The electromagnetic vibrating feeder uses an electromagnetic exciter to drive the tank to vibrate reciprocally at a certain inclination angle, so that the material moves along the tank.
The vibration capability of the electromagnetic vibrating feeder comes from the electromagnetic exciter. After power is turned on, the electromagnet and electric coil in the electromagnetic vibrator generate an exciting force that is damped by the shock absorber and then transmitted to the feed trough by the armature, connecting fork and other structures. body, causing the entire machine to produce forward and backward reciprocating and throwing motions, thereby realizing self-feeding of the equipment.
Control method of electromagnetic vibrating feeder
The so-called control of electromagnetic vibrating feeder refers to the adjustment of the output of electromagnetic vibrating feeder.
Adjust amplitude of the electromagnetic vibrating feeder
- The vibration amplitude of the electromagnetic vibrating feeder determines the intensity of the vibration force acting on the transported materials. Different materials have different properties, such as particle size, density and flowability.By adjusting the amplitude, the flow rate and density of material discharged from the feeder can be controlled to meet the specific requirements of the material being processed. Higher amplitudes produce stronger vibrations that can be used to convey larger quantities of material or overcome any resistance to material flow.
- This is usually achieved by adjusting the size of the electromagnetic excitation force, because the amplitude of the electromagnetic vibrating feeder is proportional to the electromagnetic excitation force;
Adjust working point of the electromagnetic vibrating feeder
Because vibrating feeders generally work in a near-resonant state, as long as the frequency ratio is slightly adjusted, significant changes in amplitude can be caused.
Adjusting the working point of an electromagnetic vibrating feeder involves setting parameters such as voltage, frequency, and amplitude to achieve the desired feeding performance.
- Voltage Adjustment: The voltage supplied to the electromagnetic coil determines the strength of the magnetic field generated, which in turn affects the amplitude of vibration. Increasing the voltage increases the amplitude, while decreasing it reduces the amplitude. Adjust the voltage based on the desired feeding rate and material characteristics.
- Frequency Adjustment: Some electromagnetic vibrating feeders have frequency controllers that allow you to adjust the frequency of the electrical supply to the coil. Changing the frequency alters the speed and intensity of the vibrations. Experiment with different frequencies to find the optimal setting for your application.
- Amplitude Adjustment: Adjusting the amplitude directly affects the magnitude of the vibratory motion produced by the feeder. This is typically achieved by controlling the current supplied to the electromagnetic coil. Increase the amplitude for higher material flow rates or to overcome material flow resistance, and decrease it for finer control or to prevent material segregation.
The role of the control system of electromagnetic vibrating feeder
The control system of an electromagnetic vibrating feeder plays a crucial role in regulating and optimizing its operation. Here’s an overview of its components and functions:
- Controller: The controller serves as the central unit of the control system. It receives input signals and commands from various sources and generates output signals to regulate the operation of the feeder.
- Power Supply: The power supply provides electrical energy to the electromagnetic coil of the vibrating feeder. It ensures that the coil receives the necessary voltage and current to generate the magnetic field required for the vibratory motion.
- Frequency Controller: In some systems, a frequency controller is used to adjust the frequency of the electrical supply to the electromagnetic coil. By varying the frequency, the controller can control the amplitude and intensity of the vibrations produced by the feeder.
- Amplitude Controller: The amplitude controller regulates the magnitude of the vibratory motion generated by the feeder. It adjusts the current supplied to the electromagnetic coil, thereby controlling the strength of the magnetic field and the resulting amplitude of vibration.
- Feedback Sensors: Feedback sensors are used to monitor various parameters of the feeder, such as vibration amplitude, material flow rate, and power consumption. These sensors provide real-time data to the controller, allowing it to make adjustments and optimize the feeder’s performance.
- Safety Interlocks: Safety interlocks are integrated into the control system to ensure safe operation of the feeder. These may include sensors to detect overloads, overheating, or material blockages, as well as emergency stop buttons to halt operation in case of an emergency.
Conclusion
Overall, the control system of an electromagnetic vibrating feeder integrates various components and functionalities to regulate the feeder’s operation, optimize performance, and ensure safe and efficient material handling.
