Abstract
The invention discloses an FDM machine gear-rack transmission double-printing-head linkage lifting mechanism. The mechanism comprises a frame. Linear guide rails and sliding blocks assembled on the linear guide rails are fixedly arranged on the left and right sides of the frame correspondingly. Wire feeding motors are fixed to the sliding blocks. The sliding block on each side is connected with a printing head support. Printing heads are arranged on the printing head supports. The adjacent ends of the printing head supports on the two sides are provided with racks. A gear is arranged between the racks and engaged with the racks. The gear and the racks form a gear-rack transmission mechanism, so that the two printing heads ascend and descend integrally in a linked mode, and the gears are driven by the motors. Automatic switching of the two printing heads can be achieved, composite preparation of two materials is achieved, and the effect that scratching or interference between the idle printing heads and printed pieces is avoided in the forming process is ensured, so that the formed piece yield is effectively increased.
Description
Technical field
The invention belongs to increases material manufacturing technology field, is related to a kind of pair of printhead linkage lifting, especially a kind of FDM
Double printhead linkage liftings of machine rack pinion.
Background technology
3D printing is being commonly called as increases material manufacturing technology (AM, Additive Manufacturing).3D printing, it is entitled " to beat
Print ", actually " manufactures ".In fact, in substantial amounts of english literature, 3D printing (3D Printing) is often referred to as 3D
Fabrication (3D manufactures), this more accurately describes the essence of 3D printing.Scott when FDM technology is the eighties in 20th century
Crump inventions.After the patent for obtaining the technology, he established Stratasys companies in 1989.The technology of FDM is former
Reason：Heat fusing, shower nozzle bottom is added to carry minute nozzle (diameter one by shower nozzle the thermoplastic of thread (diameter about 2mm)
As be 0.2～0.6mm).Material is squeezed with certain pressure and gushed out, while shower nozzle is moved in the horizontal direction, the material of extrusion with
Previous aspect clinkering is together.After the completion of one aspect deposition, table vertical declines the thickness of a layer, is further continued for melting
Deposition, until completing whole solid modelling.
The current FDM printing devices with double printing heads on the market, between generally existing printing head and drip molding
Scratch and interference problem.In forming process, when a printing head performs one section of print routine in both given layers, because of two
The height of shower nozzle is consistent substantially, once exist having the raised or burr of already formed material on operating path, may result in
Interfere between idle nozzle and drip molding, whole drip molding is departed from substrate by the serious shower nozzle that will cause, and causes to print
Failure.
It is proposed that " single-motor double shower nozzle 3D printer shower head mechanism " (patent No. CN201310422519.4) send out
Bright patent.It is mainly a kind of single-motor double shower nozzle 3D printer for driving two shower nozzles to carry out double-colored printing by a motor
Shower head mechanism.But this scheme does not solve the problems, such as that two shower nozzles may interfere.
Thus it is guaranteed that when double nozzle printing machines are printed, idle nozzle is not interfered with printing-forming part, while and ensureing
Change back and forth between two shower nozzles it is smooth with it is convenient, design a kind of pair of printhead linkage lifting there is highly important meaning
Justice.
The content of the invention
It is an object of the invention to overcome the shortcoming of above-mentioned prior art, there is provided a kind of FDM machines rack pinion it is double
Printhead linkage lifting.It can realize the automatic switchover of double printheads, realize the compound preparation of bi-material layers, and ensure into
The shower nozzle that leaves unused during shape does not scratch or interferes with printout, effectively improves drip molding qualification rate.
The purpose of the present invention is achieved through the following technical solutions：
Double printhead linkage liftings of this FDM machines rack pinion, including framework, in the framework left and right sides point
Line slideway and the slide block being assemblied on line slideway are not fixedly installed, slide block is fixed with wire feeding motor；Each side slide
Be respectively connected with printing head support, be provided with printing head on printing head support, both sides printing head support it is adjacent one
End is provided with tooth bar, and a gear is engaged between two tooth bars, and the wheel and rack constitutes rack and pinion drive mechanism and makes
Two printing head Coupled motions liftings are obtained, the gear is by Motor drive.
Further, above-mentioned motor is fixedly installed on the centre position that frame mid portion two prints head cartridge.
Further, said gear is spur gear, and tooth bar is spur rack.
Further, said gear is angular gear, and tooth bar is diagonal-cut rack.
Further, said gear is curved tooth gear, and tooth bar is curved tooth tooth bar.
Further, above-mentioned line slideway is that square ball line slideway, twin shaft core roller line slideway or single shaft core are straight
Line guide rail.
The invention has the advantages that：
1st, the present invention can realize the composite printing of bi-material.
2nd, the present invention can work, automatic switchover of the spare bits under print routine control, conversion station response is fast, can have
Effect solves interference problem.
3rd, the present invention can pass through the control of motor corner, realize the regulation of avoidance height, carry out efficiency optimization design.

Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings：
Referring to Fig. 1,2,3, the present invention includes stand 1 and the line slideway 8 installed in the left and right sides of stand 1, and straight line
Slide block 2 on guide rail 8 is fixed with wire feeding motor 7, and in the middle part of stand 1 motor 4 is fixed with, and is driven by motor 4
The dynamic rack and pinion drive mechanism being made up of gear 5 and tooth bar 6 is so that two Coupled motion of printing head 3 liftings.
The united needle that the present invention is adopted is for whole printing head.If doing linkage lifting, nozzle and silk material just for nozzle
Between can produce relative motion.Nozzle causes certain stretching or compression to silk material, can produce having some setbacks for silk material supply, very
It is interrupted to printing silk material is caused.Two printing heads is highly not consistent during original state, it is ensured that certain altitude is poor, needs to turn
When changing printing head, the relative altitude position of two printing heads is changed by motor.In whole process, turning between shower nozzle
Change program need be consistent with motor drive signal, with ensure switching motion it is smooth with it is accurate.
