Embodiment 1

[0035] like Figure 1-Figure 7 As shown, this embodiment provides an extrusion device for a 3D printer, the extrusion device includes an extrusion body 1 and a feeding wrench 14, and the extrusion body 1 is rotatably provided with an extrusion fixed wheel 11 and an extrusion arm 12. On the extrusion arm 12, there is an extrusion moving wheel 121 that can selectively approach or move away from the extrusion fixed wheel 11. Consumables can be extruded through the approaching extrusion fixed wheel 11 and the extrusion moving wheel 121. The extrusion arm One end of 12 is in elastic contact with the extrusion body 1 through the elastic member 13, so as to drive the extrusion driving wheel 121 close to the extrusion fixed wheel 11; set and abut against one end of the extrusion arm 12 , and turn the feeding wrench 14 to drive the extrusion moving wheel 121 away from the extrusion fixed wheel 11 .

[0036] By setting the extrusion fixed wheel 11 and the extrusion moving wheel 121 on ...

Embodiment 2

[0050] This embodiment discloses a 3D printer, which includes a printing drive device and an extrusion device as described in Embodiment 1 arranged on the print drive device. The structure is simple, the operation is simple when replenishing consumables, and the efficiency is high; the extrusion force can be adjusted Large; can be quickly disassembled, easy to adjust and replace.

Abstract

The invention relates to the technical field of 3D printers, and discloses an extrusion device and a 3D printer. The extrusion device comprises an extrusion body and a feeding wrench; an extrusion fixed wheel and an extrusion arm are rotationally arranged on the extrusion body, an extrusion movable wheel which can be selectively close to or away from the extrusion fixed wheel is rotationally arranged on the extrusion arm, consumables can be extruded out through the extrusion fixed wheel and the extrusion movable wheel which are close to each other, and one end of the extrusion arm elastically abuts against the extrusion body through an elastic piece so as to drive the extrusion movable wheel to be close to the extrusion fixed wheel; the feeding wrench is rotationally arranged on the extrusion body, one end of the feeding wrench is arranged in a reducing mode and abuts against one end of the extrusion arm, and the feeding wrench is rotated to drive the extrusion movable wheel to be away from the extrusion fixed wheel. When the feeding wrench is rotated, the extrusion movable wheel can be close to or away from the extrusion fixed wheel so as to feed or extrude materials, and the extrusion device is simple in structure, convenient to operate and high in feeding operation efficiency.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to an extrusion device and a 3D printer. Background technique [0002] 3D printing (3DP), that is, rapid prototyping technology, is a cumulative manufacturing technology, also known as additive manufacturing. It is based on a digital model file, using special wax, powdered metal or plastic and other bondable materials. Print layers of adhesive material to create three-dimensional objects. Fused deposition rapid prototyping (FDM), also known as hot melt deposition technology, is one of the main 3D printing technologies. This technology is to heat and melt the hot-melt filament material and extrude it from the printing nozzle, and deposit it on the printing platform or the previous layer of solidified material. When the temperature is lower than the solidification temperature of the filament, it begins to solidify and form, and finally prints entity. [0003] In the prior art, ...
