Composite vacuum impregnation device and impregnation method

Abstract

The invention discloses a composite vacuum impregnation device and an impregnation method. The device comprises a material conveying end shell and a vacuum pump, a material conveying connecting pipe is fixed to the surface of the left side of the material conveying end shell, a discharging connecting pipe is arranged below the material conveying connecting pipe, an adjusting wheel is arranged on the surface of the front side of the material conveying end shell, and a pressure gauge is installed at the right side of the adjusting wheel. A sealing cover is fixed to the right end face of the material conveying end shell, a cooling pipe is arranged on the surface of the front side of the sealing cover, an immersion end is fixed to the bottom side of the sealing cover, a material channel is arranged under an immersion rotating shaft, a turnover end is arranged at the rear end of a material box, and a communicating pipe is connected to the surface of the rear side of the material conveying end shell. When the internal environment is pumped again through a pressure gauge and the material conveying end shell to reach the vacuum state, the pumping condition of internal air can be judged according to the numerical value of the air pressure gauge, colloid can automatically flow inwards under the action of pressure through the internal vacuum, and meanwhile the vacuum state of the whole internal environment is guaranteed.

Description

technical field [0001] The invention relates to the technical field of vacuum dipping devices, in particular to a vacuum dipping device and a dipping method for composite materials. Background technique [0002] Dipping impregnation The surface of rayon, synthetic fiber and glass fiber cord is smooth, and the adhesion between rubber and fiber can be significantly improved after dipping. The commonly used immersion solution is an aqueous emulsion of natural latex and resorcinol formaldehyde resin. The glue service equipment includes a stain tank, a drying room, a hot sheet and a coiling device, and can also be connected with a calender to form a joint production line of dipping, pasting, and glue wiping. The utility is based on the problems encountered during use Improve on the original basis. [0003] During the use of the dipping device on the market, it is not conducive to maintaining the vacuum state of the internal space, and it is easy to affect the quality of the col...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a vacuum dipping device and dipping method for composite materials, to solve the problems in the above-mentioned background technology that are not conducive to maintaining the vacuum state of the internal space, and easily affect the quality of the colloid. When filling materials, it is necessary to make the interior The space reaches a vacuum state again. When the interior is in a vacuum state, the outer wall of the container is easily deformed by the pressure. The high temperature of the sealed space is not conducive to the storage of the colloid. The quality of the finished product is affected by the uniformity of the surface coating.
