1. The vertical drive type vibrating feeder experiment separately
By the optimal combination for a separate test, analysis of voltage, feeding speed, the relationship between the amplitude and frequency. In every 10 s, the feeding speed feeding number to meter, amplitude in the plate edge is perpendicular to the material on the surface of the disc amplitude value to gauge.
2. The relationship between the voltage and the feeding speed
When the frequency of natural frequency of the vibrating feeder 127 hz, the applied voltage starting from scratch, gradually increase up to 120 v, began to slowly feeding vibrating feeder, have been added to the maximum range of 240 v voltage, record the data, it can be seen that the voltage is less than 120 v can’t realize feeding, because power is too small, double the deformation of the chip is too small, can’t drive disc reach stable feeding, when the voltage is greater than 120 v, the material began to fall, and with the increase of voltage, the feeding speed increases gradually, when the voltage of 180 v, increase again, feeding speed there is no obvious increase trend.
3. The frequency and the feeding speed
Frequency vibrating feeder is one of the more important parameters, when the prototype after processing and assembling, it is the natural frequency of a fixed value, we according to the results of finite element analysis of data, according to its inherent frequency is 120 hz, but because the analysis ignores the connection part of the structure and the influence of some parts material, hard to avoid can have deviation, which requires the experiment to determine its natural frequency, due to the natural frequency is a it’s very hard a point more precisely, so we can according to its working principle, reached its natural frequency, resonance, maximum amplitude, the feeding speed of maximum at this moment, we can through the experiment of measurement data approximate to find its natural frequency. When the frequency of 130 hz, the feeding velocity so that we can get the inherent frequency approximation for around 130 hz.
