The wooden board is clamped by the clamping mechanism 5 to prevent the wooden board from moving during the cutting process, thereby improving the cutting quality of the wooden board. There is no contact between the clamping mechanism 5 and the upper surface of the workbench 1. Therefore, when the electric cylinder 4 pushes the wooden board to move to the right, the wooden board will not rub against the workbench 1, thereby reducing the wear of the wooden board. The clamping plate 502 is provided with two parallel plates 502, and the clamping plate 502 is provided in a "U" shape. The lower end of the first threaded rod 503 passes through the top of the clamping plate 502 and is connected to the pressing plate 504. The height of the pressing plate 504 can be adjusted by rotating the first threaded rod 503, which is convenient for clamping and fixing wooden boards of different thicknesses. Bottom support rods 6 are welded at the four corners of the bottom of the workbench 1.

[0027] The dust cover 7 is arranged at the top of the workbench 1, and a dust suction port 8 is arranged inside the dust cover 7. The top of the dust suction port 8 is connected with a pipe 9, and the top of the pipe 9 passes through the top of the dust cover 7 and is connected to a dust collecting outer box 10. An exhaust fan 11 is installed on the top of the dust collecting outer box 10. A filter plate 12 is arranged inside the dust collecting outer box 10, and a dust collecting inner box 14 is arranged parallel to the bottom of the filter plate 12. When the exhaust fan 11 is started, wood chips splashed during the cutting of the wooden board enter the dust suction port 8. Under the interception of the filter plate 12, the wood chips can be prevented from directly entering the exhaust fan 11, thereby extending the service life of the exhaust fan 11. The wood chips intercepted by the filter plate 12 fall into the dust collecting inner box 14, which is convenient for taking out and cleaning. Two limiting grooves 13 are fixed on the inner wall of the dust collecting outer box 10, and the filter plate 12 is installed inside the dust collecting outer box 10 through the limiting grooves 13. This setting makes it easy to disassemble and assemble the filter plate 12, and it is convenient to take out the filter plate 12 for cleaning.

[0028] The baffle 15 is arranged at the top of the workbench 1, and a slider 16 is integrated at the bottom of the baffle 15. Two slide grooves 17 are opened inside the upper surface of the workbench 1, and a double-headed screw 18 is rotatably connected inside the slide groove 17. A servo motor 19 is connected to the rear end of the double-headed screw 18. The double-headed screw 18 is provided with two parallel double-headed screws 18, and the rear ends of the two double-headed screws 18 are fixed with pulleys 20. The outer side of the pulley 20 is installed with a belt 21. Through the arrangement of the pulley 20 and the belt 21, the two double-headed screws can be rotated. 18 rotates synchronously to facilitate adjustment of the positions of the two baffles 15, the baffles 15 are provided with two parallel to each other, and the baffles 15 are slidably connected to the top of the workbench 1 through the slide groove 17 and the slider 16, and the side of the baffle 15 close to the clamping mechanism 5 is set as a step structure. This setting makes the distance between the two baffles 15 adjustable, which is convenient for matching with wooden boards of different sizes. The two sides of the wooden board are fitted with the two baffles 15 to move, so that the wooden board is not easy to skew when cutting, thereby improving the cutting quality. The baffle 15 with a step structure facilitates the stable placement of the wooden board.

[0029] Working principle: When in use, first start the servo motor 19 to drive the double-headed screw 18 to rotate. Through the setting of the pulley 20 and the belt 21, the two double-headed screws 18 rotate synchronously, thereby driving the slider 16 threadedly connected to the outer side of the double-headed screw 18 to move. According to the actual width of the wooden board, the distance between the two baffles 15 is adjusted so that the wooden board is just against the two baffles 15. The left end of the wooden board is inserted into the clamping plate 502, and the first threaded rod 503 is rotated clockwise to push the pressing plate 504 down until the pressing plate 504 is against the left end of the wooden board to fix the wooden board. The clamping machine is pushed by the electric cylinder 4. The structure 5 moves to the right, so that the wooden board approaches the cutting disk 3, and the rotating motor at the front end of the workbench 1 is started. The rotating motor is connected to the main shaft and drives the cutting disk 3 to rotate at high speed, so as to cut the wooden board. Since the two sides of the wooden board are respectively fitted with two baffles 15 to move, the wooden board is not easy to be skewed when being cut by the cutting disk 3, and the cutting quality is high. The exhaust fan 11 is started, and the wood chips generated by the cutting enter the dust collecting outer box 10 through the dust suction port 8 and the pipe 9, and are intercepted by the filter plate 12 inside the dust collecting outer box 10 and fall into the dust collecting inner box 14. When the device is used up, the dust collecting outer box 10 is opened, and the dust collecting inner box 14 is taken out for cleaning.
