[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0020] See also Figures 1 to 5A handheld honeycomb sandwich panel edge banding tool includes a cloth roller 1, a pressing block handheld end 2, a cloth roller bracket 3, a pressing block connecting portion 4, a connecting plate 5, a flat glue block 6, a cloth roller sleeve 7, a cloth guide hole 8, a guard plate 9, a roller 10, a flat glue roller 11 and a flat glue groove 12, wherein the groove width of the flat glue groove 12 is consistent with the thickness of the surrounding honeycomb sandwich panel to be edge-banded, the height of the flat glue groove 12 is 3mm~6mm, the sum of the groove width of the flat glue groove 12 and the end surface thickness on both sides is greater than the width of the flat glue roller 11, and the width of the flat glue roller 11 is greater than the width of the flat glue roller 11. The thickness is greater than the thickness of the honeycomb sandwich panel to be edge-sealed around the periphery; the bottom of the flat rubber roller 11 after installation is on the same horizontal plane as the top plane of the flat rubber groove, and the two are separated by a certain distance. The cloth roller 1 consists of a middle cloth roller sleeve 7 and guard plates 9 on both sides. The cloth roller 1 is connected to the cloth roller bracket 3 through a roller 10. The roller 10 passes through the cloth roller sleeve 7 and the guard plate 9 in the middle of the cloth roller bracket 3. The roller 10 is detachable. The connection between the flat rubber roller 11 on the flat rubber block 6 is also a roller connection. The cloth roller 1 and the flat rubber roller 11 on the same side work together.

[0021] In this embodiment, the perimeter of the honeycomb sandwich panel is sealed in the following specific steps:

[0022] The structure of honeycomb sandwich panels is as follows Figure 4 As shown, the honeycomb sandwich panel consists of an adhesive film 13, a honeycomb core 14, upper and lower panels 15, and a peripheral sealant 16. Before edge sealing, a certain amount of honeycomb core must be removed around the honeycomb sandwich panel as required. When removing the area of ​​the honeycomb core 14, the upper and lower panels 15 are retained, and the adhesive film cured layer on the upper and lower panels 15 is removed with sandpaper. The upper and lower panels 15 must not be damaged during the removal process. After the removal is completed, all debris in the upper and lower panels 15 and the honeycomb core 14 is cleaned to ensure that the subsequent edge sealing quality meets the requirements.

[0023] Carry out edge banding around the honeycomb sandwich panel in a workshop that meets the requirements. Before edge banding, prepare the edge banding glue according to the ratio of the edge banding glue used, mix it evenly, and try to eliminate bubbles;

[0024] Then place the honeycomb sandwich panel with a certain amount of honeycomb core removed from the periphery on the workbench, and keep a certain height between the four sides of the honeycomb sandwich panel and the platform to facilitate the edge banding work. The edge banding glue is required to be 0.2mm~1.5mm higher than the edges of the upper and lower panels 15, so that the end face of the edge banding glue is approximately arc-shaped. Before the edge banding glue gels, use an edge banding tool to roll the edge banding glue around the honeycomb sandwich panel. Before rolling, it is necessary to install a peelable cloth with a certain thickness and width on the cloth roller 1. The peelable cloth is installed on the cloth roller sleeve 7, and guard plates 9 are installed on both sides of the cloth roller sleeve 7. Then, the cloth roller sleeve 7 and guard plates 9 are installed on the cloth roller bracket 3 through the roller 10. The cloth head of the peelable cloth is close to one side of the end face of the connecting plate 5, and the cloth head of the peelable cloth is passed through the connecting plate 5, passes through the cloth guide hole 8 on the flat glue block 6, then passes through the flat glue roller 11, and extends to the flat glue groove 12. The peelable cloth is required to be flat, without cross-twisted and folded areas, to ensure that the end surface of the edge sealing glue is flat after rolling. The excess edge sealing glue squeezed out during the rolling process needs to be cleaned in time. The peelable cloth must not be torn during cleaning to prevent the peelable cloth from lifting the edge sealing tape. After rolling, it is placed at room temperature for curing. After curing, the peelable cloth is torn off. The use of the peelable cloth can prevent the edge sealing glue from adhering to the flat glue roller 11 during the rolling process, and can also ensure that there are no holes on the end surface of the edge sealing glue after curing, thereby avoiding subsequent re-sealing due to the generation of holes, so that the designed edge sealing thickness and quality requirements can be met in one go.

[0025] Before and after each edge banding, the edge banding tools must be kept clean and intact to ensure the service life and edge banding quality of the edge banding tools.
