Description

Technical Field

[0002] Honeycomb panels are lightweight, high-strength composite materials composed of two thin layers and a honeycomb core, widely used in construction, aerospace, transportation, and other fields. The manufacturing process includes preparing the panel and core materials, fabricating the honeycomb structure, bonding the panels and core using adhesives, hot-pressing and curing, cutting and shaping, and finally quality inspection. Honeycomb panels are widely used in applications requiring weight reduction while maintaining high structural stability due to their excellent strength, lightweight properties, and good compressive strength.

[0003] A search revealed an existing patent (publication number: CN207789949U) that discloses a gluing device for manufacturing honeycomb panels. This invention avoids the waste of molten glue by applying glue to the part of the honeycomb core with the honeycomb holes removed, and the automated gluing process avoids the inconvenience of manual gluing, which is laborious and time-consuming.

[0004] However, the above method, due to excessive adhesive application, may generate a significant amount of volatile organic compounds (VOCs) during the application process. These VOCs not only pollute the environment and affect air quality during volatilization, but also pose potential health hazards to operators. Prolonged exposure to VOCs may cause respiratory discomfort, dizziness, nausea, and even increase the risk of some chronic diseases. Furthermore, VOC emissions exacerbate air pollution, especially in enclosed spaces, easily leading to a decline in indoor air quality and affecting work efficiency and health. Utility Model Content

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] Reference Figures 1-2 This is the first embodiment of the present invention, which provides a manufacturing equipment for low-VOC volatile honeycomb panels.

[0030] The device comprises two housings 1, each housing 1 containing two symmetrically distributed, oppositely positioned hydraulic push rods 2. This double-housing design enhances the overall rigidity of the equipment. The symmetrical hydraulic push rods provide balanced thrust, ensuring uniform stress during the pressing process and preventing unilateral deformation. The two housings 1 are fixedly connected by four symmetrically distributed connecting support columns 3. A clamping plate assembly 4 is located on one opposite side of the two housings 1. Glue application assemblies 5 are located on the inner side of the connecting support columns 3 near the two ends of the clamping plate assembly 4. The modular layout optimizes space utilization, and the glue application and stretching processes work in tandem, enabling a continuous process of applying glue, stretching, and then pressing. A stretching assembly 6 is located at the center of the inner side of the connecting support columns 3.

[0031] The glue application assembly 5 includes two square rods 501, which are symmetrically fixed to the connecting support column 3. The two square rods 501 are provided with glue storage boxes 502 that slide along their length direction on their opposite inner sides. The glue storage boxes 502 are fixed with connecting rods 503 at both ends. One end of the connecting rod 503 extends to the inner side of the square rod 501 and is equipped with an electric pulley 504. The bottom end of the glue storage box 502 is fixed with a scraper 505. Multiple glue application nozzles 506 are provided at equal intervals on one side of the scraper 505.

[0032] Square rods and grooves ensure the linear motion accuracy of the glue storage box; the triangular scraper gap design controls the glue layer thickness and avoids excessive glue application; equidistant glue nozzles achieve uniform glue distribution.

[0033] The scraper 505 is triangular in shape, and there is a gap between the scraper 505 and the plate body.

[0034] The square rod 501 has a groove 507 inside. The inner side of the groove 507 is in close contact with the surface of the electric pulley 504, and the electric pulley 504 rolls inside the groove 507.

[0035] Example 2

[0036] Reference Figures 1-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the tensioning component 6 includes a housing 601, which is fixedly connected to the center of the inner side of the connecting support column 3. The housing 601 is provided with a bidirectional lead screw 602 inside. The surface of the bidirectional lead screw 602 is symmetrically provided with two sliders 603 that are threadedly connected to it. A connecting block 604 is fixed on one side of the slider 603. A protrusion 605 is fixed above one end of the connecting block 604. The bidirectional lead screw 602 is driven by a drive motor 606. The surface of the drive motor 606 is provided with a protective shell 607.

[0037] The bidirectional lead screw enables synchronous reverse motion, ensuring the honeycomb core is stretched in the center; the rectangular groove limits the slider to prevent rotation and improves stretching stability; the protrusion is inserted into the honeycomb core to precisely align the plate length.

[0038] The outer casing 601 has a circular groove 608 inside. The cross-sectional shape of the circular groove 608 is the same as that of the slider 603. The slider 603 is slidably connected to the inner side of the circular groove 608.

[0039] A rectangular groove 609 is provided on the side of the circular groove 608 near the connecting block 604. The connecting block 604 is slidably connected to the inner side of the rectangular groove 609. The connecting block 604 forms a limiting structure for the slider 603 through the rectangular groove 609.

[0040] The clamping plate assembly 4 includes a box body 401, which is fixed to one side of the housing 1. Two fixing rods 402 are symmetrically fixed inside the box body 401. Two L-shaped clamping blocks 403 that slide in opposite directions along their length are symmetrically provided on the surface of the fixing rods 402. The L-shaped clamping blocks 403 are fixedly connected to the inner wall of the box body 401 by a return spring 404. The return spring 404 is sleeved on the surface of the fixing rods 402. A circular hole 405 is provided on one side of the box body 401 at the position corresponding to the hydraulic push rod 2 for the output end of the hydraulic push rod 2 to pass through.

[0041] The reset spring automatically adjusts the position of the L-shaped clamping block to adapt to plates of different thicknesses; the square groove restricts the movement direction of the L-shaped clamping block to ensure that the clamping does not deviate; the circular hole avoids interference with the movement of the hydraulic push rod.

[0042] A square groove 406 is provided at the corresponding position of the box body 401 and the L-shaped clamp 403, and the L-shaped clamp 403 is slidably connected to the inner side of the square groove 406.

[0043] Based on embodiments 1-2, the working principle of this utility model is as follows: The user places the plate to be bonded to the honeycomb core into the inner side of the clamping assembly 4. The clamping assembly 4 adaptively clamps the plate. The stretching assembly 6 stretches the honeycomb core to be bonded to the same length as the plate. The gluing assembly 5 applies glue to the surface of the plate fixed on the clamping assembly 4. Then, the hydraulic push rod 2 inside the housing 1 pushes the plate inside the clamping assembly 4 to press the honeycomb core together.

[0044] By inserting the plate into the inside of the box 401, an L-shaped clamping block 403 is pushed to slide on the surface of the fixing rod 402, so that the plate is embedded in the inside of the box 401. Then, by the relative action of two return springs 404, the L-shaped clamping block 403 drives the plate to be centered and fixed.

[0045] The drive motor 606 drives the bidirectional lead screw 602 inside the housing 601 to rotate, thereby causing the two sliders 603 to move relative to or repel each other. The core of the honeycomb core is inserted into the protrusion 605. The slider 603 drives the protrusion 605 to slide inside the circular groove 608 synchronously through the connecting block 604, so that the honeycomb core and the plate are of the same length and aligned in the center.

[0046] The electric pulley 504 drives the glue storage box 502 to move horizontally via the connecting rod 503. The scraper 505 on one side of the glue storage box 502 can scrape and spread the glue. The glue spray nozzle 506 sprays the glue. The chute 507 can keep the linear movement of the electric pulley 504 stable.

[0047] Finally, the plate is pressed onto the honeycomb core through the circular hole 405 at the output end of the hydraulic push rod 2.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this 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 be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
