Abstract
Various embodiments provide a filament replacement mechanism for a 3D printer and a 3D printing system. In those embodiments, the filament replacement mechanism includes: a support; a filament guide unit disposed on the support and including a plurality of secondary filament guide tubes and a filament guide opening connecting with the plurality of secondary filament guide tubes, where the filament guide opening is configured to be jointed with a main filament guide tube of the 3D printer, and a plurality of filament replacement units disposed on the support.
Claims20
A 3D printing system, comprising:
- a 3D printer;
- and
- a filament replacement mechanism comprising:
- a support;
- a filament guide unit disposed on the support and comprising a plurality of secondary filament guide tubes and a filament guide opening connecting with the plurality of secondary filament guide tubes, wherein the filament guide opening is configured to be jointed with a main filament guide tube of the 3D printer;
- and
- a plurality of filament replacement units disposed on the support, each of the plurality of filament replacement units comprises:
- a supporting shaft assembly rotatably connected to the support and configured to be in contact with a rim of the corresponding filament spool so as to support the corresponding filament spool, wherein the supporting shaft assembly comprises a first supporting shaft set and a second supporting shaft set rotatably connected to the support separately and spaced apart from each other in a circumferential direction of the corresponding filament spool, wherein a first axis of rotation of the first supporting shaft set, a second axis of rotation of the second supporting shaft set and an axis of rotation of the corresponding filament spool are parallel to one another;
- and
- a loading and unloading mechanism configured to drive a filament wound around the corresponding filament spool to enable the filament to be guided into the main filament guide tube via one corresponding secondary filament guide tube of the plurality of secondary filament guide tubes so as to perform a loading operation, and configured to drive the corresponding filament spool to rotate such that the filament withdrawn from the main filament guide tube via the filament guide unit is rewound around the corresponding filament spool so as to perform an unloading operation;
- a circuit board disposed between every two adjacent filament spools of the plurality of filament spools, wherein a recognition sensor is provided on the circuit board and configured to recognize identification information of at least one of the filament spools;
- at least one separator is disposed on a surface of the support facing a plurality of filament spools, the at least one separator is arranged at intervals in the direction of the array of the plurality of filament spool, thereby dividing the support into a plurality of segments, each segment accommodates at least a portion of a corresponding filament spool;
- and
- the plurality of secondary filament guide tubes are located on the side of the support away from the separator, and are positioned below the plurality of filament spools, One end of each corresponding secondary filament guide tube, away from the filament guide opening, is arranged adjacent to the first support shaft set;
- the filament guide opening is arranged in a middle region on the side of the support close to the second support shaft set.

A 3D printing system, comprising:
- a 3D printer;
- and
- a multi-channel member, the multi-channel member has an outlet and a plurality of inlets connecting with the outlet, and the outlet is connected to the 3D printer;
- and
- a plurality of filament replacement units, each of the plurality of filament replacement units comprises:
- a supporting shaft assembly, which is in contact with a rim of the corresponding filament spool so as to support the corresponding filament spool;
- and a loading and unloading mechanism, which is provided with a channel for the filament to penetrate through;
