The two limiting rings 304 are used to limit the graphite heat dissipation film on both sides of the outer side of the lower roller main body 302. The positions of the sleeve ring 303 and the limiting ring 304 on the outer side of the lower roller main body 302 are adjustable, which is suitable for limiting rings 304 of different widths. After adjustment, the sleeve ring 303 can be fastened through the locking bolts. The traction roller 10 is used to traction and auxiliary feeding of the graphite heat dissipation film on one side of the lower roller main body 302.

[0023] As shown in the figure, Figure 1 , Figure 3 and Figure 4 , the lifting adjusting assembly 4 is installed above the mounting seat 2. The lifting adjusting assembly 4 includes mounting frames 401, air cylinders 402, piston rods 403 and lifting plates 404. The air cylinders 402 are installed above the mounting frames 401.

Rotating motors 6 are installed on the outer side of the rotating shafts of the lower roller main body 302 and the upper roller main body 5. The rotating directions of the two rotating motors 6 are opposite. The air cylinders 402 and the piston rods 403 are used to drive the lifting of the lifting plates 404, so as to adjust the height of the upper roller main body 5 between the lifting plates 404. The lifting plates 404 are stably connected with the sliding strips 406 through the sliding grooves 405, so that the distance between the upper roller main body 5 and the lower roller main body 302 can be adjusted. The roller pressing device is suitable for the roller pressing of graphite heat dissipation films of different thicknesses.
