Description

Technical Field

[0001] The utility model relates to the technical field of wood processing, in particular to a numerical control machine tool for polishing wood boards. Background Art

[0002] During the processing of wooden boards, a large number of burrs will remain on the edges and surfaces of the boards after cutting.

[0027] A second sealing gasket 19 is provided at the discharge end of the second sealing cover 9, and the second sealing gasket 19 prevents wood chips from floating through the discharge port of the second sealing cover 9. A fan 16 is provided on the upper surface of the second sealing cover 9, and the air outlet end of the fan 16 is arranged in the second sealing cover 9. The fan 16 blows off the residual wood chips on the surface of the wooden board and collects the wood chips in cooperation with the dust collecting device.

[0028] The CNC machine tool for grinding wooden boards described in the embodiment is used to adjust the length between the support rod 11 and the fixed frame 1 according to the thickness of the wooden board, and adjust the angle of the first sealing cover 8 so that the distance between the grinding roller 10 and the upper surface of the conveyor 2 matches the thickness of the wooden board. After the adjustment is completed, the support rod 11 is fixed with the fixing bolt 12, and the wooden board is placed between the two upper limit plates 6. The turntable 7 is rotated to rotate the bidirectional lead screw 26, driving the two lower limit plates 25 to move toward or relative to each other, so that the two upper limit plates 6 move toward or relative to each other to adapt to the width of the wooden board. The two upper limit plates 6 are adjusted according to the width of the wooden board. The board width adjusts the position and direction of the wooden board entering the conveyor 2 to ensure that the surface of the wooden board is in full contact with the first grinding device and the second grinding device, and pushes the wooden board. The wooden board moves to the feeding end of the conveyor 2 through the limit assembly, and is moved by the conveyor 2 to the grinding roller 10. As the conveyor 2 moves, the motor 13 drives the grinding roller 10 to rotate to grind the upper surface of the wooden board. The conveyor 2 continues to move, and the cylinder 15 works. The two grinding blocks 21 abut against the edge of the wooden board. The wooden board moves while the grinding blocks 21 grind the edge of the wooden board. The wood chips generated during the grinding process are sucked into the dust box 17 through the dust suction pipe 20, and the fan 16 blows off the remaining wood chips on the surface of the wooden board, and cooperates with the dust collection device to collect the wood chips to prevent wood chips from polluting the workshop environment. After grinding, turn the wooden board over and rotate it 90 degrees. After grinding again, all six sides of the wooden board are polished.
