Edge sealing method and device for thermoplastic cellular board

Abstract

The invention discloses an edge sealing method and device for a thermoplastic cellular board. The edge sealing device comprises a workbench, mold supports, hot molds, cold molds and linear driving mechanisms, wherein the mold supports are arranged at the two ends of the workbench correspondingly; the hot molds and the cold molds are arranged on the mold supports, arranged up and down, and provided with circular arc grooves matched with the thermoplastic cellular board in thickness; and the linear driving mechanisms are connected with the mold supports to drive the mold supports to move. The edge sealing method comprises the steps that the thermoplastic cellular board is placed at the preset position of the workbench; the hot molds are heated, the mold supports at the two ends are driven through the linear driving mechanisms, so that the hot molds are pushed to move forwards to make contact with the thermoplastic cellular board, and pressure is applied slowly to enable the thermoplastic cellular board to reach the specified position; and the hot molds are moved away, the hot-pressed thermoplastic cellular board is moved into the cold molds to be cooled and shaped, and edge sealing is achieved when the thermoplastic cellular board is taken out. According to the edge sealing method and device, two edges can be sealed simultaneously, so that the working efficiency is improved; the device is simple in structure and easy to operate; and according to the method, extra edge sealing bars and bonding agents are not needed, and the edge sealing effect is good.

Description

technical field [0001] The invention relates to the production field of thermoplastic honeycomb panels, in particular to an edge sealing method and device for thermoplastic honeycomb panels. Background technique [0002] Thermoplastic honeycomb panels have the advantages of light weight, high specific strength and specific stiffness, and are widely used in the construction industry, aerospace, automobile manufacturing and other fields, but their subsequent edge banding has always been a difficult point in the industry. [0003] Most of the current follow-up edge banding processes of thermoplastic honeycomb panels need to use additional edge banding strips for edge banding. Edge banding strips are compacted, but this method has low production efficiency and the strength of the edge after edge banding is not high, thereby affecting the quality of the honeycomb panel, and the prepared honeycomb panel also contains adhesives such as glue, which is not conducive to environmental ...
