Problems solved by technology

When the existing wire feeder is replacing the wire harness, the threading channel of the wire harness will deflect at a small angle, usually about 5 degrees, which makes it difficult for the wire harness to align with the wire harness channel, which is quite troublesome

Abstract

The invention discloses a filament feeding mechanism of a 3D printer. The filament feeding mechanism comprises a base, a handle assembly, a returning spring and a driving motor; the handle assembly isrotatably connected with the base and comprises an "L"-shaped handle main body, a pressing wheel and a guider, wherein the head of the handle main body is provided with a hollow guide cavity, the center of the guider is provided with a through guide channel, and the guider is rotatably arranged in the guide cavity; the returning spring is arranged on the handle main body; and the driving motor isdetachably arranged on the base, an output shaft of the driving motor is provided with a driving gear, and the driving gear is matched with the pressing wheel. Due to the fact that the guider is always aligned with a filament bundle channel, filament bundle threading can be easily completed and is convenient and fast.

Description

technical field [0001] The invention relates to a 3D printer accessory, more precisely, a wire feeding mechanism of a 3D printer. Background technique [0002] There is usually a wire feeder on the 3D printer, and the function of the wire feeder is to draw the wire bundle from the wire reel and send it to the high-temperature extrusion head at a certain speed. When the existing wire feeder is replacing the wire harness, the threading passage of the wire harness will be deflected at a small angle, usually about 5 degrees, which makes it difficult for the wire harness to align with the wire harness passage, which is quite troublesome. Contents of the invention [0003] The present invention mainly solves the technical problems existing in the prior art, thereby providing a wire feeding mechanism of a 3D printer. [0004] Above-mentioned technical problem of the present invention is mainly solved by following technical scheme: [0005] A wire feeding mechanism of a 3D print...
