Description

A kind of three-dimensional printer of multiple print head

Technical field

The present invention relates to a kind of 3 D-printing equipment, refer in particular to a kind of three-dimensional printer that can greatly improve a kind of multiple print head of printing effect here.

Background technology

At present, in research and development of products design, popular employing stereolithography machine printed product mould, can overcome the high expense of traditional fabrication product model molding.Stereolithography machine on market, can extrude the ABS of diameter 1.75 to 3.0 mm or the plastics silk thread of PLA, approximately 160 ℃ ~ 230 ℃ of extruder head temperature.Plastic wire is printed to the three-dimensional model of object, the map file of three-dimensional model is divided into the section of equal thickness by software, again every one deck two dimensional cross-section cooked up to scanning pattern and filled up by the plastics of extruding, sequentially the plastics of extruding are attached on the table plate of stereolithography machine, for protecting, adheres on table plate the plastic wire Cui that can extrude, table plate need be heated to 60 ~ 120 ℃, otherwise the fritting plastic wire of extruding runs into cold table plate, chilling and cannot being attached on table plate.General on table plate, post the material that fritting plastics that one deck is convenient to extrude adhere to, optimal selection is Kapton Tape, it can resistance to 250 ℃ of high temperature, the plastics that this high temperature heat-resistant adhesive tape is extruded for covering the adhesive force of heater plate surface increase printed material, by the bottom, upwards fill every layer of section, until top section finally prints a 3 D stereo finished product

Because above-mentioned procedure of processing multilayer is filled up plastics, therefore complete a three-dimensional finished product long period consuming time, now three-dimensional printer, once can only print the sample of a product, if need to print the sample of a plurality of products, printing is will efficiency lower, process longly, can affect designer's operating efficiency.

The specific embodiment

Below in conjunction with Figure of description, the invention will be further described:

As Figure 1-4, the three-dimensional printer of a kind of multiple print head provided by the invention, it comprises printer support body 1, mobile platform face 2, is arranged on the table plate 3 on mobile platform face 2, in printer support body 1 inner side, by bezel locations, two mobile slide-bars 4 are vertically set, a plurality of printing extruder heads 5 are installed on the vertical plane of vertical mobile slide-bar 4, between a plurality of printing extruder heads 5, be provided with a plurality of connecting rods 6, in printer support body 1 outside bezel locations, plastic wire drum 7 be installed.As shown in Figure 2, described a plurality of printing extruder heads 5 enter motor 50 by cloth and drive, wherein each stepper motor 50 is by the coiling of A group and the coiling of B group, and each A group coiling circuit of printing the stepper motor of extruder head is connected in series, and each B group coiling circuit of printing the stepper motor of extruder head is connected in series.Described a plurality of printing extruder head 5 numbers are provided with 2-4, preferential 2.As shown in Figure 3, in figure, there are two cloth to enter the coiling of A group and the B group coiling series connection respectively of motor 50.

Described printing extruder head 5 comprises clamp arm 51, discharging stepper motor 50, clamp arm pivot 52, spring support 53, extrude tooth 54 and heating tube 56, on clamp arm 51, be provided with through wires hole, and clamp arm 51 is printed on extruder head 5 by the hinged installation of clamp arm pivot 52, spring by spring support 53 and spring support 53 makes clamp arm 51 lower ends and extrudes tooth 54 compressions, and make plastics silk thread 9 wear clamp arm 51 lower ends and extrude between tooth 54, discharging stepper motor 50 drives extrudes tooth 54 rotations, plastics silk thread 9 is sent into heating tube 56, in heating tube 56 lower ends, be provided with a plurality of extrusion cavities.

Operation principle of the present invention is as follows: when the plastics silk thread 9 of ABS or PLA, via clamp arm 51, plastics silk thread 9 being close to by discharging stepper motor 50 drives and extrudes tooth 54, extrude after tooth 54 is clamp-oned heating tube 56 heating by plastics silk thread 9 and become fritting shape plastics, be attached on table plate 3 or on the plastics of front one deck.Clamping force is by being fixed on spring energized in clamp arm 51 front ends on the spring support 53 of clamp arm 51, via the clamp arm pivot 52 on clamp arm 51, make to be closely attached on plastics silk thread 9 after clamp arm 51 rotations, make plastics silk thread 9 and extrude the tight pressing of tooth 54, when extruding tooth 54 and rotarily driven by stepper motor 50, because of the angle of rotation, moving of generation and push plastics silk thread 9 and enter heating tube 56, by heating tube 56 front ends, in the aperture of diameter 0.3 ~ 0.5 ㎜, extrude again.

As a kind of alternative, described extruder head is replaceable is Solid State Laser head.Described Solid State Laser head is selected wavelength 340nm to 455nm, power 50mw to 1000mw.Plastics silk thread 9 adopts photosensitive resin to substitute.

In a word, the present invention is adopted as and current singles are printed to extruder head 5 changes the extruder heads 5 of printing more into, the stepper motor series connection 50 of printing extruder head 5 will be controlled, when printing extruder head 5 in straight line or the same moving motion of camber line, its straight line or camber line displacement are equivalent to the length of moulding that should extrude, therefore being responsible for each stepper motor amount of spin of extruding head needs identically, thereby extrudes the fritting plastics of equal length and makes product even.The three-dimensional printer of this structure, once prints, and can make much product samples, has greatly improved three-dimensional printer operating efficiency.

The above is only to preferred embodiment of the present invention; not scope of the present invention is limited; therefore design under the prerequisite of spirit not departing from the present invention; the equivalence that the common engineers and technicians in this area do structure of the present invention, feature and principle changes or decorates, and all should fall in the protection domain of the present patent application patent.
