Plastic foam conveying equipment

Abstract

The invention relates to the field of plastic foam production, in particular to plastic foam conveying equipment which comprises a device main body. A first filter plate is movably installed at the upper end inside the device main body, a rotating column is fixedly installed at the left side inside the device main body, a bead grinding cylinder is fixedly installed at the left side inside the device main body relative to the outer side of the rotating column, and a baffle plate is fixedly installed inside the device main body relative to the upper part of the rotating column. A convex block isfixedly installed at the upper end of the first filter plate, and an inner shrinkage block engaged with the convex block is movably installed inside the upper end of the device main body, so that when the first filter plate is used for a long time and some raw material beads are clamped in the first filter plate, the first filter plate is driven to rotate with the lower end as the center by increasing the air exhaust speed of a fan, then, the rotating speed of the fan is reduced, the first filter plate returns under the effect of a right spring, the convex block collides with the inner shrinkage block to produce vibration with the certain frequency, the clamped raw material beads are vibrated out, and an automatic cleaning effect is achieved.

Description

technical field [0001] The invention relates to the field of plastic foam production, in particular to a plastic foam conveying device. Background technique [0002] Rigid foam plastic refers to the foam plastic that has no flexibility, high compression hardness, deformation when the stress reaches a certain value, and cannot return to its original shape after the stress is released. It is often used in related fields by using its heat insulation and mechanical properties. Now when producing hard plastics, it is necessary to first heat the raw material beads with steam to above 92°C to soften and foam, so that the internal blowing agent volatilizes and escapes the particles. The volume slowly expands to the required ratio or gram weight, and then the foam is heated by steam after a certain mold is filled, and can be fused into a molded product with a fixed shape. [0003] However, when the existing plastic foam raw material beads are transported, the size of the beads canno...
