Problems solved by technology

[0005] 1. The feeding device is prone to wear and tear during the working process, which will lead to problems such as abnormal wire feeding and unstable wire feeding;
[0006] 2. Some of the feed inlet and outlet of the existing feeding device are too small, and some are too large. If the wire is too small, if there is some deviation or deformation, it is easy to cause stuck phenomenon, and if it is too large, it will affect the feeding accuracy. influences

Abstract

The invention discloses a silk material extrusion device for a 3D printer nozzle. The silk material extrusion device comprises a driving device and an elastic base. The driving device comprises a motor and a gear. An output shaft of the motor is sleeved with the gear. The elastic base comprises a base body, a handle, a guide wheel and a spring located between the base body and the handle, and the two ends of the spring abut against the base body and the handle correspondingly. The output shaft of the motor penetrates through the base body, and the base body is fixed to the motor. The base body is provided with a first rotary shaft sleeved with the handle. The handle is provided with a second rotary shaft sleeved with the guide wheel. The silk material extrusion device has high feed precision and reliability and is simple in structure and low in cost.

Description

technical field [0001] The invention relates to the field of an FDM fused deposition 3D printer, in particular to a filament extruding device of a nozzle. Background technique [0002] The idea of ​​3D printer originated at the end of the 19th century and was developed and promoted in the 1980s. Its scientific name is "rapid prototyping". The principle of the FDM fused deposition 3D printer is that the thermoplastic filamentary material is sent from the filament extrusion device to the hot melt nozzle, and heated and melted into a semi-liquid state in the nozzle, and then extruded, selectively coated in the work On the table, after rapid cooling, a layer of sheet contour with a certain thickness is formed. After the cross-section of a layer is formed, the workbench is lowered to a certain height, and then the next layer is deposited, and so on, and finally a three-dimensional product part is formed. [0003] The feeding speed and pressure of the wire extrusion device of the...
