[0028] The following is combined with Figure 1-4 , the specific implementation methods of the utility model are further described in detail to make the technical solution of the utility model easier to understand and grasp.

[0029] The present application discloses a CNC wood cutting machine:

[0030] Reference Figure 1-4 A CNC cutting machine for wooden boards includes a machine platform 1, a frame 2, a three-axis drive assembly 3, a machine head 4 and a tool 5. The frame 2 is slidably connected to the machine platform 1, the three-axis drive assembly 3 is fixed on the frame 2, the machine head 4 is fixed on the three-axis drive assembly 3, and the output end of the machine head 4 is rotatably connected to the tool 5. It also includes a dust suction device 6, which includes a dust suction head 61, a dust suction pipe 62, a negative pressure component 63 and a dust collecting box 64. The dust suction head 61 is arranged on the machine head 4, and the dust suction head 61 is arranged toward the tool 5. One end of the dust suction pipe 62 is connected to the dust suction head 61, and the other end is connected to the dust collecting box 64. The negative pressure component 63 is used to make the dust collecting box 64 in a negative pressure environment. The application of the dust suction device 6 enables the debris and dust generated during the wood board cutting process to be immediately captured by the dust suction head 61 and pumped into the dust collection box 64 by the dust suction pipe 62, thereby reducing the flying of debris and dust in the working environment, reducing the health risks that may be brought about by workers working in a dusty environment for a long time, and reducing the production interruption time caused by equipment cleaning and maintenance.

[0031] Reference Figure 3-4, further comprising a limit plate 7, on which is provided an avoidance hole 71 for the output end of the machine head 4 to pass through, the limit plate 7 being sleeved on the outside of the output end of the machine head 4, and a drive source being fixed to the machine head 4 for driving the limit plate 7 to slide; the dust collector head 61 comprising a hollow column 613 and a dust extraction connector 612, the hollow column 613 being fixed on the side of the limit plate 7 facing the machine table 1, the tool 5 being arranged through the hollow column 613, and an annular dust suction port 611 being provided on the side of the hollow column 613 facing the machine table 1, the hollow column 613 being connected to the dust collection pipe 62 via the dust extraction connector 612. By placing the tool 5 in the annular dust suction port 611, the problem that the general dust collector head 61 can only extract dust and debris on one side is solved, and the annular dust suction port 611 wraps around the tool 5 without any dead angle, thereby improving the dust collection effect.

[0032] Reference Figure 3-4 , further comprising an annular brush 8, which is annular and vertically fixed to the side of the dust collector head 61 facing the machine 1. The annular dust collection port 611 is located within the annular brush 8. The vertical centerline of the annular brush 8 is collinear with the vertical centerline of the tool 5. The annular brush 8 abuts against the plate. The annular brush 8 is made of an elastic plastic material. The annular brush 8 acts as a wall outside the tool 5, blocking the dust and debris generated by the cutting tool 5 on the side of the annular brush 8 facing the tool 5, making it easier for the dust collection port located on this side to perform dust collection. Furthermore, due to the certain elasticity and toughness of the annular brush 8, it can provide effective protection for plates of different thicknesses, ensuring stability in the dust collection operation.

The telescopic rod of the electric cylinder 9 is vertically arranged, and the limit plate 7 is fixed to the telescopic rod of the electric cylinder 9. The electric cylinder 9 drives the limit plate 7 to move vertically outside the output end of the machine head 4, thereby driving the dust collector 61 and the annular brush 8 to move vertically outside the output end of the machine head 4, so as to facilitate the replacement of the tool 5 and the handling of plates of different thicknesses.

[0034] Reference Figure 1-2 The machine frame 2 further includes a tool magazine 10, which includes a tool holder 101 and a plurality of tool holders 102.

[0035] It also includes a tool changing assembly 20, which includes a cylinder 201, several slide rails 202 and a fixed plate 203. The fixed plate 203 is fixed to the end of the frame 2 away from the machine head 4, the cylinder 201 is fixed to the bottom of the fixed plate 203, and the telescopic rod of the cylinder 201 is fixed to the side of the tool clamp 101 away from the tool clamp 102. One end of the several slide rails 202 are respectively fixed on both sides of the bottom surface of the fixed plate 203, and the other end is fixed to the bottom surface of the machine table 1. The length direction of the slide rail 202 is set parallel to the length direction of the machine table 1, and the tool clamp table 101 is slidably connected to the slide rail 202. When the tool needs to be changed, there must be a vacant tool holder 102 on the tool holder table 101. The three-axis drive assembly 3 moves the machine head 4 to align with the vacant tool holder 102, and the cylinder 201 pushes the tool holder table 101 along the slide rail 202 toward the machine head 4, clamping the tool 5 on the machine head 4 on the vacant tool holder 102. Then the machine head 4 releases the tool 5, and the cylinder 201 pushes the tool holder table 101 to reset; the three-axis drive assembly 3 then moves the machine head 4 to align with the required tool 5, and the cylinder 201 pushes the tool holder table 101 to send the required tool 5 to the machine head 4, and the machine head 4 clamps the required tool 5; thereby automatically replacing the tool 5 and improving the processing efficiency.

[0036] Reference Figure 1 A collection trough 30 is fixed on one end of the machine table 1. After work is completed, the operator can lower the annular brush 8 through the electric cylinder 9, and then use the three-axis drive assembly 3 to move the larger debris on the machine table 1 that has not been sucked away by the dust collection device 6 into the collection trough 30.
