A 3D printer extrusion structure, comprising: a housing; a motor provided on the housing; an active extrusion gear provided in the housing and connected to the motor; an adjusting support rotatably connected inside the housing; a driven extrusion gear provided at one end of the adjusting support and rotatably connected to the adjusting support; and an elastic member, the elastic member being connected to an other end of the adjusting support to enable the end of the adjusting support provided with the driven extrusion gear to approach the active extrusion gear, so that the driven extrusion gear works in conjunction with the active extrusion gear to extrude material, wherein the end of the adjusting support provided with the driven extrusion gear extends to the outside of the housing.

3D printer extrusion structure

The present disclosure relates to a switching device and a 3D printing apparatus. The switching device includes a rack, an extrusion assembly, a pushing assembly and a driving assembly. The extrusion assembly is connected to the rack and includes a driving roller and a first pressing wheel and a second pressing wheel located on a circumferential outer side of the driving roller. Transport channels allowing consumables to pass are formed between the driving roller and the first pressing wheel and between the driving roller and the second pressing wheel for passing a consumable. The driving assembly and the pushing assembly are connected to the rack; the pushing assembly includes a pushing portion, and the pushing portion is capable of pushing a target consumable to move relative to driving roller to a preset position corresponding to the target consumable under a drive of the driving assembly, so as to restrict the target consumable from moving.
