Description

Multistage sorting unit of plastic granules Technical Field The utility model belongs to the technical field of plastic manufacturing, and particularly relates to a multistage sorting device for plastic particles. Background With the rapid development of the plastic processing industry, the requirements on the precision and purity of plastic particles are higher and higher, and the multistage sorting device plays a crucial role in the plastic particle production process. Traditional sorting unit adopts the mode of reel vibration generally, makes the inside material of frame screen out under the vibratory action to realize the separation of material. However, the prior art vibrating screen sorting apparatus has some significant problems. First, the vibration frequency and vibration amplitude are two key factors that affect the effectiveness of frame sorting. Too high or too low vibration frequency can lead to the failure of effective separation of materials and influence the separation precision. The vibration amplitude is too large, so that the material is easy to jump, the sorting is uneven, and the material cannot be effectively pushed to advance due to the too small vibration amplitude, so that the sorting efficiency is reduced. In addition, the plastic granules of different specifications are different to the demand of vibration frequency and range, and current device often is difficult to carry out nimble adjustment according to material characteristic, leads to selecting separately the effect not good. Meanwhile, the problems of fatigue, loosening and the like of a screen frame structure can be caused by long-term vibration operation, and the stability and reliability of sorting are further affected. Therefore, a multi-stage sorting device for plastic particles is needed to improve the sorting effect and meet the high standard requirements of the modern plastic processing industry.
