Description

Technical Field

[0001] This utility model relates to the field of high-end equipment manufacturing, and in particular to a rapid slitting device for graphene composite carbon fiber film. Background Technology

[0002] Graphene-carbon fiber composite membrane is an advanced material that combines the properties of graphene and carbon fiber. It possesses the high electrical and thermal conductivity of graphene and the high strength and lightweight advantages of carbon fiber, showing broad application prospects in many fields. In the production process of graphene-carbon fiber composite membrane, it needs to be cut into specific shapes according to the needs of different application scenarios to meet the requirements of subsequent processing and use. Precise cutting is a key step in ensuring product quality.

[0003] When traditional die-cutting machines slit graphene composite carbon fiber films, delamination is prone to occur at the cut edges due to the material's properties. To avoid this, it is often necessary to strictly control the cutting speed, reducing the risk of delamination by lowering the speed. However, while this method improves the cutting quality to some extent, it significantly reduces the overall processing efficiency, making it difficult to meet the demands of high-efficiency processing for large-scale production. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of low efficiency in existing die-cutting machines for slitting graphene composite carbon fiber films, and to propose a rapid slitting device for graphene composite carbon fiber films.

[0005] To address the problems existing in the prior art, the present invention adopts the following technical solution: A rapid slitting device for graphene composite carbon fiber film includes a die-cutting machine body and a die-cutting blade mounted on the die-cutting machine body. An adjustable-length bracket is fixedly installed at one end of the die-cutting blade near the feed end. Two limiting rods are vertically slidably installed at the end of the bracket. A weight plate is fixedly installed at the lower end of the limiting rods. A mica heating plate is fixedly installed on the lower surface of the weight plate. The shape of the mica heating plate matches the slitting point of the graphene composite carbon fiber film and is used to preheat the cutting point in advance when the die-cutting blade presses down to slit.

[0006] Preferably, the bracket includes a mounting plate fixedly installed at one end of the die-cutting blade, two fixed rods are fixedly installed on the mounting plate, movable rods are slidably provided on the two fixed rods, the two movable rods are sleeved on the limiting rods, and a driving component for driving the movable rods to move is provided in the middle of the mounting plate.

[0007] Preferably, the driving component includes a bearing fixedly mounted on a mounting plate, a lead screw mounted at the center of the bearing, a connecting block threaded on the lead screw, and the two ends of the connecting block being fixedly connected to the outer wall of the moving rod.

[0008] Preferably, a heater is fixedly mounted on the upper surface of the die-cutting blade, and the wires on the heater are fixedly connected to the mica heating plate.

[0009] Preferably, a spring is fitted on the limiting rod, with the two ends of the spring respectively attached to the lower surface of the moving rod and the upper surface of the weight plate, and a nut is threaded onto the end of the limiting rod.

[0010] Preferably, a temperature sensor is fixedly installed on the upper surface of the weight plate, and the temperature sensor has four detection ends installed on it, which are symmetrically attached to the mica heating plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: In this invention, a precisely positioned mica heating plate is added in front of the die-cutting blade to provide instantaneous local preheating of the cutting path of the graphene composite carbon fiber film before cutting. This preheating process effectively softens the bonding interface at the material cutting point, resulting in less resistance and more uniform stress during die-cutting. This design allows the equipment to significantly increase the operating speed of the die-cutting machine while ensuring high-quality cutting, thus significantly improving production efficiency.

[0017] Example: This example provides a rapid slitting device for graphene composite carbon fiber films. See [link to example]. Figure 1-4 Specifically, it includes a die-cutting machine body 1 and a die-cutting blade 11 mounted on the die-cutting machine body 1. An adjustable length bracket 2 is fixedly installed at one end of the die-cutting blade 11 near the feed. Two limit rods 12 are vertically slidably installed at the end of the bracket 2. A weight plate 13 is fixedly installed at the lower end of the limit rods 12. A mica heating plate 14 is fixedly installed on the lower surface of the weight plate 13. The shape of the mica heating plate 14 matches the cutting point of the graphene composite carbon fiber film and is used to locally heat the cutting point in advance when the die-cutting blade 11 presses down to cut.

[0018] In this embodiment, the die-cutting machine body 1 is existing technology. The die-cutting blade 11 applies pressure through an imprinting plate to cut the graphene composite carbon fiber film into a specific shape. The adjustable support 2 is used to adjust the distance between the mica heating plate 14 and the die-cutting blade 11, thereby controlling the preheating position of the mica heating plate 14 to accurately heat the slit portion of the graphene composite carbon fiber film. The weight plate 13 increases the weight of the mica heating plate 14, allowing it to better contact the graphene composite carbon fiber film during descent and ensuring effective heating. The shape of the mica heating plate 14 matches the slit portion of the graphene composite carbon fiber film, preheating the cut portion when the die-cutting blade 11 presses down, softening the material, resulting in a smoother cut and reduced delamination.

[0019] When the die-cutting blade 11 presses down to prepare to cut the graphene composite carbon fiber film, the bracket 2 drives the limiting rod 12, the weight plate 13 and the mica heating plate 14 to descend. The mica heating plate 14 preheats the cutting area locally. After that, the heated graphene composite carbon fiber film will move directly under the die-cutting blade 11 to perform the cutting action.

[0020] In the specific implementation process, such as Figure 2 and Figure 3 As shown, the bracket 2 includes a mounting plate 21 fixedly installed at one end of the die-cutting blade 11. Two fixed rods 22 are fixedly installed on the mounting plate 21. Moving rods 23 are slidably provided on the two fixed rods 22. The two moving rods 23 are sleeved on the limiting rod 12. A driving component for driving the moving rods 23 to move is provided in the middle of the mounting plate 21.

[0021] In this embodiment, the driving component operates, driving the moving rod 23 to slide on the fixed rod 22. The moving rod 23 drives the limiting rod 12 to move, thereby changing the length of the bracket 2 and realizing the adjustment of the position of the mica heating plate 14.

[0022] In the specific implementation process, such as Figure 2 and Figure 3 As shown, the driving component includes a bearing 3 fixedly mounted on the mounting plate 21, a lead screw 31 mounted at the center of the bearing 3, and a connecting block 32 threaded on the lead screw 31. The two ends of the connecting block 32 are fixedly connected to the outer wall of the moving rod 23.

[0023] In this embodiment, rotating the lead screw 31 causes the thread on the lead screw 31 to engage with the connecting block 32, causing the connecting block 32 to move linearly along the lead screw 31. The connecting block 32 then drives the moving rod 23 to slide on the fixed rod 22, thereby adjusting the length of the bracket 2.

[0024] In the specific implementation process, such as Figure 1 and Figure 2As shown, a heater 4 is fixedly installed on the upper surface of the die-cutting blade 11, and the wire 41 on the heater 4 is fixedly connected to the mica heating plate 14.

[0025] In this embodiment, the heater 4 is fixedly mounted on the upper surface of the die-cutting blade 11, serving as a power source to provide electrical energy to the mica heating plate 14, enabling it to generate heat. The heater 4 is connected to the control system of the die-cutting machine body 1. The wire 41 connects the heater 4 and the mica heating plate 14, transmitting the electrical energy generated by the heater 4 to the mica heating plate 14.

[0026] In the specific implementation process, such as Figure 2 and Figure 3 As shown, a spring 5 is sleeved on the limiting rod 12. The two ends of the spring 5 are respectively attached to the lower surface of the moving rod 23 and the upper surface of the weight plate 13. A nut 51 is threaded onto the end of the limiting rod 12.

[0027] In this embodiment, when the mica heating plate 14 descends and comes into contact with the graphene composite carbon fiber film, the spring 5 is compressed, generating elastic force and playing a buffering role; the nut 51 is fixed to the end of the limiting rod 12 to prevent the moving rod 23 from disengaging.

[0028] In the specific implementation process, such as Figure 2 and Figure 3 As shown, a temperature sensor 6 is fixedly installed on the upper surface of the weight plate 13. The temperature sensor 6 has four detection ends 61 installed on it, and the four detection ends 61 are symmetrically attached to the mica heating plate 14.

[0029] In this embodiment, the temperature sensor 6 is a prior art technology and is connected to the control system of the die-cutting machine body 1. It detects the temperature of the mica heating plate 14 in real time through four detection terminals 61 and feeds the temperature information back to the control system so as to adjust the working state of the heater 4 according to actual needs and control the heating temperature of the mica heating plate 14.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
