Description

Technical Field

[0001] This utility model relates to the field of graphite film processing technology, specifically a graphite film cutting device. Background Technology

[0002] Graphite film is a novel thermally conductive and heat-dissipating material. Containing super-thermally conductive graphite, it boasts extremely high thermal conductivity. Graphite film is a highly crystalline, sheet-like material produced under high-temperature conditions using advanced molding processes and chemical methods. Its chemical composition is primarily carbon, but it exhibits higher thermal and electrical conductivity than metallic materials. The greatest advantage of graphite thermal conductive film is its ability to uniformly dissipate heat along its plane. Compared to traditional metallic materials, its thermal conductivity is 3-5 times that of copper and aluminum. It rapidly converts point heat sources into surface heat sources through uniform heat conduction along the film's direction. It also possesses high chemical stability, good corrosion resistance and high-temperature resistance, excellent thermal and electrical conductivity, and low thermal resistance. Due to its good flexibility, it can be bent repeatedly and adhered to any uneven surface. During the production process of graphite film, it needs to be cut into different sizes according to actual requirements.

[0003] For example, application number CN202222934986.2 relates to a hydraulic graphite film cutting machine, including a fixed base. A support frame is fixedly installed on the front of the fixed base, and a lifting mechanism is movably installed inside the support frame. A fixing mechanism is movably installed on the top of the fixed base. This hydraulic graphite film cutting machine, by setting up the lifting and fixing mechanisms, allows the graphite film to be positioned at the top of the fixed base during use. The output shaft of the second hydraulic lifting rod drives the lifting rod downwards. Simultaneously, under the combined action of the two mechanisms, the first and second fixing plates move downwards inside the fixed base until they are parallel to the top of the fixed base, thus pressing the graphite film. This fixing mechanism, which can fix the graphite film, effectively prevents the graphite film from sliding during the cutting process.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problems of existing cutting devices that fail to firmly fix the graphene film during use, resulting in easy slippage of the graphene film, low stability, and poor cutting effect, the L-shaped clamps, although adjustable in height to accommodate graphene films of different thicknesses and ensure a smooth cut surface, cannot adjust the spacing of the L-shaped clamps, which greatly reduces the practicality of the aforementioned equipment. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a graphite film cutting device that has the advantage of easy spacing adjustment. This solves the problem that although the L-shaped clamps can be adjusted in height to accommodate graphite films of different thicknesses and ensure a smooth cutting surface, the width specifications of graphite films are also diverse, but the spacing of the L-shaped clamps cannot be adjusted, thus greatly reducing the practicality of the aforementioned device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a graphite film cutting device, comprising a worktable, a cutting device, an L-shaped clamp, and a hydraulic cylinder. The right side of the cutting device is fixedly connected to the left side of the worktable. Slide grooves are provided on both the front and rear sides of the top of the worktable. The surface of the L-shaped clamp is slidably connected to the inner wall of the slide groove. The hydraulic cylinder is located at the bottom of the worktable. An installation plate is fixedly connected to the output end of the hydraulic cylinder. The bottom of the L-shaped clamp is slidably connected to the top of the installation plate. An adjustment mechanism is fixedly connected to the front side of the top of the installation plate. A sliding connection assembly is fixedly connected to the bottom of the L-shaped clamp. Stabilizing components are provided at the four corners of the top of the installation plate.

[0007] As a preferred embodiment of this utility model, the adjusting mechanism includes a motor, the bottom of which is fixedly connected to the front side of the top of the mounting plate, a bidirectional screw is fixedly connected to the output end of the motor, a folding frame is provided on the top of the mounting plate, the inner wall of the folding frame is threadedly connected to both ends of the surface of the bidirectional screw, and a fixing plate is fixedly connected to both sides of the folding frame, and the two outer sides of the fixing plate are fixedly connected to the bottom of the inner side of the L-shaped clamp.

[0008] As a preferred embodiment of this utility model, the sliding connection assembly includes a trapezoidal block, the top of which is fixedly connected to the bottom of the L-shaped clamping rod, and trapezoidal grooves are provided on both sides of the top of the mounting plate, with the surface of the trapezoidal block slidingly connected to the inner wall of the trapezoidal groove.

[0009] As a preferred embodiment of this utility model, the stabilizing component includes a through groove, which is formed at the four corners of the top of the mounting plate. A vertical rod is slidably connected to the inner wall of the through groove, and the top of the vertical rod is fixedly connected to the four corners of the bottom of the workbench.

[0010] As a preferred embodiment of this utility model, a U-shaped frame is fixedly connected to the bottom of the hydraulic cylinder, and the two sides of the top of the U-shaped frame are fixedly connected to the two sides of the bottom of the worktable.

[0011] As a preferred embodiment of this invention, both ends of the surface of the bidirectional screw are movably connected to support blocks via pins, and the bottom of the support blocks is fixedly connected to both sides of the top of the mounting plate.

[0012] As a preferred embodiment of the present invention, a distance groove is provided on the front side of the top of the workbench, and a plurality of distance grooves are provided and are distributed at equal intervals.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting a sliding groove, allows for the adjustment of the spacing of the L-shaped clamps when the spacing needs to be adjusted. The adjustment mechanism drives the L-shaped clamps to move symmetrically within the sliding groove, thereby adjusting the spacing of the L-shaped clamps. This is suitable for clamping graphite films of different widths. It solves the problem that while the height of the L-shaped clamps can be adjusted to accommodate graphite films of different thicknesses and ensure a smooth cut surface, the spacing of the L-shaped clamps cannot be adjusted due to the diverse widths of graphite films. This significantly reduces the practicality of the aforementioned equipment and achieves the effect of easy spacing adjustment.

[0015] 2. This utility model, by setting an adjustable distance mechanism, allows the user to start the motor when the two L-shaped clamping rods need to move symmetrically. This drives the bidirectional screw to rotate, causing the folding frame to fold under the drive of the bidirectional screw. This, in turn, pushes the fixing plate to move symmetrically inward or outward, thus enabling the L-shaped clamping rods to move symmetrically and adjust the distance to fit the clamping and limiting of graphite films of different widths.

[0016] 3. By setting up a sliding connection component, when the L-shaped clamp rod slides symmetrically along the sliding groove under the folding motion of the folding frame, the trapezoidal block at the bottom of the L-shaped clamp rod slides in the trapezoidal groove. Then, through the cooperation of the trapezoidal block and the trapezoidal groove, a connection is established between the L-shaped clamp rod and the mounting plate, and the L-shaped clamp rod can still slide. This allows the hydraulic cylinder to still control the height of the L-shaped clamp rod to adapt to graphite films of different thicknesses. Attached Figure Description

[0021] 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.

[0022] like Figures 1 to 3 As shown, the present invention provides a graphite film cutting device 2, including a worktable 1, a cutting device 2, an L-shaped clamping rod 3, and a hydraulic cylinder 4. The right side of the cutting device 2 is fixedly connected to the left side of the worktable 1. Slide grooves 5 are provided on both the front and rear sides of the top of the worktable 1. The surface of the L-shaped clamping rod 3 is slidably connected to the inner wall of the slide groove 5. The hydraulic cylinder 4 is located at the bottom of the worktable 1. The output end of the hydraulic cylinder 4 is fixedly connected to a mounting plate 6. The bottom of the L-shaped clamping rod 3 is slidably connected to the top of the mounting plate 6. An adjusting mechanism 7 is fixedly connected to the front side of the top of the mounting plate 6. A sliding connection assembly 8 is fixedly connected to the bottom of the L-shaped clamping rod 3. Stabilizing components 9 are provided at the four corners of the top of the mounting plate 6.

[0023] refer to Figure 2 and Figure 3 The adjusting mechanism 7 includes a motor 71. The bottom of the motor 71 is fixedly connected to the front side of the top of the mounting plate 6. A bidirectional screw 72 is fixedly connected to the output end of the motor 71. A folding frame 73 is provided on the top of the mounting plate 6. The inner wall of the folding frame 73 is threadedly connected to both ends of the surface of the bidirectional screw 72. Fixing plates 74 are fixedly connected to both sides of the folding frame 73. The outer sides of the fixing plates 74 are fixedly connected to the bottom of the inner side of the L-shaped clamp 3.

[0024] As a technical optimization of this utility model, by setting the distance adjustment mechanism 7, when the user needs the two L-shaped clamping rods 3 to move symmetrically, the motor 71 is started, which drives the bidirectional screw 72 to rotate, so that the folding frame 73 is driven by the bidirectional screw 72 to fold, thereby pushing the fixing plate 74 to move symmetrically inward or outward, thus enabling the L-shaped clamping rods 3 to move symmetrically and adjust the distance to adapt to the clamping and limiting of graphite films of different widths.

[0025] refer to Figure 3 The sliding connection assembly 8 includes a trapezoidal block 81, the top of which is fixedly connected to the bottom of the L-shaped clamping rod 3. Trapezoidal grooves 82 are provided on both sides of the top of the mounting plate 6, and the surface of the trapezoidal block 81 is slidably connected to the inner wall of the trapezoidal groove 82.

[0026] As a technical optimization of this utility model, by setting the sliding connection component 8, when the L-shaped clamping rod 3 slides symmetrically along the sliding groove 5 under the folding movement of the folding frame 73, the trapezoidal block 81 at the bottom of the L-shaped clamping rod 3 slides in the trapezoidal groove 82. Then, through the cooperation of the trapezoidal block 81 and the trapezoidal groove 82, a connection is established between the L-shaped clamping rod 3 and the mounting plate 6, and the L-shaped clamping rod 3 can still slide, so that the hydraulic cylinder 4 can still control the height of the L-shaped clamping rod 3 to adapt to graphite films of different thicknesses.

[0027] refer to Figure 3 The stabilizing component 9 includes a through groove 91, which is opened at the four corners of the top of the mounting plate 6. The inner wall of the through groove 91 is slidably connected to a vertical rod 92, and the top of the vertical rod 92 is fixedly connected to the four corners of the bottom of the workbench 1.

[0028] As a technical optimization of this utility model, by setting a stabilizing component 9, when the hydraulic cylinder 4 pushes the mounting plate 6 to rise and fall, and the height of the L-shaped clamping rod 3 is adjusted, the through grooves 91 at the four corners of the mounting plate 6 will slide along the upright rod 92. Thus, through the cooperation between the through grooves 91 and the upright rod 92, a fixed horizontal path is provided for the rise and fall of the mounting plate 6, thereby preventing the output end of the hydraulic cylinder 4 from shaking and causing the horizontal position of the L-shaped clamping rod 3 to change, thus affecting the position of the graphite film.

[0029] refer to Figure 2 The bottom of the hydraulic cylinder 4 is fixedly connected to the U-shaped frame 10, and the top two sides of the U-shaped frame 10 are fixedly connected to the bottom two sides of the worktable 1.

[0030] As a technical optimization of this utility model, by setting up the U-shaped bracket 10, a stable installation base is provided for the hydraulic cylinder 4, which enhances the stability of the hydraulic cylinder 4 during operation and prevents the hydraulic cylinder 4 from shaking due to lack of fixation.

[0031] refer to Figure 3 Both ends of the surface of the bidirectional screw 72 are movably connected to support blocks 11 by shaft pins, and the bottom of the support blocks 11 is fixedly connected to the two sides of the top of the mounting plate 6.

[0032] As a technical optimization of this utility model, by setting a support block 11, when the motor 71 drives the bidirectional screw 72 to rotate, the support block 11 restricts the axial displacement of the bidirectional screw 72 through the shaft pin, allowing it to rotate only around the shaft pin, thus preventing the bidirectional screw 72 from bending or deviating due to force, thereby making the rotation of the bidirectional screw 72 more stable.

[0033] refer to Figure 1 The front side of the top of the workbench 1 is provided with a distance groove 12, and there are several distance grooves 12 that are evenly distributed.

[0034] As a technical optimization of this utility model, by setting the distance groove 12, a visual reference is provided for adjusting the distance between the two L-shaped clamping rods 3, which makes it easier for users to quickly and accurately adjust the distance between the L-shaped clamping rods 3 to the target value, reducing the number of trial and error in the adjustment process and thus improving the user's work efficiency.

[0035] The working principle and usage process of this utility model are as follows: When the user needs to cut the graphite film, first place the graphite film on the worktable 1, then start the motor 71 to drive the bidirectional screw 72 to rotate, causing the folding frame 73 to be driven by the bidirectional screw 72 to undergo a folding motion, which in turn pushes the fixing plate 74 to move symmetrically inward or outward, thus enabling the L-shaped clamping rod 3 to move symmetrically. Subsequently, the L-shaped clamping rod 3 begins to slide within the slide groove 5 to adjust the spacing. At the same time, the trapezoidal shape at the bottom of the L-shaped clamping rod 3... Block 81 slides within the trapezoidal groove 82 until the inner side of the L-shaped clamp 3 contacts the graphite film, limiting the two sides of the graphite film. Then, the hydraulic cylinder 4 can be activated to pull the mounting plate 6 down. Subsequently, the L-shaped clamp 3, in cooperation with the trapezoidal block 81 and the trapezoidal groove 82, will descend together with the mounting plate 6, until the right angle of the L-shaped clamp 3 presses on the graphite film. At this point, the cutting device 2 can be activated to cut the graphite film, thus providing the advantage of easy spacing adjustment.

[0036] In summary, the graphite film cutting device 2, by setting a sliding groove 5, activates the distance adjustment mechanism 7 when it is necessary to adjust the spacing of the L-shaped clamping rods 3, driving the L-shaped clamping rods 3 to move symmetrically within the sliding groove 5, thereby achieving the adjustment of the spacing of the L-shaped clamping rods 3. Therefore, it is suitable for clamping graphite films of different widths. This solves the problem that although the height of the L-shaped clamping rods can be adjusted to accommodate graphite films of different thicknesses and ensure a smooth cutting surface, the spacing of the L-shaped clamping rods cannot be adjusted due to the diverse width specifications of graphite films, which greatly reduces the practicality of the aforementioned equipment.
