Description

Technical Field

[0001] This utility model relates to the field of punching equipment technology, specifically to punching equipment for the production of graphene composite heat dissipation films. Background Technology

[0002] As electronic products become increasingly intelligent and complex, the number of internal components and their integration level are constantly increasing. This trend directly leads to the generation of more heat during operation. If heat is not dissipated in time, it will quickly accumulate and cause high-temperature problems, thereby reducing the performance, reliability, and lifespan of electronic products. Therefore, graphene composite heat dissipation films have emerged.

[0003] In the production of this heat dissipation film, punching equipment is used for precise cutting. For example, a graphene sound film punching device disclosed in CN211267086U includes a base, a vertical plate, a horizontal plate, a die-cutting blade mounting plate, a die-cutting blade, a limiting plate, a slider, a fastening bolt, a baffle, a spring, a column, a handle, a limiting groove, a sliding groove, and a threaded hole. This device has a simple structure and is relatively easy to use. Pressing the handle of the die-cutting mechanism compresses the spring, causing the die-cutting blade to descend. After the die-cutting blade contacts the graphene film on the top surface of the base, it die-cuts the graphene film into a film sheet of the required size. After die-cutting is completed, releasing the handle resets the spring, which in turn resets the die-cutting blade, greatly facilitating the next die-cutting operation.

[0004] While the aforementioned device is suitable for punching graphene composite heat dissipation films, and operation is convenient and efficient—simply pressing the handle is all that's needed to complete the punching process—and the built-in spring mechanism automatically resets the cutter after punching, preparing it for the next use, the mechanical properties of the spring may gradually deteriorate over time, causing it to become unable to quickly and effectively reset the cutter to its initial state. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing a punching and cutting equipment for the production of graphene composite heat dissipation film, thereby ensuring the rebound performance of the spring.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A punching and cutting device for producing graphene composite heat dissipation film includes a punching and cutting device body, a cutter, a vertical rod, a pressure bar and a spring. The outer wall of the vertical rod is provided with a threaded groove, and a nut is threadedly connected to the outer wall of the threaded groove. A retaining sleeve is rotatably connected to the lower end of the nut, and the lower end of the retaining sleeve is fixedly connected to the spring. A fixing component is fixedly connected to the upper surface of the nut.

[0008] Preferably, the fixing component includes a connecting block that is fixedly connected to the nut, and a handle is threadedly connected to one side wall of the connecting block. A vertical groove is provided on one side wall of the vertical rod, and one end of the handle passes through the connecting block and extends into the vertical groove.

[0009] Preferably, the outer wall of the nut is provided with an annular groove, the outer wall of the retainer is threaded with a rotating block, and one side wall of the rotating block is fixedly connected with a pin, one end of the pin passing through the retainer and extending into the annular groove.

[0010] Preferably, a collar is rotatably fitted onto the outer wall of the pin located inside the annular groove.

[0011] Preferably, the upper surface of the punching equipment body is threaded with a threaded post, and a square block is fixedly connected to the upper end of the threaded post. One end of the threaded post penetrates the punching equipment body and abuts against the cutting blade.

[0012] Preferably, the side wall of the square block has a threaded hole that matches one end of the handle.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This utility model uses a nut and a retaining sleeve in conjunction with other structures. When the mechanical properties of the spring decrease due to prolonged use, the nut can be rotated to move the retaining sleeve downwards. The downward-moving retaining sleeve can compress the spring, thereby increasing the spring's elasticity and allowing the spring to quickly move the cutter upwards and reset.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1-4 A punching and cutting equipment for producing graphene composite heat dissipation film includes a punching and cutting equipment body 1, a cutter 2, a vertical rod 3, a pressure bar 4 and a spring 5. The outer wall of the vertical rod 3 is provided with a threaded groove 6, and a nut 7 is threadedly connected to the outer wall of the threaded groove 6. A retaining sleeve 8 is rotatably connected to the lower end of the nut 7, and the lower end of the retaining sleeve 8 is fixedly connected to the spring 5. A fixing component is fixedly connected to the upper surface of the nut 7.

[0022] As can be seen from the above structure, by setting the nut 7 and the retaining sleeve 8 and other structures to work together, when the mechanical performance of the spring 5 decreases due to long-term use, the nut 7 can be rotated, causing the nut 7 to drive the retaining sleeve 8 to move down. The moving retaining sleeve 8 can compress the spring 5, thereby increasing the elasticity of the spring 5, so that the spring 5 can still quickly move the cutter 2 up to reset.

[0023] Furthermore, the fixing component includes a connecting block 9 fixedly connected to the nut 7, and a handle 10 is threadedly connected to one side wall of the connecting block 9. A vertical groove 11 is provided on one side wall of the vertical rod 3. One end of the handle 10 passes through the connecting block 9 and extends into the vertical groove 11. By setting the handle 10, the vertical groove 11 and the connecting block 9 to work together, when one end of the handle 10 is in the vertical groove 11, the handle 10 can block the rotation of the nut 7, thereby stabilizing the position of the nut 7. When rotating the nut 7, first reverse the handle 10 so that the handle 10 is disengaged from the vertical groove 11. Then the nut 7 can be rotated by the handle 10. It should be noted that when stopping the rotation of the nut 7, one end of the handle 10 needs to be rotated to one side of the vertical groove 11 to stop. Then, the one end of the handle 10 can be rotated into the vertical groove 11.

[0024] Furthermore, the outer wall of the nut 7 is provided with an annular groove 12, and the outer wall of the retaining sleeve 8 is threadedly connected with a rotating block 13. A pin 14 is fixedly connected to one side wall of the rotating block 13. One end of the pin 14 passes through the retaining sleeve 8 and extends into the annular groove 12. By setting the rotating block 13 and the pin 14 to work together, the stability of the connection between the retaining sleeve 8 and the nut 7 can be increased, ensuring that the nut 7 can drive the retaining sleeve 8 to move when it moves up and down.

[0025] Furthermore, a collar 15 is rotatably sleeved on the outer wall of the pin 14 located inside the annular groove 12. By setting the collar 15, the friction between the nut 7 and the pin 14 can be reduced when the nut 7 is rotated.

[0026] Furthermore, the upper surface of the punching equipment body 1 is threaded with a threaded post 16, and a square block 17 is fixedly connected to the upper end of the threaded post 16. One end of the threaded post 16 passes through the punching equipment body 1 and abuts against the cutter 2. By setting the threaded post 16, the cutter 2 can be blocked after it moves up to a certain position, so as to stabilize the position of the cutter 2.

[0027] Furthermore, the side wall of the square block 17 is provided with a threaded hole 18 that matches one end of the handle 10; by providing the threaded hole 18, when it is necessary to rotate the square block 17 and the threaded post 16, the handle 10 can be removed and then the handle 10 can be installed on one side of the square block 17, so that the square block 17 and the threaded post 16 can be rotated by the handle 10.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
