[0032] Working principle: First, plywood waste is fed into the square trough 2 through the feed hopper 3. Then, the first hydraulic cylinder 5 is activated, and its output end pushes the U-shaped push plate 4 into the square trough 2. The U-shaped push plate 4 pushes the waste into the square trough 2, preventing the waste from being placed on one side. After the waste is placed, the second hydraulic cylinder 6 is activated, and its output end pushes the extrusion plate 7 downward. The knife groove 8 at the bottom of the extrusion plate 7 contacts the waste, and together with the bottom inner wall of the square trough 2, the waste is initially extruded and fixed. Then, the second motor 23 is activated. The output of motor 23 drives screw 15 to rotate. The rotation of screw 15 causes moving plate 16 to move horizontally under the limiting action of limit rod 17, adjusting the position of cutting disc 19 so that the position of cutting disc 19 corresponds to the position of waste to be cut. Then, the first motor 21 is started. The output of the first motor 21 drives rotating rod 20 to rotate. Rotating rod 20 drives cutting disc 19 to rotate and cut. The debris generated by cutting falls through square hole 9 and is collected by inclined plate 12. After cutting is completed, the first hydraulic cylinder 5 drives U-shaped push plate 4 to move and push the cut waste out of square groove 2, completing one recycling cutting process.
