Screening device for TPE plastic particle production

The utility model belongs to the technical field of plastic particle production and processing, and particularly relates to a screening device for TPE (thermoplastic elastomer) plastic particle production, which comprises a base. The multi-stage screening mechanism comprises a fixing box, electric push rods, a frame, a first screen, a second screen, an impurity box, pulleys, a sliding groove, a discharging block, a threaded rod, a clamping plate and a bearing, the fixing box is arranged on one side of the surface of the base, the sliding groove is formed in the other side of the surface of the base, and the two electric push rods are arranged in the fixing box; according to the plastic particle screening device, when plastic particles need to be screened, the particles to be screened are poured into the first screen, then the electric push rod is started to push the particles back and forth, and small particles fall into the second screen, so that screening of the particles is completed, and the problems that
