The graphene thin material coiling device is mainly used for generating a primary processing material of graphene, and graphite powder is mainly used as a raw material in the device, and specifically, the graphite powder uses scale graphite powder with fewer layers. In the production process, graphite powder is added into the material spraying module 1, the graphite powder is mixed with high-speed airflow and then sprayed into the material spraying module 1, then the graphite powder is sprayed out from an outlet at the lower part of the material spraying module 1, so that the graphite powder is dispersed and sprayed on the liquid surface of the water tank 2, then the graphite powder at the upper part of the liquid surface is blown by crosswind blown by the wind blowing block 3 to form a graphite layer, thus the thickness of the graphite layer is greatly reduced, the adhesive tape 44 adhered with the graphite powder layer on the water tank 2 is adhered to the adhesive tape by pressing the adhesive tape surface of the adhesive tape 44 by the material receiving roller 42 of the material rolling module 4, then the adhesive tape 44 adhered with the graphite powder layer is reeled by the material rolling roller 43, thus the single thin graphite powder layer can be adhered to the adhesive tape of the material rolling roller 43, and the graphite powder layer can be conveniently adhered to the surface needing a graphene coating by the adhesive tape on the material rolling roller 43, the adhesive tape structure adhered to the workpiece is more simple to operate, higher in efficiency, capable of greatly reducing requirements on the surface appearance and size of the workpiece, and stronger in universality. Simultaneously will when the adhesive tape of adhesion graphite is peeled off, just in time can carry out the layering with the graphite powder layer for the thickness and the layer number structure of graphite powder layer more be close to the graphite alkene structure, be convenient for the production of graphite alkene coating on next step more.
As shown in fig. 1 during specific design, the pool 2 is further equipped with an ejecting roller 21 parallel to the material receiving roller 42, the upper surface of the ejecting roller 21 is located at the lower part of the powder layer, the upper surface of the ejecting roller 21 is flush with the liquid level of the pool 2, the ejecting roller 21 pushes the powder layer tightly on the glue coating layer of the lower adhesive tape 44 of the material receiving roller 42, the ejecting roller 21 is connected with a transmission structure, and the upper part of the ejecting roller 21 is identical to the linear velocity of the lower part of the material receiving roller 42. Therefore, the material receiving roller 42 and the material ejecting roller 21 are tightly propped against the surface of the upper part of the water pool 2, so that a blocking surface can be formed, a powder layer on the upper part of the water pool 2 can be conveniently blocked, and the blowing block 3 can conveniently blow powder on the upper part of the liquid level to the blocking surface of the material receiving roller 42 and the material ejecting roller 21, so that a single-layer powder layer is accumulated. Meanwhile, the jacking structure of the jacking roller and the material receiving roller 42 can jack the powder layer tightly on the surface of the rubberized layer of the rubberized fabric 44, so that the powder layer is bonded more firmly on the rubberized layer.
In a specific design, as shown in fig. 1, a drying block 5 capable of blowing dry hot air is assembled between the material receiving roller 42 and the material winding roller 43, and an air blowing port of the drying block 5 faces the powder layer on the rubberized fabric 44 between the material receiving roller 42 and the material winding roller 43. The drying block 5 blows dry hot air to blow dry the liquid on the surface of the powder layer, so that the powder layer is ensured to be coiled by the coiling roller 43 in a dry state. The coiling effect is better. A painting brush 6 is arranged between the drying block 5 and the material rolling roller 43, and the brush hair at the front end of the painting brush 6 is contacted with the powder layer on the adhesive plaster 44. The brushing may brush off excess layers of powder to which the tape 44 is adhered, resulting in a fewer number of graphene layers of graphite powder. Therefore, the graphene layer is more convenient to process and has higher efficiency.
In a specific design, as shown in fig. 1, an abrasive roller 7 is assembled between the painting roller 6 and the material rolling roller 43, the surface of the abrasive roller 7 is attached to the surface of the powder layer attached to the adhesive tape 44, the abrasive roller 7 rotates, and the attaching position of the abrasive roller 7 and the powder layer moves in the opposite direction. The grinding roller 7 can grind off a part of the powder layer on the surface of the adhesive tape 44, and can adhere the part, which is not adhered with the graphite powder, on the adhesive tape 44 to re-adhere the powder, so that the powder layer on the adhesive tape 44 has no dead angle, and the graphene layer processing effect is better.
When the material spraying module 1 is specifically designed, as shown in fig. 1, the material spraying module comprises a material discharging box 11, a material spraying nozzle 12 is assembled on the upper portion of the material discharging box 11, a conical bulk material disc 13 is assembled on the lower portion of the material spraying nozzle 12, and high-speed airflow mixed with graphite powder is introduced into the material spraying nozzle 12, so that when the material spraying module 1 starts to work, the high-speed airflow is wrapped by a graphite powder line and blows to the bulk material disc 13, and then the powder and the airflow are uniformly sprayed out from an outlet on the lower portion of the material discharging box 11 through the dispersing action of the bulk material disc 13, so that the powder can be prevented from accumulating, and the powder drops on the liquid level of the water pool 2 in a single-particle state. Meanwhile, the area of the outlet at the lower part of the material spraying nozzle 12 is smaller than that of the outlet at the lower part of the discharging box 11. When the high-speed airflow enters the discharge box 11, the speed is reduced, so that the speed of powder sprayed on the liquid surface of the water tank 2 by the discharge box 11 is low, the powder can be prevented from entering the liquid, meanwhile, the liquid surface fluctuation is large due to overlarge airflow, and the effect is better.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
