Description

Technical Field

[0001] The utility model belongs to the technical field of plastic particle processing, and particularly relates to a novel plastic particle screening machine. Background Art

[0002] Plastic particles refer to granular plastics, generally divided into more than two hundred types, and can be subdivided into thousands of types. Common plastic particles are divided into general plastics, engineering plastics and special plastics. A screening machine is a vibrating screening mechanical equipment that uses the relative movement between bulk materials and the sieve surface to make some particles pass through the sieve holes and classify materials such as sand, gravel, and crushed stones according to particle size. During the processing of plastic particles, a screening machine is usually required to classify particles of different sizes.

[0003] A Chinese patent discloses a plastic particle screening machine (CN221161156U), which relates to the technical field of plastic particle processing machinery. It improves the problem that the surface structure of the electric sieve mesh is simple, and some plastic particles slide down along the slope of the sieve mesh in a piled-up state under the action of their own gravity, which is likely to cause the phenomenon of missed screening and reduce the screening quality. It includes a frame and an electric sieve mesh. The electric sieve mesh is installed inside the frame and is inclined. An electric control box is installed on the outer wall of the frame. A material spreading component is erected above the electric sieve mesh. A metal screening component is installed at the feeding end of the frame. During the screening process of the electric sieve mesh in this application, the reciprocating electric push rod drives the push plate to make a reciprocating movement relative to the surface of the electric sieve mesh. The ceramic seat at the bottom of the rubber column of the push plate conducts spreading and blocking treatment on the plastic particle materials, effectively dispersing the materials and reducing the phenomenon of missed screening, and improving the screening quality. During the processing of plastic particles, agglomeration will occur. During the subsequent screening process, the agglomerated plastic particles cannot be screened out, so they will accumulate in the screening machine, which is likely to reduce the screening efficiency and screening quality of the screening machine. Therefore, a novel plastic particle screening machine is provided. Summary of the Utility Model
