For application of the axial vibration micro feeding technology to the quantitative dispensing of an implant control releasing drug micro system, an experimental apparatus based on the axial vibration method was set up. By using a glass capillary hopper and a conical plastic-tip as the dispending tubes, the vibration amplitude between both dispending tubes was researched and the influences of quantitative dispensing control parameters on the starting vibration amplitude, powder flow rate and the powder flow stability were discussed. The results show that the conical plastic-tip is a better dispensing tube with stable dispensing and good resistance to plugging. The higher the frequency, the lower the starting vibration amplitude needed to achieve desired starting feeding. At a constant excitation frequency, the flowing powder in the tube increases with the flow rate first, and then decreases to a stable value, meanwhile being a full flow state. Under both conditions with the excitation frequencies of 50 Hz, 150 Hz and the amplitude between 200-300 μm and 35-50 μm, the maximum and stable powder flow rate can be obtained. It concludes that the axial vibration micro feeding technology can achieve stable, accurate dispensing of the drug powder.
