Technical Field

[0001] This utility model belongs to the technical field of honeycomb panel production line, and relates to a continuous roller pressing composite drying oven for honeycomb panels. Background Technology

[0002] In the honeycomb panel production line, the face aluminum, honeycomb panel and bottom aluminum need to be laminated together. The lamination equipment usually adopts the track lamination machine. Under the heating and pressure environment, the pre-laminated face aluminum, honeycomb panel and bottom aluminum are laminated through the gap between the two layers of track.

[0003] Chinese utility model patent CN219727543U (publication date: 2023-09-22) discloses a continuous adhesive-coated honeycomb panel composite line, including a honeycomb panel conveyor line, a face aluminum conveyor line, a bottom aluminum conveyor line, and a composite line. The honeycomb panel conveyor line transports honeycomb panels, the face aluminum conveyor line transports face aluminum, and the bottom aluminum conveyor line transports bottom aluminum to the pre-composite unit of the composite line. The honeycomb panel conveyor line includes a honeycomb panel unloading table and a honeycomb panel stretching unit. The honeycomb panels on the unloading table are pulled through the honeycomb panel stretching unit. After stretching by the stretching unit, the aluminum enters the pre-composite unit. The aluminum surface conveying line includes an aluminum surface uncoiling machine and an aluminum surface coating machine. The aluminum surface on the aluminum surface uncoiling machine is pulled through the aluminum surface coating machine and then enters the pre-composite unit. The aluminum bottom conveying line includes an aluminum bottom uncoiling machine and an aluminum bottom coating machine. The aluminum bottom on the aluminum bottom uncoiling machine is pulled through the aluminum bottom coating machine and then enters the pre-composite unit. Downstream of the pre-composite unit, there are sequentially arranged a crawler composite unit, an air-cooling box, a protective film coating machine, a five-roll leveling machine, three sets of traction machines, and an automatic suction plate machine.

[0004] The aforementioned continuous adhesive-coated honeycomb panel composite line is a typical example of equipment that uses a tracked laminating machine for lamination. The drawbacks of this equipment are that the pressing pressure cannot be adjusted in stages, and the flatness after lamination is also unsatisfactory. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a continuous roller pressing composite oven for honeycomb panels, wherein the composite pressure can be adjusted independently in segments, and the honeycomb panels after continuous roller pressing also have better flatness.

[0006] To solve the above-mentioned technical problems, the objective of this utility model is achieved through the following technical solution:

[0007] A continuous roll forming composite oven for honeycomb panels includes a roll forming cavity enclosed by a top plate, a bottom plate, a front side plate, a rear side plate, a left side plate, and a right side plate. A hot air cavity enclosed by a partition is provided at the bottom of the roll forming cavity. The partition has several air outlets connecting the hot air cavity and the roll forming cavity. Several sets of composite pressure rollers are arranged inside the roll forming cavity along the conveying direction of the honeycomb panels. Each set of composite pressure rollers includes an upper pressure roller and a lower pressure roller. The upper pressure roller is raised and lowered by an independent adjusting device to adjust the gap between the pressure rollers. The front side plate has a strip-shaped inlet corresponding to the tangent position of the top of the lower pressure roller, and the rear side plate has a strip-shaped outlet corresponding to the tangent position of the top of the lower pressure roller. A fan is provided inside the hot air cavity. The fan's inlet is connected to a hot air device, and its outlet is connected to the air outlets on the partition.

[0008] In the aforementioned continuous roll forming composite oven for honeycomb panels, the partition is fixed to the bottom plate, and gaps are left between it and the left side plate, right side plate, front side plate, and rear side plate, forming maintenance space.

[0009] In the aforementioned continuous roll forming composite oven for honeycomb panels, the composite rollers are mounted on a column, the upper roller is slidably connected to a vertical track on the column, and the lower roller is fixedly connected to the column; furthermore, the upper roller is slidably connected to the vertical track via bearing seats at both ends, and the lower roller is fixedly connected to the column via bearing seats at both ends.

[0010] In the aforementioned continuous roll forming composite oven for honeycomb panels, the column is fixed on the base, and the base is also provided with a support stud for supporting the lower pressure roller bearing seat; preferably, the base is fixed on the crossbeams of the left and right side plates (along the conveying direction of the honeycomb panels).

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-5 :

[0026] A continuous roll forming composite oven for honeycomb panels includes a roll forming cavity 7 formed by a top plate 1, a bottom plate 2, a front side plate 3, a rear side plate 4, a left side plate 5, and a right side plate 6. A hot air cavity 9 formed by a partition plate 8 is provided at the bottom of the roll forming cavity 7. The partition plate 8 is provided with a plurality of air outlets connecting the hot air cavity 9 and the roll forming cavity 7. A plurality of composite pressure rollers are arranged in the roll forming cavity 7 along the conveying direction of the honeycomb panels. Each composite pressure roller includes an upper pressure roller 10 and a lower pressure roller 11. The upper pressure roller 10 is controlled to rise and fall by an independent adjusting device 12 to adjust the gap between the pressure rollers. The front side plate 3 has a strip-shaped inlet 13 corresponding to the tangent position of the top of the lower pressure roller 11. The rear side plate 4 has a strip-shaped outlet 14 corresponding to the tangent position of the top of the lower pressure roller 11. A fan is provided in the hot air cavity 9. The air inlet of the fan is connected to a hot air device, and the air outlet is connected to the air outlet on the partition plate 8.

[0027] The heating system in this embodiment is as follows: a heat sealing device (such as a gas-fired hot air blower) generates hot air, which, driven by a fan, enters the roller pressing chamber 7 through the air outlet on the partition 8 (generally located on the top partition 8) to meet the temperature requirements of the roller pressing composite within the roller pressing chamber 7. The roller pressing method in this embodiment is as follows: the pressure requirements for each stage of roller pressing are installed (different pressure requirements arise at each stage of roller pressing due to factors such as changes in material state), and the gap between each set of composite pressure rollers is independently adjusted by each adjusting device 12, thereby providing different roller pressing pressures at different roller pressing stages. When the honeycomb panel enters the roller pressing chamber 7 through the strip-shaped inlet 13, passes through each set of composite pressure rollers in sequence, and finally exits through the strip-shaped outlet 14, the honeycomb panel is continuously roller pressed and composited. In this embodiment, the top plate 1, bottom plate 2, front side plate 3, rear side plate 4, left side plate 5, and right side plate 6 are all made of heat-insulating material or have heat-insulating structures.

[0028] The aforementioned partition 8 is fixed on the base plate 2, and gaps are left between it and the left side plate 5, right side plate 6, front side plate 3 and rear side plate 4. These gaps form maintenance spaces. The maintenance spaces refer to the gaps that allow passage during maintenance. By setting up maintenance spaces, maintenance needs can be met, and the hot air cavity 9 can cover most of the area of ​​the roller pressing cavity 7.

[0029] In this embodiment, the specific structure of the composite pressure roller is as follows:

[0030] The aforementioned composite pressure roller is mounted on the column 15. The upper pressure roller 10 is slidably connected to the vertical track on the column 15, and the lower pressure roller 11 is fixedly connected to the column 15. Furthermore, the upper pressure roller 10 is slidably connected to the vertical track through bearing seats at both ends, and the lower pressure roller 11 is fixedly connected to the column 15 through bearing seats at both ends. When it is necessary to adjust the composite pressure roller, the adjusting device 12 drives the upper pressure roller 10 to move up and down.

[0031] Furthermore, the column 15 is fixed on the base 16, and the base 16 is also provided with a support stud 17 for supporting the bearing seat of the lower pressure roller 11; preferably, the base 16 is fixed on the crossbeam of the left side plate 5 and the right side plate 6 (along the conveying direction of the honeycomb plate). The above structure can further increase the structural strength and stability of the composite pressure roller.

[0032] Furthermore, the upper pressure roller 10 and the lower pressure roller 11 are each provided in pairs and are located on the front and rear sides of the column 15 respectively. Each set of composite pressure rollers is provided with a double roller pressing structure, which can improve the roller pressing efficiency and simplify its structure.

[0033] Furthermore, the bearing seats at both ends of the upper pressure roller 10 are respectively connected to adjusting seats 18 extending out of the roller pressing cavity 7. The adjusting seats 18 are connected to adjusting devices 12 that control their lifting and lowering. The adjusting devices 12 are located outside the left side plate 5 and the right side plate 6. When a pair of upper pressure rollers 10 are provided, two bearing seats can be connected to both sides of each adjusting seat 18 and drive a pair of upper pressure rollers 10 accordingly. By placing the adjusting devices 12 outside the roller pressing cavity 7, the adjusting devices 12 can be avoided from being affected by the high temperature of the roller pressing cavity 7.

[0034] The aforementioned adjustment device 12 adopts a conventional height adjustment structure in the art, preferably a pneumatic device, a hydraulic device, a servo motor (lead screw drive), or an electric push rod.

[0035] To improve the uniformity of heating, the heating mechanism in this embodiment is further configured as follows:

[0036] The hot air chamber 9 is provided with an air outlet chamber at its top. The air outlet of the fan is connected to the bottom of the air outlet chamber, and the air outlet hole is connected to the top of the air outlet chamber. The hot air driven by the fan first enters the air outlet chamber, and then, after being evenly pressurized in the air outlet chamber, it enters the roller pressing chamber 7 through the air outlet hole. Preferably, the air outlet chamber is provided with a flow equalization and air guiding structure. The flow equalization and air guiding structure can be a perforated flow equalization plate, a guide plate, a static pressure air box, etc. By setting the flow equalization and air guiding structure, the uniformity of heating can be further improved.

[0037] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
