor 31 is started, it drives the rotating cylinder 32 to rotate. The outer ring of the rotating cylinder 32 is rotatably connected to multiple sets of positioning seats 34 through bearings. The positioning seats 34 are fixedly connected to the side of the mounting plate 1, so that the rotating cylinder 32 maintains its original position relative to the mounting plate 1. A drive rod 33 is slidably connected in the rotating cylinder 32. The end of the drive rod 33 away from the first servo motor 31 is fixedly connected to the connecting plate 21. The drive rod 33 is a polygonal prism. Through the corners of the quadrangular prism, the drive rod 33 is driven to rotate synchronously when the rotating cylinder 32 rotates. At the same time, the drive rod 33 can slide in the rotating cylinder 32.

[0042] Furthermore, the aforementioned pretreatment device also includes a pressure sensing component 4 mounted on the grinding mechanism 3. The pressure sensing component 4 is used to monitor the pressure of the grinding wheel 2 on the substrate in real time. The pressure sensing component 4 includes a connecting disc 41 fixedly connected to the outer ring of the drive rod 33. The connecting disc 41 is positioned between the rotating cylinder 32 and the connecting plate 21. When the drive rod 33 rotates, it drives the connecting disc 41 to rotate synchronously. Simultaneously, when the drive rod 33 slides within the rotating cylinder 32, the connecting disc 41 moves. A synchronous disc 42 is rotatably connected to the outer ring of the connecting disc 41 via bearings. Through the arrangement of the connecting disc 41 and bearings, the rotation of the drive rod 33 is not hindered when the synchronous disc 42 is restricted from rotating. Simultaneously, the drive rod 33 and the synchronous disc 42 rotate synchronously. Side plates 43 are fixedly connected to both sides of the synchronous disc 42. When the drive rod 33 moves, it drives the side plates 43 to move synchronously. Two sets of side plates 43 are fixedly connected to movable rods 44 on the side away from the connecting plate 21. Adjusting plates 45 are slidably connected to the two sets of movable rods 44. Both sets of adjusting plates 45 are fixedly connected to the side of the mounting plate 1. The limiting effect of the movable rods 44 and the adjusting plates 45 prevents the synchronous disc 42 from rotating. The ends of the two sets of movable rods 44 away from the side plates 43 are fixedly connected to limiting plates 46. The limiting plates 46 prevent the movable rods 44 from detaching from the adjusting plates 45. Springs 47 are respectively sleeved on the outer ring of the two sets of movable rods 44. The springs 47 are located between the side plates 43 and the adjusting plates 45. Through the elastic force of the springs 47, the springs 47 are compressed and then released, making the grinding wheel 2 stick tightly to the substrate. Two sets of moving rods 44 are slidably connected to detection plates 48. The detection plates 48 are located between the adjusting plate 45 and the spring 47. Pressure sensors 49 are installed in the two sets of adjusting plates 45 respectively. The detection end of the pressure sensor 49 is fixedly connected to the detection plate 48. The pressure sensor 49 detects the elastic force at one end of the spring 47 through the detection plate 48, thereby knowing the pressure of the grinding wheel 2 on the substrate.

[0043] Protective covers can be installed at the positions of the synchronous disc 42 and the side plate 43 to isolate the oxide layer powder and base powder that have been polished off, and to prevent impurities from entering the sliding positions of the moving rod 44 and the adjusting plate 45, as well as the sliding positions of the rotating cylinder 32 and the drive rod 33, so as to ensure smooth movement.

[0044] Specifically, the above-mentioned preprocessing device includes a pressure regulating mechanism 5 installed on the side of the mounting plate 1 away from the grinding mechanism 3. The pressure regulating mechanism 5 is used to keep the pressure of the grinding wheel 2 on the substrate constant. The pressure regulating mechanism 5 includes a first push rod motor 51 fixedly connected to the side of the mounting plate 1 away from the first servo motor 31. The output end of the first push rod motor 51 is fixedly connected with a moving block 52. A positioning plate 6 is installed on the side of the moving block 52 away from the mounting plate 1. After the positioning plate 6 is fixed, when the first push rod motor 51 extends, it带动 the mounting plate 1 to move through the reaction force. A plurality of sliding blocks 53 are fixedly connected to the side of the positioning plate 6 close to the mounting plate 1. A slide rail 54 is respectively slidably connected to the plurality of sliding blocks 53. The plurality of slide rails 54 are all fixedly connected to the mounting plate 1. Through the limiting effect of the sliding block 53 and the slide rail 54, the movement of the mounting plate 1 is stable.

[0045] ' In this embodiment, the above-mentioned preprocessing device includes a lateral driving component 7 for driving the grinding wheel 2 to perform lateral grinding on the substrate. The lateral driving component 7 includes a driving block 71 fixedly connected to the side of the positioning plate 6 away from the mounting plate 1. When the driving block 71 moves, it带动 the positioning plate 6 to move synchronously. A first threaded rod 72 is threadedly connected to the driving block 71. When the first threaded rod 72 rotates, it带动 the driving block 71 to move along the length direction of the first threaded rod 72. One end of the first threaded rod 72 is rotatably connected to a mounting frame 73. The mounting frame 73 is arranged in a "匚" shape. A second servo motor 74 is installed in the mounting frame 73. The output end of the second servo motor 74 penetrates through the mounting frame 73 and is fixedly connected to the first threaded rod 72. After the second servo motor 74 is started, it带动 the first threaded rod 72 to rotate. A first limiting rod 75 is slidably connected to the driving block 71. The first limiting rod 75 is arranged parallel to the first threaded rod 72. Through the limiting effect of the first limiting rod 75 when the driving block 71 moves, the movement of the driving block 71 is stable.

[0046] Furthermore, the aforementioned pretreatment device also includes a vertical drive mechanism 8 for driving the grinding wheel 2 to perform vertical grinding on the substrate. The vertical drive mechanism 8 includes a base plate 81 disposed below the grinding wheel 2. Two sets of fixing frames 82 are fixedly connected to the top of the base plate 81. Vertical plates 83 are fixedly connected to the sides of the two sets of fixing frames 82 away from the base plate 81, and the positions of the fixing frames 82 and the vertical plates 83 are fixed. The two sets of vertical plates 83 are symmetrically arranged on both sides of the grinding wheel 2. Top plates 84 are fixedly connected to the top of the sides of the two sets of vertical plates 83 away from each other. A second limiting rod 85 is fixedly connected between one set of top plates 84 and the base plate 81, and the position of the second limiting rod 85 is fixed. A sliding sleeve 86 is slidably connected to the second limiting rod 85. One end of the first limiting rod 75 and the mounting frame 73 are both fixedly connected to the sliding sleeve 86. The sliding sleeve 86 cooperates with the second limiting rod 85 to limit movement when the horizontal drive assembly 7 moves. Another set of top plates 84 and bottom plates 81 are rotatably connected by a second threaded rod 87, which rotates while remaining in its original position. A threaded sleeve 88 is threadedly connected to the second threaded rod 87, and when the second threaded rod 87 rotates, it drives the threaded sleeve 88 to move along the length of the second threaded rod 87. The other end of the first limiting rod 75 is fixedly connected to the threaded sleeve 88, and the end of the first threaded rod 72 away from the mounting frame 73 is rotatably connected to the threaded sleeve 88. When the threaded sleeve 88 moves, it drives the transverse drive assembly 7 to move, thereby changing the grinding height of the grinding wheel 2. A third servo motor 89 is installed on the top of the bottom plate 81. The output end of the third servo motor 89 is fixedly connected to a first bevel gear 810. A second bevel gear 811 is provided on one side of the first bevel gear 810 and meshes with it. After the third servo motor 89 is started, it drives the second bevel gear 811 to rotate through the first bevel gear 810. The second bevel gear 811 is fixedly connected to the outer ring of the second threaded rod 87, and when the second bevel gear 811 rotates, it drives the second threaded rod 87 to rotate synchronously.

[0047] Furthermore, the aforementioned pretreatment device also includes a calibration component 9 for monitoring the adhesion between the grinding wheel 2 and the substrate. The calibration component 9 includes two sets of fixing plates 91 mounted on the side of the base plate 81. A second push rod motor 92 is mounted on the top of each of the two sets of fixing plates 91. A first displacement meter 93 is fixedly connected to the output end of the second push rod motor 92. After starting, the second push rod motor 92 drives the detection end of the first displacement meter 93 to contact the substrate. A fixing frame 94 is mounted on opposite sides of each of the two sets of fixing plates 83. A third push rod motor 95 is mounted in each of the two sets of fixing frames 94. A second displacement meter 96 is fixedly connected to the output end of the third push rod motor 95. After starting, the third push rod motor 95 drives the detection end of the second displacement meter 96 to contact the substrate. The position and orientation of the base plate 81 are adjusted based on the data from the two sets of first displacement meters 93 and second displacement meters 96 to ensure a tight fit between the grinding wheel 2 and the substrate.

[0048] Finally, the aforementioned pretreatment device also includes a control display screen. The first servo motor 31, pressure sensor 49, first push rod motor 51, second servo motor 74, third servo motor 89, second push rod motor 92, first displacement meter 93, third push rod motor 95, and second displacement meter 96 are all electrically connected to the control display screen. After the grinding wheel 2 becomes thinner after grinding, the distance between the two ends of the spring 47 increases, thereby reducing the pressure exerted by the spring 47 on the grinding wheel 2 on the substrate. The first push rod motor 51 is activated, and through the reaction force, it drives the mounting plate 1 closer to the substrate and compresses the spring 47, thus ensuring that the pressure of the grinding wheel 2 on the substrate remains constant. At the same time, the control display screen records the changes in the average value of the two sets of pressure sensors 49 to know the changes in the pressure of the grinding wheel 2 on the substrate. During the first grinding, due to the unevenness of the substrate surface, the protruding positions experience larger pressure changes. Therefore, during the second grinding, the first push rod motor 51 is activated at the protruding positions, and through the reaction force, it drives the mounting plate 1 closer to the substrate, thereby compressing the spring 47 and increasing the elasticity, so that the substrate surface is ground smooth.

[0049] In this embodiment, the average value of the two sets of pressure sensors 49 is the pressure and friction of the grinding wheel 2 on the substrate. Under the condition that the friction remains unchanged, the change of the pressure of the grinding wheel 2 on the substrate can be effectively monitored.

[0050] In this embodiment, the device is first placed next to the substrate, so that the grinding wheel 2 contacts the substrate and simultaneously compresses the two sets of springs 47. The two sets of second push rod motors 92 and two sets of third push rod motors 95 are activated by controlling the display screen, which drives the first displacement meter 93 and the second displacement meter 96 to contact the substrate. By observing the four sets of data displayed on the control display screen, the position and tilt angle of the base plate 81 are adjusted so that the data of the two sets of first displacement meters 93 and the two sets of second displacement meters 96 are consistent. At this time, the grinding surface of the grinding wheel 2 is in close contact with the substrate.

[0051] During polishing, the first servo motor 31 starts, driving the rotating cylinder 32 to rotate, which in turn drives the connecting plate 21 via the drive rod 33, thereby driving the polishing wheel 2 to rotate. The second servo motor 74 starts, driving the first threaded rod 72 to rotate. As the threaded rod 72 rotates, it drives the drive block 71 to move laterally. Simultaneously, the drive block 71 moves smoothly under the limiting action of the first limit rod 75, driving the polishing wheel 2 to perform lateral polishing. After lateral polishing at the same height is completed, the third servo motor 89 starts, driving the first bevel gear 810 to rotate, which in turn drives the second threaded rod 87 to rotate via the second bevel gear 811, causing the threaded sleeve 88 to move vertically. This allows the drive block 71 and the first limit rod 75 to move smoothly under the limiting action of the second limit rod 85 and the sliding sleeve 86, thereby changing the height of the polishing wheel 2. Through the cooperation of the lateral drive assembly 7 and the vertical drive mechanism 8, the substrate is thoroughly polished.

[0052] During the polishing process, after the polishing wheel 2 becomes thinner, the spring 47 releases its elastic force, thereby reducing the pressure of the polishing wheel 2 on the substrate. The elastic force of the spring 47 sensed by the two pressure sensors 49 also decreases. At this time, the first push rod motor 51 is activated. The reaction force of the first push rod motor 51 drives the mounting plate 1 closer to the substrate, and simultaneously the adjusting plate 45 moves closer to the substrate, causing the spring 47 to be compressed. Simultaneously, the control display takes the average value of the two pressure sensors 49 as the pressure of the polishing wheel 2 on the substrate, and coordinates with the adjustment of the first push rod motor 51 to ensure that the pressure of the polishing wheel 2 on the substrate remains constant.

[0053] During the first full grinding of the substrate, due to the unevenness of the substrate surface, a large pressure change occurs at the protruding positions, which is sensed by the pressure sensor 49. Therefore, during the second grinding, the first push rod motor 51 is activated at the protruding position, compressing the spring 47 to increase its elasticity, thereby increasing the pressure of the grinding wheel 2 on the substrate at the protruding position, resulting in a smooth substrate surface.

[0054] After grinding, the grinding wheel 2 is replaced with a wire brush, which is driven by the grinding mechanism 3 and works with the horizontal drive component 7 and the vertical drive mechanism 8 to scrape away scratches on the surface of the substrate after grinding, so as to increase the contact area between the coating and the substrate and ensure the strength of the coating.

[0055] The above specific embodiments are merely optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
