Research and Analyzation on the Two-Symmetric-Point Vibration Source Piezoelectric Feeding Device

We designed a new type of multi-point piezoelectric vibrating feeding device and did some research on the transport properties of the two-symmetric-point vibration source devices. Meanwhile, we also analyzed all the factors influencing the velocity of the material-supplying device and indentified the working frequency and voltage, the basic linear relationship between voltage, installation angle-α and the device material-supplying velocity. The phase difference and anchor location can obviously influenced the material-supplying velocity. It worked well when used to deliver some materials with moderate fluidity, such as rice, washing powder, radix isatidis granules, thin salt and so on.
