Description

Technical Field

[0001] This utility model relates to the field of graphite material processing technology, and in particular to a graphite sheet cutting device. Background Technology

[0002] Graphite flakes are sheet-like materials made from natural graphite, artificial graphite, or graphite composites as substrates through processes such as machining, chemical treatment, or physical deposition. Natural graphite substrates are often made from high-purity flake graphite, which is then exfoliated into multi-layered sheet structures through machining processes such as grinding and calendering, retaining the excellent thermal and electrical conductivity of natural graphite.

[0003] In the existing technology, graphite flakes are prone to edge chipping, delamination or overall breakage during the cutting process due to their brittleness and weak interlayer bonding. Traditional cutting methods mostly rely on manual operation or general cutting equipment, and lack special positioning and fixing structures for the characteristics of graphite flakes. This results in defects such as poor positioning accuracy and uneven force during cutting, making it difficult to ensure the consistency of cutting quality. At the same time, the processing efficiency is low and cannot meet the needs of mass production. Utility Model Content

[0004] In view of the above-mentioned problems with cutting, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a graphite sheet cutting device, comprising two bodies, with a conveyor belt for transporting graphite sheets installed between the two bodies. One of the bodies has a notch at its top, and a fixed plate is fixedly installed inside the notch. Two meshing rotating gears are rotatably connected to one side of the fixed plate. A fixed column is fixedly connected to the end face of the rotating gears and is eccentrically arranged thereto. A sleeve rod is fitted on the circumference of the fixed column. A cylinder is fitted on the end of the sleeve rod near the conveyor belt. A sliding block is fixedly connected to the end of the cylinder near the fixed plate. A cutting blade is fixedly connected to the end of the sliding block near the conveyor belt. Multiple evenly distributed moving columns are installed on the end of the sliding block near the conveyor belt. Silicone pads are fixedly connected to the ends of the two sets of moving columns that are close to each other.

[0006] In a preferred embodiment of the graphite sheet cutting device of this utility model, multiple moving columns are distributed in a mirror image around the cutting blade, and multiple evenly distributed slots are opened at the bottom of the sliding block. The slots are slidably connected to the circumferential surface of the moving columns, and a spring is connected between the top of the slot and the top of the moving column.

[0007] In a preferred embodiment of the graphite sheet cutting device of this utility model, two evenly distributed rectangular blocks are fixedly connected to one end of the fixed plate near the rotating gear. The inner wall of the rectangular blocks is slidably connected to the surface of the sliding block. Two conveyor belts are arranged between the two rectangular blocks, and the rectangular blocks and the conveyor belts are perpendicular to each other.

[0008] In a preferred embodiment of the graphite sheet cutting device of this utility model, a drive motor is fixedly connected to the top end of the machine body near the rotating gear, a main shaft is fixedly connected to the output end of the drive motor, the circumferential surface of the main shaft is fixedly connected to the inner ring surface of one of the rotating gears, and a rotating rod fixedly connected to the fixed plate is rotatably connected to the inner ring surface of the other rotating gear.

[0009] As a preferred embodiment of the graphite sheet cutting device of this utility model, the sleeve rod has a first straight groove at one end near the sliding block, which is slidably connected to the circumferential surface of the cylinder; the sleeve rod has a second straight groove at one end near the rotating gear; and the sleeve rod has a circular through hole at one end away from the sliding block.

[0010] As a preferred embodiment of the graphite sheet cutting device of this utility model, the inner wall of the circular through hole is rotatably connected to a connecting column that is fixedly connected to one end of the fixed plate, the circumferential surface of the fixed column is slidably connected to the second straight groove, and the bottom end of the machine body is fixedly connected to a support foot that contacts the ground.

[0011] The beneficial effects of this utility model are: Two meshing rotating gears drive a fixed column and a drive sleeve to reciprocate around a connecting column. The sleeve then drives a sliding block to move precisely up and down along a rectangular block via a cylinder. In the initial downward movement of the sliding block, the rapid transmission of the dual gears causes the sleeve and sliding block to descend quickly, allowing the silicone pad to rapidly contact the graphite sheet and complete the pre-positioning, reducing positioning time. Simultaneously, the moving column compresses a spring to generate constant flexible pressure. Furthermore, the moving column is mirror-distributed around the cutting blade, uniformly pre-pressing the area around the cutting zone, effectively offsetting cutting stress and suppressing interlayer peeling and edge chipping of the sheet. The spring pressure is adaptable to different thicknesses. Thin sheets do not require frequent parameter adjustments. During the descent phase from when the sliding block contacts the silicone pad to when the cutting blade completes the cut, and during the brief period before the cutting blade rises and resets after cutting, the dual-gear transmission, through the cooperation of the fixed column and the sleeve rod, forms a slow movement trajectory. This slow movement process ensures that the cutting blade cuts into and leaves the thin sheet at a stable speed, avoiding the thin sheet chipping caused by a sudden increase in cutting stress due to excessively fast movement. At the same time, it ensures that the pre-compression fixing effect of the silicone pad on the thin sheet remains stable, further ensuring that the thin sheet does not wobble during the cutting process, improving cutting quality, facilitating maintenance, and adapting to the needs of industrial mass production.

Detailed Implementation

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0019] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 This is the first embodiment of the present invention, which provides a graphite sheet cutting device, including two machine bodies 1, and a conveyor belt 2 for transporting graphite sheets installed between the two machine bodies 1. One of the machine bodies 1 has a notch at its top, and a fixing plate 3 is fixedly installed in the notch. Two meshing rotating gears 5 are rotatably connected to one side of the fixing plate 3. A fixing post 6 is fixedly connected to the end face of the rotating gear 5 and is eccentrically arranged with it. A sleeve rod 7 is sleeved on the circumference of the fixing post 6. A cylinder 10 is sleeved on the end of the sleeve rod 7 near the conveyor belt 2. A sliding block 9 is fixedly connected to the end of the cylinder 10 near the fixing plate 3. A cutting blade 12 is fixedly connected to the end of the sliding block 9 near the conveyor belt 2. A plurality of evenly distributed moving posts 13 are installed on the end of the sliding block 9 near the conveyor belt 2. A silicone pad 14 is fixedly connected to the end of each set of moving posts 13 that is close to each other.

[0020] Multiple movable columns 13 are distributed in a mirror image around the cutting blade 12. The bottom end of the sliding block 9 has multiple evenly distributed slots. The slots are slidably connected to the circumferential surface of the movable columns 13. A spring 15 is connected between the top of the slot and the top of the movable column 13.

[0021] Two evenly distributed rectangular blocks 11 are fixedly connected to one end of the fixed plate 3 near the rotating gear 5. The inner wall of the rectangular block 11 is slidably connected to the surface of the sliding block 9. Two conveyor belts 2 are set between the two rectangular blocks 11, and the rectangular blocks 11 and the conveyor belts 2 are perpendicular to each other.

[0022] During use, when the conveyor belt 2 transports the graphite sheet to be cut between two rectangular blocks 11, the sliding block 9 moves vertically downward along the inner wall of the rectangular block 11. The rectangular block 11 guides the sliding block 9 to ensure a stable movement trajectory. During this process, multiple moving columns 13 at the bottom of the sliding block 9 move downward synchronously, first causing the silicone pad 14 at the bottom to contact the surface of the graphite sheet on the conveyor belt 2.

[0023] As the sliding block 9 continues to move downward, the moving column 13 slides upward in the groove at the bottom of the sliding block 9. The spring 15 between the top of the groove and the top of the moving column 13 is compressed. Since multiple moving columns 13 are distributed in a mirror image with the cutting blade 12 as the center, the silicone pad 14 will be evenly attached to the surface of the graphite sheet with the cutting blade 12 as the center and apply pressure. The elasticity of the spring 15 keeps the pressure of the silicone pad 14 on the sheet constant. This process achieves pre-compacting and fixing around the cutting area of ​​the graphite sheet, avoiding edge chipping and delamination caused by loosening or uneven force during subsequent cutting.

[0024] After the silicone pad 14 stabilizes and fixes the graphite sheet, the cutting blade 12 at the bottom of the sliding block 9 moves down to contact and cut into the graphite sheet, completing the cutting action. During the cutting process, the silicone pad 14 maintains constant pressure on the sheet to ensure that the sheet does not shift, thereby ensuring cutting accuracy. After the cutting is completed, the sliding block 9 moves upward, and the spring 15 rebounds to push the moving column 13 and the silicone pad 14 back to their original positions, releasing the fixation on the sheet. The cut sheet is then conveyed to the next process by the conveyor belt 2. Example 2

[0025] Reference Figures 1-3 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a drive motor is fixedly connected to the top end of the body 1 near the rotating gear 5, and a main shaft 16 is fixedly connected to the output end of the drive motor. The circumferential surface of the main shaft 16 is fixedly connected to the inner ring surface of one of the rotating gears 5, and a rotating rod 17 fixedly connected to the fixed plate 3 is rotatably connected to the inner ring surface of the other rotating gear 5.

[0026] The sleeve rod 7 has a first straight groove at one end near the sliding block 9, which is slidably connected to the circumferential surface of the cylinder 10. The sleeve rod 7 has a second straight groove at one end near the rotating gear 5, and a circular through hole at one end away from the sliding block 9.

[0027] The inner wall of the circular through hole is rotatably connected to a connecting column 8 that is fixedly connected to one end of the fixed plate 3. The circumferential surface of the fixed column 6 is slidably connected to the second straight groove. The bottom end of the machine body 1 is fixedly connected to a support foot 4 that is in contact with the ground.

[0028] During use, the drive motor at the top of the machine body 1 is started. The output end of the drive motor drives the main shaft 16 to rotate. The circumferential surface of the main shaft 16 is connected to the inner ring surface of one of the rotating gears 5, thereby driving the rotating gear 5 to rotate around the axis of the main shaft 16. Since the two rotating gears 5 mesh with each other, when the first rotating gear 5 rotates, it will drive the second rotating gear 5 to rotate synchronously in the opposite direction. The two rotating gears 5 rotate in opposite directions to ensure that the subsequent transmission actions are coordinated.

[0029] Each rotating gear 5 has a fixed post 6 fixed on its end face away from the center. A sleeve rod 7 is fitted on the circumferential surface of the fixed post 6. The fixed post 6 can slide in the second straight groove at one end of the sleeve rod 7. When the rotating gear 5 rotates, the fixed post 6 moves in a circular motion with the gear. Since the fixed post 6 is off from the center of the rotating gear 5, its circular motion drives the sleeve rod 7 to reciprocate around the connecting post 8 as the center. The connecting post 8 is fixed on the fixed plate 3. The end of the sleeve rod 7 away from the sliding block 9 is rotatably connected to the connecting post 8 through a circular through hole. The connecting post 8 provides the rotation fulcrum for the sleeve rod 7.

[0030] The sleeve rod 7 has a first straight groove at one end near the conveyor belt 2. A cylinder 10 is slidably connected in the groove. The cylinder 10 is fixedly connected to the sliding block 9. When the sleeve rod 7 reciprocates, it pushes or pulls the cylinder 10 through the first straight groove, thereby driving the sliding block 9 to move up and down along the inner wall of the rectangular block 11. This transmission process converts the rotational motion of the drive motor into the linear reciprocating motion of the sliding block 9, realizing the up and down cutting action of the cutting blade 12 and the pre-pressing and resetting action of the silicone pad 14. No additional drive components are required, the structure is simple and the transmission efficiency is high.

[0031] The remaining structure is the same as that in Example 1.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
