Description

TECHNICAL FIELD

[0001] The utility model relates to the field of plastic processing, especially relates to a screening device for PE pipe raw material particle production. BACKGROUND

[0002] Plastic particles refer to granular plastics, which are generally divided into more than 200 kinds and subdivided into thousands of kinds. The volume of plastic particles after cutting is large or small, so it is necessary to use a screening device to separate the powder particles that do not meet the standards, so as to improve the processing quality of plastic particles.

[0003] The screening device generally uses a vibrating screening machine. Its principle is to realize screening work by moving the screen mesh driven by the vibrating motor. The screen mesh is mostly installed on the support through four springs. However, when receiving the material, the material at the end of the discharge port is bounced and splashed due to the fluctuating vibration of the screen mesh in a vibrating state, resulting in some of the material not being able to smoothly enter the receiving container and scattering on the bottom surface. Therefore, the post staff needs to clean up, increasing the workload. UTILITY MODEL CONTENT
