[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this embodiment can be combined with each other. The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 5 As shown, the purpose of this embodiment is to provide a graphite raw material crushing device, including a feeding chamber 3 and a crushing chamber 2 fixedly installed on the lower surface of the feeding chamber 3, a separation chamber 1 fixedly installed on the lower surface of the crushing chamber 2, two crushing mechanisms 4 are rotatably installed in the crushing chamber 2, and a gap is left between the two crushing mechanisms 4 for allowing the crushed graphite powder raw material to pass through, and the two crushing mechanisms 4 are used for crushing, and a screening mechanism 6 is fixedly installed in the separation chamber 1, and the screening mechanism 6 is used to screen the graphite powder raw material that is not completely crushed.

[0028] The crushing mechanism 4 includes a shaft 401, which is rotatably installed in the crushing chamber 2. A roller 402 is fixedly installed on the shaft 401, and a crushing tool 403 is fixedly installed on the side wall of the roller 402. The two crushing tools 403 are squeezed against each other to crush the graphite powder raw material. By providing the shaft 401, the roller 402 rotates along with the shaft 401, and because the roller 402 is provided, the crushing tools 403 can be distributed in a circular array on the outer surface of the roller 402. The motor 5 is started, and the output shaft of the motor 5 drives the shaft 401 and the roller 402 to rotate, and the two crushing tools 403 are squeezed against each other to crush the graphite powder raw material.

[0029] Among them, the side wall of the crushing chamber 2 is fixedly installed with a motor 5, and the shaft 401 passes through the side wall of the crushing chamber 2 and is coaxially connected to the output shaft of the motor 5. By providing a motor 5, and the output shaft of the motor 5 is coaxially connected to the shaft 401, the motor 5 is driven, and the output shaft of the motor 5 drives the two rollers 402 to rotate, and the two crushing tools 403 are squeezed against each other to crush the graphite powder raw material.

[0030] Furthermore, the separation chamber 1 is a cylindrical structure with a flattened upper surface, and a discharge port 8 is provided at the bottom end of the separation chamber 1, which is located directly below the two crushing mechanisms 4. A collection box 7 is placed in the separation chamber 1, and the collection box 7 is located on the side and lower side of the screening mechanism 6. Because the separation chamber 1 is connected with the crushing chamber 2, the graphite powder raw material with a suitable diameter falls into the rotating shaft 601 through the axial hole 603, and the axial hole 603 passes through the surface of the rotating shaft 601. The graphite powder raw material will reach the separation chamber 1 through the axial hole 603 and be discharged from the separation chamber 1 through the discharge port 8, while the graphite powder raw material with a larger diameter will pass between two adjacent limit plates 602 and then be poured into the collection box 7, and then the graphite powder raw material in the collection box 7 will be thrown into the discharge chamber 3 for secondary grinding to achieve a better crushing effect.

[0031] It should be noted that a chamber door is provided on the back of the separation chamber 1, and the internal collecting box 7 can be taken out by opening the chamber door, so that the graphite powder raw material in the collecting box 7 can be thrown into the feeding chamber 3 for secondary grinding.

[0032] Furthermore, the screening mechanism 6 includes a rotating shaft 601, which is rotatably mounted in the separation chamber 1. A through hole is provided on the side wall of the rotating shaft 601, and the through hole is used to output the completely crushed graphite powder raw material. A plurality of shaft holes 603 are provided on the side wall of the rotating shaft 601. A plurality of limiting plates 602 are fixedly mounted on the side wall of the rotating shaft 601. Two adjacent limiting plates 602 just limit the graphite powder raw material with a suitable diameter to between the two limiting plates 602. When the graphite powder raw material enters the separation chamber 1 from the crushing chamber 2, the graphite powder raw material passes through the shaft. The graphite powder raw materials with a smaller diameter than the shaft hole 603 fall into the rotating shaft 601 through the shaft hole 603, and the graphite powder raw materials with a larger diameter than the shaft hole 603 continue to stay between two adjacent limiting plates 602. As the rotating shaft 601 rotates, a motor is fixedly installed on the side wall of the separation chamber 1, and the output shaft of the motor is coaxially connected with the rotating shaft 601. The graphite powder raw materials between the two adjacent limiting plates 602 will be poured into the collecting box 7, and then the graphite powder raw materials in the collecting box 7 will be thrown into the feeding chamber 3 for secondary grinding.

[0033] When the utility model is used in practice, a larger volume of graphite powder raw material is thrown into the crushing chamber 2 through the feeding chamber 3, and the motor 5 is driven. The output shaft of the motor 5 drives the two rollers 402 to rotate, and the two crushing cutters 403 are squeezed against each other to crush the graphite powder raw material. Because the separation chamber 1 is connected with the crushing chamber 2, the graphite powder raw material with a suitable diameter falls into the rotating shaft 601 through the axial hole 603, and the surface of the rotating shaft 601 passes through the axial hole 603. The graphite powder raw material will reach the separation chamber 1 through the axial hole 603 and be discharged from the separation chamber through the feeding port 8, while the graphite powder raw material with a larger diameter will pass between two adjacent limit plates 602 and fall into the collecting box 7. The graphite powder raw material in the collecting box 7 is thrown into the feeding chamber 3 for secondary grinding to achieve a better crushing effect.
