Embodiment Construction

[0011] A detailed description of one embodiment of the invention is provided by way of example only and with reference to the following figures, which are simplified schematic diagrams illustrating the basic structure of the embodiment only.

[0012] Depend on figure 1 and figure 2 It can be seen that the glue circulation equipment in the honeycomb gluing process is composed of a solvent tank 1 , a mixing tank 6 , a gluing tank 8 , a pneumatic diaphragm pump 11 , and a viscosity sensor 10 . The solvent barrel 1 and the mixing barrel 6 are connected through a pipeline 12, and a solvent valve 2 is installed on the pipeline. When the viscosity value is greater than the set value, the cycle control PLC will open the solvent valve 2, and the solvent will enter the mixing barrel, and the viscosity will decrease; When the viscosity value is less than the set value, the circulation control PLC will close the solvent valve 2.

The stirring bucket is provided with the pneumatic stirring paddle, a raw glue injection port and the liquid level sensor, a solvent valve is mounted on a pipeline between the stirring bucket and a solvent bucket, the glue coating tank is provided with the liquid level sensor, a glue supplementing pipeline, a circulation pipeline and a residue glue collection pipeline are in connection with the glue coating tank and the stirring bucket, the glue supplementing pipeline is provided with the viscosity sensor and the pneumatic diaphragm pump, and the residue glue collection pipeline is provided with a ball valve. The glue liquid circulation system can implement automatic control of glue liquid viscosity and homogeneity in the honeycomb glue coating process, is high in efficiency, easy to operate, and low in device cost, and can meet the glue strip stability in the glue coating production process.

Description

technical field [0001] The invention belongs to the manufacturing technology of aramid paper honeycomb, and relates to a glue circulation system used in honeycomb gluing process. Background technique [0002] Aramid honeycomb core has a series of excellent properties such as: high specific strength, high specific modulus, good impact resistance, high fatigue resistance, excellent moisture and heat aging resistance, and corrosion resistance. The manufacturing process of the honeycomb core includes: glue coating, hot pressing, edge trimming, stretching, shaping, dipping, curing, and slice cutting. The gluing process is the first process in the production process of the honeycomb core material. The core strip glue is coated on the aramid paper. The viscosity of the core strip glue is the key factor for the amount of glue on the aramid paper in the gluing process. For the honeycomb laminated board The strength of the joint after curing has an important impact, and the quality o...
