Description

technical field [0001] The present invention relates to a gear transmission structure planetary gravity mixing and stirring device, in particular to a gear planetary gravity discretizer. Background technique [0002] In the field of condensed matter physics, new nanomaterials, semiconductors, chemicals, medicines, coatings and adhesives and other industries, it is often necessary to quickly mix and stir several raw materials, and sometimes it is necessary to mix and defoam simultaneously. Generally, non-mechanical contact stirring adopts the form of automatic speed change, and its vacuum processing is not conducive to the processing of heat dissipation and sealing. Chinese patent 2010 2 0124347.4 discloses a "planetary gravity discretizer", which includes a stepless balance adjustment mechanism, a frame, a motor, a tray driven by the motor, a cup holder connected to the tray and connected to the motor through bearings. The speed-regulating coupling wheel on the rotating sha...

Problems solved by technology

This patent can facilitate the mixing and degassing of several raw materials. The existing problem is that the self-rotating speed-regulating drive adopts a belt device. When the device is working, due to factors such as belt elongation and aging, the transmission ratio fluctuates, resulting in poor stirring performance. Stablize

The motor is directly connected under the working tray, resulting in unfavorable heat dissipation and long-term accumulation of heat, resulting in some damage to the properties of the stirred material

Moreover, due to this structure, the vacuum sealing link is unreliable, and under long-term use conditions, it is easy to cause the function of the sealing element to lose
