Description

Technical Field

[0001] The invention relates to the technical field of color-coated plate processing and production, in particular to a corrosion-resistant nanographene color-coated plate and a production device for the color-coated plate. Background Art

[0002] Color steel plate refers to color-coated steel plate. Color-coated steel plate is a steel plate with an organic coating. Color steel plate is divided into single plate, color steel composite plate, floor decking plate, etc. It is widely used in large public buildings, public factories, mobile houses, and the walls and roofs of integrated houses. The substrates of color steel plate are cold-rolled substrates, hot-dip galvanized substrates and electro-galvanized substrates. The coating types can be divided into polyester, silicon-modified polyester, polyvinylidene fluoride and plastic sol. The surface state of color steel plate can be divided into coated plate, embossed plate and printed plate. Color steel plate is widely used in construction, home appliances, transportation and other industries;

[0003] Graphene is a two-dimensional carbon nanomaterial composed of carbon atoms in a hexagonal honeycomb lattice with sp2 hybrid orbitals. It has excellent optical, electrical, and mechanical properties, and has important application prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery. Anti-corrosion coatings can be obtained by dispersing graphene into organic coatings. The anti-corrosion coatings combine the adhesion, flexibility, and processability of organic coatings with the barrier properties, mechanical properties, heat resistance, and chemical structure stability of two-dimensional carbon nanomaterials, and are considered to be the most promising anti-corrosion materials. In the process of curing and film formation of organic coatings, micropores are inevitable, and corrosion factors will invade the metal matrix through the micropores. Graphene acts as a filler to block the micropores and play an excellent corrosion protection role.

[0004] The utility model with announcement number CN213731041U specifically discloses a polishing device for color steel plates. By arranging a first support platform, a second support platform, a first press platform and a second press platform, the color steel plates are lifted up and transported by the first support platform and the second support platform, so that the color steel plates will not sink during transportation. The steel plates are pressed by the first press platform and the second press platform. Therefore, when the steel plates are polished, the color steel plates are tightly pressed by the first support platform, the second support platform, the first press platform and the second press platform, thereby preventing the color steel plates from shaking, thereby fixing the color steel plates firmly, thereby avoiding scratches on the surface of the color steel plates during polishing, and improving the polishing effect of the color steel plates.

[0005] In the prior art, color steel plates need to be cut according to customer-customized sizes. There are burrs on the edges of the cut color steel plates. In the subsequent use process, the edges of the color steel plates need to be ground and polished, otherwise it will affect the waterproofness of the edges when multiple pieces of the color steel plates are subsequently spliced. In the prior art, grinding and polishing of color steel plates requires two processing steps, and most of them are done manually. This method not only reduces the production efficiency of color steel plates, but also increases the labor intensity.

The upper end surface of the grinding plate 1 33 is vertically fixedly connected with a guide column 32, and the upper end of the guide column 32 passes through the grinding box 31 and is movably connected to the grinding box 31. The guide column 32 located in the grinding box 31 is sleeved with an extrusion spring 35 on the outside, and one end of the extrusion spring 35 is fixed to the grinding box 31, and the other end is fixed to the grinding plate 1 33;

[0045] A port polishing assembly 7 is provided on the right side of the side polishing assembly;

[0046] Specifically, the port grinding assembly 7 includes an upper conveying roller 74 and a lower conveying roller 73 which are symmetrically distributed up and down. Support plates 2 are symmetrically distributed and fixed on the front and rear sides of the processing platform 1. Both ends of the port grinding assembly 7 and the spinning assembly 6 are rotatably connected to the support plate 2. The upper end surface of the processing platform 1 and the corresponding positions of the port grinding assembly 7 are provided with a mounting groove 11. The lower conveying roller 73 is located inside the mounting groove 11. Both ends of the lower conveying roller 73 and the upper conveying roller 74 are fixedly connected with a gear 2 75. The two gears 2 75 are meshed and connected. The gears 2 75 are both arranged in the two support plates 2 of the hollow structure. The rear end surface of the support plate 2 and the corresponding position of the lower conveying roller 73 A motor 2 72 is fixed, and the output shaft of the motor 2 72 is fixed to the gear 2 75 at the front end of the lower conveying roller 73, and a pneumatic joint 71 is fixed at the corresponding position of the front support plate 2 and the front ends of the upper conveying roller 74 and the lower conveying roller 73. The upper conveying roller 74 and the lower conveying roller 73 have hollow structures inside, and the pneumatic joint 71 is connected to the inside of the upper conveying roller 74 and the lower conveying roller 73. The outer rings of the upper conveying roller 74 and the lower conveying roller 73 are equidistantly provided with air holes 78, and the air holes 78 are strip-shaped in structure. An elastic grinding sheet 76 with a wavy structure is fixed inside the air holes 78, and a rubber layer 77 is fixed on the surface of the upper conveying roller 74 and the lower conveying roller 73 between adjacent air holes 78.

[0047] By adopting the above technical solution, the user inputs the size of the color-coated plate into the controller, and the controller controls the operation of the device. One end of the color-coated plate passes through the left platform of the processing platform 1, and is led into the grinding box 31 through the left opening of the grinding box 31. Then, one end of the color-coated plate is located between the upper conveying roller 74 and the lower conveying roller 73. In the subsequent spinning process of the color-coated plate, the motor 2 72 drives the upper conveying roller 74 and the lower conveying roller 73 to rotate counterclockwise, and the upper conveying roller 74 and the lower conveying roller 73 are driven by the meshing of the gear 2 75. One end of the color-coated plate located between the two is rotated and conveyed to the spinning component 6, and the burrs on the edge of the color-coated plate are polished and polished by the grinding plate 1 33 and the grinding plate 2 34 during the conveying process of the color-coated plate. The guide column 32 is movably connected to the grinding box 31 and is designed through the extrusion spring 35 so that the grinding plate 1 33 and the grinding plate 2 34 can still be close to the edge of the color-coated plate for color-coated plates of different thicknesses in the future.

[0048] When the left and right edges of the color-coated plate of a specified size are displaced to between the upper conveying roller 74 and the lower conveying roller 73 (mainly achieved by the displacement sensor built into the hot air polishing box 31), the motor 2 72 stops driving, and then the external air pump equipment is connected to the two pneumatic joints 71 through a pipeline to inject a certain amount of gas into the upper conveying roller 74 and the lower conveying roller 73. The injected gas will squeeze the elastic polishing sheet 76 outward through the air hole 78, causing the elastic polishing sheet 76 to expand outward. At this time, the motor 2 72 rotates clockwise to drive the upper conveying roller 74 and the lower conveying roller 73 to rotate at high speed, and the burrs on the cut edges of the color-coated plate between the upper conveying roller 74 and the lower conveying roller 73 are polished and polished by the protruding elastic polishing sheet 76. Then the pneumatic joint 71 is controlled to release pressure to discharge the air inside the upper conveying roller 74 and the lower conveying roller 73, and the elastic polishing sheet 76 is reset under its own elastic force. Then the motor 2 72 continues to rotate counterclockwise to drive the upper conveying roller 74 and the lower conveying roller 73 to convey the polished color-coated plate.

[0049] Specifically, a spinning assembly 6 for rotary stamping the color-coated plate is provided in the middle of the upper end surface of the processing platform 1;

[0050] The spinning assembly 6 includes a mold roller 62 rotatably connected to a mounting groove 11 on the upper end surface of the processing platform 1, a spinning roller 61 is arranged above the mold roller 62, and shafts 69 are fixed at both ends of the spinning roller 61 and the mold roller 62. The spinning roller 61 and the mold roller 62 are rotatably connected to the two ends of the inner wall of the support plate 2 respectively through the shaft 69, and the outer surface of the mold roller 62 is provided with stamping grooves 64 at equal distances in an annular shape, and the front and rear ends of the stamping grooves 64 are designed as open structures.

[0051] The surfaces of the front end shafts 69 of the spinning roller 61 and the mold roller 62 are both sleeved and fixed with a gear 67, and the two gears 67 are meshed and connected. A motor 5 is fixed to the front end surface of the support plate 2 on the front side, and the output shaft of the motor 5 is fixed to the front end shaft 69 of the mold roller 62. The surfaces of the rear end shafts 69 of the spinning roller 61 and the mold roller 62 are both sleeved and fixed with fan blades 8. The corresponding positions of the support plate 2 and the fan blades 8 on the rear side are penetrated by a mounting groove 2 68, and a bracket is fixed in the mounting groove 2 68, which is fixed to the shaft 69 through the bracket. The spinning roller 61 is designed in a cylindrical structure with openings at both ends. A hollow plate 611 is fixed, and movable grooves are equidistantly opened in an outer ring of the spinning roller 61, and a stamping plate 63 is movably connected in the movable groove. A supporting plate 633 with an arc structure is fixed at one end of the stamping plate 63 located in the spinning roller 61, and several supporting plates 633 are provided with expansion bags 65, and both ends of the expansion bags 65 are fixed to the hollow plate 611. A rectangular spring 632 is provided on the supporting plate 633, and the rectangular spring 632 is sleeved on the outside of the stamping plate 63. The internal hollow structure of the stamping plate 63 is designed and heat dissipation teeth are fixed at equal distances, and both ends of the stamping plate 63 are open.

[0052] In actual use, since different sizes of color-coated sheets have different processing requirements for the corrugated depth and corrugated width of stamping, the processing requirements of color-coated sheets of different sizes are generally achieved by replacing the mold. This method not only reduces the processing efficiency of the color-coated sheets, but also requires repeated adjustments after replacement;

[0053] The present application changes the spacing between adjacent stamping plates 63 when adjusting the width of the color-coated plate. The main method is as follows: according to the stamping width requirement, the user selects to adjust the stamping plates 63 at different positions to be hidden in the spinning roller 61, and the remaining stamping plates 63 extend out of the spinning roller 61. At this time, the controller controls the built-in electromagnet 634 in the active slot at the stamping plate 63 that does not need to be extended to guide the electromagnetic suction of the stamping plate 63, and then the external electrorheological fluid passes through the pump through the pipeline joint 691, and the electrorheological fluid is transported to the expansion chamber in the spinning roller 61 through the pipeline joint 691. In the expansion bag 65, the expansion bag 65 is now expanded, expanding outward to squeeze the support plate 633. At this time, the stamping plate 63 (not fixed by magnetic attraction) connected to the support plate 633 extends outward through the movable groove, and the magnetically fixed stamping plate 63 cannot be displaced. When the adjustment is completed, the electrorheological fluid conducts electricity, so that the electrorheological fluid in the expansion bag 65 solidifies, and is used for the subsequent stamping plate 63 to stamp the color-coated plate. The force is fed back to the solidified expansion bag 65 to share the force. The above method can realize the adjustment of different stamping corrugated widths on the surface of the color-coated plate;

[0054] Corrugation depth adjustment;

[0055] According to the same principle as above, the hollow plate 611 on one side of the spinning roller 61 has a built-in displacement sensor, which can detect the displacement distance of each unique stamping plate 63 and feed it back to the controller, and the controller controls the electromagnet 634 at the corresponding position to guide the electromagnetic attraction to fix the stamping plate 63 in the movable groove;

[0056] The long working time of the stamping plate 63 and the stamping groove 64 will lead to high temperature. The stamping plate 63 and the stamping groove 64 in the high temperature state are easy to affect the paint surface of the color-coated plate. Therefore, in order to reduce the impact on the color-coated plate and avoid high-temperature metal fatigue at the stamping plate 63 and the stamping groove 64, fan blades 8 are designed at the shaft 69. When the motor 5 drives it to rotate, the fan blades 8 rotate together, and the air flow at the stamping plate 63 with a hollow structure and the stamping groove 64 with openings at both ends is accelerated to achieve air cooling. In addition, the built-in heat dissipation fins 631 of the stamping plate 63 can replicate heat conduction and improve heat dissipation efficiency.

[0057] Working principle: During operation, the user inputs the size of the color-coated plate into the controller, and the controller controls the operation of the device. One end of the color-coated plate passes through the left platform of the processing platform 1, and is led into the grinding box 31 through the left opening of the grinding box 31. Then, one end of the color-coated plate is located between the upper conveying roller 74 and the lower conveying roller 73. In the subsequent spinning process of the color-coated plate, the motor 2 72 drives the upper conveying roller 74 and the lower conveying roller 73 to rotate counterclockwise. The upper conveying roller 74 and the lower conveying roller 73 are driven by the meshing of the gear 2 75. One end of the color-coated plate located between the two is rotated and conveyed to the spinning component 6. In the process of conveying the color-coated plate, the burrs on the edge of the color-coated plate are polished and polished by the grinding plate 1 33 and the grinding plate 2 34. The guide column 32 is movably connected to the grinding box 31 and is designed through the extrusion spring 35 so that the grinding plate 1 33 and the grinding plate 2 34 can still be close to the edge of the color-coated plate for color-coated plates of different thicknesses in the future.

[0058] When the left and right edges of the color-coated plate of the specified size are displaced to between the upper conveying roller 74 and the lower conveying roller 73 (mainly realized by the displacement sensor built into the hot air grinding box 31), the motor 2 72 stops driving, and then the external air pump equipment is connected to the two pneumatic joints 71 through the pipeline, and a certain amount of gas is injected into the upper conveying roller 74 and the lower conveying roller 73. The injected gas will squeeze the elastic grinding sheet 76 outward through the air hole 78, so that the elastic grinding sheet 76 expands outward. At this time, the motor 2 72 rotates clockwise to drive the upper conveying roller 74 and the lower conveying roller 73 to rotate at high speed, and the burrs on the cut edges of the color-coated plate between the upper conveying roller 74 and the lower conveying roller 73 are polished and polished by the protruding elastic grinding sheet 76. Then the pneumatic joint 71 is controlled to release pressure, and the air inside the upper conveying roller 74 and the lower conveying roller 73 is discharged. The elastic grinding sheet 76 is reset under its own elastic force, and then the motor 2 72 continues to rotate counterclockwise to drive the upper conveying roller 74 and the lower conveying roller 73 to convey the polished color-coated plate;

[0059] When the color-coated sheet moves between the spinning components 6, the motor 5 drives the mold roller 62 to rotate counterclockwise, and drives the upper spinning roller 61 to rotate through the two meshing gears 67, and squeezes the color-coated sheet into the stamping groove 64 through the stamping plate 63 to achieve stamping molding;

[0060] In actual use, since different sizes of color-coated sheets have different processing requirements for the corrugated depth and corrugated width of stamping, the processing requirements of color-coated sheets of different sizes are generally achieved by replacing the mold. This method not only reduces the processing efficiency of the color-coated sheets, but also requires repeated adjustments after replacement;

[0061] The present application changes the spacing between adjacent stamping plates 63 when adjusting the width of the color-coated plate. The main method is as follows: according to the stamping width requirement, the user selects to adjust the stamping plates 63 at different positions to be hidden in the spinning roller 61, and the remaining stamping plates 63 extend out of the spinning roller 61. At this time, the controller controls the built-in electromagnet 634 in the active slot at the stamping plate 63 that does not need to be extended to guide the electromagnetic suction of the stamping plate 63, and then the external electrorheological fluid passes through the pump through the pipeline joint 691, and the electrorheological fluid is transported to the expansion chamber in the spinning roller 61 through the pipeline joint 691. In the expansion bag 65, the expansion bag 65 is now expanded, expanding outward to squeeze the support plate 633. At this time, the stamping plate 63 (not fixed by magnetic attraction) connected to the support plate 633 extends outward through the movable groove, and the magnetically fixed stamping plate 63 cannot be displaced. When the adjustment is completed, the electrorheological fluid conducts electricity, so that the electrorheological fluid in the expansion bag 65 solidifies, and is used for the subsequent stamping plate 63 to stamp the color-coated plate. The force is fed back to the solidified expansion bag 65 to share the force. The above method can realize the adjustment of different stamping corrugated widths on the surface of the color-coated plate;

[0062] Corrugation depth adjustment;

[0063] According to the same principle as above, the hollow plate 611 on one side of the spinning roller 61 has a built-in displacement sensor, which can detect the displacement distance of each unique stamping plate 63 and feed it back to the controller, and the controller controls the electromagnet 634 at the corresponding position to guide the electromagnetic attraction to fix the stamping plate 63 in the movable groove;

[0064] The long working time of the stamping plate 63 and the stamping groove 64 will lead to high temperature. The stamping plate 63 and the stamping groove 64 in the high temperature state are easy to affect the paint surface of the color-coated plate. Therefore, in order to reduce the impact on the color-coated plate and avoid high-temperature metal fatigue at the stamping plate 63 and the stamping groove 64, fan blades 8 are designed at the shaft 69. When the motor 5 drives it to rotate, the fan blades 8 rotate together, and the air flow at the stamping plate 63 with a hollow structure and the stamping groove 64 with openings at both ends is accelerated to achieve air cooling. In addition, the built-in heat dissipation fins 631 of the stamping plate 63 can replicate heat conduction and improve heat dissipation efficiency.
