Description

Technical Field

[0001] This utility model relates to the field of fabric technology, specifically to a graphene conductive cloth coating equipment. Background Technology

[0002] Graphene's electrical conductivity primarily stems from its unique electronic structure. In graphene, each carbon atom contributes a π electron, which forms a continuous electron cloud within the plane. Because the carbon atoms in graphene are arranged in a highly symmetrical hexagonal structure, electrons can move freely throughout the plane, much like in metals. This free movement of electrons gives graphene its extremely high electrical conductivity.

[0003] Graphene's high electrical conductivity and thermal properties make it an ideal heating material for smart clothing. Graphene can also emit far-infrared waves, which can be used for heating and health benefits in functional garments. In existing technologies, during the coating of graphene dispersion onto a base fabric, the high surface energy of graphene causes it to decrease in temperature to achieve thermodynamic stability when present in solution or other media, leading to agglomeration and affecting its distribution on the base fabric. This presents an opportunity for technological improvement. Utility Model Content

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Example 1, in conjunction with Appendix Figure 1 A graphene conductive cloth coating device includes a base plate 1, an outer shell 2 on the base plate 1, the outer shell 2 including a frame and a top plate, the frame and the top plate being connected by several bolts for easy disassembly; a base cloth 3 is movably disposed under the base plate 1, the outside of the base cloth 3 being dragged by a winding device so that it can continuously move under the base plate 1.

[0024] Combined with appendix Figure 1 , 2 It also includes a pretreatment component; including a conveyor roller 4 rotatably mounted under the base plate 1; specifically, the two sides of the fixed plate 10 are provided with discs 11, and the conveyor roller 4 is rotatably connected between the two discs 11 to achieve rotation, which can provide fixed-point support for the base fabric 3, making the base fabric 3 taut and facilitating the coating operation.

[0025] Combined with appendix Figure 2 , 3 The base plate 1 is provided with a rectangular groove 5, and a coating roller 6 corresponding to the conveying roller 4 is rotatably installed in the rectangular groove 5. Specifically, the base plate 1 is provided with support plates 12 at both ends of the rectangular groove 5. The coating roller 6 is rotatably connected between the two support plates 12. A drive motor 13 is provided on the support plate 12 corresponding to one end of the shaft. The drive motor 13 drives the coating roller 6 to rotate. The coating roller 6 is used to pre-coat the base fabric 3 with adhesive to improve its adhesion during the process of spraying graphene dispersion.

[0026] In addition, an adhesive application groove 23 is provided on the outer shell 2 near the front end. The position and length of the adhesive application groove 23 correspond to the coating roller 6. The external adhesive storage device applies adhesive evenly to the coating roller 6 through the adhesive application groove 23.

[0027] Combined with appendix Figure 1 , 2 The distance between the coating roller 6 and the transmission roller 4 is adjustable; both sides of the base plate 1 are provided with fixing plates 7, and screws 8 are slidably connected to the fixing plates 7. Limiting nuts 9 are provided on the outer side of the screws 8 and at the upper and lower ends of the fixing plates 7; fixing plates 10 are rotatably provided at the lower end of the screws 8; thus, by loosening the fiber nuts 9, the position of the fixing plates 7 on the outer side of the screws 8 can be adjusted, thereby adjusting the distance between the coating roller 6 and the transmission roller 4 according to the thickness of the base fabric 3, so that the coating roller 6 is always in close contact with the base fabric 3;

[0028] Based on the above structure, a liquid collection tank 21 is provided on the base plate 1 and located behind the rectangular groove 5. The upper front end of the liquid collection tank 21 has an opening, and a scraper 22 is provided at the lowest end of the opening. The end of the scraper 22 contacts the coating roller 6. The longitudinal section of the scraper 22 is triangular, and the scraper 22 is inclined upward from one end away from the coating roller 6 to the other end. Thus, the scraper 22 can scrape off the coating roller 6. Since the distance between the scraper 22 and the coating roller 6 is fixed, the thickness of the adhesive on the coating roller 6 is constant after scraping off the excess adhesive, and the subsequent spraying is more uniform.

[0029] Combined with appendix Figure 2 , 4 The system also includes a spraying assembly; a dispersion box 14 is mounted on the outer shell 2, and an ultrasonic generator 15 is mounted on the front of the dispersion box 14. The output end of the ultrasonic generator 15 extends into the dispersion box 14 to vibrate and disperse the graphene dispersion, reducing agglomeration. A conduit 16 is connected to the outlet of the dispersion box 14, and a splitter 17 extends into the outer shell 2 at the end of the conduit 16. An infusion pump connected to the conduit 16 is located inside the dispersion box 14. A spraying pipe 18 is mounted at the lower end of the outer shell 2, and several nozzles are connected below the spraying pipe 18. Several branch pipes 19 are connected between the splitter 17 and the spraying pipe 18. Several through slots 20 that can accommodate the nozzles are mounted on the base plate 1. In the above structure, the graphene dispersion is uniformly sprayed onto the base fabric 3 through the conduit 16, the splitter 17, the spraying pipe 18, and several nozzles.
