Specific implementation mode

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] The present invention provides a heat dissipation device for electrolytic copper foil. As Figures 1-4 shown, the heat dissipation device includes a bottom plate 1, a material guiding roller 2 rotatably installed on the bottom plate 1, and a winding roller 3 rotatably installed at one end of the bottom plate 1 through a bracket. Four cooling grooves 22 distributed in an annular array are formed in the material guiding roller 2. The two ends of the cooling grooves 22 are communicated with the rotary joint 21. A heat - conducting plate 23 is fixedly installed at the outer edge of the cooling grooves 22 of the material guiding roller 2. A cooling water tank 4 is fixedly installed at one end of the bottom plate 1 away from the winding roller 3. A cooling roller 5 is arranged on the bracket, and a support mechanism 51 is symmetrically arranged on the cooling roller 5;

[0024] The support mechanism 51 includes a rotating shaft 511 rotatably installed on the bracket, a support plate 512 fixedly installed at one end of the rotating shaft 511, and a torsion spring 513 sleeved on the rotating shaft 511. One end of the support plate 512 away from the rotating shaft 511 is rotatably connected to the cooling roller 5. The two ends of the torsion spring 513 are respectively fixedly connected to the rotating shaft 511 and the bracket.

[0025] In use, when the copper foil is electrolyzed and then wound up, it can first bypass two guide rollers 2 and the end is connected to the winding roller 3. By driving the winding roller 3, the copper foil can be wound up. As the overall thickness of the copper foil wound on the winding roller 3 increases, the cooling roller 5 can always fit against the outer wall of the copper foil under the combined use of the torsion spring 513 and the support plate 512 to achieve cooling of the copper foil.

[0026] Furthermore, rotary joints 21 are fixedly installed at both ends of the guide roller 2 and the cooling roller 5. One end of the cooling water tank 4 is penetrated and installed with a water inlet pipe 41. Connecting pipes 42 are fixedly installed between the water inlet pipe 41 and the two rotary joints 21. A connecting hose 43 is fixedly installed between the water inlet pipe 41 and the other rotary joint 21. The end of the cooling water tank 4 away from the water inlet pipe 41 is penetrated and installed with a main return pipe 44. Return pipes 45 are fixedly installed between the main return pipe 44 and the two rotary joints 21. A return water hose 46 is fixedly installed between the main return pipe 44 and the other rotary joint 21. When the copper foil is on the guide roller 2 and the winding roller 3, the cooling water in the cooling water tank 4 can enter the cooling grooves 22 in the guide roller 2 and the cooling roller 5 through the combined use of the water inlet pipe 41, the connecting pipes 42, the connecting hose 43 and the rotary joint 21, so as to cool and dissipate heat from the copper foil. The used cooling water can enter the cooling water tank 4 through the rotary joint 21, the return pipes 45, the return water hose 46 and the main return pipe 44 for recycling.
