Problems solved by technology

In addition, the adjustment accuracy is poor. It is difficult to adjust the eccentricity to achieve the optimal excitation force parameter during work. It can only be "close" or "almost", and it is impossible to dynamically adjust the excitation force during work.
Another disadvantage of the traditional vibrator is that when the workpiece requires a large excitation force, it must be adjusted to a large eccentricity when it stops.
Start the excitation motor under a large eccentricity. Due to the large starting load, the current of the excitation motor increases, and it is easy to burn the electrical components or damage the motor.

Description

technical field [0001] The invention belongs to the technical field of vibration machinery, and in particular relates to an exciter installed on vibration machinery equipment. Background technique [0002] The exciter is a device installed on the vibration mechanical equipment to generate the exciting force. It is the main component of the vibration machine and plays a decisive role in the vibration mode of the machine. Vibrating machines equipped with exciters are widely used in metallurgical mines, industrial production, engineering construction, and experimental equipment to achieve screening, transportation, compaction, vibration aging, and forming of objects. At present, the existing mechanical exciter is mainly composed of a motor and an eccentric vibrator, and the motor drives the movement of the eccentric vibrator to generate mechanical vibration. This kind of vibrator can only control the vibration frequency by controlling the rotating speed of the vibrating motor,...
