Smoothly discharge.After wind turbine 187 is stopped, window leaf is sagging under the effect of gravity, prevent extraneous sleet, bulky grain dust into
Enter.By the setting of draft mechanism, matched with heating air draft mechanism, the pernicious gas being further discharged from exhaust outlet 112
It is discharged to outside wall.During being distilled and being sprayed, the equipment heated in air draft mechanism and draft mechanism is in power-off
State prevents solvent distillation or spray coating liquor from causing equipment short-circuit.After distillation or after spraying, then carry out air inducing and row
Wind.
As shown in figure 12, the sandboard 186 is provided with multiple S-shaped air ducts 187,187, the S-shaped air duct from top to bottom
Height and position in the port of inside, higher than the port positioned at outside.Such setting can make the particulate matter being blown into from outside
Into after S-shaped air duct 187, due to the limitation of 187 shape of S-shaped air duct, sandboard can be slipped to along the surface in S-shaped air duct 187
186 outside, without entering 186 inside of sandboard.
3D printing piece surface processing unit provided by the utility model, by surface smooth treatment and the organic knot of spray treatment
It is combined, while being also equipped with the function of support.By controller to each component in 3D printing piece surface processing unit
Working condition is controlled.When being distilled and being sprayed, unnecessary electrical equipment is set to be in power-off shape by controller
State prevents the short circuit for causing electrical equipment.
The 3D printing piece surface processing work process that the utility model also provides is as follows：
The 3D printing part that printing is completed is put on the holder 170 in working bin 111, is cooled down.Printing is completed
It is carried out within five minutes afterwards cooling effective.The type of cooling is by inciting somebody to action the ultrasonic wave high frequency oscillation atomizer in water tank 114
Water atomization in water tank 114, atomized water are diffused into 111 space of entire working bin, can be cooled down to 3D printing part, together
When, the support section on 3D printing part is water-soluble material, under the action of atomized water, can dissolve support section and go
It removes.The cooling time is 20 minutes.
Heater strip 182 is powered, and fan 181 is made to be in air intake mode, by heat blow to working bin 111, to 3D
Printing part is heated, and keeps the temperature in working bin 111 at 110 degrees Celsius, continuous heating 1 hour, to increase level chain
Connect intensity.
The distillation hole 117 distilled on case 115 is opened, and the heating device in distillation case 115 is made to work, by distilling second
Alcohol or acetone equal solvent, are processed by shot blasting 3D printing part, and the polishing treatment time is 20 minutes.
Control holder 170 is rotated around vertical axis, is sprayed on solidify liquid by the second spout 164 on gunjet rack 160
3D printing piece surface.Altogether carry out twice solidify liquid spray, each spray time be 2 minutes, twice solidify liquid spraying between
Every 15 minutes.
After solidify liquid spraying is completed 15 minutes, paint film will be sprayed to 3D piece surfaces by the first spout 163, carry out three altogether
Secondary paint film spraying, each paint film spray time are 2 minutes, are spaced after last paint film spraying and carry out within 15 minutes next time one again
Paint film sprays.
Through the above steps, realizing goes support, surface smooth treatment and surface spraying to handle 3D printing part, makes processing
3D printing piece surface smoothness afterwards promotes 50%, and toughness promotes 70%, can be by 3D printing object thickness reduces by 50%, can
Realize ultra-thin printing.
It is not only in the description and the implementation although the embodiments of the present invention have been disclosed as above
Listed utilization.It can be applied to various fields suitable for the present invention completely.For those skilled in the art,
Other modifications may be easily implemented.Therefore without departing from the general concept defined in the claims and the equivalent scope, this reality
It is not limited to specific details and legend shown and described herein with novel.
