[0030] The crushing assembly 12 includes a mounting plate 13 and a limiting block 17. One end of the mounting plate 13 and the limiting block 17 are fixedly connected to the outside of the processing box 1. A second motor 14 is fixedly connected to the top of the mounting plate 13. The output shaft of the second motor 14 is fixedly connected to a first driving bevel gear 15. One end of the first driving bevel gear 15 is fixedly connected to a fixed shaft 16. One end of the fixed shaft 16 passes through the limiting block 17 and is fixedly connected to a second driving bevel gear 18, ensuring the stability of the fixed shaft 16 during rotation. Both the first driving bevel gear 15 and the second driving bevel gear 18 are meshed with driven bevel gears 19 on one side. The crushing assembly 12 also includes a fixing rod 20. One end of the fixing rod 20 rotates on the inner wall of the processing box 1, and the other end of the fixing rod 20 passes through the processing box 1 and is fixed. A crushing roller 21 is fixedly sleeved on the outside of a fixed rod 20 connected to one end of the driven bevel gear 19. Multiple sets of protrusions 22 are fixedly connected to the outer wall of the crushing roller 21. A baffle 23 is fixedly connected to the inner wall of the processing box 1.

[0031] Working principle: First, the second motor 14 is started, which drives the first active bevel gear 15 to rotate. The first active bevel gear 15 drives the second active bevel gear 18 to rotate through the fixed shaft 16. At the same time, the first active bevel gear 15 and the second active bevel gear 18 drive the driven bevel gear 19 to rotate. The driven bevel gear 19 drives the crushing roller 21 to rotate through the fixed rod 20. The crushing roller 21 drives the protrusion 22 to rotate, which crushes the 3D printing waste material into smaller particles, making it easier for subsequent processing and improving the processing capacity. The crushed 3D printing waste material falls into the screening box 3. Then, the first motor 5 is started, which drives the active eccentric wheel 6 to rotate. The active eccentric wheel 6 drives the driven eccentric wheel 8 to rotate through the connecting shaft 7. The rotation of the active eccentric wheel 6 and the driven eccentric wheel 8 drives the fixed plate 11 to move up and down. The fixed plate 11 drives the slider 10 to slide inside the slide groove 9. The slider 10 drives the screening box 3 to move up and down, thereby causing the screening box 3 to vibrate and separate particles that meet the particle size range, improving product quality.
