Glue solution circulation equipment used for large-scale honeycomb core glue dipping technology

Abstract

The invention relates to glue solution circulation equipment used for a large-scale honeycomb core glue dipping technology. The glue solution circulation equipment comprises an inner circulation system and an outer circulation system of a glue tank, wherein the inner circulation system of the glue tank is characterized by comprising the glue tank, a temperature sensor, a liquid sensor and a circulation pipeline. The outer circulation system of the glue tank is characterized by comprising a raw agent tank and a liquid level sensor, a raw glue tank and a liquid level sensor, a glue mixing tank and a liquid level sensor, a temperature sensor, a movable tank car, a pneumatic valve, a glue supplementary tank, a glue return pump and the like. According to the automatic glue solution circulation equipment, the time needed for uniformly mixing a glue solution is short, the efficiency is high, the manual cost can be reduced, the operation is simple and convenient, the automation degree is high, the temperature, liquid level and viscosity of the glue solution of the glue tank can be automatically controlled, and the requirement for efficiently and uniformly impregnating large honeycomb cores in batches is satisfied.

Description

technical field [0001] The invention relates to a glue liquid circulation equipment used in a large-scale honeycomb core glue dipping process. Background technique [0002] Aramid honeycomb core Aramid honeycomb core is light in weight, high in strength, flame retardant, and good in dielectric properties. As a special sandwich material, its application in aerospace, transportation, construction and other fields is gradually expanding. The manufacturing process of the honeycomb core includes: glue coating, hot pressing, edge trimming, stretching, shaping, dipping, curing, and slice cutting. The dipping process of the white honeycomb after shaping determines the density distribution and color uniformity of the honeycomb after curing, which plays a very key role, and whether the viscosity of the dipping glue is uniform is a direct factor for the amount and uniformity of the large honeycomb block. At present, the size of the honeycomb core can be as high as 914mm, as long as 26...

AI Technical Summary

Problems solved by technology

At present, the size of the honeycomb core can be as high as 914mm, as long as 2620mm, and as wide as 1350mm. The amount of glue required is large. The resin used for honeycomb impregnation will be inconsistent with the viscosity of the upper layer and the lower layer under the condition of standing for a long time. Phenomenon, the current process generally adopts the method of manual stirring to ensure the uniformity of the glue, but this method is labor-intensive, takes a long time to configure, and has little effect, and cannot meet the production requirements of uniform impregnation of large honeycomb
