Technical Field

[0002] Edge banding is a material used for edge treatment of furniture and wood products. It is mainly used to cover and protect the edge of the wooden board to prevent scratches, moisture and damage. Common edge banding is composed of PCV resin as the base material, calcium carbonate powder and various auxiliary materials. It has high plasticity and can maintain its original shape at room temperature. The installation of edge banding is usually pasted with hot melt glue or special glue, and sometimes an edge banding machine is used to improve efficiency and accuracy. It is necessary to ensure that the edges are flat during installation to avoid falling off or unevenness in the later stage.

One thickness measuring mechanism is a control group, and the other thickness measuring mechanism is a test group. The thickness change of the portion of the edge banding 212 that is ground by the grinding wheel 133 is judged by the difference in the height of the connecting column 307. The surface of the edge banding 212 is detected by three probes 304. The middle probe 304 is the control group, and the probes 304 on both sides are the test group.
