Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of honeycomb block production equipment, and more specifically, it relates to an internal and external pressure balancing device for uniformly impregnating honeycomb blocks with adhesive. Background Technology
[0002] Honeycomb blocks include paper honeycomb blocks: made from recycled paper or special paper through processes such as bonding and folding to form a hexagonal honeycomb structure, which is lightweight and has good sound insulation, heat insulation and cushioning properties; carbon fiber honeycomb blocks: made from carbon fiber as raw material through processes such as hot pressing, which has the characteristics of low density, high specific strength and high thermal stability; and metal honeycomb blocks: common types include aluminum honeycomb, which are prepared through processes such as hot pressing and stretching, and have high strength and good thermal conductivity. In the impregnation process of honeycomb blocks (such as paper and carbon fiber honeycomb), because their internal structure is closed or semi-closed, the adhesive is difficult to completely penetrate into the interior, resulting in uneven distribution of adhesive inside and outside, which affects the strength and stability of the product.
[0003] Based on the above, most traditional impregnation methods currently use atmospheric pressure or vacuum impregnation. Atmospheric pressure impregnation: the adhesive can only penetrate through the surface, and "dry areas" are easily formed inside, resulting in a low impregnation rate. Vacuum impregnation: although it can accelerate penetration, the air inside the honeycomb cannot be discharged in time, which easily produces air bubbles or incomplete filling of the adhesive. Existing pressure balancing devices: are mostly complex in structure and inconvenient to operate. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides an internal and external pressure balancing device for uniform impregnation of honeycomb blocks. This addresses the issues of conventional impregnation methods, which often employ atmospheric or vacuum impregnation. Atmospheric pressure impregnation allows the adhesive to penetrate only through the surface, easily creating "dry zones" inside and resulting in low impregnation rates. Vacuum impregnation, while accelerating penetration, prevents timely removal of air from the honeycomb interior, leading to air bubbles or incomplete adhesive filling. Existing pressure balancing devices are often complex in structure and inconvenient to operate.

[0011] The internal and external pressure balancing device for uniformly impregnating honeycomb blocks provided by this utility model has the following beneficial effects: This utility model achieves the following optimization effects by providing a glue-impregnated carrier frame, a load-bearing support frame, a closed carrier cover, and a load-bearing support: By using a double-support frame to carry both the honeycomb blocks and the adhesive, combined with the squeezing action of the pressure booster plate, the adhesive applies uniform pressure to both the inside and outside of the honeycomb blocks simultaneously. This effectively solves problems such as internal "dry zones" and residual air bubbles in traditional adhesive impregnation, ensuring that the adhesive penetrates the honeycomb pores in all directions. The sealing cover precisely connects to the support frame through a sealing groove, and the stable connection between the sealing cover and the lifting device ensures the sealing performance of the adhesive impregnation process and improves the overall structural rigidity of the device, preventing adhesive leakage or honeycomb block displacement during high-pressure adhesive impregnation. The hydraulic support drives the pressure booster plate to move efficiently, achieving rapid compression and pressure application of the adhesive. Compared with traditional adhesive impregnation methods, the impregnation time is shortened. The device can be adapted to honeycomb blocks of different specifications and materials by adjusting the size of the impregnation support frame and the hydraulic pressure parameters. The pressure guide pipe guides and carries the gas generated by the compression inside the impregnation support frame in real time, balancing the pressure distribution within the cavity and avoiding uneven adhesive distribution caused by local pressure concentration. This further ensures the stability and accuracy of the impregnation pressure, improving product strength and service reliability. Attached Figure Description
