[0040] Since a certain amount of debris will be generated in the process of grinding the furniture profile, since the openings of the threaded rod protective cover 13 and the fixed rod protective cover 16 are both facing downward, and the fixed height of the furniture profile is higher than the lower ends of the threaded rod protective cover 13 and the fixed rod protective cover 16, the threaded rod 14, the furniture placement plate 15 and the fixed rod 17 can be protected in the process of grinding the furniture profile to prevent furniture debris from getting stuck in the connection between the furniture placement plate 15 and the threaded rod 14 and the fixed rod 17, causing the furniture placement plate 15 to get stuck and damaged, thereby affecting the service life of the threaded rod 14 and the furniture placement plate 15.

[0041] In the process of grinding the furniture profiles, some debris will fly. The two furniture debris baffles 24 block the debris, so that the debris falls into the furniture debris collection box 4 and is collected.

[0042] Furthermore, by the rotation of the grinding roller 11 around the second movable plate 7 and the stretching and compression of the spring 9 by the second movable plate 7, the grinding roller 11 can be closely attached to the curved surface of the furniture profile, and the second movable plate 7 is limited by the movable rod 8, so as to facilitate the grinding of the furniture profile and the adjustment and control of the grinding angle according to the curved surface of the furniture profile, thereby improving the practicability of the device and improving the grinding effect and efficiency of the device.

[0043] By using the threaded rod protective cover 13, the fixed rod protective cover 16 and the furniture debris baffle 24, it is convenient to protect the device during the grinding of furniture profiles.

[0045] Since some users will customize furniture profiles, during the customization process of furniture profiles, the surface of the furniture profile will have a certain curvature, and the grinding roller 11 will be squeezed by the furniture profile during the descent process, so that the grinding roller 11 drives the connecting bracket 10 to rotate around the second movable plate 7, so that the two grinding rollers 11 fit the surface of the furniture profile. At this time, the second drive motor 21 is started to drive the sprocket 22 to rotate, and the sprocket 22 drives the chain 23 and the grinding roller 11 to rotate, and the surface of the furniture profile is polished by the grinding roller 11.

[0046] During the process of grinding the furniture profile, the first drive motor 12 is started to drive the threaded rod 14 to rotate, and the threaded rod 14 drives the furniture placement plate 15 to slide on the inner walls of the threaded rod protective cover 13 and the fixed rod protective cover 16 and the surface of the fixed rod 17, so that the furniture placement plate 15 moves horizontally, and the furniture placement plate 15 drives the bracket 18, the electric telescopic rod 19 and the furniture profile fixing plate 20 to move, thereby driving the furniture profile to move. Since there is a certain curvature on the surface of the furniture profile, during the movement of the furniture profile, pressure will be continuously generated on the grinding roller 11, so that the grinding roller 11 moves up and down, and the grinding roller 11 drives the connecting bracket 10 to move, and the connecting bracket 10 drives the second movable plate 7 to move, and the second movable plate 7 drives the movable rod 8 to move, and stretches and compresses the spring 9.

[0047] Since a certain amount of debris will be generated in the process of grinding the furniture profile, since the openings of the threaded rod protective cover 13 and the fixed rod protective cover 16 are both facing downward, and the fixed height of the furniture profile is higher than the lower ends of the threaded rod protective cover 13 and the fixed rod protective cover 16, the threaded rod 14, the furniture placement plate 15 and the fixed rod 17 can be protected in the process of grinding the furniture profile to prevent furniture debris from getting stuck in the connection between the furniture placement plate 15 and the threaded rod 14 and the fixed rod 17, causing the furniture placement plate 15 to get stuck and damaged, thereby affecting the service life of the threaded rod 14 and the furniture placement plate 15.

[0048] In the process of grinding the furniture profiles, some debris will fly. The two furniture debris baffles 24 block the debris, so that the debris falls into the furniture debris collection box 4 and is collected.
