At present, the honeycomb hollow composite board has wide application prospects in the fields of furniture, wood doors and the like due to the advantages of light weight, material saving and the like, but a core layer of the honeycomb hollow composite board is poor in bearing capacity due to a thin-wall large-hole structure and cannot be subjected to direct edge sealing, and a mode of embedding solid wood strips is usually adopted for reinforcing, connecting other plates and providing support for the edge sealing, but the process is complex, the manual frame embedding efficiency is low, the comprehensive cost is high, and the application range and the scene of the plate are limited. The edge sealing and surface covering integrated V-shaped groove forming method is characterized in that a surface covering material is reserved by cutting a base material, so that a light core material is wrapped in a bending mode, and edge sealing and surface covering of each surface of a furniture plate are achieved. The edge-sealing and surface-covering integrated V-shaped groove forming method integrates edge sealing and surface covering of the plate, has small joint, attractive edge sealing, difficult warping, material saving, simple process and contribution to industrial production.

The composite base material of the edge-sealing and surface-covering integrated V-shaped groove at least comprises a base material and a veneer material layer which are glued together. And if the section graph of the plate is an N-sided polygon, the cutting track is that the N-sided polygon is unfolded into (N +2) surfaces, a cutting V-shaped groove is arranged on the bevel edge of the composite base material, the cutting depth is the thickness of the base material, the veneering material layer is reserved, and the angle of the V-shaped groove cut by the bevel edge is 88-100 degrees. The outer contour of the same plate is determined to be dynamic and various in the expansion form, and the groove position dynamically changes along with the outer contour. The cutting track of the groove is the outer contour of the mapping graph, the cutting edge of the composite base material is formed, the cutting depth is the thickness of the composite base material, the mapped redundant part is cut off, the obtuse angle of the groove cut off of the cutting edge is 130-137 degrees, the composite base material is folded, and the groove are bonded smoothly.

The section shape of the light core material can be a polygonal figure such as a triangle, a quadrangle, a pentagon, a hexagon or an octagon, and the light core material is various prism polyhedrons.
The technology also develops a forming device for processing the V-shaped groove. The forming device is provided with a clamp for fixing the composite base material, and four corners of the composite base material are fixed. When the base material is a paper-based material, the base material is cut by a blade, the blade is fixed on the base by a pressure lever, the pressure lever is provided with a chute with the angle of 25-45 degrees and is used for determining the inclination angle of the blade during cutting, the cutting mode of the blade is single-knife back and forth cutting or double-knife one-time cutting, and the base is fixed on the device by a screw. The blade runs on the bevel edge to cut the V-shaped groove, and the angle (A) of the V-shaped groove is 88-100 degrees. The blade operates to cut the cut edge into a groove, and the cut obtuse angle (Z) of the groove is 130-137 degrees; when the substrate is a wood-based material, the apparatus used is a milling machine. The angle (A) of the V-shaped groove after milling by the milling cutter is between 88 and 100 degrees.
