Description

Technical Field

[0001] The utility model relates to the technical field of graphite paper production, in particular to a calendering device for producing flexible graphite paper. Background Art

[0002] Graphite paper is a thin sheet product made of graphite material with excellent thermal conductivity, electrical conductivity, high temperature resistance, corrosion resistance and other properties. It is widely used in high-tech fields such as the communications industry, mobile phones, and computers as a thermal conductive and heat dissipation material, as well as in sealing and electrical conductivity. The main raw materials of graphite paper are graphite powder or graphite blocks. These raw materials need to be screened and purified to ensure their quality and purity.

[0003] For example, the patent application number disclosed on the China Patent Network is: 202122593135.1, and the patent name is: A new type of flexible graphite paper calendering device, comprising a base, two groups of first fixed seats and two groups of second fixed seats are fixedly installed on the top of the base, guide rollers are rotatably connected between the two groups of the first fixed seats, two groups of calendering rollers are rotatably connected between the two groups of the second fixed seats, and two groups of motors are fixedly installed on the surface of one group of the second fixed seats. Through the setting of the cleaning component, when the graphite paper passes inside the protective shell, the two groups of brushes will clean the upper and lower parts of the graphite paper at the same time. At the end of the graphite paper calendering, the dirt on the top of the graphite paper will fall into the collection box under the action of gravity, and the dirt on the bottom of the graphite paper will fall into the collection box in real time, thereby realizing the cleaning of the dirt on the surface of the graphite paper.

[0004] However, the existing calendering device directly hinges the graphite paper to the inside of the machine by pulling it with a pressure roller. During the pulling process, the graphite paper is subjected to uneven tension, resulting in changes in width. This change makes it impossible for the graphite paper to fully fit the pressure roller during the calendering process, thereby affecting the uniformity and quality of the calendering. Moreover, the longitudinal wrinkles generated in the graphite paper during the pulling process not only affect the appearance, but more importantly, they will destroy the continuity and integrity of the graphite paper.

[0005] Therefore, it is necessary to design and transform the calendering equipment used in the production of flexible graphite paper. Utility Model Content

[0034] As a technical optimization solution of the present invention, the graphite paper 3 transported on the surface of the support rod 6 is stretched by the combination of the bracket 8, the cross plate 9, the connecting frame 10 and the guide roller 11.

The side of the bracket 8 close to the rocker arm 5 is fixedly connected to the surface of the sleeve plate 15.

[0036] As a technical optimization solution of the present invention, the combined design of the vertical plate 12, the rotating wheel 13, the sliding rod 14 and the sleeve plate 15 on the outside of the rocker arm 5 provides a flexible adjustment space for the bracket 8 and the stretch structure 7. By rotating the rotating wheel 13, the sliding rod 14 and the sleeve plate 15 can be driven to slide on the guide rod 16, thereby adjusting the position of the bracket 8 and the stretch structure 7 to adapt to graphite paper 3 of different sizes and thicknesses, thereby improving the flexibility and applicability of the equipment.

[0037] refer to Figure 4 The outer side of the rocker arm 5 is fixedly connected with a guide rod 16 , and the sleeve plate 15 is sleeved on the surface of the guide rod 16 and is slidably connected with the guide rod 16 .

[0041] refer to Figure 3 The front of the horizontal plate 9 is fixedly connected to a carrying frame 18 , and the bottom of the carrying frame 18 is fixedly connected to the top of the connecting frame 10 .

[0042] As a technical optimization solution of the present invention, the supporting frame 18 fixedly connected to the front of the transverse plate 9 is fixedly connected to the top of the connecting frame 10, providing stable support for the stretch structure 7.

[0043] The working principle and use process of the present invention are as follows: in the production process of flexible graphite paper, the graphite paper 3 is first transported to the inside of the frame 1 of the calendering equipment. Rocker arms 5 are set on both sides of the frame 1. The rocker arms 5 are movably connected to the frame 1 through pins and can swing flexibly. The rocker arms 5 are away from one side of the frame 1 and are also movably connected to the support rods 6 through pins. The graphite paper 3 is hung on the surface of the support rods 6 and is slidably connected to the support rods 6. As the equipment is started, the support rods 6 begin to drive the graphite paper 3 to move toward the pressure roller 2. The support rods 6 can support the graphite paper 3 and improve the transportation stability. In order to ensure that the graphite paper 3 remains flat during transportation and avoid wrinkles, the equipment sets a stretching structure 7 on the surface of the rocker arms 5. The structure 7 mainly includes a bracket 8 arranged on the outside of the rocker arm 5, and a transverse plate 9 is fixed on the bracket 8. The bottom of the transverse plate 9 is connected to the connecting frame 10, and the guide roller 11 is movably connected inside the connecting frame 10. When the graphite paper 3 slides on the support rod 6, its top will contact the outer surface of the guide roller 11. The guide roller 11 slightly stretches and flattens the graphite paper 3 to ensure that the paper can smoothly enter the pressing roller 2. During the transportation of the graphite paper 3, the graphite paper 3 can use the sliding force to push the support rod 6 to rotate. The support rod 6 uses the bevel gear 17 to drive the wheel 13 to rotate. The wheel 13 drives the slide rod 14 to slide inside the sleeve 15. The sleeve 15 is squeezed and uses the bracket 8 and the transverse plate 9 to drive the guide roller 11 to move horizontally, further improving the stretching effect.

[0044] In summary, the calendering equipment for producing flexible graphite paper achieves stable transportation and calendering of graphite paper 3 through the combination of the frame 1, the pressure roller 2 and the support structure 4. The design of the support structure 4 enables the graphite paper 3 to be hung on the support rod 6 and slide, avoiding longitudinal wrinkles on the surface caused by direct pulling, thereby ensuring the flatness and quality of the graphite paper 3 during the calendering process.
