Plastic particle screening device

A plastic particle screening device comprises a fixing frame, the bottom of the fixing frame is fixedly connected with a connecting frame, the bottom of the connecting frame is provided with an open hole, the interior of the fixing frame is fixedly connected with a supporting frame, the interior of the supporting frame is provided with an arc frame, the bottom of the arc frame is fixedly connected with a fixing plate, and the arc frame is fixedly connected with a first motor. Compared with the prior art, the plastic particle screening device has the advantages that the second motor drives the screening frame to rotate, so that plastic particles are subjected to secondary screening, chippings and some impurities existing in the plastic particles are screened out, and the situation that the chippings and some impurities affect the subsequent plastic production quality is avoided; and after screening is completed, the collecting frame is taken out, a baffle is controlled to ascend and descend through an electric
