Description
Technical Field

Background
In the initial stage of the production process of the epoxy glass fiber board, uniform thermosetting resin glue solution is required to be coated on the surface of glass fiber cloth, and then the subsequent processes of drying, semi-curing, cutting, hot-pressing curing and the like are carried out.
In the process of smearing the resin glue solution on the glass fiber cloth, the very important point is that air bubbles cannot be accumulated in the glass fiber cloth, otherwise the electric performance of a finished glass fiber board is influenced, the glass fiber cloth is formed by interweaving glass fibers, the surface of the glass fiber cloth is provided with a plurality of gaps, air accumulated in the gaps cannot actively and completely overflow when the glass fiber cloth is immersed in the resin glue solution, and a plurality of gases can be remained to occupy space positions to form cavities, in the prior art, the treatment on the bubbles in the cavities is generally realized by brushing the resin glue solution for a plurality of times, the efficiency is lower, the degassing rate is not greatly improved, CN104275271A provides a novel device for improving the soaking effect of the glass fiber cloth, the glass fiber cloth is led into a shell with different liquid pressures on two sides, so that the resin glue solution passes through the glass fiber cloth under the action of the pressure difference, the degassing efficiency is improved, but the degassing cannot be ensured fully, because the pressure difference between the two sides of the glass fiber cloth is not very large, even if the pressure difference is initially very large, the pressure difference between the two sides becomes small after part of the glue solution passes through the glass fiber cloth, the flow caused by the pressure difference can preferentially select the position with smaller passing resistance, namely the position which is passed through by the glue solution, the position where the bubbles are left still has larger over-flow resistance and does not allow the glue solution to pass through, the bubbles stay on the glass fiber cloth because the gas mass is adsorbed on the glass fiber structure, and the adsorption force of the gas mass is equal to the pressure difference force resisting the two sides, so the proposal can not ensure sufficient impregnation degassing.

and then, the glass fiber cloth reaches the position of the exhaust brush, and the exhaust brush brushes the resin liquid near the surface of the glass fiber cloth to generate flow, so that the gas which is not floated in the glass fiber cloth is more easily hooked.
Furthermore, the floating wheel group comprises a first connecting rod, a second connecting rod and a brush wheel, one end of the first connecting rod is hinged to the inner wall of the shell, the other end of the first connecting rod is connected with one end of the second connecting rod in a sliding manner, the other end of the second connecting rod is hinged to the brush wheel, the brush wheel is respectively abutted against two sides of the glass fiber cloth, and the whole density of the brush wheel is smaller than that of the resin liquid. The brush wheel is hung on the first connecting rod and the second connecting rod, the brush wheel floats on the resin liquid, when the liquid level of the resin liquid descends, the first connecting rod and the second connecting rod sliding sleeve are elongated, the brush wheel descends and still clings to the glass fiber cloth, the liquid inlet position of the glass fiber cloth is guaranteed to be blocked by the brush wheel, the glass fiber cloth descends, the brush wheel rotates along the surface of the glass fiber cloth due to friction, bubbles emerging after the glass fiber cloth is immersed in the resin liquid float upwards, when the glass fiber cloth reaches the surface of the brush wheel, the bubbles are scraped away by the brush wheel, the resin liquid is separated out from the positions far away from the two sides of the glass fiber cloth, and the position where the glass fiber cloth enters the resin liquid is stable.
