[0048] As a preferred implementation of the embodiment of the present invention, Figure 3 , Figure 7 As shown, a movable groove 17 is processed on one side of the lifting plate 13 close to the external plate 8, and the telescopic sliding connection unit is telescopically slidably installed in the movable groove 17, and the telescopic sliding connection unit includes:

[0053] Specifically, in this embodiment, the two sides of the two side columns 6 that are separated from each other are respectively processed with lifting grooves 11, and the lifting plate 13 can be slidably installed in the lifting grooves 11, and sliders 16 are correspondingly provided on both sides of the lifting plate 13. The side columns 6 are located on both sides of the lifting grooves 11 and are correspondingly processed with sliding grooves 12 that slidably cooperate with the sliders 16. The cooperation between the sliders 16 and the sliding grooves 12 is conducive to further improving the stability of the lifting and lowering movement of the lifting plate 13.

[0054] Furthermore, in some embodiments, the lifting drive unit includes a variable frequency motor 7 and a threaded rotating rod 15, the output end of the variable frequency motor 7 is fixedly connected to the threaded rotating rod 15, and is used to drive the threaded rotating rod 15 to rotate; the top of the lifting plate 13 is processed with an internal thread groove 14, and the other end of the threaded rotating rod 15 is threadedly matched with the internal thread groove 14. By adopting the spiral transmission mode of the threaded rotating rod and the internal thread groove, combined with the sliding guide of the slider in the slide groove 1, the smooth lifting and lowering of the lifting plate is achieved; at the same time, the design of the limit spring and the sleeve plate provides stable support and buffering for the movable column, further ensuring the stability of the lifting process. When adopting this lifting drive structure, when the spacing of the cutting knife is adjusted, the lifting plate 13 can also be locked in the height direction through the threaded matching of the threaded rotating rod 15 and the thread groove 14 to prevent shaking.

The active gear 34 is driven to rotate by the variable frequency motor 10, so that the active gear 34 and the tooth mouth 31 are meshed to push the slide plate 30 to drive the external plate 8 and the cutting knife to move together. The use of this adjustment structure realizes the precise electric adjustment of the cutting knife spacing. Compared with the existing manual or simple mechanical adjustment method, the accuracy and stability of the spacing adjustment are improved, and the errors caused by human factors are avoided, so that the cutting edge can be ensured to be flat, and the overall quality of the floor can be improved.

[0060] The embodiment of the present invention further provides a method for using any of the above-mentioned floor cutting devices, comprising:

[0061] Step 1: The distance adjustment driving unit drives the slide plate 30 to slide along the base 1, thereby driving the telescopic sliding connection unit to telescopically slide in the lifting plate 13, so that the external plate 8 moves in a direction close to or away from the side column 6, thereby adjusting the distance between the two cutting knives 9;

[0062] Specifically, the frequency conversion motor 10 is started, and the frequency conversion motor 10 drives the driving gear 34 to rotate in the gear groove 29. The driving gear 34 meshes with the teeth 31 on the left and right slides 30, driving the slide 30 to slide in the second slide groove 28. The movement of the slide 30 drives the movable column 18 to move in the movable groove 17 through the connecting plate 23. At the same time, the limiting slide bar 27 has a limiting effect in the limiting groove 25, thereby ensuring that the cutting knife 9 can move stably and accurately control the distance between the two cutting knives 9.

[0063] Step 2: The lifting plate 13 is driven to slide up and down along the side column 6 by the lifting driving unit. During the sliding process of the lifting plate 13 up and down, the movable plate 26 is driven to move up and down along the inside of the external plate 8 by the telescopic sliding connection unit, so as to adjust the height of the cutting knife 9;

[0064] Specifically, the variable frequency motor 7 is started, and the variable frequency motor 7 drives the threaded rotating rod 15 to rotate in the internal thread groove 14. The rotation of the threaded rotating rod 15 drives the lifting plate 13 to move up and down in the lifting groove 11. At the same time, the slider 16 slides in the slide groove 12 to ensure the smooth lifting and lowering of the lifting plate 13. The movement of the lifting plate 13 drives the moving plate 26 to lift and lower in the moving groove 24 in the external plate 8 through the movable column 18 and the connecting plate 23, thereby adjusting the height of the cutting knife 9.

[0065] Step 3. After the cutting knife 9 is adjusted to a suitable height and spacing, start the frequency conversion motor 7. The frequency conversion motor 7 drives the threaded rotating rod 15 to rotate in the internal thread groove 14. The rotation of the threaded rotating rod 15 drives the lifting plate 13 to move up and down in the lifting groove 11. At the same time, the slider 16 slides in the slide groove 12 to ensure the smooth lifting and lowering of the lifting plate 13. The movement of the lifting plate 13 drives the moving plate 26 to lift and lower in the moving groove 24 in the external plate 8 through the movable column 18 and the connecting plate 23, thereby adjusting the height of the cutting knife 9.

[0066] It is further preferred that during the cutting process, the dust generated during the cutting is led to the filter unit through the induced draft unit for filtration and then discharged. Specifically, the induced draft fan 38 is used to discharge the dust generated during the cutting through the dust inlet hood 39, the dust inlet pipe 40 and the dust exhaust pipe 41 to the interior of the filter box 37. The dust is purified and filtered through multiple layers of filter mesh in turn and is finally discharged through the outlet pipe 42. After the cutting is completed, all motors are turned off and the cutting operation is stopped.
