[0002] Graphene film is a heat-conducting material with excellent performance, which is widely used in mobile phones, tablet computers, military, aerospace and other fields. The performance of artificially synthesized graphene film is better than that of the heat-conducting film made of natural graphite. The artificially synthesized graphite heat-conducting film is processed by procedures such as carbonization, graphitization, and calendering of polyimide film. Hot pressing is a machine that presses and extends rubber, silica gel or plastic into a film with a certain thickness and surface shape at a certain temperature, and can apply rubber to fiber cord fabric or steel cord fabric.

At this time, the gas inside the compressed elastic airbag is quickly discharged and transported to the jetting mechanism through the air delivery pipe, and finally ejected from the air outlet end of the jetting mechanism, thereby blowing the gas to flow, so that the gas on the surface of the graphene film is blown, which can accelerate the heat dissipation, and thus plays a cooling effect, helping to ensure the flatness of the graphene film during movement, avoiding film wrinkles. And as the pressing rod continues to rotate, when the pressing rod and the driven pressing plate are separated, and under the elastic force of the circular elastic member, the driven pressing plate rotates in the reverse direction.

An air duct 555 is fixedly connected to the top of the connecting housing 51, and the air duct 555 connects the air inlet of the elastic airbag 553 and the air inlet of the jet mechanism 554.

[0042] The surface of the driven pressure plate 551 is set as an arc surface. There are two circular elastic members 552, and the two circular elastic members 552 are symmetrically arranged. When the pressing rod 533 in rotation applies a top pressure to the driven pressure plate 551, combined with the hinged connection between the top end of the driven pressure plate 551 and the top of the inner wall of the connecting housing 51, and the surface of the driven pressure plate 551 is set as an arc surface, at this time, the driven pressure plate 551 under the top pressure rotates and presses the circular elastic member 552 and the elastic airbag 553.

And with the pressing of the rolling press roller 52 on the graphene film and the leftward movement of the graphene film, at this time, the rolling press roller 52 rotates clockwise, thereby rolling and pressing the graphene film and driving the three-jaw pressing device 53 to rotate clockwise. At this time, the driven pressing plate 551 on the jet cooling device 55 will be subjected to the top pressure of the rotating three-jaw pressing device 53, which helps with subsequent cooling. And when the rolling press roller 52 rotates, through the connection of the fixed sleeve 531, the three-jaw support member 532 also rotates together, thereby driving the pressing rod 533 to rotate. And when the ball 534 on the surface of the pressing rod 533 contacts the driven pressing plate 551, a top pressure is applied to the driven pressing plate 551. And with continuous rotation, with the rolling of the ball 534, when the pressing rod 533 presses the driven pressing plate 551, rolling friction is adopted, reducing the frictional resistance, which helps the entire structure to operate smoothly and is not prone to jamming. When the connecting shell 51 moves downward and presses the cleaning device 54 downward, the elastic support strip 541 is deformed by the pressure, and using the action and reaction, under the reaction force of the elastic support strip 541, the bottom of the cleaning device 542 fully contacts the surface of the graphene film. At this time, the connecting pipe 5421 applies pressure to the flexible pressing strip 5423 and the flexible wiping rod 5424, so that the surfaces of the flexible pressing strip 5423 and the flexible wiping rod 5424 are closely fitted with the surface of the graphene film. At this time, with the movement of the graphene film, the flexible wiping rod 5424 wipes off the dust and debris attached to the surface of the graphene film, and the flexible pressing strip 5423 presses the graphene film flexibly, so that the graphene film is not prone to wrinkling. At the same time, when the rotating pressing rod 533 applies a top pressure to the driven pressing plate 551, combined with the hinge between the top end of the driven pressing plate 551 and the inner wall top of the connecting shell 51, and the surface of the driven pressing plate 551 is set as an arc surface, at this time, the driven pressing plate 551 under the top pressure rotates and presses the circular elastic member 552 and the elastic airbag 553. At this time, the gas inside the compressed elastic airbag 553 is quickly discharged and is conveyed to the jetting mechanism 554 through the air delivery pipe 555 and finally sprayed out from the air outlet end of the jetting mechanism 554.Furthermore, it blows to drive the gas flow, causing the gas on the surface of the graphene film to be blown, which can accelerate heat dissipation, thereby achieving a cooling effect, helping to ensure the flatness of the graphene film during movement, avoiding film wrinkles, and as the pressing rod 533 continues to rotate, when the pressing rod 533 separates from the driven pressing plate 551, and under the elastic force of the circular elastic member 552, the driven pressing plate 551 rotates in the reverse direction. As the pressure disappears, the elastic airbag 553 expands, which further helps to continuously eject gas and accelerate the cooling of the graphene film. By utilizing the interaction between structures and making full use of gas flow, the structures are ingeniously connected together, which is safe and reliable, realizing multiple functions and improving the usability.
