Description

Technical Field

[0001] This utility model belongs to the field of 3D laser printer technology, specifically relating to an anti-splash mechanism for 3D laser printers. Background Technology

[0002] Laser 3D printing is a type of rapid prototyping technology. 3D printing uses a digital model as a reference, inputting digital programs into the 3D printer, which then shapes the object by sintering powdered metal or other materials layer by layer. During the sintering process, sparks can be generated due to the oxygen environment in the air, affecting other parts of the metal powder.

[0003] A utility model patent with publication number CN202322282898.3 discloses an anti-splash mechanism for a 3D laser printer, comprising a main body and a protective mechanism disposed on the outer wall of the main body. The protective mechanism includes a sliding component and a flipping component. When 3D printing an object using a 3D laser printer, to improve the protection of the print head during printing and prevent splashing, a knob can be rotated to drive a threaded rod to slide along the inner wall of a fixed groove. Simultaneously, the threaded rod slides along the inner wall of a limiting groove. The rotation of a swing rod causes the protective plate to flip along the outer wall of the printing table, thus protecting both sides of the printing table.

[0004] The above solution cannot be used in a synchronous manner with the protective plate and the side plate. In addition, there is a gap between the protective plate and the side plate, which can easily cause metal powder to splash. The protection range is limited. Furthermore, it cannot automatically clean the metal powder adhering to the protective plate during storage. Therefore, we propose an anti-splashing mechanism for 3D laser printers. Utility Model Content

The splash-proof structure 3 includes a square frame 35, on which a front protective plate 33 and a side protective plate 34 are symmetrically arranged. The front protective plate 33 is movably arranged in the front storage opening 2, and the side protective plate 34 is movably arranged in the side storage opening 5. A lower mounting plate 31 is arranged between the base frames 4. A hydraulic cylinder 32 is arranged on the lower mounting plate 31. The piston rod of the hydraulic cylinder 32 is connected to the square frame 35. Specifically, the hydraulic cylinder 32 is also connected to the control box 6, and the extension and retraction of the hydraulic cylinder 32 can be controlled through the control box 6. Please see Figure 4 as well as Figure 5 A gap protection section is also provided between the front protective plate 33 and the side protective plate 34. The gap protection section includes a front auxiliary baffle 303 and a side auxiliary baffle 306.
