A first retaining ring 87 is fixedly connected to the outer wall of slider 85, and a clamping block 86 is fixedly connected to the first retaining ring 87. A lower rotating shaft 810 is snapped onto the outer wall of the cover 84, and a first bearing 89 is snapped onto the lower rotating shaft 810. A lower roller 811 is sleeved on the first bearing 89. The first bearing 89 reduces the frictional resistance between the lower roller 811 and the lower rotating shaft 810. A second retaining ring 88 is sleeved on the lower rotating shaft 810, and the second retaining ring 88 restricts the lower rotating shaft 810. The axial position of the first bearing 89 and the lower roller 811 is defined. A cover 84 is fixedly connected to a cover mesh 83 and a baffle 812. The cover mesh 83 has an installation port 81 and a ventilation port 82. A first exhaust pipe 1 is fixedly connected to the exhaust hood mechanism 8. A belt pad 9 and a belt pressure block 10 are fixedly connected to the first exhaust pipe 1. A second exhaust pipe 3 is fixedly connected to one outer wall of the first exhaust pipe 1. A third exhaust pipe 6 is fixedly connected to one outer wall of the second exhaust pipe 3. An air outlet 7 is provided on one outer wall of the third exhaust pipe 6. A flat belt 5 is fixedly connected to the first exhaust pipe 1, the second exhaust pipe 3, and the third exhaust pipe 6, and the flat belt 5 is sleeved on the upper roller 815 and the lower roller 811. A support member 4 is fixedly connected to one side of the outer wall of the first exhaust pipe 1, and an exhaust branch pipe 2 is fixedly connected to one side of the outer wall of the support member 4. A second bracket 14 is fixedly connected to one side of the outer wall of the exhaust hood mechanism 8, a first bracket 13 is fixedly connected to the second bracket 14, a fan box 12 is fixedly connected to the first bracket 13, and a blower fan 11 is fixedly connected inside the fan box 12.

[0018] Working Principle: When using this utility model, firstly, according to actual needs, assemble the three sheet metal parts—first exhaust pipe 1, second exhaust pipe 3, and third exhaust pipe 6—as required. Fix the second exhaust pipe 3 to one side of the outer wall of the first exhaust pipe 1, and then fix the third exhaust pipe 6 to one side of the outer wall of the second exhaust pipe 3, forming the main air duct. The support member 4 supports the exhaust branch pipe 2, which assists the main air duct in expanding the dust extraction coverage area. The air outlet 7 on one side of the outer wall of the third exhaust pipe 6 is responsible for discharging the collected dust. The flat belt 5 is fixed to the first exhaust pipe 1, the second exhaust pipe 3, and the third exhaust pipe 6 respectively. Simultaneously, the flat belt 5 is fitted onto the upper roller 815 and the lower roller 811. One end of the flat belt 5 is reinforced by the belt pad 9 and belt pressure block 10 fixed on the first exhaust pipe 1. At this time, the main air duct provides guidance for the flat belt 5 to prevent deviation and ensure a sealing effect during dust removal to avoid dust leakage. The outer wall of the cover 84 is clamped to the upper rotating shaft 816 and the lower rotating shaft 810. The first bearing 89 lowers the lower roller 811 and the lower rotating shaft 810. The frictional resistance between the upper roller 815 and the upper rotating shaft 816 is reduced by the second bearing 814. The second retaining ring 88 restricts the axial position of the first bearing 89 and the lower roller 811 on the lower rotating shaft 810, preventing these components from sliding axially along the lower rotating shaft 810. The third retaining ring 813 restricts the axial position of the second bearing 814, the slider 85, and the upper roller 815 on the upper rotating shaft 816, preventing these components from moving axially along the upper rotating shaft 816. The outer wall of the slider 85 is fixed with the first retaining ring 87, and the clamping block 86 clamps the first retaining ring. 87. Adjusting slider 85 can drive top clamping block 86 to adjust the position of exhaust hood mechanism 8. The ventilation port 82 of the cover 83 can suck in the dust generated by cutting. The installation port 81 facilitates the installation of cover 83 on cover 84. Baffle 812 can prevent dust from spreading to non-dust extraction areas. The first bracket 13 on the second bracket 14 fixes the fan box 12. The blower 11 fixed in the fan box 12 generates airflow after starting, which helps to blow the dust in the cutting area to the ventilation port 82 of cover 83. All components work together to achieve efficient and suitable dust removal operation.
