[0043] The working process of the present invention is as follows:

[0044] When the curved decorative panel 7 needs to be polished, first move the transverse plate 512 to one side of the processing platform 2, pass one end of the curved decorative panel 7 through the two groups of polishing components 42, and fix the curved decorative panel 7 on the transverse plate 512 through the electric clamp 524 by adjusting the spacing between the two groups of clamping components 52.

The grinding rollers 424 in contact with the surface of the curved decorative panel 7 rotate to achieve grinding of the surface of the curved decorative panel 7.

[0046] The second motor 515 drives the lead screw 514 to rotate, causing the transverse plate 512 to move in a straight line at a uniform speed, thereby driving the curved decorative plate 7 to move synchronously. During the movement of the curved decorative plate 7, the curved decorative plate 7 is subjected to the squeezing force of the positioning roller 425 and the grinding roller 424, which will cause the curved decorative plate 7 to drive the electric clamp 524 to rotate and move, so as to ensure that the grinding angle and pressure of the grinding roller 424 remain uniform.

[0047] When the transverse moving plate 512 moves to the rightmost end, the inclined surfaces on both sides of the driving plate 61 support the two sliders 421, so that the two sliders 421 move away from each other, and the limit block 65 disengages from the limit stop bar 64, the rack 62 engages with the gear 63, and the gear 63 rotates to drive the connecting shaft 422 to rotate (rotate 180°) through the one-way bearing, so that the grinding rollers 424 and positioning rollers 425 of the two sets of grinding assemblies 42 switch positions; the transverse moving plate 512 moves in the opposite direction, and 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 positioning roller 425 contact the curved decorative plate 7 again, and the grinding roller 424 in contact with the curved decorative plate 7 rotates to realize automatic grinding of the other side of the curved decorative plate 7.

[0048] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
