[0002] Honeycomb core panels, with their lightweight, high strength, sound insulation, and heat insulation properties, are widely used in aerospace, transportation, and architectural decoration. In practical applications, the waterproof performance of honeycomb core panels is crucial to their service life and overall performance, thus requiring the application of waterproof adhesive to their surface. However, existing methods for applying waterproof adhesive to honeycomb core panels have several problems, such as uneven spraying leading to poor waterproofing; lack of effective drying treatment resulting in long drying times and reduced production efficiency; and the inability to recycle excess adhesive, leading to material waste and increased production costs. Furthermore, traditional spraying devices have relatively independent functional modules, low integration, and large footprints, hindering large-scale production. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments. Unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. The features mentioned above or in the specific examples mentioned in this invention can be combined arbitrarily, and these specific embodiments are only used to illustrate this invention and are not intended to limit the scope of this invention.

[0021] Example 1

[0022] like Figure 1 and Figure 2 As shown, this utility model provides a waterproof adhesive spraying device for the surface of a honeycomb core panel, including a spraying unit 1, a drying unit 2, and a recycling unit 3. Each of the spraying unit 1, drying unit 2, and recycling unit 3 is equipped with a conveyor belt 4 below it. The adhesive dispensing mechanism of the spraying unit 1 is connected to the spraying mechanism. A drying hood 21 of the drying unit 2 is located behind the spraying mechanism. A recycling hopper 31 of the recycling unit 3 is located below both the drying hood 21 and the spraying mechanism. The recycling hopper 31 is connected to a recycling bin 34 via a recycling pipe 33.

[0023] The honeycomb core panel is driven by the conveyor belt 4 into the spraying unit 1 and the drying unit 2 in sequence. The recycling unit 3 simultaneously recycles the excess waterproof adhesive. Through the coordinated action of multiple units, the continuous operation of spraying, drying and recycling of waterproof adhesive for honeycomb core panels is realized.

[0024] The glue dispensing mechanism of the spraying unit 1 includes a glue dispensing tank 11 and a controller 16. The first glue inlet pipe 12 and the second glue inlet pipe 13 of the spraying mechanism are both connected to the glue dispensing tank 11, and the first glue inlet pipe 12 and the second glue inlet pipe 13 are both connected to a number of glue spraying head mechanisms.

[0025] The glue mixing mechanism of spraying unit 1 is connected to the spraying mechanism. Waterproof glue raw material is placed in the glue mixing tank 11 of the glue mixing mechanism and stirred evenly to obtain waterproof glue. The waterproof glue enters the first glue inlet pipe 12 and the second glue inlet pipe 13 of the spraying mechanism via a circulation pump. The glue supply of the circulation pump affects the glue spraying volume of the glue spraying head mechanism, and the glue spraying volume affects whether the honeycomb core board after exiting the drying hood 21 can complete the waterproof glue drying process. The controller 16 controls the stirring speed of the stirring motor 17 on the glue mixing tank 11 and the glue supply of the circulation pump to ensure the quality of the prepared waterproof glue and the uniformity of glue spraying on all parts of the honeycomb core board.

[0026] A number of heating rods 22 are evenly arranged on the upper part of the drying hood 21. Return air plates 24 are provided at both ends of the drying hood 21. A number of air inlet fans 23 are symmetrically arranged on the top of the drying hood 21. A conveyor belt 4 and a recycling trough 31 are arranged sequentially below the drying hood 21. The air inlet fans 23 are located above the heating rods 22 and work in conjunction with the heating rods 22 to blow hot air onto the honeycomb core panels on the conveyor belt 4 for drying. The hot air returns to the return air plates 24 on both sides of the drying hood 21 and guides the hot air circulation, making the temperature inside the drying hood 21 uniform. At the same time, it prevents the hot air from directly contacting the side walls of the drying hood 21 and dissipating into the environment, thus improving the heat energy utilization rate. While the drying hood 21 is drying, excess waterproof adhesive falls onto the recycling trough 31 via the conveyor belt 4 for recycling.

[0027] The height of the recycling trough 31 gradually decreases from both sides towards the center, and the height of the recycling trough 31 gradually decreases from back to front. The center of the bottom front side of the recycling trough 31 is connected to the recycling pipe 33. The recycling flow channel 32 below the recycling pipe 33 is inclined, and a recycling bucket 34 is provided below the lowest point of the recycling flow channel 32.

[0028] The multi-sloping flow guide and the rear-high-front-low design of the recycling hopper 31 allow for the complete recovery of excess waterproof adhesive under the combined effect of gravity and ventilation in the drying hood 21. The recovered waterproof adhesive can be directly reused. Excess waterproof adhesive in the recycling hopper 31 flows smoothly to the recycling pipe 33, then falls onto the recycling trough 32, and finally enters the recycling bin 34.

[0029] The adhesive spraying head mechanism includes an adhesive spraying hose 14 and an adjustable adhesive spraying head 15. One end of the adhesive spraying hose 14 is connected to either the first adhesive inlet pipe 12 or the second adhesive inlet pipe 13, and the other end of the adhesive spraying hose 14 is connected to the adjustable adhesive spraying head 15. The waterproof adhesive in the first adhesive inlet pipe 12 or the second adhesive inlet pipe 13 sequentially enters each adhesive spraying hose 14. By turning the adjustable adhesive spraying hose 14, the spraying areas of each adjustable adhesive spraying head 15 partially overlap to ensure no dead corners, ensuring that the waterproof adhesive is evenly sprayed on all parts of the honeycomb core panel, significantly improving the waterproof effect.

[0030] The conveyor belt 4 includes several conveyor rollers connected by a conveyor chain. The honeycomb core panel moves on the conveyor belt 4 under the drive of the conveyor rollers.

[0031] The side wall of the recycling hopper 31 is provided with several ventilation holes, and the drying hood 21 is connected to the recycling hopper 31. The ventilation holes on the side wall of the recycling hopper 31 are connected to the interior of the drying hood 21, which helps to remove moisture during the drying process, speeds up the drying process, and further improves production efficiency.

[0032] Example 2

[0033] A method for using a waterproof adhesive spraying device for honeycomb core panels, using the waterproof adhesive spraying device for honeycomb core panels in Example 1, includes the following steps:

[0034] S1. Place the honeycomb core panel on the conveyor belt 4 on one side of the spraying unit 1. The conveyor belt 4 drives the honeycomb core panel into the spraying unit 1.

[0035] S2. Adjust the angle of the spray nozzle mechanism so that the spraying range of each adjustable spray nozzle partially overlaps, evenly spraying waterproof adhesive onto all parts of the honeycomb core panel. This ensures that every part of the honeycomb core panel receives sufficient waterproofing treatment, improving the overall waterproof performance.

[0036] S3. Start the air intake fan 23 and heating rod 22 to preheat the inside of the drying hood 21. The conveyor belt 4 sends the honeycomb core board after spraying adhesive into the drying hood 21 to dry the waterproof adhesive on the honeycomb core board.

[0037] In step S3, the heating temperature of the heating rod 22, the air speed of the inlet fan 23, and the conveying speed of the conveyor belt 4 are controlled to ensure that the waterproof adhesive is dried after the honeycomb core panel leaves the drying hood 21. By precisely controlling the drying process, the waterproof adhesive can be dried quickly, while avoiding drying quality problems caused by excessively high or low temperatures or improper air speeds, thus improving product quality and production efficiency.

[0038] S4. Excess waterproof adhesive on the honeycomb core board drips from the conveyor belt 4 into the recycling hopper 31, and then enters the recycling bin 34 through the recycling pipe 33 and the recycling trough 32.

[0039] Therefore, the present invention provides a waterproof adhesive spraying device for the surface of a honeycomb core panel with the above-mentioned structure. By integrating the spraying unit, drying unit and recycling unit into a single design and providing a conveyor belt, it realizes continuous operation of waterproof adhesive spraying, drying and recycling of excess adhesive for the honeycomb core panel, and sprays adhesive on the honeycomb core panel without dead angles.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
