Problems solved by technology

But its disadvantage is that it is far away from the nozzle, and the wire is not a rigid material, so it cannot provide enough extrusion force to the nozzle, which is easy to cause insufficient extrusion, unevenness, etc., which is reflected in the surface of the printed product is uneven, and some parts are layered. Obvious, deformed, cracked

Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] In conjunction with the accompanying drawings, a dual-motor wire conveying device for FDM printers includes a short-distance extrusion structure 1, a remote conveyance structure 2, a nozzle 3, a wire material disk 4, a wire 5 and a wire conduit 6, and the short-distance extrusion The other end of the short-distance extrusion structure 1 is connected to the wire guide 6, and the wire 5 passes through the wire material disk 4, the remote delivery structure 2 and the wire guide 6, and is subjected to close The pulling force provided by the extrusion structure 1 passes through the nozzle 3.

[0018] The remote conveying structure 2 drives the wire material disc 4 to rotate by pulling the wire 5 .

[0019] The proximal extrusion structure 1 includes a first motor, and the remote delivery structure 2 includes a second motor.

[0020] The transmission line ...

Abstract

The invention relates to the technical field of conveying devices, in particular to a dual-motor wire conveying device for an FDM printer. The dual-motor wire conveying device comprises a short-rangeextrusion structure, a long-range conveying structure, a spray head, a wire tray, a wire and a wire guide pipe. The short-range extrusion structure and the spray head are connected, the other end of the short-range extrusion structure is connected with the wire guide pipe, and the wire penetrates through the wire tray, the long-range conveying structure and the wire guide pipe, is subjected to thepulling force provided by the short-range extrusion structure and passes through the spray head. Accordingly, printing is more stable, printing quality is improved, the weight of the short-range extrusion structure is reduced, the influences of inertia on high-speed printing conditions are reduced, stability of precise control over movement of the spray head is improved, and printing time is shortened.

Description

technical field [0001] The invention relates to the technical field of conveying devices, in particular to a dual-motor wire conveying device for FDM printers. Background technique [0002] FDM: Fused Deposition Modeling, which uses filamentous hot-melt materials as raw materials, is melted by heating, and the liquefied raw materials are extruded through a nozzle of a fine nozzle, and deposited on the panel or the previous layer of solidified material First, it starts to solidify after the temperature is lower than the melting point, and accumulates layer by layer to form a 3D printing method of the final product. [0003] Wire: refers to filamentous hot-melt materials, which are pre-processed into circular wires of specific diameters. Commonly used materials include ABS, PLA, artificial rubber, cast wax and polyester thermoplastics. [0004] Nozzle: a device with a fine nozzle at the bottom, which squeezes out the liquid material in the molten state through the pressure fo...
