Description

Technical Field

[0001] This utility model relates to the field of coating processing technology, and in particular to a graphene coating processing device. Background Technology

[0002] The layers in graphite crystals are relatively loosely spaced and bound together by van der Waals forces, while the carbon atoms in graphene are more flexible. Therefore, by peeling graphite layer by layer, high-performance monolayer graphene can be obtained. Graphene anti-corrosion coatings are coatings with high anti-corrosion capabilities obtained by adding graphene powder to solvent-based coatings and dispersing it evenly.

[0003] A search revealed that Chinese patent application CN212167907U discloses a graphene coating processing device, which mainly uses a graphene coating roll to attach a coating roll to the surface of graphene sheets, thereby quickly producing a graphene coating on the surface of the workpiece and greatly improving the production efficiency of graphene applications.

[0004] Compared with existing technologies in related fields, it can be seen that during the coating process, problems such as offset, tension, and wear of mechanical structures can cause wrinkles in the base material, which can lead to uneven coating and affect the quality of the coating. Utility Model Content

[0005] The purpose of this invention is to provide a graphene coating processing device to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A graphene coating processing device includes a frame, with an unwinding mechanism and a rewinding mechanism fixedly installed at both ends of the frame, and a guide roller mechanism, a tensioning unit, a flattening unit, a coating mechanism, a drying mechanism, and a flattening unit fixedly installed sequentially inside the frame.

[0008] The flattening unit includes a sleeve and a roller. The sleeve is fixedly installed inside the frame. An inlet valve is fixedly installed at the end of the sleeve. Flow control valves are fixedly arranged inside the sleeve. Rotary connecting seats are fixedly arranged on the outer surface of the sleeve. A hydraulic telescopic mechanism is fixedly installed on the rotary connecting seats. The hydraulic telescopic mechanism is connected to the flow control valves through the rotary connecting seats. An arc-shaped strip is fixedly installed on the telescopic end of the hydraulic telescopic mechanism. The roller is rotatably installed on the sleeve. Arc-shaped holes are arranged on the roller. The arc-shaped holes at both ends of the roller have opposite curve directions. The arc-shaped holes are slidably connected to the arc-shaped strip. A drive assembly is driven to the roller.

[0029] like Figures 1-8As shown, a graphene coating processing device includes a frame 1. An unwinding mechanism 2 and a rewinding mechanism 5 are fixedly installed at both ends of the frame 1. Inside the frame 1, a guide roller mechanism 8, a tensioning unit, a flattening unit, a coating mechanism 12, a drying mechanism 9, and a flattening unit are sequentially fixedly installed. The coating mechanism 12 is connected to an external graphene coating conveying device. The unwinding mechanism 2 unwinds the base material. After the base material is guided and limited by the guide roller mechanism 8, it is tensioned by the tensioning unit, flattened by the flattening unit, and then flattened by the tensioning unit. The flattening unit prevents the base material from loosening and wrinkling, which would affect the coating quality. The flattening unit flattens the base material, and the graphene coating is transported to the coating mechanism 12 by the external graphene coating conveying device. The coating mechanism 12 applies the graphene coating to the base material to form a coating. The coating on the base material is dried by the drying mechanism 9. After drying, the base material with the coating is flattened by the flattening unit and then enters the winding mechanism 5. The winding mechanism 5 winds up the finished base material with the coating to complete the graphene coating process.

[0030] like Figure 1 , Figure 3 , Figure 6As shown, the flattening unit includes a sleeve 304 and a roller 305. The sleeve 304 is fixedly installed inside the frame 1. An inlet valve 312 is fixedly installed at the end of the sleeve 304. Flow control valves 309 are fixedly arranged inside the sleeve 304. Rotary connecting seats 310 are fixedly arranged on the outer surface of the sleeve 304. A hydraulic telescopic mechanism 311 is fixedly installed on the rotary connecting seat 310. The hydraulic telescopic mechanism 311 is connected to the flow control valves 309 through the rotary connecting seat 310. An arc-shaped strip 307 is fixedly installed on the telescopic end of the hydraulic telescopic mechanism 311. The roller 305 is rotatably mounted on the sleeve 304. On the upper part, the roller 305 has arc-shaped holes 306 arranged on it. The arc-shaped holes 306 at both ends of the roller 305 have opposite curve directions. The arc-shaped holes 306 are slidably connected to the arc-shaped strips 307. A drive assembly is connected to the roller 305 and is fixedly installed in the frame 1. The inlet valve 312 is connected to an external hydraulic oil delivery device. The rotating connecting seat 310 includes two slidably connected annular seats. The two annular seats are respectively fixedly connected to the sleeve 304 and the hydraulic telescopic mechanism 311. The rotating connecting seat 310 enables the sleeve 304 and the hydraulic telescopic mechanism 311 to rotate and connect, preventing the sleeve 304 from rotating. The rotation of roller 305 is affected by the drive assembly, which drives the roller 305 to rotate. Roller 305 drives the arc-shaped strip 307 to rotate. The arc-shaped strips 307 at both ends of roller 305 have opposite curve directions. Roller 305 applies opposite forces to the base material on both sides through the arc-shaped strips 307, thus flattening the base material and effectively solving wrinkles and unevenness in the base material. This prevents wrinkles and unevenness from affecting the quality of subsequent coatings. The external hydraulic oil delivery device delivers hydraulic oil to sleeve 304 through inlet valve 312. The hydraulic oil in sleeve 304 is then controlled by flow control valve 30. 9 is fed into the hydraulic telescopic mechanism 311, and the amount of hydraulic oil entering the hydraulic telescopic mechanism 311 is controlled by the flow control valve 309, thereby controlling the extension of the hydraulic telescopic mechanism 311. The hydraulic telescopic mechanism 311 drives the arc-shaped strip 307 to move. By controlling the extension of the hydraulic telescopic mechanism 311, the extension height of the arc-shaped strip 307 is controlled, which facilitates the flattening of different base materials and different wrinkles, effectively adjusts the magnitude of the flattening force, ensures the flattening accuracy and effect, lays the foundation for the uniform coating of graphene coating, and ensures the coating quality.

[0031] like Figure 6 As shown, the drive assembly includes a dual-axis drive mechanism 301, which is fixedly installed inside the frame 1. A main shaft 302 is fixedly installed on the output shaft of the dual-axis drive mechanism 301, and a pulley mechanism 303 is fixedly installed on the main shaft 302. The pulley mechanism 303 is fixedly installed at both ends of the roller 305. The dual-axis drive mechanism 301 and the main shaft 302 drive the pulley mechanism 303 to rotate, and the pulley mechanism 303 drives the roller 305 to rotate stably, providing stable and uniform power for the flattening process.

[0032] like Figure 3 As shown, an anti-slip pad 308 is fixedly installed on the surface of the arc-shaped strip 307. The arc-shaped strip 307 is attached to the base material through the anti-slip pad 308. The arc-shaped strip 307 increases the friction with the base material through the anti-slip pad 308, preventing the base material from slipping during the flattening process, improving the flattening effect, and protecting the base material.

[0033] like Figure 1 , Figure 2 , Figure 4 As shown, the tensioning unit includes an electrically controlled telescopic mechanism 401. A buffer box 402 is fixedly installed on the telescopic end of the electrically controlled telescopic mechanism 401. A movable part 404 is slidably installed on the lower surface of the buffer box 402. A tensioning roller mechanism 406 is fixedly installed at the lower end of the movable part 404. A spring 405 is sleeved on the movable part 404. The two ends of the spring 405 are connected to the buffer box 402 and the tensioning roller mechanism 406. The electrically controlled telescopic mechanism 401 drives the buffer box 402 to move up and down. The buffer box 402 is connected to the movable part... 404 drives the tensioning roller mechanism 406 to tension the base material. When the tension of the base material changes, the force exerted by the tensioning roller mechanism 406 on the base material changes. The moving part 404 slides in the buffer box 402. At this time, the spring 405 plays a buffering and elastic restoring role. The spring 405 ensures that the tensioning roller mechanism 406 can always be in contact with the base material, effectively preventing the base material from wrinkling or being overstretched due to improper tension. In conjunction with the flattening unit, it further ensures the flatness of the base material and improves the coating processing quality.

[0034] like Figure 4 As shown, pressure sensors 403 are fixedly installed on both the upper and lower surfaces of the buffer box 402. The end of the movable part 404 is located in the middle of the pressure sensor 403. During the tensioning roller mechanism 406 tensions the base material, if the base material is loose or too tight, the movable part 404 will touch the pressure sensor 403 and apply force to the pressure sensor 403. The position of the movable part 404 on the buffer box 402 is determined by the change in the value detected by the pressure sensor 403. The extension length of the electronically controlled telescopic mechanism 401 can be adjusted in time, so that the tensioning roller mechanism 406 can better tension the base material and realize the dynamic adjustment of the base material tension.

[0035] like Figure 1 , Figure 2 , Figure 8As shown, the flattening unit includes a bidirectional adjustment mechanism 6, which is fixedly installed inside the frame 1. Two flattening rollers 7 are rotatably mounted on the bidirectional adjustment mechanism 6. Before coating and after drying, the base material enters between the two flattening rollers 7. The distance between the two flattening rollers 7 is adjusted by the bidirectional adjustment mechanism 6, thereby applying appropriate pressure to the base material through the flattening rollers 7. This allows the flattening rollers 7 to flatten and limit base materials and finished products of different sizes and thicknesses. It can eliminate unevenness on the base material before coating, which facilitates better coating of graphene coating on the base material, ensuring the quality and uniformity of the coating. After coating, it can flatten the finished product, which facilitates better winding of the finished product and ensures the quality of the finished coating.

[0036] like Figure 1 , Figure 5 As shown, a cleaning brush mechanism 10 and a dust collection mechanism 11 are fixedly installed on the guide roller mechanism 8. The dust collection mechanism 11 is located on both sides of the cleaning brush mechanism 10, and the cleaning brush mechanism 10 is located directly above the guide roller mechanism 8. The dust collection mechanism 11 is connected to an external dust collection device. During the graphene coating production process, the unwound base material passes between the guide roller mechanism 8 and the cleaning brush mechanism 10. The guide roller mechanism 8 guides the base material. When the base material is conveyed, the cleaning brush mechanism 10 brushes up the dust and other impurities on the base material to clean the surface of the base material and prevent impurities from affecting the adhesion and quality of the graphene coating. The external dust collection device extracts the dust and other impurities brushed off through the dust collection mechanism 11 to prevent the dust and other impurities from falling back onto the surface of the base material and affecting the coating quality.

[0037] Working principle: such as Figure 1 , Figure 2 , Figure 4 , Figure 7 As shown, the base material is unwound by the unwinding mechanism 2. The base material is guided and limited by the guide roller mechanism 8. The buffer box 402 moves up and down by the electrically controlled telescopic mechanism 401. The buffer box 402 drives the tensioning roller mechanism 406 to tension the base material through the movable part 404. When the tension of the base material changes, the force applied by the tensioning roller mechanism 406 to the base material changes. The movable part 404 slides in the buffer box 402. The spring 405 plays a buffering and elastic reset role. The movable part 404 will touch the pressure sensor 403 and apply a force to the pressure sensor 403. The position of the movable part 404 on the buffer box 402 is determined by the change in the value detected by the pressure sensor 403. By the change in the value detected by the pressure sensor 403, the telescopic length of the electrically controlled telescopic mechanism 401 can be adjusted in time, so that the tensioning roller mechanism 406 can better tension the base material.

[0038] like Figure 1 , Figure 3 , Figure 6As shown, the external hydraulic oil delivery device delivers hydraulic oil to the sleeve 304 through the inlet valve 312. The hydraulic oil in the sleeve 304 is delivered to the hydraulic telescopic mechanism 311 through the flow control valve 309. The flow control valve 309 controls the amount of hydraulic oil entering the hydraulic telescopic mechanism 311, thereby controlling the extension of the hydraulic telescopic mechanism 311. The hydraulic telescopic mechanism 311 drives the arc-shaped bar 307 to move, thereby controlling the extension of the arc-shaped bar 307.

[0039] like Figure 1 , Figure 3 , Figure 6 As shown, the dual-shaft drive mechanism 301 drives the pulley mechanism 303 to rotate, and the pulley mechanism 303 drives the roller 305 to rotate stably. The roller 305 drives the arc strip 307 and the anti-slip pad 308 to rotate. The arc strip 307 is attached to the base material through the anti-slip pad 308. The roller 305 applies opposite forces to the base material on both sides through the arc strip 307 and the anti-slip pad 308, thereby flattening the base material on both sides.

[0040] like Figure 1 , Figure 2 As shown, after the base material is flattened, graphene coating is applied to the base material by the coating mechanism 12 to form a coating on the base material. The coating on the base material is dried by the drying mechanism 9. After drying, the base material with coating is flattened by the flattening roller 7 and then enters the winding mechanism 5. The winding mechanism 5 winds up the finished base material with coating to complete the coating of graphene coating.

[0041] like Figure 1 , Figure 2 , Figure 8 As shown, before coating and after drying, the base material enters between two flattening rollers 7. The distance between the two flattening rollers 7 is adjusted by the bidirectional adjustment mechanism 6, so that the flattening rollers 7 apply appropriate pressure to the base material, enabling the flattening rollers 7 to flatten and limit the base material and the finished product.

[0042] like Figure 1 , Figure 5 As shown, during the base material conveying process, the cleaning brush mechanism 10 brushes up dust and other impurities on the base material to clean the surface of the base material. The external dust collection device extracts the dust and other impurities brushed off through the dust collection mechanism 11 to prevent dust and other impurities from falling back onto the base material surface and affecting the coating quality.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
