The dynamic water seal roller comprises a roller; a free end of the roller is coated with a bearing and a bearing cover in sequence; a water inlet shaft pipe is sleeved in an inner hole of the roller; the end part of the roller is coated with a rotating joint; the rotating joint includes a shell; an outer pipe rotating body is sleeved in the shell; a hollow pipe is sleeved in the outer pipe rotating body; a water inlet and a water return port are formed in the shell; the water inlet is in butt joint with the water inlet shaft pipe through the hollow pipe; the outer pipe rotating body is coated with a shaft core; a cavity formed between the inner hole of the roller and the outer wall of the water inlet shaft pipe is communicated with a cavity formed between the inner wall of the outer pipe rotating body and the outer wall of the hollow pipe through the shaft core; and sealing rings are respectively sleeved between the shaft core and the inner hole of the roller and between the shaft core and the outer pipe rotating body. The dynamic water seal roller realizes cooling of the roller during roller rotating, prevents high-temperature damage of the roller and the bearing, prolongs the service life of the roller, is provided with multiple sealing rings in the rotating joint to achieve a dynamic water seal effect in a cooling system joint, and reduces leakage of cooling water.
