Description

Technical Field

[0001] The present invention relates to the technical field of pretreatment devices, and in particular, to a substrate interface enhanced coating pretreatment device. Background Art

[0002] In the field of high-temperature protection, the innovative application of thermal response protection material systems is driving the technological innovation of the industry. The existing "hierarchical thermal response fireproof and heat-insulating coating" has achieved a breakthrough in gradient thermal barrier and interface stability in an ultra-high temperature environment above 1300°C through the three-layer collaborative mechanism of a micro-nano porous thermal buffer layer, an amorphous-crystalline composite ceramic conversion layer, and a radiative heat reflection functional layer. Its performance such as second-level thermal response triggering, low-toxicity pyrolysis products, and high interface adhesion is significantly superior to traditional single thermal protection modes.

[0003] However, in the coating application scenario of building substrates, the pretreatment problem of the substrate surface oxide layer has become a key bottleneck restricting the coating performance. Since the oxide attached to the substrate surface is in direct contact with the coating, it is easy for the coating to peel off due to the shedding of the oxide itself. The existing process generally uses manual grinding to remove the oxide layer, but this method has significant defects: on the one hand, it is difficult to ensure the flatness of the grinding plane during manual operation, resulting in local voids or stress concentration at the interface between the coating and the substrate, directly affecting the coating adhesion and the uniformity of thermal protection; on the other hand, the manual grinding efficiency is low, unable to meet the large-scale construction requirements, and the dust generated during the grinding process also poses a threat to the health of construction workers and the labor intensity problem needs to be solved urgently.

[0039] Embodiment

[0040] As Figures 1 to 3As shown in the figure, a substrate interface enhancement type coating pretreatment device proposed by the present invention includes a mounting plate 1, and further includes 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 through a quick-release design. This is the prior art and will not be elaborated here. At the same time, the grinding wheel 2 can also be replaced with a wire brush head, which is also installed on the side of the connecting plate 21. By reducing the rotation speed, the grinding wheel 2 scratches the surface of the substrate, facilitating the improvement of the contact area between the coating and the substrate.

[0041] Furthermore, the above pretreatment device includes a grinding mechanism 3 installed 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. A plurality of positioning seats 34 are rotatably connected to the outer circle of the rotating cylinder 32 through bearings. The positioning seats 34 are fixedly connected to the side of the mounting plate 1, so that the rotating cylinder 32 rotates in place relative to the mounting plate 1. A driving rod 33 is slidably connected in the rotating cylinder 32. One end of the driving rod 33 away from the first servo motor 31 is fixedly connected to the connecting plate 21. The driving rod 33 is a multi-prismatic shape. Through the edges of the quadrangular prism, the driving rod 33 is driven to rotate synchronously when the rotating cylinder 32 rotates. At the same time, the driving rod 33 can slide in the rotating cylinder 32.

[0042] Further, the above-mentioned pretreatment device further includes a pressure sensing component 4 disposed on the grinding mechanism 3, and 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 connection disk 41 fixedly connected to the outer circle of the driving rod 33. The connection disk 41 is disposed between the rotating cylinder 32 and the connection plate 21. When the driving rod 33 rotates, it drives the connection disk 41 to rotate synchronously. At the same time, when the driving rod 33 slides in the rotating cylinder 32, the connection disk 41 moves. A synchronous disk 42 is rotatably connected to the outer circle of the connection disk 41 through a bearing. Through the setting of the connection disk 41 and the bearing, when the synchronous disk 42 is restricted from rotating, it will not prevent the driving rod 33 from rotating, and at the same time, the driving rod 33 and the synchronous disk 42 rotate synchronously. Side plates 43 are fixedly connected to both sides of the synchronous disk 42 respectively. When the driving rod 33 moves, it drives the side plates 43 to move synchronously. Moving rods 44 are fixedly connected to the sides of the two side plates 43 away from the connection plate 21 respectively. Adjusting plates 45 are slidably connected to the two moving rods 44 respectively. The two adjusting plates 45 are fixedly connected to the side of the mounting plate 1. Through the limiting effect of the moving rods 44 and the adjusting plates 45, the synchronous disk 42 is prevented from rotating. Limit disks 46 are fixedly connected to the ends of the two moving rods 44 away from the side plates 43 respectively. Through the setting of the limit disks 46, the moving rods 44 are prevented from detaching from the adjusting plates 45. Springs 47 are sleeved and installed on the outer circles of the two moving rods 44 respectively. The springs 47 are disposed between the side plates 43 and the adjusting plates 45. Through the elastic force of the springs 47, after the springs 47 are compressed and then release the elastic force, the grinding wheel 2 is pressed tightly against the substrate. Detection plates 48 are slidably connected to the two moving rods 44 respectively. The detection plates 48 are disposed between the adjusting plates 45 and the springs 47. Pressure sensors 49 are installed in the two adjusting plates 45 respectively. The detection ends of the pressure sensors 49 are fixedly connected to the detection plates 48. The pressure sensors 49 detect the elastic force at one end of the spring 47 through the detection plates 48, so as to know the pressure of the grinding wheel 2 on the substrate.

[0043] A protective cover can be installed at the positions of the synchronous disk 42 and the side plates 43 to isolate the oxidized layer powder and base powder ground off, prevent impurities from entering the sliding positions of the moving rods 44 and the adjusting plates 45, and the sliding positions of the rotating cylinder 32 and the driving rod 33, and ensure smooth movement.

[0044] Specifically, the above-mentioned pretreatment 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 drives 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. Slide rails 54 are 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 blocks 53 and the slide rails 54, the movement of the mounting plate 1 is stable.

[0045] In this embodiment, the above-mentioned pretreatment device includes a lateral driving assembly 7 for driving the grinding wheel 2 to perform lateral grinding on the substrate. The lateral driving assembly 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 drives 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 drives 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 "C" shape. A second servo motor 74 is installed in the mounting frame 73. The output end of the second servo motor 74 passes through the mounting frame 73 and is fixedly connected to the first threaded rod 72. After the second servo motor 74 is started, it drives 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. By limiting the movement of the driving block 71 when the first limiting rod 75 moves, the movement of the driving block 71 is stable.

[0046] Further, the above-mentioned preprocessing device further includes a vertical driving mechanism 8 for driving the grinding wheel 2 to vertically grind the base material. The vertical driving mechanism 8 includes a bottom plate 81 disposed below the grinding wheel 2. Two fixing frames 82 are fixedly connected to the top of the bottom plate 81. Two vertical plates 83 are respectively fixedly connected to one side of the two fixing frames 82 away from the bottom plate 81, and the positions of the fixing frames 82 and the vertical plates 83 are fixed. The two vertical plates 83 are symmetrically disposed on both sides of the grinding wheel 2. The tops of the two vertical plates 83 on the side away from each other are respectively fixedly connected to a top plate 84. A second limiting rod 85 is fixedly connected between one top plate 84 and the bottom 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, and the sliding sleeve 86 cooperates with the second limiting rod 85 to limit the position when the transverse driving assembly 7 moves. A second threaded rod 87 is rotatably connected between the other top plate 84 and the bottom plate 81, and the second threaded rod 87 remains in place and rotates. A threaded sleeve 88 is threadedly connected to the second threaded rod 87. When the second threaded rod 87 rotates, it drives the threaded sleeve 88 to move along the length direction of the second threaded rod 87. The other end of the first limiting rod 75 is fixedly connected to the threaded sleeve 88. One 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 driving 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 disposed 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. When the second bevel gear 811 rotates, it drives the second threaded rod 87 to rotate synchronously.

[0047] Furthermore, the above-mentioned preprocessing device further includes a calibration assembly 9 for monitoring the fitting degree between the grinding wheel 2 and the base material. The calibration assembly 9 includes two fixing plates 91 installed on the side surface of the bottom plate 81. Two second push rod motors 92 are respectively installed on the tops of the two fixing plates 91. The output end of the second push rod motor 92 is fixedly connected to a first displacement gauge 93. After the second push rod motor 92 is started, it drives the detection end of the first displacement gauge 93 to contact the base material. Two fixing brackets 94 are respectively installed on the opposite sides of the two vertical plates 83. Two third push rod motors 95 are respectively installed in the two fixing brackets 94. The output end of the third push rod motor 95 is fixedly connected to a second displacement gauge 96. After the third push rod motor 95 is started, it drives the detection end of the second displacement gauge 96 to contact the base material. The position and direction of the bottom plate 81 are adjusted according to the data of the two first displacement gauges 93 and the second displacement gauge 96 to ensure that the grinding wheel 2 is closely fitted with the base material.

[0048] Finally, the above-mentioned preprocessing device further includes a control display screen. The first servo motor 31, the pressure sensor 49, the first push rod motor 51, the second servo motor 74, the third servo motor 89, the second push rod motor 92, the first displacement gauge 93, the third push rod motor 95, and the second displacement gauge 96 are all electrically connected to the control display screen. After the thickness of the grinding wheel 2 becomes thinner after grinding, the distance between the two ends of the spring 47 becomes longer, so that the pressure exerted by the spring 47 on the substrate by the grinding wheel 2 decreases. The first push rod motor 51 is started to drive the mounting plate 1 close to the substrate by the reaction force and squeeze the spring 47, so as to ensure that the pressure of the grinding wheel 2 on the substrate is constant. At the same time, the control display screen obtains the change of the average value of the two groups of pressure sensors 49 to know the change of the pressure of the grinding wheel 2 on the substrate. During the first grinding, due to the unevenness of the substrate surface, a large pressure change occurs at the convex position. Therefore, during the second grinding, the first push rod motor 51 is started at the convex position, and the mounting plate 1 is driven close to the substrate by the reaction force, so as to squeeze the spring 47 to increase the elastic force, making the surface of the substrate smooth.

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

[0050] In this embodiment, first, the device is placed beside the substrate, so that the grinding wheel 2 contacts the substrate and squeezes the two groups of springs 47 at the same time. The two groups of second push rod motors 92 and the two groups of third push rod motors 95 are started through the control display screen to drive the first displacement gauge 93 and the second displacement gauge 96 to contact the substrate. By observing the four groups of data displayed on the control display screen, the position and tilt angle of the bottom plate 81 are adjusted so that the data of the two groups of first displacement gauges 93 and the two groups of second displacement gauges 96 are the same. At this time, the grinding surface of the grinding wheel 2 is closely attached to the substrate.

[0051] When grinding, first, the first servo motor 31 is started to drive the rotating cylinder 32 to rotate, and the connecting plate 21 is driven through the driving rod 33, thereby driving the grinding wheel 2 to rotate. The second servo motor 74 is started to drive the first threaded rod 72 to rotate. When the first threaded rod 72 rotates, it drives the driving block 71 to move horizontally. At the same time, the driving block 71 moves smoothly under the limiting action of the first limiting rod 75, driving the grinding wheel 2 to perform horizontal grinding. After the horizontal grinding at the same height is completed, the third servo motor 89 is started to drive the first bevel gear 810 to rotate, and the second threaded rod 87 is driven to rotate through the second bevel gear 811, driving the threaded sleeve 88 to move vertically, so that the driving block 71 and the first limiting rod 75 move smoothly under the limiting action of the second limiting rod 85 and the sliding sleeve 86, thereby driving the grinding wheel 2 to change its height, and comprehensively grinding the substrate through the cooperation of the horizontal driving assembly 7 and the vertical driving mechanism 8.

[0052] During the grinding process, after the thickness of the grinding wheel 2 becomes thinner after grinding, the spring 47 releases elastic force, so that the pressure of the grinding wheel 2 on the substrate decreases, and the elastic force of the spring 47 sensed by the two groups of pressure sensors 49 also decreases. At this time, the first push rod motor 51 is started, and the mounting plate 1 is driven to approach the substrate by the reaction force of the first push rod motor 51. At the same time, the adjusting plate 45 approaches the substrate, so that the spring 47 is squeezed. At the same time, the display screen is controlled to take the average value of the two groups of pressure sensors 49 as the pressure of the grinding wheel 2 on the substrate, and cooperate with the adjustment of the first push rod motor 51 to ensure that the pressure of the grinding wheel 2 on the substrate is constant.

[0053] When the substrate is comprehensively ground for the first time, due to the unevenness of the substrate surface, a large pressure change occurs at the protruding position, and the pressure sensor 49 senses a large change at the protruding position. Therefore, when grinding for the second time, the first push rod motor 51 is started at the protruding position to squeeze the spring 47 to increase the elastic force, so as to increase the pressure of the grinding wheel 2 on the substrate at the protruding position, and make the surface of the substrate smooth.

[0054] After grinding is completed, the grinding wheel 2 is replaced with a wire brush, which is driven by the grinding mechanism 3, and cooperates with the lateral driving assembly 7 and the vertical driving mechanism 8 to scrape the scratches on the surface of the ground substrate, which is convenient for increasing the contact area between the coating and the substrate and ensuring the strength of the coating.

[0055] The above specific embodiments are only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
