Description
Technical field
The present invention relates to a kind of dusty material shapes process units, the powder particularly to 3D printing paves mechanism.
Background technology
In prior art, sand mold 3D printing equipment, the work(that its sanding system only sand material conveys and every layer of sand material is paved
Can, there is following both sides problem：One side is that the flatness on the layer of sand surface after tiling does not detect and feeds back, the opposing party
Face is that the layer of sand after tiling does not have consolidation.Just there is very big problem in the sand mold intensity so producing, the foundry goods produced will
There is corresponding casting flaw, such as：Surface quality of continuous castings is poor, has the problems such as scab, vein, low precision.
Content of the invention
It is an object of the invention to provide a kind of sanding of 3D printing and mold compacting device are so as to not only can conveying, paving sand material,
Each layer of sand material consolidation also can be made simultaneously, reach the optimum state before every layer of printing, be finally reached the sand mold producing in precision
And the index such as the degree of packing reaches casting standard.
The object of the present invention is achieved like this：A kind of sanding of 3D printing and mold compacting device, including sand feed bin, sand feed bin
Frame bottom be arranged in line slideway drive mechanism, in sand feed bin, level is provided with auger conveyor, below auger conveyor
Level is provided with sieve sand net, and sieve sand side off the net is provided with sand export, and the described metastomium that shakes out is provided with stragith edge, and stragith edge cuts with scissors through connecting rod
It is connected on sand feed bin, stragith edge is provided with bearing contiguous block, bearing contiguous block is provided with eccentric shaft, the axle of eccentric shaft through bearing
End is provided with the eccentric spindle motor driving eccentric shaft turns.
During present invention work, under the driving of line slideway drive mechanism, sand feed bin can move forward and backward.Sand material adds sand material
Storehouse, augur simultaneously, sand material is evenly distributed in inside whole sand feed bin.Sand material within sand feed bin is through screened sand
After net filtration, uniformly spill from sand export, fall on work platformses, when line slideway drive mechanism moves forward and backward, drive is strike-off
Plate synchronously strikes off the sand material spilling.During sanding, under eccentric shaft Motor drive, eccentric shaft is made under the support of bearing
High speed rotary motion, drives stragith edge dither, so, sand material, under the dither of stragith edge, is vibrated consolidation simultaneously.
Compared with prior art, the present invention not only can guarantee that sand material is uniformly shakeout, and sand material can be made closely knit, before reaching every layer of printing
Optimum state, be finally reached the sand mold producing and reach casting standard in the index such as precision and the degree of packing.Solve foundry goods table
The ropy problem in face, this device is applied to 3D printing casting industry.
For ensureing that sand material is more prone to by scraping blade and closely knit, described stragith edge is 0 ~ 5 ° with horizontal plane angle.
For ease of adding sand, described sand feed bin upper one end is provided with infundibulate and adds sand mouth.For the material position adding sand can be controlled, described
It is provided with for controlling the level sensor stopping adding sand in sand feed bin, after in sand feed bin, sand material is filled it up with, level sensor sends letter
Number control sanding device stop plus sand.
Brief description
Fig. 1 is present configuration schematic diagram.
Fig. 2 is partial structurtes left view of the present invention.
Wherein, 1 sand feed bin, 2 level sensors, 3 auger conveyors, 4 conveying motors, 5 sand exports, 6 sieve sand nets, 7 strike-off
Plate, 8 eccentric shafts, 9 bearings, 10 eccentric spindle motors, 11 line slideway drive mechanisms, 12 servomotors, 13 work platformses, 14 add sand
Mouthful, 15 connecting rods, 16 contiguous blocks.
Specific embodiment
As illustrated in fig. 1 and 2, it is a kind of sanding of 3D printing and mold compacting device, including sand feed bin 1, sand feed bin 1 upper one end
It is provided with infundibulate and adds sand mouth 14, the frame bottom of sand feed bin 1 is arranged in line slideway drive mechanism 11, line slideway driving machine
Structure 11 can drive sand feed bin 1 to move forward and backward by servomotor 12；In sand feed bin 1, level is provided with auger conveyor 3, helical feed
Device 3 end is provided with conveying motor 4, when conveying motor 4 rotates, can convey sand material to the other end from sand feed bin 1 one end, so that will
Sand material uniformly paves in sand feed bin 1；Auger conveyor 3 lower horizontal is provided with sieve sand net 6, is provided with sand export below sieve sand net 6
5, the position of sand export 5 should be corresponding with work platformses 13, and sand export 5 rear portion is provided with stragith edge 7, and stragith edge 7 is through connecting rod 15
It is hinged on sand feed bin, stragith edge 7 is provided with bearing contiguous block 16, and bearing contiguous block 16 is provided with eccentric shaft 8 through bearing 9,
The axle head of eccentric shaft 8 is provided with the eccentric spindle motor 10 driving eccentric shaft 8 to rotate；Described stragith edge 7 and horizontal plane angle be 0 ~
5°.
It is provided with sand feed bin 1 for controlling the level sensor 2 stopping adding sand.
During work, under the driving of line slideway drive mechanism 11, sand feed bin 1 can move forward and backward, sand material from plus sand mouth add
Enter sand feed bin 1, auger conveyor 3 rotates simultaneously, sand material is evenly distributed in inside whole sand feed bin 1.In sand feed bin 1, sand material adds
Man Hou, level sensor 2 sending signal controls sanding device to stop plus sand.Sand material within sand feed bin 1 filters through screened sand net 6
Afterwards, uniformly spill from sand export 5, fall on work platformses 13, when line slideway drive mechanism 11 moves forward and backward, drive stragith edge
7 synchronizations strike off the sand material spilling.During sanding, under eccentric spindle motor 10 drives, eccentric shaft 8 is in the support of bearing 9
Under make high speed rotary motion, drive stragith edge 7 dither, so, sand material, under the dither of stragith edge 7, is scraped simultaneously
Sand plate 7 vibration ramming, it is to avoid the problem of scab, vein, low precision occurs.The sand mold producing is in the index such as precision and the degree of packing
Can reach casting standard.
The invention is not limited in above-described embodiment, on the basis of technical scheme disclosed by the invention, the skill of this area
