Description

Technical Field

[0001] This utility model relates to the field of graphite film processing technology, and more specifically, to a winding mechanism for a graphite film calender. Background Technology

[0002] Graphite film is a novel thermal conductive and heat dissipation material. It contains super-thermal conductive graphite components, resulting in ultra-high thermal conductivity. Graphite film is a highly crystalline sheet-like material produced by advanced synthesis processes and chemical methods under high-temperature conditions. Its chemical composition is mainly carbon (C), but it has higher thermal and electrical conductivity than metal materials. The biggest advantage of graphite thermal conductive film is that it can dissipate heat evenly along the film plane. Compared with traditional metal materials, its thermal conductivity is 3-5 times that of copper and aluminum.

[0003] In practical use, the vacuum drum position on existing graphite film calenders is fixed, which causes the graphite film to be subjected to uneven adsorption force during calendering. This affects the uniformity of the calendering effect, resulting in defects such as wrinkles, displacement, or uneven thickness of the graphite film, thereby reducing product quality. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a winding mechanism for a graphite film calender to solve the problems mentioned in the background art.

Two connecting seats are fixedly connected to the upper surface of the movable plate. A pull rod is slidably connected inside the connecting seat. A straight rack is welded between the two pull rods. One side of the straight rack is engaged with an arc-shaped rack.

[0008] By adopting the above technical solution, the graphite film can maintain stable tension during unwinding by adjusting the three-axis position and deflection position of the vacuum drum, thus improving the winding quality.

[0010] By adopting the above technical solution, the graphite film can be well bonded to the master roll during unwinding by adjusting the power guide roller, thereby reducing the generation of defects such as bubbles and wrinkles.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. By setting the adjustment component, compared with the existing technology, it can be adjusted according to the width and thickness of different graphite films to ensure that the graphite film can be tightly attached to the vacuum drum during the winding process.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] The embodiments disclosed in this application are as follows: Figure 1-7The diagram shows a winding mechanism for a graphite film calender, comprising a calender 1, a winding roller 2 mounted on one side of the calender 1, an adjusting assembly mounted on one side of the calender 1, an unwinding assembly located in front of the adjusting assembly, a fixed frame 4 mounted above the adjusting assembly, a turntable base 23 fixedly connected to the bottom of the fixed frame 4, a first servo motor 5 fixedly connected to one side of the fixed frame 4, a vacuum drum 6 driven by the output end of the first servo motor 5, the vacuum drum 6 being rotatably connected to the inside of the fixed frame 4, an arc-shaped rack 7 fixedly connected to one side of the fixed frame 4, a first connecting pipe 8 connected to one end of the vacuum drum 6, a vacuum collection box 9 connected to the outside of the first connecting pipe 8, and a device mounted on the outside of the vacuum collection box 9. A vortex blower 10 is provided, and a first connecting pipe 8 passes through the vortex blower 10 and extends into the interior of the vortex blower 10. The output end of the vortex blower 10 is connected to a second connecting pipe 11, and one end of the second connecting pipe 11 is connected to a dust collection box 12. Two air knives 13 are installed inside the dust collection box 12. The graphite film can be pressed down using a tension detection roller 25 and an electric pressure roller, thereby increasing the contact area between the graphite film and the vacuum drum 6. The vacuum drum 6 can generate an adsorption force on the graphite film, making it less likely to slip or wrinkle. The two air knives 13 can blow on both sides of the graphite film, thereby effectively removing dust adhering to the surface of the graphite film and ensuring the quality of winding.

[0024] Reference Figure 3 and 7As shown, the adjustment assembly includes a first electric sliding platform 3, which is slidably connected to one side of the calender 1. A second electric sliding platform 15 is slidably connected to the upper surface of the first electric sliding platform 3, and multiple guide rods 16 are fixedly connected to the upper surface. A movable plate 17 is slidably connected to the upper surface of the calender 1. The bottom end of the turntable base 23 is fixedly connected to the top of the movable plate 17. An electric push rod 18 is hinged to the bottom end of the second electric sliding platform 15. A hinge support 19 is fixedly connected to the output end of the electric push rod 18. The hinge support 19 is fixedly connected to the bottom end of the movable plate 17. Two connecting seats 20 are fixedly connected to the upper surface of the movable plate 17. A pull rod 21 is slidably connected inside the connecting seat 20. A straight rack 22 is welded between the two pull rods 21. One side of the straight rack 22 meshes with an arc-shaped rack 7. The adjustment is achieved by using the first electric sliding platform... Platform 3 can drive the vacuum drum 6 to move in the Z-axis direction, thereby adjusting the vertical height of the vacuum drum 6. By using the second electric sliding platform 15 to slide on the first electric sliding platform 3, the Y-axis direction of the vacuum drum 6 can be adjusted, which makes it easier for the vacuum drum 6 to correct the winding direction of the graphite film. By using the movable plate 17, the vacuum drum 6 can be driven to adjust in the X-direction, so that the vacuum drum 6 can adjust the left and right winding direction of the graphite film. By using the arc angle of the arc rack 7, the straight rack 22 can mesh and drive the fixed frame 4 to deflect when moving. The turntable base 23 can assist the fixed frame 4 to deflect, thereby ensuring that the graphite film can be tightly attached to the vacuum drum 6, which facilitates the control of winding tension, effectively reduces the phenomenon of graphite film slack or deviation during winding, and helps to improve the winding quality.

[0025] Reference Figure 4 and 5 As shown, the unwinding mechanism includes a third electric sliding platform 24, an electric pressure roller mounted above the third electric sliding platform 24, the third electric sliding platform 24 being fixedly connected to the upper surface of the movable plate 17, a tension detection roller 25 mounted above the movable plate 17, a gull support frame 26 slidably connected to one side of the third electric sliding platform 24, a groove 27 opened on one side of the support frame 26, a second servo motor 28 installed inside the support frame 26, a fixed bracket 29 fixedly connected to the output end of the second servo motor 28, the fixed bracket 29 being slidably connected to the inner side of the groove 27, a power guide pressure roller 30 mounted on one side of the fixed bracket 29, and a magnetic powder brake material shaft 31 mounted on one side of the support frame 26. Through the guiding action of the groove 27, the fixed bracket 29 can drive the power guide pressure roller 30 to rotate and offset outside the master roll, and at the same time, the fixed bracket 29 can drive the power guide pressure roller 30 to move up and down, so that the graphite film and the master roll form good contact, reduce the generation of bubbles and wrinkles, and improve the overall quality of the graphite film.

[0026] Working principle of this utility model: This utility model designs a winding mechanism for a graphite film calender, the specific structure of which is shown in the attached instruction manual. Figure 1-7 As shown, in this technical solution, through the cooperation between various structures, when the graphite film needs to be wound up, one end of the graphite film is first passed through the dust collector 12, placed below the electric pressure roller above the third electric sliding platform 24, and wound around the vacuum drum 6, placed below the tension detection roller 25, passed through the calender 1 and wound onto the winding roller 2. Then, the second servo motor 28 is started, which drives the fixed bracket 29 to rotate. The slide groove 27 provides guidance for the fixed bracket 29, so that multiple fixed brackets 29 can drive the power guide pressure roller 30 to rotate on the unwound master roll. At the same time, the fixed brackets 29 can drive the power guide pressure roller 30 to move, so that the power guide pressure roller 30 can better fit on the unwound graphite film. On the graphite film, the take-up roller 2 and the magnetic powder brake shaft 31 are started simultaneously, so that the take-up roller 2 can unwind. At the same time as unwinding, the vortex blower 10 is started. The vortex blower 10 is connected to the vacuum drum 6 through the first connecting pipe 8. The tension detection roller 25 and the electric pressure roller are used to press the graphite film downward. The tension detection roller 25 can detect the unwinding tension of the graphite film, so that the graphite film can adhere to the vacuum drum 6, so that the vacuum drum 6 can adsorb the graphite film with the largest area and prevent the graphite film from shifting during unwinding. The first servo motor 5 is used to drive the vacuum drum 6 to rotate, which helps to assist in the winding of the graphite film. At the same time, two air knives 13 can blow on both sides of the graphite film, thereby effectively removing dust and impurities attached to the surface of the graphite film.

[0027] When unwinding graphite films of different widths, thicknesses, or materials, the first electric sliding platform 3 is activated. The vertical height of the vacuum drum 6 along the Z-axis can be adjusted using the first electric sliding platform 3. The correction direction of the vacuum drum 6 can be adjusted when unwinding graphite films of different materials using the second electric sliding platform 15. The movable plate 17 is moved by the electric push rod 18 through the hinge support 19. Multiple guide rods 16 can provide guidance for the movement of the movable plate 17, so as to adjust the left and right winding direction of the vacuum drum 6.

[0028] When the winding tension is inappropriate and the graphite film tension is loose, pull the lever 21, causing the lever 21 to drive the straight rack 22 to mesh with the arc rack 7. Utilizing the arc angle of the arc rack 7, when the lever 21 pulls the straight rack 22 to mesh with the arc rack 7, it can drive the fixing frame 4 to deflect. The turntable base 23 can assist in supporting the deflection of the fixing frame 4, thereby ensuring that the graphite film can be tightly adhered to the vacuum drum 6.

Other structures can be referred to with ordinary design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

Electrical control components not mentioned in this technical solution are existing technologies and are therefore not shown in the figures and will not be described here.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
