What is a vibrating bowl feeder?

Operating principle of vibrating bowl feeder: Under the hopper there is a pulsed electromagnet, which can make the hopper vibrate up and down vertically due to tilted shrapnel, the hopper will twist and oscillate around the vertical axis of the tubes. part. The inside of the funnel is subjected to this vibration and rises along the spiral and then comes the next process: the linear funnel vibrates back and forth linearly while the cylinder vibrates back and forth. It is mainly driven by a vibration motor. Vibration motor works, it generates a directional frequency force. Consider the vibrating bowl feeder as a bevel, then analyze the physical force of the bevel, you can easily understand its working theory when the electromagnetic coil of the vibrating bowl feeder is working. , the bevel angle will rise and fall slightly due to the electromagnetic force, then the operating frequency and clearance of the vibrating bowl feeder can be adjusted to achieve smooth operation.

Under the action of the electromagnetic vibrator, the hopper vibrates up and down, causing the workpieces to move from bottom to top along the spiral and be automatically oriented until they enter the feeding chute from the upper outlet. respective workers according to the feeding mechanism.

Due to the attraction of the electromagnet and the reverse reset action of the support spring, the trough produces high-speed, high-frequency (50 ~ 100 times/second) and micro-amplitude (0.5 ~ 1mm) vibrations. , move towards the workpiece upwards. As a result, this is the working process of the upper vibrating feeding unit.

When I=0, the chute is reset to the upper right by the support spring and the workpiece moves to the upper right by the friction of the rail and is gradually accelerated.

When I>0, the chute moves down to the left under the attraction of the electromagnet, the workpiece deviates from the orbit due to inertia and continues to move up to the right (slide or jump).

Iteratively → the workpiece moves from bottom to top on the rail.
