The processing mechanism 20-5 is arranged on the inner wall of the outer wall 20-6 and is located below the mixing mechanism 20-4.

[0045] The working principle of the above technical solution is as follows: during the waste recycling process, the crushed waste in the waste collecting box 19 is transported to the screening mechanism 20-3 through the second waste leakage hole 20-1 of the waste processing device 20, and the outer wall 20-6 separates the screening mechanism 20-3, the mixing mechanism 20-4, and the processing mechanism 20-5 from the outside world. The first shaft motor 20-2 drives the screening mechanism 20-3 to operate to further grind and screen the waste. The screened waste powder falls into the mixing mechanism 20-4, and the mixing mechanism 20-4 rotates to drive the waste powder, so that the waste powder is evenly transported to the processing mechanism 20-5 for reprocessing, thereby realizing the recycling of waste.

[0046] Beneficial effects of the above technical solution: Through the design of the above structure, this embodiment provides a specific structure of the waste treatment device 20, the screening mechanism 20-3 further crushes and grinds the crushed waste and screens the waste at the same time, the mixing mechanism 20-4 rotates and mixes the screened waste powder, and the evenly mixed waste powder is transported to the processing mechanism 20-5 for reprocessing, and then the waste is reprocessed into usable 3D printing raw materials, thereby realizing the recycling of waste, reducing economic losses, reducing waste pollution, and protecting the environment.

[0047] See also Figure 4-5 In one embodiment, a cleaning mechanism 21 is disposed on the upper surface of the printing table 1, and the cleaning mechanism 21 includes a cleaning cotton 21-1, a support rod 21-2, a sliding plate 21-3, a sliding rail 21-4, and a removable baffle 21-5;

[0049] The working principle of the above technical solution is as follows: after the waste on the surface of the printing table 1 is put into the first waste leakage hole 15, the operator can push the support rod 21-2 of the cleaning mechanism 21 to make the support rod 21-2 reciprocate along the slide rail 21-4 through the slide plate 21-3, and the cleaning cotton 21-1 reciprocates on the surface of the printing table 1 driven by the support rod 21-2 to keep the printing table 1 clean.

When the removable baffle 21-5 is removed, the support rod 21-2 and the sliding plate 21-3 can be removed along the slide rail 21-4, and then the cleaning cotton 21-1 on the support rod 21-2 can be cleaned to achieve recycling, with a simple structure, convenient operation, and easy disassembly and cleaning.

The push rod 20-32 is arranged below the sleeve 20-38. The push rod is connected to the cylinder. The sleeve 20-38 A spring 20-37 is arranged above the outer wall 20-6, and the upper end of the spring 20-37 is connected to the outer wall 20-6.

There are multiple spikes 20-33, and the spikes 20-33 are arranged on the inner wall of the outer wall 20-6;

[0053] The mixing mechanism 20-4 includes a second rotating shaft 20-41, a second rotating shaft motor 20-42, a mixing fan 20-43, a mixing chamber 20-44, and a bottom plate 20-45;

[0054] The second rotating shaft motor 20-42 is arranged at the center of the screen frame 20-36, the second rotating shaft 20-41 is arranged at the bottom of the screen frame 20-36 and is connected to the second rotating shaft motor 20-42, the mixing bin 20-44 is arranged at the bottom of the screen frame 20-36, the mixing fan 20-43 is arranged on the surface of the second rotating shaft 20-41, the bottom plate 20-45 is arranged at the bottom of the mixing bin 20-44, and a first through hole 20-46 is arranged on the surface of the bottom plate 20-45, and the first through hole 20-46 is communicated with the processing mechanism 20-5.

[0055] The working principle of the above technical solution is as follows: during the waste recycling process, when the waste fragments enter the screening mechanism 20-3, the first shaft motor 20-2 drives the first rotating shaft 20-31 to rotate, and then drives the rotating fan 20-34 to rotate with the first rotating shaft 20-31. At the same time, the push rod 20-32 makes up and down reciprocating motion under the action of the cylinder and then pushes the sleeve 20-38 to reciprocate up and down. When the push rod 20-32 is pushed upward, the sleeve 20-38 moves up, and the spring 20-37 is compressed. At this time, the rotating fan 20-34 flips upward under the action of the hole groove, thereby driving the waste fragments to flip upward, and then being further crushed and ground by the spikes 20-33. When the push rod 20-32 is retracted downward, the sleeve 20-38 moves downward, and the spring 20-37 stretches. At this time, the rotating fan 20-34 flips downward under the action of the hole slot, so that the waste fragments contact the spikes 20-33 again; when the waste fragments are broken into small enough pieces and in the form of waste powder under the action of the rotating fan 20-34, they fall to the bottom of the sieve plate 20-35. The sieve plate 20-35 rotates synchronously with the rotating fan 20-34 under the action of the first rotating shaft 20-31, so that the sieve column 20-39 drives the waste powder to rotate. The second rotating shaft motor 20-42 drives the second rotating shaft 20-41 to rotate, thereby driving the mixing fan 20-43 to rotate along with the second rotating shaft 20-41. After the waste powder is fully mixed by the mixing fan 20-43, it enters the first through hole 20-46 set on the surface of the bottom plate 20-45 and is then transmitted to the processing mechanism 20-5 for further processing.

[0056] Beneficial effects of the above technical solution: Through the design of the above structure, this embodiment provides the specific structure of the screening mechanism 20-3 and the mixing mechanism 20-4. The rotation and up and down flipping movement of the rotating fan 20-34 drives the waste fragments to be further crushed and ground, making the waste more finely divided and convenient for processing. The screening plate 20-35 and the sieve column 20-39 accelerate the filtering efficiency of the waste. The sieve frame 20-36 filters the waste, which indirectly improves the quality after reprocessing.
