[0002] When the spiral finishing machine is working, the workpieces to be ground and polished must be added in batches, and the vibration motor and vibration spring are used to drive the workpieces and abrasives in the working groove to vibrate. The working groove of the spiral finishing machine is arranged in a spiral shape, so that the abrasive workpiece can move in the spiral working groove, thereby achieving the purpose of grinding and discharging. At the same time, a screening mechanism is installed on the spiral finishing machine to separate the workpiece and the abrasive, and the abrasive can flow back into the working groove.

The workpiece is discharged from the discharge port, and the abrasive falls downward into the working groove.

[0004] In the above scheme, the spiral working trough discharges materials from its innermost circle, so that the sorting screen spans the radius of the working trough, and the filter holes set on the sorting screen also span the radius of the working trough, so that the abrasive filtered by the sorting screen will enter each circle of the working trough, further reducing the abrasive content in the outermost circle of the working trough. The workpiece is put into the outermost circle of the working trough through the workpiece adding port. When the abrasive is reduced, the polishing effect of the workpiece will be affected. For this reason, we propose a screening mechanism and a spiral finishing machine. Utility Model Content
