[0002] Water-based graphene clothing leather is a new type of material that combines the excellent properties of graphene and the convenience of water-based coatings. Water-based graphene clothing leather is usually made by dispersing graphene materials in an aqueous medium to form a graphene dispersion, and then mixing the graphene dispersion with an aqueous resin in a certain proportion, stirring and mixing to form a graphene composite slurry, and then coating the graphene composite slurry on the surface of the substrate fabric, and finally drying and curing the coating to make it tightly bonded to the substrate fabric to obtain the graphene clothing leather material.

[0024] Furthermore, the transmission mechanism includes a driving shaft 101 that is rotatably connected to the inner side of the middle groove 4, and a driven pulley 104 that is fixed to the outer side of the driven shaft 102. A driving pulley 105 is fixed to the outer side of the driving shaft 101. The driving pulley 105 and the driven pulley 104 are connected to each other through a synchronous belt 106. Two first traction wheels 108 are fixed to both ends of the driving shaft 101. Through the transmission mechanism, when the support plate 3 moves, the driven shaft 102 in the vibration leveling mechanism can be synchronously driven to rotate, thereby driving multiple knocking wheels 107 to rotate. The multiple knocking wheels 107 respectively drive multiple knocking rods 8 to rotate a certain angle and then quickly reverse and reset, so that the metal spring piece 6 can be knocked to make the metal spring piece 6 vibrate, thereby accelerating the leveling speed of the graphene composite slurry.

[0025] Furthermore, two side grooves 201 are provided inside the support plate 3 at both sides of the middle groove 4, and a rotating drum 202 is rotatably connected to the inside of the two side grooves 201, and two spiral convex strips 203 in opposite directions are provided at both ends of the outer sides of the two rotating drums 202, and two second traction wheels 204 are fixed at both ends of the two rotating drums 202, and two friction plates 13 are fixed on both sides of the inside of the frame 1, and the two friction plates 13 respectively drive the driving shaft 101 and the rotating drum 202 to rotate through friction with the first traction wheel 108 and the second traction wheel 204; The two rotating drums 202 located on both sides of the support plate 3 are in contact with the lower surface of the base material fabric, and the second traction wheels 204 at both ends of each rotating drum 202 are also in contact with the surfaces of the two friction plates 13 at the same time.

Therefore, when the rotating drum 202 rotates, the spiral ridges 203 at both ends can apply friction forces pointing to both sides to the base material fabric, so that the base material fabric can be spread out to both sides, further avoiding wrinkle deformation of the base material fabric.

[0026] Furthermore, two guide grooves 301 are provided on both sides of the interior of the frame 1, and two rollers 302 (such as rollers 302) movably adapted to the guide grooves 301 are rotatably inserted on one side of each support plate 3. Fig. 9 As shown), each support plate 3 moves along the contour of the guide groove 301 through a roller 302, and a fixing frame 401 is fixed at the position corresponding to each support plate 3 on the outer side of the conveyor belt 2, and each fixing frame 401 is movably connected to the support plate 3 at the corresponding position through a connecting rod 402; When the conveyor belt 2 rotates, it drives the multiple fixed frames 401 on its outside to rotate synchronously. The fixed frames 401 can apply pulling force to the multiple support plates 3 respectively through the multiple connecting rods 402. At the same time, under the active cooperation between the multiple rollers 302 and the guide groove 301, the conveyor belt 2 can drive the multiple support plates 3 to move cyclically along the contour trajectory of the guide groove 301 through the multiple connecting rods 402.

[0027] Further, the driving mechanism includes two belt rollers 502 rotatably connected to the inner side of the frame 1, a plurality of support rollers 503, and a first motor 501 installed on the outer side of the frame 1 for driving one of the belt rollers 502 to rotate, the conveyor belt 2 is transmission-connected to the outer sides of the two belt rollers 502, and the plurality of support rollers 503 guide and support the upper side of the conveyor belt 2; The conveyor belt 2 is driven to rotate by the driving mechanism, and the conveyor belt 2 drives the multiple support plates 3 and the multiple metal springs 6 to move at a speed greater than the moving speed of the coating device to pull the substrate cloth, so that the multiple metal springs 6 can slide relatively along the lower surface of the substrate cloth, and the multiple metal springs 6 can apply a horizontal sliding friction force to the substrate cloth from the lower surface. The sliding friction force acts evenly on the lower surface of the substrate cloth. The sliding friction force provides traction for the horizontal movement of the substrate cloth, so that the substrate cloth moves smoothly. The traction force applied to the substrate cloth by this traction method is more evenly distributed, avoiding wrinkles on the substrate cloth, and will not apply too much pulling force to the substrate cloth coated with the graphene composite slurry, thereby avoiding rebound and shrinkage of the substrate cloth after being stretched, thereby preventing the graphene coating on its surface from wrinkling and falling off from the surface of the substrate cloth.

At the same time, the graphene composite slurry stirring tank 604 can stir the graphene composite slurry inside, and then the stirred graphene composite slurry is extracted by the diaphragm pump 605, and then transported to the inside of the coating roller 602 through the feeding pipe 606, and finally evenly coated on the surface of the substrate fabric through the multiple coating holes on the outside of the coating roller 602, completing the coating process of the graphene clothing leather.

[0029] Furthermore, the drying device includes a shell 701 disposed at one end of the upper side of the frame 1, and a plurality of air inlet pipes 702 are disposed on the upper side of the shell 701, and a fan 704 is fixedly installed on the inner side of each air inlet pipe 702 through a bracket 703, and an electric heating wire 705 for heating air is installed on the inner side of each air inlet pipe 702 at a position below the fan 704; Multiple fans 704 of the drying device are operated to blow external air into the inner side of the shell 701 through the air inlet pipe 702. At the same time, the blown air is heated by the heating effect of the electric heating wire 705. The heated air dries the graphene composite slurry on the surface of the substrate fabric, so that the graphene composite slurry is quickly solidified, thereby forming a graphene clothing leather material.

[0030] Embodiment 2: This embodiment also provides a method for preparing water-based graphene clothing leather, which specifically comprises the following steps: Step 1: Coat the surface of the substrate cloth with graphene composite slurry by a coating device, and at the same time pull the substrate cloth, pull the substrate cloth coated with graphene composite slurry to the upper side of multiple support plates 3, drive the conveyor belt 2 to rotate by a driving mechanism, drive the multiple support plates 3 and the multiple metal shrapnel 6 to move, the conveyor belt 2 drives the multiple support plates 3 and the multiple metal shrapnel 6 to move at a speed greater than the speed at which the coating device pulls the substrate cloth, so that the multiple metal shrapnel 6 slides relatively along the lower surface of the substrate cloth, and the multiple metal shrapnel 6 applies a horizontal sliding friction force to the substrate cloth from the lower surface of the substrate cloth, and the sliding friction force provides traction for the horizontal movement of the substrate cloth; Step 2: When the substrate fabric coated with the graphene composite slurry is conveyed through the vibration leveling mechanism, the metal spring 6 therein generates continuous high-frequency vibration, and the vibration is transmitted to the graphene composite slurry on the upper surface of the substrate fabric, so that the graphene composite slurry on the upper surface of the substrate fabric is quickly leveled, so that the graphene composite slurry is evenly covered on the upper surface of the substrate fabric, and at the same time, the high-frequency vibration makes the graphene composite slurry penetrate into the gaps between the fibers of the substrate fabric; Step three, external air is blown into the inner side of the shell 701 through the drying device, and the blown air is heated by the heating effect of the electric heating wire 705. The heated air dries the graphene composite slurry on the surface of the substrate cloth, so that the graphene composite slurry is solidified to form a graphene clothing leather material.

[0031] Working principle: When in use, the substrate fabric used to produce graphene clothing leather is wound around the outside of the unwinding roller 601 of the coating device, and then one end of the substrate fabric is passed between the coating roller 602 and the traction roller 603, and the second motor 608 is controlled to drive the coating roller 602 to rotate, and the coating roller 602 drives the gear 607 at one end to rotate, and the gear 607 drives the other gear 607 to rotate in the opposite direction, thereby driving the traction roller 603 to rotate in the opposite direction, thereby driving the coating roller 602 and the traction roller 603. The roller 601 rotates at a constant speed in the opposite direction, thereby pulling the substrate fabric to move, so that the substrate fabric is released from the outside of the discharge roller 601. At the same time, the graphene composite slurry stirring tank 604 can stir the graphene composite slurry inside, and then the stirred graphene composite slurry is extracted through the diaphragm pump 605, and then transported to the inside of the coating roller 602 through the feeding pipe 606, and finally evenly coated on the surface of the substrate fabric through the multiple coating holes on the outside of the coating roller 602, completing the coating process of the graphene clothing leather; The coated substrate fabric continues to move to the top of the conveyor belt 2, and at the same time, the first motor 501 of the driving mechanism drives one of the belt rollers 502 to rotate, and this belt roller 502 drives the conveyor belt 2 and the other belt roller 502 to rotate synchronously, and multiple support rollers 503 can support and guide the conveyor belt 2, so that the upper side of the conveyor belt 2 moves linearly in the horizontal direction. When the upper side of the conveyor belt 2 moves horizontally and linearly, it drives the multiple fixing frames 401 on its outer side to move synchronously, and multiple connecting rods 402 can apply tension to the multiple support plates 3 respectively. At the same time, under the active cooperation between the multiple rollers 302 and the guide groove 301, the conveyor belt 2 can drive the multiple support plates 3 to move cyclically along the contour trajectory of the guide groove 301 through the multiple connecting rods 402. Since the substrate fabric moves to the top of the conveyor belt 2, the metal spring sheet 6 on the upper side of each support plate 3 can provide support for the lower side of the substrate fabric, and at the same time, the multiple support plates 3 and the multiple metal spring sheets 6 follow the upper side of the conveyor belt 2 to move horizontally and linearly synchronously, so that horizontal traction can be applied to the substrate fabric; It should be noted that the conveyor belt 2 drives the moving speed of the multiple support plates 3 and the multiple metal shrapnel 6 to be greater than the moving speed of the coating device pulling the substrate fabric, so that the multiple metal shrapnel 6 can slide relatively along the lower surface of the substrate fabric, and the multiple metal shrapnel 6 can apply a horizontal sliding friction force to the substrate fabric from the lower surface of the substrate fabric, and the sliding friction force acts evenly on the lower surface of the substrate fabric. The sliding friction force provides traction for the horizontal movement of the substrate fabric, so that the substrate fabric moves smoothly. Compared with the existing method of pulling the substrate fabric by rotating the roller, the traction force applied to the substrate fabric by this traction method is more evenly distributed, avoiding wrinkles on the substrate fabric, and will not apply too much tension to the substrate fabric coated with the graphene composite slurry, thereby avoiding the rebound and contraction of the substrate fabric after being stretched, thereby preventing the graphene coating on its surface from wrinkling and falling off from the surface of the substrate fabric, thereby improving the production quality of graphene clothing leather; When each support plate 3 supports the base material to move linearly on the upper side, the two first traction wheels 108 of the internal transmission mechanism are in contact with the upper sides of the two friction plates 13 inside the frame 1 respectively (such as Figure 5As shown), at this time, under the action of the friction force between the first traction wheel 108 and the friction plate 13, the two first traction wheels 108 can be driven to rotate, and the two first traction wheels 108 drive the driving shaft 101 to rotate, and the driving shaft 101 drives the driving pulley 105 to rotate, and the driving pulley 105 drives the driven pulley 104 to rotate through the synchronous belt 106, thereby driving the driven shaft 102 of the vibration leveling mechanism to rotate, and the driven shaft 102 drives multiple knocking wheels 107 on its outer side to rotate, and each knocking wheel 107 drives multiple driving teeth 109 on the outer side to rotate. It should be noted that the shape of the driving tooth 109 is a right-angled trapezoidal structure, and one end of each knocking rod 8 The knocking wheel 107 is rotatably connected to a sliding shaft 12, and a hammer 11 is fixed to the other end of each knocking rod 8. When the knocking wheel 107 drives the multiple pushing teeth 109 on its outer side to rotate, the inclined surface of each pushing tooth 109 can push the sliding shaft 12, thereby driving the knocking rod 8 to rotate a certain angle around the outer side of the fixed shaft 7, so that the hammer 11 at the other end of the knocking rod 8 is separated from the lower surface of the metal spring 6. At the same time, the knocking rod 8 drives the torsion spring 10 connected thereto to twist a certain angle, so that the torsion spring 10 accumulates force. As the knocking wheel 107 rotates, when the sliding shaft 12 is separated from the inclined surface of the pushing tooth 109, the inclined surface no longer supports the sliding shaft 12. At this time, The elastic force of the torsion spring 10 applies a reverse torque to the knocking rod 8, so that the knocking rod 8 quickly rotates in the reverse direction to reset, so that the sliding shaft 12 at one end of the knocking rod 8 quickly hits the bottom end of the inclined surface of an adjacent pushing tooth 109, and at the same time, the hammer 11 at the other end of the knocking rod 8 quickly knocks the lower surface of the metal dome 6, so that the metal dome 6 generates high-frequency vibration. As the transmission mechanism drives the driven shaft 102 of the vibration leveling mechanism to rotate continuously, it can drive the hammers 11 at one end of the knocking rods 8 to continuously knock the lower surface of the metal dome 6, so that the metal dome 6 generates continuous high-frequency vibration, and the metal dome 6 transmits the vibration to the base material cloth supported on the upper side of the metal dome 6. Thereby, the substrate fabric is driven to vibrate, and the vibration is transmitted to the graphene composite slurry on the upper surface of the substrate fabric again, so that the graphene composite slurry that is not evenly distributed on the upper surface of the substrate fabric is quickly leveled, so that the graphene composite slurry can quickly and evenly cover the upper surface of the substrate fabric, thereby improving the thickness uniformity of the graphene clothing leather. At the same time, the high-frequency vibration can also make the graphene composite slurry more fully penetrate into the gaps between the fibers of the substrate fabric, further improving the adhesion firmness between the graphene composite slurry and the surface of the substrate fabric, thereby better avoiding the wrinkling and falling off of the graphene layer and the substrate fabric, and further improving the preparation quality of the graphene clothing leather; While the support plate 3 drives the substrate fabric to move, the two rotating drums 202 located on both sides of the support plate 3 also contact the lower surface of the substrate fabric, and the second traction wheels 204 at both ends of each rotating drum 202 also contact the surfaces of the two friction plates 13 at the same time. Under the action of friction force, the second traction wheels 204 are driven to rotate, thereby driving the two rotating drums 202 to rotate. The two rotating drums 202 respectively drive the outer spiral ridges 203 to rotate, and the spiral directions of the spiral ridges 203 at both ends of the outer side of each rotating drum 202 are opposite. Therefore, when the rotating drum 202 rotates, the spiral ridges 203 at both ends can apply friction forces pointing to both sides to the substrate fabric, so that the substrate fabric can be spread out to both sides, further avoiding wrinkle deformation of the substrate fabric; When the graphene composite slurry is evenly covered on the upper surface of the substrate fabric, multiple support plates 3 pull the graphene clothing leather to the bottom of the drying device, and multiple fans 704 of the drying device are operated to blow external air into the inner side of the shell 701 through the air inlet pipe 702. At the same time, the blown air is heated by the heating effect of the electric heating wire 705. The heated air dries the graphene composite slurry on the surface of the substrate fabric, so that the graphene composite slurry is quickly solidified, thereby forming a graphene clothing leather material.
