Problems solved by technology

The molding process is complicated, the efficiency is low, and it is difficult to continuously and stably produce products on a large scale, resulting in poor quality and high cost, which reduces the competitiveness of the product
[0004] Extrusion splicing method: Extrude part of the honeycomb shape with an extruder, and then slice and assemble it into a board. The honeycomb board made by this method is hexagonal in shape, with good local strength and rigidity. Combined splicing instead of integral forming, so the overall strength and rigidity of the product are poor, and it is difficult to produce continuously on-line, so the production efficiency is low

Abstract

The invention discloses equipment and a production process for forming a cellular board by continuous extruding vacuum, belonging to the field of plastic forming. The equipment continuously extrudes a thermoplastic material through an extruding die head to form a hexagon cellular structure layer in a way of continuous vacuum plastic absorption; and in the continuous forming process, with the adoption of novel technology and production process, a sheet material is compounded on an upper surface, a lower surface or a single surface of the cellular structure layer on line.

Description

technical field [0001] The invention relates to equipment and a production process for continuously extruding vacuum-formed honeycomb panels, belonging to the field of plastic forming. Background technique [0002] Plastic hexagonal honeycomb panel is a kind of panel with light weight and high strength, and it has a wide range of market uses. Existing production techniques and methods cannot fully meet product performance requirements, and the price disadvantage limits market demand. So far, there is no process method that can realize continuous molding production. At present, the traditional molding methods of hexagonal honeycomb panels mainly include secondary bonding method and extrusion splicing method: [0003] Secondary bonding method: the sheet is formed now, and then according to the size of the hexagon, it is bonded at the grid of the sheet and then pulled apart to form a hexagonal honeycomb panel. The molding process is complicated, the efficiency is low, and it ...
