Adjusting the vibration magnitude of the electromagnetic vibration feeder can be done by following the following steps:
Learn about the main structure and performance of electromagnetic vibratory feeders. This includes the electromagnetic shaker, controller, and coil, which together determine the vibration performance of the electromagnetic vibrating feeder.
Adjust the frequency and amplitude of vibration. The frequency adjustment usually needs to be decided according to the working environment and the characteristics of the material, and the frequency should be lowered when the material is viscous, and the frequency should be adjusted higher if it is not. The adjustment of vibration amplitude involves adjusting the distance of the electromagnetic shaker and the size of the output voltage in the controller, the farther the distance, the greater the vibration amplitude; The higher the output voltage, the greater the amplitude of vibration.
Adjust the stiffness of the spring plate pack. After the adjustment work of the whole machine is completed, you can start to adjust the stiffness of the spring plate group. By loosening the access screw and turning on the control power, the operating current is gradually increased while the indication value of the amplitude indicator is observed. If the current reaches the maximum value and the amplitude does not reach the maximum value, the jacking screw of the spring plate group can be adjusted appropriately to achieve an increase in the amplitude.
Adjust the air gap. The air gap between the core and armature is critical to the proper functioning of the feeder. The air gap should be adjusted to 28±0.5mm, but be careful not to overdo it so as not to increase the current or damage the parts.
Adjust the set of spring plates connected by the double mass points. After the air gap adjustment is complete, you can start adjusting the spring plate set. Adjust the spring rate by looking at the amplitude indicator to achieve the best tuning value.
Check and adjust the damping springs. Due to the resonance frequency of the elastomer consisting of the vibrating feeder and the damping spring, there may be a transient oscillation during the start-stop process. Adjust the eccentric block phase of the damping spring to avoid resonance and ensure the proper operation of the device.
During the adjustment process, it is also necessary to pay attention to the layout of the electromagnetic vibration feeder to avoid material accumulation or bottleneck problems to achieve efficient production. At the same time, attention should be paid to maintenance and maintenance to ensure the stability and long-term service life of the equipment.
