The vacuum cleaner 1007 draws air into the dust collection box 1003 through the suction pipe 1006, and then generates suction through the dust hood 1001 and the corrugated pipe 1002, thereby sucking the waste and dust generated during cutting into the dust collection box 1003. The waste and dust are then filtered through the filter element 1004, and the filtered air is discharged through the exhaust port 1005, effectively reducing dust diffusion and achieving the effect of dust removal.

[0039] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 2 The lateral translation mechanism 9 includes two sets of one-way threaded rods 902, which are rotatably connected to the front and rear ends of the bottom of the inner cavity of the frame 11.

A slot 1202 is provided on the left side of the inner cavity of the filter element 1004 to engage with the insertion blocks 1201. The engagement of the insertion blocks 1201 and slots 1202 facilitates the periodic disassembly and cleaning of the coarse filter screen 10041 and the fine filter screen 10042. A one-way exhaust valve is provided at the top of the exhaust port 1005, ensuring that filtered air can only be discharged through the exhaust port 1005.

[0043] Please refer to the attached diagram in the instruction manual. Figure 1An electric telescopic rod 1 is installed on the top of the frame 11, and an installation ring 3 is installed at the bottom of the electric telescopic rod 1. A guide mechanism 2 is provided between the installation ring 3 and the frame 11. The guide mechanism 2 includes two sets of guide rods 202, which are respectively installed at both ends of the top of the installation ring 3. The tops of both sets of guide rods 202 extend out of the frame 11. The top of the frame 11 has guide holes 201 that match the guide rods 202. When the installation ring 3 is raised or lowered, it can drive the guide rods 202 to slide inside the guide holes 201, thereby making the installation ring 3 more stable when raised or lowered. A disassembly and assembly mechanism 13 is provided at the bottom of the installation ring 3, and a cutting blade 4 is installed at the bottom of the disassembly and assembly mechanism 13.

[0044] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 4 The disassembly and assembly mechanism 13 includes a groove 1301, which is installed at the bottom of the mounting ring 3. The top of the cutting blade 4 is equipped with a protrusion 1302 that engages with the groove 1301. A telescopic component 1305 is provided on the bottom of the mounting ring 3 near the groove 1301. A T-shaped limiting rod 1304 is connected to the telescopic component 1305 near the center of the mounting ring 3. A limiting groove 1303 is provided on the right side of the protrusion 1302 that engages with the T-shaped limiting rod 1304.

[0045] Please refer to the attached diagram in the instruction manual. Figure 4 The telescopic component 1305 includes a fixed plate 13052, which is installed at the bottom of the mounting ring 3. Movable rods 13053 are symmetrically installed at the upper and lower ends inside the fixed plate 13052. The left ends of both sets of movable rods 13053 are connected to the right ends of the T-shaped limiting rods 1304. Handles 13054 are installed on the right ends of both sets of movable rods 13053. Return springs 13051 are sleeved on the outer sides of both sets of movable rods 13053, and the return springs 13051 are located between the T-shaped limiting rods 1304 and the fixed plate 13052. When it is necessary to move the T-shaped limiting rods 1304, the handles 13054 are pulled to the right. The movement of the handles 13054, through the movement of the movable rods 13053, causes the T-shaped limiting rods 1304 to move.

[0046] Working principle: When in use, the product is first fed to the top of the workbench 7 by the feeding mechanism. The external power supply is connected to control the extension of the electric telescopic rod 1. The extension of the electric telescopic rod 1 drives the cutting blade 4 to move downward through the mounting ring 3 and the disassembly mechanism 13, thereby enabling the product to be cut.

[0047] During the cutting process, the vacuum fan 1007 is turned on. The vacuum fan 1007 draws air into the dust collection box 1003 through the suction pipe 1006, and then generates suction through the dust hood 1001 and the corrugated pipe 1002. This allows the waste and dust generated during cutting to be drawn into the dust collection box 1003. Large dust particles are filtered out through the coarse filter 10041, and smaller dust particles are filtered out through the fine filter 10042. The filtered air is then discharged through the exhaust port 1005, effectively reducing dust diffusion and achieving the effect of dust removal.

[0048] During the dust removal process, the servo motor 807 is turned on. When the servo motor 807 is working, it drives the second transmission pulley 805 to rotate through the second transmission shaft 806. The rotation of the second transmission pulley 805 drives the first transmission pulley 801 to rotate through the connecting belt 803. The rotation of the first transmission pulley 801 drives the first transmission shaft 802 to rotate, which in turn drives the two sets of one-way threaded rods 902 to rotate synchronously. Under the sliding cooperation of the slide groove 901 and the slider 904, the rotation of the one-way threaded rod 902 drives the threaded sleeve 903 to move left and right. This, in turn, drives the mounting plate 5 to move left and right through the support rod 905, thereby increasing the adsorption area of ​​the dust suction hood 1001 and making the dust removal effect of the cutting machine better.

[0049] When the cutting blade 4 wears out after prolonged use, the operator pulls the handle 13054 to the right. The handle 13054, through the movable rod 13053, moves the T-shaped limiting rod 1304 to the right, thereby separating the T-shaped limiting rod 1304 from the limiting groove 1303 and releasing the fixing effect of the T-shaped limiting rod 1304 on the protrusion 1302. At this time, the cutting blade 4 is pulled down, causing the protrusion 1302 to separate from the groove body 1301, making it easy to disassemble and replace the cutting blade 4.

[0050] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
