The utility model discloses the sanding is even, the sanding is effectual, has improved production quality when having guaranteed production efficiency, is favorable to very much the sanding that humidity is inhomogeneous, the volume of piling up of sand reaches different bed thicknesss indefinitely.
Description
Technical field
This utility model belongs to three-dimensional (3D) printer field of sand mold, the most double roller sanding gears.
Background technology
The sand roller that pushes away of existing sand mold three-dimensional printer is usually one, pushes away sand roller and be close to sand during work
Surface carry out pushing away sand, when the humidity of sand is uneven, the sand of high humidity is easily pushed away too much,
The thickness causing sanding does not reaches expectation thickness；Instantly after sand, sanding surface sand heap everywhere
Accumulated amount variable interval, is easily caused the density unevenness even, layer of sand of the became uneven of layer of sand when pushing away sand and weighs,
The sanding edge situation without sand even occurs, has a strong impact on sanding effect and sand mold print quality；
When needing the sanding work carrying out different thickness, it is impossible to realize effectively regulation, thus cannot expire
Foot Production requirement.
Utility model content
This utility model is for the problems referred to above, it is provided that it is double that a kind of sanding is uniform, sanding is effective
Roller sanding gear.Technical problem to be solved in the utility model is real by following technical solution
Existing:
A kind of double roller sanding gear, pushes away sand roller including low level, and low level pushes away sand roller and is arranged on installing plate
On, low level is pushed away the two ends projecting shaft of sand roller and is flexibly connected with installing plate by bearing respectively, low level
The one end pushing away sand roller is connected by the first synchronization wheel and the first belt wheel Tong Bu with the second of motor,
Also including that a high position pushes away sand roller, a high position pushes away sand roller and is arranged on adjustable plate, adjustable plate and described installation
The connection of plate is adjustable fixing connection, and a high position pushes away the two ends projecting shaft of sand roller and passes through axle respectively
Holding and be flexibly connected with adjustable plate, the one end pushing away sand roller in a high position arranges the 3rd synchronization wheel, at low level
The other end pushing away sand roller arranges the 4th synchronization wheel, and the 3rd synchronizes wheel and the 4th synchronizes wheel by second
Belt connects.
Further, a high position pushes away sand roller and low level pushes away the length of sand roller roll surface more than maximum effectively paving
Sand width.
Further, a high position push away sand roller and low level to push away the difference in height between sand roller be 0.2mm
～10mm.
Especially, arranging strip through hole on adjustable plate, strip through hole passes through bolt and institute
State the fixing connection of installing plate.
This utility model sanding is uniform, sanding is effective, it is ensured that improve while production efficiency
The quality of production, is very beneficial for humidity accumulating amount uneven, sand indefinite and different thickness
Sanding.
With detailed description of the invention this utility model made further details of theory below in conjunction with the accompanying drawings
Bright.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is top view of the present utility model.
Detailed description of the invention
Fig. 1 is structural representation of the present utility model, and Fig. 2 is top view of the present utility model.
Shown in Fig. 1 and Fig. 2, a kind of double roller sanding gears, push away sand roller 3 including low level, low level pushes away
Sand roller 3 is arranged on installing plate 4, and low level pushes away the two ends projecting shaft of sand roller 3 and passes through bearing respectively
Being flexibly connected with installing plate 4, low level pushes away one end of sand roller 3 by the first synchronization wheel 3.2 and first
Belt 5 wheel Tong Bu with the second of motor 7 7.1 connection, also includes that a high position pushes away sand roller 1, and a high position pushes away
Sand roller 1 is arranged on adjustable plate 2, and adjustable plate 2 and the connection of installing plate 4 are adjustable solid
Fixed connection, the two ends projecting shaft that a high position pushes away sand roller 1 is movable even by bearing and adjustable plate 2 respectively
Connecing, the one end pushing away sand roller 1 in a high position arranges the 3rd synchronization wheel 1.1, pushes away the another of sand roller 3 at low level
One end arranges the 4th synchronization wheel 3.1, and the 3rd synchronizes wheel 1.1 and the 4th synchronizes wheel 3.1 by second
Belt 6 connects.
A high position pushes away sand roller 1 and low level pushes away the roll surface length of sand roller 3 more than maximum effectively sanding width；
A high position push away sand roller 1 and low level to push away the difference in height between sand roller 3 be 0.2mm～10mm, according to
The dry and wet degree of actual sand and the degree of packing of sanding, thickness require to regulate.
Arranging strip through hole 2.1 on adjustable plate 2, strip through hole 2.1 is by bolt and peace
Dress plate 4 is fixing to be connected, and is locked by bolt, needs to unclamp bolt during regulation height and just can carry out
Regulation, clamping screw the most again.
During work, sand under lower sand device, after lower sand terminates, sanding gear is according to the program set
Going back, a high position pushes away sand roller 1 and first touches sand and sand is bulldozed expansion, reduces the height of sand heap
Degree, then low level pushes away sand roller 3 and touches sand, and layer of sand is paved compacting, it is to avoid single push away sand
Rod directly acts on the high sand heap piled up thus damages the situation having printed layer of sand, thus obtains
The layer of sand of uniform ground.
In a word, this utility model sanding is uniform, sanding is effective, it is ensured that production efficiency same
Time improve the quality of production, be very beneficial for humidity accumulating amount uneven, sand indefinite and different
The sanding of thickness.
Although this utility model has been described in detail by embodiment, those of ordinary skill in the art
Should be appreciated that and still can modify the technical solution of the utility model and equivalent, it is equal
Should contain in the middle of right of the present utility model.
