The utility model discloses a
batten excess material
finger joint utilization device after fixed-length
cutting processing, and belongs to the technical field of
wood machining. Waste materials with different lengths can be
cut into tenon shapes and subjected to
finger joint, operation is convenient and fast,
automation is high, and the
utilization rate of wood is increased. The
finger joint device is fixedly connected to the bottom of the sawing
machine and is arranged below the excess material opening; a channel opening is formed in the middle of the upper end of the rack and communicated with the excess material opening in a
butt joint mode, the tenon milling mechanism is arranged below the channel opening, and the pressing mechanism and the feeding mechanism are arranged on the front side and the rear side of the discharging end of the tenon milling mechanism respectively. By arranging the sawing
machine and the finger joint device, double surfaces of
batten excess materials with different lengths are
cut into tenons and finger-jointed into long wood, so that the wood
utilization rate is improved, and the recycling and crushing labor cost is saved. According to the utility model, the tenon cutter axially moves through the fine adjustment
assembly, so that tenons which are opened by mistake can be fully automatically
cut by using one cutter, the stability and the strength of wood finger joint are ensured, and the reliability of an automatic finger joint process is obviously optimized.
