The 3D printer allows full-automatic operation and does not need manual intervention, so that the production cost is lowered, the production efficiency is improved, and unnecessary loss caused by material ageing is reduced.

Description

3D printer
Technical field
The present invention relates to a kind of printer, particularly relate to a kind of 3D printer.
Background technology
3D printer can be realized by a variety of technology, and present industrialization aspect is most popular is belonging to laser powder sintering technology SLS. SLS method adopts infrared laser to make the energy, and the Modeling Material of use mostly is dusty material. Add man-hour, first powder is preheating to the temperature being slightly less than its fusing point, then under the effect of Gua Fen mechanism, powder is paved; Laser beam sinters selectively according to layering cross section information under the control of the computer, one layer complete after carry out next layer of sintering again, remove unnecessary powder after all having sintered, then can be obtained by a part sintered. The sintering of all layers can be automatically performed, but existing technology is after part has sintered, it is necessary to staff is got involved to open machine and take out shaping bucket and cooled down, if processed not in time, also result in the powder body inside molding bucket aging, reduce the cyclic utilization rate of powder, improve use cost; If also need to manpower intervention in festivals or holidays, necessary needs are manually on duty, increase the cost of labor used. Thermal insulation barn owing to shaping bucket needs good heat insulating, so the hatch door of thermal insulation barn is thick big, is unfavorable for carrying out automatically opening up and directly opens hatch door cooling, and high temperature can conduct along header, can burn out roof door and other sheet metal components.
Summary of the invention
The technical problem to be solved is to provide a kind of 3D printer, and it realizes full-automatic operation, it is not necessary to manpower intervention, reduces production cost, improves production efficiency, and reduces the unnecessary loss caused because of material aging.
The present invention solves above-mentioned technical problem by following technical proposals: a kind of 3D printer, it is characterized in that, it includes ventilation shaft, forced-ventilated fan, intake valve, air bleeding valve, shaping bucket, one end of ventilation shaft is connected with air bleeding valve, the other end of ventilation shaft is connected with forced-ventilated fan, air bleeding valve is positioned at the side shaping bucket, and intake valve is positioned at the bottom shaping bucket.
Preferably, described shaping bucket is provided with air vent, and air vent connects with air bleeding valve.
Preferably, described shaping bucket is provided with air inlet, and air inlet connects with intake valve.
Preferably, the side of described forced-ventilated fan is provided with top row QI KOU, and top row QI KOU is connected with ventilation shaft.
Preferably, described forced-ventilated fan, top row QI KOU are all located on a flat board.
Preferably, described shaping bucket is arranged in a frame.
Preferably, the bottom of described frame is provided with roller and cushion block.
The actively progressive effect of the present invention is in that: the present invention realizes full-automatic operation, it is not necessary to manpower intervention, reduces production cost, improves production efficiency, and reduces the unnecessary loss caused because of material aging.
Accompanying drawing explanation
Fig. 1 is the side perspective view of 3D printer of the present invention.
Fig. 2 is the opposite side perspective view of 3D printer of the present invention.
Detailed description of the invention
Present pre-ferred embodiments is provided, to describe technical scheme in detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2,3D printer of the present invention includes ventilation shaft 1, forced-ventilated fan 2, intake valve 3, air bleeding valve 4, shapes bucket 5, one end of ventilation shaft 1 is connected with air bleeding valve 4, the other end of ventilation shaft 1 is connected with forced-ventilated fan 2, air bleeding valve 4 is positioned at the side shaping bucket 5, and intake valve 3 is positioned at the bottom shaping bucket 5.
Shaping bucket 5 and be provided with air vent 6, air vent 6 connects with air bleeding valve 4, so conveniently controls aerofluxus.
Shaping bucket 5 and be provided with air inlet 7, air inlet 7 connects with intake valve 3, so conveniently controls air inlet.
The side of forced-ventilated fan 2 is provided with top row QI KOU 8, and top row QI KOU 8 is connected with ventilation shaft 1, and top row QI KOU is convenient discharges gas.
Forced-ventilated fan 2, top row QI KOU 8 are all located on a flat board 10, so increase stability.
Shape bucket 5 to be arranged in a frame 9, so increase stability.
The bottom of frame 9 is provided with roller 10 and cushion block 11, is so moved easily and fixes.
The present invention is at the ventilation shaft of free convection plus forced-ventilated fan combination, and by the two ore control of intake valve and air bleeding valve, system is when machine normal operation, and intake valve and air bleeding valve close, and allows the heat of system is unlikely to be scattered and disappeared. When machine is in cooling stage time, system can detect the cooling situation shaping bucket, suitably open intake valve and air bleeding valve, allow shaping bucket carry out natural convection current cooling, and opening forced-ventilated fan at the appropriate time, to carry out forced-ventilated air-cooled, accelerates the process of cooling, accelerate the process of cooling as far as possible under shaping the indeformable situation of workpiece inside bucket as far as possible, whole process need not the intervention of staff, automatically carry out, decrease the cost of manpower intervention and loss that maloperation causes.
Ventilation shaft and air inlet and exhaust valve are all high temperature resistant special-purpose members, otherwise can not bear the discharge of high-temperature gas, damage valve body and pipeline.
The switching of temperature control is the deadline according to temperature and operation, when the temperature of shaping bucket is also in high temperature, first open intake valve and air bleeding valve, it is not switched on forced-ventilated fan, shaping bucket is allowed to utilize convective principles slow cooling, like this just it is unlikely to allow the temperature shaping bucket reduce too fast, causes the workpiece deformation of the inside. After the temperature shaping bucket drops to certain temperature, system automatically opens up forced-ventilated fan, accelerates cooling, strengthens cooling effect.
In sum, the present invention realizes full-automatic operation, it is not necessary to manpower intervention, reduces production cost, improves production efficiency, and reduces the unnecessary loss caused because of material aging.
Particular embodiments described above; the solving the technical problem that of the present invention, technical scheme and beneficial effect have been further described; it is it should be understood that; the foregoing is only specific embodiments of the invention; it is not limited to the present invention; all within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
