[0032] The graphite falls onto the top of the support frame 1, and the graphite is graded by the stepped shape of the support frame 1. The holes on the support frame 1 are arranged in order from small to large, thereby ensuring that graphite of the same particle size enters the same storage frame 26. The electric telescopic rod 34 will drive the sieve plate 30 to move up and down, which is convenient for grading the graphite. If the flake graphite is graded, the flake graphite is graded by the sieve plate 30. Four sieve plates 30 are provided in the device, and the grooves on the four sieve plates 30 are arranged from large to small.

[0033] Working principle: When the device starts working, if the collection frame 23 on the left is used, the prepared graphite is placed in the left collection frame 23 in advance, and the two cylinders 17 on the left are started. The cylinder 17 drives the U-shaped block 21 to move through the connecting plate 19, and the U-shaped block 21 drives the second T-shaped block 20 to move upward. The U-shaped block 21 drives the collection frame 23 to move upward through the second L-shaped plate 36 and the fixed block 22. When the top of the collection frame 23 moves to the highest point beyond the support frame 1, the cylinder 17 is stopped, and the operator swings the collection frame 23 on the left to the right. The collection frame 23 on the left will gradually tilt to the right, and the graphite inside the collection frame 23 on the left will fall into the top of the support frame 1. The sieve plate 30 divides the top of the support frame 1 into four areas. The four areas The hole sizes in the four areas are different. The hole sizes in the four areas are arranged from small to large. The graphite falls into the first area, and the smallest graphite particles will enter the adjacent storage frame 26 through the adjacent holes. After the smallest graphite particles are graded, the first electric telescopic rod 34 is started by an external power supply. The first electric telescopic rod 34 drives the horizontal plate 33 to move upward through the fixed plate 35, and the horizontal plate 33 drives the connecting plate 32 to move upward. The connecting plate 32 drives the vertical rod 31 to move upward, and the vertical rod 31 drives the sieve plate 30 to move upward. The sieve plate 30 enters the fixed frame 29, and the graphite in the first area will fall into the second area. The smaller graphite particles will fall into the adjacent storage frame 26 through the holes in the second area. After the smaller graphite particles are graded, the second electric telescopic rod 34 is started by an external power supply, and the second electric telescopic rod 34 drives the horizontal plate 33 to move upward through the fixed plate 35, and the horizontal plate 33 drives the connecting plate 32 to move upward, and the connecting plate 32 drives the vertical rod 31 to move upward, and the vertical rod 31 drives the sieve plate 30 to move upward, and the sieve plate 30 enters the fixed frame 29, and the graphite in the second area will fall into the third area, and the larger graphite particles will fall into the adjacent storage frame 26 through the holes in the third area. After the larger graphite particles are graded, the third electric telescopic rod 34 is started by an external power supply, and the third electric telescopic rod 34 drives the horizontal plate 33 to move upward through the fixed plate 35, and the horizontal plate 33 carries The movable connecting plate 32 moves upward, the connecting plate 32 drives the vertical rod 31 to move upward, the vertical rod 31 drives the sieve plate 30 to move upward, the sieve plate 30 enters the fixed frame 29, the graphite in the third area will fall into the fourth area, the largest graphite particles will fall into the adjacent storage frame 26 through the holes in the fourth area, so as to classify graphite of different particle sizes. When it is necessary to classify the flake graphite, the sieve plate 30 is extended, and the flake graphite is classified through the grooves on the sieve plate 30. The grooves on the four sieve plates 30 are arranged from large to small. When the graphite particles are classified, if it is necessary to speed up the efficiency of the graphite particle classification, the motor 11 is started, and the motor 11 drives the transmission rod 12 to rotate.The transmission rod 12 drives the limit plate 13 to rotate forward and reversely. The motor 11 is a servo motor. The limit plate 13 drives the support frame 1 to swing left and right, thereby accelerating the efficiency of graphite particle classification. If the collection frame 23 on the left cannot be used, the motor 11 will rotate the support frame 1 90 degrees, and rotate the collection frame 23 originally located below to the right direction, so that the device can be used normally. When the support frame 1 swings left and right, the support frame 1 will drive the spring 5 to move and stretch through the support plate 6, thereby driving the swing plate 3 to swing and adjust, so as to cooperate with the swing direction of the support frame 1. When the storage frame 26 needs to be taken out, the elastic inclined plate 24 is pulled to move the L-shaped baffle 25 from the surface of the adjacent storage frame 26, so that the storage frame 26 can be taken out.
