To sum up, under the circumstances of supporting chuck 3, rolling unit 4, conflict trigger unit 6, direction cutting unit 7 and central support unit 10 cooperation function, realize that automatic feeding, change and unloading three go on in step and the holistic continuous of three go on, need not manual operation and frequently open equipment and accomplish the forming process that graphite alkene heat dissipation was rolled up, whole work efficiency obtains improving, does benefit to improve equipment's life, alleviates workman intensity of labour.

The working principle is as follows: when the graphene heat dissipation film needs to be rolled, the graphene heat dissipation film is wound on the surface of the rolling unit 4, the rolling unit 4 is driven to rotate by the driving source inside the rolling roller replacing unit 2, so that the graphene heat dissipation film is rolled, the abutting triggering unit 6 is synchronously pushed and extruded in the process that the rolling outer diameter of the graphene heat dissipation film is gradually increased, when the graphene heat dissipation film is rolled to the set thickness, the abutting triggering switch inside the abutting triggering unit 6 is triggered at the moment, so that the rolling roller replacing unit 2 is separated from the rolling unit 4, then the graphene heat dissipation film is cut and a fracture of the graphene heat dissipation film is fixed by the guiding cutting unit 7, then the supporting chuck 3 is driven to slowly rotate by the rolling roller replacing unit 2, the supporting chuck 3 drives the formed graphene heat dissipation film roll to synchronously rotate towards the centralized placing block 9, and simultaneously the supporting chuck 3 drives the second new rolling unit 4 to synchronously rotate, when the second new winding unit 4 moves to the upper end of the winding roller replacing unit 2, the fracture of the graphene heat dissipation film is contacted and adhered to the surface of the winding unit 4, the winding unit 4 is replaced, the supporting chuck 3 continues to rotate for a certain angle, in the process, the formed graphene heat dissipation film rolls fall to the centralized placing block 9 under the pushing of the central supporting unit 10, the unloading work is completed, and meanwhile, the third winding unit 4 is in butt joint with the supporting chuck 3 through the storing and placing unit 8, and the loading work is completed.

When 6 internal triggers of butt trigger element, the unit 7 is tailor to the direction and presses down and the cutting to graphite alkene heat dissipation membrane, simultaneously along with supporting chuck 3's rotation, drive and support chuck 3 upside is removed to another rolling unit 4 adjacent with rolling unit 4, thereby contact and the adhesion at another rolling unit 4 surface with the graphite alkene heat dissipation membrane of disconnection, prepared rolling unit 4 joint is inside supporting chuck 3 simultaneously, rolling unit 4 that the rolling was accomplished simultaneously breaks away from supporting chuck 3 and unloads, thereby reach automatic cycle and accomplish the material loading, change and unloading, and the three goes on simultaneously, improve work efficiency's effect.
