Description
【Technical field】
The utility model is related to the doctor blade device on a kind of 3D printer.
【Background technology】
Existing laser powder sinters three-dimensional printer, and working cycles are that workbench declines one layer, then by scraper
One layer is spread in working face, is begun to warm up, after reaching operating temperature, laser starts scanning, and then workbench declines one layer, opens
Begin next working cycles.Because powder is added inside scraper relative to operating temperature than relatively low powder adding barrel, and scraper sheet
The temperature come is not high, so powder generally just carries out powdering when not being fully warmed-up, can like this increase powdering
Afterwards the heat time of working face, reduce the efficiency of work；The temperature difference of powdering is big, can be easily caused molded workpiece and produce
Raw buckling deformation.Scraper is excessive with the temperature difference of powder, powder can be allowed seriously to adhere on scraper, allows the scraper can not normal work
Make.During whole powdering, system will not pre-heating powder, it is necessary to powdering is completed, then the surface of powdering is carried out pre-
Heat, this when, the surface of firm powdering was very big, it is necessary to long time is carried out with the temperature difference for needing to reach when sintering
Preheating, is so greatly lowered the efficiency of whole sintering process.
【Utility model content】
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of simple structure, and doctor blade device can either
Powder in heating scraper, so as to reduce powder and the doctor blade device temperature difference, can carry infrared heating device preheating powdering powder again
The band at end heats the doctor blade device of scraper.
In order to solve the above problems, the utility model uses following technical scheme：
A kind of doctor blade device with heating scraper, including blade platform, described blade platform be provided with slide guide frame, can be
The doctor blade device slided on described slide guide frame, the servomotor for driving described doctor blade device to slide, it is characterised in that：It is described
Doctor blade device be provided with the infrared heating device that can be heated to it.
A kind of doctor blade device with heating scraper as described above, it is characterised in that：Described doctor blade device is provided with to be scraped
Knife, described infrared heating device is located on described scraper side wall.
A kind of doctor blade device with heating scraper as described above, it is characterised in that：Described scraper is provided with bakie, institute
The infrared heating device stated is provided with two and is respectively provided in the two opposite side walls of described scraper.
A kind of doctor blade device with heating scraper as described above, it is characterised in that：Described slide guide frame is provided with slide guide
Crossbeam, described doctor blade device is provided with doctor blade holder, and described scraper is located at described doctor blade holder one end, and described doctor blade holder can
Slidably it is enclosed within described slide guide crossbeam.
A kind of doctor blade device with heating scraper as described above, it is characterised in that：The motor shaft of described servomotor
Driving wheel is provided with, described blade platform is provided with driven pulley, and conveyer belt is cased with described driving wheel and driven pulley, described
Conveyer belt side be fixed on described doctor blade holder.
A kind of doctor blade device with heating scraper as described above, it is characterised in that：Described infrared heating device includes
The temperature control equipment of the infrared heating fluorescent tube heating-up temperature described in infrared heating fluorescent tube and control.
The beneficial effects of the utility model have：Doctor blade device is provided with the infrared heating device that can be heated to its own and right
The infrared heating device that the outer powder of scraper is preheated, so when sintering is started, can preheat to scraper, reach certain
Just carry out scraping powder, the temperature difference that can so reduce between scraper and powder after temperature, it is ensured that scraper can be stablized scrapes powder, and
Powder that can be with powdering during powdering is preheated, and reduces the time of heating process after powdering, greatly improves processing
Efficiency.
