Description

Technical Field

[0001] This utility model relates to the field of graphene heating plate production technology, specifically to a plate cutting device for graphene heating plate production. Background Technology

[0002] In the production process of graphene heating plates, plate cutting is a crucial step connecting raw material processing and subsequent molding. A cutting device is needed to precisely cut rolled or large-sized graphene plates into blanks that meet production specifications. The cutting efficiency and accuracy directly affect the production rhythm and product quality of the heating plates. Existing technologies, such as the cutting device disclosed in CN 117428846 A, achieve stable fixing of the plate during cutting through the cooperation of a limiting mechanism, a pressing positioning mechanism, and an adsorption positioning mechanism, reducing bending and improving positioning stability to a certain extent, thus meeting the basic cutting accuracy requirements. However, this type of device has significant efficiency shortcomings: its cutting of graphene sheets relies on single clamping and positioning. After each cut, the cut blank must be manually removed, re-clamped, and the sheet to be cut must be manually pushed to the cutting position. Especially in mass production scenarios, repeated clamping and manual feeding not only increase the labor intensity of operators but also cause significant interruptions in the cutting process, making continuous operation impossible. Therefore, its efficiency needs improvement. Therefore, developing a graphene heating plate production sheet cutting device that can achieve automatic feeding and continuous cutting without repeated clamping has become an urgent need to solve efficiency bottlenecks and improve large-scale production capabilities. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a graphene heating plate cutting device for production, so as to solve the problem that the cutting of graphene plates in the prior art relies on single clamping and positioning. After each cutting, the cut blank needs to be manually removed, re-clamped and fixed, and the plate to be cut also needs to be manually pushed to the cutting position. Especially in the case of mass production, repeated clamping and manual feeding not only increase the labor intensity of operators, but also cause obvious interruptions in the cutting process, making it impossible to achieve continuous operation.

[0004] This utility model is achieved through the following technical solution: A sheet cutting device for graphene heating plate production includes a frame and support legs mounted on the bottom of the frame. A support frame is fixedly installed inside the frame, and a cutting blade holder is movably installed inside the support frame via a cylinder. A cutting blade is installed on the bottom surface of the cutting blade holder. A support platform is fixedly installed inside the frame corresponding to the position of the cutting blade, and a blade groove is provided on the support platform. Conveying mechanisms are symmetrically arranged on both sides of the support platform inside the frame. A fixed-length component is installed on the frame corresponding to one of the conveying mechanisms. The fixed-length component includes a pair of round rods symmetrically rotated on the side wall of the frame. A sleeve is slidably installed on the round rod, and a positioning bolt is threaded on the sleeve. A support rod is fixedly installed on one side wall of the sleeve, and a baffle is fixedly installed on the support rod. The baffle is located above the conveying mechanism. A flipping component is also provided on the frame to provide power for the two round rods to flip synchronously away from the conveying mechanism.

[0005] Furthermore, a pointer is provided on the other side of the sleeve, and a scale line is provided on the top surface of the frame corresponding to the pointer position.

[0006] Furthermore, the flipping assembly includes a support plate, a drive shaft, a first gear, a second gear, a third gear, and a rack. The support plates are symmetrically fixed on both sides of the frame sidewall. The drive shaft is rotatably mounted on the support plate, and the first gear and the second gear are fixedly mounted on the drive shaft. The third gear is coaxially fixed on a round rod and meshes with the first gear. A rack is meshed on one side of the second gear, and the rack is slidably mounted on the sidewall of the support frame.

[0007] Furthermore, connecting rods are symmetrically fixed at both ends of the tool holder. The connecting rods pass through the side wall of the support frame and are mounted on movable plates. The straight rack is fixedly mounted on the movable plates. Limiting rails are symmetrically fixed on both sides of the movable plates on the side wall of the support frame.

[0008] Furthermore, a correction component is also provided on the frame corresponding to another conveying mechanism. The correction component includes a correction plate movably mounted above the conveying mechanism and an adjustment unit for adjusting the distance between the two correction plates.

[0009] Furthermore, multiple rollers are rotatably mounted on the sides of both of the correction plates.

[0010] Furthermore, the adjustment unit includes a bidirectional lead screw, a movable plate, and a connecting rod. The bidirectional lead screw is rotatably installed inside the frame and located below the conveying mechanism. The bidirectional lead screw is driven by a motor installed outside the frame. Screw sleeves are symmetrically installed on the two threaded parts of the bidirectional lead screw. The screw sleeves are fixedly embedded in the movable plate. The movable plate is connected to the correction plate through the connecting rod. The movable rod has a "U" shaped structure and is installed through the side wall of the frame.

[0011] Furthermore, guide plates are symmetrically fixed on the frame, and through holes are provided on the guide plates for the connecting rods to pass through.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention significantly improves the continuity and efficiency of sheet metal cutting through "automated linkage design," adapting to the needs of large-scale production. The conveying mechanism enables automatic and continuous conveying of sheets without manual pushing; the fixed-length component blocks the sheet metal to trigger cutting through a baffle, and works in conjunction with the flipping component to link with the cutting action—the baffle automatically flips to avoid the already cut sheet metal when the cutter descends, and the baffle resets synchronously when the cutter resets, realizing a cyclical automation of "conveyance-fixed length-cutting-avoidance." This solves the efficiency shortcomings of traditional devices that require manual feeding and repeated clamping, reduces manual intervention, and significantly increases the cutting volume per unit time.

[0013] In this invention, the length-fixing component uses a pointer and scale lines to intuitively and accurately adjust the cutting length, avoiding errors from manual estimation. The correction component uses a bidirectional lead screw to synchronously adjust the spacing between the correction plates, adapting to different widths of materials and limiting conveyor offset. The roller design reduces friction and prevents scratches on the materials. The precise alignment of the cutting blade and the cutting groove ensures thorough cutting, while the limiting rails, guide plates, and other structures ensure stable movement of all components without deviation. The overall design balances automation efficiency with precise cutting, effectively reducing dimensional deviation rates and providing high-quality material cutting support for graphene heating plate production.

The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

Detailed Implementation

[0017] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0018] Please see Figure 1-6 This utility model provides a technical solution for a graphene heating plate production sheet cutting device: A graphene heating plate production sheet cutting device includes a frame 1 and support legs 2 installed on the bottom surface of the frame 1. The frame 1 provides an overall support frame for the entire cutting device, bearing core components such as cutting, conveying, and length setting, ensuring the stability of each component. The support legs 2 support the frame 1 to maintain a horizontal height, preventing the frame 1 from directly contacting the ground and causing moisture or wear, while reserving space below for installation to adapt to production line layout requirements.

[0019] A support frame 3 is fixedly installed inside the frame 1. A cutting blade holder 5 is movably mounted inside the support frame 3 via a cylinder 4. A cutting blade 6 is mounted on the bottom surface of the cutting blade holder 5. A support platform 7 is fixedly installed inside the frame 1 corresponding to the position of the cutting blade 6. A blade groove 8 is provided on the support platform 7. The support frame 3 provides mounting support for the cylinder 4 and the cutting blade holder 5, ensuring structural stability during cutting. The cylinder 4 provides driving force to drive the cutting blade holder 5 and the cutting blade 6 to reciprocate up and down, realizing the cutting of the sheet material. The cutting blade 6 directly contacts the graphene sheet material to complete the cutting action. The support platform 7 supports the sheet material to be cut, ensuring that the sheet material is flat and does not bend during cutting. The blade groove 8 corresponds to the cutting blade 6, preventing the cutting blade 6 from directly contacting the support platform 7 during cutting and causing blade damage, while ensuring thorough cutting.

[0020] Inside the frame 1, symmetrical conveying mechanisms 9 are arranged on both sides of the support platform 7. The conveying mechanism 9 is an existing modular component that can realize the automatic and continuous conveying of graphene sheets without manual pushing, thus solving the defects of low efficiency and intermittent cutting of manual feeding in the background technology and providing core power for continuous cutting.

[0021] A fixed-length assembly is installed on the frame 1 at one of the conveying mechanisms 9. The fixed-length assembly includes a pair of round rods 10 symmetrically rotated on the side wall of the frame 1. A sleeve 11 is slidably mounted on the round rod 10. A positioning bolt 12 is threaded onto the sleeve 11. A support rod 13 is fixedly mounted on one side wall of the sleeve 11. A baffle 14 is fixedly mounted on the support rod 13. The baffle 14 is located above the conveying mechanism 9. The round rod 10 provides the basis for the sliding and rotation of the sleeve 11. The sleeve 11 can slide along the round rod 10 to adjust the distance between the baffle 14 and the cutting blade 6, adapting to different specifications of sheet metal. The positioning bolt 12 is locked after the sleeve 11 is adjusted to fix the relative position of the sleeve 11 and the round rod 10, so as to avoid the deviation of the baffle 14 during cutting and thus the fixed length error. The support rod 13 connects the sleeve 11 and the baffle 14 to ensure that the height of the baffle 14 is adapted to the plate on the conveying mechanism 9. The baffle 14 is used to block the plate during conveying. When the end of the plate contacts the baffle 14, the sensor (not shown in the figure) senses the position and starts cutting through the controller. The conveying mechanism stops conveying the plate, thus realizing fixed length cutting and solving the problem of needing to manually measure the fixed length in the background technology.

[0022] The frame 1 is also equipped with a flipping component, which provides power for the two round rods 10 to flip synchronously away from the conveying mechanism 9. The flipping component can drive the baffle 14 to flip upward when the cutter 6 is cutting downward, so that the cut board can continue to be conveyed forward with the conveying mechanism, avoiding obstruction of the conveying of the cut board. After the cutting is completed, the baffle 14 is reset to continue to block the next section of board, realizing continuous cutting cycle without manual intervention, and solving the efficiency shortcoming of repeated clamping in the background technology.

[0023] Please see Figure 4 and Figure 5 A pointer 15 is also provided on the other side of the sleeve 11, and a scale line 16 is provided on the top surface of the frame 1 corresponding to the pointer 15. The pointer 15 and the scale line 16 work together to visually read the distance between the baffle 14 and the cutter 6, accurately adjust the cutting length, avoid manual estimation errors, and improve the length setting accuracy.

[0024] Please see Figure 4 and Figure 5The flipping assembly includes a support plate 17, a transmission shaft 18, a first gear 19, a second gear 20, a third gear 21, and a rack 22. The support plate 17 is symmetrically fixed on both sides of the support frame 3 on the sidewall of the frame 1. The transmission shaft 18 is rotatably mounted on the support plate 17, and the first gear 19 and the second gear 20 are fixedly mounted on the transmission shaft 18. The third gear 21 is coaxially fixed on the round rod 10 and meshes with the first gear 19. The rack 22 is meshed on one side of the second gear 20 and slides on the sidewall of the support frame 3. The support plate 17 fixes the position of the transmission shaft 18 to ensure stable gear transmission. When the rack 22 moves downward, it meshes and drives the second gear 20 to rotate, causing the transmission shaft 18 and the first gear 19 to rotate synchronously. The first gear 19 meshes and drives the third gear 21 to rotate, thereby causing the round rod 10 and the baffle 14 to flip upward, so that the baffle 14 can automatically avoid collisions.

[0025] Please see Figure 5 and Figure 6 The cutting blade holder 5 is symmetrically fixed with connecting rods 23 at both ends. The connecting rods 23 pass through the side wall of the support frame 3 and are mounted with movable plates 24. The rack 22 is fixedly mounted on the movable plate 24. The side wall of the support frame 3 is also symmetrically fixed with limit rails 25 on both sides of the movable plate 24. The connecting rods 23 move up and down synchronously with the cutting blade holder 5, causing the movable plate 24 to slide along the limit rails 25. The movable plate 24 drives the rack 22 to move synchronously. No additional driving element is needed to drive the rack 22. This makes the cutting action linked with the flipping action of the baffle 14, ensuring timing synchronization and avoiding cutting failure due to misalignment. The limit rails 25 restrict the movement direction of the movable plate 24 to prevent the movable plate 24 from shifting and causing misalignment between the rack 22 and the second gear 20.

[0026] Please refer to the figure. A correction component is also provided on the frame 1 at the position corresponding to another conveying mechanism 9. The correction component includes a correction plate 26 movably disposed above the conveying mechanism 9 and an adjustment unit for adjusting the distance between the two correction plates 26. The correction plate 26 can restrict the conveying direction of the graphene sheet to prevent the sheet from shifting during conveying, which would cause deviation in the cutting size and improve the cutting accuracy. The adjustment unit can be adapted to graphene sheets of different widths, taking into account both versatility and precision.

[0027] Please see Figure 1-3 Multiple rollers 27 are rotatably mounted on the sides of both correction plates 26. The rollers 27 convert the sliding friction between the correction plates 26 and the plate into rolling friction, reducing the resistance of the plate conveying, preventing the plate from being scratched or jammed due to friction, and ensuring the smoothness of continuous conveying.

[0028] Please see Figure 3 and Figure 6The adjustment unit includes a bidirectional lead screw 28, a movable plate 30, and a connecting rod 31. The bidirectional lead screw 28 is rotatably mounted inside the frame 1 and located below the conveying mechanism 9. The bidirectional lead screw 28 is driven by a motor 29 located outside the frame 1. Sleeves are symmetrically installed on the two threaded portions of the bidirectional lead screw 28, and these sleeves are fixedly embedded in the movable plate 30. The movable plate 30 is connected to the correction plate 26 via the connecting rod 31. The movable plate 30 has a "U"-shaped structure and extends through the side wall of the frame 1. The motor 29 drives the bidirectional lead screw 28 to rotate, and the sleeves on the bidirectional lead screw 28 cause the two movable plates 30 to move closer or further away synchronously. The movable plates 30, through the connecting rod 31, cause the two correction plates 26 to adjust their spacing synchronously, achieving rapid adaptation to plates of different widths without manual adjustment, thus improving efficiency. The "U"-shaped movable plate 30 ensures that the connecting rod 31 is subjected to balanced force, preventing the correction plate 26 from shifting.

[0029] Please see Figure 2 and Figure 6 The frame 1 is also symmetrically fixed with guide plates 32. The guide plates 32 have through holes for the connecting rods 31 to pass through. The guide plates 32 provide sliding guidance for the two connecting rods 31, restricting the connecting rods 31 to move only in the horizontal direction, and ensuring that the spacing of the correction plates 26 is accurately adjusted.

[0030] Before use, according to the cutting specifications of the graphene board, loosen the positioning bolt 12, slide the sleeve 11 along the round rod 10, adjust the distance between the baffle 14 and the cutter 6 by the pointer 15 and the scale line 16, and after determining the fixed length, tighten the positioning bolt 12; at the same time, start the motor 29, drive the bidirectional lead screw 28 to rotate, drive the movable plate 30 and the connecting rod 31 to adjust the distance between the two correction plates 26 to match the width of the board. After the device is started, the conveying mechanism 9 conveys the graphene sheet towards the cutter 6. When the end of the sheet contacts the baffle 14, the sensor sends a signal to the controller, which starts the cylinder 4. The cylinder 4 pushes the cutting blade holder 5 and the cutter 6 downward. The cutter 6 completes the cutting of the sheet in the blade groove 8 of the support platform 7. At the same time, the cutting blade holder 5 drives the connecting rod 23 and the movable plate 24 to move downward. The movable plate 24 drives the rack 22 to slide down along the side wall of the support frame 3. The rack 22 meshes and drives the second gear 20 to rotate. The transmission shaft 18 and the first gear 19 rotate synchronously. The first gear 19 meshes and drives the third gear 21 and the round rod 10 to rotate. The baffle 14 flips upward to avoid the movement. After cutting, cylinder 4 drives the cutting blade 6 and cutting blade holder 5 to return to their original position. Connecting rod 23 and movable plate 24 drive rack 22 to slide upwards. Through gear transmission, round rod 10 and baffle 14 return to their original position above conveying mechanism 9. At the same time, the cut sheet is sent away by the other side conveying mechanism 9, and the uncut sheet continues to be conveyed to contact baffle 14, triggering the next cutting cycle. The entire process requires no manual clamping, feeding, or adjustment, realizing automatic continuous fixed-length cutting of graphene sheets. This solves the efficiency shortcomings caused by repeated clamping and manual feeding in the background technology and adapts to the needs of large-scale production.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
