Description

Screening material return guide equipment for EPS hot melt granulation production Technical Field The utility model relates to the technical field of granulation production, in particular to screening material return guiding equipment for EPS hot melt granulation production. Background EPS (expandable polystyrene) hot melt granulation production is a process of recycling waste EPS foam plastics into granules through hot melting, extrusion, cutting and other processes. After the plastic particles are extruded, the plastic particles need to be collected by using a receiving device, and at present, part of devices can screen the plastic particles, but the plastic particles on a screening net cannot be discharged in time, so that the screening of the particles is influenced; In order to solve the problems, the specification discloses a receiving device for plastic extrusion granulation, which is searched, wherein the publication number is CN221187221U, and the receiving device is recorded in the specification, wherein plastic particles enter a shell through a receiving hopper and then fall on a sieve plate, so that the plastic particles can move along the sieve plate, the plastic particles are screened through sieve holes on the sieve plate in the moving process, qualified products can flow into a second collecting frame along the sieve plate, unqualified products fall into a first collecting frame through the sieve holes on the sieve plate, and therefore continuous screening is performed, and the screening efficiency is improved; However, the material receiving equipment for granulation still has certain defects in the practical application process, for example, in the technical scheme, although the qualified and unqualified granular materials are respectively sorted and collected through the second collecting frame and the first collecting frame, the recovery processing link of the unqualified materials is insufficient, an automatic return guide device is not arranged in the system, and therefore operators need to stop the machine and manually pour the unqualified materials into a feed inlet again for secondary screening processing.
