[0026] Example 3

[0027] Please see Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 8 and Figure 9As shown, based on Embodiment 1 and Embodiment 2, a toggle assembly 6 is provided inside the crushing chamber 2. The toggle assembly 6 includes a reciprocating screw 61 rotatably mounted on the inner wall of the crushing chamber 2. A movable plate 63 with a toggle rod 64 is threaded through the reciprocating screw 61. The toggle rod 64 is fixedly mounted on the side of the movable plate 63 near the grinding cylinder 1. The toggle rod 64 serves to toggle large pieces of graphite inside the crushing chamber 2, facilitating reciprocating movement and minimizing the possibility of large pieces of graphite clogging the crushing chamber 2. A guide rod 611 is slidably mounted through the other end of the movable plate 63. 611 serves as a guide and balance plate 63. A third motor 65 is fixedly installed on one side of the grinding cylinder 1, driving the reciprocating screw 61 to rotate. A transport auger 68 is rotatably installed inside the transport cylinder 3, transporting the ground graphite powder. A heating rod 67 is fixedly installed on the outer surface of the transport cylinder 3, drying the graphite powder. A powder outlet cylinder 66 is connected to the end of the transport cylinder 3 away from the grinding cylinder 1. A blower 610 is fixedly installed on the bottom surface of the powder outlet cylinder 66, cooperating with... The powder discharge cylinder 66 facilitates the dispersion of graphite powder and allows for the classification and screening of graphite powder by size within the cylinder, simplifying the sorting and discharge operation. A temperature controller 69 is fixedly installed on one side of the powder discharge cylinder 66. The temperature controller 69 is electrically connected to the heating rod 67 and the heating wire 47, facilitating the control of the heating rod 67 and the heating wire 47 to heat the conveying cylinder 3 and the first grinding disc 41. A fourth motor 612 is fixedly installed on the side of the conveying cylinder 3 away from the powder discharge cylinder 66. The output end of the fourth motor 612 slides through the conveying cylinder 3 and is fixedly installed on the conveying auger 68. The output end of the machine 65 slides through the crushing box 2 and is fixedly installed on the reciprocating screw 61. The two ends of the guide rod 611 are fixedly installed on the inner wall of the crushing box 2. A baffle plate 62 is fixedly installed on the inner wall of the crushing box 2 away from the grinding cylinder 1. The baffle plate 62 serves to prevent graphite from damaging the reciprocating screw 61, facilitates material feeding and prevents blockage of the crushing box 2, facilitates heating and drying of the ground graphite, facilitates transportation and unloading, improves the material feeding capacity of the device, improves the heating and drying effect of the device, and improves the classification and collection capacity of the device.

[0028] The working principle of this invention is as follows: When using the device, firstly, large pieces of graphite material are placed into the crushing chamber 2, and then the crushing chamber 2 is started to crush the large pieces of graphite. The crushed graphite blocks fall onto the first grinding disc 41 through the protective plate 54. At the same time, the rotating column 43 is started to drive the second grinding disc 42 to contact the first grinding disc 41. Then, the second motor 53 and the first motor 411 are started, so that the output end of the second motor 53 drives the mounting frame 55 and the unblocking auger 52 to rotate synchronously. At the same time, the mounting frame 55 drives the cleaning brush 56 and the third grinding roller 5 8. Rolling within the conical groove, the cleaning plate 59 is simultaneously pressed tightly against the third grinding roller 58 by the telescopic rod 510 and spring 511. Then, the scraper 57 is intermittently activated, scraping the graphite material initially ground by the first grinding disc 41 into the feed inlet. It undergoes fine grinding between the first and second grinding discs 41 and 42, simultaneously causing the output of the first motor 411 to drive the rotating column 43 to rotate within the grinding cylinder 1. This rotating column 43 also causes the second grinding disc 42 to rotate against the first grinding disc 41. The rotating column 43 drives the first grinding roller 45 to roll on the inner wall of the grinding cylinder 1 via the first electric telescopic rod 44. Simultaneously, the rotating column 43 drives the tilting plate 49 to flip on the bottom wall of the grinding cylinder 1. Then, the rotating column 43 drives the second grinding roller 48 to perform a second grinding operation on the flipped graphite. At the same time, the temperature controller 69 is activated, controlling the heating wire 47 to preheat the graphite on the first grinding disc 41. Then, the temperature controller 69 controls the heating rod 67 to heat and dry the conveyor cylinder 3. Finally, the third motor 6 is activated. 5. The output end of the third motor 65 drives the reciprocating screw 61 to rotate. At the same time, the reciprocating screw 61 drives the moving plate 63 to slide on the guide rod 611. Simultaneously, the moving plate 63 drives the actuating rod 64 to reciprocate within the crushing box 2. Then, the fourth motor 612 is started, and the output end of the fourth motor 612 drives the conveying auger 68 to rotate within the conveying cylinder 3, transporting the ground graphite powder in the conveying cylinder 3 into and out of the powder cylinder 66. At the same time, the blower 610 is started to disperse the powdered graphite, making it easier to classify and collect through the powder outlet cylinder 66.

All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
