A fully automatic thermocompression forming device for multi-layer composite epoxy glass fiber board

Abstract

The invention discloses a fully automatic hot-press forming device for multi-layer composite epoxy glass fiber boards, which comprises a spinning assembly and a tray on which the composite boards to be hot-pressed are placed, the spinning assembly has a rotary drive, and the spinning The assembly applies heat while applying pressure to the upper surface of the composite sheet. The active action of the spinning assembly is only one rotary motion. A roller is set on the upper surface of the composite sheet through multiple connecting rods. The roller presses the upper surface of the composite sheet and rolls and applies pressure to maintain the pressed state. Then the spinning assembly can also be carried out. Heat generation, heat the composite board at the contact position on the upper surface of the other composite boards, the glued material inside the composite board will glue the composite boards into one, at the same time of gluing, the surface of the composite board can also be pre-set with a layer of release film, the hot pressing process Attached together to the composite sheet.

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 ...

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
