Description
Technical field
The utility model is related to powder conveying device field, especially a kind of spiral powder conveying device.
Background technology
It is carried out currently, 3D printing course powder supply mode relies primarily on spiral powder conveying device, existing spiral
Formula powder conveying device is worked according to Mechanics of Machinery principle, is made of screw rod, hopper, powder bucket, mixer and vibrator.
Screw rod is driven by motor to be rotated, and drives powder to be moved along powder bucket spiral inner wall slot, and be transported in mixer.In mixer
Current-carrying gas powder is fluidly transferred out.It is accurate to measure in order to make powder be full of in helicla flute, in powder
Bottom struggle against equipped with vibrator.Screw rod, hopper, powder bucket, mixer be in have in the gas-tight silo of current-carrying gas.Its powder sending quantity and spiral shell
The rotary speed of bar is directly proportional, and the rotating speed of adjusting control screw rod rotary electric machine can accurately control powder sending quantity.This powder feeder
High sensitivity, reliable and stable, powder feeding is uniform, but is not suitable for the different mixed-powder of proportion and the different powder of granularity, and
Easily stifled powder.
Invention content
The technical problem to be solved by the utility model is to provide a kind of spiral powder conveying devices, are ensureing powder feeding effect
Under the premise of rate, solves the problems, such as the frangible problem of particle when device blocks up powder and conveys composite particles.
In order to solve the above technical problems, technical solution used by the utility model is：A kind of spiral powder conveying dress
It sets, including holder, holder is equipped with locating ring, is equipped with outer housing in locating ring, the outer housing is internally provided with spiral powder feeding
The upper end of mechanism, spiral powder feeding mechanism is connect by screw thread with connecting rod lower end, the upper end of connecting rod and the output of servo motor
Axis connection, the outer housing bottom are equipped with three-way connection.
In preferred scheme, the spiral powder feeding mechanism and outer housing are all made of cone-shaped structure, and the spiral is sent
Powder mechanism outer wall is equipped with external screw thread, and externally threaded diameter of section gradually decreasees from top to bottom.
In preferred scheme, powder feeding funnel is additionally provided on the holder, powder feeding funnel is arranged in servo motor and shell
Between body, and the discharge end of powder feeding funnel extends in outer housing.
In preferred scheme, the spiral powder feeding mechanism lower end is equipped with nipple, three-way connection and spiral powder feeding machine
It is threadedly coupled between structure, two interfaces of residue of the three-way connection are separately connected air inlet pipe and an air outlet pipe.
A kind of spiral powder conveying device provided by the utility model has by using above structure with following
Beneficial effect：
（1）Spiral powder feeding mechanism is connected by outer housing and three-way connection, and the powder in three-way connection within a fitting can
It enough realizes that quick wind is sent, is conducive to powder smooth delivery of power, be not in stifled powder situation；
（2）Whole device carries out powder feeding using vertical direction, is connect with servomotor, is conducive to the defeated of friable powder
It send, spiral powder feeding mechanism will not occur and cause powder fragmentation with outer housing inner-wall extrusion friction；
（3）Spiral powder feeding mechanism uses conical structure, since cone is smaller in the remoter speed in the same cross-sectional distance center of circle,
Speed is bigger more down on axis, therefore can effectively improve the efficiency of powder feeding.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples：
Fig. 1 is the overall structure diagram of the utility model.
Fig. 2 is the perspective structure schematic diagram of outer housing in the utility model Fig. 1.
Fig. 3 is the spiral powder feeding mechanism structural schematic diagram of the utility model.
In figure：Spiral powder feeding mechanism 1, outer housing 2, connecting rod 3, servo motor 4, holder 5, powder feeding funnel 6, locating ring 7,
Three-way connection 8.
Specific implementation mode
As in Fig. 1-3, a kind of spiral powder conveying device, including holder 5, holder 5 are equipped with locating ring 7, locating ring 7
In be equipped with outer housing 2, the outer housing 2 is internally provided with spiral powder feeding mechanism 1, and the upper end of spiral powder feeding mechanism 1 passes through screw thread
It is connect with 3 lower end of connecting rod, the upper end of connecting rod 3 and the output axis connection of servo motor 4,2 bottom of outer housing is equipped with
Three-way connection.
In preferred scheme, the spiral powder feeding mechanism 1 and outer housing 2 are all made of cone-shaped structure, the spiral
1 outer wall of powder feeding mechanism is equipped with external screw thread, and externally threaded diameter of section gradually decreasees from top to bottom.Using the spiral shell of conical structure
Powder feeding mechanism 1 and outer housing 2 are revolved, since cone is smaller in the remoter speed in the same cross-sectional distance center of circle, speed more down on axis
It is bigger, therefore the speed of powder is gradually increased, can accelerate powder output speed, promotes powder delivery efficiency.
In preferred scheme, powder feeding funnel 6 is additionally provided on the holder 5, powder feeding funnel 6 is arranged in 4 He of servo motor
Between outer housing 2, and the discharge end of powder feeding funnel 6 extends in outer housing 2.
In preferred scheme, 1 lower end of spiral powder feeding mechanism is equipped with nipple, three-way connection 8 and spiral powder feeding
It is threadedly coupled between mechanism 1, two interfaces of residue of the three-way connection 8 are separately connected air inlet pipe and an air outlet pipe.By adopting
It can be kept away by passing through 8 air of three-way connection quickly to take powder out of with above structure when powder drops down onto in three-way connection 8
The blocking for having exempted from pipeline keeps powder feeding operation more smooth.
Using the above structure, spiral powder feeding mechanism is connected by outer housing and three-way connection, the powder in three-way connection
It can realize that quick wind is sent, and is conducive to powder smooth delivery of power within a fitting, be not in stifled powder situation；Whole device is using vertical
Direction carries out powder feeding, is connect with servomotor, is conducive to the conveying of friable powder, spiral powder feeding mechanism and shell will not occur
Body inner-wall extrusion friction causes powder fragmentation；Spiral powder feeding mechanism uses conical structure, since cone is in same cross-sectional distance
The remoter speed in the center of circle is smaller, and speed is bigger more down on axis, therefore can effectively improve the efficiency of powder feeding.
