[0026] Please refer to Figures 1-9 , the present invention provides the following technical solutions: A grinding device for decorative plates used in building construction, including a frame 1, a processing platform 2 is provided at the upper end of the frame 1, and a mounting bracket 3 is installed on the upper end surface of the processing platform 2; a grinding mechanism 4, the grinding mechanism 4 includes a mounting block 41 installed on the mounting bracket 3, two sets of grinding assemblies 42 and a compression spring 43, a chute is provided in the mounting block 41, and the two sets of grinding assemblies 42 are slidably connected to the chute in the mounting block 41, and a compression spring 43 for pushing the two sets of grinding assemblies 42 closer is provided in the chute; during grinding, the grinding roller 424 of one set of the grinding assemblies 42 contacts the surface of the curved decorative plate 7, and the two positioning rollers 425 of the other set of the grinding assemblies 42 contact the other surface of the curved decorative plate 7. By cooperating with the two positioning rollers 425 and one grinding roller 424, it can be ensured that the tangent a of the curved decorative plate 7 at the grinding assembly 42 is always perpendicular to the line connecting the axis of the grinding roller 424 to the tangent point b (as Figure 9 shown), ensuring that the grinding angle and pressure of the grinding roller 424 are uniform.

[0027] The grinding assembly 42 includes a slider 421 slidably connected in the mounting block 41, a connecting shaft 422 rotatably connected to the slider 421, and a mounting plate 423 connected to the lower end of the connecting shaft 422. A grinding roller 424 and two positioning rollers 425 are vertically rotatably connected to the lower end of the mounting plate 423. The grinding roller 424 and the positioning rollers 425 are arranged in a triangular structure, which is convenient for switching between two working states of support or grinding; the positioning roller 425 is a rigid roller for providing a stable supporting force.

[0028] A through hole is provided inside the connecting shaft 422. A driving shaft 426 is rotatably connected inside the connecting shaft 422. The lower end of the driving shaft 426 is in transmission connection with the grinding roller 424 through a transmission belt 427. A fixing plate is fixedly connected to the side wall of the connecting shaft 422. A first motor 428 for driving the driving shaft 426 to rotate is installed on the fixing plate. This transmission design can avoid the grinding space of the grinding roller 424 being occupied by the first motor 428.

[0029] A sheet material traction mechanism 5 is installed on the processing platform 2 and is used to traction and move the curved decorative board 7, and can cooperate with the grinding mechanism 4 to grind the curved decorative board 7 more evenly; the sheet material traction mechanism 5 includes a linear driving component 51 and a clamping component 52. The linear driving component 51 is installed on the processing platform 2 and is used to drive the curved decorative board 7 to move relative to the grinding mechanism 4. The clamping component 52 is installed on the linear driving component 51 and is used to clamp and fix the curved decorative board 7, and can make the grinding roller 424 evenly fit the surface of the curved decorative board 7 for grinding.

[0030] The linear driving component 51 includes a slide rail 511, a transverse moving plate 512 and a support 513. The slide rail 511 is horizontally installed on the processing platform 2. The transverse moving plate 512 is slidably connected to the slide rail 511. Supports 513 are installed on both sides of the processing platform 2. A lead screw 514 is rotatably connected to the support 513. The lead screw 514 is in threaded connection with a threaded hole below the transverse moving plate 512. A second motor 515 for driving the lead screw 514 to rotate is also installed on the processing platform 2; the second motor 515 can drive the transverse moving plate 512 to slide linearly.

[0031] The clamping component 52 includes a vertical plate 521, a transverse frame 522 and a vertical frame 523. The vertical plates 521 are installed on the left and right sides of the upper end surface of the transverse moving plate 512. The vertical plate 521 on one side of the transverse moving plate 512 is fixedly installed. The vertical plate 521 on the other side of the transverse moving plate 512 is horizontally slidably connected to the transverse moving plate 512, and a fixing component for positioning is installed on this vertical plate 521; the fixing component is a limit bolt 525, and the limit bolt 525 is vertically threaded on the bottom plate of the vertical plate 521; through this design, the distance between the two clamping components 52 can be adjusted to be suitable for curved decorative boards 7 of different lengths.

[0032] A transverse frame 522 is installed on the vertical plate 521, a vertical frame 523 is slidably connected to the transverse frame 522, and an electric gripper 524 is rotatably connected to the vertical frame 523; the electric gripper 524 can rotate and move horizontally, and can cooperate with the grinding assembly 42 to change the position of the curved decorative plate 7 according to the required state, so as to achieve a uniform grinding effect.

[0033] A processing surface switching mechanism 6, the processing surface switching mechanism 6 is installed on the sheet material traction mechanism 5 and the grinding mechanism 4, and is used for automatically switching the grinding surface of the curved decorative plate 7; the processing surface switching mechanism 6 includes a driving plate 61, a rack 62 and a gear 63, the driving plate 61 is installed at the upper end position of the vertical plate 521, the rack 62 is installed on both sides of the upper end surface of the driving plate 61, a gear 63 is connected to the connecting shaft 422 through a one-way bearing, the gear 63 can be engaged with the rack 62, a limiting block 65 is key-connected to the connecting shaft 422, and a limiting bar 64 for limiting the limiting block 65 is connected to the lower end surface of the mounting block 41; the setting of the processing surface switching mechanism 6 enables the two grinding assemblies 42 to switch directions after one side end surface of the curved decorative plate 7 is ground, so as to realize the automatic grinding process of the other side.

[0034] The working process of the present invention is as follows: When the curved decorative plate 7 needs to be ground, first move the transverse moving plate 512 to one side position of the processing platform 2, pass one end of the curved decorative plate 7 through between the two grinding assemblies 42, and adjust the distance between the two clamping assemblies 52, and fix the curved decorative plate 7 on the transverse moving plate 512 through the electric gripper 524.

[0035] At this time, the grinding roller 424 of one grinding assembly 42 contacts the surface of the curved decorative plate 7, and the two positioning rollers 425 of the other grinding assembly 42 contact the other surface of the curved decorative plate 7, and the grinding roller 424 in contact with the surface of the curved decorative plate 7 rotates to realize the grinding of the surface of the curved decorative plate 7.

[0036] The second motor 515 drives the lead screw 514 to rotate, so that the transverse moving plate 512 moves in a uniform straight line, thereby driving the curved decorative plate 7 to move synchronously. During the movement of the curved decorative plate 7, due to the extrusion force of the curved decorative plate 7 on the positioning roller 425 and the grinding roller 424, the curved decorative plate 7 will drive the electric gripper 524 to rotate and move, so as to ensure that the grinding angle and pressure of the grinding roller 424 are kept uniform.

[0037] When the transverse moving plate 512 moves to the rightmost end, the inclined surfaces are arranged on both sides of the driving plate 61 to support the two sliders 421, so that the two sliders 421 move away from each other, and the limiting block 65 is disengaged from the limiting bar 64. The rack 62 meshes with the gear 63, and the rotation of the gear 63 drives the connecting shaft 422 to rotate (rotate 180°) through the one-way bearing, so that the positions of the grinding rollers 424 and the positioning rollers 425 of the two sets of grinding assemblies 42 are switched; when the transverse moving plate 512 moves in the reverse direction, the driving plate 61 gradually disengages from the slider 421 (under the action of the one-way bearing, the connecting shaft 422 does not rotate), and the two sliders 421 move closer to each other under the action of the compression spring 43, so that the grinding roller 424 and the positioning roller 425 contact the curved decorative plate 7 again, and the rotating grinding roller 424 in contact with the curved decorative plate 7 realizes the automatic grinding of the other side of the curved decorative plate 7.

[0038] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
