Description

TECHNICAL FIELD

[0001] The utility model relates to the field of vibrating screen, especially a novel vibrating screen. BACKGROUND

[0002] When producing plastic particles, first, raw materials are prepared, then extruded by a screw extruder, and the extruded plastic strip is cooled and then crushed into a particle shape.

[0003] When plastic particles are crushed into a particle shape, a vibrating screen is needed to screen the plastic particles. The existing vibrating screen is usually composed of a vibrating machine tool, a vibrating motor and a screening net, so that after the plastic particles are processed by the screening machine, powder and excessively long plastic particles are screened out, thereby ensuring the quality of plastic particle production.

[0004] However, when screening plastic particles, the vibrating screen uses a vibrating method to screen plastic particles, so that the powder particles mixed in the plastic particles will be scattered into the air due to the vibration of the vibrating machine tool, which not only causes waste of plastic powder, but also pollutes the air, thereby having certain defects.
