Honeycomb plate and its preparation, double steel belt continuous press and its cooling and shaping mechanism

Abstract

The invention discloses a cellular board and preparation thereof, a double-steel-strip continuous press and a cooling and forming mechanism. The cooling and forming mechanism is divided into an upper part and a lower part, wherein the upper part comprises a plurality of upper wallboards connected with a machine frame through connecting pins; a plurality of forming hydrocylinder are arranged on the upper wallboards and connected with the lower parts of the upper wallboards through connecting pins; the lower mobile end of each forming hydrocylinder forms a socket joint with a T shape of an upper forming plate; the lower part of the upper forming plate is fixedly connected with an upper cooling plate; the lower part comprises a plurality of lower wallboards which are respectively connected with the machine frame and a lower cooling plate through connecting pins; heat-conducting oil channels are distributed in the upper cooling plate and lower cooling plate; and the upper cooling plate and lower cooling plate are connected with an external coolant circulating system. The technical scheme has the advantages of reasonable structure and long service life, is convenient for installation and debugging, and greatly enhances the cooling efficiency, production efficiency and product quality. The thermoplastic cellular board produced by the production method and press has the advantages of stable cellular structure, favorable surface quality, high strength and large area.

Description

technical field [0001] The invention belongs to the field of manufacturing thermoplastic honeycomb panels, in particular to a double-steel-belt continuous press for producing thermoplastic honeycomb panels and its cooling and shaping mechanism, a production method using the press, and thermoplastic composites produced by the production method. Honeycomb panels. Background technique [0002] The patent document with the publication number CN102689458A discloses a thermoplastic honeycomb panel and its preparation method. The honeycomb body is formed by thermal bonding of double-layer composite pipes, and the honeycomb base material is formed by cutting the honeycomb body. The honeycomb base material is hot-pressed to make it The surface layer is melted to form a glue bump, which is large in size and has a high connection strength, which is much higher than the bonding strength between the outer layers of the pipe or the connection strength of the small surface glue bump formed...

AI Technical Summary

Problems solved by technology

However, the connection strength of thermoplastic honeycomb panels mainly depends on the rapid melting of the upper and lower ends of the surface layer to form glue bumps and timely cooling and shaping. However, the hot pressing process of the above-mentioned double-steel belt continuous press takes a long time. After hot-pressing and compounding the upper material layer between the moving rollers, it needs to be heated by the heating section, which will cause the heat to be transmitted to the inner core of the honeycomb base material and cannot be cooled in time, which will lead to the destruction of the honeycomb structure of the honeycomb plate and the surface of the honeycomb plate.
