[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-6 A decoration putty grinding device in this embodiment includes a shell 1, a mounting seat 2 is fixed in the shell 1, a grinding disc 3 is provided at the bottom of the mounting seat 2, and a driving mechanism 4 for driving the grinding disc 3 to slide back and forth is provided on the mounting seat 2. The grinding disc 3 is placed close to the wall, and the driving mechanism 4 is used to drive the grinding disc 3 to slide back and forth to realize automatic grinding.

[0024] The driving mechanism 4 can convert the rotational motion of the driving source into the horizontal linear motion of the grinding disc 3. Figure 2-3 As shown, the driving mechanism 4 includes a driving motor 401 fixed on the mounting base 2, the output shaft of the driving motor 401 is fixed with an eccentric wheel 402, the eccentric part of the eccentric wheel 402 is hinged with a connecting rod 403, the other end of the connecting rod 403 is provided with a movable block 404 through a rotating shaft, a positioning rod 405 fixed on the mounting base 2 passes through the movable block 404, the rear side surface of the movable block 404 is provided with a pushing arm 406 through a rotating shaft, and the other end of the pushing arm 406 is provided on the top surface of the grinding disc 3 through a rotating shaft.

[0025] The output shaft of the driving motor 401 drives the eccentric wheel 402 to rotate. Under the linkage action of the connecting rod 403, the movable block 404 can move linearly up and down under the guidance of the positioning rod 405. Under the linkage action of the pushing arm 406, the grinding disc 3 can slide back and forth at the bottom of the mounting seat 2.

[0026] In order to ensure the stability of the grinding disc 3 when sliding back and forth, Figure 4-5 As shown, the top surface of the grinding disc 3 is recessed downward to form a T-slot 31, and rectangular through slots 21 cooperating with the grinding disc 3 are provided on the left and right sides of the mounting seat 2. Under the limiting effect of the T-slot 31 and the rectangular through slot 21, the grinding disc 3 slides back and forth on the bottom surface of the mounting seat 2 without falling off, and a stepped opening 22 is also provided at the rear end of the mounting seat 2 for the hinged seat connecting the grinding disc 3 and the push arm 406 to slide back and forth in the stepped opening 22.

[0027] Since the connection between the grinding disc 3 and the pushing arm 406 is connected by bolts and nuts, the bolts and nuts limit the end of the pushing arm 406 on the grinding disc 3, and the end of the pushing arm 406 can rotate freely on the surface of the bolt, so by unscrewing the bolt, the grinding disc 3 can be removed from the bottom of the mounting base 2, which is convenient for maintenance. A mounting groove 32 connected to the T-slot 31 is provided on the side of the grinding disc 3, and a positioning groove 23 connected to the step opening 22 is provided on the mounting base 2. When the grinding disc 3 slides to the mounting groove 32 and corresponds to the positioning groove 23 on the mounting base 2, the hinge shaft can be unscrewed, and the grinding disc 3 can be slid out of the mounting base 2, and then a new grinding disc 3 can be installed.

[0028] As a preferred embodiment, the grinding device can also be used for dual purposes. First, the grinding disc 3 is removed, and then the saw blade is installed on the device, so that the saw blade can be cut, which is more flexible when used. Figure 6 As shown, a knife groove 24 is provided on the front side of the movable block 404, the front side of the mounting seat 2 is recessed inward, and a positioning wheel 25 is provided at the recessed part of the front side of the mounting seat 2 through rotation of a rotating shaft. The saw blade not shown in the figure is installed to the knife groove 24 on the front side of the movable block 404, and is guided by the positioning wheel 25. The movable block 404 can drive the saw blade to move up and down, and can convert the rotational motion of the driving source into the up and down linear motion of the saw blade, thereby realizing automatic cutting of the saw blade.

[0029] By adopting the above-mentioned decoration putty grinding device, the automatic grinding of the putty wall is realized, and the specific grinding method is as follows:

[0030] The grinding disc 3 is attached to the wall, and the driving motor 401 is started. Under the linkage action of the eccentric wheel 402, the linkage rod 403 and the push arm 406, the grinding disc 3 can slide up and down on the wall for grinding;

[0031] When the grinding disc 3 needs to be replaced, the grinding disc 3 is driven to move by the driving motor 401 until the grinding disc 3 slides to the point where the mounting groove 32 corresponds to the positioning groove 23, the hinge shaft can be unscrewed, and the grinding disc 3 can be slid out of the mounting seat 2, and then a new grinding disc 3 can be installed;

[0032] When it is necessary to use a saw blade for cutting, the grinding disc 3 can also be removed, and the saw blade can be installed at the knife groove 24 on the front side of the movable block 404, and then the saw blade can be driven up and down by the movable block 404 to achieve cutting.

[0033] The control method of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
