What Is Vibratory Bowl Feeder

Working theory of vibratory bowl feeder: There is a pulse electromagnet under the hopper, which can make the hopper vibrate up and down in the vertical direction. Due to the tilt of the shrapnel, the hopper twists and oscillates around its vertical axis. The parts inside the hopper are subjected to this vibration and rises up along the spiral track and then to the next process: the linear hopper vibrates to and fro linearly whereas the cylindrical vibrates to and fro torsionally. It is mainly driven by a vibration motor. When the vibration motor works, it generates a directional frequency force. Think of the vibrating bowl feeder as a bevel, and then analyze the physical force of the bevel, you can easily understand its working theory. When the electromagnetic coil of vibrating bowl feeder is in operation, the bevel will slightly up and down because of the electromagnetic force, and 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 to make the workpieces move from bottom to top along the spiral track, and are automatically oriented until they enter the feed chute from the upper output. And then they are sent to the corresponding worker by the feeding mechanism.

Due to the attraction of the electromagnet and the reverse resetting action of the supporting spring, the trough generates high-speed, high-frequency (50~100 times/second) and micro-amplitude (0.5~1mm) vibration, which move toward the workpieces to the top. As a result, this is the working process of the vibratory upper feeder.

When I=0, the trough is reset to the upper right by the support spring, and the workpieces move to the upper right with the friction of the rail and is gradually accelerated.

When I>0, the trough moves to the lower left under the attraction of the electromagnet, and the workpieces deviate from the orbit due to inertia, and continues to move to the upper right (slip or jump).

Over and over again → the workpieces move from bottom to top on the track.
