Description

Technical Field

[0001] This utility model relates to the field of edge banding machine technology, and more specifically, to a plate thickness measuring device for a plate edge banding machine. Background Technology

[0002] A board edge banding machine is a specialized piece of equipment designed specifically for edge banding of boards. Its applications are wide-ranging, covering multiple industries including furniture manufacturing, cabinet production, and woodworking. This equipment is not limited to processing specific types of boards but is capable of edge banding various types of boards, including solid wood boards, various composite boards (such as MDF, particleboard, plywood, etc.), and other types of engineered wood products.

[0003] After the board is processed, its surface is not uniformly flat but has thickness variations, with some areas being thinner and others thicker. If the edge banding is trimmed to a fixed size, it will be difficult to ensure a precise fit between the edge banding and the board end, potentially causing the edge banding to exceed the board thickness or be cut to the board edge, resulting in damage or defects to the board. Therefore, to ensure the edge banding effect, the board thickness must be measured in real time and accurately to allow for subsequent fine trimming of the edge banding. Utility Model Content
