Description

Technical Field

[0001] This utility model belongs to the field of adhesive coating machine technology, and in particular relates to an adhesive coating device for aluminum honeycomb core. Background Technology

[0002] Aluminum honeycomb core is made of multiple layers of aluminum foil bonded, stacked, and then stretched into a regular hexagonal honeycomb core. The densely packed, interlocking honeycombs act like many small I-beams, distributing the pressure from the panel direction and ensuring uniform stress distribution. This guarantees a high degree of flatness even when the panel covers a large area. Simultaneously, the hollow honeycomb structure significantly reduces the thermal expansion of the panel. Due to its advantages such as light weight, high strength, good rigidity, corrosion resistance, aging resistance, and good sound and heat insulation, it is widely used in decorative materials, home appliances, lighting, transportation, and furniture industries. Existing adhesive application equipment typically uses rollers to apply adhesive to the surface of the aluminum sheet.

[0003] The manufacturing equipment for aluminum honeycomb cores varies greatly, with many producing irregularly shaped cores that are not visible from the inside. This seriously hinders the development of the aluminum honeycomb core industry. Furthermore, the adhesive coating machines for aluminum honeycomb cores have many defects, such as the inability to control the adhesive spacing. While existing adhesive coating devices can coat aluminum plates, they use rollers for coating, which cannot control or adjust the adhesive thickness, severely impacting product quality.

An adjustable-space glue coating mechanism is provided in the middle between the two side plates. The glue coating mechanism consists of an upper glue coating mechanism and a lower glue coating mechanism. Two vertically distributed scrapers with adjustable spacing are provided on one side of the glue coating mechanism. The upper glue coating mechanism includes multiple connecting rod assemblies connected end-to-end, and a connecting seat is provided between each pair of adjacent connecting rod assemblies.

The structure of the lower adhesive coating mechanism is the same as that of the upper adhesive coating mechanism. The connecting rod assembly 8 consists of four connecting rods 16, which are connected end to end by a rotating shaft and form a parallelogram structure. Both ends of the connecting seat 9 are rotatably connected to the connecting rod assembly 8 via a rotating shaft. A vertical plate 6 is provided in the middle of the upper surface of each of the two side plates 1. A bidirectional lead screw 7 is rotatably connected between the two vertical plates 6 via a bearing.
