Abstract

The invention discloses a 3D printing wire feeding, clamping and guiding device, and relates to the technical field of quick molding of 3D printing. The 3D printing wire feeding, clamping and guiding device comprises a guide wheel I and a guide wheel II; the guide wheel I and the guide wheel II are arranged side by side; a lap of V-shaped tooth grooves I, inwards recessed, is formed in the peripheral surface of the guide wheel I; a lap of V-shaped tooth grooves II, inwards recessed, is formed in the peripheral surface of the guide wheel II; the V-shaped tooth grooves I in the guide wheel I and the V-shaped tooth grooves II in the guide wheel II are opposite in position; when the guide wheel I and the guide wheel II are arranged side by side, the V-shaped tooth grooves I and the V-shaped tooth grooves II surround guide grooves for clamping and guiding wires; waste grooves I communicated with the V-shaped tooth grooves I are inwards recessed in the inner sides of the V-shaped tooth grooves I; and waste grooves II communicated with the V-shaped tooth grooves II are inwards recessed in the inner sides of the V-shaped tooth grooves II. The 3D printing wire feeding, clamping and guiding device can improve the wire surface clamping engagement force and friction force to prevent the wire slip or deviation in the feeding process.

Description

technical field

[0001] The invention relates to the technical field of 3D printing rapid prototyping manufacturing, in particular to a 3D printing filament feeding and clamping guide device. Background technique

[0002] 3D printing rapid prototyping manufacturing technology is becoming more and more mature, and its application is becoming more and more extensive. FDM (Fused Deposition Modeling, Fused Deposition Manufacturing) printing technology is widely used in the 3D printing rapid prototyping of plastic products because of its good manufacturability, convenient operation, and environmentally friendly use. The filament for FDM3D printing has a large market need.

[0003] However, at present, the surface of the clamping guide wheel of the filament used for FDM3D printing is generally a smooth surface, or a small amount of knurled surface. During the printing process, when the feeding mechanism transports the filament, due to the smooth surface of the guide wheel and the ...
