Description
Technical field
The present invention relates to a kind of feed devices.More particularly, to a kind of fine powder spiral feeder.
Background technology
Screw conveyor is a kind of using motor drive spiral revolution, promotes material to realize the machinery of conveying purpose.Spiral shell
Rotation conveyer is made of screw shaft, barrel, bearing arrangement and a driving device equipped with helical blade etc..When helical axis turns
When dynamic, due to material gravity and its with groove body wall caused by frictional force, make material can only be under the push of blade along defeated
The slot bottom of machine is sent to move forward, it is the same that the screw rod of situation similar not revolvable nut along rotation does translational motion.It is tied
Structure has the characteristics that：(1) simple in structure, cost is relatively low；(2) reliable operation is safeguarded simple and convenient；(3) compact dimensions, section
Size is small；(4) sealing transport can be achieved.But it is there is also certain shortcoming, such as conveying mesh number smaller powder when, for spiral shell
It is very high that the spindle nose of rotation conveyer sits up straight sealing, the design requirement of bearing seal, and dust is easily accessible rotary gap and into bearing
In, cause power consumption big, bearing wear is accelerated, and particularly when powder has certain viscosity, is easy to cause bonding, influences spiral shell
The normal rotation of spin axis.
The content of the invention
In view of the above, it is necessary to provide that a kind of leakproofness is good, simple in structure, stability is good, lower-cost thin
Powder spiral feeder.
