[0045] The present invention will now be described in further detail with reference to the accompanying drawings.

[0046] like Figures 1 to 3 As shown below, the steps and functions of a graphite preparation process will be explained in detail.

[0047] A graphite preparation process, comprising the following steps:

[0048] Step 1: Place the graphite raw material inside the grinding cylinder 11, between the two grinding discs 23;

[0049] Step 2: The two grinding discs 23 rotate to grind the graphite raw material.

[0050] Step 3: The grinding disc 23 uses its conical protrusions to gradually grind the graphite raw material;

[0051] Step 4: When the conical protrusion rotates, it pushes the graphite raw material into the pressure hole 25 through the conical threaded body on it;

[0052] Step 5: The pressing screw shaft 33 installed inside the pressing hole 25 rotates;

[0053] Step 6: The pressure screw shaft 33 rotates to push the graphite raw material in the pressure hole 25 into the pressure mold 45;

[0054] Step 7: The pressing die 45 discharges the graphite raw material through the multiple discharge holes 46 provided thereon;

[0055] Step 8: The graphite raw material discharged from the pressing mold 45 enters the forming mold 64;

[0056] Step 9: The pressing die moves up and down 45 degrees to extrude and shape the graphite raw material.

[0057] like Figures 4 to 14 As shown, in order to facilitate the implementation of a graphite preparation process, a graphite preparation device is designed. The structure and function of the graphite preparation device are described in detail below.

[0058] A graphite preparation apparatus includes a grinding cylinder 11, a connecting pipe 12 fixedly connected to the grinding cylinder 11, two telescopic mechanisms I21 fixedly connected to the grinding cylinder 11, a lifting bracket I22 fixedly connected to the telescopic end of each of the two telescopic mechanisms I21, a grinding disc 23 rotatably connected to each lifting bracket I22, a sliding ring 24 rotatably connected to each grinding disc 23, and a pressing hole 25 provided on each grinding disc 23;

[0059] Both sliding rings 24 are slidably connected inside the grinding cylinder 11. Two grinding discs 23 are distributed vertically in the grinding cylinder 11. The lower end of the upper grinding disc 23 is provided with a conical protrusion, and the upper end of the lower grinding disc 23 is provided with a conical protrusion. Both conical protrusions are provided with conical threaded bodies.

[0060] A power mechanism I for driving the grinding disc 23 to rotate is fixedly connected to the lifting bracket I 22. The power mechanism I is preferably a servo motor.

[0061] A telescopic mechanism II 31 is fixedly connected to the grinding cylinder 11. A lifting bracket II 32 is fixedly connected to the telescopic end of the telescopic mechanism II 31. A pressing screw shaft 33 is rotatably connected to the lifting bracket II 32.

[0062] The pressing screw shaft 33 extends into the two pressing holes 25;

[0063] The lifting bracket II 32 is fixedly connected to a power mechanism II that drives the pressing screw shaft 33 to rotate. The power mechanism II is preferably a servo motor.

[0064] A telescopic mechanism Ⅲ41 is fixedly connected to the grinding cylinder 11. Limiting ring Ⅰ42 and limiting ring Ⅱ43 are fixedly connected to the telescopic end of the telescopic mechanism Ⅲ41. A pressing bracket 44 is slidably connected to the telescopic end of the telescopic mechanism Ⅲ41. The pressing bracket 44 is located between the limiting ring Ⅰ42 and the limiting ring Ⅱ43. A compression spring is fixedly connected between the pressing bracket 44 and the limiting ring Ⅱ43.

[0065] A pressing mold 45 is rotatably connected to the pressing support 44. The pressing mold 45 is provided with multiple discharge holes 46. Each discharge hole 46 has a tapered groove 47 on its upper side. The pressing mold 45 is slidably connected to the pressing hole 25 located on the lower grinding disc 23.

[0066] A feed cylinder 51 is fixedly connected to the connecting pipe 12, a feed pipe 52 is fixedly connected to the feed cylinder 51, a feed screw shaft 53 is rotatably connected inside the feed cylinder 51, and a power mechanism Ⅲ for driving the feed screw shaft 53 to rotate is fixedly connected to the feed cylinder 51. The power mechanism Ⅲ is preferably a servo motor.

[0067] Two telescopic mechanisms IV61 are fixedly connected to the grinding cylinder 11. Telescopic mechanism V62 is fixedly connected to the telescopic ends of the two telescopic mechanisms IV61. Clamping plate 63 is fixedly connected to the telescopic ends of the two telescopic mechanisms V62. A forming mold 64 is clamped between the two clamping plates 63. The forming mold 64 is located below the pressing mold 45.

[0068] When using, such as Figure 4As shown, the graphite raw material is put into the feed cylinder 51 through the feed pipe 52. The power mechanism III is started and the output shaft of the power mechanism III starts to rotate. The output shaft of the power mechanism III drives the feed screw shaft 53 to rotate. When the feed screw shaft 53 rotates, it generates a lateral force. The feed screw shaft 53 pushes the graphite raw material to move in the feed cylinder 51 and pushes the graphite raw material into the grinding cylinder 11.

[0069] When power mechanism I is started, its output shaft begins to rotate, driving the grinding disc 23 to rotate. Figure 5 As shown, the upper and lower grinding discs 23 rotate simultaneously, and the distance between the conical protrusions on the two grinding discs 23 decreases from the outside to the inside, so that the graphite raw material is gradually ground between the two conical protrusions.

[0070] Furthermore, to ensure that the graphite raw material continuously converges from the periphery of the conical protrusion towards its center during the grinding process, and finally grinds between the two conical protrusions, such as... Figure 8 As shown, both conical protrusions are provided with conical threaded bodies. During the rotation of the conical protrusions, the conical threaded bodies come into contact with the graphite material. When the conical threaded bodies rotate, they generate a component force that causes the graphite material to gather from the outside to the middle, causing the graphite material to gradually move from the outside to the inside, thereby completing the gradual grinding. Then, when the conical protrusions rotate, the conical threaded bodies on them push the graphite material into the pressure hole 25.

[0071] Furthermore, the telescopic mechanism I21 can be activated. The telescopic mechanism I21 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I21 drives the grinding disc 23 to move, thereby adjusting the relative distance between the two grinding discs 23 to meet different grinding needs. At the same time, during the grinding process, the telescopic mechanism I21 can also be activated to make the two grinding discs 23 continuously move closer or further away from each other, thereby completing the crushing of graphite raw materials.

[0072] When the graphite raw material enters the pressing hole 25, the power mechanism II is started. The output shaft of the power mechanism II starts to rotate. The output shaft of the power mechanism II drives the pressing screw shaft 33 to rotate. When the pressing screw shaft 33 rotates, it generates a lateral force. The pressing screw shaft 33 pushes the graphite raw material to move downward continuously, so that the graphite raw material continuously enters the discharge hole 46.

[0073] Furthermore, a conical groove 47 is provided on the discharge hole 46, which facilitates the entry of graphite raw materials into the discharge hole 46;

[0074] Furthermore, the telescopic mechanism II 31 can be activated. The telescopic mechanism II 31 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism II 31 drives the lifting bracket II 32 to move. The lifting bracket II 32 drives the pressing screw shaft 33 to move, thereby enabling the pressing screw shaft 33 to move up and down within the pressing hole 25, further pushing the graphite raw material to move.

[0075] like Figure 5 As shown, a forming mold 64 is provided on the lower side of the pressing mold 45. The graphite raw material discharged from the discharge hole 46 enters the forming mold 64. The telescopic mechanism III 41 is activated. The telescopic mechanism III 41 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism III 41 drives the pressing mold 45 to move up and down. The pressing mold 45 moves up and down to reciprocate and extrude the graphite raw material to shape it.

[0076] Furthermore, the pressing mold 45 is slidably connected in the pressing hole 25, so when the grinding disc 23 rotates, it will drive the pressing mold 45 to rotate, and the pressing mold 45 will discharge the graphite raw material while rotating, thus ensuring that the graphite raw material can be evenly entered into the forming mold 64.

[0077] Furthermore, telescopic mechanisms IV61 and V62 can be activated. Telescopic mechanisms IV61 and V62 can be hydraulic cylinders or electric push rods. The telescopic ends of telescopic mechanisms IV61 and V62 drive the clamping plate 63 to move, and the clamping plate 63 drives the forming mold 64 to move, thereby adjusting the position of the forming mold 64.
