The utility model relates to a sealing device, in particular to a corrugated pipe sealing device of a float glass edge roller, which belongs to the field of float glass production machinery. The corrugated pipe sealing device comprises a front plate, a rear plate and a corrugated pipe, and is characterized in that the front plate (1), the corrugated pipe (2) and the rear plate (3) are integrally connected, the middle of each of the front plate (1) and the middle of the rear plate (2) are respectively provided with a hole, one side of the front plate (1) is connected onto the side wall of a tin bath (9), one end of a press plate (4) is connected onto the rear plate (3), the other end of the press plate (4) extends into the corrugated pipe (2), the middle of the press plate is in a structure of a cylinder, a central hole is arranged inside the cylinder a graphite sleeve (5) is arranged in the center hole and is hermetically fit with the central hole and the outer wall of an edge rolling rod (8), the press plate, the graphite sleeve and a stopping plate are in splitting structures which are provided with cutting seams (7). Compared with the prior art, the corrugated pipe sealing device of the float glass edge roller has the advantages of capabilities of preventing leakage of pressure of the tin bath effectively and reducing resistance between the edge rolling rod and the rear plate when the edge rolling rod moves, and the operation of detaching an edge rolling wheel before detaching the corrugated pipe is omitted.
