Velocity gradient optimized type planet agitator

Abstract

The invention discloses a velocity gradient optimized type planet agitator. The velocity gradient optimized type planet agitator comprises a machine shell, a driving device and agitator shafts, wherein the quantity of the agitator shafts is one or more than one; the driving device comprises a box body which is driven to rotate through the driving mechanism, as well as a sun wheel and driving gear groups arranged in the box body, and the quantity of the driving gear groups is as the same as that of the agitator shafts; each driving gear group comprises a first planet gear and a second planet gear which is coaxially sleeved on the corresponding agitator shaft; the first planet gear, the second planet gear and the sun wheel are arranged on the same horizontal plane and the center point of the second planet gear, the center point of the first planet gear and the center point of the sun wheel are non-collinear; and the first planet gear is meshed with the sun wheel, and the second planet gear is meshed with the first planet gear. The velocity gradient optimized type planet agitator provided by the invention has the advantages that the structure is simple, the design is reasonable, the use and operation are simple, the using effect is good, and the velocity gradient optimized type planet agitator solves problems that the existing upright shaft planet agitator has the problem that the distribution of an agitator blade kinematic velocity filed is not uniform, and the velocity gradient is large and the like.

Description

technical field [0001] The invention relates to a planetary mixer, in particular to a speed gradient optimized planetary mixer. Background technique [0002] In the mixing machinery of the mixture, the movement track of the mixing blades of the vertical shaft planetary mixing machines currently on the market is mostly a long epitrochoid. The gradient is large, and the distribution of stirring linear velocity and angular velocity is unreasonable, and even a static point (that is, the point where the stirring velocity is zero) will appear due to the superposition of rotation and revolution velocity. This is due to the unreasonable design of the mixer transmission mechanism, which causes the stirring speed of the stirring device to be very uneven and the speed gradient is large, that is, the stirring speed of some blades in the stirring device is too high and the stirring speed of the other part of the blades is too small. During the mixing process, the speed of the state chan...
