Foamed decorating plate production device and method

Abstract

The embodiments of the invention disclose a foamed decorating plate production device and method. The foamed decorating plate production device comprises a discharging part, a segmented cooling part,a flattening part and a receiving part, wherein the discharging part comprises an extrusion die head for extruding a material body into a template prototype; and the segmented cooling part at least comprises an indirect cooling structure, a temperature rising structure and a blowing cooling structure which are sequentially arranged in the conveying direction. The production method comprises the steps that raw materials are mixed, heated and then cooled; after being subjected to extrusion molding, the mixed raw materials are cooled by a contact cooling structure, then sent into the temperaturerising structure to be reheated and then cooled by the blowing cooling structure; after being flattened by the flattening part, the cooled template prototype is pulled into the receiving part for cutting and receiving; the temperature of cooling water in the contact cooling structure is 40-60 DEG C; and in the reheating process, the temperature in the temperature rising structure is 80-85 DEG C. The effects that shrinkage deformation is avoided, the effectiveness of the cooling process is ensured, the physical and chemical properties are improved, and the product quality is improved are realized

Description

technical field [0001] The embodiments of the present invention relate to the technical field of foam board production, and in particular to a production device and method for foam decorative boards. Background technique [0002] Foamed board is a board with a honeycomb cross-section made of resin material as the main raw material and a foaming agent, especially PVC foamed board. [0003] The existing method is often similar to the hard plate, which is cooled and shaped after extrusion and then cut. However, because it has undergone a foaming operation, a fine honeycomb structure is formed inside, so its stability is relatively poor and its shrinkage rate is high. On this basis, the general production method is not only the internal honeycomb structure The uniformity of the pores cannot be guaranteed, and the plate itself is easy to shrink, deform or bend in the later stage due to various factors, resulting in unstable product quality.
