[0020] Specifically, the chain transmission system comprises a plurality of triangular transmission systems, each triangular transmission system comprising two double-row sprockets 10, a single-row sprocket 4 and a cam rotating chain 9, the double-row sprockets 10 are rotatably arranged on the T-shaped plate connecting shaft 12 at the connection between the inner T-shaped plates 6 and the outer T-shaped plates 7, the single-row sprocket 4 is fixed on the cam 3 through the cam shaft 5, the cam rotating chain 9 cooperates with the two double-row sprockets 10 and the single-row sprocket 4, when the cam rotating chain 9 rotates, the double-row sprockets 10 rotate on the T-shaped plate connecting shaft 12, the single-row sprocket 4 drives the cam 3 to rotate, and the cam 3 drives the outer T-shaped plates 7 on both sides to swing outward.

[0021] Since the double-row sprocket 10 is rotationally connected with the T-shaped plate connecting shaft 12, when the cam rotating chain 9 rotates, the T-shaped plate connecting shaft 12 in the double-row sprocket 10 idles, and the single-row sprocket 4 is fixed on the cam 3, so that the cam rotating chain 9 rotates, and the cam 3 rotates with the single-row sprocket 4; in addition, since the cam 3 is arranged between the two outer T-shaped plates 7, when the cam 3 rotates, the cam 3 will push the outer T-shaped plates 7 on both sides, and the outer T-shaped plates 7 will rotate by a certain angle after being pushed, and the position of the T-shaped plate connecting shaft 12 will also change, and after the multiple triangular transmission systems are linked, a linear arc is formed for the production of bent glass.
