Due to the fact that the board material physical properties for the panel furniture are different, after the board is cut and sawed, the cut end face is uneven or sawn marks, waves and the like exist, if the edge is directly sealed, the edge sealing strips are difficult to attach, and the phenomenon of obvious glue lines or glue overflow can be caused.

Because the cutting edges of the cutting plate and the sawing tool are sharp, the quality of workpiece surface processing is better because the cutting edges of the cutting tool are sharp when the cutting plate and the sawing tool are just started to process, but after the cutting plate and the sawing tool are used for a period of time, the cutting edges are worn and passivated, and saw marks, waves and even edge breakage can occur on the cutting end surface of the workpiece. Therefore, before the edge of the plate is sealed, the cut end face needs to be trimmed to reduce the phenomena of wave and edge breakage.

Usually, a disc-type milling cutter is adopted on edge banding equipment to trim the cut end faces of the plates, and the trimming effect of the disc-type milling cutter of the existing edge banding machine on the cut end faces of the plates is poor. This is because, when processing panels such as shaving board, multiply wood, ecological plate, because there is vertically and horizontally staggered's wood fiber, the radial cutting of cutter, wood fiber is difficult to cut off, and some places can produce the arch, and when the bag sealer banding, the banding strip can not wrap the panel completely, and the laminating is insecure, must rubber coating during the banding in addition, and glue spills over the face easily, can produce obvious glue line after the banding, influences pleasing to the eye.
