[0028] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0029] like Figures 1-5 As shown, this application provides a chamfering and polishing device for flooring, including a processing table 1, a placement table 11 fixedly installed on the processing table 1, and a placement groove 12 opened on the placement table 11 for placing flooring, and a polishing assembly 2 installed on the processing table 1, the polishing assembly 2 including a top plate 21 installed on the processing table 1, the top plate 21 having two sets of support columns 22, the top plate 21 being fixedly connected to the top plate 21 through the support columns 22, and a reinforcing rod (not shown in the figure) connected between the two sets of support columns 22;

[0030] Four sets of guide columns 23 are fixedly installed on the top plate 21 near the placement platform 11, and guide plates 24 are movably sleeved between the four sets of guide columns 23. At the same time, a cylinder 215 is fixedly installed on the top plate 21. The telescopic end of the cylinder 215 is fixedly connected to the top of the guide plate 24. The guide plate 24 is adapted to move closer to or away from the placement platform 11 as the cylinder 215 moves.

[0031] Furthermore, a fixed frame 28 is installed on the guide plate 24 near the placement platform 11. The fixed frame 28 is concave, and a lead screw 29 is mounted on the fixed frame 28 with a bearing. A sliding seat 210 is threaded onto the lead screw 29. At the same time, two sets of limiting rods 211 are fixedly installed on the fixed frame 28. The two sets of limiting rods 211 are respectively located on both sides of the lead screw 29, and the sliding seat 210 is movably sleeved on the two sets of limiting rods 211. A first motor 212 is fixedly installed at one end of the fixed frame 28, and the output end of the first motor 212 is connected to one end of the lead screw 29.

[0032] The lead screw 29 is adapted to rotate with the output end of the first motor 212 to drive the sliding seat 210 to move along the straight direction of the limiting rod 211. A chamfering motor 213 is fixedly installed on the sliding seat 210, and a chamfering grinding head 214 is fixedly installed at the output end of the chamfering motor 213. The chamfering grinding head 214 is adapted to rotate with the output end of the chamfering motor 213.

[0033] A pressure plate 25 is movably sleeved between the two sets of vertically arranged guide columns 23 (see reference). Figure 3 Furthermore, a spring 26 is connected between the top of the pressure plate 25 and the guide plate 24. The spring 26 is sleeved on the guide post 23. The side of the pressure plate 25 has a pressing part 27. The contact area between the pressing part 27 and the floor is provided with an anti-slip pad (not shown in the figure). In the initial state, the pressure plate 25 is adapted to move away from the placement platform 11 under the action of the spring 26.

[0034] If chamfering and polishing of the floor is required, first place the floor on the placement groove 12, ensuring that the rear edge of the floor is the edge to be chamfered and polished. At this point, the two clamping parts 27 are positioned above the sides of the floor. By adjusting the position of the floor, the chamfering and polishing head 214 is positioned directly above the rear edge of the floor. Activate the cylinder 215, and the cylinder's extension end pushes the guide plate 24 downwards along the guide post 23. During the downward movement of the guide plate 24, it first brings the holding plate 25 closer to the floor. As the guide plate 24 continues to move downwards, the spring 26 is compressed. Under the spring pressure, the clamping parts 27 on the sides of the holding plate 25 use anti-slip pads to firmly press the sides of the floor, preventing the floor from shifting during processing.

[0035] Next, the first motor 212 is turned on, and its output drives the lead screw 29 to rotate. Since the sliding seat 210 is threadedly connected to the lead screw 29 and sleeved on the limiting rod 211, the rotation of the lead screw 29 causes the sliding seat 210 to move smoothly along the straight line of the limiting rod 211. At the same time, the chamfering motor 213 is started, and its output drives the chamfering grinding head 214 to rotate at high speed. The sliding seat 210 drives the rotating chamfering grinding head 214 to move along the rear side of the floor, cutting and grinding the floor to complete the chamfering and polishing operation. The top plate 21 is fixed to the processing table 1 by the support column 22, and two sets of reinforcing rods enhance the stability of the top plate 21, ensuring that the polishing assembly 2 operates stably during operation.

[0036] In this application, the clamping tightness of the floor can be improved by connecting fasteners between the clamping part 27 and the placement table 11;

[0037] To collect the dust generated during the floor beveling and polishing process, such as Figures 3-5 As shown, a dust collection assembly 3 is installed on the bottom surface of the reinforcing rod. The dust collection assembly 3 includes a guide rail 32 fixedly installed on the bottom surface of the reinforcing rod, and a slider 33 is slidably installed on the guide rail 32. A connecting rod 31 is connected between the slider 33 and the sliding seat 210. The connecting rod 31 makes the slider 33 move synchronously with the movement of the sliding seat 210.

[0038] A fixing rod 35 is fixedly installed on the slider 33. A dust cover 34 is fixedly installed on one end of the fixing rod 35. An internal gear ring 36 is fixedly installed on the side of the dust cover 34. The internal gear ring 36 is annular and has teeth distributed on its inner side. A rotating shaft 39 is installed on the central bearing of the dust cover 34. One end of the rotating shaft 39 passes through the dust cover 34. A limiting part 314 is fixedly installed on one end of the rotating shaft 39. The limiting part 314 fits against the dust cover 34. A main gear 38 is fixedly installed on the rotating shaft 39. Three sets of sun gears 37 mesh on the main gear 38. The three sets of sun gears 37 are arranged at 120-degree intervals along the center of the main gear 38.

[0039] Furthermore, the sun gear 37 meshes with the teeth of the internal gear ring 36, and the sun gear 37 has a central shaft, and a tripod 311 is movably sleeved on the rotating shaft 39. The tripod 311 has three sets of connecting ends (not shown in the figure), and the three sets of connecting ends are respectively fixedly connected to the central shafts of the three sets of sun gears 37.

[0040] Meanwhile, a mounting plate (not shown in the figure) is fixedly installed on the end of the rotating shaft 39 away from the dust cover 34. A second motor 315 is fixedly installed on the mounting plate. The second motor 315 is adapted to drive the rotating shaft 39 to rotate, so as to drive the main gear 38 to rotate. A connecting plate 310 is fixedly installed on the end of the central shaft away from the dust cover 34. A fan 312 is fixedly installed on one end of the connecting plate 310. A hose 313 is connected to one end of the fan 312. The hose 313 is adapted to collect and discharge the sucked waste.

[0041] When the floor chamfering and polishing operation begins, the sliding seat 210 moves linearly along the limiting rod 211 under the action of the first motor 212 driving the lead screw 29 to rotate. Since the slider 33 is connected to the sliding seat 210 through the connecting rod 31, the slider 33 will move synchronously with the sliding seat 210, thereby driving the fixed rod 35 and the dust cover 34 fixed on the slider 33 to move, so that the dust cover 34 always follows the chamfering polishing head 214 to maintain coverage of the dust-generating area.

[0042] The second motor 315 is started, which drives the rotating shaft 39 to rotate, and the main gear 38 on the rotating shaft 39 rotates accordingly. Since the main gear 38 meshes with three sets of sun gears 37 that are equidistant from each other at 120 degrees, and the sun gears 37 mesh with the internal gear ring 36, the rotation of the main gear 38 drives the internal gear ring 36 to rotate around the central axis of the dust cover 34 through the sun gears 37. Since the central axis of the sun gears 37 is fixedly connected to the three connecting ends of the tripod 311, and the tripod 311 is movably fitted onto the rotating shaft 39, the rotation of the sun gears 37 will drive the tripod 311 to perform circular motion around the rotating shaft 39.

[0043] A connecting plate 310 is fixed to the other end of the central axis of the sun gear 37, and a fan 312 is mounted on the connecting plate 310. When the tripod 311 drives the sun gear 37 to rotate around the axis 39, the fan 312 also rotates accordingly, forming an all-round, rotatable dust collection area inside the dust cover 34. When the fan 312 is working, it generates suction, which draws the dust generated by the chamfering grinder head 214 during the cutting and sanding of the floor into the dust cover 34, achieving effective dust collection, preventing dust from flying, protecting the working environment and equipment, and improving the quality of floor processing.

[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
