Abstract

The invention relates to the technical field of 3D printers, and particularly discloses a double-nozzle switching device and a 3D printer. The double-nozzle switching device comprises a back plate, a supporting seat, a first spray head assembly, a second spray head assembly, a first reversing block and a second reversing block. The supporting seat is rotationally arranged on the back plate; the first spray head assembly and the second spray head assembly are both arranged on the supporting seat, the supporting seat can swing between a first position and a second position relative to the back plate, and when the supporting seat is located in the first position, the first spray head assembly is located below the second spray head assembly; when the supporting seat is located in the second position, the first spray head assembly is located above the second spray head assembly, the first reversing block can abut against the supporting seat to push the supporting seat to rotate to the second position, the second reversing block can abut against the supporting seat to push the supporting seat to rotate to the first position, and thus position switching of the two spray head assemblies is achieved; structures such as a motor gear and the like are not required to be arranged on the back plate, so that the weight of components on the back plate can be reduced, and the printing efficiency and precision can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a dual-nozzle switching device and a 3D printer. Background technique [0002] Existing 3D printers are usually equipped with two nozzles in order to be able to print two-color or different materials, and the two nozzles need to be switched frequently during the working process. [0003] The existing dual-nozzle switching method, such as the rotary dual-nozzle switching device for 3D printing proposed in the previous patent with the application number CN201510052482. When the rack is meshed, the second bracket swings passively to the right in a pendulum-like manner on the first bracket with the center of rotation as the center of the circle, so that an angle difference is generated between the two nozzle devices, thereby realizing a longitudinal height difference and switching between dual nozzle devices avoidance function. However, the dual nozzle switching device needs to...
