Description
Technical field
The present invention relates to conveying device technical field, in particular to a kind of bi-motor wire rod conveyings for FDM printers
Device.
Background technology
FDM：Fusion sediment Fused Deposition Modeling are using Filamentous heat-fusible materials as raw material,
By heating and meltings, the raw material after liquefaction are squeezed by the nozzle of a subtle nozzle and are gushed out, be deposited on make panel or
On the cured material of person's preceding layer, temperature starts to cure after being less than fusing point, and successively accumulation forms a kind of 3D of final finished product
Printing type.
Wire rod：Refer to Filamentous heat-fusible materials, be pre-machined into the round wire rod of specified caliber, common material have ABS,
PLA, artificial rubber, casting wax and polyester thermoplastic's plastics etc..
Nozzle：Bottom carries subtle nozzle, and pressure is formed by by the extruding of follow-up wire rod, will be under molten condition
Liquid material squeezes the device to gush out.3D printer is exactly by being realized to cephalomotor accurately control of nozzle/extrusion in fact
Printout.
FDM printers carry out wire rod conveying using single motor and provide extrusion force at present.According to motor position difference, have with
Lower two ways：One is using motor and the integrated short range conveying of nozzle, another is then using motor and nozzle point
From long-range conveying.
The advantages of short range conveys be motor from nozzle closer to, extruded material evenly, but due to motor offline material disk
Farther out, pulls wire disk of material is also wanted while providing extrusion force to nozzle, it is insufficient is susceptible to conveying.It is embodied in printout
On be then that skin lamination is apparent, cracking, product intensity is inadequate；It, must in print procedure since motor and nozzle are combined together
It must move together, increase the weight of entire nozzle structure, increase and the difficulty accurately controlled is moved to nozzle.Especially in high speed
In the case of printing, when changing nozzle movement velocity, direction, due to effect of inertia, it be easy to cause nozzle position offset so that
There is deformation, cracking in printout, or even scraps.
The advantages of long-range conveying, is that motor offline material disk is close, it is easier to pulls wire disk of material；Nozzle is light-weight, more holds
Easily realize accurate motion control.But the disadvantage is that farther out from nozzle, wire rod is not rigid material, can not provide enough extrusions
Power to nozzle, be easy to cause extrusion it is insufficient, it is uneven and situations such as, it is surface irregularity, part position to be embodied in printout then
The case where setting apparent layering, appearance deformation, cracking.
Invention content
The technical problem to be solved by the present invention is to overcome the defects of above-mentioned technology, provide a kind of for the double of FDM printers
Motor wire feeder device.
In order to solve the above technical problems, technical solution provided by the invention is a kind of bi-motor line for FDM printers
Material conveying device：Structure, long-range structure for conveying, nozzle, wire rod charging tray, wire rod and duct are squeezed out including short range, it is described close
Journey squeezes out to be connected between structure and nozzle, and the other end that the short range squeezes out structure is connected with duct, and the wire rod is worn
Wire rod charging tray, long-range structure for conveying and duct is crossed the pulling force of structure offer is being provided by short range and is passing through spray later
Head.
As an improvement, the long-range structure for conveying is by pulling wire rod to drive the rotation of wire rod charging tray.
As an improvement, it includes first motor that the short range, which squeezes out structure, the long-range structure for conveying includes the second motor.
As an improvement, the first motor is identical with the transmission linear velocity of the second motor, the direction for transmitting wire rod is consistent.
A kind of bi-motor wire feeder device for FDM printers of the invention has the following advantages that：It combines traditional
Short range conveys and long-range conveying advantage so that printing is more stable, improves print quality.Because of the second motor, then
One motor no longer needs big torque to go pulls wire disk of material because of it, so that it may using low torque, light-weight motor, to reduce
Short range squeezes out the weight of structure, reduces the influence of inertia in the case of flying print, improves and is accurately controlled to nozzle movement
Stability.The quality that can guarantee printout in the case of flying print, to greatly shorten the time-write interval.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of bi-motor wire feeder device for FDM printers of the invention.
As shown in the figure：1, short range squeezes out structure, and 2, long-range structure for conveying, 3, nozzle, 4, wire rod charging tray, 5, wire rod, 6, line
Material conduit.
Specific implementation mode
Present invention will be described in further detail below with reference to the accompanying drawings.
In conjunction with attached drawing, a kind of bi-motor wire feeder device for FDM printers, including short range squeeze out structure 1, long-range
Structure for conveying 2, nozzle 3, wire rod charging tray 4, wire rod 5 and duct 6, the short range squeezes out to be connected between structure 1 and nozzle 3,
The short range squeezes out the other end of structure 1 and duct 6 connects, and the wire rod 5 passes through wire rod charging tray 4, long-range conveying knot
