Technical Field

[0001] The utility model relates to the technical field of vibrating screens, in particular to a vibrating screen for screening rubber pellets. Background Art

[0002] Vibrating screens are a type of mechanical equipment widely used across multiple industries. Their operating principle is based on the reciprocating vibration generated by a vibrator. The vibrator's upper rotating weight produces planar gyratory vibrations on the screen surface, while the lower rotating weight produces conical gyratory vibrations. The combined effect of these two factors produces complex gyratory vibrations on the screen surface. This vibration path is a complex spatial curve, with a circular projection on the horizontal plane and an elliptical projection on the vertical plane.

[0003] Upon investigation, the Chinese utility model patent with publication number CN208098566U discloses a plastic particle vibrating screen, which covers the frame with end covers, thereby reducing the plastic particles from bouncing onto the ground; however, during the screening process of the raw materials, the screen plate may be blocked by the raw materials, and staff need to clean it after a long time.
