EPS foam board production line

Abstract

The invention discloses an EPS foam board production line. The production line comprises a spiral feeding machine (201), a quantitative discharging machine (202), a foaming machine (203), a fluidization drying machine (204), a curing box (205), a foam forming machine (206), a discharging and water removing device (207) and a conveying and drying system (208), and has the advantages that the spiral feeding machine conducts automatic bag cutting, discharging and recycling on raw material packaging bags, the labor intensity of workers is greatly relieved, quantitative discharging is carried out through the quantitative discharging machine, materials are premixed with steam while being discharged, foam particles are sequentially subjected to standing and curing in curing bins from top to bottom, and the foam particles stacked in the curing bins can be effectively ventilated through a silk screen exhaust cylinder. The foam particles can be effectively turned over while being transferred in the curing bins, formed foam plates are sequentially subjected to water stain cleaning on a buffering material receiving net and a conveying net belt, and the labor intensity of the workers is relieved.

Description

technical field [0001] The invention relates to the technical field of foam board production, in particular to an EPS foam board production line. Background technique [0002] At present, EPS foam boards are foamed by mixing and heating expandable polystyrene particles and steam. After foaming, they need to be aged in a well-ventilated curing box for 24 hours. The cured foam particles are heated by a molding machine. After pressing and forming, it is water-cooled, and then enters the drying room for drying. The structure setting of the existing EPS foam board foaming machine is not ideal, resulting in uneven heating of the foamed particles, which affects the foaming quality, and the existing curing box is a The simple air-permeable net bag is cured by natural ventilation, which leads to uneven curing of some parts, which affects the quality of the foam board. The water content of the formed foam board is relatively high, resulting in a long drying time. Contents of the inv...

The structure setting of the existing EPS foam board foaming machine is not ideal, resulting in uneven heating of the foamed particles, which affects the foaming quality, and the existing curing box is a The simple air-permeable mesh bag is cured by natural ventilation, which leads to uneven curing of some parts and affects the quality of the foam board. The water content of the formed foam board is relatively high, resulting in a long drying time
