Description
Technical field
The utility model relates to SLA printer technology fields, and in particular to a kind of SLA scraping device.
Background technique
It is a kind of technique for using stereo carving (Stereo Lithography) principle, letter that photosensitive resin, which selectively solidifies,
Claim SLA, is a kind of rapid shaping technique occurred earliest.Liquid photosensitive resin is filled in resin storage tank, it is in UV laser beam
Irradiation under can rapid curing, when forming process starts, liftable workbench is in the height of the next section thickness of liquid level,
Laser beam after focusing according to the requirement of cross section profile, is scanned under control of the computer along liquid level, makes scanned area
The resin solidification in domain, to obtain the resin flake of the cross section profile.Then, workbench declines the height of one layer of thin slice, with solid
The resin flake of change is just covered by one layer of new liquid resin, to carry out second layer laser scanning solidification, new cured one
Layer jail is bonded in preceding layer, is so repeated endlessly, until entire formed product finishes.Last lifting platform rises from liquid resin table
Workpiece is taken out in face, cleaned, remove support, secondary curing and any surface finish processing etc..
Due to the new resin liquid that during being layering to form product, is covered on cured resin due to viscosity and
Under the action of cured resin surface tension etc., only leaning on resin to flow to naturally, liquid level is smooth to be takeed a long time, and is passed through
Scraper plate auxiliary, may be implemented the quick levelling of liquid level.In addition, printer has extra high requirement to the temperature of material when working,
Nowadays the method for the most common control temperature is heater by being fixed on resin storage tank by all resins in entire trough
It is heated to operating temperature.The shortcomings that this mode is that heating time is long, and the temperature control of working region resin can relatively lag behind.Tree
Resin long-time heating and heating are uneven in rouge slot, and having a significant impact to resin property or even local resin sometimes occur becomes
The phenomenon that matter.
Utility model content
The purpose of this utility model is to provide a kind of SLA scraping devices, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the utility model provides the following technical solutions: a kind of SLA scraping device, including bracket, storage
The middle part of hopper, feeding engine, conveying pipeline, thermometer, electric heating sheets, scraper, the scraper is equipped with discharge hole, the discharging
Hole is connected to stock chest, and the front and rear sides of the discharge hole are designed with doctor edge, and the stock chest is installed on the cross of bracket
Beam center, the feeding engine are installed on the top of material storing box, conveying pipeline, the stock chest are connected on the feeding engine
Lower part two sides surface on be separately installed with electric heating sheets, pacify at the centre of electric heating sheets in the stock chest
Equipped with thermometer, the scraper is installed on the bottom of stock chest.
Further, the structure of the doctor edge is tooth form.
Compared with prior art, the utility model has the beneficial effects that the device is in the process of work, feeding engine is continuous
Resin liquid is transported in stock chest by ground, and resin liquid is after entering stock chest, by the heating of stock chest two sides electric heating sheets, from
It is flowed out in the discharge hole of scraper, the thermometer in stock chest can survey the temperature of the resin liquid of outflow stock chest in real time
Fixed, print system controls the heating speed of electric heating sheets by thermometric temperature, the tree after stock chest is heated
Rouge liquid sprawls one layer in printing plane with the movement of scraper, and making to print the resin temperature in plane can satisfy printing requirement,
And during scraper is struck off, the doctor edge of tooth form can be struck off the bubble on resin liquid surface in print cup, be prevented
Bubble has an impact printing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the left cross-sectional view of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As depicted in figs. 1 and 2, a kind of SLA scraping device described in the utility model, including bracket 1, stock chest 2, feeding
3, conveying pipeline 4, thermometer 5, electric heating sheets 6, scraper 7 are pumped, stock chest 2 is installed on 11 center of crossbeam of bracket 1, and feeding engine 3 is pacified
Top loaded on stock chest 2 is connected with conveying pipeline 4 on feeding engine 3, is separately installed on the surface of the lower part two sides of stock chest 2
Electric heating sheets 6, the interior centre positioned at electric heating sheets 6 of stock chest 2 are equipped with thermometer 5, and scraper 7 is installed on stock chest 2
The middle part of bottom, scraper 7 is equipped with discharge hole 71, and discharge hole 71 is connected to stock chest 2, and the front and rear sides of discharge hole 71, which are designed with, scrapes
The structure of blade 72, doctor edge 72 is tooth form, and in the process of work, resin liquid is constantly transported to the device by feeding engine 3
In stock chest 2, resin liquid is after entering stock chest 2, by the heating of 2 two sides electric heating sheets 6 of stock chest, from the discharging of scraper 7
It is flowed out in hole 71, the thermometer 5 in stock chest 2 can carry out the real time measure, printing to the temperature of the resin liquid of outflow stock chest 2
System passes through the temperature that thermometer 5 measures, and controls the heating speed of electric heating sheets 6, the resin after stock chest 2 is heated
Liquid sprawls one layer in printing plane with the movement of scraper 7, and making to print the resin temperature in plane can satisfy printing requirement,
And during scraper 7 is struck off, the doctor edge 7 of tooth form can be struck off the bubble on resin liquid surface in print cup, be prevented
Only bubble has an impact printing.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
