Full-automatic hot press molding device for multi-layer composite epoxy glass fiber plate

Abstract

The invention discloses a full-automatic hot press forming device for a multi-layer composite epoxy glass fiber plate. The full-automatic hot press forming device comprises a spinning assembly and a tray; the composite plate to be subjected to hot-press forming is placed on the tray; the spinning assembly is provided with a rotary drive; the spinning assembly heats the upper surface of the composite plate while applying pressure to the upper surface of the composite plate; only one rotary motion is adopted in the active action of the spinning assembly; a roller is arranged on the upper surface of the composite plate through a plurality of connecting rods; the roller presses the upper surface of the composite plate and conducts rolling pressure application to keep a press-fit state; then the spinning assembly can further conduct heating to heat the other contact positions of the upper surface of the composite plate; the composite plate is glued into a whole through a gluing material in the composite plate; a layer of release film can be further arranged on the surface of the composite plate in advance during gluing; and the release film is attached to the composite plate in the hot pressing process.

Description

technical field [0001] The invention relates to the technical field of lamination of composite epoxy glass fiber boards, in particular to a fully automatic thermocompression forming device for multilayer composite epoxy glass fiber boards. Background technique [0002] Multi-layer composite epoxy glass fiber board is a commonly used living board, which is widely used in buildings for decoration and functional isolation. [0003] The more important step in the production process of composite panels is to press the single-layer panels. Before pressing, apply glue between the composite layers. After the layers are assembled, put the panels to be hot-pressed into the hot-pressing device for For molding operations, for some high-end products, it is also necessary to lay a layer of release film on it for packaging, transportation, and protection before use. [0004] In the prior art, the hot-pressing process of the composite board is generally carried out by gravity pressing and ...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the hot-pressing process of the composite board is generally carried out by gravity pressing and providing a heating environment, that is, the laminated composite board is pressed by a heavy object and then placed in a heating box for heating to realize the hot-pressing process. Although the hot-pressing method can guarantee the hot-pressing quality, the hot-pressing efficiency is low and continuous production is not possible, and the plates need to be manually fed into and taken out of the heating box, and heavy objects also need to be transferred;

[0005] In the prior art, some pressure rollers are used for hot pressing operations. However, simple pressure rollers can only run on a specific track. For plates of different lengths and sizes, the adaptability is not strong, and some pressure rollers are carried out around an installation shaft. Then put the composite sheet on a set of springs. When the pressure roller revolves around the installation shaft, it will press down on the spring to keep the contact between the pressure roller and the composite sheet. However, in this way, the downward pressure of the pressure roller on the composite sheet varies greatly. Moreover, in order to be able to hot-press a longer composite sheet, the revolution length of the pressing roller also needs to be lengthened accordingly, so that the height of the composite sheet varies greatly, and a large height variation means a large change in the downforce, which is not conducive to composite Uniform hot pressing of sheets
