[0051] The working principle of the automobile waste tire cutting machine described in the present invention is: The operator first places the tire 3 to be cut vertically on the two round tubes 6 of the tire lifting frame 1. After the tire 3 to be cut is centered, the first driver 9 lifts the tire 3 to be cut until the center of the tire 3 to be cut is aligned with the center of the first outer expansion chuck 15. The operator moves the tire 3 to be cut toward the first outer expansion chuck 15, so that the four first outer expansion blocks 14 extend into the inner ring of the tire 3 to be cut. Then the four first outer expansion blocks 14 move toward the outer ring of the tire 3. After the tire 3 is tightened, the tire lifting frame 1 descends, and then the third driver 36 pushes the push frame 28 to move, driving the body platform 29 to move to the left until the second outer expansion chuck 24 is in contact with the outer ring of the tire 3. After touching the side of the tire 3 to be cut, the pushing is stopped. At this time, the four second outer expansion blocks 25 have extended into the inner ring of the tire 3 to be cut. Then the four second outer expansion blocks 25 move toward the outer ring of the tire 3 to tighten the tire 3. Then the third driver 36 continues to push the body platform 29 to the left until the second outer expansion chuck 24 presses the tire 3. Then the second driver 16 and the third driver 36 respectively drive the first outer expansion chuck 15 and the second outer expansion chuck 24 to rotate simultaneously, driving the tire 3 to rotate. Finally, the two saw blade feeding devices 5 / 52 extend the saw blades, and the two saw blades start to rotate and cut the tire 3 from both sides of the tire 3 at the same time.

[0052] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
