Title A Three-dimensional Structure Design of centrifugal blender
Abstract
On the basis of the analysis of the function and performance of the centrifugal blender, also refer to a large amount of material, the general structure of the design scheme of the centrifugal blender is formulated.Through the small motor to drive the spindle rotation.The spindle is connected with the test tube support table. Test tube support platform rotates with the spindle. So the test tubes rotate around the spindle. This is the centrifugation movement. Drive the cam to rotate through the big electric motor. The cam is engaged with the tray of the small electric motor. The small motor tray is connected with the large motor casing through a sliding block guide rail. The cam rotates to drive the small motor to swing before and after. So the centrifugal part of the mechanism whole shake. It is the agitation motion. Finally using Solidworks for three-dimensional modeling, and draw out the2D engineering drawings.
Keywords centrifugation agitation Slide rail structural design
