目前,国内采用以振动电机为激振动力源的给料机都是单质体的惯性振动给料机。这种给料机的定向性能好,噪音小,设计、制造简单;但其缺点是所需的激振力大、振动电机的容量较大。为了避免其缺点,可以把电机振动给料机设计成双质体共振式的。图1和图2是这种给料机的两种结构型式。图1中,电机联接板3实 At present, the domestic use of vibrating motor as the motive power source feeder are single mass inertial vibrating feeder. This kind of feeder has good directional performance, low noise, simple design and manufacturing; however, the disadvantage is that the required exciting force is large and the capacity of the vibration motor is relatively large. In order to avoid its shortcomings, the motor vibration feeder can be designed as double mass resonance type. Figure 1 and Figure 2 are two types of feeder structure.
