Further, a notch 61 is formed on the upper portion of the slider 60, a first supporting shaft is disposed on the inner wall of the notch 61 and perpendicular to the inner wall of the notch 61, the first supporting wheels 62 are sleeved on the first supporting shafts, a first annular groove 621 is formed on the outer portion of each first supporting wheel 62, and the polishing belt 31 flows in the first annular groove 621, so that the phenomenon that the polishing belt 31 is separated from the slider 60 in the process of pulling the polishing belt 31 by the slider 60, and the polishing belt 31 is loosened and cannot be effectively polished is avoided.
Further, the first supporting wheels 62 can rotate freely on the first supporting shafts, and friction force can be generated between the contact surfaces of the grinding belt 31 and the first supporting wheels 62 in the process of circulating the grinding belt 31 on the first supporting wheels 62, so that the first supporting wheels 62 can rotate freely on the first supporting shafts, and the generated friction force can drive the first supporting wheels 62 to rotate, so that negative effects caused by the friction force can be effectively counteracted, damage of the friction force to the grinding belt 31 and circulating speed of the grinding belt 31 can be reduced, and the grinding belt 31 can circulate smoothly on the path.
In this embodiment, as shown in fig. 1 to 4, the conveying frame 32 is further provided with a plurality of second supporting wheels 323 for supporting and guiding the abrasive belt 31. Specifically, through set up a plurality of second back shafts on the circulation route of abrasive belt 31 for each second back shaft is cup jointed correspondingly to each second back shaft, and the outside on each second back shaft 323 all is equipped with second annular groove 3231, and abrasive belt 31 circulate in this second annular groove 3231, thereby avoids abrasive belt 31 to break away from each second back shaft 323 and causes unable phenomenon emergence of grinding in the in-process that conveys support 32 to circulate, and then guarantees that abrasive belt 31 can circulate steadily on conveying support 32, guarantees butt welding needle grinding's persistence.
Further, each second supporting wheel 323 can freely rotate on each second supporting shaft, and in the process that the grinding belt 31 flows on each second supporting wheel 323, friction force can be generated between the contact surfaces of the grinding belt 31 and each second supporting wheel 323, so that the second supporting wheels 323 can freely rotate on each second supporting shaft, and the generated friction force can drive each second supporting wheel 323 to rotate, so that negative effects caused by the friction force can be effectively counteracted, damage of the friction force to the grinding belt 31 and the flow rate of the grinding belt 31 can be reduced, and the grinding belt 31 can smoothly flow on the path.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
