Description
Technical field
The utility model provide it is a kind of elevating mechanism is struck off based on SLA principle 3D printers, belong to rapid shaping and set
Standby technical field.
Background technology
SLA techniques are also referred to as light chisel or stereolithography, are that the photopolymerization principle based on liquid photosensitive resin works.It is this
Photopolymerization reaction can occur rapidly under the ultraviolet light of certain wavelength and intensity for liquid material, and molecular weight increased dramatically, material
Material also just changes from liquid to solid.
Liquid photocurable resin is filled with resin storage tank, laser beam can scan, light under deflecting mirror effect on liquid surface
The place that point is got to, liquid just solidify.When shaping starts, objective table is in the depth of the next determination of liquid level, and laser is on liquid level
By the instruction point by point scanning of computer, i.e., point-by-point solidification.After the completion of one layer of scanning, not illuminated place is still liquid tree
Fat.Then elevating mechanism band dynamic object stage declines a layer height, is covered with one layer of resin again in molded aspect, will by scraper plate
The larger resin liquid level of viscosity strikes off, and then carries out next layer of scanning again.
Defect present in prior art is, when scraper plate strikes off resin liquid level, because resin viscosity is very big, is easy to
Stick together with blade surface, first, causing scraper plate larger resistance when running to be present, strike off less efficient；Second, adhesion can cause
Resin liquid level flatness after striking off is low；Third, the resin for sticking in blade surface also needs to be cleared up in time.
Utility model content
To solve the above problems, the utility model provide it is a kind of elevating mechanism is struck off based on SLA principle 3D printers,
Concrete scheme is：
A kind of elevating mechanism that strikes off based on SLA principle 3D printers, including scraping located at 3D printer resin cartridge top
Flattening mechanism, and the elevating mechanism being connected with 3D printer objective table, the sandwich include scraper plate, and the scraper plate is located at tree
On the horizontal guide rail on fat box top；The bottom of the scraper plate is provided with blowing mouth, and length direction of the blowing mouth along scraper plate is distributed,
The air channel connected with blowing mouth is provided with inside scraper plate, air channel is connected with blast pipe；The elevating mechanism includes turn-screw and erected
Straight guide, the upright guide rail are located at the side wall of resin cartridge, and on upright guide rail, the turn-screw is used to drive objective table
Objective table moves along upright guide rail.
Further, the blowing mouth is opened in scraper plate bottom.
Further, the scraper plate bottom is provided with groove, and groove is set along scraper plate length direction, and the blowing mouth is positioned at recessed
Inside groove.
Further, the scraper plate bottom is provided with a plurality of equally distributed parallel groove, and every bottom portion of groove, which is equipped with, to be blown
Air port.
Further, the width of the blowing mouth is 0.5~2mm.
Further, upper strata air channel and lower floor air channel are provided with inside the scraper plate, lower floor air channel connects with blowing mouth, upper strata
Air channel connects with blast pipe, is connected between upper strata air channel and lower floor air channel by pressure distribution hole.
Further, the blast pipe is provided with pressure-regulating valve.
Beneficial point of the present utility model is：Scraper plate in this programme is provided with blowing mouth, by from blowing mouth jet-stream wind,
Scraper plate bottom formed airflow layer, when striking off resin liquid level, blade surface no longer directly contacts with resin, so as to avoid because
The defects of low efficiency, liquid level planarization difference are struck off caused by resin adhesion, scraper plate is without being cleared up；In improved technology,
By setting groove in scraper plate bottom, the distributed areas of air-flow can be controlled；, can by setting double-deck air channel and pressure distribution hole
To avoid stream pressure uneven.
