Description
Technical field
This utility model relates to the parallel arm 3D of a kind of improvement and prints engraving machine feeding printhead.
Background technology
3D printing technique occurs in the mid-90 in 20th century, and the technology such as actually utilize photocuring and ply of paper folded is
New rapid molding device.It is essentially identical with normal printer operation principle, and printer " prints material built with liquid or powder etc.
Material ", after being connected with computer, control " printed material " to stack up from level to level, finally the blueprint on computer by computer
Become in kind.This printing technique is referred to as 3D three-dimensional printing technology.1986, Charles Hull developed First business 3D
Printer.1993, the Massachusetts Institute of Technology obtained 3D printing technology patent.Nineteen ninety-five, ZCorp company of the U.S. is from the Massachusetts Institute of Technology
Obtain exclusive authority and start to develop 3D printer.Again across attaining a new height after 2005, enter in polar mode
Row 3D prints.
The design process printed is: first pass through computer-aided design (CAD) or the modeling of computer animation modeling software, then
The threedimensional model " subregion " built up is become cross section successively, thus instructs printer successively to print.
The printhead of the 3D printer that existing vector is portable, is liquid or dusty material to be delivered to print point release
Put, allow liquid or dusty material solidify or stack shaping, continuously moved by printhead, successively pointwise release material
Material, finally forms designed three-dimensional workpiece in kind with regard to heap.Print as CN104552943 patent just belongs to such 3D
Machine.The printed material of existing this kind of printer is plastic wire mostly, it is simply that by extruder, plastic wire is delivered to printhead
It is fused into liquid, then by printing nozzle release heap knot.This kind of printer there is a problem that extruder is with printhead even
Together, due to temperature conduction and the collecting and distributing reason such as unreasonable of heater in print procedure so that plastic wire does not comes
And fusing is sent at nozzle, result results in blockage, or plastic wire not yet arrives at heater and is just melted, and causes nozzle
The material of release is not enough.Either fusing too early or the delay fusing of plastic wire all can cause workpiece shortcoming or multiple spot, work
Part deformation is lost shape, and finally makes printing failure.
Therefore, it is necessary to this type of 3D printer is improved.
Summary of the invention
The purpose of this utility model is just for the problems referred to above, and the parallel arm 3D printing engraving machine feeding proposing a kind of improvement is beaten
Print head, this feeding printhead can coordinate control software to be automatically adjusted according to the making requirement of different printed materials and workpiece
The time of heating and temperature, prevent the temperature local near nozzle from raising, it is ensured that plastic wire feeding speed and fusing time and spray
The close look at the swing of mouth, it is to avoid too early or delay fusing, with allowing printhead quasi-amount in time by liquid printed material release heap
Knot, it is ensured that print the quality of workpiece, solve the deficiencies in the prior art with this.
The parallel arm 3D of this improvement that the utility model proposes prints engraving machine feeding printhead, including extruder with beat
Print head, it is characterised in that extruder is fixed in the frame of 3D printer, printhead is arranged on the mounting of parallel arm crosslinking, squeezes
Going out and have wire-feeding pipe to be connected between machine with printhead, printhead is made up of nozzle, heat block, radiator and mounting, and nozzle is fixed on
On mounting, heat block is arranged on nozzle, equipped with radiator above heat block, has cooling fan by radiator；Extruder is by machine
Seat, motor, sting a gear and compress bearing composition, motor is installed on support and coaxially connected with stinging a gear
Transmission, compression bearing is close to sting a gear and is arranged on support.
Described compression bearing is regulated by housing pin with stinging the elasticity contacted between a gear.
Described extruder is arranged on the X post of frame, Y post or Z post and maintains static.
Described printhead cooling fan is arranged on mounting and moves.
Equipped with laser head on the mounting of printhead, in order to carry out carving operation.
This utility model, by the structure of original printhead with extruder unification, changes isolating construction into, and extruder no longer depends on
Printhead moves together, arranges radiator and cooling fan etc. at print-head nozzle, is dissipated in time by the waste heat of heat block, no
Only alleviate printhead weight so that it is action is the lightest sensitive, control software can be coordinated according to different printed materials and work
The requirement that makes of part is automatically adjusted time and the temperature of heating, prevents the temperature local near nozzle from raising, it is ensured that plastic wire send
Expect the close look at the swing of speed and fusing time and nozzle, it is to avoid too early or delay fusing, with allowing printhead quasi-amount in time
By liquid printed material release heap knot, it is ensured that print the quality of workpiece.

Machine is arranged on X post, naturally it is also possible to be arranged on other any one columns.Connect the wire feed between printhead and extruder
Pipe 2 is flexible pipe, and its effect is to allow plastic wire pass therethrough, and plays protection plastic wire, it is to avoid with the effect of other parts snarls.
The software controlling 3D printing engraving machine work is existing by Arduino mega2560 kernel control chip, adds
Ramps1.4 circuit board, drives 45 motor work through A4988 DMOS mini-step controlling device as stepper motor driver.
Print procedure is programmed controlling by standard G code.These are all the technology of existing maturation, wound the most of the present utility model
Make.
Equally, using Marlin Open Source Code, controlled by CNC nc standard G code, planning makes stepper drive stepping electricity
Machine motion realizes engraving and falls within prior art.Control software can be solidified into off line 8 and be arranged on frame lower, is allowed to and each step
Enter motor to connect, allow machine be automatically performed printing or engraving.
NM parts and label are described above.
Through the improvement of applicant's unit, done model machine stable working, completely eliminate original 3D and print engraving machine nozzle
Melt too early because of plastic wire or melt the clogging caused not in time, having accomplished the accurate enough input liquid of print-head nozzle
The purpose of plastics forming, done plastics part ten sectional specification, meet design requirement.Extruder is separated with printhead, pole simultaneously
Alleviate greatly printhead weight, reduce the live load of three motors, reduce power consumption, and make printhead lighter
The sensitiveest.
