Reformation of feeder drives

1. Separate experiment of vertical drive vibrating feeder

Carry out a separate test from the optimal combination to analyze the relationship between voltage, feeding speed, amplitude and frequency. The feeding speed is measured by the number of materials fed per 10s, and the amplitude is measured by the amplitude value at the edge of the tray perpendicular to the surface of the tray.

2. The relationship between voltage and feeding speed

When the frequency reaches the natural frequency of the vibrating feeder 127HZ, the applied voltage starts from zero and gradually increases until 120V, then the vibrating feeder starts to feed slowly, and the voltage is added to the maximum range of 240V, and the recorded data can be seen , When the voltage is less than 120V, the feeding cannot be realized, because the power is too small, the deformation of the double chip is too small, and the material tray cannot be driven to achieve stable conveying. When the voltage is greater than 120V, the material begins to fall, and as the voltage increases, the feeding The speed gradually increases, and when the voltage reaches 180V, when it increases again, the feeding speed has no obvious increasing trend.

3. The relationship between frequency and feeding speed

Frequency is a relatively important parameter of the vibrating feeder. After the prototype machine is processed and assembled, its natural frequency is a fixed value. According to the results of finite element analysis data, its natural frequency is 120HZ, but because the analysis ignores the structure It is inevitable that there will be deviations due to the influence of the connecting part of the connection part and the material of some parts. This requires experiments to measure its natural frequency. Since the natural frequency is one point at a time, it is difficult to measure it more accurately, so we can use it according to its work. The principle is that when it reaches the natural frequency, it realizes resonance, and the amplitude is the largest. At this time, the feeding speed is the largest. We can approximately find its natural frequency through the experimental data measured by the experiment. When the frequency reaches 130HZ, the feeding speed is the largest, so we can approximate its natural frequency to be around 130HZ.
