The driving chamber is fixedly connected to one end of the protective shell, one end of the rotating shaft can be rotatably connected to the inner wall of the protective shell, the other end of the rotating shaft passes through the protective shell and extends into the driving chamber, the rotating shaft is symmetrically arranged, the transmission mechanism is arranged in the driving chamber and connected to the rotating shaft, the removal roller is fixedly connected to the outer wall of the rotating shaft, and the limiting sliding assembly is fixedly connected to the bottom opening of the protective shell for fitting the side walls of boards of different thicknesses.

[0005] Furthermore, the transmission mechanism includes a rotating motor, a driving wheel and a driven wheel. The rotating motor is installed at one end of the driving cavity away from the protective shell. The driving wheel is fixedly connected to the output end of the rotating motor. The driving wheel is located in the driving cavity. The driven wheel is fixedly connected to the end surface of the rotating shaft. The driven wheels are symmetrically arranged on both sides of the driving wheel, and the driven wheel is meshed with the driving wheel.

[0006] Furthermore, the limiting sliding assembly includes a support rod and an adjusting stud, the support rod is arranged at the bottom opening of the protective shell, the support rods are symmetrically arranged in pairs, one end of the adjusting stud passes through the side wall of the support rod and is threadedly connected to the support rod, and the adjusting stud is radially distributed perpendicular to the rotating shaft.

[0007] Preferably, the removal roller is arranged in a truncated cone shape.

[0008] Furthermore, a handle is provided on a side of the protective shell away from the opening.

[0009] After adopting the above structure, the beneficial effects of the utility model are as follows: for the edge and corner cutting of the plate, the edges and corners on both sides of the plate are grinded and removed through the symmetrical rotation of the removal rollers, so that the cutting depth can be quickly fed, and under the limiting action of the limiting sliding component, the device is pushed along the edge of the plate to move, and the edges and corners on both sides of the plate are grinded and removed at the same time. The arc-shaped bends of the edges and corners of the plate can also be grinded and removed, thereby improving the cutting efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] like Figure 1-4 As shown, a device for cutting corners of building boards comprises a protective shell 1, which is a hollow cavity with an opening at the bottom, and also comprises a removal roller 2, a driving cavity 3, a transmission mechanism 4, a limit sliding assembly 5 and a rotating shaft 12. The driving cavity 3 is fixedly connected to one end of the protective shell 1, one end of the rotating shaft 12 is rotatably connected to the inner wall of the protective shell 1, and the other end of the rotating shaft 12 passes through the protective shell 1 and extends into the driving cavity 3. The rotating shaft 12 is symmetrically arranged, the transmission mechanism 4 is arranged in the driving cavity 3 and is connected to the rotating shaft 12, the removal roller 2 is fixedly connected to the outer wall of the rotating shaft 12, and the limit sliding assembly 5 is fixedly connected to the bottom opening of the protective shell 1 for fitting the side walls of boards of different thicknesses.

[0017] like Figure 3 and Figure 4As shown, in order to make the symmetrical removal roller 2 rotate quickly and realize the removal of the edges and corners of the plate, the transmission mechanism 4 includes a rotating motor 6, a driving wheel 7 and a driven wheel 8. The rotating motor 6 is installed at the end of the driving cavity 3 away from the protective shell 1, and the driving wheel 7 is fixedly connected to the output end of the rotating motor 6. The driving wheel 7 is located in the driving cavity 3, and the driven wheel 8 is fixedly connected to the end surface of the rotating shaft 12. The driven wheels 8 are symmetrically arranged on both sides of the driving wheel 7. The driven wheel 8 is meshed with the driving wheel 7. The rotating motor 6 drives the driving wheel 7 to rotate quickly. Through the meshing of the driven wheels 8 on both sides, the removal roller 2 rotates quickly and contacts the edges and corners of the plate to realize the removal of the edges and corners of the plate. The removal roller 2 is arranged in a truncated cone shape, which is convenient for the side wall of the removal roller 2 to gradually contact the edges and corners of the table.

[0018] like Figure 2 and Figure 3 As shown, in order to enable the device to remain stable during movement, the limiting sliding assembly 5 includes a support rod 9 and an adjusting stud 10. The support rod 9 is arranged at the bottom opening of the protective shell 1, and the support rods 9 are symmetrically arranged in pairs. One end of the adjusting stud 10 passes through the side wall of the support rod 9 and is threadedly connected to the support rod 9. The adjusting stud 10 is radially distributed and perpendicular to the rotating shaft 12. The end face of the adjusting stud 10 is rotated to adjust the end face. The end face of the adjusting stud 10 is symmetrically limited at the upper and lower sides of the plate, so that the device can be pushed along the edge of the plate, thereby increasing the working stability of the device.

[0019] A handle 11 is provided on one side of the protective shell 1 away from the opening, which is used to lift the device to move and facilitate holding and fixing the pressing device.

[0020] During specific use, the operator holds the handle 11, points the smaller diameter end of the symmetrical removal roller 2 forward, and rotates the adjusting stud 10 so that the end faces of the adjusting stud 10 are close to the upper and lower sides of the plate, and can keep the device from sliding after contacting the corners, drives the rotating motor 6 to rotate, and the driving wheel 7 drives the driven wheels 8 on both sides to rotate, so that the rotating shaft 12 and the removal roller 2 rotate rapidly, pushing the protective shell 1 to move, so that the symmetrical corners of the plate gradually contact the removal roller 2, and the corners are removed during the movement of the removal roller 2.

[0021] Although the embodiments of the utility model have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the utility model, and the scope of the utility model is defined by the attached claims and their equivalents.
