AI Technical Summary

Technical Problem

The existing foaming machine for plastic foam production needs to discharge foam particles during the foaming process before the next foaming is carried out, resulting in a low foaming efficiency and thus reducing the production efficiency of plastic foam.

Method used

A foaming machine including a conveying mechanism, a heating mechanism and a screening mechanism is designed. The conveying mechanism realizes continuous transport and heating of polystyrene particles through spiral conveying leaves and electric heating tubes, forming foamed and expanded particles. The heating mechanism heats the conveying pipe through an electric heating tube, and the screening mechanism screens out particles that have not been expanded by heat through the mesh screen tube to facilitate subsequent foaming.

Benefits of technology

The continuous foaming process is achieved, the production efficiency of plastic foam is improved, and the frequency and time of foaming operation are reduced.
