Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, in particular to a high-efficiency screening mechanism of an extruder vibrating screen. Background Art

[0002] The vibrating screen operates by utilizing the reciprocating vibration generated by the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce a planar gyratory vibration, while the lower rotating weight causes the screen surface to produce a conical gyratory vibration. The combined effect of these two causes the screen surface to produce a complex gyratory vibration.

[0003] At present, when the vibrating screen vibrates, some materials often get stuck in the mesh of the screen. After completing all the screening work, the materials stuck in the mesh may enter the collection bucket used for the next layer of screening, resulting in affected screening efficiency. Secondly, the materials stuck in the mesh may also be retained on the screen and need to be manually removed to avoid affecting the next screening. Utility Model Content
