[0021] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1 to 4 As shown, an embodiment of the present invention provides a graphite paper cutting device for cutting graphite paper to process the graphite paper into a required size.

[0023] Please refer to Figure 1 、 Figure 2 and Figure 3 The graphite paper cutting device includes a base 1 and a vacuum generator. The base 1 is used to place the graphite paper to be processed. A plurality of parallel cutting grooves 11 are provided on the base 1. The base 1 is also provided with a rotatable movable plate 2 and a first driving component 3 connected to the movable plate 2. A cutting component 4 is provided on the movable plate 2. The cutting component 4 includes a plurality of parallel cutting knives 41 and the cutting knives 41 are provided on a side of the movable plate 2 close to the base 1. The first driving component 3 drives the cutting knives 41 to extend into or out of the cutting groove 11. The base 1 has a vacuum chamber 12 and the base 1 is provided with a plurality of parallel cutting knives 41. Adsorption holes 13 are respectively connected to the vacuum chamber 12, and the adsorption holes 13 are respectively located between two adjacent cutting grooves 11. The base 1 is also provided with a connector 14 connected to the vacuum chamber 12, and the connector 14 is connected to the vacuum generator. The vacuum chamber 12 is evacuated by the vacuum generator to adsorb the graphite paper placed on the base 1 at the adsorption holes 13, and the graphite paper is kept flat on the base 1 to prevent the graphite paper from folding or bending at a small angle. Then, the first driving component 3 drives the movable plate 2 to rotate so that the cutter 41 enters and exits the cutting groove 11 to cut the graphite paper.

[0024] Specifically, the operating steps of performing graphite paper cutting operation using the graphite paper cutting device provided in this embodiment are as follows: first, the graphite paper is placed on the base 1 and placed in a preset position, then the vacuum generator is started to evacuate the vacuum chamber 12 to adsorb the graphite paper on the adsorption hole 13, so that the position of the graphite paper on the base 1 remains stable and flat, and the graphite paper is prevented from folding or bending at a small angle, and then the first driving component 3 is started to drive the movable plate 2 to rotate and drive the cutter 41 to extend into the cutting groove 11, so that the graphite paper can be cut into a certain size. After the cutting is completed, the first driving component 3 drives the movable plate 2 to reset. At this time, the cutter 41 exits the cutting groove 11 driven by the movable plate 2, and then the vacuum generator is turned off to allow the graphite paper to be separated from the adsorption hole 13, and the cut graphite paper can be removed from the base 1. The graphite paper cutting device provided in this embodiment can automatically cut graphite paper and keep the graphite paper flat during the cutting process, preventing the graphite paper from being damaged due to folding or small-angle bending during the cutting process, which is beneficial to improving processing efficiency and ensuring product quality.

[0025] like Figure 2 and Figure 3As shown, the base 1 is further provided with a support frame 5, and the movable plate 2 is provided with a connecting rod 21, one end of which is rotatably connected to the support frame 5. The support frame 5 for mounting the movable plate 2 is provided on the base 1, and the movable plate 2 is rotatably connected to the support frame 5 through the cooperation between the connecting rod 21 provided on the movable plate 2 and the support frame 5, ensuring that the movable plate 2 can flexibly rotate on the base 1.

[0026] In detail, the first driving assembly 3 includes a rotating member 31 rotatably disposed on the support frame 5. The end of the rotating member 31 away from the support frame 5 is rotatably connected to a transmission member 32, and the end of the transmission member 32 away from the rotating member 31 is rotatably connected to the end of the connecting rod 21 away from the support frame 5. When the rotating member 31 rotates on the support frame 5, the rotating member 31 drives the transmission member 32 to move and pushes the movable plate 2 toward the base 1 or pulls the movable plate 2 away from the base 1 through the movement of the transmission member 32, thereby driving the cutter 41 to extend into the cutting groove 11 to cut the graphite paper or driving the cutter 41 to reset, so that the graphite paper cutting device can be operated to continuously perform graphite paper cutting operations.

[0027] like Figure 3 As shown, in this embodiment, the first drive assembly 3 also includes a hydraulic cylinder 33 and a piston rod 34 arranged at the output end of the hydraulic cylinder 33, the end of the hydraulic cylinder 33 away from the piston rod 34 is rotatably connected to the support frame 5, and the end of the piston rod 34 away from the hydraulic cylinder 33 is rotatably connected to the rotating member 31. The hydraulic cylinder 33 drives the piston rod 34 to extend or retract into the hydraulic cylinder 33 to drive the rotating member 31 to rotate, and the rotation of the rotating member 31 drives the movable plate 2 to move. When the hydraulic cylinder 33 drives the piston rod 34 to extend from the hydraulic cylinder 33, the movable plate 2 is driven by the rotating member 31 to approach the base 1. At this time, the cutter 41 extends into the cutting groove 11 and cuts the graphite paper on the base 1. When the hydraulic cylinder 33 drives the piston rod 34 to retract into the hydraulic cylinder 33, the movable plate 2 is driven by the rotating member 31 to move away from the base 1. At this time, the cutter 41 is pushed out of the cutting groove 11 and reset, so as to facilitate the operation of the graphite paper cutting device to perform graphite paper cutting operations.

[0028] Please combine Figure 1 and Figure 3The cutting assembly 4 further includes a fixed blade holder 42 fixedly mounted on the movable plate 2 and two movable blade holders 43 movably mounted on the movable plate 2. The two movable blade holders 43 are respectively located on opposite sides of the fixed blade holder 42. The fixed blade holder 42 and the movable blade holder 43 are respectively provided with the cutters 41. The movable plate 2 is further provided with a second driving assembly 6 that is respectively transmission-connected to the two movable blade holders 43, and the second driving assembly 6 drives the two movable blade holders 43 to simultaneously approach or move away from the fixed blade holder 42. By driving the two movable holders on the movable plate 2 and approaching or moving away from the fixed blade holder 42 through the second driving assembly 6, the spacing between two adjacent cutters 41 can be adjusted, thereby adjusting the size of the graphite paper after the cutters 41 cut the graphite paper. This enables the graphite paper cutting device to cut graphite paper of various sizes to meet the use requirements of different types of products, thereby improving the versatility of the graphite paper cutting device.

[0029] Please refer to Figure 3 The movable plate 2 is provided with two sliding grooves 44 at intervals. The two sliding grooves 44 are respectively located on opposite sides of the fixed knife seat 42, and the two movable knife seats 43 are respectively movably disposed in the sliding grooves 44. The cooperation between the sliding grooves 44 and the movable knife seats 43 guides the movable knife seats 43 to move on the movable plate 2, thereby preventing the movable plate 2 from unexpectedly deflecting when moving. At the same time, the hollowed-out sliding grooves 44 provided on the movable plate 2 can reduce the weight of the movable plate 2, thereby improving the stability of the movable plate 2 when rotating.

[0030] Specifically, the movable plate 2 is further provided with a guide rod 45, the axial direction of which is aligned with the movement direction of the movable knife holder 43. The movable knife holder 43 is provided with a guide hole 46 that cooperates with the guide rod 45. The movable knife holder 43 is retained on the movable plate 2 by the cooperation between the guide holes 46 and the guide rod 45, preventing the movable knife holder 43 from separating from the movable plate 2 during movement, thereby improving the structural stability of the graphite paper cutting device.

[0031] like Figure 3 and Figure 4As shown, the second drive assembly 6 includes a motor 61 and a drive rod 62 disposed at the output end of the motor 61. The drive rod 62 is rotatably disposed on the movable plate 2, and the axial direction of the drive rod 62 is consistent with the movement direction of the movable knife holder 43. The drive rod 62 is provided with two threaded portions 63 with opposite rotation directions, and the movable knife holder 43 is provided with threaded holes 47 that cooperate with the threaded portions 63. When the drive rod 62 is driven by the motor 61 to rotate, the threaded portions 63 cooperate with the threaded holes 47 to drive the movable knife holder 43 to move along the axial direction of the drive rod 62. The two threaded portions 63 on the drive rod 62 have opposite rotation directions, so that the two movable seats are driven by the second drive assembly 6 to move simultaneously in opposite directions by the same distance, so that the spacing between any two adjacent cutters 41 remains consistent, thereby ensuring the same size of the cut graphite paper and ensuring product consistency.

[0032] In detail, the fixed blade holder 42 and the movable blade holder 43 are respectively provided with a slot 48, and the cutter 41 is provided with a block 49 that cooperates with the slot 48. The cutter 41 is connected to the fixed blade holder 42 and the movable blade holder 43 through the cooperation of the block 49 and the slot 48, respectively, so that the connection between the cutter 41 and the fixed blade holder 42 and the movable blade holder 43 is reliable, and the cutter 41 can be easily removed from the fixed blade holder 42 and the movable blade holder 43, so that the cutter 41 can be easily replaced if it is worn after long-term use.

[0033] like Figure 1 and Figure 3 As shown, in this embodiment, the number of the cutting grooves 11 is greater than the number of the cutting blades 41, and the spacing between any two adjacent cutting grooves 11 is equal. When multiple cutting grooves 11 are provided on the base 1 and the second drive assembly 6 is used to adjust the position of the movable blade holder 43, the cutting blades 41 on the movable blade holder 43 are simply adjusted to align with the corresponding cutting grooves 11. This ensures stable operation of the graphite paper cutting device while meeting the requirements for cutting graphite paper of different sizes.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
