When the conveying seat is transmitted to the bottom of the grinding mechanism, the driving motor drives the tensioning roller to rotate through the third gear, the fourth gear and the tooth block, so that the conveying roller rotates synchronously, and the sandpaper conveyor belt slides in the opposite direction on the upper surface of the special-shaped metal part to grind the burrs on the surface of the special-shaped metal part.

At this time, the second spring is also in a stretched state. The special-shaped metal parts in the middle are The parts are clamped and lifted, so that the upper surface of the special-shaped metal parts can more completely contact the sandpaper conveyor belt above. After the grinding mechanism completes the grinding of the special-shaped metal parts, the transmission chain continues to convey the conveying seat away from the lifting block. After the lifting of the lifting block is lost, the clamping block slides to both sides and releases the special-shaped metal parts through the reset effect of the first spring and the second spring, so as to automatically release the material and facilitate subsequent unloading.

When the lifting block 602 is rotated by the transmission shaft 3 of the driving motor 2, when the protruding part of the lifting block 602 is rotated to face upward, the lifting block 604 in the conveying seat 601 moved above the lifting block 602 is lifted upward. After the lifting block 604 is lifted upward inside the structural groove 603, the first spring 606 is in a stretched state. At the same time, the inclined surfaces of the triangular blocks 605 on both sides are squeezed to make the clamping blocks 608 on both sides slide toward the middle.

Since the number of teeth on the third gear 501 and the fourth gear 502 is greater than the number of tooth blocks 504 on the surface of the tensioning roller 503, the moving speed of the sandpaper conveyor belt 506 is greater than the conveying speed of the special-shaped metal parts, thereby improving the grinding effect. After the grinding process is completed, the conveying seat 601 continues to move and leaves the jacking block 602. The reset effect of the first spring 606 and the second spring 609 causes the clamping block 608 to slide to both sides to loosen the special-shaped metal parts. When the conveying seat 601 slides to the rightmost side of the transmission chain 403, the transmission roller 401 synchronously drives the first bevel gear 701 to rotate, thereby rotating the second bevel gear 703, the rotating shaft 702 and the turntable 704.
